Abstract
A multi-circuit electrohydraulic motor vehicle brake system includes a plurality of calipers having hydraulically actuated actuators which are hydraulically connected to an electronically controlled unit. The unit includes an electronic unit ECU and a hydraulic unit HCU. At least some of the calipers, additionally or separately include electromechanical actuators for actuating or releasing a parking brake effect. In order to cut down on electrical interfaces and electronic units in a motor vehicle, the electronic unit is connected to the electromechanical actuators via respective two separate electrical supply lines, and the electronic unit has at least one electrical switch for supplying the electromechanically actuated actuators with power.
