An engine automatic start stop control apparatus controls an engine of a vehicle to be automatically stopped or started in response to driving conditions of a vehicle. Particularly, the apparatus is applied to the vehicle that performs idle stop control for reduction of discharge gas. Herein, the apparatus controls the engine to restart based upon determination for restarting the engine under an engine stop mode. Namely, the apparatus controls the engine to restart if a driver depresses a clutch pedal or if a driver does not depress a brake pedal during an engine stall in which engine speed becomes zero. Thus, it is possible to restart the engine by prescribed operations even if the driver mistakenly recognizes that the engine is stopped by automatic stop control although the engine actually stalls due to an error operation of the driver so that the engine speed becomes zero. This improves drivability for the driver who handles the vehicle, particularly a hybrid vehicle which is capable of independently running by using an electric motor only.
