Abstract

In a plug-in hybrid vehicle that includes an EHC, an ECU eliminates a sulfur poisoned state by supplying external electric power to the EHC when it is necessary to eliminate a state in which adhesion to a catalyst in the EHC degrades a function of the catalyst and external charging is being performed. On the other hand, when it is necessary to eliminate the sulfur poisoned state, the external charging is not being performed, and operation of an engine is permitted, the sulfur poisoned state is eliminated by operating the engine.
