PURPOSE:To prevent the fall of revolution of an engine by increasing fuel in response to increase in quantity of intake air before the quantity of intake air is increased, in case that the quantity of air intake is increased as the range of an automatic transmission is shifted from neutral range to Drive range. CONSTITUTION:A CPU30 constructing the main part of a control unit drives and controls an ISC valve 24 for adjusting intake air quantity, several kinds of means 9 for adjusting the operating condition of an engine, timers T1, T2 according to the several signals detected by an inhibitor switch 27 for detecting the speed change positions of an automatic transmission, several kinds of means for detecting the operating conditions of the engine. At the time of shifting from Neutral range to Drive range, the quantity of intake air is increased by predetermined quantity. In this case, the CPU30 increases the quantity of fuel, according to the increased quantity of intake air. The increasing control of the quantity of the fuel is carried out before the increasing control of the quantity of intake air at the time of the shifting. |
