In a hybrid vehicle including a gasoline engine and an electric motor capable of applying an assist force to the gasoline engine, the electric motor is controlled so as to increase the assist force applied to the gasoline engine when a knocking is detected by a knock sensor mounted on the gasoline engine. Thus, even when a gasoline of a low octane value is used, the drivability of the vehicle can be prevented from being degraded.
