PROBLEM TO BE SOLVED: To improve fuel economy by appropriately securing an opportunity of an intermittent operation of an internal combustion engine even while at least one of a lift amount and a working angle of an intake valve that is controlled by a variable valve train is fixed.SOLUTION: An engine includes a variable valve gear for controlling at least one of a lift mount and a working angle as an operation characteristic of an intake valve. Even when the operation characteristic (lift amount and/or working angle) of the intake valve controlled by the variable valve gear is fixed (Yes in S110), an intermittent operation of the engine is not stopped uniformly. While charge/discharge performance of an electric storage device is not restricted and engine startability can be secured by securing cranking torque (No is determined in S150), intermittent stop of the engine is allowed. |
