The present invention relates to a technology for quickly performing gear shifting through motor and clutch controls without a shifting shock in regenerative braking and low gear shifting situations. More specifically, disclosed is a method for controlling gear shifting in a hybrid dual clutch transmission (DCT) vehicle, which comprises: a step of decreasing a releasing side clutch torque to release a releasing side clutch when down shifting the transmission to a gear shifting stage below a predetermined gear shifting stage at a vehicle speed equal to or less than a predetermined vehicle speed; a step of transmitting a control command for applying motor torque to increase a motor speed to be increased toward a coupling side clutch speed when a slip amount between the motor speed and the coupling side clutch speed reaches a first set value; a step of transmitting a control command for reducing the motor torque when the slip amount between the motor speed and the coupling side clutch speed reaches a second set value less than the first set value; and a step of applying a coupling side clutch torque to allow a coupling side clutch to be coupled when an actual motor torque reaches a target reduced torque in accordance with the control command for reducing the motor torque.

    본 발명은 회생제동 및 저단 기어변속 상황에서 모터 및 클러치토크 제어를 통해 변속 충격 없이 신속하게 변속하는 기술에 관한 것으로, 본 발명에서는, 소정 차속 이하에서 특정 변속단 이하의 변속단으로 다운시프트 변속 시작시, 해방측 클러치토크를 감소시켜 해방측 클러치를 해제 제어하고; 해방측 클러치 해제 후에, 모터속도와 결합측 클러치속도의 슬립량이 제1설정값에 도달시, 모터토크를 인가하는 제어명령을 전송하여 모터속도가 결합측 클러치속도를 향해 상승하도록 제어하며; 모터속도와 결합측 클러치속도의 슬립량이 제1설정값보다 작은 제2설정값에 도달시, 모터토크를 저감하는 제어명령을 전송하며; 모터토크를 저감하는 제어명령에 따라 실제 모터토크가 목표 저감토크에 도달시, 결합측 클러치토크를 인가하여 결합측 클러치를 체결하는 것을 특징으로 하는 하이브리드 DCT차량용 변속 제어방법이 소개된다.
