Claim 0:
1. A method for operating a brake system for a vehicle, the method comprising the following steps:
generating a brake request signal which characterizes a brake request, by actuating a positioner system of an actuating circuit;
ascertaining a setpoint brake pressure required in an active circuit based on the brake request signal;
setting an actual brake pressure in the active circuit according to the setpoint brake pressure using a pressure generation device by moving a displacement piston of the pressure generation device using an electric motor of the pressure generation device to actuate a wheel brake coupled with the active circuit; and
under a condition that the brake request signal is constant over a predefined time period, carrying out a pressure modulation, which includes varying the actual brake pressure, while the brake request signal remains constant, by performing multiple times: (i) setting the actual brake pressure in the active circuit to a value that is greater than the setpoint brake pressure, and (ii) lowering the actual brake pressure until the setpoint brake pressure is reached by moving the displacement piston using the electric motor.
