Claim 0:
1. A method for operating a braking system for a vehicle, comprising the following steps:
generating, by actuation of a positioning assemblage of an actuation circuit, a braking request signal characterizing a braking request;
ascertaining a target brake pressure required in an active circuit based on the braking request signal;
establishing an actual brake pressure in the active circuit in accordance with the target brake pressure, using a pressure generation device, by moving a displacer piston of the pressure generation device using an electric motor of the pressure generation device; and
when a condition exists that the braking request signal is constant over a predetermined time period, hydraulically decoupling a wheel brake, actuated by the active circuit, from the pressure generation device by closing an isolation valve that is disposed in a hydraulic path between the pressure generation device and the wheel brake, and shutting off the electric motor;
wherein when the condition that the braking request signal is constant over the predetermined time period is no longer satisfied: a hydraulic recoupling of the pressure generation device to the wheel brake is effected, based on a time gradient of the braking request signal, a target brake pressure necessary in the active circuit after a predetermined compensation time period is ascertained by extrapolation of the braking request signal, and the actual brake pressure in the active circuit is established using the pressure generation device in such a way that the actual brake pressure in the active circuit reaches the target brake pressure upon expiration of the compensation time period.
