ABSTRACT:
An engine control device comprising has a processor which receives a variety of operating state detection signals (such as an engine crank angle signal and an accelerator opening signal) and computes control quantities for an interrupt routine on the basis of a predetermined signal such as the engine crank angle signal or a signal generated at fixed basic intervals, in accordance with a predetermined program during a period of time between the predetermined signals. A means is provided for counting and/or limiting the number of times interrupt processing triggered by an activation signal for the routine is executed during the period of time between the predetermined signals whenever processing of the routine exists.
