Abstract

A method for optimizing the meterability of brake force in an ABS braking with a brake-by-wire brake system. The method includes various steps. First, a driver brake request is sensed by a pedal force simulator. In addition, a trigger point (A) of an ABS braking is recognized. In the case of a recognized ABS braking, there is a correction of the sensed driver brake request such that, upon recognizing the trigger point (A) during a reduction of the sensed driver brake request, the corrected driver brake request is reduced to the extent that ABS braking is no longer present. The corrected driver brake request is subsequently implemented by building up a corresponding brake pressure in a brake device of the brake system.
