Abstract

본 발명은 야간 고속 운행시 앞, 뒤 차량과의 안전 거리를 유지하기 위해 설정된 거리치보다 작을 경우에는 비상등 점멸 및 경고음을 울려서 운전자의 주의를 상기 시 키는 데에 그 목적이 있다.The present invention has an object to remind the driver of the warning by flashing the emergency light flashing and a warning sound when it is smaller than the distance value set to maintain a safe distance with the front and rear vehicles at night high speed driving.

종래 자동차의 차간 거리 유지 방법은 야간고속운행시 주간고속운행시보다 앞, 뒤 차량과의 거리에 대한 감이 다르기 때문에 운전자가 차간 거리를 잘못 판단하여 사고를 유발할 수 있는 문제점이 있었다.In the conventional method of maintaining the distance between cars, there is a problem that a driver may cause an accident by incorrectly judging the distance between cars because the sense of distance from the front and rear vehicles is different from that of the daytime high speed driving at night high speed driving.

이것을 해결하기 위해, 본 발명은 운전자가 주행을 하기 위하여 이그니션 스위치를 온시킨 후 야간에 헤드 램프 스위치를 점등하고 운행을 하고 있을 때 차량 속도 센서로부터 자기 차량의 현재 주행 속도를 검출하는 제 1과정과, 제 1과정으로부터 출력된 현재 차량속도치가 기설정치(100㎞/h)보다 크면 프런트/리어 거리 센서를 구동하여 앞, 뒤 차량과의 거리를 검출하는 제 2과정과, 제 2과정으로부터 검출된 거리값과 기설정치(80m)를 비교하고 그 결과 앞 차량과의 거리가 기설정치보다 작으면 릴레이를 구동하여 비상등을 점멸하고 경고음을 울리게 되고 또한 뒤 차량과의 거리값과 기설정치 (80m)를 비교하여 기 설정치보다 작으면 릴레이를 구동하여 비상등을 점멸하고 경고음을 울리게 되는 제 3과정으로 이루어진다.In order to solve this problem, the present invention provides a first process of detecting the current driving speed of the vehicle from the vehicle speed sensor when the driver turns on the ignition switch to drive the vehicle and turns on the head lamp switch at night. If the current vehicle speed value output from the first process is greater than the preset value (100 km / h), the second process of detecting the distance between the front and rear vehicles by driving the front / rear distance sensor and the second process detected from the second process. Compare the distance value with the preset value (80m) and as a result, if the distance from the front vehicle is smaller than the preset value, the relay will be activated to flash the emergency light and sound a warning. In comparison, if it is smaller than the preset value, a third process is performed in which the relay is driven to flash the emergency light and sound an alarm.
