- the life situation determination block of the power starter system 9 transmits to the torque determination block 10, the information concerning its life situation allowing it develop the final torque setpoint distributed between the heat engine on the one hand and the electric machine on the other hand, allocating, depending on the case of life, priority to the functions of powertrain management 6, to electric autonomy 7, or dynamic services 12.
- a man / machine interface can advantageously be integrated into the system according to the invention in order to constantly inform the driver and ' the other parts of the vehicle about life situations of the alternator-starter system and to acquire the driver's operating choices .
- a torque management block 12 linked to assistance for dynamic services can be integrated into the system in order to calculate the torque setpoints for compensation of transients of the heat engine, regenerative braking and anti-stalling. , using in particular the information from the block for determining the life situation of the vehicle 8, as well as the torque and the speed produced by the heat engine.
- the couple to be applied to avoid stalling the engine is the result of a calculation of the engine speed control on the idle setpoint.
- the torque to be applied in particular in the case of a down-sizing thermal engine, is calculated by slaving the sum of the couples of the two thermal and electric machines to the torque setpoint of the driver.
- a cooling block 13 ensures the start-up of a fan as a function of the temperature criteria of the heat engine and of the service and power batteries.
- any block can be modified, with fixed interfaces, independently of the others in the event of a change of the electric machine, of the heat engine and possibly of the vehicle stop or request to start conditions.
