Abstract

본 발명은 크루즈 컨트롤시스템을 구비한 자동차에 관한 것으로, 자동차를 운행하는 중에 전방 차량과의 거리를 감지하여 크루즈 콘트롤러에 의해 스로틀 벨브의 개도를 조절하여 차량의 엔진속도를 자동으로 감속시켜 주어 충돌사고를 방지할 수 있도록 하는 자동차에서의 속도 제어 방법에 관한 것이다. 종래의 자동차에 구비된 크루즈 컨트롤시스템 기능만으로는 운전자가 고속도로 주행시 졸음등으로 전방 시야를 확보하고 있지 못한 상태에서 전방차량과의 안전거리를 유지하지 못하게 되는 경우에 충돌사고를 유발하게 되는 문제점이 있었다. 본 발명은 차량용 인스트루먼트 판넬(102)의 소정부위에 장착된 거리센서(101)를 구비하여 소정의 신호를 전자제어부(ECU)(211)에 보내면 전자제어부(ECU)(211)의 엔진제어부(217)가 스로틀 벨브(227)을 제어하여 엔진의 회전속도를 감속시킴으로써 자동차의 주행속도를 자동으로 감소시켜 주므로, 운전자가 졸음등으로 전방시야를 주의하지 못하는 상태에서 전방 차량과의 안전거리를 미확보함에 기인하여 발생되는 전방 차량과의 충돌사고를 미연에 방지할 수 있다.
