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.
