The invention relates to a vehicle braking system, the slip of which can be regulated electronically, for which, in the event of an automatic braking process, the activation of the foot pedal by the driver, does not result in a significant actuating path. The driver therefore disadvantageously perceives different pedal actuating characteristics in the foot actuated and automatic braking operations. According to the invention, a method is proposed for controlling a vehicle braking system, the slip of which is regulated electronically, and with which pedal actuating characteristics, which are largely uniform in the different operating states of the vehicle braking system can be produced. To achieve this, a valve unit is controlled in such a way that a pressure medium flows from the wheel brake to the pressure medium reservoir and the drive motor of the pressure generator is controlled in parallel.
