エンジンのアイドル回転数制御装置。 An intake air amount adjusting means that is applied to an engine used with an automatic transmission and adjusts the amount of intake air supplied to the engine, an engine temperature detection means that detects engine temperature, and a range position of the automatic transmission. Range position detection means for detecting;
Based on the range position and engine temperature detected by these detection means, the target engine speed at idle is determined to be higher in the non-driving range than in the driving range, and that the difference is small. target rotation speed setting means for setting the engine speed to increase as the engine temperature decreases; and said intake air amount adjusting means for setting the engine speed to converge to the target rotation speed set by said target rotation speed setting means during idling. In the engine idle speed control device, the engine idle speed control device is equipped with feedback control means for feedback controlling the amount of intake air according to
The engine is characterized by having a first correction means for temporarily correcting the intake air amount in the direction of increasing the intake air amount, and a second correction means for correcting the correction amount of the intake air amount by the correction means so as to decrease as the engine temperature becomes lower. This is an engine idle speed control device.
