Abstract:
1. A method for controlling a motor vehicle including driven wheels, brakes, a means for recovering energy generated by braking, and a torque transmission mechanism transmitting torque from the driven wheels to the energy recovery means, the method comprising: a) acquiring a braking instruction and at least one dynamic characteristic of the motor vehicle; b) controlling the energy recovery mechanism according to a recovery control setpoint calculated as a first function of the braking instruction and of the at least one dynamic characteristic acquired in a); and c) controlling the brakes according to a braking control setpoint calculated as a second function of the braking instruction and of the at least one dynamic characteristic acquired in a), wherein in a), a value of an output parameter of the energy recovery mechanism is acquired, and wherein in b), the recovery control setpoint of the energy recovery mechanism is calculated by a preventive filter which filters the braking instruction to attenuate an amplitude of the braking instruction around a resonant frequency of the torque transmission mechanism, and the recovery control setpoint of the energy recovery mechanism is further calculated by a corrective filter which filters the output parameter to damp out oscillations of the torque transmission mechanism.
