Definitions

  • the present invention relates to devices for control of a motor vehicle starter.
  • the power supply of the electric motor of a starter is controlled by an electromagnetic power contact (relay to winding) which is actuated according to the state of the contact switch of the vehicle, either directly or through electronic management integrated or not to the starter.
  • the stopping time can be to reach several seconds during which the starter emits noise at different frequencies.
  • these noises cause inconvenience as they are easily noticeable inside the cabin of the vehicle.
  • An object of the invention is to propose a device which is of a greater simplicity and allows for engine braking electric motor vehicle starter which is reliable in the time and does not penalize the performance of said starter.
  • Another object of the invention is to propose a solution for the braking of the electric motor of a starter which can be used in the case where said electric motor is controlled by such a static relay.
  • the invention proposes a device for the control of the power supply of the electric motor of a vehicle starter, in particular automobile, comprising a power switch connected in series with said electric motor, means for controlling said switch of power, as well as an auxiliary switch which bypasses said motor when the power switch opens, characterized in that said auxiliary switch is a static electronic component.
  • the invention also relates to a vehicle starter, in particular automobile, comprising an electric motor, a pinion driven said motor, means for moving said pinion to a position of rest at a position where it meshes with a crown of the heat engine, as well as a device of the aforementioned type for controlling the power supply of its electric motor.
  • the starter D shown in FIG. M electric and a power contactor 1.
  • This electric motor M is mounted between the mass and a terminal + Bat to the battery power supply.
  • the power contactor 1 is, in the particular example which is shown in the figure, a mechanical relay. It includes a contact mobile K, which is interposed between the supply terminal + Bat and the motor M, and a winding B whose feed moves the starter pinion and close the contact K.
  • This winding B is mounted between the + Bat terminal and the ground, in series with a controlled switch T1.
  • This switch T1 is by example a MOSFET transistor whose gate is controlled by voltage by an output terminal s1 of a management unit 2.
  • a switch T2 is connected in parallel with the motor M, between two ends of it.
  • This T2 switch is also controlled by the management unit 2. It is for example constituted by a transistor type MOSFET whose gate is voltage-controlled by an output terminal s2 of said management unit 2.
  • a resistor R2 mounted between the grid of the transistor T2 and the ground puts said gate at the same potential as the source of the transistor T2 in the absence of signal on the output s2.
  • the management unit 2 is constituted by a microcontroller whose an analog input e1 is connected to the power supply terminal + Bat by via a switch 3, which constitutes the start switch of the vehicle.
  • This management unit 2 is constantly powered up and is at this effect fed to the voltage delivered by the + Bat terminal via a link independent of the one on which the starter switch 3 is located. It incorporates a standby system, not shown, which allows limit electronic consumption when the vehicle is not running and This prevents the battery from being discharged too quickly.
  • the start switch 3 When the start switch 3 is closed, for example by when the ignition key is actuated, the standby system is inhibited by the appearance of the voltage of the + Bat terminal on the input e1 of the management unit 2 and the startup sequence is activated.
  • the output s1 of the electronic circuit delivers on the grid of T1 a modulated-width pulse voltage which supplies the coil B according to a current law.
  • the tension which is supplied controls the gate of transistor T1 so that a "current "high intensity” crosses the winding B to move the pinion starter and close the contact K.
  • the gate of transistor T1 is controlled so as to deliver winding B a "hold" current of lower intensity.
  • the management unit 2 When the management unit 2 detects the engine start thermal, its output s1 goes low and blocks transistor T1, which disable the starter.
  • a first possibility for this purpose is to have in series with the transistor T2 additional resistance (not shown) allowing to reduce the short circuit current.
  • the contact K is replaced by a solid state relay, which is for example a MOSFET transistor of power whose gate is controlled by an output of the unit of management 2.
  • the supply of the coil B then ensures that the displacement of the starter gear.
  • the switch Contact 3 of the starter can directly control the contact K, instead to order it through the management unit 2.
  • the relay 1 comprises two coils B1, B2, a common point of which is connected to the end of the contact switch 3 opposite the + Bat terminal.
  • the end of the winding B1 opposite to this common point is connected to the mass, while the end B2 coil which is opposed to this common point is connected to a point between contact K and motor M.
  • the gate of this transistor T2 is voltage controlled by a output s1 of a management unit 2. It is also connected to the mass by via a resistor R2.
  • This management unit 2 is powered by the + Bat terminal. She receives on an input e1 the voltage at the end of the contact switch 3.
  • the input e1 of the management unit 2 allows said unit to management to know the state (open or closed) of the ignition key 3.
  • the difference in voltage between the inputs e2 and e3 allows said management unit 2 to know the state (open or closed) of the contact of power K, compared to a reference threshold Vref.
  • the contact switch 3 When the contact switch 3 is closed, it settles in the coils B1 and B2 a current that generates a magnetic field of call for the contact K.
  • the transistor T2 is then controlled by the management unit 2 of way to be passing when the contact switch 3 and the contact of K power are open, and to be closed otherwise.
  • transistor T2 is controlled according to the following truth table:
