Abstract: A method for automatically braking a vehicle using a hydraulic brake system, which includes a multi-stage valve situated between a master brake cylinder and the intake side of a hydraulic pump. To attenuate a pressure equalization process between a fluid volume on the side of the master brake cylinder and a suction line of the hydraulic pump, the control current for the valve is increased in ramp-shaped manner in order to first open a preliminary stage and then a main stage of the valve.

Abstract: A method is described for compensation of an insufficient pressure buildup in the braking system of a vehicle in the event of a failure or malfunction of a brake booster for brake force support when an actuating element of the braking system is actuated, the compensation occurring with the aid of a unit for an additional pressure buildup in the braking system and triggering of this compensation occurring as a function of a position of the actuating element in its adjustment travel. An instantaneous position of the actuating element in the adjustment travel is ascertained continuously or periodically, and the triggering and the additional pressure build-up occur as a function of this ascertained instantaneous position. Also described is a corresponding compensating system.
