The present invention relates to algorithm for preventing drowsy driving of drivers. An expressway is a place where drivers performs drowsy driving most frequently. On an expressway, a driver inevitably holds a handle and steps on an accelerator for a long time. Accordingly, the algorithm for preventing drowsy driving of drivers is derived from naturally decreased pressure applied to a handle and an accelerator during drowsy driving. Conventional products rather have a bad influence on driving because of oppressive and compulsory blocking of drowsy driving of a driver. The algorithm for preventing drowsy driving of drivers mainly consists of a pressure sensor, a main processor, and a vibrator. When the main processor determines drowsy driving of a driver, and gives instructions regarding actions in accordance with the determination, an internal devices safely and fairly perform the actions to prevent the drowsy driving of the driver. The pressure of an accelerator and a handle is calculated to input averages thereof for a time period set by the driver, and the individual pressure averages are continuously accumulated. If pressure lower than the averages continues for two seconds, the main processor determines that the driver is driving while drowsy. Accordingly, a vehicle window is opened, vibration is generated on a seat and the handle, and a noise is made sequentially, to wake up the driver. Since a last situation may be dangerous, emergency blinkers are turned on. The main processor is connected with an automobile radio to receive weather information, and outputs a warning announcement in accordance with the weather information.

    본 발명은 운전자들의 졸음운전을 막기위한 알고리즘이다. 운전자가 졸음운전을 가장 많이 하는 곳은 고속도로이다. 고속도로에서는 불가피하게 장시간동안 핸들을 잡고 액셀러레이터를 밟고 있는데, 졸음운전을 하게 되면 저절로 핸들과 액셀러레이터에 전해지는 압력이 줄어드는 점에서 착안하였다. 본래 나온 제품들은 운전자의 졸음운전을 강압적이고 강제적으로 막아 오히려 운전에 악영향을 미칠 수 있었다. 크게 압력센서와 메인 프로세스, 진동장치로 이루어진다. 메인프로세스에서 운전자의 졸음운전 판단과 그에따른 행동을 지시를 내리게 되면, 각 내부에 장치들은 그 행동들을 안전하고 공정하게 실행하여 운전자의 졸음운전을 방지한다. 운전자가 설정한 날짜동안 액셀러레이터와 핸들에 압력을 계산하여 평균을 입력하고, 그 뒤 계속해서 개인의 압력 평균을 쌓아간다. 만약 평균보다 낮은 압력이 2초간 계속될 경우, 운전자는 졸음운전을 하고 있다고 판단하여 순차적으로 차창을 열고, 시트와 핸들에 진동을 일으킨 뒤, 소음을 내어 운전자를 깨운다. 마지막 상황은 위험할수도 있는 상황이므로 비상깜빡이를 켜게 된다. 메인프로세스는 자동차의 라디오와 연동되어 기상정보를 받아들이고 그에 따른 경고 멘트를 출력한다.
