Abstract
A braking method for a motor vehicle including a hybrid or electric propulsion system, a hydraulic braking system, an electric braking system recuperating electrical energy, a brake pedal, systems to assist with driving of the vehicle, and a vehicle electronic stability control system. The method includes: selecting one of torque setpoints from between a pedal torque setpoint relating to position of or force supplied to the brake pedal, and a torque setpoint relating to the driver assistance systems; formulating a hydraulic braking torque setpoint independent of a state of the pedal by the electric or hybrid propulsion system; acquiring information relating to stability of the vehicle; formulating a hydraulic braking torque setpoint and an electric braking torque setpoint intended for the hybrid or electric propulsion system based on the selected torque setpoint, the independent hydraulic braking torque setpoint, and the information relating to the vehicle stability.
