Abstract
Description
카메라 비젼을 이용한 주차 보조 시스템에서 액셀레이터 포지션 센서와 전자 주차 브레이크 제어를 이용하여 충돌을 방지하는 방법에 있어서,
제1영역 감지 후 장애물 영역이 증가하는 상태인지를 판단하는 제1단계와; 상기 제1단계에서 제1영역 감지 후 장애물 영역이 증가하는 상태이면 제1영역만큼 액셀 듀티값을 감소하는 명령을 수행하고, 장애물 영역이 증가하는 상태가 아니면 경고를 발생하는 제2단계와; 상기 제2단계에서 경고가 발생되는 상태에서 제2영역 감지 후 장애물 영역이 증가하는 상태인지를 판단하는 제3단계와; 상기 제3단에서 제2영역 감지 후 장애물 영역이 증가하는 상태이면 제2영역만큼 액셀 듀티값을 감소하는 명령을 수행하고, 장애물 영역이 증가하는 상태가 아니면 제3영역 감지 후 장애물 영역이 증가하는 상태인지를 판단하는 제4단계와; 상기 제4단계에서 장애물 영역이 증가하는 상태이면 제3영역만큼 액셀 듀티값을 감소하는 명령을 수행하며, 전자 주차 브레이크를 작동시키는 제5단계와; 차량이 충돌 영역을 회피한 상태인지를 판단하여, 충돌 영역을 회피하지 않은 상태이면 전자 주차 브레이크의 작동을 지속적으로 유지하고 충돌 영역을 회피한 상태이면 상기 제1단계로 리턴하는 제6단계를 포함하는 것을 특징으로 한다.
상기 S116의 판단에서 장애물 영역이 증가하는 상태이면 제어부는 제3 영역(20%) 만큼 액셀 듀티값을 감소하는 명령(-20%)을 수행한다(S118).
그러나, S116의 판단에서 장애물 영역이 증가하지 않는 상태이면 상기 S110의 단계로 리턴된다.
