Abstract (en)

The method involves determining the switching time point at which a movable element in the electromagnetic load reaches a defined position within a time window. The duration of the time window can be specified so that the current flowing during the time window does not exceed a threshold level. Starting from an initial value, the window duration is increased if the current is below the threshold or reduced if it is greater than the threshold. An Independent claim is also included for an arrangement for driving an electromagnetic load.

Abstract (de)

Es werden ein Verfahren und eine Vorrichtung zur Ansteuerung eines elektromagnetischen Verbrauchers, der ein bewegliches Element umfaßt, insbesondere eines Magnetventils zur Steuerung der Kraftstoffzumessung in eine Brennkraftmaschine, beschrieben. Innerhalb eines Zeitfensters wird ein Schaltzeitpunkt ermittelt, bei dem das bewegliche Element eine bestimmte Lage erreicht. Die Zeitdauer des Zeitfensters ist derart vorgebbar, daß der Strom, der während des Zeitfensters durch den Verbraucher fließt einen Schwellwert nicht übersteigt. <IMAGE>
