<P>PROBLEM TO BE SOLVED: To further suppress promotion of degradation of purification catalyst in a purification device. <P>SOLUTION: When braking is requested in the midst of running while operating an engine, the engine executes catalyst degradation suppression control to control operation with fuel injection being performed (S150), in addition to when catalyst temperature Tc is equal to or greater than thresholds Tcdref1 (S130), when the catalyst temperature Tc is less than the threshold Tcdref1 and equal to or greater than the threshold Tcdref2, or when the unexecuted percentage Rr of catalyst degradation suppression control is equal to or greater than the threshold Rref, also when an energy storage percentage SOC of a battery is equal to or greater than the threshold Sref and the battery is charged, and cumulative air amount Ga is equal to or greater than the threshold Gref, while vehicle speed V is equal to or greater than the threshold Vref (S170, S190-S210). <P>COPYRIGHT: (C)2012,JPO&INPIT |
