The invention relates to a drive device for a vehicle. The present invention suppresses overheating of a device such as a rotating electric machine in a rotating electric machine driving mode. When the drive mode is a rotating electric machine drive mode and the vehicle is in an extremely low speed state or a stopped state at or below a predetermined vehicle speed, if it is determined that a drive request amount requested by the vehicle is greater than a predetermined request amount, the direct clutch is brought into an engaged state, and the first power transmission path is brought into a power transmissible state. Since power is output from the first power source to the first output shaft, the torque output by the rotating electric machine can be reduced. As a result, it is possible to suppress overheating of a device such as a rotating electric machine in a rotating electric machine driving mode. In addition, since the direct clutch is set to the engaged state, the loss of power in the fluid-type transmission device can be suppressed.
本发明涉及一种车辆用驱动装置。抑制旋转电机驱动模式下的旋转电机等设备的过热。在驱动模式为旋转电机驱动模式并且车辆处于预定车速以下的极低速状态或者停止状态时,在判定为车辆所请求的驱动请求量比预定请求量大的情况下,将直连离合器设为卡合状态,并且将第1动力传递路径设为能够传递动力状态,由于从第1动力源向第1输出轴输出动力,因此能够降低旋转电机输出的转矩。由此,能够抑制旋转电机驱动模式下的旋转电机等设备的过热。此外,由于直连离合器被设为卡合状态,因此能够抑制流体式传动装置中的动力的损失。
