1. A method for optimizing meterability of brake force in ABS braking with a brake-by-wire brake system, said method comprising the steps of:
sensing a driver brake request by way of a pedal force simulator,
identifying a trigger point (A) of the ABS braking,
correcting the sensed driver brake request such that, upon identifying the trigger point (A) during a reduction of the sensed driver brake request, the corrected driver brake request is reduced to an extent that ABS braking is no longer present, and
implementing the corrected driver brake request by building up a corresponding brake pressure in a brake device of the brake system.
