Abstract

본 발명은 자동차의 전조등 각도 자동 조절방볍 및 장치에 관한 것으로서, 이는 야간 운전시에 자동차의 속도 및 앞차와의 거리를 자동으로 감지하여 자동차의 전조등 각도를 모터를 통해 자동으로 조절하여 불빛에 의한 상대방의 시각 장애를 유발시키지 않도록 하기 위한 것이다.The present invention relates to a method and apparatus for automatically adjusting the headlight angle of a vehicle, which automatically detects the speed and distance of the vehicle at night and automatically adjusts the headlight angle of the vehicle through a motor to adjust the headlight angle of the vehicle. This is to avoid causing visual impairment.

이와 같은 본 발명은 전조등이 온되어 있는가를 검색하는 단계와; 상기 검색한 결과 온되어 있으면 전조등 자동 조절키이가 온되었는가를 검색하는 단계와; 상기 검색한 결과 자동 조절키이가 온되었으면 차간거리를 감지하는 센서의 작동 범위내에 앞차가 존재하는가를 검색하는 단계와; 상기 검색한 결과 앞차가 존재하면 모터를 구동시켜 건조등 각도를 앞차의 범퍼에 고정시키는 단계와; 상기 센서의 작동 범위내에 앞차가 존재하지 않으면 자동차속도를 감지하여 판단하는 단계와; 상기 판단한 결과 자동차 속도가 빨라지면 전조등 각도를 상향으로, 속도가 느려지면 전조등 각도를 하향으로 조절하는 단계 이루어짐으로써 달성된다.Such a present invention comprises the steps of searching whether the headlight is on; Searching whether the headlight automatic control key is on if the search result is turned on; Searching whether the front vehicle exists within an operating range of a sensor for detecting a distance when the automatic adjustment key is turned on as a result of the search; Fixing the drying lamp angle to the bumper of the front vehicle by driving a motor if the front vehicle exists as a result of the search; Detecting and determining a vehicle speed if a front vehicle does not exist within an operating range of the sensor; The determination result is achieved by the step of adjusting the headlight angle upward when the speed of the car is increased, and the headlight angle downward when the speed is slowed.
