When the remaining charge level of the battery decreases to a predetermined first determination value or less, the engine rotational speed increase control unit increases the target lower limit rotational speed of the engine or of the motor to the target lower limit rotational speed so that the operating point of the engine falls within a predetermined engine torque stable region. Then, in a state where the operating point of the engine is within the engine torque stable region, the charge control unit controls the negative torque of the electric motor so that the actual charge level by the electric motor becomes a preset target charge level. The battery can thus be recovered from an insufficient charge level.
