- 자동차에 장착된 카메라로부터 입력된 영상신호를 처리하기 위한 영상처리 프로세서, 조향 휠의 회전각을 측정하는 조향각 센서, 상기 자동차의 속도를 측정하는 차속 센서 및 조향 축의 토크를 측정하는 토크 센서를 포함하는 시스템에서 상기 카메라의 상기 영상신호를 이용하여 상기 자동차에 조향 제어를 제공하는 방법에 있어서,(a) 상기 영상처리 프로세서에서 상기 카메라로부터 입력되는 상기 영상신호를 처리하여 생성한 차선폭을 절반으로 나눈 값인 L 값과 상기 자동차에서 가장 가까운 어느 일측의 상기 차선을 기준으로 상기 자동차의 중심과의 거리인 La 값을 주기적으로 수신하는 단계;(b) 상기 조향각 센서, 상기 차속 센서 및 상기 토크 센서에서 측정한 센싱값을 주기적으로 수신하는 단계;(c) 상기 토크 센서로부터 입력되는 입력 토크와 비교하기 위한 기준이 되는 τ 와 상기 토크 센서로부터 입력되는 상기 입력 토크를 비교하여 상기 입력 토크가 상기 τ 미만인지 여부를 확인하는 단계;(d) 상기 단계 (c)에서 상기 입력 토크가 상기 τ 미만이라고 판단한 경우 상기 영상처리 프로세서가 주기적으로 생성하여 송신하는 상기 La 값을 수신하여 기존의 상기 La 값을 값으로 생성한 후 새로 수신한 상기 La 값을 갱신한 후 가 상기 L 값 미만인지 여부를 확인하는 단계;(e) 상기 단계 (d)에서 상기 가 상기 L 값 미만이라고 판단한 경우 상기 자동차가 상기 가 상기 L 값 미만인 상태에서 지정된 시간 T보다 긴 시간 동안 주행하는지 여부를 확인하는 단계; 및(f) 상기 단계 (e)에서 상기 가 상기 L 값 미만인 상태에서 지정된 상기 시간 T보다 긴 시간 동안 주행한다고 판단한 경우 상기 자동차의 조향 휠의 중점을 파악하고 조향 제어를 수행하는 단계를 포함하는 것을 특징으로 하는 카메라의 영상신호를 이용하여 자동차에 조향 제어를 제공하는 방법.
- 제 1 항에 있어서,상기 단계 (c) 이후에,(c1) 상기 입력 토크가 상기 τ 이상이라고 판단한 경우 조향 장치를 구동하여 운전자의 조향을 보조해주는 것을 특징으로 하는 카메라의 영상신호를 이용하여 자동차에 조향 제어를 제공하는 방법.
