Actuator e.g. electromagnetic injector controller, controlling method for motor vehicle, involves delaying drive current pulses one with respect to other with constant delay time, if raising edges of pulses exist simultaneously
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.
