When an engine start command is generated to an engine that is in a stopped state, engine start control for cranking the engine and starting fuel combustion after increasing the engine speed is performed. In the engine start control, one of a first start pattern in which an initial combustion speed is higher than a resonance speed of the engine, and a second start pattern in which the initial combustion speed is lower than the resonance speed of the engine is selected according to the speed ratio (gear position) of a transmission. Cranking torque in the second start pattern is lower than the cranking torque in the first start pattern.
