<P>PROBLEM TO BE SOLVED: To warm up catalyst according to a traveling mode. <P>SOLUTION: When a hybrid priority mode is set, a temperature T22 slightly higher than a lower limit temperature at which ternary catalyst is activated is set as a completion temperature Tstop at which catalyst warm-up is completed (S530), to warm up catalyst in an engine. When an EV priority mode is set, a temperature T12 higher than the temperature T22 in the hybrid priority mode is set as the completion temperature Tstop (S520), to warm up the catalyst in an engine. According to this, excessive catalyst warm-up can be suppressed when the hybrid priority mode is set, and deterioration in emission at the next start of the engine can be suppressed when the EV priority mode is set. <P>COPYRIGHT: (C)2010,JPO&INPIT |
