Abstract:
An electric oil pump for automobile transmission clutch engagement includes: a temperature sensor that measures a temperature of oil supplied to an oil supply destination relating to clutch engagement of an automobile transmission; an oil pump drive motor; a current determination part that determines a current value output to the oil pump drive motor to a predetermined current value determined such that the oil pump drive motor is capable of being driven without stopping in a case where the temperature is equal to or less than a predetermined temperature at which a torque of the oil pump drive motor becomes smaller than a load of the oil pump drive motor; and an oil pump that supplies oil to the oil supply destination by the oil pump drive motor being driven based on the determined current value.
