The present invention relates to a vehicle launch control method including the steps: confirming, by a controller, the launch condition of a vehicle; determining whether the controller sets only predetermined launch creep control torque as additional torque or sets the launch creep control torque and predetermined launch pre-control torque as additional torque according to whether or not an accelerator pedal is operated when the launch condition is satisfied; setting the additional torque by adding launch slip control torque calculated in consideration of a wheel speed difference to the additional torque when the controller determines that the wheel speed difference of both driving wheels exceeds a predetermined reference wheel speed; and controlling, by the controller, eLSD using the set additional torque.
본 발명은 컨트롤러가 차량의 출발조건을 확인하는 단계와; 상기 출발조건이 만족되면, 상기 컨트롤러가 가속페달의 조작 여부에 따라 소정의 발진크립제어토크만을 추가토크로 설정할 지, 상기 발진크립제어토크와 소정의 발진프리제어토크를 함께 상기 추가토크로 설정할 지 판단하는 단계와; 상기 컨트롤러가 양쪽 구동륜의 휠속차가 소정의 기준휠속을 초과한다고 판단하면, 상기 추가토크에 상기 휠속차를 고려하여 산출되는 발진슬립제어토크를 더하여 상기 추가토크를 설정하는 단계와; 상기 컨트롤러가 상기 설정된 추가토크를 이용하여 eLSD를 제어하는 단계를 포함하여 구성된다.
