摘要： An engine control system for a vehicle provided with an automatic transmission including an engine output control device for reducing an engine output in response to a shift operation of the automatic transmission, brake switch for detecting a braking operation of the vehicle, a restricting element for restricting the engine output control device from reducing the engine output when the braking operation is detected during the shift operation. The engine output is not reduced when the braking operation occurs even under the shift operation so that an undue drop of engine speed can be avoided. The engine speed can be smoothly increased after the braking operation responsive to acceleration operation to thereby improve the controllability.
