Method for controlling a vehicle brake system, the slip of which can be regulated electronically

A method for controlling an electronically slip-controllable vehicle brake system, including:

• a master cylinder actuatable at least indirectly by a driver, a brake circuit, connected to the master cylinder, and having at least one wheel brake;
• an electronic control unit;
• a valve unit, triggerable by the electronic control unit, for modulating the brake pressure at a wheel brake of the vehicle brake system;
• a pressure generator, which is actuatable by a drive motor that is triggerable by the control unit;
• at least one sensor element, detecting an actuation of the master cylinder;
• and
• a pressure fluid reservoir, which is disposed between the valve unit for modulating the brake pressure in the wheel brakes and the intake side of the pressure generator,
• the method comprising the steps of:
• detecting an automatic braking event;
• detecting actuation of the master cylinder during the automatic braking event;
• upon detecting the actuation of the master cylinder during an automatic braking event, triggering at least one valve unit for modulating the brake pressure in a wheel brake in such a way that pressure fluid flows out of the wheel brake into the pressure fluid reservoir;
• and
• triggering in parallel with the at least one valve unit, the drive motor of the pressure generator to control the pressure drop at the wheel brake.
