Abstract: A control system for an electromechanical brake with self-reinforcement has a unit adapted to recognize brake failure, a unit adapted to detect the actual state of motion of the device to be braked, and a unit adapted to open and close the brake upon recognition of a failure dependent upon the detected actual state of motion of the device to be braked. The unit adapted to detect the state of motion detects in particular the rotational velocity of a brake disk assigned to the brake.

Abstract: The present invention relates to a motor vehicle brake system, having at least one first and at least one second electromechanical wheel brake (10), which each comprise an electric actuator for generating an actuating force and a self-boosting device for automatically boosting the actuating force generated by the actuator in order to press a friction element against a rotatable component (14) of the wheel brake (10) that is to be braked, wherein each self-boosting device comprises a wedge (18), which is supported against an associated abutment (22) and has at least one wedge face (20, 20?) disposed at an angle of slope (?). In order to realize a parking brake function, the self-boosting device of the first wheel brake comprises at least one wedge face (20), which is used to boost the force in brake operations during forward travel, and the self-boosting device of the second wheel brake comprises at least one wedge face (20?), which is used to boost the force in braking operations during reverse travel.

Abstract: An electromechanical brake has an electrical actuator which generates an actuation force and acts on at least one friction member in order to press said member to elicit a friction force against a rotational component, which is to be braked, of the brake. A self-boosting device is arranged between the friction member and the electrical actuator, said device serving to self-boost the actuation force generated by the electrical actuator, and having at least one wedge (12), which has a wedge surface (14) arranged at a wedge angle a and supported on a corresponding counter bearing (16). When the brake is actuated, the electrical actuator displaces the wedge (12) relative to the counter bearing (16) in an actuation direction (x) to press the friction component against the component, which is to be braked, of the brake.

In order to improve the adjustability of said brake (10), the electrical actuator has two drive mechanisms (34, 34?) which act upon the wedge (18) and can work against each other to generate the actuation force with the purpose of zero backlash actuation of the brake (10). In the range of low actuation forces, i.e.
