Abstract:
A method for activating the switchover valve of a brake circuit which is configured to build up brake pressure independently of the driver within the context of a vehicle standstill-holding function, is described, in which: the vehicle standstill is detected and, as long as the driver operates the brake during the standstill, the switchover valve is activated via a first current intensity other than zero (iUSV1) during a first phase; and the switchover valve is activated via a second current intensity other than zero (iUSV2) during a subsequent second phase; the first current intensity being selected in such a way that the switchover valve just closes at this current intensity; and the second current intensity being selected in such a way that the switchover valve is securely closed at this current intensity.
