The present invention relates to a technique for performing double clutch drive control when DCT clutches are overheated so as to increase drivability. More specifically, disclosed is a shift control method for a hybrid DCT vehicle, wherein double clutch shifting is performed by using a non-overheated clutch and an engine clutch instead of the overheated clutch when shift has to be performed while one clutch out of the DCT clutches is overheated so that shift and drive performance can be increased by reducing disharmony in shifting due to a small interstage ratio during shifting.
본 발명은 DCT의 클러치 과열시 더블클러치 주행 제어를 실시하여 차량의 운전성을 향상시키는 기술에 관한 것으로, 본 발명은, DCT의 클러치 중 어느 하나의 클러치가 과열된 상태에서 변속이 이루어져야 하는 경우, 과열된 클러치를 사용하지 않고 비과열 클러치와 엔진클러치를 사용하여 더블클러치 변속을 수행하여 변속시 단간비가 크지 않아 변속 위화감이 줄어들어 변속 및 주행 성능이 향상되는 하이브리드 DCT차량용 변속 제어방법이 소개된다.
