Abstract
A controller is configured to control at least one valve of a brake system of a vehicle that is closed in a de-energized state. The controller includes an actuation device configured to actuate the valve into an open state and to keep the valve in the open state. A holding current with at least one first average target current strength is output as a control signal by the actuation device to the valve. The holding current output to the valve is increased to at least one second average target current strength which is greater than the first average target current strength while taking into consideration provided information pertaining to a current rotational speed of an electric motor of a piston/cylinder device of the brake system and/or at least one current hydraulic pressure in at least one sub-volume of the brake system.
