Abstract

In a method for controlling a selector valve situated in a hydraulic brake system of a motor vehicle, the selector valve is opened by applying an electrical signal having various control phases having different current intensities. The thermal load and the noise of the valve are significantly improved if the lengths of the control phases for the pilot stage or the holding phases are variably adapted to the driving situation.
