<P>PROBLEM TO BE SOLVED: To reduce a control load resulting from such a fact that storage in a storage means cannot be performed by a catalyst deterioration suppressing control. <P>SOLUTION: When an input limit value WIN exceeds a limit amount WIN1 (YES in S118) when an exhaust gas purification catalyst comes within a catalyst deteriorating hot area when the requirements for fuel cut are established, i.e, the braking energy of a motor MG2 when the catalyst deterioration suppressing control is performed cannot be stored in a battery, a special control is not performed but an execution instruction for fuel cut control is outputted to an engine ECU (S110). Accordingly, a control load needed is small. In this case, since an exhaust gas temperature is lowered by an increase in OT before the input limit value WIN exceeds the limit amount WIN1, a catalyst bed temperature is lowered and, therefore, the catalyst deterioration is difficult to advance. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
