Abstract:
A control system for an electromechanical brake which includes a first friction surface operably connected to an element to be braked, a second friction surface provided on a friction element which is movable against the first friction surface by an electric motor having a rotor, wherein the first and the second friction surfaces maintain a predetermined clearance in between each other, a sensor which directly or indirectly senses the angle of rotation of the rotor of the electric motor, a contact-detection means which is able to determine whether the first friction surface bears against the second friction surface and thereupon generates a contact signal, wherein a variation of the angular velocity of the rotor upon application of the first friction surface on the second friction surface is evaluated to determine the rotor angle where the first friction surface touches the second friction surface in a neutral position.
