Abstract
A spark advance angle corresponding to an optimum ignition timing is calculated in accordance with the operating condition of an internal combustion engine. Then, a reference crank angle position utilized for controlling the ignition timing is selectively determined in accordance with the value of the calculated spark advance angle so as to reduce any error in the ignition timing resulting from a change of the rotational speed of the engine.
