Abstract

A control method for the idling speed of an engine, in which method, from the engine speed at the time when transition toward the idling state is determined by the switching, for example, of an idling switch to 'ON', the correction quantity of the control value of valve means for regulating the intake air quantity of the engine is set, a drop in the engine speed being avoided, and at the same time, in the convergence toward a learned value thereafter, convergence to the learned value of the valve means at a variation rate corresponding to the engine speed is made possible, whereby rapid correspondence toward feedback control is realized.
