ABSTRACT:
This invention relates to an arrangement for preventing unintended rolling of a vehicle. If, in the case of a vehicle which is parked properly (with the parking brake activated), it is determined that the parking brake is released, a brake pressure is generated which ensures the stoppage of the vehicle. For this purpose, a control device actuates relay valves to establish a fluid connection between a pressure accumulator and the wheel brakes. The fluid connection is maintained until a brake pressure is applied by the wheel brake cylinders which ensures the stoppage of the vehicle.
