Disclosed is a torque vectoring device. According to an embodiment of the present invention, the torque vectoring device comprises: a reduction mechanism which has a motor/generator as a driving source, and reduces rotational power of the motor/generator; a differential mechanism to absorb a difference between rotation numbers of a left and a right wheel, and transfer rotational power transferred from the reduction mechanism; and a torque vectoring mechanism to adjust a torque ratio distributed to the left and the right wheel. The torque vectoring device is arranged on a line of a left and a right output shaft power-connected to the differential mechanism. The torque vectoring mechanism comprises: a torque vectoring control motor; a first planetary gear set having a first, a second, and a third rotary element, wherein the first rotary element is fixed and connected to one output shaft among the left and the right output shaft, and the third rotary element is gear-connected to the torque vectoring control motor; and a second planetary gear set having a fourth, a fifth, and a sixth rotary element, wherein the fourth rotary element is connected to the differential mechanism to transfer power, the fifth rotary element is fixed and connected to the third rotary element, and the sixth rotary element is fixed and connected to a housing. The torque vectoring device is applied to a high-performance environmental vehicle such as one-motor e-all wheel drive (AWD) to minimize power loss to improve fuel efficiency performance and improve turning performance. 토크 벡터링 장치가 개시된다. 본 발명의 일 실시 예에 따른 토크 벡터링 장치는 모터/제너레이터를 구동원으로 하며, 상기 모터/제너레이터의 회전동력을 감속하는 감속기구, 좌우측 바퀴의 회전수 차이를 흡수하면서 상기 감속기구로부터 전달되는 회전동력을 전달하는 차동기구, 및 상기 좌우측 바퀴로 배분되는 토크 비율을 조절하는 토크 벡터링 기구를 포함하며, 상기 차동기구와 동력 연결되는 좌우측 출력축 선상에 배치되는 토크 벡터링 장치에 있어서, 상기 토크 벡터링 기구는 토크 벡터링 제어모터; 제1, 제2, 제3 회전요소를 보유하며, 상기 제1 회전요소가 상기 좌우측 출력축 중, 하나의 출력축과 고정 연결되고, 상기 제3 회전요소가 상기 토크 벡터링 제어모터와 기어 연결되는 제1 유성기어세트; 및 제4, 제5, 제6 회전요소를 보유하며, 상기 제4 회전요소가 상기 차동기구에 동력 전달 가능하게 연결되고, 상기 제5 회전요소가 상기 제3 회전요소와 고정 연결되며, 상기 제6 회전요소가 하우징에 고정 연결되는 제2 유성기어세트를 포함하며, 1모터 e-AWD(All Wheel Drive)와 같은 고성능 환경차에 적용되어 동력 손실을 최소화하여 연비 성능을 향상시키고, 선회 주행 성능을 향상시킨다.
