A method for controlling a motor vehicle equipped with wheels, brakes, a recovery device for recovering energy generated in braking, and a torque transmission chain from the wheels to the recovery device, includes acquiring a braking instruction, measuring a measured value of a dynamic characteristic of the recovery device, calculating a first intermediate setpoint with a preventive filter which filters the braking instruction so as to attenuate an amplitude of the braking instruction around a resonance frequency of the torque transmission chain, calculating a second intermediate setpoint to damp oscillations of the torque transmission chain, controlling the recovery device according to an electric motor control setpoint calculated as a function of the first and second intermediate setpoints, and controlling the brakes according to a braking setpoint calculated as a function of the braking instruction.
