The present invention relates to an apparatus and a method for reducing judder of a driven vehicles steering wheel in a braking situation. Steering torque of a band reacting to vibration of the steering wheel is detected from steering torque sensed by a torque sensor to determine whether judder of the steering wheel occurs. When it is determined that the judder of the steering wheel occurs, a logic for reducing the judder of the steering wheel is performed by using rotation frequency of a vehicle wheel and an adaptive filter algorithm, improving the accuracy of detection of the occurrence of judder of the steering wheel and improving judder reduction performance to improve driving stability of the vehicle.

    본 실시예들은 주행 중인 차량의 제동 상황에서 발생하는 조향 휠의 저더를 저감하는 장치 및 방법에 관한 것으로서, 토크 센서에 의해 센싱된 조향 토크에서 조향 휠의 진동에 반응하는 대역의 조향 토크를 검출하여 조향 휠의 저더가 발생한 것인지 여부를 판별하며 조향 휠의 저더가 발생한 것으로 판별되면 차량 휠의 회전 주파수와 적응형 필터 알고리즘을 이용하여 조향 휠의 저더를 저감하기 위한 로직을 수행함으로써, 조향각의 변화량이 없거나 작은 경우에 발생하는 조향 휠의 저더도 감지하여 조향 휠의 저더 발생 감지의 정확도를 향상시키고 동시에 저더 저감 성능을 향상시켜 차량의 주행 안정성을 향상시킬 수 있도록 한다.
