To provide a vehicular driving device equipped with two rotating electric machines acting as driving force sources for wheels, which can drive the rotating electric machines at higher efficiency.SOLUTION: A control device of a vehicular driving device can execute a first EV mode, a second EV mode and a parallel mode. In a low vehicle speed region S1 in an operation region of the vehicle, the first EV mode is executed in a first region F1 where driving force is low, and the second EV mode is executed in a second region F2 where driving force is high. In a middle vehicle speed region S2, the first EV mode is executed in the first region F1, the second EV mode is executed in the second region F2 and the parallel mode is executed in a third region F3 where driving force is higher than in the second region F2. In a high vehicle speed region S3, the first EV mode is executed in the first region F1, the second EV mode is executed in the second region F2 and the parallel mode can be executed in all regions including the third region F3 regardless of magnitude of driving force.SELECTED DRAWING: Figure 2
【課題】車輪の駆動力源となる2つの回転電機を備えた車両用駆動装置において、回転電機をより高い効率で駆動させる。【解決手段】車両用駆動装置の制御装置は、第1EVモードと、第2EVモードと、パラレルモードとを実行可能である。車両の動作領域における低車速領域S1では、駆動力が低い第1領域F1において第1EVモード、駆動力が高い第2領域F2において第2EVモードが実行され、中車速領域S2では、第1領域F1において第1EVモード、第2領域F2において第2EVモード、第2領域F2よりも駆動力が高い第3領域F3においてパラレルモードが実行され、高車速領域S3では、第1領域F1において第1EVモード、第2領域F2において第2EVモードが実行されると共に、第3領域F3を含む全領域において駆動力に拘わらずパラレルモードが実行可能である。【選択図】図2
