エンジンのアイドル回転数制御装置。 In an engine idle speed control device that slightly increases the idle speed according to various operating conditions during engine idling operation, the first idle up control is based on the shift position of the select lever and the electric load, and the first idle up control is performed based on the ON operation of the air conditioner. At least two idle up controls with a second idle up control that provides a larger throttle opening than the first idle up control.
In order to perform idle up control for each stage, a plurality of actuators for each stage are stacked, and when various operating conditions overlap, the actuator on the side with a larger throttle opening is operated to perform idle up control. An engine idle speed control device characterized by:
