    摘要: A crank angle position signal is generated which corresponds to rotational angles of a crankshaft and includes a specific signal for obtaining reference crank angle positions of cylinders. A cylinder identification signal is generated corresponding to the respective cylinders in accordance with the rotation of at least one of an intake-side cam and an exhaust-side cam which are subjected to VVT control. Correlation between the reference crank angle positions and cylinder groups is specified based on a combination of the reference crank angle positions and the cylinder identification signal. Cylinder identification ranges of a prescribed angular length in consideration of an advance angle and a retard angle are set based on the reference crank angle positions. The cylinders are identified based on the reference crank angle positions whose correlation with cylinder groups within each of the cylinder identification ranges has been specified, and the cylinder identification signal.

    摘要: Even if the engine is started from any crank angle position, it is possible to correctly determine the rotational direction of a crankshaft, so that fuel injection or ignition can be stopped when the crankshaft is rotating in the reverse direction. A measurement member has a plurality of angular position detection portions arranged at equal intervals in a circumferential direction of the crankshaft and a plurality of reference position detection portions at which a part of the angular position detection portions is missing. A crank angle sensor is arranged near the measurement member for generating a crank angle signal representative of the rotational position of the crankshaft. A period detector detects periods of pulses of the crank angle signal. A reference position determiner determines a plurality of reference positions based on the signal periods. A counter counts the pulses of the crank angle signal. A rotational direction determiner detects the rotational direction of the crankshaft from the number of pulses counted between a plurality of reference positions.
