ABSTRACT:
A signal generator generates a crank angle reference signal containing a plurality of pulses for one ignition cycle of each cylinder which correspond to prescribed crank positions, respectively, of a corresponding cylinder. The operation of an engine is controlled on the crank angle reference signal so that reference crank positions for engine control are able to be switched over between the pulses depending upon changes in the operating condition of the engine, thereby improving the reliability and stability in the engine control. In addition, a reference position for engine control can be set as near as possible to a control timing, at which an engine control operation such as ignition, fuel injection, etc., is performed, by using an appropriate one(s) of the rising and falling edges of the pulses contained in the crank angle reference signal.
