Claim:
1. Method for operating a regenerative electrohydraulic motor-vehicle brake system having a master cylinder configured to be supplied with hydraulic fluid from a reservoir, an electromechanical actuator for actuating a piston accommodated in the master cylinder, and a shut-off valve provided between the master cylinder and the reservoir, comprising the steps of actuating the electromechanical actuator with the shut-off valve being closed for generating a hydraulic pressure at a wheel brake that is fluidically connected to the master cylinder; and activating a regenerative braking operation and actuating the shut-off valve for opening same, wherein the master cylinder remains fluidically connected to the wheel brake and the electromechanical actuator is actuated in order to at least partially maintain the hydraulic pressure at the wheel brake.
