<p>PROBLEM TO BE SOLVED: To prevent generation of misfires, when vehicular longitudinal vibration in sudden acceleration or sudden deceleration is restrained by stepwise change of driving wheel torque due to sudden change of the fuel injection amount. SOLUTION: Change in speed of basic target torque to be set on the basis of the throttle valve opening and the vehicle speed is limited, so as to prevent generation of a misfire caused by excessive small or excessive large intake air amount due to delay in the change of the intake air amount of an engine. When the increase amount or the decrease amount of target torque per unit timeΔt is more than a prescribed increase allowable torque (S13) or decrease allowable torque (S14), control is performed by adopting the sum (S15) of last target torque and increases allowable torque and the difference (S20) between last target torque and increase allowable torque as final target torque. Since the sudden change in the fuel injection amount can be restrained, misfires are not generated.</p> |
