Abstract:
An engine has a variable valve actuation device for controlling an actuation characteristic of an intake valve that is an amount of lifting the intake valve and/or a working angle on the intake valve. When the intake valve, having the actuation characteristic (or lifted in an amount and/or worked by a working angle), as controlled by the variable valve actuation device, has the actuation characteristic fixed (YES in S120), a range applied to set therewithin an output that the engine is required to provide is limited to be narrower and a power storage device's controlled target SOC is raised to be higher (S150, S160, S170) than when said actuation characteristic is not fixed (NO in S120).
