Abstract:
A method for controlling a mechanical torque transmitted to a driving wheel of a hybrid motor vehicle includes dividing a stroke of a vehicle acceleration pedal at a variable neutral point position into a first braking-adjustment stroke and a second acceleration-adjustment stroke, determining, within the first braking-adjustment stroke in which an electric motor of the vehicle operates as a generator, a regenerative braking torque setpoint for the electric motor based on a depression of the accelerator pedal and based on of a value of maximum energy recovery torque established based on a first function stored in a memory, and providing a value of maximum recovery torque depending on a vehicle speed. The first function assumes a value of substantially zero for an upper limit speed corresponding to the vehicle speed at the moment of coupling and decoupling of the electric motor by a connection device of the vehicle.
