<P>PROBLEM TO BE SOLVED: To reduce deterioration in fuel consumption due to catalyst warm-up while reducing deterioration in emission in a hybrid vehicle using an engine as one power source. <P>SOLUTION: In the hybrid vehicle using the engine as one power source, an ECU obtains a catalyst temperature TC (S100), and when the catalyst temperature TC is lower than a catalyst temperature T1 necessary for exhaust-gas purification in an engine continuous operation (YES in S102), carries out a catalyst warm-up operation (S104). When the catalyst temperature TC is between T1 and a catalyst temperature T2 (> T1) necessary for exhaust-gas purification in engine starting (YES in S106), an intermittent inhibited operation for prohibiting an intermittent operation of the engine is performed (S108). When the catalyst temperature TC is higher than T2 (NO in S106), a normal operation allowing the intermittent operation of the engine is performed (S110). <P>COPYRIGHT: (C)2010,JPO&INPIT |
