摘要： An engine idling speed controlling system including, for controlling the throttle valve opening appropriately, a first idling speed control means for comparing a detected signal provided from an engine speed sensor during idle running with a target engine idling speed and providing a first idling control signal, a correction value learning means for learning a long-time correction value or a just-previous correction value on the basis of a cumulative value or the newest value of a detected signal provided from a throttle position sensor during operation of the first idling speed control means, a second idling speed control means for comparing a detected signal provided from the throttle position sensor during idle running with a target throttle opening, receiving the long-time correction value and the just-previous correction value and producing a second idling control signal, and means for controlling the idle opening of the throttle valve in accordance with one of the first and second idling control signals.
