Abstract

An ECU performs a program including a step (S110) of resetting a shifting time fuel cut permission flag when shifting is executed before an elapsed time since shifting was executed last time reaches a determination time ("YES" in step S108); and a step (S114) of setting the shifting time fuel cut permission flag when the elapsed time since shifting was executed last time has reached the determination time ("YES" in step S112), in a case where a catalyst temperature TC is higher than a predetermined temperature TC0 ("YES" in step S104).
