ABSTRACT:
An internal combustion engine control apparatus for performing the timing control such as ignition and fuel injection timing control with high accuracy even in a transient operation state such as acceleration or deceleration. A ratio between a first interval period extending from a first reference position to a second reference position and a second interval period extending from a second reference position to the first reference position is determined. A correcting coefficient is calculated on the basis of the ratio. By using this correcting coefficient, the predicted reference position period is calculated, on the basis of which the timing control is performed.
