The present invention relates to a technique for increasing acceleration linearity while reducing a shift shock that can occur during acceleration while shifting from a second gear to a first gear before a vehicle is stopped. According to the present invention, disclosed is a shift control method for a hybrid vehicle with a dual clutch transmission (DCT), including the steps of: requesting to reduce transmission input torque when entering a downshift from the second gear to the first gear; determining whether the vehicle is accelerated by the operation of an accelerator pedal during the downshift; and controlling to allow the reduction request amount of the transmission input torque to gradually decrease in a torque phase section in which clutch torque is exchanged after the first gear is engaged when it is determined that the vehicle is accelerated during the shift.

    본 발명은 차량의 정지전 2단에서 1단으로 변속 중 가속시에 발생 가능한 변속충격을 저감하면서 가속선형성을 증대시키는 기술에 관한 것으로, 본 발명에서는, 2단에서 1단으로 다운시프트 변속 진입시, 변속기입력토크를 저감 요청하고; 상기 다운시프트 변속 중 가속페달 조작에 의한 가속 여부를 판단하며; 상기 변속 중 가속으로 판단시, 1단기어가 치합된 후에 클러치토크를 교환하는 토크페이즈 구간에서 변속기입력토크의 저감요청량이 점진적으로 감소되기 시작하도록 제어하는 것을 특징으로 하는 하이브리드 DCT차량용 변속 제어방법이 소개된다.
