Abstract
The releases of an electromechanical parking brake are controlled by measuring the change in the intensity (I) of the electrical current provided to the control motor, or a function derived from this intensity, and by extending the release of the brake only for a determined duration (Δt) after stabilization of this intensity, in order not to unnecessarily increase the idle travel of the brake actuator nor to extend the duration of the control. The determined duration (Δt) also depends on the temperature and on the hydraulic pressure in the brake.
