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.

A method for controlling a selector valve situated in a hydraulic brake system of a motor vehicle, comprising:
- opening the selector valve by applying an electrical signal having multiple different control phases, wherein the different control phases have different current intensities;
- and
- setting a time duration of at least one of the control phases as a function of at least one braking parameter.
A control unit for controlling a selector valve situated in a hydraulic brake system of a motor vehicle, comprising:
- means for opening the selector valve by applying an electrical signal having multiple different control phases, wherein the different control phases have different current intensities;
- and
- means for setting a time duration of at least one of the control phases as a function of at least one braking parameter.
