The present invention relates to a technique for improving robustness and responsibility of a centering function by performing a centering operation by using an electromagnet structure. According to the present invention, disclosed is a rear wheel steering device for a vehicle, comprising: a rear wheel steering cylinder installed between a rear axle and a rear wheel, linearly moved with a piston connected to the rear wheel, and provided to be an electromagnet by a coil and a core such that movement of the piston is limited in a rear wheel steering angle neutral position; and a controller for controlling supply of a current to the coil when a condition for maintaining neutrality of the rear wheel steering angle is satisfied.

    본 발명은 전자석 구조를 활용하여 센터링 작동을 수행함으로써, 센터링기능의 강건성 및 응답성을 향상시키는 기술에 관한 것으로, 본 발명에서는, 리어액슬과 후륜 사이에 설치되고, 후륜과 연결된 피스톤이 직선 이동되며, 코일과 코어에 의해 전자석이 되는 구조가 마련되어 후륜 조향각 중립 위치에서 피스톤의 움직임을 제한하도록 구성된 후륜조향실린더; 후륜 조향각 중립 유지조건 만족시, 상기 코일에 전류를 인가하도록 제어하는 제어기;를 포함하여 구성되는 차량용 후륜 조향장치가 소개된다.
