The present invention provides a rear wheel steering control device which comprises: a turning state estimation unit estimating a turning state by acquiring steering angle information from a steering angle sensor to calculate required steering speed from the steering angle information; a normal state lateral acceleration prediction unit predicting a normal state lateral acceleration appropriate for the required steering speed when the required steering speed is at least a speed threshold value; and a rear wheel steering angle calculation unit calculating a rear wheel steering angle according to an steering angle and the lateral acceleration. According to the present invention, yaw rate-roll angular delay time is reduced by controlling rear wheel steering during steering of a driver, thereby providing a sense of unity in turning to the driver.

    본 발명은 조향각 센서로부터 조향각 정보를 획득하여, 상기 조향각 정보로부터 요구 조향속도를 연산하여 선회상태를 추정하는 선회상태 추정부, 상기 요구 조향속도가 속도 임계값 이상인 경우, 상기 요구 조향속도에 맞는 정상상태 횡가속도를 예측하는 정상상태 횡가속도 예측부 및 상기 조향각 및 상기 횡가속도에 따른 후륜 조향각을 계산하는 후륜조향각 계산부를 포함하는 후륜 조향 제어 장치로서, 본 발명에 의하면, 운전자 조타시 후륜 조향을 제어하여 요 레이트-롤 각 지연시간을 줄임으로써 운전자에게 선회 일체감을 제공할 수 있다.
