ABSTRACT:
There is provided a system for controlling an idling speed of an engine, comprising: engine speed detecting means for detecting an actual engine speed, integration amount calculating means for calculating an integration amount based on an error between the actual engine speed and a predetermined target idling speed, reference parameter calculating means for calculating a reference parameter based on the actual engine speed and the integration amount, target physical amount providing means for providing an appropriate target physical amount which takes a balance between the engine torque and the engine friction around the predetermined target idling speed, depending on the reference parameter, fuel injection amount calculating means for calculating a fuel injection amount in accordance with the target physical amount, the fuel injection amount being injected by the injector, and opening degree determining means for determining an opening degree of the idling speed control valve in accordance with the target physical amount, the idling speed control valve being opened by the determined opening degree.
