Abstract
A control system for an internal combustion engine, which controls an output torque of the internal combustion engine for driving a vehicle, is provided. An engine rotational speed is detected, and a change amount of the detected engine rotational speed is calculated. The output torque control amount of the engine is corrected so that the rotational speed change amount coincides with the center value of the local minimum value and the local maximum value of the rotational speed change amount. Specifically, a torque correction amount is calculated according to a torque value which is equal to half of a difference between peak vibration torque values corresponding to the local minimum value and the local maximum value of the rotational speed change amount, and an output torque control amount is corrected with the torque correction amount.
