Patent ID: 8186770

Claim:
A method for controlling or regulating an electronically triggerable vehicle brake system, operating on the return principle, having a master cylinder, actuatable by muscle power, for supplying at least one wheel brake of a brake circuit with brake pressure, having a device for modulating the brake pressure at the wheel brake, which device includes a pressure buildup valve, triggerable by an electronic control unit, in a first pressure fluid connection from the master cylinder to the wheel brake, and a pressure reduction valve, triggerable by the electronic control unit, in a second pressure fluid connection leading away from the wheel brake, having a pressure generator drivable by a drive motor that is triggerable by the control unit, an intake side of the pressure generator being connected downstream of the pressure reduction valve to both the second pressure fluid connection and the master cylinder, and a compression side of the pressure generator being connected upstream of the pressure buildup valve to the first pressure fluid connection, and having sensors for detecting status parameters of the vehicle brake system, the method comprising: by means of at least one sensor device, detecting the status parameters of a pedal actuation speed and/or a pedal travel distance with which an actuation of the master cylinder is effected, and by means of the electronic control unit, evaluating the pedal actuation speed and/or pedal travel distance detected and therewith ascertaining a variable trigger signal with which a driving rpm of the drive motor of the pressure generator is varied, based on a specification that a set-point value for the pedal speed is zero.
