Abstract
A method for operating a braking system for a vehicle. A braking request signal characterizing a braking request is generated by actuation of a positioning assemblage of an actuation circuit, and a target brake pressure required in an active circuit is ascertained based on the braking request signal. An actual brake pressure in the active circuit is established 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. If the braking request signal is constant over a predetermined time period, a wheel brake actuated by the active circuit is hydraulically decoupled 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 the electric motor is shut off.
