The invention relates to a method and to an automatic control system for actuating an electronically controlled brake actuation system for motor vehicles. The inventive system comprises a pressureless accumulator (4) for the pressure agent, and at least one pressure source (20) actuated by an electronic control unit (32). Wheel brakes (7, 8, 9, 10) of the vehicle can be impinged upon with the pressure of said pressure source (20). Pressure control valves (inlet valve 17, 18; outlet valve 27, 28) are associated with said wheel brakes and are actuated in an analogous manner by means of an electrical value. Said pressure control valves link the wheel brakes (7-10) optionally with the pressure source (20) or with the pressure agent accumulator (4). In order to allow for an adaptation of the volume flows to be controlled to the volume requirements and to bring about the desired pressure change speeds, the electrical value is limited according to the hydraulic differential pressure ( DELTA p) when the pressure control valves (17, 18; 27, 28) are actuated.
