Abstract
Electronic control apparatus including a V-type multi-cylinder internal combustion engine having right and left banks of cylinders and , a crank-angle detecting device for a camshaft of one bank and which outputs a rotational-angle signal, a cylinder determination device for generating a determination signal of which cylinder is to be ignited, an intake-air volume measuring device for measuring an intake-air volume, and an ECU for inputting the intake-air volume, the rotational-angle signal and the cylinder determination signal to calculate a rotational speed and ignition timing. The electronic control apparatus is configured so that ECU inputs the rotational-angle signal from the crank-angle detecting device and predicts a signal period of the next time from a state of change in the signal period of the same bank and sets ignition timing of the next time based on this predicted result.
