Abstract
An output torque control system for an internal combustion engine for a vehicle is operable during gear shifting of an automatic transmission of the engine, for changing the output torque of the engine so as to reduce a shock caused by the gear shifting. The timing of termination of the changing of the engine output torque is determined, based on a rate of change in the traveling speed of the vehicle. The changing of the engine output torque terminated at the determined timing of termination.
