Abstract: A method for controlling the tightening torque of an electromechanical brake for a motor vehicle, the brake including an electric motor provided with a rotary shaft intended to drive mechanical brake-clamping mechanisms. The method includes steps of acquiring data from a wheel speed sensor that takes a characteristic measurement of the speed of at least one of the wheels of the vehicle, determining, according to the data from the wheel speed sensor, a deceleration indicator characteristic of the acceleration of the vehicle, regulating the tightening torque according to the deceleration indicator.
