According to the present invention, a gear-shifting control method for a vehicle comprises: a gear-shifting requirement determination step where a controller determines whether a power-on down-shift is required, and determines whether a gear-shifting start gear is a fourth gear or a higher gear; a first torque crossing step of increasing second clutch torque while decreasing first clutch torque when a power-on down-shift from the fourth gear or a higher gear is required; a gear operating step of operating a synchronization device to gear into a target gear while maintaining the second clutch torque when the first clutch is released as a result of performing the first torque crossing step; and a second torque crossing step of releasing the second clutch while gearing into the first clutch when gearing of the target gear is completed by the gear operating step.

    본 발명은, 컨트롤러가 파워온 다운 쉬프트가 요구되는 상황인지를 판단하고, 변속 개시 변속단이 4단 이상인지를 판단하는 변속요구판단단계와; 4단 이상의 변속단으로부터 파워온 다운 쉬프트가 요구되면, 제1클러치 토크를 감소시키면서, 제2클러치 토크를 증가시키는 제1토크교차단계와; 상기 제1토크교차단계 수행 결과, 상기 제1클러치가 해제되면, 상기 제2클러치토크는 유지한 상태에서, 동기장치를 조작하여 목표 변속단을 치합시키는 기어조작단계와; 상기 기어조작단계에 의해 목표 변속단의 치합이 완료되면, 상기 제1클러치를 체결하면서 상기 제2클러치를 해제하는 제2토크교차단계를 포함하여 구성된다.
