Abstract
An engine control system for a vehicle having an automatic transmission in which the gear-shifting is automatically done on the basis of a predetermined shift pattern comprises an engine output control system for controlling the output power of the engine, a detecting system which detects actual shifting action of the gear train mechanism of the automatic transmission, and an engine control unit which receives a signal from the detecting system and delivers to the engine output control system a control signal for temporarily lowering the engine output power while the actual shifting action of the gear mechanism is in progress.
