According to the present invention, a torque sensor device for a vehicle comprises: a main measuring member measuring a change volume of a magnetic field in accordance with a relative rotation displacement between a rotor unit and a stator unit; a redundancy measuring member measuring a change volume of a magnetic field in accordance with a relative rotation displacement between a rotor unit and a stator unit; a controller calculating a motor torque for assisting the rotation of an output axis through one or more of the measurement values of the main measuring member and the redundancy measuring member; and a connector supplying power to the main measuring member and the redundancy measuring member, and transmitting the measurement values respectively measured by the main measuring member and the redundancy measuring member to the controller. The power supplied to the main measuring member and the redundancy measuring member is dualized and is independently supplied to the main measuring member and the redundancy measuring member through the connector. Therefore, cost can be reduced.

    본 발명의 차량용 토크 센서 장치는 로터부와 스테이터부의 상대 회전 변위에 따라 자기장의 변화량을 측정하는 메인측정부재; 로터부와 스테이터부의 상대 회전 변위에 따라 자기장의 변화량을 측정하는 리던던시 측정부재; 메인측정부재와 리던던시 측정부재의 측정값 중 적어도 하나를 통해 출력축의 회전을 보조하기 위한 모터 토크를 산출하는 제어기; 및 메인측정부재와 리던던시 측정부재에 전원을 공급하고 메인측정부재와 리던던시 측정부재에서 각각 측정된 측정값을 제어기에 전달하는 커넥터를 포함하고, 메인측정부재와 리던던시 측정부재에 공급되는 전원은 이중화되어 커넥터를 통해 메인측정부재와 리던던시 측정부재에 독립적으로 공급되는 것을 특징으로 한다.
