DRIVE January 25, 2024
Source
A vehicle drive device includes a drive shaft to be driven by a drive source, a rotation transmission unit that transmits rotation input from the drive shaft to a wheel, a mechanical oil pump that generates a hydraulic pressure by the rotation of the drive shaft, an electric oil pump that electrically generates a hydraulic pressure, a hydraulic control device that supplies lubricating oil to the rotation transmission unit based on the hydraulic pressures generated by the mechanical oil pump and the electric oil pump, a drive circuit that controls electric power to be supplied to the electric oil pump, and a control unit that controls a drive condition of the drive circuit. The control unit stops the drive circuit and shuts down the electric oil pump when a temperature of refrigerant for cooling the drive circuit is equal to or higher than a third start temperature.
