According to the present invention, a control method of an electric oil pump (EOP) may comprise: calculating the first number of rotation which is the number of rotation of the EOP required for controlling a brake in a transmission, the second number of rotation which is the number of rotation of the EOP required for cooling a plurality of motors, and the third number of rotation of the EOP required for lubricating the motors by a control unit; comparing the second number of rotation and the third number of rotation by the control unit after the calculation step; and operating the EOP with a result value of adding up a larger value of the second number of rotation and the third number of rotation and the first number of rotation by the control unit as a result of performing the comparison step. 이 발명의 전동식 오일펌프 제어방법은 제어부가 변속기 내부의 브레이크 제어에 요구되는 EOP 회전수인 제1회전수와, 복수의 모터 냉각에 요구되는 EOP 회전수인 제2회전수와, 복수의 모터 윤활에 요구되는 EOP 회전수인 제3회전수를 산출하는 단계; 산출단계 후, 제어부가 제2회전수와 제3회전수를 비교하는 단계; 및 비교단계 수행결과, 제어부가 제2회전수와 제3회전수 중 더 큰 값과 제1회전수를 합산한 결과값으로 전동식 오일펌프를 구동하는 단계;를 포함할 수 있다.
