PURPOSE:To prevent a driving shock in time of acceleration from occurring before it happens, by synchronizing an accelerating fuel quantity with each control signal to be produced in consecutive order at the specified driving range and thereby increasing the quantity gradually till it reaches the specified value. CONSTITUTION:Whether an engine speed is in the specified range or not is judged with steps 2 and 3, while whether throttle opening thetan is less than the specified opening thetaSOFT1 or no is judged. If it is discriminated as being driven by acceleration from a low load range, a flag is set with a step 11. At the time of a relief condition being effected, a throttle valve opening variation DELTAtheta is judged with a step 17. A specified factor value KSOFT set by a step 18 is used for operation of fuel injection time TOUT, whereby fuel increment immediately after transfer to an accelerating state is checked. Thus, a driving shock due to a sudden increase in engine output torque attributable to the oversupply of an accelerating fuel quantity is prevented from occurring before it happens. |
