Definitions
- the invention relates to methods and devices for controlling motor vehicle starters.
- a motor vehicle starter conventionally comprises (FIG. 1) an electric motor M, a contactor 10, and a control circuit 20 for this contactor 10.
- the contactor 10 includes a coil B (or more) and a movable core controlling a switch K.
- a coil B or more
- a movable core controlling a switch K.
- the start switch actuates for example by the ignition key so firm, the movable core is allowed to move and act on a rod elastically coupled to a movable contact, conventionally in the form of plate intended at the end of the race to come into contact with fixed electrical supply terminals connected respectively to the positive terminal (+ Bat) of the battery and to the electric motor M.
- the switch K therefore comprises the movable contact and the terminals. When it is closed the motor M is supplied.
- the control circuit 20 includes a transistor T1, placed in series with the coil B, as well as a microcontroller 25 for controlling this transistor T1.
- the contactor 10 therefore has the role of an electric switch between a source (the vehicle battery) and the engine M, and also a role of driving gear means between the engine M and the heat engine of the vehicle. More specifically, as visible in FIG. 1 of the aforementioned document FR-A-2 795 884, the contactor 10 is located above the motor M while being parallel to the latter.
- the movable core is coupled to the upper end of a fork-shaped lever with the intervention of a spring called tooth against tooth spring.
- the lower end of the lever is adapted to act on a launcher comprising a hub, a pinion and a free wheel interposed between the pinion and the hub; said free wheel comprising an external part in the form of a cage integral with the hub, an internal part integral with the pinion and intermediate rollers between the internal and external parts.
- the pinion when it is moved by the lever via the movable core, is intended to mesh with the starter ring of the internal combustion engine of the motor vehicle, knowing that the hub of the starter geared with an output shaft adapted to be driven directly or indirectly by the electric motor M.
- a useful intensity variation is chosen in the coil B, taking into account in particular various mechanical parameters specific to the launcher considered, such as its inertia and the friction forces which it during its advancement from its rest position to its work position.
- the mass of a launcher can vary from 1 to 4 depending on whether it is intended for a starter for a small passenger vehicle or for a heavy-duty starter.
- the friction of a starter is much higher for an outgoing pinion starter than for a nose gear starter. It has been proposed in document FR-A-2 795 884 to supply the contactor coil with a variable current draw, the variation of the duty cycle, and therefore of the effective current over time, depend on the parameters of the mobile core.
- the microcontroller 25 is suitably programmed.
- the microcontroller 25 is placed on an electronic card, and the cards often differ only by programming the microcontroller.
- the card is mounted in the contactor 10 in the vicinity of the fixed core of the contactor 10 as described for example in document EP-A-0 751 545 to which reference will be made for more details.
- the risks are therefore high to confuse the cards and to mistakenly equip contactors, starters or vehicles, with unsuitable cards.
- this type of error is difficult to identify once the card is mounted in the contactor, and the latter mounts on the starter as much as the electronic circuits associated with the contactor are integrated therein.
- the invention proposes to overcome this drawback here, that is to say to identify easily and reliably the type of programming of a contactor control microcontroller, especially when it is already mounted on the starter .
- This object is achieved according to the invention by a method of supplying a motor vehicle electric starter contactor in which an effective supply signal having a chosen evolution is provided on a circuit supplying the contactor, characterized in that an additional signal is also provided on the supply circuit having a shape chosen to facilitate the identification of the evolution of the effective supply signal.
- the invention also provides a device for supplying a starter contactor of a motor vehicle, comprising a circuit for supplying the contactor and means for supplying on this circuit an efficient supply signal having a chosen evolution, characterized in that that it includes also means for supplying, on the supply circuit, an additional signal having a chosen shape to facilitate the identification of the chosen evolution of the effective supply signal.
- FIG. 1 shows a supply arrangement of a starter switch according to the state of the art
- - Fig 2 is a trace representing the evolution of a duty cycle of the supply voltage of a contactor coil
- FIG. 3 is a trace representing the evolution of a duty cycle of the supply voltage of a contactor coil, according to the invention
- Figure 4 shows a train of identification pulses according to the invention.
- FIG. 2 there are indicated on the abscissa successive instants during the displacement of a mobile contactor core (core call period), and on the ordinate the duty cycle of the supply voltage of the coil B of the contactor.
- FIG. 2 is identical to FIG. 3 of the document FP-A-2 795 884.
- the coil B is supplied via the transistor T in pulse mode of the pulse width modulation or “Puise width modulation” type. (PWM) according to English terminology, the transistor T being piloted by the microcontroller 25.
- PWM pulse width modulation
- RI pulse width modulation
- a high effective intensity crosses the coil B and the moving core is subjected to a sufficient attraction force to lift it from its rest position and to set it in motion.
- This phase is short enough to produce a high attraction force on the core only for the purpose of detaching the latter.
- the transistor T is first (up to an instant t) the seat of a duty cycle R2 substantially equal to 50 °., So that the current effective in coil B is just sufficient to overcome residual friction forces, reduced after detachment of the movable core. During this first interval, the mobile core therefore continues to move until the contactor closes, without excessive speed.
- a second interval of this second phase which elapses between instant t2 and instant t3, after a time determines or predetermines in the accidental case where the switch K could not have been closed, in particular when forces abnormally high take place in the contactor, the fork, the launcher and / or the motor M - the movable contact of the switch K not being in contact with the power supply terminals - the microcontroller 25 implements a continuous increase and progressive of the cyclic report, going from the R2 report to find the RI report. This interval makes it possible to ensure, by the progressive increase in the effective intensity, the closing of the contactor 10.
- This train of pulses is here specifically adopted with the change in duty cycle described above, to which it is inseparable since it is programmed in the microcontroller 25 simultaneously with this particular change.
- this train of pulses L constitutes an intrinsic marking or reference of this particular control signal, intrinsic to l object which it must identify, namely the behavior of the microcontroller 25.
- the pulse train here has a duty cycle R4 lower than R2, so that the effective intensity resulting from this pulse train produces no displacement of the mobile core, so that it has no mechanical effect on the contactor.
- this pulse train reside here in its total duration T (equal to the difference between t 0 and t _ ) - We therefore choose, in the present example, a different duration T for cards having different behaviors.
- This duration T also corresponds to a predetermined number of pulses.
- an operator can easily identify the number of pulses that appeared during this preliminary phase. It takes the control signal for this, for example at the output of the microcontroller 25, at the input of the transistor Tl, at the output of the transistor Tl, or even the voltage across the terminals of the coil B.
- Such an identification signal can also be detected using a detection device adapted to recognize it, for example a preprogram to react to the expected signal.
- This identification signal can, as a variant, reveal the mode of supply by being the site of a coding.
- Such a code pulse train may in particular have a duration ratio between the high state and the low state which is characteristic of the variation in intensity delivered by the card to the coil B at start-up.
- the identification can also be done by a code pulse train comprising at least two high duration levels.
- the identification signal is for example a signal of pulse width modulation (PWM) type.
- PWM pulse width modulation
- a PWM frequency of the signal is programmed, from t_ to t 0 , which is different from the frequency used after t 0 , and the identification is done by measuring the frequency.
- the signal is programmed identification with frequency modulation according to a given code.
- the train of pulses on the power supply circuit of the contactor coil (s) (here before contactor 10 operates), has a coding which makes it possible to identify the type of programming used in the microcontroller 25, without this train of pulses setting the moving core in motion (but not limited to).
- the additional signal can be chosen to have no mechanical effect on the contactor.
- the pulse tram reveals a specific programming, and makes it possible for example to distinguish between them control programming which can be very close to each other which would be difficult to differentiate otherwise. It allows for example to differentiate from adaptive programming by revealing the type of adaptation they implement.
- the additional signal is not a pulse train.
- the present invention is not limited to the embodiment described.
- the microcontroller 25 can systematically implement a continuous and gradual increase in the duty cycle even in the event of good operation.
- this increase in the duty cycle can be achieved in a non-progressive manner by abrupt increase in the duty cycle in order to find the RI ratio.
- an effective supply signal having a chosen evolution is provided on a contactor supply circuit and according to the invention an additional signal is also provided with a chosen shape to facilitate the identification of the evolution effective power signal.
