Abstract
본 발명은 졸음운전 경보장치 및 그 제어방법에 관한 것으로서, 상세하게는 운전자의 운전상황을 윈드실드 상단에 장착된 CCD 카메라로 촬영하여 졸음운전이 감지되면 순차적 또는 동시에 경보음, 운전석을 진동시켜 경보하고, 상기의 경보에도 불구하고 계속하여 졸음운전이 감지될 경우에는 자동으로 브레이크를 작동시켜 자동차를 정지시킴으로써 졸음운전으로 인한 사고를 미연에 방지할 수 있고, CCD 카메라에 광센서와 램프를 구비하여 야간에도 양질의 화상을 얻을 수 있는 졸음운전 경보장치와 CCD 카메라로 촬영한 화상데이터로부터 졸음운전을 감지하여 판단함에 있어서 눈을 감고 있는 시간과 고개를 좌측 또는 우측으로 기울이고 있는 시간을 함께 측정하여 기준값과 비교함으로써 졸음운전판단의 정확도를 높인 졸음운전 경보방법이다.More particularly, the present invention relates to a drowsy driving alarm apparatus and a control method thereof. More particularly, the present invention relates to a drowsiness driving alarm apparatus and a control method thereof, If the drowsy operation is detected in spite of the above alarm, the brakes are automatically operated to stop the vehicle, thereby preventing the accident caused by the drowsy operation. The CCD camera is provided with a light sensor and a lamp In the drowsiness driving alarm device capable of obtaining a good image at night and the drowsiness driving sensed from the image data photographed by the CCD camera, the time of closing the eyes and the time of tilting the head to the left or right side are measured together, To thereby improve the accuracy of the drowsy driving judgment.
