ABSTRACT:
A control system for an internal combustion engine for a vehicle. Upon starting of gear shifting of an automatic transmission of the engine, which increases the change gear ratio of the automatic transmission, the output torque of the engine is increased to reduce a shock generated during the gear shifting. Retrogression of the gear shifting in the inertia phase of the automatic transmission is detected, and when the retrogression is detected, the output torque of the engine is additionally increased. A control amount for additionally increasing the output torque of the engine is calculated, and the timing of termination of the additional increasing of the output torque of the engine is detected.
