<p>The present invention relates to a method for determining a specified position of an armature in a solenoid valve, consisting of the following steps: making available the solenoid valve with the armature in a starting position; specifying a period of time (Tm) during which the armature should shift from the starting position into the position as the starting amperage (Ib) of the current (I) through the coil of the solenoid valve is reduced; determination of an extinguishing voltage, which is constant over time, for reducing the current (I) during the period of time (Tm) to a final amperage which is higher than a minimum amperage (Imin); application of the constant extinguishing voltage to the coil of the solenoid valve for at least the period of time (Tm), and measurement of the amperage of the current (I) through the coil; and recognition of the point in time (T7') at which the armature shifts into the position, by means of the variation of the amperage of the current (I) through the coil as a function of time during the period of time (Tm). In addition, the invention relates to a device for operating such a solenoid valve.</p> |
