Abstract
A solenoid valve is to be controlled in such a way that an armature of the solenoid valve assumes an intermediate position between an opened position and a closed position and the armature oscillates about this intermediate position with small deflections. For this purpose, a setpoint current value is generated on the basis of a target current value, wherein a ripple current value is superimposed on the target current value; this setpoint current value is compared with a measured current value and a differential current value is generated therefrom; an actuating current value is generated from this differential current value in a current regulator; and a control signal for controlling the solenoid valve is generated from this actuating current value in a control signal generator.
