PURPOSE:To improve a drivability, by effecting feedback control when the speed of a vehicle is higher than a low set value and the transmission of the driving power of an engine is cut off during the entire closure of a throttle valve. CONSTITUTION:When it is judged in a step 100 that the speed of a vehicle has exceeded a low set value, a transfer is made to a step 106. When the transmission of the driving power of an engine is cut off, a transfer is made to a step 102. When it is judged in the step 102 than a throttle valve is entirely closed, a transfer is made to a step 102. When it is judged in the step 102 that a throttle valve is entirely closed, a transfer is made to a step 104 in which feed-back control is performed through the quantity of air sucked into a by-pass and the quantity of fuel, to keep the rotational frequency of the engine at an aimed value. The drivability of the vehicle is thus improved. |
