Abstract
A control system for an internal combustion engine for driving a vehicle, which controls an output torque of the engine, is provided. In this control system, a rapid change in a demand torque of the engine is detected, and a feedforward correction amount is generated during a correction period which is substantially equal to a resonance period of a powertrain of the vehicle, from a time when the rapid change in the demand torque is detected. An output torque control amount of the engine is corrected with the feedforward correction amount. A torque change amount integrated value is calculated by integrating an amount of change in the demand torque, and the feedforward correction amount is generated according to the torque change amount integrated value.
