If a vehicle speed VSP during EV travel is lower than a predetermined speed VSP_s and hence is in a low vehicle speed range available for motor travel by a motor/generator, engine start control using a first engine start system with the motor/generator is executed. If the vehicle speed VSP during the EV travel is the predetermined speed VSP_s or higher and hence is in a vehicle speed range unavailable for the motor travel with the motor/generator, engine start control using a second engine start system with a starter motor is executed instead of the first engine start system with the motor/generator. Accordingly, the motor/generator does not have to cover an engine start torque when VSP≧VSP_s. A vehicle speed range available for the motor travel expands by the amount corresponding to the engine start torque, and fuel efficiency can be improved.
