Abstract
The invention relates to a technique for operating a regenerative electrohydraulic motor vehicle brake system comprising a master cylinder that can be supplied with a hydraulic fluid from a reservoir, an electromechanical actuator for actuating a piston accommodated in the master cylinder and a stop valve provided between the master cylinder and the reservoir. According to an aspect of this technique, the method comprises the step of controlling the electromechanical actuator when the stop valve is closed to generate a hydraulic pressure on a wheel brake that is fluidically connected to the master cylinder. The method further comprises the step of activating a regenerative brake operation and of controlling the stop valve to open, the master cylinder remaining fluidically connected to the wheel brake and the electromechanical actuator being controlled to maintain the hydraulic pressure on the wheel brake at least to some extent.
