A method is described in which the wheel pressure in an electronically controlled motor vehicle brake system is determined. The brake system includes inlet valves and outlet valves in the wheel circuits. At least one of the valves allows adjusting the valve current. The basis for this are previously determined calibration values which describe the opening current behavior of the outlet valve. A verification of the wheel pressure is performed during a wheel pressure control operation by briefly opening the outlet valve of one brake circuit. The current prevailing in this case can be taken into account as an indicator for determining the wheel pressure.

A method shall render it possible that an especially favorable pilot control can be achieved with an electrically controllable hydraulic valve (), in particular an analog/digital inlet valve of a friction brake of a motor vehicle brake system. To this end, an actuating current is applied to the hydraulic valve (), which is determined by linking an available opening current characteristic curve (I(&#x394;P)) of the hydraulic valve () to a correction value (i), with the correction value (i) being predetermined depending on a number of parameters that are characteristic of the hydraulic valve ().
