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.

Method for controlling the tightening torque of an improved electromechanical brake

A braking system for a motor vehicle including a main braking circuit, an auxiliary electric braking circuit configured to perform parking braking, a first electronic control device which controls i) the main braking circuit to actuate a first braking member and a second braking member, and ii) in the auxiliary electric braking circuit, a first electric actuator of the first braking member, and a second electronic control device which controls, in the auxiliary electric braking circuit, a second electric actuator of the second braking member. A motor vehicle including such a braking system and to methods for controlling such a braking system.

Braking system for a motor vehicle

A brake actuator comprising a DC motor, a computer configured for: measuring, over time, a current drawn by the motor and a voltage between the terminals of the motor; implementing a Kalman filter in order to compute, from the measured current and voltage, a filtered current drawn by the motor and a filtered rotational speed of a shaft of the motor; computing, from the value of the filtered current and the value of the filtered rotational speed, a clamping force that is produced by the actuator; controlling the motor such that it stops when the computed value of the clamping force reaches a predetermined setpoint value.
