Abstract
A method for controlling and/or regulating an electronically triggerable vehicle brake system, operating on the return principle, and to such a brake system in which by an adapted triggering of the drive motor for the pressure generator, the pumping quantity of the pressure generator is varied such that the difference between these flows of pressure medium to and from the master cylinder assumes a minimal value, preferably a value of zero. To that end, the driving rpm of the pressure generator is preferably varied. The trigger signal for the drive motor can be ascertained by an electronic control unit from measurement outcomes from sensors within the vehicle brake system, or it can be estimated with the aid of a hydraulic volume model stored in memory in the control unit. The trigger signal can be controlled or regulated.
