According to the present invention, a method for controlling DCT clutch torque of a hybrid electric vehicle comprises the following steps of: checking whether an engine of a hybrid electric vehicle is in an on state; checking whether an engine clutch is locked up if the engine is in an on state; checking whether PT mode = stop if the engine clutch is in a lockup mode; and determining a change amount of an acceleration position sensor (APS) if PT mode = stop. If the change amount of the APS is lower than or equal to 0, the method controls in a deceleration or a maintaining driving mode and fixes and controls DCT clutch torque regardless of input torque. According to the present invention, a DCT clutch can be efficiently controlled in an unstable input torque situation to reduce impacts.

    본 발명은 하이브리드 자동차의 엔진의 ON 상태 여부를 확인하는 단계, 상기 엔진이 ON 상태인 경우, 엔진클러치의 락업(LOCK-UP) 여부를 확인하는 단계, 상기 엔진클러치가 락업 상태인 경우, PT MODE=STOP인지 여부를 확인하는 단계 및 상기 PT MODE=STOP인 경우, APS(Acceleration Position Sensor)의 변화량을 판단하는 단계를 포함하고, 상기 APS의 변화량이 0 이하이면, 감속 또는 유지 주행모드로 제어하고, DCT 클러치토크를 입력토크와 무관하게 고정 제어하는 것을 특징으로 하는 하이브리드 자동차의 DCT 클러치토크 제어방법으로서, 본 발명에 의하면, 불안정한 입력토크의 상황에서 DCT 클러치를 효율적으로 제어하여 충격을 저감시킬 수 있다.
