Abstract
An idle speed control system of an internal combustion engine controls a speed of the internal combustion engine during idling. In its attempt to shift the idle speed control after the internal combustion engine has been started from an open-loop control to a feedback control, the system brings an actual engine speed in the open-loop control to a target speed of the feedback control in a step-by-step manner. It can thus damp shock that occurs when the open-loop control is shifted to the feedback control after the internal combustion engine has been started.
