Abstract:
A hybrid vehicle 20 sets a tentative limit value Win0 of determining a fuel increase relation with respect to a selected gearshift position SP for driving ( S220,S230,S350 ), and performs increasing correction of a fuel injection amount according to either a first OT increase factor setting map or a second OT increase factor setting map that is enabled based on a relation of an input limit Win of the battery 50 to the tentative limit value Win0. Prohibition of fuel cutoff may be cancelled, based on a relation of the input limit Win to a driving force demand in an accelerator-off state set at the selected gearshift position SP. Even in this case, the increasing correction enables temperature regulation of an exhaust gas purification catalyst, with a view to controlling deterioration of the exhaust gas purification catalyst in an actual fuel cutoff condition after cancellation of the prohibition of the fuel cutoff. The deterioration of the exhaust gas purification catalyst is thus favorably controlled, irrespective of the selected gearshift position SP.
