Abstract

Idle number of revolution of an internal combustion engine is controlled by calculating an integration correction term based on the difference of actual number of revolution of the internal combustion from a target number of revolution at the time of idling and then correcting fuel supply using that integration correction term. At the time of starting the internal combustion engine and/or immediately after starting the internal combustion engine, anticipated correction corresponding to a friction existing in the initial stage of starting the internal combustion engine is made for fuel supply.
