<p>PROBLEM TO BE SOLVED: To prevent occurrence of misfires when the vibration of a vehicle in the longitudinal direction at quick acceleration or deceleration is to be prevented by means of stepwise change-over in driving wheel torque caused due to the change-over of the quantity of fuel injection. SOLUTION: While backlash restraining control or shackle restraining control permitting the quantity of fuel injection to be changed over stepwise, is being executed (102 and S103), the additional sum of a basic target throttle opening TrtB determined in response to the quantity of fuel injection at a step (S101) and an additional opening at the time of backlash restraining (S105) or an additional opening at the time of shackle restraining (S106), is adapted as a target throttle opening. This constitution thereby allows the change rate of the throttle opening to be greater than that of an opening change rate based on the quantity of fuel injection, allows the quantity of intake air to be quickly increased, and thereby prevents the occurrence of misfires due to the delay of the change in the quantity of intake air.</p> |
