Abstract
A method is described for determining a control signal for a controllable pressure medium control valve of an electronically slip-controllable power braking system. The underlying power braking system is equipped with an actuating unit including a displaceable actuating element, the displacement of the actuating element determining a throughput of pressure medium through the pressure medium control valve. In the opened state, the pressure medium flowing through the pressure medium control valve causes flow forces on a valve closing element. Under certain circumstances, these flow forces have a closing effect on the valve closing element, thus throttling the possible pressure medium throughput, and cause undesirably high pressure differences in the interior of the pressure medium control valve. To avoid these effects, it is provided that the pressure medium control valve be controlled using a control signal dependent on the speed of an actuation of the actuating element.
