Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a driving device of a hybrid vehicle, that can avoid overload operation of a motor generator when wheels are stuck.SOLUTION: A driving device of a vehicle comprises an engine 10, a clutch K0 capable of cutting off power transmission between the engine 10 and drive wheels 35, an MG 20, a clutch K2 capable of cutting off power transmission between the MG 20 and the drive wheels 35, and an ECU 100 controlling the engine 10, the MG 20, the clutch K0 and the clutch K2. The ECU 100, when an operation mode is set at an escape mode, switches between forward movement and backward movement of the vehicle by switching between a state of engaging the clutch K0 and disengaging the clutch K2 to transmit power of the engine 10 to the drive wheels 35 to move the vehicle forward and a state of disengaging the clutch K0 and engaging the clutch K2 to transmit power of the MG 20 to the drive wheels 35 to move the vehicle backward.SELECTED DRAWING: Figure 1
【課題】車輪のスタック時にモータジェネレータの過負荷運転を回避することができるハイブリッド車両の駆動装置を提供する。【解決手段】車両の駆動装置は、エンジン10と、エンジン10と駆動輪35との間の動力伝達を遮断可能なクラッチK0と、MG20と、MG20と駆動輪35との間の動力伝達を遮断可能なクラッチK2と、エンジン10、MG20、クラッチK0およびクラッチK2の制御を行なうECU100とを備える。ECU100は、動作モードが脱出モードに設定された場合には、クラッチK0を係合させ、かつクラッチK2を解放させエンジン10の動力を駆動輪35に伝達して車両を前進させる状態と、クラッチK0を解放させ、かつクラッチK2を係合させMG20の動力を駆動輪35に伝達させて車両を後退させる状態とを切換えることによって、車両の前進と後退とを切換える。【選択図】図1 |
