ABSTRACT:
An apparatus for controlling an internal combustion engine that automatically corrects an error of a reference position to prevent an erroneous calculation of a controlled-parameter so as to accurately control the internal combustion engine, the apparatus for controlling an internal combustion engine having a period measuring section for measuring a period of a plurality of reference-position areas and a period of a plurality of areas corresponding to cylinders of a reference-position signal, an angular error detection section for detecting an angular error in each reference-position area in accordance with the period of the reference-position areas and the period of the areas corresponding to the cylinders and an error discrimination section that discriminates validity of the angular error to generate a final angular error, wherein a timer control section corrects the controlled-parameter in accordance with the final angular error, and a control time setting section corrects a time controlled by the timer in accordance with the final angular error.
