EOP Electric oil pump control method for operating transmission of hybrid vehicle

摘要

A control method of an electric oil pump (EOP) for operating a transmission for a hybrid vehicle driven by a first motor, a second motor, and an engine is characterized in that the controller controls a flow rate required for lubrication of the first motor, Determining the number of revolutions of the low-pressure pump included in the EOP based on the amount of flow and the flow rate required for cooling the first motor and the second motor; and controlling the flow rate of the control flow of the clutch included in the transmission, Determining the number of revolutions of the high-pressure pump included in the EOP based on the amount of flow necessary for lubrication of the rotary drive unit; and setting the maximum value among the determined number of revolutions of the low- As the number of revolutions of the motor.
