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.
Disclosed herein is a technique for improving drivability of a vehicle by controlling the driving of the vehicle by a double clutch when the clutch of a double clutch transmission (DCT) is overheated. There is provided a shift control method for a hybrid vehicle with a DCT. In particular, where it is desired to perform shifting when one of clutches of the DCT is overheated, double-clutch shifting is performed using a non-overheated clutch and an engine clutch without using the overheated clutch, thereby reducing disharmonic shifting in virtue of a small difference in gear ratio during shifting and improving shifting and driving performance.
