A motor cooling and actuator integrated control system for an electric vehicle, which can reduce costs and power consumption, is disclosed. The motor cooling and actuator integrated control system of an electric vehicle, according to an embodiment of the present invention, comprises: a motor generating torque for driving an electric vehicle; an actuator configured in a reducer for decelerating an output torque of the motor and transmitting the same to a drive wheel; a solenoid control valve controlling hydraulic pressure by controlling an applied current according to a target pressure of the actuator; an electric oil pump (EOP) including a first outlet supplying a pressure-controlled flow to the actuator and solenoid control valve and a second outlet supplying a motor cooling flow to the motor; and a controller collecting driving conditions, controlling a number of revolutions of the EOP according to a required performance of the electric vehicle to integrally control the cooling of the motor and the pressure of the actuator.

    전기차의 모터 냉각 및 액추에이터 통합 제어 시스템이 개시된다. 본 발명의 실시예에 따른, 전기차의 모터 냉각 및 액추에이터 통합 제어 시스템은, 전기차의 구동을 위한 토크를 발생하는 모터, 상기 모터의 출력 토크를 감속하여 구동휠로 전달하기 위한 감속기에 구성된 액추에이터, 상기 액추에이터의 목표 압력에 따라 인가되는 전류 제어를 통해 제어 유압 형성하는 솔레노이드 제어밸브; 상기 액추에이터와 솔레노이드 제어밸브에 압력 제어 유량을 공급하는 제1 토출부 및 상기 모터에 모터 냉각 유량을 공급하는 제2 토출부를 포함하는 EOP(Electric Oil Pump), 그리고 주행상태를 수집하여 전기차의 요구 성능에 따른 상기 EOP의 회전수를 제어하여 상기 모터의 냉각과 상기 액추에이터의 압력을 통합 제어하는 제어기를 포함한다.
