摘要： An engine control device is configured to prevent a rotational speed of a vehicle engine from becoming abnormally low during deceleration due to an abnormal air-fuel ratio. When conditions for feedback control of engine idle speed are not satisfied and self diagnosis results of the air-fuel ratio control system are normal, the control device determines if the air-fuel ratio is in an abnormally lean state. The control device then determines if the abnormally lean air-fuel ratio state has continued without interruption for a prescribed period or longer. If so, the control device calculates an air-fuel ratio abnormality compensation quantity, e.g., adds an air-fuel ratio abnormality compensation value to an idle compensation air quantity, to increase the intake air quantity and compensate for the engine torque deficiency resulting from the lean air-fuel ratio state.

摘要： A controller 21 controls an intake air flow rate via an electronic throttle 14 based on a feedback correction amount set so that a rotation speed (NE) of an internal combustion engine (11) during idle running gradually approaches a target value (tNE). When the deviation (ΔNE) between the rotation speed (NE) and the target value (tNE) becomes equal to or greater than a predetermined value (XNE), increase correction of the intake air flow rate is performed according to the deviation (ΔNE). When the deviation (ΔNE) falls below the predetermined value (XNE), a value corresponding to the increase correction amount at that time is added to the feedback correction amount, and subsequent increase correction amounts are set to zero, so the decreased engine rotation speed (NE) can be returned to the target value (tNE) with a rapid response, and future drops of the returned engine rotation speed (NE) are prevented.
摘要翻译：控制器21基于设定的反馈校正量，经由电子节气门14控制进气流量，使得空转运行中的内燃机（11）的转速（NE）逐渐接近目标值（tNE）。当旋转速度（NE）与目标值（tNE）之间的偏差（DeltaNE）变得等于或大于预定值（XNE）时，根据偏差（DeltaNE）来进行进气量的校正，。当偏差（DeltaNE）下降到预定值（XNE）以下时，与反馈修正量相对应的增加校正量的值相加，随后的增加校正量被设定为零，因此发动机转速降低（NE）可以快速响应返回到目标值（tNE），并且防止返回的发动机转速（NE）的将来下降。
