The invention discloses methods and control systems for controlling an electronically controllable brake actuating system for automotive vehicles, with a depressurized pressure medium supply reservoir (4), with at least one pressure source (20) which can be controlled by an electronic control unit (32), said pressure source being used to apply pressure to the wheel brakes (7,8,9,10) of the vehicle, with pressure sensors and pressure control valves (inlet valve 17,18; outlet valve 27,28) being associated with said wheel brakes, said pressure control valves being controllable in an analog manner by means of an electric variable in dependence on the differential pressure applied to them and connecting the wheel brakes (7-10) to the pressure source (20) in a pressure increase phase, being closed or becoming closed in a pressure maintenance phase and connecting the wheel brakes (7-10) to the pressure medium supply reservoir (4) in a pressure reduction phase. To permit adapting the dependence between the electric variable and the differential pressure to manufacture spread and aging effects, as well as to changing environmental conditions, the present invention arranges for the electric variable in the pressure control valve (inlet valve 17, 18; outlet valve 27, 28) that is to be identified to be slowly varied in the pressure maintenance phase until a noticeable pressure change takes place in the wheel brake (7, 8) associated with said pressure control valve (inlet valve 17, 18; outlet valve 27, 28), whereupon the dependence of the electric variable on the differential pressure is corrected.
