Abstract

A method of monitoring a torque transmission system with a manually switchable gearbox in the power train of a motor vehicle involves the utilization of at least one sensor unit at the input side of the torque transmission system to ascertain relevant positions of the shift lever of the gearbox and the driving torque of the engine of the motor vehicle. The thus obtained shift lever signals are memorized, together with comparison signals which are obtained as a result of filtering of the shift lever signals, and various characteristics of such signals are recognized and identified to indicate the intention of the operator of the vehicle regarding the switching of the gearbox. The thus obtained switching intention signals are transmitted to a controlled clutch operating system.

Description

The method for supervising that is used for moment transmiting system

The application is that application number is: 95102115.X, the applying date are: February 23, denomination of invention were in 95 year: the control method of moment transmiting system and the dividing an application of moment transmiting system of implementing this method.

Technical field

The present invention relates to a kind of monitoring method of moment transmiting system, the control method of moment transmiting system and a kind of moment transmiting system of implementing this control method.

Background technology

In vehicle technology, when between driving machine and gear unit, changing speed ratio or shelves level, need control and speed governing calculating the clutch process support or make it automation, this is well-known.Therefore, the manipulation of engine unit and actuator unit should be very easy to, and the clutch process realizes the fuel saving and the energy as far as possible.In addition, the control of moment transmiting system (automatic transmission with hydraulic torque converter of packing into after this system) convergence is to bearing and guaranteeing that for example conical disc has been to apply to use around the control process and the defencive function of driving device.

Control method about the moment transmiting system that interrelates with automatic transmission with hydraulic torque converter among the WO94/04852 is known.Moment transmiting system has a band to be set in parallel in the power shunt of friction clutch turbine transformer.In the method,, resolve into a hydraulic pressure component and a mechanical component of transmitting by friction clutch (as bridging clutch) of transmitting by tor-con by the drive torque that driving engine provides.Central Processing Unit (CPU) or computer unit, with the dependence of system's operative condition, determine or calculate by the friction clutch torque transmitted.The excess torque of being transmitted by turbine transformer from applying moment and by producing the difference between the friction clutch carry-over moment, and directly is equivalent to skidding between the driving of moment transmiting system and hunting gear.

This control method has only to interrelate with automatic transmission with hydraulic torque converter and bridging clutch and just can get involved use.Yet, get involved in the scope of using numerous the need, have only minority can accept automatic transmission with hydraulic torque converter.In addition, such bridging clutch cost is too high, takes up an area of too big.

Summary of the invention

Task of the present invention is, a kind of method for supervising that is used for moment transmiting system is provided, and it has overcome the shortcoming of this method in the prior art.

Other task of the present invention is to create a kind of general as far as possible and can get involved the control method of use, the load property that this method should have high control quality and obviously improve moment transmiting system.

In addition, in contrast to conventional moment transmiting system, answer the advantage on the acquisition cost.From this point, also should create a kind of moment transmiting system of implementing this type of control method.

According to the present invention, a kind of method for supervising that is used to the moment transmiting system of manual shift driving device has been proposed, in the method, detect the drive torque of the drive side driver element of relevant gear level position and belt sensor, and write down at least one corresponding gear level signal and at least one comparison signal, and the various possible characteristic that changes of distinguishing signal, identification gearshift intention, and the intention signal of then will shift gears is defeated by the clutch actuation system of back setting.

According to the present invention, make the clutch torque that to transmit from moment transmiting system drive side to slave end as the controlled variable utilization with or without the power shunt; Here, this controlled variable is to calculate with the dependence of drive torque and/or to determine.

Thus, will realize moment tracking notion.The basic thought of these class methods is, makes the setting device ground convergence control of preponderating like this: by the transferable clutch torque of torque transmission member, make it a little more than or be lower than the drive torque that puts on the moment transmiting system drive side.

Generally, moment transmiting system must doubly design by the 2-3 of driving machine (as driving engine) maximum drive moment.Yet the drive torque of typical run is the sub-fraction of maximum drive moment.Moment is followed the tracks of and is allowed to replace quasi-continuous over-pressure tightness, and only produces the power stream of actual needs between the torque transmission member.

Another advantage is the application in this control method.Different with governor is that the feedback of moment transmiting system state parameter does not press for.This can have raising slightly to the control quality individually, but also nonessential to the generation of moment transmiting system function.The task of this type of moment transmiting system is a transmitting torque.Therefore, transferable clutch torque is highly significant as controlled variable.

A very favourable expansion of the present invention, it is characterized in that: in the method for control (this method control from the drive side of moment transmiting system to the transferable moment of slave end), comprise that test value surveys sensing system and the control unit that interrelates with it thus or the computer unit of usefulness with or without power moment transmiting system along separate routes; At this moment, control like this, make transferable torque, and departing from by proofreading and correct for a long time of perfect condition compensated as the function calculation of drive torque, adaptive and control by the transferable torque of moment transmiting system.

In addition, if this method is applied to the particularly control of the moment transmiting system of automobile, then can be highly beneficial; Here, behind the moment transmiting system of driving machine in the insertion force stream, speed ratio variset (as change-speed box) is then pre-insert or back insertion force stream in, and control from the drive side of moment transmiting system to the transferable torque of slave end; Comprise a control unit or computer unit, they are in the signal contact state with sensor and/or other electronic unit; At this moment,, and adapt to control, and departing from by proofreading and correct for a long time of perfect condition compensated by the function calculation of the transferable torque of moment transmiting system as drive torque.

According to another expansion, controlled variable utilizes a setting device (adjustment data that one of this device regulation and transferable clutch torque is had functional relation) to control like this: within the tolerance band that centers on the limit of skidding that transferable clutch torque is positioned at all the time can stipulate; At this moment, if be present in the effect of the torque of drive side, surpass by the transferable clutch torque of torque transmission member, then this limit of skidding just can reach.

Particularly according to this expansion, this method can be implemented like this: by moment transmiting system (as friction clutch, and/or with or without the turbine transformer of tor-con bridging clutch, and/or automatic transmission with hydraulic torque converter starting clutch, and/or reversing clutch, and/or the moment transmiting system of the stepless adjustable drive that inserts in advance or afterwards insert, as conical disc around driving device) transferable torque, function as drive torque is controlled like this: in the system of drive rate shunt (as the turbine transformer of band tor-con bridging clutch), tried to achieve by following moment equation by the transferable torque of power-transfer clutch:

K _KSoll=K _ME* M _ANWith

M _Hydro=(1-K _ME) * M _ANHerein, these two equations are suitable for K _ME≤ 1, and

M _Ksoll=K _ME* M _ANWith

M _Hydro=0 is suitable for K _ME＞1, in the formula:

K _ME=moment partition ratio

M _Ksoll=power-transfer clutch rated moment

M _AN=apply moment

M _Hydro=by the moment while that turbine transformer transmits, put on the moment M of moment transmiting system by actuating unit _ANWith by the transferable moment M of power-transfer clutch _KsollBetween torque difference, by the turbine transformer transmission; Here, moment transmiting system drive and hunting gear between minimum skid, regulating independently, grasp, handle and departing from of perfect condition adapted to, and compensated for a long time with the dependence of moment partition ratio.

Another kind of the method according to this invention is modified to, and by the transferable torque of moment transmiting system, controls like this as the function of drive torque; At inactivity along separate routes (as friction clutch, and/or starting clutch, and/or reversing clutch, and/or automatic transmission with hydraulic torque converter or stepless adjustable drive one just like conical disc around driving device) system in, try to achieve by friction clutch or the transferable torque of starting clutch

K _KSoll=K _ME* M _ANAnd to K _ME〉=1, will produce the certain compaction degree excessively of torque transmission member.

Further, when controlling like this as the function of drive torque by the transferable torque of moment transmiting system, then can be very favourable: at inactivity along separate routes (as friction clutch, and/or starting clutch, and/or automatic transmission with hydraulic torque converter and/or stepless adjustable conical disc are around the moment transmiting system of driving device) system in, try to achieve by the transferable torque of moment transmiting system

M _Ksoll=K _ME* M _AN+ M _Sicher, and to K _ME＜1, virtual power is simulated the characteristic of the moment transmiting system (as turbine transformer) of parallel access, simultaneously along separate routes by underlaid control loop line, but the one-component of transmitting torque is through the convergence control of Torque Control mechanism, and remaining torque is through a safe moment M _SicherWith the relevant ground control again of skidding.

In addition, when safety moment to regulate with the dependence of each operation point, may be very favourable.

Equally, when the functional relation of safety moment, press with skid Δ n or throttle valve position d

M _Sicher(Δ n d) tries to achieve=f, and/or control, and is then also very helpful.

Equally, safe moment M _SicherPress

M _Sicher=constant * Δ n tries to achieve, and/or control, also is appropriate.

Further, as moment partition ratio K _MEWhole operating range through the section of overdriving keeps constant, then is very much favourable.

Equally, following situation is also very useful: partition ratio K _MESuppose the individual values that records from certain operation point, and/or suppose it is to be steady state value at least that in the part scope of operating range, the value of regulating can be different here in different part scopes.

Therefore, this may be a vantage also: be about to whole operating range part scope, here, K in the various piece scope _MEIt is constant that value keeps, and keep constant K _MEValue can change to another operating range from an operating range.

In addition, as moment partition ratio K _MEWhen functional relation being arranged with driving rotating speed and/or car speed, can be very favourable.

According to the thought that adapts with the present invention, only relevant when the value of moment partition ratio KME with the rotating speed of actuating unit, be favourable also.

Equally, when the value of moment partition ratio at least in the part scope in whole operating range both with the rotating speed of actuating unit, also relevant with its torque, then can be highly beneficial.

In addition, as moment partition ratio K _MEValue both also relevant with its moment with the driven rotating speed of actuating unit, can be very helpful.

In addition, when basically to each time point by the certain specified clutch torque of moment transmiting system transmission, also can be favourable.At this moment, when transferable torque tracking has moment now, then very appropriate.

This expansion has the following advantages: promptly the compaction degree of moment transmiting system not necessarily must keep its peak forever.According to the prior art situation, moment transmiting system (as power-transfer clutch) will produce with many signals of driving engine nominal moment and impact.

In the automated torque transmission system, but introduce the tracking of transmitting torque here, make adjuster and mobile not only when gearshift and starting, convergence is controlled it and is opened and close process, but make adjuster in each operation point with transferable torque adjustment to the value suitable at least basically with rated value.

In order to make adjuster and mobile needn't be for a long time in tracking movable, but cross the control of compaction degree convergence with one when the transmitting torque of a moment transmiting system, and this is crossed compaction degree and is positioned at the narrower dispersion train that is relevant to rated value, then is very suitable.

It is relevant with the operation point to have served as compaction degree Δ M, then very appropriate.

When operating range part scope, and each part scope is all determined its compaction degree and/or crossed compaction degree, then advantageous particularly.

In another expansion of the present invention, when compaction degree and/or cross compaction degree and/or transferable clutch torque changes in time and carries out convergence control, then has very big advantage.

Equally, according to contriver's thought, when the clutch torque transmitted that will regulate is no more than minimum M _Min, be very much favourable.This minimum and operation point and/or instantaneous operating range and/or time are relevant.

In addition, moment follow the tracks of by change in time, implement by the specific guiding in operation point and the combination of minimum, can be very much appropriate.

Thought according to the contriver, then following situation is very favourable: the operation point of moment transmiting system and/or combustion engine or mode of operation, by the state parameter that records or calculate from test signal (as the relation of engine speed and throttle gate opening angle, the relation of engine speed and fuel flow, the relation of engine speed and suction pipe negative pressure, the relation of engine speed and injection time, perhaps temperature and/or friction coefficient and/or skid and/or the relation of load beam and/or load beam steepness) determine.

Favourable situation is, be installed in the moment transmiting system of combustion engine of drive side at band, the drive torque of combustion engine is determined as engine speed, throttle gate opening angle, fuel flow, suction pipe negative pressure, injection time or temperature at least by one in the state parameter of operation point.

The modification of another this method is: the torque M that puts on the moment transmiting system drive side _AN* K _ME, be subjected to influence and/or variation by the relation of the calculating of system dynamics supporting, here, the dynamics problem of system can be caused by the dynamic characteristic based on moment of inertia and/or relief angle and/or damping element.

Make when existence system the power servo-actuated the method being controlled or influence, may be very favourable.

Equally, when influencing M _AN* K _MESystem dynamic realize with the form of gradient restriction, also very useful.

The increment limit that the gradient restriction can be used as permission realizes.

In addition, following situation may have advantage: the gradient restriction realizes like this: make over time and/or the time dependent rising of signal, compare with a maximum gradient or a slope function that allows, simultaneously, when surpassing the increment of maximum permission, this signal is replaced by the substitute signal that increases by the gradient of prior regulation.

In addition, following situation also has advantage: the dynamic effect of system or restriction, show the time constant and/or the amplification rate time to time change of characteristic here according to screening sequence principle design current power and/or changeable, and/or relevant with the operation point.

Vantage is that the dynamical problem of system can be considered to use the PT1 screening sequence, and/or handles.

Equally, if system dynamic shows by threshold limit value, be very much favourable; Here, when surpassing certain limit value, rated value is represented by limit value, and corresponding rated value can not surpass the maxim of being represented by limit value.

In addition,, use as gradient restriction and the series connection of screening sequence level when the method that has at least two kinds to influence system, can be highly beneficial.

Equally, when the method that has at least two kinds to influence system, as gradient restriction and screening sequence use in parallel, can be very favourable.

Particularly advantageous is that the power of combustion engine and the power of facilitating power additional energy consumer along separate routes are at definite drive torque M _ANIn time, take in.In this case, as when consideration is combustion engine powered, adding the moment of inertia of each mass of flywheel and/or element, then beneficial especially.

Equally, when the injection characteristics that adds combustion engine when considering the power of combustion engine, and/or considering based on this, is very much favourable.

Equally, according to control method of the present invention, to departing from of perfect condition, can be by consideration to additional energy consumer, and/or, give long-term compensation to disturbing and/or the correction and/or the counteracting of interference source.

When the torque that puts on moment transmiting system receive as engine moment and additional energy consumer or shunting torque summation between difference detect and/or calculate, may be very favourable.As what additional energy consumer typical case will consider be: air conditioner and/or light machine and/or servopump and/or assisted control pump.

Be adapted to contriver's thought, following situation is very helpful: at definite engine moment M _MotValue the time add system status parameters, these parameters are as engine speed and throttle valve angle, engine speed and fuel flow, engine speed and suction pipe negative pressure, engine speed and injection time, engine speed and load beam etc.

Further, by system status parameters, engine moment M _MotFrom the characteristic curve of driving engine, try to achieve, may be favourable.Adapt therewith, at definite engine moment M _MotThe time add state parameter, and engine moment is determined by separating at least one equation or a set of equations, and is then favourable equally.Equation or solution of equations can pass through Digital Implementation, and/or try to achieve according to the characteristic curve data.

In addition, following situation also is favourable: the reception moment of additional energy consumer and shunt power are determined by test parameter, the voltage of these parameters such as light machine and/or current value, and/or the access signal of each additional energy consumer, and/or the signal of the additional energy consumer mode of operation of other expression.

In addition, the reception moment of additional energy consumer is determined by the test parameter that obtains from each additional energy consumer characteristic parameter, may be very much convenient.Equally, the reception moment of additional energy consumer can be by separating at least one equation or a set of equations is determined.

According to contriver's thought, following situation is very appropriate: the transferable clutch torque of having proofreaied and correct can be pressed

M _Ksoll=K _ME* (M _AN-Mkorr)+M _SicherDetermine, provide by compensation value and proofread and correct moment Mkorr, this value with add the machine group of received or shunt the moment sum relevant.

Further, when the interference that testable system input parameter is exerted an influence gives to proofread and correct, then very useful.

Particularly advantageously according to method of the present invention be, testable interference parameter is grasped and/or discerned, and be fitted to small part by parameter adaptation and/or system and be compensated and/or revise.Further, the system input parameter of utilization is differentiated interference parameter, and/or revises and/or recompense to small part by parameter adaptation and/or system are adaptive, may be also very favourable.

Be to differentiate interference parameter, and/or revise and/or recompense to small part that system's input parameter (for example temperature, rotating speed, friction coefficient and/or skid) can be used as controlled variable and uses by parameter adaptation and/or system are adaptive.

Be that compensation and/or the correction that can test interference parameter realize by the adaptive of motor characteristic curve to this method advantageous particularly part.

In this case, fully following situation may take place: the interference parameter of observing or recording, its cause not necessarily must have relation with the characteristic curve of driving engine, yet the correction of this interference parameter may be passed through the adaptive more favourable of motor characteristic curve.In this case, the cause of interference parameter is not revised or compensated.

This can be another advantage, promptly produce a correction characteristic curve the comparison between power-transfer clutch rated moment and the actual moment of power-transfer clutch, and to trying to achieve or can be each operation point in the hope of compensation value, this value and the engine moment value of trying to achieve from motor characteristic curve additionally and/or multiplication combine.

In addition, suitable especially is, introduces to depart from analysis of carrying out and/or the measure of taking between the rated value that records according to an operation point and the actual value, to calculate and/or to determine departing from and/or compensation value in other operation point of whole operating range.

Further advantageously, introduce according to what an operation point recorded and depart from analysis of carrying out and/or the measure of taking, to calculate or to determine to limit departing from and/or proofreading and correct of other operation point in the operating range.When the operating range that limits is determined by characteristic relation, very favourable for this method.

Very favourable situation is an implementation of the present invention, it is characterized in that: depart from analysis of carrying out with compensation value and/or the measure of taking for determining and/or calculating in other operation point, take into account operating range whole or that limit.

Another favourable part is, calculates departing from and/or compensation value and analysis of carrying out and/or the measure of taking include only the real work point in the part scope in other operation point.Particularly advantageously be, when determine and/or calculate in other operation point depart from and/or during compensation value, can realize like this: the coefficient of weight of different range in the whole operating range should have and estimate or weighting regionally.

When coefficient of weight is selected and/or calculating as the function of operation point, very favourable.Equally, coefficient of weight can be relevant with the cause of the type of interference parameter and/or interference, also can benefit.

In addition, particularly advantageous is after definite compensation value and/or correction characteristic curve weighting, to print the time response of compensation value.This time response can typically be taken into account the dynamic characteristic of system.

When the time characteristic by impulse rate, i.e. the scanning of compensation value determines, and (or) this time response determines that by screening sequence at least one numeral and/or simulation this can be very favourable.

In expansion of the present invention especially meaningfully, to different interference parameters and/or different interference sources, time response will change to some extent: that is to say that under the situation of using screening sequence, the parameter of screening sequence is to regulate with the type of interference source and the dependence of mode.Therefore the time constant of screening sequence and amplification rate need and relevant interference source coupling, as well as possible adaptive to guarantee.

Time response is by selecting with the dependence of compensation value, and is very favourable.When drive torque carries out adaptive, then superior especially with the time constant that the time constant of adaptation processing is greater than or less than the clutch torque adaptation processing.When the time constant is positioned at the 1-500 scope of second, yet preferably in 10-60 second, and particularly preferably in 20-40 scope second, be very much favourable.

In another constructional variant, most suitable is, time constant is relevant with the operation point, and/or time constant is differently selected and/or determined in each different operating range.Further advantage is, can test the compensation and/or the correction of interference parameter, and by the transfer unit of band setting device, its contrary the adaptive of propagation function realizes.

The modification of this method that another is favourable is pointed out: non-ly directly can test interference parameter, wearing out and/or dispersing (Streuung) of the framing member everywhere of special as moment transmiting system grasped like this; Monitor the characteristic parameter of right dried moment transmiting system, and from this monitoring relation, discern and revise the actual parameter of disturbing, and/or get involved the virtual interference source that to connect, with the influence in correction and/or compensate for disturbances source with the form of procedural model.

Advantageously, never testablely influence the interference that produces in the parameter, as each framing member disperse and/or aging, detect and/or compensate by departing from of system status parameters.Further advantageously, as disperse or aging or else can not survey interference such as influencing parameter, do not detect, and just distinguish by the reaction of observing system from testing the input parameter.

Equally, favourable situation can be, system status parameters or from system response the departing from of observed state parameter, will directly measure and/or from the transaction module of other test parameter.Also advantageously, from the transaction module that calculates, discern and depart from, realize by reference characteristic curve and/or mono-system reference characteristic parameter.

Another favourable continuation development of the present invention is: for proofread and correct and/or compensation from surveying the interference that identifies the input parameter, will locate an interference source and/or definite interference source, and departing from of bringing of these interference sources revised and/or compensate.In addition, this may suit: be the interference that correction and/or compensation identify, determine a virtual interference source (it needn't be responsible for causing to disturb), revise detected departing from thereon.

Under vantage, the interference source of determining can be an in esse function block, and (or) interference source determined still virtual interference model under the prerequisite that keeps correcting action.

Adapt with continuation of the present invention development, the actual moment of power-transfer clutch is monitored, and set out thus and analyze: whether can be consistent with conclusion about the location of the identification of error pattern and/or interference source and/or interference source.

Correction to the interference parameter suitability is carried out for a long time, and this is very favorable.

Another favourable formation is: the suitability of interference parameter is only proofreaied and correct in certain operation point and/or certain operating range and/or time range and is implemented.

Further advantage is: if control is inactivity, then adaptive also can be avidity.Inactivity can be understood with such relation: promptly this control is not stipulated or avidity synthetic or the realization setting device, because can select or physical presence representative type operating range, in this scope, do not carry out moment and follow the tracks of, but regulate a stationary value.In this operating range, can carry out the adaptive of parameter, and not carry out movable control.

Further vantage is in specific operating range, when particularly seriously quickening, can not carry out adaptive.

This is very appropriate, promptly in the adaptive operating range of non-activity, and the compensation value of service adjustment parameter, this value records in the movable adaptive operating range that records in advance.From this point, this value that records in advance is stored in the middle memory for adaptive, and takes out in the adaptive situation of non-activity, and is more appropriate.

Concerning another kind of version of the present invention, this may be suitable, in the adaptive operating range of non-activity, uses the compensation value of interference parameter, and this value is extrapolated from the compensation value of the movable adaptive operating range that records in advance and got.

Adapt with the present invention's another kind method, this may be very appropriate, promptly to the virtual interference model and/or the virtual interference parameter of engine moment scope and/or clean engine moment scope, according to additional energy consumer and/or carry out adaptive to the power-transfer clutch rated moment.

In addition, when the transfer unit of band setting device, when its contrary propagation function got involved and/or uses as virtual interference source, this was very favorable.

Equally, when motor characteristic curve uses as virtual interference source, also be very much appropriate.

Particularly advantageously be, get involved virtual interference source, define interference parameter like this: promptly its prime cause be can not determine the position person, for example, and dispersing in each framing member production tolerance scope.

Another invention thought of the present invention relates to a kind of control method, is used for or without power moment transmiting system along separate routes; In this system, by the drive side of moment transmiting system to the transferable clutch torque of slave end, use as controlled variable, and this controlled variable is by a setting device (it is by with clutch torque emic adjustment data defined being arranged) control like this: transferable clutch torque is positioned at all the time can predesignate within the tolerance band of the limit value that skids; Here, surpass by the transferable clutch torque of torque transmission member if be present in the effect of the torque of drive side, then this limit value that skids will reach exactly.

Further advantageously, predesignate a value to setting device, as adjustment data, transferable clutch torque is suitable between the torque transmission member of this value and moment transmiting system.

Another significant continuation development of the present invention is: adjustment data is by determining with the dependence that can transmit clutch torque; And be to calculate this can transmit clutch torque, from constituting a difference between drive torque value and correction parameter, here, this correction parameter raises with the dependence with at least one state parameter of moment transmiting system or reduces.

Further meaningfully, correction parameter by and driving and driven rotating speed between the dependence of the speed discrepancy represented with the rotating speed that skids determine that at this moment, as long as the rotating speed that skids is lower than the limit value that skids of regulation, correction parameter raises; Rotating speed is higher than this limit value that skids that there is no other regulation as long as skid, and then correction parameter reduces.

Further advantageously, as long as the rotating speed that skids is lower than the limit value that skids, correction parameter raises trace; Rotating speed is higher than this value or other limit value that skids as long as skid, and correction parameter will reduce step by step; At this moment, between at different levels, tacky state is positioned at adjustable time cycle, and in this cycle, it is constant that correction parameter remains on that value of being transferred to when tacky state begins.

In addition, favourable situation is, drive rotating speed surpass with certain rotating speed that skids driven rotating speed during this period of time in, be considered to slipping state, after this slipping state finished, compensation value placed the value of regulation again.

The appropriate expansion of the present invention is: drive rotating speed surpass with certain rotating speed that skids driven rotating speed during this period of time in be considered to slipping state, simultaneously, that correction parameter when the rotating speed that skids is assumed to its maxim, be stored in the middle memory, and after slipping state finished, actual correction parameter was at that time replaced by the correction parameter of storing again.

Same favourable situation is that in cycle regular time, that correction parameter after slipping state finishes will keep its value at that time constant.Other expansion according to the present invention, its favourable part is: provide a specified value relevant with characteristic or characteristic curve in advance for setting device, this device comprise might transmit the scope of clutch torque, or display part scope at least, all transferable clutch torque are only given a specified value to this setting device in the scope in this section.

Another superior part is for calculating transferable clutch torque, form a difference from drive torque value and correction parameter, and this difference to increase with skidding relevant moment values with centering on.

The expansion further superior with the present invention adapts, its usefulness is: the increasing of actual clutch moment, mode with the gradient restriction is limited like this: the actual value that makes transferable clutch torque, with one relatively moment values compare, this comparative figure is made of the transferable clutch torque value that records in advance and additional, fixable limits value; And the less moment values that obtains from this comparison will provide as the new specified value of setting device.

Particularly advantageously be, grasp is installed in the more state parameter of explosive motor of moment transmiting system drive side, for example engine speed, throttle gate opening angle and/or suction pipe pressure, and the drive torque of trying to achieve explosive motor by the characteristic curve of storing or family of characteristic curves from these state parameters.In addition, the present invention also is: roughly the power between actuating device and moment transmiting system along separate routes, monitor at least in part or in short time, and consequent test parameter adds among the calculating of the drive torque that actually exists in the moment transmiting system drive side.

Advantageously, utilize the drive torque part that adapts with component coefficient, calculating transferable coupler moment, and this component coefficient is determined according to family of characteristic curves or the characteristic curve stored.

In addition, in not with power moment transmiting system along separate routes, by power of underlaid control program simulation along separate routes, be very appropriate.

According to contriver's thought, its preceence is: grasp can be tested interference parameter, and is special in temperature and/or rotating speed, and recompenses at least in part by parameter adaptation and/or by system is adaptive.

Significant continuation development is: the non-direct testable interference parameter of control method, the wearing out and/or disperse of special as each framing member of moment transmiting system, grasp like this: the state parameter of monitoring some moment transmiting systems, simultaneously, the actual parameter of disturbing of identification from this monitoring relation, and proofread and correct, and (or) get involved the virtual interference source that can connect with the form of procedural model, so that the influence of interference parameter obtains MIN correction and/or compensation.

Advantageously, the engagement of power-transfer clutch only just may be carried out later in the legal check of user.

Also advantageously, a kind of telltale (as user display) is to control with the relation of control method present situation: a gearshift of user proposed standard is provided.This gearshift proposed standard can be through telltale with optics, or another kind of situation realizes with form and the method for acoustics.

Favourable part in addition is, dead ship condition (particularly vehicle) by monitoring tangible working parameter, is differentiated as fuel pedal position and/or gear level position and/or speed meter rotating speed; And surpassing the specific time cycle, driver element stops, and resets when needed.

Further advantageously, the mode of operation of moment transmiting system has only very little or do not have load to reduce at all with this idling conditions and differentiate, and power-transfer clutch unclamps in this idling conditions, and finishes the back power-transfer clutch at idling conditions and connect.The end of idling conditions can typically take place by detecting load beam change in location and/or load beam steepness thereupon and distinguish.

Another expansion according to the present invention, for supporting antiblock device, control method can be controlled like this: power-transfer clutch will be thrown off fully in the response of ABS system.

Favourable in addition part is that setting device carries out convergence control according to the anti-regulation of regulating of skidding in the operating range of determining.

A kind of method of being not only above-mentioned controlling torque transmission system that the present invention relates to, and particularly relate to a kind of moment transmiting system from drive side to the slave end transmitting torque, in this system, drive side is installed combustion engine (as driving engine), and slave end is installed change-speed box; Moment transmiting system shows power-transfer clutch, setting device and control instrument simultaneously.

In addition, the present invention relates to a kind of moment transmiting system, it can utilize above-described method convergence control, and is used for the transmission of drive side to the slave end torque; In this system, the slave end of moment transmiting system inserts in power stream or driver element of back access in advance, as combustion engine, and inserts in advance in power stream or speed ratio variset of back access, as change-speed box; This moment transmiting system shows or comprises a power-transfer clutch simultaneously, and/or the tor-con of a band bridging clutch, and/or a starting clutch, and/or a reversing clutch, but and/or the safety clutch of restriction transmitting torque, a setting device and a control instrument.

According to thought of the present invention, particularly advantageous is that power-transfer clutch is a kind of power-transfer clutch of self regulating or self regulating again.

Also advantageously, for example wearing and tearing of friction lining can be adjusted and compensate to power-transfer clutch independently again.

Thought according to the contriver, favourable part is in expansion of the present invention: for from drive side to the slave end transmitting torque, moment transmiting system shows a setting device and a control instrument, here, power-transfer clutch is linked together effectively through a conduit under fluid pressure (it is shown as power-transfer clutch and accepts cylinder) and setting device, and setting device is controlled by the control instrument convergence.

Another advantage is the application of setting device, this device has an electromotor, it sends cylinder through a camming action in a hydraulic pressure, and this cylinder is connected on the conduit under fluid pressure that is linked together with power-transfer clutch, and clutch stroke sensor is then packed among the shell of setting device.

On the space-saving meaning and the flexible solution of settling by equipment of the present invention, its advantage is: electromotor, cam, transmission cylinder, clutch stroke sensor, and necessary control and power electric device are installed in the shell of setting device.

Same advantage is that the axle of electromotor and transmission cylinder is provided with in parallel to each other.Particularly advantageous is that electromotor divides in two different planes parallel to each other with the axle that sends cylinder, and is linked together effectively through cam.

Further advantageously, the axle of electromotor is parallel through a main plane that is made of the wiring of control and power electronic circuit.

According to the continuation of moment transmiting system of the present invention development, if in the shell of setting device, install one with the concentric spring of transmission cylinder, the function of moment transmiting system can reach optimization.

Favourable part in addition is: in sending the shell of cylinder, install one with the concentric spring of transmission cylinder axle.

According to the function of present device, its preceence is: the elastic curve of spring is adjusted like this: make by electromotor to be opening of power-transfer clutch and to close spent maximum, force, drawing and pressing on the direction near onesize.

Further advantageously, the elastic curve of spring designs like this: make the distribution that acts on the composite force on the power-transfer clutch, the moving process of process power-transfer clutch is rendered as linearity.According to continuing development, the power consumption and and then the electromotor size that will pack into can reduce.The power required to the throw-out-of clutch process, to determining that the motor dimension that will pack into plays a decisive role, because the disconnecting process of power-transfer clutch needs bigger application force than its engagement process, and the application force of spring can be supported disconnecting process, thereby can make the power designs of electromotor get smaller.

In the piston that sends cylinder, use spring, do not need to the extra position of spring.

In addition, this can be an advantage, and promptly electromotor acts on sectional wheel with its driven shaft through a worm screw, and this sectional wheel is equipped with a throw crank, and this crank is linked together so effectively through a piston rod and the piston that sends cylinder: pulling force and pressure can be transmitted.

Favourable situation is that worm screw and sectional wheel constitute a wheel word from interlocking equally.

What the present invention relates to is not only above-mentioned a kind of method about the controlling torque transmission system, with moment transmiting system itself, and relate to a kind of moment transmiting system method for supervising with stick transmission, in the method, detect the drive torque of the drive side driver element of relevant gear level position and belt sensor, and write down a corresponding gear level signal and at least one comparison signal at least, simultaneously, the various possible characteristics (for example difference) that these signals change are discerned, and distinguish as gearshift intention, be intended to signal and be defeated by clutch actuation system and then will shift gears.

Relevant for thought of the present invention, this can be good, and promptly the gear level signal changes analyzed processing at least, is used for the identification of shelves, and this information then can be used to distinguish the gearshift intention.

Method for supervising will record moment hang into shelves, at this moment, this information is used for determining comparison signal.

Provide a kind of method thus, this method can be with higher reliability and the speed identification user intention of roughly shifting gears, and needn't establish special sensor in addition.A kind of further automation moment transmiting system, the early stage information that need be intended to about gearshift roughly is so that in time separate power-transfer clutch.

Advantageously, gear level signal and comparison signal quilt be analyzing and processing like this: discern the intersection point of these signal curves, and the intention signal of then will shifting gears is defeated by clutch actuation system.If as long as two signal curves are explored or utilized, then no longer need the software or the hardware of consumes expensive on its intersection point for identification gearshift intention.

According to contriver's thought, this can be favourable, promptly in manual transmission, distinguishes the gear selecting stroke between the gearshift groove and is positioned at gearshift groove in-to-in gearshift stroke,, for determining the relevant position of gear level, can detect gearshift stroke and/or gear selecting stroke here.

The formation of comparing signal is not needed extra sensor yet, because each input parameter (drive torque) is obtained usually.Comparison signal is formed by filtering signal, and here, filtering signal is increased and/or reduces a steady state value and an offset signal; Thereby guaranteed to a great extent: have only when the gearshift intention in fact occurring, gear level signal and comparison signal just intersect.

Favourable continuation development is, if detect intersection point when two bars curves of analyzing and processing gear level signal and comparison signal, then detects the existence of gearshift intention, at this moment, verifies the gearshift intention by gearshift intention counting machine.By desired gearshift intention counting machine, can guarantee: identification and gearshift in the gearshift intention are intended to have certain time interval between the transmission of signal, test in this spacer segment; Whether in fact carried out shift process.Moment transmiting system thus will be effectively prevented the triggering of mistake.

The gear level signal will be to carry out filtering adjustable delay time for forming filtering signal.

Particularly advantageous is that the gear level signal can be to form filtering signal to handle with the PT1 characteristic.

Further advantageously, monitoring gear level signal; In confirmable test period, the variation of analyzing and processing gearshift stroke like this: under the situation that is lower than confirmable gearshift stroke change threshold, gearshift intention signal will send rearmounted device to respectively in the part scope of the regulation of gear level stroke while.

The gear level signal that being used for determining gearshift intention (it will continue to transmit) can be by indivedual adjustable filters (it can be regulated by filtering parameter) generally, and is tuning like this: that least identical moment transmiting system can be monitored with identical method.Advantageously, test period is definite like this: make it all the time significantly greater than inactive gear level half period of vibration and Oscillation Amplitude in the running of travelling.

Appropriate is, the part scope of the gear level stroke of regulation is positioned at outside such gear level stroke range, in described such gear level stroke range, and inactive gear level motion in the running of travelling.

For implementing to be necessary to ask for the aviation value about the gear level period of vibration according to method of the present invention, thus, the time length of test period can be asked for to come relatively and determine with the aviation value of gear level period of vibration.

Favourable continuation development can detect: gear level is whether free vibration or particularly have a vibration characteristic that changes relatively therewith by hand steered in the running of travelling; And the described aviation value that is used for determining test period length forms with this monitoring result and carries out relatively.

Adapt with another expansion of the present invention, favourable part is: measure the sense of motion of gear level, and when this sense of motion is reverse, send a control signal for gearshift intention counting machine, and/or regain a gearshift intention signal that may send.

Thus, the subsidiary sense of motion of observing gear level, and when this sense of motion is reverse, regain a gearshift intention signal that vibration provides according to gear level.

Further advantageously, the constant that forms comparison signal is by selecting with the dependence of the typical run Oscillation Amplitude of moment transmiting system inoperation gear level.

Also advantageously, form the oscillation frequency that is tuned to inactive gear level in the running of travelling delay time of filtering signal.

According to contriver's thought, the advantage that control method is had especially is that monitoring drives load; When surpassing a certain fixing driving load, introduce a control signal simultaneously to gearshift intention counting machine.Thereby can prevent when the moment of starting pusher side to exist raises that power-transfer clutch is undesirable unclamps or closed.Also advantageously, offset signal gets involved with the dependence with the throttle valve angle of the combustion engine of packing into as driver element and uses.

According to contriver's thought, appropriate is that each is detected the gearshift stroke of gear level or gear selecting stroke by a potentiometer.Also advantageously, the gearshift stroke of gear level and/or gear selecting stroke are controlled with such form and method by potential device: potential device can be discerned the position of shelves by this.

Yet, the method for being not only above-mentioned controlling torque transmission system that the present invention relates to, and comprise a kind of like this method of controlling torque transmission system: promptly with a kind of device convergence controlling torque transmission system; Moment transmiting system is provided with a driver element after in power stream, and in power stream, pre-set or after a speed ratio variset is set; The speed ratio variset is provided with one around device, and to second device transmitting torque, here, the outlet axle of second with the inlet axle of speed ratio variset device of first device and speed ratio variset is linked together effectively from first device for it; Be linked together rightly around installing to utilize to compress or strain with first and second device friction, and compressing or straining to control with the dependence of operation point around device, it is characterized in that: moment transmiting system carries out the convergence control that moment is followed the tracks of with a transferable torque, its size is determined in this torque like this in each operation point, what make the speed ratio variset does not enter slipping state around device.This means: moment transmiting system is controlled like this in the limit of skidding of each operation point: make around the device the limit of skidding remain bigger, and if the torque that applies is too high, then before skidding around device, moment transmiting system has begun to skid.

Further advantageously, around compaction degree and/or the degree of tension of device in each operation point, by and the engine moment that exists and/or the power established based on additional energy consumer and the extra margin of safety dependence between along separate routes determine and regulate, simultaneously, the transferable torque of moment transmiting system is by controlling with the relation of complying with of operation point; And, when it produces fluctuation, before reaching the limit of skidding, will cause skidding of moment transmiting system around device by the transferable torque of moment transmiting system.

Appropriate especially is that moment transmiting system is in the limit of skidding of each operation point, than the little or less ground convergence control around the limit of skidding of installing of speed ratio variset.

In addition, be according to the favourable part of thought of the present invention: the torque fluctuation and the torque shock ends of drive side and slave end are isolated and suppressed to moment transmiting system with its limit of skidding relevant with the operation point, and mainly can be protected by skidding around device.Prevented as above-mentioned situation around trackslipping of device, here, may cause around the damage of installing around trackslipping of device, and driving device is shut down.

Thought according to the contriver, appropriate is, compaction degree around device is controlled with the operation point with degree of tension relevantly, simultaneously, additionally the torque that exists is considered the reserve level of a safety, but this amount is controlled according to the convergence of moment transmiting system transmitting torque, but can make it the approaching and/or coupling with transmitting torque.The coupling of safe moment, can this form carry out in this case: being provided with of safe moment can get littler than prior art state design.

Particularly advantageous is that based on the compaction degree and the degree of tension of moment transmiting system slipping protection, dropping of its safe spare amount should be the least possible.

Suitable especially is that skidding or sliding will appear the short time when the torque spike in moment transmiting system.Thus, the torque shock ends of drive side or slave end might be isolated or inhibition or filtering, and this impact may occur in limit travel situations, and may damage or destroy around instrument.

What the present invention relates to is not only method described above, also relates to a kind of equipment, and as a kind of speed ratio variset that utilizes the control of said method convergence, this device can be a stepless adjustable driving device.Particularly advantageous is that this speed ratio variset is that a stepless adjustable conical disc is around driving device.Special preceence also is: the moment transmiting system as an equipment part is a friction clutch, or a tor-con bridging clutch, or a reversing clutch, or a safety clutch.Power-transfer clutch can be to do or wet running power-transfer clutch.In addition, this can be very appropriate, but promptly has the setting device of a convergence control transmitting torque, and it can be electric and/or hydraulic pressure and/or machinery and/or compressed-air control, or the manipulation of this setting device is carried out with the combination of these characteristics.

The present invention will be further described according to a configuration example in the vehicle technology.

The specific embodiment

Fig. 1 a and Fig. 1 b represent the scheme drawing of the part of a vehicular drive section.A drive torque is delivered to moment transmiting system 3 from the driving engine 1 that moment of inertia 2 is arranged herein.Can be passed to by these moment transmiting system 3 transferable torques on the back link of a driving device that is not described further for example, for example input block.

Fig. 1 a represents that one has the structural representation of power moment transmiting system 3 along separate routes.In this transmission system, for example-Fu Ting (Fottinger) coupler, or one turbine transformer 3a and a tor-con shunting coupler 3b in power stream, be in parallel, a control setup is such controlling torque transfer device 3 herein, making the minimum basically torque that exists in several operating ranges, is not only by turbine transformer 3a, is exactly by good fortune court of a feudal ruler power-transfer clutch, or only by tor-con bridging clutch 3b, or by two torque transmitter 3a, 3b transmission in parallel.

In a few thing scope, but on purpose the distribution of the carry-over moment between torque transmitter 3a, the 3b of parallel connection arrangement is to be worth expectation, and can correspondingly implement.The ratio of each carry-over moment, for example pass by conversion bridging clutch 36 and pass by turbine transformer 3a, can adapt to the particular requirement of each operating range.

Fig. 1 b represents the structural representation of no rate moment transmiting system 3 along separate routes.Inactivity such moment transmiting system 3 along separate routes can a kind of typically power-transfer clutch, as friction clutch and/or reversing clutch and/or starting clutch and/or safety clutch.Be arranged at the virtual power of following control program simulation along separate routes, correspondingly the controlling torque transmission system.

Fig. 1 a and Fig. 1 b (partly the driving Duan Youyi of Miao Shuing in driving Duan Liliu, arrange, with or without power moment transmiting system 3 along separate routes) scheme drawing and the frame circuit diagram example that may arrange or expand of only having described moment transmiting system.

In addition, the such arrangement of moment transmiting system also is possible: promptly the element of moment transmiting system decision driving device converter speed ratio before or after power stream can be arranged.For example can arrange a moment transmiting system (as coupler) in power stream before or after the change-speed box of stepless adjustable conical disc around driving device.

Similarly, a stepless adjustable drive is that a stepless adjustable conical disc can be by the moment transmiting system of a drive side and/or slave end arrangement around driving device.

Press the band power system along separate routes of Fig. 1 a, as turbine transformer 3a, band bridging clutch 3b, can enough control methods control in this wise or convergence control by invention, make that always transferable torque is controlled or convergence is controlled by each transmission system in parallel (as turbine transformer 3a, and/or bridging clutch 3b) in band power system along separate routes.Generally, control to torque transmitted convergence ground, and will adjust voluntarily by the transferable torque of moment transmiting system in parallel with it by one of two moment transmiting systems of arranging in parallel.

More than two (moment transmiting system of N transmission system in parallel, generally transferable basically moment are by (N-1) individual transmission system control or convergence control, but the adjusting automatically immediately of the transmitting torque of N transmission system.

To inactivity system along separate routes, as friction clutch, transferable torque comes convergence control in this wise by the control loop wire that is placed on below the control setup, and mat control setup simulation one has virtual power branch system.Use this control setup, but friction clutch 3c convergence controls to a rated value, it is less than 100% transferable torque.But Kong Zhi moment rated value poor to 100% whole transmitting torques controlled with the relevant safe moment 3d convergence that skids with control one like this.Like this, can reach: friction clutch and not higher thrust (with it according to required the comparing of moment to be passed) closed mutually.Secondly, because the mode of operation that skids has guaranteed inhibition torsion oscillations and torque peak in driving section, as torque shock ends.

This is advantageous at other mode of operations of moment transmiting system operating range, and moment transmiting system as power-transfer clutch or friction clutch, is crossed the control of compaction degree convergence with a low but careful regulation.In this operating range, for example under high rotating speed, raising skid and thus the consumption of fuel of combustion engine avoided.

When a compaction degree be about on average exist torque 110% the time, under the torque peak of short time, can produce suitable clutch fading or slip.So can carry out peak value in closed basically power-transfer clutch suppresses.

Only in low the crossing under the compaction degree of power-transfer clutch, the torque shock ends that further has a peak value is slided or is skidded by the short time of power-transfer clutch and is suppressed or isolates.

Between the system of moment transmiting system 3 transmission of torque of arranging in parallel, the flags parameters of torque distribution is the torque distribution COEFFICIENT K _MEK _MEBe with power-transfer clutch or other moment transmiting systems (for example tor-con bridging clutch) but but transmitting torque to the definition recently of the total carry-over moment of moment transmiting system.

The torque distribution COEFFICIENT K _MEIllustrate: but for example which kind of proportionate relationship the transferable torque of power-transfer clutch 3b is in to total transmitting torque.

Work as K _MEValue was less than 1 o'clock, and its meaning is: between parallel system 3a, 3b, distribute transferable torque, and by the 3a of each system, 3b torque transmitted less than the total torque that maybe will transmit that exists.

Work as K _ME=1, transferable torque is only transmitted by one of schedule system 3a in parallel, 3b, particularly by power-transfer clutch 3b.When the short time torque peak surpasses the value of transferable moment, slip power-transfer clutch or moment transmiting system just takes place or skid.In the operating range of no torque peak, total torque is by 3a, systems communicate of 3b.

Work as K _MEValue was greater than 1 o'clock, and similarly total exists torque by a systems communicate, and for example the compaction degree of power-transfer clutch is equivalent to a transferable torque again, and it is greater than the torque that exists.Thus, can therefrom leach little then not filtering of torque irregularity to the bigger torque irregularity that surpasses threshold values.

The compaction degree excessively of regulation is the reaction time weak point of system to another advantage of the clutch of complete closure, for example unclamps until power-transfer clutch.System needn't come loosen the clutch from complete engage position, and needs only the position from practical adjustments.Under same time length, can use slower slightly transmission device on the contrary.

Fig. 2 a to 2e represents the physical property of moment transmiting system or the characteristic and the torque distribution COEFFICIENT K of physical quantity _MEFunctional relation, a turbine transformer that has a tor-con bridging clutch for example.Ten and expression K on the ordinate _MECoefficient has positive or anti-influence to described physical property.

Fig. 2 a represents that automobile drives the acoustic efficiency that passes section.Wherein one is the curve that has the moment transmiting system of shock absorber, and another is the curve of the moment transmiting system of no shock absorber, all with K _MEBe abscissa.The moment transmiting system band and not with shock absorber with K _MEFor two curves of function are parallel.The moment transmiting system of band shock absorber compares with the moment transmiting system of no bumper, shows the quality that slightly improves at acoustic connection.K _MEValue demonstrates as function: K _ME=0, acoustic efficiency is assumed to its optimum value.Along with K _MERaise, acoustic efficiency descends monotonously, until a high K _MEDuring value, acoustic efficiency carries out the transition to one and K _MEIrrelevant fixed value.

Acoustic efficiency and torque distribution COEFFICIENT K _MEDependence relation can illustrate like this: strengthen to drive the decoupling of section, because the increase of skidding is played and reduced K from the torque spike of torque irregularity and actuating unit _METhe effect of value.

Along with reducing and K of skidding in the moment transmiting system _MEIncrease, drive torque irregularity in the section transmitted epistasis, cushioning effect reduces simultaneously until the specific K of one _MEValue, cushioning effect becomes very little or has not existed, produce thus one with the K that after this increases _MEValue is the acoustic performance of constant relation.The K of constant acoustic performance appears having with the torque distribution coefficient _MEValue has nothing to do with driving section characteristic at that time.This value is about K in the characteristic system _ME=2.When this was worth, the power-transfer clutch of moment transmiting system was closed into such degree, transmitted each torque fluctuation basically.

Fig. 2 b represent a band tor-con along separate routes the heat load of the turbine transformer of clutch to K _METhe function of value.As heat load, can typically be interpreted as the energy input in the system, or because friction, or because the velocity contrast of member.Extraordinary circumstances for example can think that energy inputs to tor-con, in other words detailed point, to the fluid of a tor-con.Equally, can understand the friction face that energy inputs to tor-con bridging clutch and/or friction clutch.

K _MENumerical value was little in=0 o'clock, along with K _METhe increase of value, heat load is risen.Because rotating speed is poor, the energy input is interpreted as the heat load of system.Along with K _MEIncrease, owing to the input of the speed discrepancy energy in the tor-con reduces, until K _ME=1, tor-con bridging clutch closure, speed discrepancy equals zero, and therefore supposes that heat load is its optimum value.Work as K _ME〉=1, heat load is a constant, and equals K _ME=1 value.

Fig. 2 c represents the variation of pulling force, K _MEIncrease, pulling force reduces, because little K _MEValue makes full use of the transformation range of tor-con, and/or little K _MEValue allows to reach optimal other the operation point of combustion engine.

Among Fig. 2 d with K _MEValue increases, and can identify more favourable consumption, by one reduce skid, for example in the scope of turbine transformer, because one with K _MEValue increases and the closed power-transfer clutch that increases and reduce consumption of fuel.

Fig. 2 e represents that load variations is as K _METhe functional relation of value.The load variations characteristic demonstrates, and works as K _MEJust under so closed power-transfer clutch, its transferable moment was equivalent to the moment that applies for the most suitable in=1 o'clock.

Fig. 3 represents the structural representation of the frame circuit diagram of a control method.At this figure middle regulator and control section integrating representation in square 4.Control method 5, adapter 6 (the adaptive and/or parameter adaptation of system) can be shown in the comprehensive square equally.

Control section band control setup or transfer unit band control setup 31 and the interference that system works is shown in the square 4.Actuating unit 16 as combustion engine or driving engine, makes engine moment M _Mot33 are free to arrange input parameter 14, as fuel charge, and load beam, the rotating speeds of actuating unit etc., or system parameter 32 are as temperature etc.This engine moment M _MotA part of 33 is by additional energy consumer, as flare-aircraft, interior environment system, and servopump, controlled complementary pumps etc. are shunted.The consideration of additional energy consumer is the net torque 36 that deduction shunting moment 34a obtains synthesizing from engine moment 33 in square 35.

For example owing to the moment of inertia of escapement, the dynam of driving engine 16 and/or driving section is considered in square 37.Dynam can be considered particularly the moment of inertia of member at that time, with of the effect of these moments of inertia to clean drive torque, dynam in view of system, moment Mdyn38 is proofreaied and correct in transfer device transmission by the band adjusting mechanism, continues to reach driving device or to the vehicle 39 of back connection from the actual moment 48 of power-transfer clutch here.

The transfer unit 31 that has setting device is subjected to the influence of parameter 40, as temperature, and the friction coefficient of friction lining and skid etc.In addition, transfer unit 31 is dispersed as driving engine 16, aging or from the influence of not directly measuring the interference that influence parameter etc. and/or interference, square 41 illustrates this influence.

Adaptive 6 are divided into three scopes basically, additional energy consumer or auxiliary unit 7 regard as one adaptive, to be applied to disturb adaptive with disturbing influence, so additional energy consumer can be conditioning unit, light machine, controlled complementary pump servopump and other to moment is distributed and moment shunting works additional energy consumer together with the adaptation strategies that exists and adaptation method.

The signal of additional energy consumer 7 and information 8 are adaptive as additional energy consumer 7, can determine and/or calculate additional energy consumer 7 situation at that time.Among other things, this situation is pointed out: additional energy consumer at that time is because of its connection or disconnect and shunt a moment, if it is connected, Shi Ke shunting moment was much at that time.

Very clear in Fig. 3, except that additional energy consumer 7, the adaptive first and second

adaptive loop wires

9,11 that are divided into of system.In the first adaptive loop wire 9, consider the influence of measurable interference parameter 10, in the second adaptive loop wire 11, only covered the influence of not directly measuring interference parameter or dispersing that comes according to direct measurable deviation and system status parameters 12.

Calibration and/or compensate for disturbances influence are made like this: be not to change the parameter that influences disturbance variable, simulate these interference parameters by virtual interference parameter exactly, and compensate according to virtual interference parameter.

In both cases, disturbance variable will be proofreaied and correct or compensate like this, makes interference effect or interference parameter cut off or be reduced to the degree of a permission.Though can not force to find the correct reason that produces interference by virtual interference parameter simulation interference parameter, but thus, interference parameter can produce the just influence on the above-mentioned meaning to the influence of total system.

In addition, expression one square scheme circuit in Fig. 3, and the mutual action that an any distance and a setting device are arranged with adaptive moment control device.Be system such as moment transmiting system, can be placed into or without the following moment control device of power shunt.

In adaptive square 7, produce the adaptive of additional energy consumer, as the drive torque M of driving engine supply _MotA part when being accepted by unit at that time, auxiliary unit, light machine for example, controllable pump or conditioning unit have shown the shunt of moment stream and/or power circuit.To power-transfer clutch convergence control, its meaning is: from a drive torque M _MotSet out, real moment can not be provided, that is to say from misdeeming to be the specified clutch torque of higher engine moment and too big with this adjustment data of trying to achieve.With the adaptive power that the is indicated identification along separate routes of additional energy consumer, can carry out so later on, make full use of corresponding subject signal or measurement parameter, as the keying of air-conditioning compressor, conditioning unit or other additional energy consumers.

Draw a correction of disturbing in the second adaptive square 9, this correction is caused by measurable parameter, and for example temperature-cooling water temperature is influential to engine moment, or revolution-friction coefficient can change owing to skidding.Later on these proofread and correct with adaptive 1 sign, in these cases, compensation and/or correction can produce like this, not to pass through parameter adaptation, for example in the compensation square 28 afterwards or in transmitting square 30 friction coefficient to the correction of temperature, be exactly that for example engine moment is to the gamma correction of temperature by adaptive with system theoretical or the interference model mode that experiment is set up.

Those are because immeasurable system input parameter and/or aging and/or disperse caused interference and can calibrate and/or compensate in the 3rd adaptive square 11.Because the pattern of disturbing, for example aging or disperse, not from direct measurable input parameter, can elicite, must react by observing system and discern.This means: this interference can not compensate before its effect in advance, but the system response conduct was observed and then proofreaied and correct and/or compensate departing from of desired characteristic.

These depart from or can directly record, and as with one by the torque sensor of power-transfer clutch, or calculate by other measurement parameters and get by means of a transaction module, under detection event, the reference performance diagram that needs are suitable or clearly, system reference parameter.In order to compensate this interference that has identified, and then to find out the local of interference source and proofreaied and correct, perhaps suppose a virtual interference source A or a B, found out correction for drift thereon.Equally, an interference is owing to an existing square, for example the inverse transfer function of driving engine square 13 or transfer unit (in transmitting square 30).

The ownership of this interference can be illusory, and this square is not to interfering the origin cause of formation to be responsible for.At this moment grasping state parameter should have nothing in common with each other, and adjusting is not for good and all, can reduce in the operating range of some appointment.

Do not having to use adaptation parameter under the situation of adapter, elicited under the former adaptive situation of this adaptation parameter.

According to Fig. 3 at the drive torque M that forms and calculate actuating unit 16 (for example combustion engine) from 13 li of the engine characteristics squares of different output parameters 14 _Mot15.

Here the parameter that runs into comprises two following parameters at least, i.e. the rotating speed of actuating unit, and the fuel pedal position of load beam position or fuel inlet, the low pressure in the suction system, injection time consumption of fuel etc., other aspects are forming or are calculating drive torque M _MotThe knowledge that processing in 15 o'clock obtains about possible interference effect (wearing and tearing, temperature) aspect.

Draw a connection in connecting square 17, owing to consider the additional energy consumer in adaptive square 7, this connection facilitates the correction of drive torque, this correction to finish with addition method, and the shunting moment of the additional energy consumer of seeking in 7 is by engine moment M _MotIn deduct.This proofreaies and correct engine moment and represents with MNetto18 below.

The engine moment of proofreading and correct for the shunting torque of additional energy consumer 18 is input parameters of square 19, and this square square by way of compensation works to interference parameter correction or compensation.Can simulate interference source by corresponding coefficient of correction or corrective action in compensation square 19, the interference parameter of interference source can be compared with the interference parameter of real appearance or is exactly.The interference parameter that actual capabilities exist is got back to adaptive square 2, and makes the deviation that occurs in system and/or fluctuation (because production tolerance, reasons such as pollution) to equaling desirable rated condition.

By function component and/or non-addition through the property component, multiply each other and proofread and correct, so just meaningful in general: interference effect is compensated, or interference effect can be reduced on the interior tolerance level of a receivable limit scope.So the addition of a virtual energy consumer form is disturbed and can be considered, and is superimposed upon on the drive torque, if disturb the physical cause that also has other.

In dynam square 20, all problems of the dynam of process to be controlled for example to the consideration of engine quality moment of inertia of motion, if this is beneficial to system performance or its control, can be controlled again.When forcing speed or postponing, improved the quality of convergence control like this.This dynamic (dynamical) drive torque 21 is labeled as M hereinafter _AN

In operation point characteristic square 22, determine specified clutch torque M _KsollWith the relation of operation point at that time.From moment M through kinetic proofreading _ANPercentum component and safe moment M _SicherThe specified clutch torque of middle calculating, safe moment is described in safety square 25.This percentum component in other characteristic curve squares 23 by the torque distribution COEFFICIENT K _MECome to determine, can change by other correction square 24 through the percentum component of the torque of kinetic proofreading.

To having real power system along separate routes, as the situation of the tor-con of band bridging clutch, the component of security function can be zero (M _Sicher=0), because when skidding, builds up a moment through tor-con.

Under inactivity total system situation along separate routes, must be by security function M _SicherGuarantee that for example additional moment is added on the existing moment under the situation of skidding, and has so just stoped and has built up the too high value of skidding.

In performance diagram square 23, can determine or obtain the concrete component coefficient K of operation point at that time _ME, this COEFFICIENT K _MEBe placed in or be stored in cooresponding family of characteristic curves or the characteristic curve, one or more following parameters such as engine speed, engine moment, moving velocity etc. enter characteristic curve.When two systems have a power shunt (has the tor-con of bridging clutch to form), this K _METhe ratio that coefficient is expressed transferable clutch torque and provided treating between the main shaft moment of domination to be regulated by control setup.

To inactivity system along separate routes, by component coefficient K _MEDetermine the immediate component of Torque Control.Other moments by in safety square 25, try to achieve with the relevant safe transmission of torque of skidding.

In proofreading and correct square 24, also have the kinetic proofreading and/or the compensation of a moment percentum component of trying to achieve in advance.This correction and/or compensation are carried out with the form of the rising limit of rated moment.Be masked as the gradient restriction below.

The gradient restriction is the form of the maximum permission increment in each scanning step for example, or is undertaken by the preset time characteristic.By this measure, the excitation that drives section is restricted on the yardstick that a maximum allows, people can obtain a good comfortable load and change characteristic thus.

In safety square 25, from operation point at that time, can obtain a safe moment M _SicherThis safe moment can be with calculating with the relation of the rotating speed that skids.In this case, rise the safe moment skid with skidding of rising and become big.Thus, inactivity system along separate routes, power-transfer clutch can be protected.Also have other or the like, by such security function, can stop or reduce the hot overload of transmission system at that time.In safety moment and the function dependence between skidding can describe or provide in advance with suitable function by characteristic curve or performance diagram.The output parameter 27 of the square of arranging above 26, the power-transfer clutch rated moment can be expressed as follows:

M _Ksoll=K _ME* M _AN+ M _SicherIn this formula, do not consider dynam square 24 herein.Considering under the situation of square 24, the power-transfer clutch rated moment with

M _Ksoll=f _Dyn(K _ME* M _AN)+M _SicherDescribe.F herein _Dyn(K _ME* M _AN) dynam that comprised in kinetic proofreading or the square 24 considers.

The power-transfer clutch rated moment is by the moment partition ratio K relevant with operation point 22 _MESize and safe moment M _Sicher25 size decides.

In other compensation square 28, the correction that produces a power-transfer clutch rated moment by second virtual interference source B.

In transmitting square 30, utilize the contrary propagation function of the transfer unit of setting device, the power-transfer clutch rated moment M of these corrections _Ksoll-korr29 are transformed to adjustment data, utilize this adjustment data convergence to control the transfer unit of this band setting device 31, and this transfer unit is realized cooresponding avidity.

The transfer unit with 31 signs for the band setting device can be regarded as: is with power another system along separate routes, as has the tor-con of bridging clutch, or the inactivity of power-transfer clutch form system along separate routes, as friction clutch.The middle device of using under the system situation of inactivity branch can be liquid clutch, dry type clutch, magnetic-powder clutch, reversing clutch and safety clutch etc.

The generation of operation setting device necessary energy/power is an electrical motor, hydraulic pressure, electric hydraulic, machinery, compressed-air controlled or other modes.

Fig. 4 represents to have the frame circuit diagram of adaptive control method.Control square 5 and each adaptation method of overlap joint have here been described.The square 4 (control travel of the band setting device among Fig. 3) that does not have statement in this figure, can be quoted from Fig. 3 as long as also be suitable for Fig. 4.

From performance diagram square 13, provide an engine moment 15, this moment and one is proofreaied and correct moment 42 and will be handled in this wise, deducts to proofread and correct moment 42 from engine moment 15.The shunt moment of 43 pairs of additional energy consumers 7 of difference moment is carried out additive corrections equally, is again that the moment of auxiliary unit at that time deducts from moment 43 according to its state here.

The torque of moment of so handling or auxiliary energy consumer and auxiliary unit can be tried to achieve from below or calculate: from the data or the signal of the operation point 22 of each unit, and/or from additional signal 44, for example connection and/or changing-over and/connect cut-off signal and representative type working signal, for example electric current one voltage signal of light machine.

Seek and be performed such, the representative type working signal takes out from performance diagram or characteristic curve, and the reception moment under the therefore additional energy consumer is by reading performance diagram or characteristic curve is tried to achieve.The one possible mode of seeking is storage equation or set of equations (signal parameter is imported as parameter), and separating of equation or set of equations determines to receive moment.

Correcting signal 45 can be because of dynam square 20 experience one kinetic proofreading.Dynam square 20 is considered the moment of inertia of rotational parts, and as engine part and moment of inertia inertia wheel and the moment of inertia that drives other parts of section, operation point 22 can be tried to achieve or calculate from the state parameter 40 of system.This can become possibility by trying to achieve data from performance diagram, or realizes by separating of equation or set of equations, and at this, state parameter enters in these equations as parameter.

From the operation point 22, for example from performance diagram, try to achieve moment partition ratio K _ME23.Signal 46 through kinetic proofreading multiplies each other with moment partition ratio 23, and determine a moment with this, it is to be transmitted by (turbine transformer of band tor-con bridging clutch) tor-con bridging clutch, and this signal can be proofreaied and correct by means of dynam square 24 once more.

In the example that Fig. 4 represents, it is that the maximum rising limit of moment realizes that dynam square 24 is taken as gradient restriction.The restriction of this gradient can realize in this wise, and the function that moment rose as the time compares with a maximum permissible value (a for example inclined-plane) in a set time scope, and when rising the maxim that surpasses the inclined-plane actually, with the inclined-plane signal as actual value.

Possible the performance of another gradient restriction realizes that by dynamic (dynamical) filter the time response of filter can differently be selected by the operation point, makes that when use one PT1 filter time constant is adjustable as the function of operation point.

The output signal 47 of output square 24, power-transfer clutch rated moment M _KsollAs press Fig. 3 and continue to transmit to the transfer unit of band setting device.The actual moment MKist48 of power-transfer clutch at this power-transfer clutch rated moment and coupled position 49 places compares, and this is relatively guaranteed that by an addition program method is to deduct the actual moment of power-transfer clutch from the power-transfer clutch rated moment, gets a difference DELTA M50.Difference moment Δ M is processed into one and proofreaies and correct moment 42 in the rank rear square of frame circuit diagram.Proofreading and correct moment handles with engine moment at coupled position 52 places.

The adaptive location that is not directed at interference parameter in the example of Fig. 4, get back to virtual interference parameter or disturb but interference led, during with virtual interference parameter, the correction of true interference parameter and/or compensation no longer require real error reason and wrong location and corresponding the correction.In the example that Fig. 4 represents engine moment or motor characteristic curve figure are taken as virtual interference source, such mistake that occurs and interference mean the interference of engine moment, and proofread and correct moment M by a driving engine _MotKorrProofreaied and correct or compensated.

Adaptive purpose is to realize moment partition ratio K _MEPrecise adjustment as far as possible so that interference is made optimum response and is made the physical property optimization of system.

The way that utilization is found the solution equation or set of equations or use correction characteristic curve figure and can try to achieve correction parameter M _MotKorrCan be correction characteristic curve figure like this: be put in two taperings proofreading and correct parameter.When asking correction graph, propose to use same dimension and make motor characteristic curve figure, as energy consumption and engine speed.A dimension as correction characteristic curve figure also can be used a parameter, and a dependence of this parameter reflection one stroke transfer function is turbine speeds for example.

Make a correction characteristic curve figure and can realize that can determine a plane by three resting points, the function of correction characteristic curve figure as two dimensions determined on this plane by determining three resting points about engine moment and engine speed.Another possibility is: select four resting points, four resting points define a plane, this face decision correction characteristic curve figure.Square 51 weighting of carrying out resting points is as the function of operation point at that time in this article.Carry out the resting point weighting, because the deduction about compensation value can be made, as what make from each operation point in the plane of process correction characteristic curve figure on other operation point.Because can cause mistake like this, the deduction in the part scope of correction characteristic curve figure can not refer to other part scopes linearly, so introduce the weighting of resting point.

The result of weighting is: according to the difference of operation point or operation point scope, come the weighting resting point, the influence of point far away from the operation point in correction characteristic curve figure like this has less or bigger meaning.Square 53 is drawn the weighting of resting point, the adaptive time response of this square influence.Square 54 expression correction characteristic curve figure squares, this square 22 are tried to achieve motor torque compensation value 42 from the operation point, and this value is handled at point of connection 52 and moment 15.

Fig. 5 a to 5c has simply represented the interference and the time relation of engine moment, rated moment is with horizon in Fig. 5 a, with actual moment representing that with the horizon of a step this step can be defined as the additional components of engine moment, this component results from attached unit.Producing a step in the actual moment is being switched on or switched off or changing-over owing to attached unit in other operating ranges.

Be enhanced or reduce according to shunt power, this step can improve or reduce actual moment.Just may make following deduction according to shoulder height and time response: which attached unit should be connected, turn off or changing-over.

Fig. 5 b represents that rated moment comparing different operating ranges with actual moment with Fig. 5 a.The difference of this two curve can be differentiated interference parameter, the multiplication component of this parameter influence clutch torque.Therefore the compensation of this interference parameter and/or correction have the multiplication characteristic.

Fig. 5 c represents rated moment and actual moment once more, and two moments are separated from each other by additional components herein.Proofread and correct and/or compensate this interference and can be undertaken by the additional components of clutch torque.Change the example that comes among the key drawing 5b by friction coefficient, come example among the key drawing 5c by the deviation of adjustment data.

Proofreading and correct performance diagram in Fig. 6 is so to express, and driving engine is proofreaied and correct the function that moment is expressed as engine moment and engine speed.Particularly use four interior angle points of number range as resting point 55.The resting point weighting of Fig. 4 square 51 obtains like this, and resting point can change like this in its upright position in the operation point of appointment, is bearing higher weighting near the scope of operation point.This weighting can form by the operation point situation like this by the change of the upright position of resting point, makes 1 to 4 resting point bear this variation.

Determine to constitute the also conversion in this wise of four resting points 55 on a plane, from six resting points 55, see Fig. 6 a, often 3 resting points are set along an axle, by two faces that 4 resting points are respectively arranged of six resting point regulations, require two resting points in addition from two faces.

Show feature with another kind of form, utilize four faces of 9 resting point regulations, see Fig. 6 b.Set up performance diagram like this, promptly connect per two resting points adjacent, that belong to a face with a straight line, thereby, the frame of the such face in specialized range is made of 4 straight lines, and characteristic curve shows as a polygon in the face of the projection of specialized range, particularly on-right angle or non-square.Link line between two boundary straight lines that stack mutually of performance diagram also is the straight line intercept, and this boundary straight line is in a plane, and this plane parallel is in the plane that a scope axle of being stipulated by the sideline and the performance diagram of performance diagram is determined.

Another form of Fig. 6 performance diagram is represented a plane of bending, and this curved surface forms by a functional relation in three dimensional space, for example the parabola of second order.The face of characterization diagram of curves can be a plane of bending, and it is by resting point and/or functional relation and an equation or the set of equations decision of appointment.

Fig. 7 represents the frame circuit diagram or the diagram of circuit of the adaptive moment control device of a band moment transmiting system, below further explain this figure.This moment transmiting system can be: a power-transfer clutch for example, as the starting clutch of a friction clutch and/or an automatic transmission with hydraulic torque converter, and/or a stepless adjustable conical disc is around the tool for transmitting of driving device and/or the power of surging tor-con and/or a reversing clutch and/or the safety clutch of band tor-con bridging clutch.The operation transmission of torque parts can carry out like this: by an electric apparatus, electric hydraulically operated and/or mechatronic and/or a machinery and/or surge a power and/or a compressed-air controlled setting device.

Calculate the drive torque, particularly combustion engine of actuating unit 61 from different input parameter 60 according to Fig. 7.The parameter that for this reason relates to comprises two following parameters at least, as the fuel pedal position of the rotating speed of actuating unit, load beam position or input fuel, suction system negative pressure, injection time, consumption of fuel etc.Actuating unit is shown in the square 61, and the drive torque of actuating unit is represented with 62.The connection of working is proofreaied and correct in square 63 representatives to drive torque.Use the corrective system of supplying with by system adaptive 64 to proofread and correct.This system adaptive 64 can be used as program module and uses, because input parameter 65, the parameter of analyzing ground or the parameter of digitally determining and coming from performance diagram, this module are got a medium drive torque earlier and proofreaied and correct.This coefficient of correction can be done balance to the deviation that occurs to wishing state in system, promptly by nonlinear component additionally or these deviations of multiplication ground compensation.

Square 66 representatives are to the moment partition ratio K of mode of operation correction at that time _MEDetermine or try to achieve or calculate that this moment partition ratio is generally between 0 and 2.But needs also can occur and use big K _METhe state of the system of coefficient.This K _MECoefficient is expressed by control torque ratio M clutch to be adjusted: M driving-correction is as a preset value, and this value is each operation point (pressing the kind of performance diagram).Preestablished by the selected weighting of criterion of quoting, just: in a performance diagram, make K for each mode of operation at Fig. 2 _MECoefficient.

K in total work scope _MECoefficient also may be a constant, and an equation or a set of equations are found the solution to determine or calculating K _MECoefficient, these equations or solution of equations have just determined K like this _MECoefficient.

At K _MEIn the coefficient feature diagram of curves or at decision K _METhe setting of the torsional damper that can realize or consider the state parameter of vehicle in the analysis equation of coefficient and roughly exist., may have the setting of bumper herein, for example a bridging clutch has special meaning, because K when having such bumper _MECoefficient can remain unchanged on major part in the operating range of tor-con combustion engine or that surge power at least in proportion.

A K who in wide operating range, remains unchanged _MECoefficient also can be realized power-transfer clutch such as friction clutch or starting clutch.

By moment partition ratio K _MECoefficient can be determined the ratio of clutch torque and drive torque.For example an operation of skidding with Torque Control is possible thus.With a power along separate routes the system of the tor-con of bridging clutch (for example with) can determine the moment components that should transmit by bridging clutch by this coefficient.In inactivity system along separate routes, as clutch system, under a stable operation, transmit and be not less than the moment that 100% drive side exists, coefficient will determine which component directly transmits by moment control device in the case.All the other power components are by controlling the similar characteristic of this moment simulation tor-con again with the relevant safe moment of skidding.At 67 usefulness K at that time _MECoefficient calculate specified clutch torque and actuating unit correction drive torque.68 around synthetic by system adapter 64, additional multiplication and/or non-linear component carry out other corrections of specified clutch torque.Here set in advance and connect 68.Can obtain a calibrated specified clutch torque thus.For many applicable cases, have only in two connections one just enough, at this moment should pay the utmost attention to and keep to connect 63.

Carry out from the calculating of stroke against the adjustment data of the calibrated specified clutch torque of propagation function 69, bridging clutch or power-transfer clutch are represented in this contrary propagation function.The contrary propagation function of square 70 expression setting devices.This function needs when being calculated as setting device 71 necessary adjustments data.Adjustment data is exchanged full line journey 72 and is worked, and it works to vehicle 73 again.The parameter of being adjusted by setting device can feed back on the control instrument, to improve the control quality of control method.For example be related to the position that the hydraulic efficiency pressure system of being adjusted by the electrical motor of electric hydraulic setting device sends cylinder.This feedback occurs in square 74 and 75.Square 76 expressions one computer device, it simulates the pattern of a vehicle and torque one direction of transfer.

On behalf of the observed reading of vehicle-state majority, square 77 send, and this value is handled as input parameter by square 78 in other place.

Dotted line among Fig. 7 is illustrated in the transition range between central computer or control setup and the vehicle.Can calculate the adjuster output parameter 70, this parameter can form on by the basis of 69 adjustments data of trying to achieve and on the basis of the contrary propagation function of setting device.Superior especially mode is that this setting device can be made up of setting device electric hydraulic or electric apparatus.Advantageous mode is application percentage valve or pulse width modulated valve.

75, can carry out the feedback of adjustment data with an adjustment joint or adaptive mode.Yet this feedback also shouldn't.Can measure actual clutch moment 79, as passing through torque sensor or strain gage (DMS).

Replacement is carried out the measurement of actual clutch moment 79, can carry out Calculating Torque during Rotary from state parameter and from vehicle physical and tor-con physics.For this reason message handler or in central processor to motor characteristic curve figure and/or tor-con performance diagram or represent the parameter of these performance diagrams to handle, and/or be stored in the memory device.Performance diagram or these representation parameters that the transmission of torque capacity of tor-con bridging clutch for example further can stored is represented.

Not only 76 can try to achieve actual clutch moment according to point 79 and point, also can to the actual clutch moment of measuring use by model calculate actual clutch moment compensate.Compensation is for example carried out according to min max principle or reasonable comparison method as the contact of logic.Is comparison below the system of mark can take place in adaptive in addition at Fig. 7 with 64, and proofreaies and correct accordingly.

A: the specified clutch torque of correction and the comparison of actual clutch moment, this here comparison can be carried out for a long time, for example by observing departing from the synchronous time window.The drive torque of proofreading and correct and the drive torque of inverse can form comparison, and this can carry out for a long time here, for example by observing the deviation of window synchronization time.Can make full use of subject signal equally, as being switched on or switched off of attached unit, as conditioning unit, compressor and driving device gearshift etc.

B: survey the system deviation in A, try to achieve, this deviation be additional multiplication and/or M drives and the nonlinear component of M power-transfer clutch in and in corresponding

adaptive loop wire

80 and 81 or connecting in the distribution of synthesizing thus in 63 and 68.

Survey and try to achieve the respective component of M driving and/or M power-transfer clutch by three charts of Fig. 5 a to 5c.

Fig. 7 represents to have the procedure chart of the control method of each method step.The first step is determined the drive torque of a driving engine from many input parameters, then proofread and correct this value for the first time by the adaptive predetermined value of system.This system is adaptive to be a program schema, by additional input parameter, analyze the parameter of determining and get a medium drive torque by the performance diagram decision and proofread and correct.The drive torque of proofreading and correct in the additive method step is with a component coefficient K _MEMultiply each other (it is between 0 to 2).This component coefficient K _MECan from the performance diagram of each mode of operation, extract.The setting of the torsional damper that in this performance diagram, can extract the state parameter of vehicle and roughly exist.By this component coefficient K _METhe ratio of decision clutch torque and drive torque.For example the in check operation of skidding is possible thus.

System's (tor-con of band bridging clutch) along separate routes determines moment components by this coefficient for band power, and this component should be transmitted by bridging clutch.In inactivity system's (tor-con that clutch system does not have and connects) lining along separate routes, in stable operation, transmit and be not less than 100% moment in the drive side existence.Coefficient will be determined in the case: which component directly transmits by moment control device.All the other moment components are controlled with the relevant safe moment of skidding by one again, this safe moment simulation one and characteristic like the converter phase.

This specified clutch torque that obtains is proofreaied and correct by the adaptive standard of system in next method step again.Can obtain the specified clutch torque of calibrated mistake like this, follow in the specified clutch torque of from then on proofreading and correct and seek adjustment data by means of the contrary propagation function of control travel.Use the contrary propagation function of setting device, in parameter that the controller mouth relates to will be from these adjustments data.Output parameter is passed on to setting device, and this setting device acts on control travel and vehicle at its this respect.Parameter by the setting device adjustment can be instead to adjusting instrument to improve the adjustment quality of method of adjustment.The position of the transmission cylinder that typically can adjust with electrical motor is relevant thus.From the other system parameter of this point, for example travel of clutch or vehicle parameter can transfer to controller.So these additional input parameters are crossed the adaptive inlet that finds described control method of system.

Fig. 8 represents adaptive naive model, and this adaptive restriction that is subjected to the additive correction of drive torque is adaptive by virtual interference source from the deviation that the difference of specified and actual clutch moment is synthetic.Fig. 8 represents actuating unit with square 61, as producing the combustion engine of engine moment 62.Square 90 representatives are adaptive by means of virtual interference source, and its output signal is handled with engine moment 62 with append mode at connection square 91.Because the moment of inertia of escapement, the engine moment of correction is proofreaied and correct with kinetic proofreading's method in square 2.

For example the moment that occurs on the tor-con of band bridging clutch power-transfer clutch is divided into two parts by means of the moment partition ratio, at this moment a part is transmitted by bridging clutch power-transfer clutch 36, and the difference of the moment that occurs and the moment of bridging clutch clutch transmits is then transmitted by tor-con 3a.

Figure 9 shows that a block scheme or a diagram of circuit, represent stall spot between center calculation device unit and the vehicle at the dotted line of figure lower part to the moment transmiting system control method.Block scheme shown in Fig. 9 is represented a simple adaptive device that constitutes.At this moment the control of bridging clutch power-transfer clutch is finished with electric hydaulic by an apportioning valve or a pulse expansion modulation valve.Regulating output signal calculator and the calculator output data is a levelling electric current, the contiguous percent make of output levelling that this electric current is modulated with the pulse expansion that is proportional to calculator.Clutch torque is synthetic by two partial pressure differences, and that promptly in this way controls is synthetic at difference of pressure on the tor-con bridging clutch and the difference of pressure between two pressure chambers of bridging clutch power-transfer clutch.The adaptive adaptive correction that is only limited to drive torque of system, its error is caused by the difference that the volume visitor decides moment and actual moment.

Version according to Fig. 9 contrasts the drive torque (M that Fig. 7 has left out connecting device 68 and proofreaied and correct _ANkorr) feedback.In Fig. 9 100 on recorded specified-difference of pressure DPsol1, and as the function of specified-clutch torque and as principal parameter, and with it with the drive torque M that has proofreaied and correct _ANkorrWith the variation of turbine speeds N-turbo-machine as the parameter that changes.

In Fig. 9, be divided into two branch function block 101a and 101b by next step function block 101 of Fig. 7 function block 70.Break-in power-transfer clutch 102a and 102b always come together accordingly with minute function block 101a and 101b.The input data of the contrary propagation function of control apparatus (101=101a and 101b) are the rated pressures of calculating in square 100 poor (DPsoll).Output data by affiliated pulse duty factor as the levelling output data.

After the control apparatus that connects be divided into two parts, electrical adjustment devices partial sum another part that a part is made up of a final stage and the valve coil of wire increases the hydraulic regulating device part that plays a decisive role, square 103 to a tor-con bridging clutch power-transfer clutch relevant pressure.The input data of electrical adjustment devices part are pulse duty factors.It converts a current value actual value on one side of output.Partly adjust corresponding tor-con bridging clutch shock pressure according to this actual current value (I-Ist) hydraulic regulating device.This is finished by the relevant pressure difference between tor-con bridging clutch clutch pressure chamber.

Square 101a represents the reverse function of hydraulic regulating device part, the rated current under calculating from rated pressure this moment.This part of control apparatus has an actual pressure feedback that records with pressure adaptive (102a represents by square) form.This pressure adaptive device 102a provides and proofreaies and correct good rated current.The second portion 101b of the back transfer function 101 of control apparatus represents electric part, the pulse duty factor under calculating from the rated current of proofreading and correct.Use the PID-adjustment algorithm for this reason.At this moment from adjusting deviation I _Soll-korr=-I _Ist(I _IstBehind the valve coil of wire, record) with a PID-regulating control electrical adjustment devices backward transfer character is partly calculated its input data I _Soll-R

The sequence number of selected each square is corresponding with the sequence number of each square among Fig. 7 in Fig. 9.In this way press among Fig. 9 just can be relevant with each function block of electric hydaulic structure with the function block of the general structure of Fig. 7.

All symbols in Fig. 9 have following meaning:

The rated pressure of DPsoll=110=on blocking device and tor-con bridging clutch is poor.Be equivalent to have between the cavity of piston both sides, place the difference of pressure of pressure.

Actual pressure in two cavitys of DPIst=111=tor-con bridging clutch is poor

The pressure of PNach=blocking device and tor-con bridging clutch back.

The rated current of Isoll=113=electro hydraulic valve.

Speed discrepancy between Δ N=114=pump impeller and the turbine wheel, promptly

Δ N=N pump impeller-N turbine wheel.

In Fig. 9, be marked with in 76 the shown vehicle status data 115 in square front and comprised skidding in bridging clutch power-transfer clutch and the tor-con.

Carry out among Fig. 9 one the step illustrate, rotation speed difference deltan N=N pump impeller-N turbine wheel does not have the adjustment data, and is the same with the known adjustment situation of skidding.Torque Control according to the present invention use this Δ N speed discrepancy as the status data of need command range in order to observe the moment deviation that may occur, this deviation is proofreaied and correct control by corresponding connecting device backspace in adaptive device then.In order to survey the deviation part on power-transfer clutch and the driving engine, can for example make the moment values of observing the storage of certain hour process by a kind of online time window mode.This finishes in being marked with system's adaptive device of 116.

By control of the present invention further advantage is arranged: even the drive torque interference sections is adaptive when blocking device and tor-con bridging clutch are decontroled fully, promptly at K _MEAlso can carry out in=0 o'clock.Make comparisons for this specified drive torque and the moment that acts on tor-con, this finishes at the connecting device 63 of Fig. 7 and with the method step 63 of Fig. 7 and Fig. 9.The deviation of the drive torque that may occur on the bridging clutch power-transfer clutch of connecting after can grasping in advance by this adaptive device can take under the situation that the bridging clutch power-transfer clutch is decontroled in advance.In system's adaptive device 116 and 64, try to achieve the moment that acts on the tor-con for this reason, be preferably on the tor-con performance diagram on this system's adaptive device for this reason and detect and store.The moment of trying to achieve appearance thus by the turbine wheel asked and the rotating speed difference between pump impeller.Then the nominal drive moment of this tor-con moment and actuating unit is made comparisons.Read to know, and that according to the status data that is measured particularly such as engine speed, load bar position consumes the stable motor characteristic curve figure that this drive torque can provide from the square 61 by Fig. 7 and 9, straying quatity and spray into time or the like and draw.Speed discrepancy between turbine wheel and pump impeller can be tried to achieve in square 76.

In addition, when square 76 internal memories contain the tor-con performance diagram, can also in square 76, try to achieve the moment of tor-con.

Figure 10 illustrates the vehicle 201 of band combustion engine 202 (for example with an explosive motor), and driving engine affacts on the transmission device 204 through power-transfer clutch 203 an electronic adjustment and that adjust by wearing and tearing.Transmission device 204 connects by an axle drive shaft 205 and a transmission shaft 206.On self-align and the power-transfer clutch 203 adjusted by wearing and tearing, be differentiated near the drive side 207 of explosive motor 202 with towards the driven one side 208 of transmission device 204.In the applying of power-transfer clutch 202 and disengagement system, be equipped with one and receive cylinder 2006, be connected with a transmission cylinder 211 by a conduit under fluid pressure 209.Fit with the disengagement system as the plain bearing of machinery, can determine the impulsive force of power-transfer clutch dish type spring with the way of contact of the cup spring tongue of cup spring facing to pressing plate, this power is impacted on the pressing plate of driving engine one edge direction, thereby impacts on the friction layer between pressing plate and escapement.Conduit under fluid pressure 209 sends cylinder 211 by one and is connected with an electrical motor 212, and at this moment electrical motor 212 and transmission cylinder 211 are contained in the casing together, are merged into a control apparatus 213.In same casing, on transmission cylinder 211, directly settle a clutch stroke sensor 214.Drawing thus has in control apparatus casing inside that unillustrated controller places on the printed circuit board (PCB) 227 on the figure.It also is the control electronics package that this brain box has a drive electronic device, so in a complete set of casing that is placed in control apparatus 213.

Controller is to be assembled with damper sensor 215, one engine speed sensors 216 and a tachogen 217 that is contained in transmission shaft 206 that can directly be contained on the explosive motor 202.Drawing vehicle 201 thus has a gear level 218, affacts on the power-transfer clutch by a gearshift link rod.One gearshift stroke sensor 219 is arranged on gear level 218, and this same and controller has signal contact.

Controller sends the adjusting data according to institute's bonded assembly sensor (214,215,216,217,219) to electrical motor.In controller, be provided with one or as hardware or as the control program of software for this reason.Instruction affacts self-regulating power-transfer clutch 203 by hydraulic efficiency pressure system (209,210,211) to electrical motor 212 according to controller.The function of this power-transfer clutch is at publication document DE-OS-4239291, DE-OS4306505, and DE-OS4239289 and DE-OS4322677 had described in detail.The content of these files offers some clarification at this, is to belong in the scope of Invention Announce.The advantage of automatically regulating power-transfer clutch 3 is to make reducing significantly of the conventional power-transfer clutch of the required force rate of clutch operating, and as the result who regulates manufacture method by wearing and tearing.Therefore electrical motor 212 can be determined oad with less power consumption and power reduction, thus control apparatus 213 total do compactness.It is that not to scale (NTS) is drawn that control apparatus 213 is compared with other parts of vehicle 201 in Figure 10.

According to Figure 11 a, 11b and 12a, 12b is explained in more detail control apparatus 213.Electrical motor 212, particularly DC motor are received on the scroll bar by a motor reel 220, and this scroll bar is engaged on the sectional wheel 222.On sectional wheel 222, fixing a bent axle, be connected with cylinder piston 225 actvies that send cylinder 211 by a piston rod 224.For the heat affecting of balanced hydraulic system liquid, air-breathing 250 of a band suction hole 251 arranged on the transmission cylinder.

Electrical motor 212 as DC motor, by the transmission device that can check automatically, sends cylinder 211 with pulling force or compression shock.This power is delivered to power-transfer clutch through conduit under fluid pressure 209.Control clutch 203 is fitted or is thrown off thus.

The axle that sends cylinder 211 is positioned on the different planes with engine shaft 220, and regulating mechanism 213 desired positions can be smaller thus.

At cylinder piston 225 inner or send cylinder shell 211 inside be equipped with one with the concentric assist spring 226 of transmission cylinder axle, this spring 226 is supporting motivation 212 when throw-out-of clutch, and spring 226 is overcoming under the effect of its elastic force and tightening when the power-transfer clutch attracting process.

The concerted action of electrical motor 212 and spring 226 will make an explanation at the curve shown in Figure 13.The change curve of power always is drawn on the travel of clutch curve.Solid line 237 is represented power-transfer clutchs when disengagement or attracting process, the power change procedure that electrical motor 212 applies.At this moment, the top separated time is represented the change procedure of power when disconnecting process, and the change procedure of bottom separated time power when representing attracting process.The power of the power that this power change curve is represented the disconnecting process needs during greater than attracting process.The spring characteristic curve of intermittent line 239 expression assist springs 226.Dotted line 238 expression spring 226 and electrical motor 212 synergistic power change curves.

Total power 238 that requires to apply from electrical motor 212 has obviously reduced.The force curve of dotted line picture moves to the direction of less power as shown, by selecting the supporting role of suitable assist spring 226 for use, make the characteristic curve of electrical motor and cup spring shift to the negative direction of power, from Figure 13, can see dotted line positive dirction with in the amount of the maximum of negative direction near identical.Because the supporting role of this assist spring 226 makes the oad of electrical motor 212 and does not compare littler with the oad of assist spring 226.Its prerequisite of method that supports with this assist spring is, electrical motor draw and be same the use in the direction of pressing.

Assist spring 226 places in mobile's shell in Figure 12 a, at this moment be put in two and settle scope 227a, between the 227b, settle scope 227a under the spring tension to one and piston rod bonded assembly tension washer apply impact, place scope 227b and then be supported in the scope of mobile's shell.In order to prevent that transmission device from making dirty, be built-in with a rubber diaphragm 229 at rest area 227a.Shell also has a deflation hole 230 in addition, makes hydraulic efficiency pressure system spill liquid and discharges.

Be arranged at the Torque Control action principle of the interior control program of controller,, simply be shown among Figure 14 as friction clutch to moment transmiting system.Control method is as one the 8 bit processing machine stored of software program at for example controller.Can control example such as electrical motor 212 with this control method.

Can record the drive torque M of driving engine 202 by damper sensor 215 and engine speed sensor 216 _Mot, and supply with control program as the input data and use.Engine speed sensor 216 is grasped engine speed N1, the rotating speed of tachogen 217 record transmission shafts 206, and this is to give control program as additional input data transmission.Calculate transmission device input speed n2 with the revolution counter of transmission shaft 206, in rotation speed n 1, the difference between the n2 then is masked as the rotating speed that skids, and the rotating speed that skids is determined by analysis in control program, and monitored that it does not surpass the limit of skidding.Surpass when skidding limit and then record as skidding the S stage, this stage S that skids is held until till being lower than when skidding limit again.

Clutch torque Mk proofreaies and correct data M with one _KorrPress following formula

Mk=M _Mot-M _KorrCalculate.Proofread and correct data M _KorrBe a moment values, improve, in the time of detecting as the stage S that skids, reduce by the control program process with the calculator pulse increment.By this method power-transfer clutch 203 is always moved back and forth round slip limit R.Slip limit R is time point, this time engine speed N1 begin to surpass transmission device input speed N2.This just in time is this situation, and the moment of promptly working as the appearance of driving one side is greater than the time from the instantaneous transferable clutch torque of power-transfer clutch.This kind method also has effect when not being constant when drive torque.

, before continuing to be delivered to control apparatus, the levelling data particularly to be put in order at the diagram of curves shown in Figure 15 a moment transmiting system such as friction clutch.

On abscissa the control apparatus specified value that can possess, the i.e. scope of the clutch torque that can transmit.This scope is subdivided into the part scope 240 that oblique line is represented of drawing again.Transferable clutch torque on the scope shown in this 240 about 100 and 140Nm between.The transferable clutch torque of calculating by control method needs only in this part scope, then has a 140Nm permissible value to be transferred to control apparatus.When other part scope 240, then similarly handle.

By the method the number of times of control apparatus adjusting motion is reduced.Adjusting motion, (promptly from a step to another step) determined on certain data.Can carry out like this about the characteristic design of adjusting motion, promptly the quantity of square or scope 240 is relevant and different with condition of service, and this measure has improved total life expectation and reduced the energy requirement of the actuating unit of torque-transmission system.

Figure 15 a to 15e is depicted as the control apparatus specified value that a specified clutch torque of confession of being undertaken by control method is used.

Because the automation of clutch operating needs a mobile, it can be transformed in relieving or closing course and the running power-transfer clutch by control signal and goes.The adaptive control of mobile's control method can be followed the tracks of with a moment and realize.Use moment to follow the tracks of following advantage can be arranged, promptly regulating control is not just decontroled and closing course when gearshift and igniting, but align like this at the whole when operation power-transfer clutch compaction degree of travelling, the clutch torque that can the transmit specified clutch torque with synthetic from motoring condition and operation point at any time is suitable, produces corresponding required pressurization or decompression after making comparisons with clutch torque again.The result who obtains is for holdback clutch, do not need during the regulating control shift process from the whole setting range of position process that touch fully, because follow the tracks of according to moment, the rated moment with concrete levelling adds a required corresponding adjusting position of equilibrium value and has aligned.Therefore to the dynamic relationship of system, particularly the relevant requirement of mobile can reduce by the governing speed of maximum, because only need overcome usually and through short adjustment travel.

Carry out a kind of this class design-calculated dynamic force moment follow the tracks of the mobile that must make charged motivation at whole service time and running time all in work, so that can carry out instantaneous surely adjusting again by the dynamic change of actual moment.

To the control method that guarantees that all the time moment is followed the tracks of, but must for example make an electrical motor often follow the tracks of the variation of carry-over moment.The possibility that driving engine is only used when needed can be carried out the tracking of clutch torque, to realize by level or by shelves.

Control method must guarantee to regulate all the time, can pass through the certain specified clutch torque of clutch transmits on each time gap.Clutch torque is followed the tracks of the influence that plays this respect, that is: making has a little overvoltage Δ m to allow to this means in certain error limit in certain divergent belt, and like this then operation that follow the tracks of reduces, and the load of control apparatus is reduced.The curve 241 of Figure 15 a has been represented the specified clutch torque calculated, and at this moment function 242 is equivalent to specified clutch torque and adds a divergent belt.The value of divergent belt 242 draws from shoulder height Δ m and its condition, and promptly Tiao Zheng clutch torque must not be lower than the clutch torque of calculating, and if variable quantity when surpassing a limit, only realize the variable quantity of the clutch torque of aligning.

Figure 15 b is depicted as the example by the serviceability of control method, above the specified power-transfer clutch of handlebar be transferred to the situation of limit more than 243, the specified clutch torque that is lower than limit is slightly adopted one, and to compare with limit can be identical or different values.By determining divergent belt and, the phenomenon of certain overvoltage taking place in several ranges of operation, cause that thus the activity of regulating control reduces immediately, and the regulating control load is reduced equally near control.Press the method shown in Figure 15 b, in specified clutch torque hour, regulate minimum clutch torque, the regulating control action that load links with control system can be reduced.Minimum clutch torque 243 for example can be relevant with the operation point, such as with conversion, with gear, with engine speed, with accelerator pedal position or relevant with speed-slackening signal.Figure 15 c shows the functional relation of minimum clutch torque with changing operate-point, and at this moment curve 244 is complementary with the dynamic relationship of segmented mode and operation point, and clutch torque 241 couplings that are equivalent to and follow the tracks of.

Draw the minimum clutch torque relevant in the operating mode shown in Figure 15 d and add one according to the synthetic characteristic of method of divergent belt by the classification tracking with the operation point.

Figure 15 e illustrates a characteristic by the given clutch torque of minimum clutch torque 243, can not in the steady state value scope, represent, but function of time, at this moment should the minimum clutch torque mate with a classification function 245, then carry out the accurate instantaneous tracking of moment as for specified clutch torque 241 (greater than minimum clutch torque), do not need to mate according to divergent belt.

Figure 16 illustrates the gearshift figure of conventional H type gearshift.In order to select each gearshift groove 250, between each a gearshift groove 250 and a gear selecting road 251, distinguished respectively.The stroke of being passed by in the groove 250 in gearshift by gear level 218 is called as the gearshift stroke and comes mark.The sense of motion of gearshift stroke 252 and gear selecting stroke 251 is represented with corresponding arrow in Figure 16.

The position of gear level 218 can be by two potential devices, grasp as linearity potentiometer particularly.Here a potential device is monitored the gearshift stroke, another potential device monitoring gear selecting stroke.In order to carry out watchdog routine, same can be contained in the controller, so that gearshift stroke and/or gear selecting stroke are collected and put in order.The action principle of watchdog routine makes an explanation by Figure 17.The signal of interest that the watchdog routine of having drawn in Figure 17 is used is to the change curve of time t.The ordinate mark is equivalent to the collected gearshift stroke 252 that P segments arbitrarily in computing machine.Drawn the separately curve of 260 couples of time t of a gear level signal, direct and collected gearshift stroke 252 is proportional.

The change curve that gear level signal 260 is drawn into conforms to a representative type shift process.The time t that gear level 218 is docked on its position approximately here to mark in 8.3 seconds always ends.Gear level signal 260 shows that this is as the representative type vibration in service of travelling until this time point ends.This concussion in moment transmiting system, produce voluntarily and additional instance as since the unfairness of traveling lane from the vibration of external excitation.Gear level 218 is pushed into gearshift groove 250 after the time point that was marked with 8.3 seconds, and the phase signals of shifting gears like this 260 is that 200 increments rise to about 480 increments from an about value.This value keeps more constant times.This is equivalent to, and client stops time of the inside or this is passing through the required time of gear selecting stroke 251 of not stopping.Put into certain shelves at last.Gear level signal 260 increases to about 580 increments, and keeps more constant times.This be equivalent to for the synchronous time gap of let-in transmission device converter speed ratio.Gear level signal 260 is raised to one and the corresponding value of new let-in shelves later on.

Gear level signal 260 is done filtering with the digital to analogy conversion of adjustable delay time in addition, obtains a linearizing filtering signal 261 of following gear level signal 260 like this.A steady state value and a balanced signal relevant have been applied on the filtering signal 261 with the drive torque of driver element 202.Thus the resultant signal of Xing Chenging as a comparison signal 262 be drawn in the diagram of curves among Figure 17.

The identification of gearshift intention concerns by gear level signal 260 and comparison signal 262 time dependent monitoring to be carried out.When in case the signal change curve of gear level signal 260 change curves and comparison signal 262 intersects, then counting machine zero setting of a gearshift intention and starting.This time point marks with t1 on figure.The count value of gear level counting machine decides to continue to move to the maximum count value of a regulation on the calculator pulse.Draw a period that accurately records thus, at this moment between in the collected gearshift of verification intention.The control signal that calculator during this period of time can be arrived at any time stops, zero setting again.This class control signal can pass to from bonded assembly sensor device nearby.These sensors are monitored other influence factor, such as drive torque, and other motion change processes of bonded assembly load or gear level 218.In case the test value that this sensor device is received is contradictory with the gearshift of being discerned intention, then a control signal is passed on the gearshift intention counting machine.Moment transmiting system can prevent flase tripping by described watchdog routine thus.When gearshift intention counting machine reaches the count value of regulation and when not having control signal to pass to, then gearshift intention signal just passes to a subordinate's operating system.

The formation of comparison signal 262, do detailed being explained as follows according to Figure 18:

When gear level signal 260 changes to another other yardstick, then draw consequent filtering signal 261.In order to form comparison signal 262, filtering signal 261 is increased a steady state value and a balanced signal relevant with drive torque.This steady state value must select greatly like this, it is the vibration of the change curve of gear level signal 260 Rotation type of gear level 218 can be the time owing to automobile runs, before neither one gearshift intention arrives and crossing with the change curve of comparison signal 262, and the phenomenon of flase tripping appears.This must carry out automatically, and when becoming zero, then balanced signal becomes zero when drive torque (for example because the fuel backflow).The time point of drive torque feedback marks with t2 here.Comparison signal 263 in the middle of then comparison signal 262 is equivalent to one, this signal is formed by just adding from filtering signal 261 and a steady state value together.Therefore steady state value coordinates possible vibration wave amplitude (as the amplitude) operation of gear level in the favourable mode of alerting ability to the gearshift link rod.

Figure 19 illustrates the change curve of gear level signal 260 when carrying out a slow especially shift process.Carry out slowly like this when the gear level operation, the danger that consequently exists gear level signal discord comparison signal to intersect.Such result makes the gearshift intention of proposition might be able to not guarantee identification.For this reason, watchdog routine enlarges additional one and represented gear level is changed promptly the monitoring that the gear level stroke with the function of time changes here.So the variation of gear level signal 260 is monitored like this, promptly in time window, monitor determined stroke in the specialized range outside the scope that the gear level of being failure to actuate is taken and change whether be lower than a limit.This class limit descends and is considered to change irrelevant gearshift intention with comparison signal 262.Gear shift operation begins at time point t3 under the situation shown here.The monitoring range of gear level stroke automatically spreads to second stroke S2 by stroke S1 at the beginning.The monitoring period window expands to time point t5 from time point t4.The stroke variable of determining in a S scope in Δ t during this period of time is lower than the limit of a storage, and then a gearshift intention signal passes on subordinate's the moving system.

The mode of operation of gearshift intention counting machine is described according to Figure 20.In the exemplifying shown on figure at time point t5, in gear level signal 260 change curves a peak value will appear.This peak value causes intersecting of gear level signal 260 and comparison signal 262.Gearshift intention counting machine thereby starting on time point t5.Simultaneously and gearshift intention counting machine start simultaneously a time meter still arranged.When peak value in gear level signal change curve 260 falls after rise, and when therefore synthetic new crossing of gear level signal 260 and comparison signal 262, this time meter receives a signal.Time meter stops, and the minimum time of a shown time and a storage compares.The time that is recorded by time meter under current situation determines to be lower than the time of storage.After this a control signal sends on the gearshift intention counting machine.Therefore gearshift intention counting machine stops and returns and place zero.Peak value on the passage period point t5 thereby identification gearshift intention, after this starting of gearshift intention counting machine, but gearshift intention signal does not continue to send to subordinate's operating system, because received a control signal in the period that the operation of gearshift intention counter faster is limited.Different therewith is time point t6 identification be actual current gearshift intention, and make arrangement with described method.Behind time point t6, there is a gearshift intention signal to deliver to subordinate's operating system rapidly.

Shown in Figure 21 is the figure of clutch actuation system Figure 30 0 of using of an automobile.This system is mainly by the part system motors in observed total distance, control apparatus 301 (a for example electric regulator), and a link system 302 and a moment transmiting system 303, (as power-transfer clutch) formed.

Control apparatus 301 is to make machinery or hydraulic pressure or compressed-air controlled control apparatus.Be placed between control apparatus 301 and the moment transmiting system 303 (as power-transfer clutch) link system without a doubt can connecting rod or the hookup of hydraulic pressure realize.The structure arrangement of one hydraulic efficiency pressure system is shown among Figure 21, at this moment one sends cylinder 304 by a conduit under fluid pressure 305 and a reception cylinder 306 connections.

In sending cylinder 304 and/or in receiving cylinder 306, can lay a device as power support usefulness.This can be made as coil spring or cup spring as the device that power supports usefulness.

Moment transmiting system 303, as power-transfer clutch can be a friction clutch and/or a self-adjuster and one self-regulating by wearing and tearing, and the power-transfer clutch of balance (as SAC one power-transfer clutch).

A kind of is to have done to check according to the variation that may occur each P subsystem to make below as effective adaptive preceding topic with the adaptive control method of clutch actuation system distance.

For make this adaptive can be effective, must at first understand fully in the various piece system which kind of problem or effect be play a major role and can influence adaptive.For this reason should be brief again top listed parts are done deeply narration, and point out the soruce of error that it is main and the scope of problem.

Engine moment generally is to determine by a performance diagram or calculate according to engine speed and suction pressure (in other words being the throttle gate opening angle).While can be considered the terms of settlement to kindred circumstances and same system in order to determine engine moment.Because error on the performance diagram and/or the deviation when surveying suction pressure, deviation can take place in the result on the moment of reality.The situation of auxiliary machine group of received moment is a unknown number in addition.Further inaccuracy is just just arranged when definite real engine moment in this point.Characteristics in this engine control gear (unloaded regulating control, the control apparatus of beating, thrust detaching gear) are introduced wrong result equally when determining engine moment.Fitting at that time the engine control of this characteristics in order to guarantee to determine what engine moment can be paid attention in adaptive preparing.The electronic system that for example signal is dealt with that for example exists on the thrust detaching gear, this electronic system is thrown off the clutch control mechanism that a signal is continued to pass to electronics according to thrust, to guarantee to determine as far as possible exactly engine moment.

Control apparatus 301 can be made electric regulator.The instruction of a rated travel is the instruction of clutch pressure plate for example, changes by one stroke control or levelling in this system.In order to make system's levelling not have lasting levelling deviation, understanding traveled distance is necessary for levelling.Traveled distance can be measured, and therefore can use for other calculating.From traveled distance by the clutch characteristics curve of a theory actual moment M on can the theory of computation _KTstthTherefore (needn't force to use the time response of rated travel and levelling to be similar to by a model obtains).

Another approach is the additional auxiliary parameter that obtains an adaptive usefulness, calculates the push rod power of a theory by stress and resistivity.Utilize this push rod power can calculate second theoretic actual moment M _KIst2When push rod power changes, on clutch torque, must reflect to change and.False if not this situation is then proofreaied and correct accordingly.Here have another possibility, can utilize comprehensive power to transmit, at this moment the actual value of each power can be made comparisons with the analog value of actual moment, so that determine, and the situation that whether will find the count value on the power-transfer clutch of fitting and/or throw off to conform to.

If as the hookup between control apparatus and power-transfer clutch, then the viscosity of the temperature of system and transmission medium is most important with a hydraulic efficiency pressure system.That will consider equally has duct length and a pipeline section because temperature traverse and temperature not simultaneously this parameter to change and can cause inaccuracy.Expanded at the connecting tube that receives cylinder and send between cylinder as mentioned above, as length variations and changes of section, by the clutch position of a mistake of such signalisation.

Moment transmiting system can be a power-transfer clutch or a power-transfer clutch of levelling automatically.So-called influence is to measure the variation of thrust and friction coefficient variation.The variation that relevant thrust produces is narration more below later on.An adaptive device can be made pre-determined arrangement as the function of operation energy loads to the variation of The friction coefficient energy loads and the variation of friction radius.

One adaptive preparing can be predesignated clutch torque and just do adaptively from certain minimum value, sees Figure 22.

The adaptive identification of having presetted the amount of various piece system of a whole set of control system of power-transfer clutch actuating mechanism (comprising electrical motor, control apparatus, a hydraulic efficiency pressure system and a power-transfer clutch).At this moment the various piece system is analyzed, and judge possible soruce of error separately, and its consequence is made assessment, solves or reduced.At this moment also can check which soruce of error and consequence thereof serious, which then can be ignored.

Adaptive device can dispose the addition component of being considered.Absolute value and the absolute altitude that can understand which and moment under the effect of addition component have no relations.The addition component can be facilitated by auxiliary unit (energy consumer before the clutch).Also can compensate error on the engine moment diagram of curves by the addition component.

Be a graphic model or a square gearshift figure who has considered the addition component shown in Figure 23.In square 400, be expressed as and have the driving engine that applies engine moment Man.Square 401 is to the consideration such as the addition component of error on auxiliary unit and the motor characteristic curve figure.Consider thus on hookup 402, to introduce and proofread and correct moment Mkorr, at this moment obtain:

M _ankorr＝M _an-M _korr

Considered the moment of inertia of system at square 403.This means only consider escapement but or also can be a moment of inertia that drives the section part.Form the dynamic moment of proofreading and correct for the moment of determining to apply 403 at power-transfer clutch 404.

This moment can be proofreaied and correct and adaptive one component that doubles.Needing the reason of multiplication component is the friction coefficient that is for example changing, for example as the function and the altered bonding top layer spring of spring performance of temperature.

If that suppose depart from mutually with friction coefficient reality, then the high more then error of the clutch torque of Yao Qiuing is also big more.

Square 406 is expressed as the automobile body in Figure 23 diagram of block.

An adaptation procedure can be drafted thus, when requiring an energy consumer adaptive, and clutch torque (M _Ksoll-korr) be reduced to the degree that power-transfer clutch occur to be slided.This can explain like this: M wherein _Korr(compensation value of unit) is by following formula

M _Ksoll-korr=K _Mo+ (M _An-M _Korr)+M _SicherRaise and end when occurring up to skidding.Skid during the stage this, clutch torque is by the given accurate function of a regulation (M for example always _KorrDescend by domatic) end when raising reduces up to skidding again.Can assess energy consumer from this relation, at this moment assessment can be to carry out all the time, can be that each skid cycle carries out once or assessment several times.

In ideal conditions, promptly the characteristic curve of Shi Ji clutch characteristics curve and hypothesis conforms to, and the moment composition that the Mkorr value comprises has energy consumer composition and the required composition of this device along separate routes.According to this estimation with calculate to consider that error in the engine moment can be described as and cause by friction coefficient.Because the energy consumer born do not occur, so negative adaptive energy consumer is carried out adaptive and interpretation as a low excessively friction coefficient.The reception of the moment of each energy consumer is restricted in addition, and at this moment absolute altitude separately must be a unknown number.Thereby can be used as too high friction coefficient interpretation during the value of overstepping the extreme limit.

The fixing of the boundary on top and limit can be avoided by selecting cleverly, promptly avoids limit to select too greatly and the friction coefficient change detection gets too slow.Can avoid equally limit too a hour additional energy consumer interpretation be the variation of friction coefficient.

During only in pulling force execution in service, this can be an advantage, at this moment adaptive should carrying out on the top of minimum moment when adaptive.

This simple adaptation method (seeing Figure 14) causes adaptive model break into one an addition component (energy consumer etc.) and a multiplication component, only finishes by the decision and the data of limit.Then be assumed to be the addition component in the limit, the conduct multiplication component outside the limit is the error that is caused by other reasons, for example engine moment.

Error in the engine moment or interference append on energy consumer and the clutch characteristics curve by this way.

The example that Figure 24 provides is the example under the different loads state in the stage of skidding, specialize for one, one be addition with one be the multiplication the assessment curve.

Curve 450 is depicted as the time dependent curve of the clutch torque of correction.451 provide the time dependent curve of engine speed nmot, and the 452nd, the time dependent curve of transmission device input speed nGetr.

Engine speed equates approx with transmission device rotating speed 452 on the time point 41 that observation in this embodiment begins.The clutch torque of proofreading and correct then illustrates the characteristic that decline is arranged in time slightly.

Skid in period 453, engine speed 451 surpasses the transmission device tachometer value slightly.Clutch torque 450 increases after the phase detection of skidding.Periods 456 intrinsic motivation rotating speed 451 reach relative maximum, increasing of clutch torque allows engine speed descend again.

When begin periods 454 top of the waves taking place, is exactly the increase of short time engine speed.Do not have adaptive generation in this stage, transmission device rotating speed 452 and then engine speed 451 rotates with lagging behind.

Illustrate period 455 with period 453 and skid the stage accordingly.

Because adaptive always the operation under the slip limit of energy consumer maybe can be moved, there is skid another possibility in stage of an arrangement, the compaction degree total in this stage changing and changing, in other words on the power-transfer clutch or moment transmiting system on rated moment be positioned at different levels, for example illustrate one other engine moment and/or other load condition.Topic before one is arranged, and promptly Shi Ji energy consumer did not change, that is to say between the stage of skidding pitch time oversize be not really suitable.

If for example constant when different loading conditions, can from then on draw the result that friction coefficient hypothesis and/or that determine and/or that calculate conforms to the real friction coefficient of power-transfer clutch in stage of skidding 453 and 455 energy consumer numerical value.

Can proofread and correct friction coefficient in this case and proofread and correct by row.

Advantageously this embodiment can be divided into an addition component and the multiplication component is carried out.

When adaptive the time under the energy consumer change situation, then friction coefficient change with energy consumer change just to separate be not correct carrying out, and compensate as much as possible by raising adaptation procedure frequency.

In addition can be after changing at load, carry out in the constant stage adaptive, can be by the combination of preparing of long as far as possible time gap and other adaptive devices.

The multiplication component is adaptive in dynamic range or under the situation, and (for example top of the waves and/or in when starting) can carry out simultaneously.Under the situation of skidding, be suitable for following formula:

M _an-M _korr-(μ _Ist/μ _theo)*M _ksollkorr＝J*dω/dt

With the parameter of the detectable the unknown of this formula, μ in the formula _IstAnd μ _TheoBe the actual value and the theoretical value of friction coefficient.

Explain this adaptation procedure by Figure 25.Moment 500 time dependent characteristics for occurring shown in Figure 25, the actual moment 502 of power-transfer clutch, motor torque 501, J*d ω/dt 503, transmission device rotating speed 504 and time dependent performance corrected power-transfer clutch rated moment 505.

The engine moment 500 that occurs in 506 stages is constant, when corrected power-transfer clutch rated moment 505 does not change, must proofread and correct the variation of J*d ω/dt 503 with the variation of corrected power-transfer clutch rated moment.This condition in most of the cases satisfies, because the short time internal consumption seldom changes usually.If this change is not proofreaied and correct, corrected in other words specified clutch torque 505 does not make J*d ω/dt 503 pull to the variation of oneself, must do corresponding the correction to friction coefficient, variation as 505 surpasses 503, theoretical friction coefficient is reduced, because actual friction coefficient is less than assumed value.

Corresponding therewith, then must in reverse situation, carry out.

Directly the value of calculating or definite friction coefficient is possible by this method.So can be on the engine speed gradient be time of zero (for example in the position 507) can calculate the size of the friction coefficient of additional energy consumer because motor torque is known, the utilization following formula:

M _korr＝M _an-(μ _Ist/μ _theo)*M _ksollkorr

Because the rated moment M that is calculating _Ksollkorr505 and the actual moment 502 of actual power-transfer clutch between control apparatus is arranged, at this moment generally can not ignore regulating characteristic, in order to continue to improve adaptive quality under current intelligence, but the model of configured in advance one control apparatus.In the actual moment 502 that just can obtain the theory of a calculating by stroke measurment (as sending in the cylinder) from the traveled distance surveyed and characteristic curve on the electric controller of a power-transfer clutch electronic processing system.Can be used for substituting rated moment, and be marked as M _KIST502.So just the dynamic component that produces owing to the stroke levelling has all been included.Adaptation method to occur all be particularly advantageous under the motoring condition that skids.It also is favourable carrying out multiplication the division with component addition equally.

For adaptive another kind of possibility, be that the assessment by starting speed provides identification to a multiplication component.This simple possibility with component identification multiplication addition is present among the arrangement of starting process.On the time point of idle running, the driver is during step on the accelerator with a no load speed for driving engine, the moment of using driving engine to transmit for the compensation of self-demand and auxiliary unit.So Jia She engine moment value can think to proofread and correct the bench mark of moment values in this case.When starting process, when the driver steps on throttle, through the regular hour, the engine speed that assessment and arrangement are reached.Engine speed is relevant with the clutch torque that is applied, and at this moment clutch torque forms from the engine moment that the engine moment of reality deducts before the step on the accelerator and then.Compare by a table, see whether the due engine speed of applied force square conforms to actual practical engine speeds.When bigger deviation was arranged, the expression friction coefficient had change, then controls the friction coefficient of calculator stored and can do corresponding correction.

Shown in Figure 26 for the moment 510 that applies and engine speed 511 and transmission device input speed 512 be the curve of function with time.Be in light condition at time point 517 last automobiles,, assess auxiliary unit with the torque of power absorbed and absorption at this moment by the value in 513 scopes.In the later scope of time point 518, (determine) and can determine a rated engine speed from the engine moment value that is applied by acceleration phase, this rotating speed can contrast with the actual value 511 of engine speed, then can implement 515 and also carry out the estimation of friction coefficient therefrom.This ways and means allows to be divided into component multiplication and addition, does not at this moment have an effect in the dynamic change of control apparatus.Adaptive very superior by this method, because it only may use when starting, and the error in the engine moment signal can influence adaptive.

Another kind of possibility method for adaptive can so reach, and promptly carries out whole characteristic identification with the strong point one by one.This possibility to the system of a detectable adjusting parameter as throwing off system and the calculating of throwing off stroke adjustment can advantageously be carried out, initial in dynamic adaptation, adaption section, energy consumer moment and/or unit consume are approximate known.When not understanding the consume of energy consumer moment and unit, equally can the calculated equilibrium signal.At this moment the available digital method is carried out.

For the evident characteristics curve, the travel point and the strong point determined on curve are corresponding, the clutch torque 520 of the theory that calculates with from the clutch characteristics curve and make comparisons from the clutch torque of traveled distance 521 gained.At this moment the correction increment strong point then when deviation is arranged is suitable for following formula:

M _kopplungtheo＝M _AN-M _korr-J*dw/dt

Shown in Figure 27 be in time window 522 from the variation of the control apparatus traveled distance of actual value 522 gained, at this moment carry out the detection of engine speed 524 and transmission device rotating speed 522.By the clutch torque 520 that the strong point 526 can be determined corresponding calculating from the characteristic characteristic and the traveled distance of moment transmiting system, can make comparisons this value and actual clutch moment.Shown in Figure 27 be this parameter with the time intercropping function curve, the travel position indication by control apparatus on curve can be determined the strong point 526, and finishes the expansion of each strong point by the speed that control apparatus moves.

Clutch characteristics curve 530 for the band strong point 531 shown in Figure 28 is determined on curve and the calculating clutch torque.In addition, express adaptive scope 532, adaptive scope does not need the gamut of clutch characteristics curve is determined, if at this moment do adaptive to the moment scope that is higher than limit 533, and when being lower than limit 533, come adaptive with the method that adds a minimum value, for example Figure 15 a to 15e advised like that, then can be favourable.Like this a kind of adaptive can with provided characteristic overall irrelevant, this time error is offseted by the characteristic curve of theory.

Adaptive being accordant to reason of the strong point also affacts not on the operation operating range of the strong point, also needs extrapolated method in this scope, starts because do not pressurize in adaptive operation point and is not must pressurize and start.

The transmission system that one automobile is shown of Figure 29 a summary has a driver element 600 and one moment transmiting system 601 be connected on driver element in power stream after.An automatic transmission with hydraulic torque converter 610 is connected on after the moment transmiting system, and this change-speed box is used as conical disc and illustrates around driving device, but its ubiquity is not limited.Change-speed box also can be automatic stepless adjustable change-speed box, for example a friction wheel change-speed box or friction ring change-speed box.

Conical disc mainly is made up of a steady speed change device around driving device, and this change-speed box is made of around device 604 together two couples of

awl dish seat

602a, 602b, 603a, 603b and.

Conical disc will be received on the fixing speed change level 605 (this grade is to affact on the differential gear 606) around the change-speed box of driving device is minimum.

Figure 29 b represents until the similar structures design till the moment transmiting system 611.611 are connected on the back of transmission device 610 (such as change-speed box) in power stream.

Select compaction degree like this, do not make around device relative slip is appearred in awl dish seat around device.For fear of slip, have a control system be controlled to between the awl dish seat around the compaction degree of device, because the part of sliding can cause infringement and cause damaging around device.

Can follow the tracks of and stipulate transferable torque with an adaptive control when engine moment that applies changes, and make the idle running of the unlikely formation of change of operation point around device (as sprocket wheel).

In order to avoid dallying under the torsional vibrations situation driving on the section, must be a spot of overvoltage for well around the compaction degree that installs owing to having improved the applied force square blink.

Is suitable with an as far as possible little overvoltage to the control compaction degree, because the overvoltage meeting causes frictional loss and thereby causes efficient to reduce and cause consumption of fuel to increase.Reduce excessively to compress the danger that causes around device idle running is then arranged.

But the vibration of the carry-over moment that occurs on the change-speed box recited above can calculate and take in a control program, because can carry out adaptive with the disturbances of power relation.

The torque shock ends that this external driven one side can occur can't see in advance, for example situation of the tire that changes when the automobile band when a smooth track face sails to a thicker track face.Torque shock ends occurs on driven one side in this case, this can not precompute.Not only time relationship changes, and range value neither calculate.

In order to make change-speed box prevent this torque shock ends, then to press Figure 29 a, 29b and settle a moment transmiting system 601,611 on the section driving, it is controlled like this: make from the transferable torque of moment transmiting system always less than from the transferable torque of change-speed box.

The transferable torques control of moment transmiting system 601,602 guarantees in arbitrary operation point, but the transmitting torque of change-speed box, but be transmitting torque greater than moment transmiting system.Therefore moment transmiting system makes the safety clutch that a moment is followed the tracks of, and can have adaptedly in arbitrary operation point and control.

Adaptive control by moment transmiting system can make the compaction degree around device reduce like this, promptly reduces the safe clearance that prevents around device idle running.Thereby can improve the efficient of transmission device, make change-speed box enter unsafe danger and be unlikely.

Moment transmiting system can be used as the safety clutch of self and/or uses as steering clutch and/or as the transmission power-transfer clutch of tor-con or as the extra clutch of the adjusting usefulness of change-speed box.

Settle moment transmiting system beneficial especially on driven one side, because will drive impact on one side early than being placed on, because the swivel that also has change-speed box when moment is introduced in action in the identification of the load shock on driven one side.

Be placed on driven one side and also have its advantage in addition, change-speed box rotates on the driving engine of running when vehicle stationary, can carry out quick adjustment and/or static adjusting smoothly like this.

When moment transmiting system is placed in driven one side in order to determine and/or must consider the converter speed ratio and the loss of change-speed box for the engine moment that calculates appearance.

The invention is not restricted to detailed exemplifying graphic and that describe, but also comprise the relevant fabricate block of the characteristics that particularly can have the present invention's description and the variant that element causes.In addition with by the described characteristics of diagram and shown in the independent invention of the relevant genus of function itself also belong to scope of the present invention.
