エンジンのアイドル回転数制御装置。 An engine rotation speed adjustment means for adjusting the engine rotation speed, and a mechanism for converging the engine rotation speed to a target rotation speed under a predetermined condition corresponding to an idling operating state including a condition that the throttle opening degree is approximately zero. In the engine idle speed control device, the engine idle speed control device is provided with a speed feedback control means for feedback controlling the engine speed adjustment means, and the drive system is operated to a driveable state under a predetermined condition corresponding to the idling state. ,
The idle speed control of the engine is further provided with vehicle speed feedback control means for feedback-controlling the engine speed adjustment means so that the vehicle speed converges to a target vehicle speed when the vehicle speed exceeds a predetermined value. Device.
