A method for controlling launching of a vehicle provided with a dry-type clutch according to the present invention comprises: a feedforward component calculation step of calculating, by a controller, when launching of a vehicle starts by a driver operating an acceleration pedal, a target engine speed based on the operation amount of the acceleration pedal, and calculating a feedforward component which is a part of the torque to control the clutch by using a time change rate of the target engine speed and current engine torque; a feedback component calculation step of calculating, by the controller, a feedback component which is a part of the torque to control the clutch in accordance with the difference between the target engine speed and the current engine speed; a compensation torque calculation step of calculating, by the controller, compensation torque by using the current engine torque and a clutch torque estimation value estimated as being currently transferred by the clutch; and a clutch control step of controlling, by the controller, a clutch actuator which drives the clutch by adding the feedforward component and the compensation torque.
본 발명은 운전자의 가속페달 조작에 의해 차량의 발진이 개시되면, 컨트롤러가 상기 가속페달 조작량에 따른 목표엔진속도를 구하고, 상기 목표엔진속도의 시간 변화율과 현재의 엔진토크를 이용하여 상기 클러치를 제어할 토크의 일부인 피드포워드성분을 산출하는 피드포워드성분산출단계와; 상기 컨트롤러가 상기 목표엔진속도와 현재의 엔진속도 차이에 따라 상기 클러치를 제어할 토크의 일부인 피드백성분을 산출하는 피드백성분산출단계와; 상기 컨트롤러가 현재의 엔진토크와 상기 클러치가 현재 전달하고 있는 것으로 추정되는 클러치토크 추정치를 이용하여 보상토크를 연산하는 보상토크산출단계와; 상기 컨트롤러가 상기 피드포워드성분과 피드백성분 및 상기 보상토크를 더하여 상기 클러치를 구동하는 클러치액츄에이터를 제어하는 클러치제어단계를 포함하여 구성된다.
