用エンジンのアイドル回転数制御装置。 An engine output adjustment means for adjusting the engine output, an idle determination means for determining whether the engine is idling, a rotation speed detection means for detecting the engine rotation speed, Idle rotation speed control for an automobile engine, comprising a control means for feedback controlling the engine rotation speed by comparing the engine rotation speed with a target rotation speed during operation and outputting a corresponding control signal to the engine output adjustment means. The device includes a transmission identification means for identifying whether a transmission connected to the engine is a manual transmission or an automatic transmission, and receiving an output from the transmission identification means, and manually determining an upper limit value of the feedback control amount by the control means. An upper limit value setting means that is different between a transmission and an automatic transmission, and sets a higher value in the case of an automatic transmission than in the case of a manual transmission, and regulates the feedback control amount so that it does not exceed the upper limit value. 1. An idle rotation speed control device for an automobile engine, characterized in that it is provided with a regulating means for controlling the idle speed of an automobile engine.
