WIPO Patent Application WO/2020/137565
Kind Code:
A1
Abstract:
The present invention addresses the problem of appropriately controlling cooling water and oil in accordance with a situation. This computing device controls the flow rate of cooling water supplied to a motor, and an oil pump that supplies oil to a coil of the motor from a gearbox attached to the motor. When the temperature of the oil in the gearbox is less than a first threshold value and the temperature of the coil is less than a second threshold value, the computing device restricts the flow rate of the cooling water supplied to the motor and activates the oil pump.
