The present invention relates to a clutch control device for a four-wheel drive vehicle and a method thereof. The present invention comprises: an RPM sensor for sensing the engine RPM of a vehicle; a solenoid valve for interrupting hydraulic oil supplied to a clutch of a vehicle; and a control portion for controlling the flow rate of the hydraulic oil supplied to the clutch by differentially controlling the opening degree of the solenoid valve based on a wheel drive mode determined based on clutch control torque calculated based on the running state of a vehicle and whether or not the clutch needs to be lubricated, which is determined based on an engine RPM input from the RPM sensor.

    본 발명은 사륜 구동 차량의 클러치 제어 장치 및 방법에 관한 것으로서, 차량의 엔진 RPM을 감지하는 RPM 센서, 상기 차량의 클러치에 공급되는 유압 오일을 단속하는 솔레노이드 밸브, 및 상기 차량의 주행 상태를 토대로 산출한 클러치 제어토크에 근거하여 결정되는 차륜 구동 모드, 및 상기 RPM 센서로부터 입력받은 엔진 RPM에 근거하여 결정되는 상기 클러치의 윤활 필요 여부에 근거하여, 상기 솔레노이드 밸브의 개도를 차별적으로 제어함으로써 상기 클러치에 공급되는 유압 오일의 유량을 제어하는 제어부를 포함하는 것을 특징으로 한다.
