Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress a disadvantage, for example, in which when a warm-up request for a purification catalyst of a purification unit is made, combustion in an internal combustion engine becomes hard to stabilize.SOLUTION: When a warm-up request for a purification catalyst is made, if a catalyst temperature Tc falls below a threshold Tcref, an engine and two motors are controlled so that while the engine is continuously operated at a first predetermined operation point (the number of revolutions Ne1 and torque Te1), a vehicle is run with a power based on a running power Pdrv* (S150 and S250 to S290). If the catalyst temperature Tc is equal to or larger than the threshold Tcref, the engine and two motors are controlled so that while the engine is continuously operated at a second predetermined operation point (the number of revolutions Ne2 and torque Te2) within a range, in which an output of the engine gets larger than that at the first predetermined operation point, the vehicle is run with the power based on the running power Pdrv* (S160 to S200 and S250 to S290).
