ABSTRACT:
A microcomputer calculates a requisite time for controlling a predetermined device of an internal combustion engine. The microcomputer estimates time required for a crank shaft of the engine to rotate from a present crank angle to a designated crank angle. The microcomputer predicts a relationship between times required for the crank shaft to rotate consecutive angular regions positioned before and after the present crank angle based on measurement result with respect to times required for the crank shaft to rotate consecutive angular regions positioned before and after a preceding crank angle advanced a predetermined amount from the present crank angle.
