The present invention relates to a variable lateral angle control method of an automobile to which a rear wheel steering system is applied. The present invention comprises: a first step of calculating a first steering angle ratio value corresponding to a steering angle ratio of front wheels and rear wheels in a driver driving mode and calculating a second steering angle ratio value corresponding to the ratio of front wheel and rear wheel steering angles in an autonomous driving mode; a second step of calculating the rear wheel steering angle through an operation based on the second steering angle ratio value and comparing the rear wheel steering angle with a predetermined steering wheel steering (RWS) maximum steering angle; and a third step of determining one of the driver driving mode and the autonomous driving mode if it is determined that the rear wheel steering angle is smaller than the RWS maximum steering angle.

    본 발명은 운전자 주행모드에서 전륜과 후륜의 조향각 비율에 해당하는 제1조향각 비율 값을 계산하고, 자율 주행모드에서 전륜과 후륜 조향각 비율에 해당하는 제2조향각 비율 값을 계산하는 제1단계와 상기 제2조향각 비율 값에 의한 연산을 통해 후륜 조향각을 계산하고, 상기 후륜 조향각을 기설정된 리어 휠 스티어링(Rear Wheel Steering, RWS) 최대 조향각과 비교하는 제2단계 및 상기 후륜 조향각이 상기 RWS 최대 조향각 보다 작은 것으로 판단되면, 상기 운전자 주행모드 또는 상기 자율 주행모드 중 어느 하나의 운전모드를 판정하는 제3단계를 포함한다.
