Definitions

  • the present invention relates to a method and a device for the automatic shutdown of a starter of motor vehicle.
  • the acyclism represented in FIG. 1 occurs at the start of the starter operation: the peak C 1 at the start of compression is embedded in the rising edge of the second peak C 2 .
  • the starter will be prematurely stopped, before engine start, forcing the driver to try to start again.
  • the invention proposes an order for the shutdown of a motor vehicle starter, according to which we detect the ripples of a signal corresponding to the starter voltage or current and we cut the starter when these ripples disappear, which overcomes these drawbacks.
  • the solution according to the invention consists in that determines on the signal successive durations during which the tension is constantly increasing and we switches off the starter when one of these durations becomes greater than a given threshold and in what we give to this threshold of distinct values on the one hand during a polling period triggered when the starter contactor and on the other hand beyond this polling period, the polling period being of a chosen duration sufficient to encompass cases where the first and second beginning ripples of compression are substantially confused.
  • the invention also relates to a device for controlling the shutdown of a starter comprising a management unit which includes means for detecting the ripples of a signal corresponding to the voltage or to the intensity of the starter and the means to cut the starter when these ripples disappear, characterized in that this management unit implements the aforementioned treatment.
  • the invention also relates to a starter for motor vehicle comprising such a device.
  • FIG. 3 illustrates a device for controlling the supply of a starter DM which comprises an electric motor M mounted between a supply terminal B + at the voltage of the vehicle battery and ground.
  • This device comprises a contactor 1 mounted between the terminal B + of supply to the voltage U of the battery and the starter DM.
  • This contactor 1 is a relay actuated by a winding 2. One of the ends of this winding 2 is connected to the supply terminal B + . Its other end is connected on the one hand to the source of a MOSFET transistor 3 and on the other hand to a coil 5 connected to ground.
  • the drain of transistor 3 is connected to the supply terminal B + . Its gate is connected to the output of a unit 4, from which it receives a control voltage.
  • the unit 4 is for example a microprocessor.
  • transistor 3 could be replaced by any other type of switch.
  • the unit 4 generates said control voltage as a function on the one hand of the undulations of the voltage of the supply terminal B + , and on the other hand of the position of the contactor actuated by the ignition key (switch 6).
  • control unit 4 The processing carried out by the control unit 4 will now be described in detail with reference to Figures 4 and 5.
  • This treatment implements two strategies different depending on whether you are at the beginning of the starter operation or during phase normal training.
  • a polling window of a predetermined duration D ini is opened from the activation of the starter (time T 0 for which the closing of the contactor 1 occurs).
  • Unit 4 determines the durations dS 1 , dS 2 , etc. in this polling window. periods during which the voltage U of the supply terminal B + is constantly increasing. These periods correspond to the representations in mixed lines on the curve of the undulations.
  • these determinations do not start directly at time T 0 , but at a time T 0 + t ini , where t ini is chosen so as to eliminate the entire unstable period of the current draw at the time of powering up the starter motor M.
  • the unit 4 implements over the entire scanning window D ini a sampling of the voltage U and a count which is reset to zero each time a decrease occurs .
  • This constant dU has a value between 50 and 200 millivolts.
  • the starter is deactivated.
  • TS 1 is of course less than D ini and is experimentally predetermined as a function of the maximum possible values for T 1 (FIG. 1).
  • the value of TS 1 is indexed to the temperature according to a determined law or table of values.
  • the unit 4 stores the maximum value UC max of the voltage U on the different peaks encountered.
  • the unit 4 If at the end of the polling window D ini the unit 4 has not commanded the cut-off of the starter, it continues its processing in the following manner.
  • the starter is deactivated when a duration of S exceeds a predetermined value TS 2 .
  • This value TS 2 can be a fixed value for the entire period after the polling window D ini .
  • It can also be a function of the period appearance of the previous undulations, for example being a fraction of the time between the last two peaks, this duration being determined by a counting implemented by unit 4.
  • the value (s) of TS 2 may be weighted by a coefficient depending on the ambient temperature of the heat engine. Thus, at low temperature, it will be interesting to increase TS 2 to ensure a clean and complete start before stopping the starter.
  • FIG. 5 An organization chart allowing the implementation of the treatment is given by way of example in FIG. 5.
  • a first step 10 we initialize the microprocessor which constitutes unit 4 and we measure the starter temperature.
  • step 11 the microprocessor 4 determines the durations D ini , TS 1 and TS 2 as a function of the temperature measured in step 10.
  • unit 4 commands the closing of the contactor 1 (starter activation step 12).
  • the unit 4 After a time delay up to a time T 0 + t ini (step 13), the unit 4 searches for the first series of voltage samples which is increasing for a duration TS 1 during the polling window up to D ini and for a time TS 2 beyond this polling window (step 14).
  • unit 4 finds a sequence checking the above conditions, it commands the end of activation of the starter (output 15). She continues her research if not.
  • control unit 4 can be integrated into the starter or be constituted by another motor vehicle unit, for example the unit of thermal engine control.
  • the starter cut-out command motor vehicle which has just been described present other benefits than those that have been previously exposed: it is independent of the internal combustion engine vehicle, its number of cylinders and its displacement, aging of the battery and wiring, as well as starter technology and power.
