ABSTRACT:
Detection of which of a plurality of reference angle positions a crankshaft of an engine arrives at is executed to subsequently determine a crank angle region in which an output pattern of a cam angle signal is determined, based on which of the plurality of reference angle positions the crankshaft arrives at, whereby determination of a piston position in each cylinder is made, based on the output pattern of the cam angle signal in the crank angle region.
