Abstract

In a case where external electricity feed is being performed, a water temperature threshold Tref is set to a temperature T2 that is lower than in a case where the external electricity feed is not being performed, and canister puree is executed when an engine is in operation and a cooling water temperature Tw is the water temperature threshold Tref or higher. Thereby, it is possible to increase the opportunity to perform the canister purge, and to enhance evaporative emission performance. Furthermore, in the case where the external electricity feed is being performed, a maximum purge rate Pmax is set to a value P2 that is greater than in the case where the external electricity feed is not being performed. Thereby, it is possible to quickly complete the canister purge.
