Abstract

A method for holding a vehicle at a standstill includes a first phase in which the brake pressure at the wheel brakes is retained so that the vehicle is held automatically by the service brake, and the braking force is then transferred to a parking brake so that in a second phase the vehicle is held solely by the parking brake. A risk inherent in this transfer is that the vehicle may begin to slip. The distance over which the vehicle slides in uncontrolled fashion can be made substantially shorter if, in the second phase in which the vehicle is being held by the parking brake, the movement of the vehicle is monitored by sensors, and brake pressure is automatically built up by way of an actuator as soon as the fact that the vehicle is rolling away has been detected.
