Abstract

Es werden ein Verfahren und eine Vorrichtung zur Erfassung eines Schaltzeitpunktes eines Magnetventils beschrieben, bei dem der Strom, der durch das Magnetventil fließt, in einer ersten Phase auf einen Anzugswert und während einer zweiten Phase auf einen Haltewert geregelt wird, wobei der Strom während der Erfassung des Schaltzeitpunktes auf einen Erfassungswert geregelt wird. Der Erfassungswert ist kleiner als der Anzugswert und größer als der Haltewert.

Figure 00000001
A method and a device for detecting a switching point in time of a solenoid valve are described, in which the current flowing through the solenoid valve is regulated to a pick-up value in a first phase and to a hold value during a second phase, the current during the detection of the switching time is regulated to a detection value. The detection value is smaller than the tightening value and larger than the holding value.
