A hybrid vehicle having a function for reducing the pumping loss. When the shift is in the reverse position, when an appliance is to be driven while the vehicle is in its stopped state and when the electric motor alone is able to drive the vehicle, the fuel supply to the internal combustion engine is cut off and one of the following is performed: the engine's throttle is widely opened; the engine is decompressing by opening the intake and exhaust valves; or the engine is decompressed by closing the intake valve while opening the exhaust valve. In such a manner, the pumping loss in the internal combustion engine can be reduced. Thus, the drag on the electric motor which would ordinarily be caused by stopping the internal combustion engine can be prevented without the provision of a one-way clutch or other equipment between the internal combustion engine and the electric motor.
