BRAKE SYSTEM

摘要

The invention relates to a brake system of the brake-by-wire type for actuating a motor vehicle brake system, said system comprising a brake servo unit that can be actuated in accordance with the intention of the driver, both by means of a brake pedal and by means of an electronic controller and regulator. According to the invention, means for decoupling a force-transmitting connection between the brake pedal and the brake servo unit are provided in the brake-by-wire operating mode. The electronic controller and regulator (7) has a regulator circuit that regulates the distance travelled (SDs) by the output member (20) of the brake servo unit (3), whereby the target value (SDsSoll) of the distance travelled (SDs) by the output member (20) of the brake servo unit (3) is calculated in accordance with the actuation distance (SBp) of the brake pedal (1). The system is equipped with a monitoring module (24), which in the event of a malfunction, such as for example the inclusion of air or a brake-circuit failure, partially compensates the lengthening of the distance travelled (SDs) by the output member (20) of the brake servo unit (3), caused by the malfunction.
