본 발명은 최저단으로 변속시 구배 및 차속에 따라 변속 제어 전략을 이원화하하여 신속하고 안정적으로 변속을 실시하는 기술에 관한 것으로, 본 발명은 최저단으로의 파워오프 다운쉬프트 변속이 요청되는지 판단하고; 변속요청시, 차로의 구배가 기준값 초과이고, 차속이 기준차속 초과인 경우, 해방측 클러치를 해제하며; 모터속도를 결합측 입력축속도에 동기시키고; 결합측 클러치를 체결하는 것을 특징으로 하는 하이브리드 차량용 변속 제어방법이 소개된다.

    A shifting control method for hybrid vehicles may include shifting request determining, by a controller, of determining whether power off down shifting to a lowest stage is requested, clutch releasing, by the controller, of controlling a release clutch to be released, when it is determined that a gradient of a road exceeds a reference value and a vehicle speed exceeds a reference vehicle speed when the shifting is requested as the shifting request determination result, synchronizing, by the controller, of controlling a motor speed to be synchronized with an applying input shaft speed, and clutch engaging, by the controller, of controlling an applying clutch to be engaged.
