Patent ID: 8494745

Claim:
A motor vehicle brake system having a hydraulically actuatable service brake system and an electromechanically actuatable brake system, comprising: an electromechanically actuatable brake caliper, the brake caliper defining at least one operating pressure chamber; an operating element for activating a parking brake function; an actuator coupled to the brake caliper; an electronic control unit for activating the actuator; and an electrohydraulic control unit which is hydraulically connected with a service brake and serves to control or regulate service brake functions, driving stability functions and/or braking assistance functions, wherein in order to reduce stress on parts or components of the electromechanical brake system following an automatic or driver-initiated hydraulic brake actuation, and prior to completion of a temporally following electromechanical brake actuation, an electronically controlled hydraulic pressure conditioning process is carried out by the electrohydraulic control unit in the at least one operating pressure chamber of the electromechanically actuatable brake caliper, the pressure conditioning process comprising at least one of an electronically controlled hydraulic pressure reduction or an electronically controlled hydraulic pressure limitation.
