본 발명은 후륜 조향 제어 장치에 관한 것으로서, 조향휠의 조향각을 검출하는 조향각 센서, 차량의 차속을 검출하는 차속센서, 조향축에 인가되는 조향토크를 검출하는 조향토크 센서, 및 상기 조향각 센서에 의해 검출된 조향각으로부터 전륜각 및 조향각속도를 산출하고, 상기 조향토크 센서에 의해 검출된 조향토크 및 상기 산출된 조향각속도 중 하나 이상과, 상기 차속센서에 의해 검출된 차속에 따른 동역상 게인에 근거하여 후륜 조향 반응성 향상을 위한 후륜각 보상인자를 산출하며, 상기 전륜각, 상기 후륜각 보상인자 및 상기 동역상 게인에 기초하여 목표 후륜각을 산출하는 제어부를 포함하는 것을 특징으로 한다.

    An apparatus for controlling rear wheel steering includes a steering angle sensor detecting a steering angle of a steering wheel; a vehicle speed sensor detecting a vehicle speed of a vehicle; a steering torque sensor detecting a steering torque applied to a steering shaft; and a control unit calculating a front wheel angle and a steering angle velocity from the steering angle detected by the steering angle sensor, calculating a rear wheel angle compensation factor for improving rear wheel steering responsiveness based on at least one of the steering torque detected by the steering torque sensor and the calculated steering angle velocity and a same/opposite phase gain depending on the vehicle speed detected by the vehicle speed sensor, and calculating a target rear wheel angle based on the front wheel angle, the rear wheel angle compensation factor and the same/opposite phase gain.
