Electric oil pump control method for operating transmission of hybrid vehicle

An electric oil pump control method for operating a transmission of a hybrid vehicle which is driven by a first motor, a second motor, and an engine, comprising:

• determining, by a controller, a number of revolutions of a low-pressure pump mounted within an electric oil pump based on a lubrication flow amount of the first motor, a lubrication flow amount of the second motor, a cooling flow amount of the first motor, and a cooling flow amount of the second motor;
• determining, by the controller, a number of revolutions of a high-pressure pump mounted within the electric oil pump based on a control flow amount of a clutch mounted within the transmission and a lubrication flow amount of a rotation driver mounted within the transmission;
• and
• determining, by the controller, a maximum value of the determined number of revolutions of the low-pressure pump and the determined number of revolutions of the high-pressure pump as a number of revolutions of the electric oil pump.
