Abstract:
1. A system for controlling a motor vehicle of the four-wheel drive hybrid propulsion type equipped with at least one powertrain on each wheelset, a first powertrain comprising at least one combustion engine, a second powertrain comprising at least one electrical machine, the vehicle also being equipped with a friction braking system on each of the driven wheels and with sensors, said system comprising: a distributing unit configured to distribute a braking request between the friction braking system and at least one electrical machine of a powertrain, said braking request including a braking torque for the friction braking system of each of the driven wheels according to requests from a driver of the vehicle, said electrical machine being configured to deliver a resistive torque; a modulating unit configured to modulate the torque setpoints of the braking systems and of the powertrains as a function of the signals from the sensors, the modulating unit including a braking coordinating device configured to output a braking request including a safe braking torque for the friction braking system of each of the driven wheels according to safety devices of the vehicle; and a powertrain control unit configured to control the powertrains, wherein the distributing unit includes a situation determining device configured to select between the braking request of the distributing unit and the braking request of the modulating unit to issue torque commands to the powertrains and to the friction braking systems in order to promote stability of the vehicle.
