An object of the present invention is to suppress an excessive increase in engine operation time during traveling in an electric travel priority mode. When a traveling power Pdrv * reaches a threshold value Pref or more in a CD mode (t11), the engine is started, and when the catalyst warm-up is requested, the catalyst warm-up is executed. After that, when the traveling power Pdrv * reaches less than the threshold value Pref (t12), the engine is stopped even if the catalyst warm-up is not completed. Thereby, it is possible to suppress the operation of the engine 22 from becoming excessively long during traveling in the CD mode. Of course, the deterioration of the emission can be suppressed by executing the catalyst warm-up. [Selection] Figure 2 |
