Abstract
An engine control system for a hybrid vehicle having an internal combustion engine and an electric motor as driving force sources, for permitting stopping and restarting of the engine in accordance with predetermined drive conditions. The engine control system includes a fuel cutter for cutting fuel supply to the engine when the vehicle decelerates and an engine speed detector for detecting an engine speed. Stopping of the engine is initiated by cutting the fuel supply by the fuel cutter, and when the engine speed becomes equal to or lower than a predetermined speed, the engine is stopped by operating the motor as a generator and by cutting the fuel supply.
