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.

Abstract: A system for a hybrid power unit of an automotive vehicle having at least one thermal engine, at least one electric motor, with an accelerator pedal that represents a power control means actuated by the vehicle driver, and an electronic control unit. The system includes a mechanism generating a first return force on the pedal. An electronic control unit is adapted, when an exclusively electric operation mode of the vehicle is activated, to control the force generation mechanism so that it generates a second force higher than the first one when the stroke of the pedal reaches a predetermined threshold.
