Verfahren für die Ansteuerung von Aktoren

The method involves providing four drive current pulses (P1-P4) from a power stage (11) to four actuators (12-15) through four channels (1-4) respectively. A presence of simultaneous existence of raising edges of the pulses is determined by a calculation unit of a control apparatus (10). The pulses...

Zusammenfassung:The method involves providing four drive current pulses (P1-P4) from a power stage (11) to four actuators (12-15) through four channels (1-4) respectively. A presence of simultaneous existence of raising edges of the pulses is determined by a calculation unit of a control apparatus (10). The pulses are delayed one with respect to the other with a constant delay time (DT), if the raising edges exist simultaneously.
