Abstract
A system for controlling a power propulsion unit of a hybrid type for a four-wheel-drive automotive vehicle that includes at least one electric motor part and at least one thermal engine part capable of driving the independent front and rear driving axles of the vehicle. The system includes a mechanism determining total torque set point from a request of the driver, a mechanism distributing the total torque set point, and a system optimizing the duty point, to dynamically determine the torques to be applied to each of the two driving axles and to optimize fuel consumption of the power propulsion group according to the drivability requested by the driver and driving conditions.
