The present invention relates to a method to control gear shift for a hybrid vehicle, which is able to minimize a change in torque transferred to a driving system, thereby reducing noise due to a backlash. According to the present invention, when a tip-in operation of an accelerator pedal is generated in a process of regenerative braking during a downshift, the method to control gear shift for a hybrid vehicle comprises: a step where a control unit limits a motor torque to a reference torque range, which is smaller than the current motor torque, to provide the motor torque to a transmission; a step where the control unit controls a clutch torque on a release side to full lock for a certain period; and a step where, after the full lock control, the control unit releases a part of the clutch torque on the release side to synchronize the motor speed with the input shaft speed of an application side.

    본 발명은 구동계에 전달되는 토크 변동을 최소화하여 백래쉬에 따른 소음을 저감하기 위한 것으로, 본 발명에서는 다운쉬프트 변속 중 회생제동 과정에서 가속페달의 팁인 조작 발생시, 제어부가 현재 모터토크보다 작은 기준토크범위 내로 모터토크를 제한하여 변속기에 제공하는 모터토크제한단계; 제어부가 해방측 클러치토크를 소정시간 동안 풀락 제어하는 풀락단계; 및 상기 풀락 제어 이 후, 제어부가 해방측 클러치토크를 일정부분 해제하여 모터속도를 결합측 입력축속도에 동기시키는 동기단계;를 포함하여 구성되는 하이브리드 차량용 변속 제어방법이 소개된다.
