The present invention relates to a system and a method for controlling a torque intervention of a hybrid electric vehicle wherein transmission input torque is adjusted to slow down in order to eliminate a sense of difference and an impact due to a transmission when a gear is shifted in a hybrid electric vehicle. Therefore, the present invention maintains engine torque as possible when controlling a torque intervention, allows a hybrid starter generator (HSG) and motor torque to control a torque intervention, but the torque intervention to be controlled using an optimized division of torque in consideration of efficiency of an HSG and a motor, thereby improving fuel efficiency when a gear is shifted in a hybrid electric vehicle by providing the system and the method for controlling the torque intervention of a hybrid electric vehicle.

    본 발명은 하이브리드 차량의 변속시 변속기 입력토크를 감소 조절하여 변속 이질감 및 변속 충격을 없앨 수 있도록 한 하이브리드 차량의 변속시 토크 인터벤션 제어 시스템 및 방법에 관한 것이다. 즉, 본 발명은 토크 인터벤션 제어시 엔진 토크는 최대한 유지시키고, HSG 및 모터 토크에 의한 토크 인터벤션 제어가 이루어지도록 하되, HSG 및 모터의 효율을 고려한 최적 토크 분배를 통한 토크 인터벤션 제어가 이루어지도록 함으로써, 연비 향상을 도모할 수 있도록 한 하이브리드 차량의 변속시 토크 인터벤션 제어 시스템 및 방법을 제공하고자 한 것이다.
