A vehicle drive device provided by the present invention comprises: a transmission mechanism that is on a motive force transmission path that is between a drive source and a wheel; a hydraulic pressure control device that can supply lubricating oil to the transmission mechanism; and a control part that can output an electrical command to the hydraulic pressure control device to increase the flow of lubricating oil supplied to the transmission mechanism. When the control part has outputted the electrical command to the hydraulic pressure control device to increase the flow of lubricating oil supplied to the transmission mechanism, if the control part determines that the flow of lubricating oil supplied from the hydraulic pressure control device to the transmission mechanism is not increasing in accordance with the electrical command (time t1), the control part can determine the hydraulic pressure control device to be abnormal and impose a limit that reduces the absolute value of the torque of the transmission mechanism transmitted between the drive source and the wheel (times t1-t5).

    本发明的车辆驱动装置包括:变速机构,设置在驱动源与车轮之间的动力传递路径上;油压控制装置,能够向变速机构供给润滑油;以及控制部,能够向油压控制装置输出电气指令,以增加向变速机构供给的润滑油的流量。控制部当向油压控制装置输出电气指令以增加向变速机构供给的润滑油的流量时,若判定为从油压控制装置向变速机构供给的润滑油的流量未按照电气指令增加(时刻t1),则认为油压控制装置处于异常状态,能够执行使在车轮与驱动源之间传递的变速机构的扭矩的绝对值变小的限制(时刻t1‑t5)。
