<P>PROBLEM TO BE SOLVED: To prevent such inconvenience that combustion is not stably performed in an internal combustion engine when a warm-up of a purification catalyst of a purification device is requested. <P>SOLUTION: When a warm-up of a purification catalyst is requested, an engine and two motors are controlled so that the travel is performed by power based on travel power Pdrv* while continuously operating the engine at a first prescribed operation point (rotational speed Ne1 and torque Te1) when a catalyst temperature Tc is lower than a threshold Tcref (S150, S250 to S290), and the engine and the two motors are controlled so that the travel is performed by power based on travel power Pdrv* while continuously operating the engine at a second prescribed operation point (rotational speed Ne2 and torque Te2) within the range where an output from the engine is larger than that of the first prescribed operation point when the catalyst temperature Tc is equal to or higher than the threshold Tcref (S160 to S200, S250 to S290). <P>COPYRIGHT: (C)2012,JPO&INPIT |
