Description
Technical field
The present invention relates to Control of Electric Vehicles technical field, specifically a kind of trailer brake and acceleration system.
Background technique
The trailer of caravan or bearing goods can be all pulled in external almost most of station wagon, do so to mention significantly
The delivered payload capability of high station wagon, meet car owner with vehicle requirement, but have stringent want to station wagon articulated vehicle at home
It asks, is primarily due to this scheme for increasing loading capacity of vehicle of articulated vehicle and has the following problems：1, special when vehicle suddenly accelerates
It is not when going up a slope anxious accelerate, to increase suddenly and act on due to pulling force on the tie point of station wagon and trailer, in addition such as
Modern most of station wagons are all monocoque body, easily station wagon are caused to damage, tie point damage, cause trailer with it is small-sized
Car disengages, and causes accident.2, when vehicle is brought to a halt, when especially descending brakes, due to the velocity inertia of trailer, pole is caused
Big extruding force acts on the tie point and station wagon of station wagon and trailer, in addition nowadays most of station wagons are all
Monocoque body easily causes station wagon to damage.3, today become increasingly popular in station wagon recycling braking energy, trailer
Braking energy can not recycle.The considerations of in view of the above safety issue, trailer are promoted relatively difficult at home, are badly in need of effective skill
Art penetration concept is solved.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the present invention provides a kind of trailer brake and acceleration system, tool
It has the advantage that：1, when vehicle suddenly accelerates, when especially upward slope suddenly accelerates, since pulling force increases suddenly and acts on small
On the tie point of type car and trailer, in addition nowadays most of station wagons are all monocoque body, station wagon is easily caused
Damage, tie point damage cause trailer and station wagon to disengage, cause accident, after this technology scheme of the invention, towing vehicle
The pulling force increased suddenly between trailer is first by hydraulic connector (containing helical spring) release a part, in hydraulic company
While connecing device and be stretched, oil pressure sensor pressure reduces, and controller connects super-capacitor module group and switched reluctance machines,
Switched reluctance machines high instantaneous torque accelerates by trailer, most of remaining pulling force has been buffered, to solve asking for existing scheme
Topic.2, when vehicle is brought to a halt, when especially descending brakes, due to the velocity inertia of trailer, great extruding force is caused to act on
On the tie point and station wagon of station wagon and trailer, in addition nowadays most of station wagons are all monocoque body, pole
Station wagon is easily caused to damage.The extruding force increased suddenly after this technology scheme of the invention, between towing vehicle and trailer
First by hydraulic connector (containing helical spring) release a part, oil pressure sensor pressure compressed simultaneously in hydraulic connector
Power increases, and controller connects switched reluctance machines for power generation mode, and switched reluctance machines moment, reversed large torque was by trailer system
It moves and charges to super-capacitor module group, most of remaining extruding force has been buffered, to solve the problems, such as existing scheme.3, it hangs
Switched reluctance machines dynamic brake, which recovers energy, when vehicle slows down gives super-capacitor module group, super-capacitor module group when trailer accelerates
Trailer is driven to provide energy for switched reluctance machines, since the super-capacitor module group used in this technology scheme of the invention can be fast
Fast charge and discharge, switched reluctance machines have large torque starting and high current power generation, so splendid solves existing scheme trailer
The irretrievable problem of braking energy.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of brake of trailer and acceleration system, including switched reluctance machines and switched reluctance motor controller, the switch
By super-capacitor module communication connection, the switched reluctance machines further join for reluctance motor and switched reluctance motor controller
The power device of dynamic trailer realizes that the movement of trailer and brake stop；
The switched reluctance motor controller and 12V is solar powered and accumulation power supply is powered connection, the 12V solar energy
Power supply and accumulation power supply, which are also powered, is connected to trailer signal system and connection towing vehicle signal system, the trailer signal system
It cooperates with connection towing vehicle signal system and realizes that trailer is connected with the head and the tail of towing vehicle；
The switched reluctance motor controller also receives the signal of external oil pressure sensor, and the oil pressure sensor is mounted on
In oil groove inside hydraulic connector.
Fig. 1 working principle is when towing vehicle accelerates or trailer speed is lower than tractor, and hydraulic connector is elongated, oil
Pressure drop is low, and numerical value of the oil pressure sensor by signal strength lower than normal value is input to switched reluctance motor controller, switching magnetic-resistance
Electric machine controller, which exports, gives switched reluctance machines main story signal, and super-capacitor module group is switched reluctance machines power supply, switchs magnetic
Motor main story driving trailer is hindered when trailer speed and essentially identical traction vehicle speed, hydraulic connector stress very little, oil pressure
Normally, oil pressure sensor exports normal value to switched reluctance motor controller, switched reluctance motor controller cut-out switch magnetic resistance
Motor, trailer, which enters, drives at a constant speed state.
When towing vehicle slows down or brakes, hydraulic connector is compressed, and oil pressure increases, and oil pressure sensor is by signal strength
Numerical value higher than normal value is input to switched reluctance motor controller, and switched reluctance motor controller is exported to switched reluctance machines
Anti-pass signal, switched reluctance machines are the charging of super-capacitor module group, and trailer is braked in switched reluctance machines anti-pass until trailer speed
When degree and essentially identical traction vehicle speed, hydraulic connector stress very little, oil pressure is normal, and oil pressure sensor export normal value to opening
Reluctance motor controller, switched reluctance motor controller cut-out switch magnetic group motor are closed, trailer, which enters, drives at a constant speed state.
Further, helical spring plays the role of buffering and limiting for hydraulic connector, and 12V is solar powered and energy storage
Circuit is that switched reluctance motor controller and trailer signal system are powered.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention provides a kind of brake of trailer and acceleration system, tool
It has the advantage that：1, when vehicle suddenly accelerates, when especially upward slope suddenly accelerates, since pulling force increases suddenly and acts on small
On the tie point of type car and trailer, in addition nowadays most of station wagons are all monocoque body, station wagon is easily caused
Damage, tie point damage cause trailer and station wagon to disengage, cause accident, after this technology scheme of the invention, towing vehicle
