Abstract

A method shall render it possible that an especially favorable pilot control can be achieved with an electrically controllable hydraulic valve (10), 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 (10), which is determined by linking an available opening current characteristic curve (Iopen(ΔP)table) of the hydraulic valve (10) to a correction value (igrad), with the correction value (igrad) being predetermined depending on a number of parameters that are characteristic of the hydraulic valve (10).
