Summary: | To inhibit deterioration of the driving stability when a drive mode is switched with the switching of a power source.SOLUTION: When a drive mode is switched from a first drive mode to a second drive mode, a power source is switched from a second power source to a first power source after a first engagement device is switched from a slip state to an engagement state while a second engagement device is maintained in an engagement state, so that the power source is switched while a torque distribution ratio between front and rear wheels is fixed. In other words, change in the torque distribution ratio due to the switching of the power source is prevented. Therefore, when the drive mode is switched with the switching of the power source, the deterioration of the driving stability can be inhibited.SELECTED DRAWING: Figure 9
【課題】動力源の切替えを伴う駆動モードの切替えに際して、走行安定性の悪化を抑制する。【解決手段】駆動モードが第1駆動モードから第2駆動モードに切り替えられる際には、第2係合装置が係合状態に維持されつつ、第1係合装置がスリップ状態から係合状態に切り替えられた後に、動力源が第2動力源から第1動力源に切り替えられるので、前輪と後輪とのトルク分配比が固定された状態で動力源が切り替えられる。つまり、動力源の切替えによるトルク分配比の変化が防止される。よって、動力源の切替えを伴う駆動モードの切替えに際して、走行安定性の悪化を抑制することができる。【選択図】図9 |
