ABSTRACT:
A method and an apparatus for preventing pulsations of an A/D conversion period caused when a signal indicative of an operating condition of an internal combustion engine is subjected to the A/D conversion. The A/D conversion period is provisionally determined in accordance with the number of cylinders and speed of the engine or the number of cylinders and crank angle of the engine. Two successive A/D converted values resulting from the A/D conversion operations are compared and the next A/D conversion period is corrected in accordance with the resulting difference and the engine speed. This correcting operation is repeated to control the conversion period such that the A/D conversion is always effected at the center of the pulsations.
