<P>PROBLEM TO BE SOLVED: To well suppress deterioration of catalyst for purifying exhaust gas by appropriately increasing a fuel supply quantity to an internal combustion engine. <P>SOLUTION: In a hybrid car 20, when an input limit Win becomes, as charging electric power, smaller than a tentative limit value Win0, and when a map for setting a second OT quantity increase coefficient tending to increase a quantity of a fuel injection quantity (S280), an excess quantity increase coefficient to correct a quantity increase coefficient defined by the map for setting the second OT quantity increase coefficient so that a fuel injection quantity is further increased until a prescribed time t0 elapses from the setting, and a spark-advance coefficient to advance spark timing of an engine 22 are set (S300), and when fuel cut is prohibited, the increase in quantity of the fuel based on the quantity increase coefficient and an excess quantity increase coefficient defined by the map for setting the second OT quantity increase coefficient and the advance of the spark timing using the spark-advance coefficient are executed from the setting of the map for setting the second OT quantity increase coefficient up to the elapse of the prescribed time t0. <P>COPYRIGHT: (C)2007,JPO&INPIT |
