PROBLEM TO BE SOLVED: To enhance stability of idling speed by more accurately grasping the load change quantity of an engine to correct the injection amount. SOLUTION: At the complete explosion after completion of cranking by an engine 1, the start-up time correction quantity is calculated from AT oil temperature and coolant temperature. The target injection quantity is calculated from an actual engine idling speed Ne and target idling speed Neisc. When a gear position is changed, the correction quantity at the gear change is calculated from the changed gear position and the coolant temperature to calculate the target injection quantity. By so doing, the injection quantity is corrected at the engine startup and the gear change in expectation of the load change quantity of the engine 1, whereby the injection quantity control can be performed corresponding to the load of the engine 1 so as to stabilize the engine idling speed Ne during idling.
