Title:
VEHICLE DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/158869
Kind Code:
A1
Abstract:
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).
