A method for controlling the pressure in a hydraulic system in an electronically regulated motor vehicle brake system, including controlling the pressure using an analogized solenoid valve, and controlling the valve such that it moves into a partially open state, modulating the coil current (I) of the valve by alternation between a first (I1) and a second current value (I2). The solenoid valve held in the closed state by means of a coil current (I) corresponding to the first current value (I1). A third current value (I3) is provided for the coil current which lies between the first and second current values (I1, I2) and, during energization phases (Tp1, Tp1, Tp1) of the solenoid valve. The coil current (I) is modulated by alternation between the second current value (I2) and the third current value (I3) with the amplitude (A) predefined by the third current value (I3) and a predefined frequency. |
