Definitions

  • the present invention relates to the control of electronically controlled motor vehicle starters.
  • a starter D which includes an electric motor M mounted between a terminal B + power supply to battery voltage and ground.
  • Electric motor supply is controlled by a contactor 1 mounted between said terminal B + and the motor M.
  • This contactor 1 is a relay which includes a plunger core (not shown) actuated by a winding call 2 and a holding coil 3 for pushing and maintain a power contact in the closed position 1a.
  • the call winding 2 is mounted between the end of the motor M which is opposite to the ground and the winding 3, said coil 3 being connected to ground by its end opposite.
  • the coils 2 and 3 are connected to the source of a transistor 4, for example from field effect type, the drain of which is connected to the terminal B +, via the key switch contact 6.
  • This transistor 4 is controlled in all or nothing or progressively, by a microprocessor 5 - also connected to the power supply terminal B + - which injects a control voltage on the gate of transistor 4.
  • Ce microprocessor 5 is for example, as illustrated on Figure 1, integrated with relay 1 and transistor 4 to inside the starter housing. He can also be placed outside the starter, in any location of the vehicle.
  • such a starter has the advantage of being autonomous, that is to say that it does not have no other electrical connection than those used by non-electronic conventional starters, namely a control cable allowing connection with the key contact 6, a cable for the power supply of the motor M, a return to ground by the carcass of the starter.
  • the microprocessor 5 manages several functions. In particular, it controls the automatic starter stop when the vehicle's engine is sufficient launched. Also, it implements protections various; for example, it cuts power to the starter when overloads appear on the motor M or when said motor M is in overspeed; also it cuts the power to the starter when supply overvoltages are generated.
  • a first solution that could be considered would consist in providing a sub-circuit allowing, during measurement operations, supplying the coil (s) contactor in parallel with the supply by the transistor 4.
  • the solution according to the invention consists of a device for controlling a starter switch motor vehicle with a management unit which manages the starter power supply and which includes means for detecting operating anomalies and cut the starter power when such anomaly is detected, characterized in that the unit of management further comprises means for detecting on a input intended to be connected to the contact switch of the vehicle a signal which commands the inhibition of protective functions.
  • This device is used with a circuit intended for be mounted between the management unit and the switch of the vehicle and characterized in that it comprises means to generate a signal which controls the inhibition of protection functions of the management unit.
  • FIG 2 there is shown a circuit 7 which is intended to be mounted between the contact switch 6 and an analog / digital converter input of the microprocessor 5 when you want to be able to perform a control on the starter.
  • This circuit 7 allows, when closing the contact switch 6, to generate a signal intended to be recognized by microprocessor 5, this being programmed to control when it detects said signal, inhibition of the different functions of starter protection.
  • This inhibit control signal can be all kinds for example a voltage signal or of intensity recognizable by its amplitude and / or its duration and / or its frequency and / or its number of pulses and / or by special binary coding, etc.
  • the signal generated consists of a voltage calibrated at a level U 0 , which, when the contact switch 6 is closed, is sent for a duration T 0 at the input of the microprocessor 5.
  • U 0 is chosen to be greater than that of the minimum operating voltage of the microprocessor 5 and less than the value of the lowest voltage which may appear on the vehicle before the starter is started.
  • U 0 is equal to 6 +/- 0.5 volts.
  • the duration T 0 during which the input voltage of the microprocessor is maintained at level U 0 is chosen to be large enough to prevent parasitic variations of said voltage from being liable to be confused by the microprocessor 5 with the inhibition control signal .
  • T 0 can for example take the value of 20 milliseconds or a higher value.
  • the circuit 7 includes a relay 8 whose switch 9 is mounted between on the one hand a terminal F intended to be connected to the contact switch 6 of a starter and other share a terminal E intended to be connected to an input of the microprocessor 5.
  • terminal E is for example intended to be connected to the starter terminal D which is normally connected to switch 6.
  • the coil of relay 8 - referenced by 10 - is mounted between ground and terminal F, to which it is connected by a resistor R 1 .
  • Circuit 7 also includes a Zener diode 11 which is mounted between ground and terminal E, being mass passing towards said terminal.
  • a resistor R 2 is mounted in parallel with the switch 8 between the terminals E and F.
  • the circuit 7 also includes a capacitor 12 mounted in parallel between the two ends of the winding 8.
  • the operator mounts circuit 7 between the contact switch 6 and the starter terminal D which is normally connected to said switch.
  • the Zener diode 11 imposes a voltage U 0 at the input of the microprocessor 5, while the relay 8 closes.
  • the capacitor 12 allows, if the mechanical inertia of the relay 8 is not sufficient for the switch 9 to close after T 0 , to increase the closing time of said switch.
  • the voltage received at the input of the microprocessor 5 when the switch is closed contact 6 is of the type illustrated in FIG. 3.
  • the microprocessor 5 implements, each time that it detects the closing of the contact switch 6, a comparison processing on the value of the voltage that it receives as an input to verify whether this voltage takes or not the value U 0 during the duration T 0 (step A in FIG. 4).
  • the microprocessor 5 activates the control process of transistor 4, as well as the different protection functions (step B).
  • the microprocessor 5 controls the inhibition of the protection functions and the closing of the transistor 4 (step C).
  • the solution which has just been described which consists to use a muting signal generation circuit protective functions, has the advantage of allow the starter to be powered off electronic protection functions without requiring additional connectors.
  • the interface circuit which has just been described can also be integrated into a test device.
  • a testing device could be used indifferently to test the electronic starters and conventional starters.
