본 발명은 안전 운행을 위한 자동차 브레이크등 제어시스템에 관한 것으로, 브레이크를 밟는 상태에 따라 브레이크등(LED등)의 색상 또는 점멸주기를 다르게 출력하여 긴급한 상황인지 여부를 뒷 차가 인지할 수 있도록 하는 안전 운행을 위한 자동차 브레이크등 제어시스템에 관한 것이다. 따라서 본 특허는 브레이크를 밟는 상태에 따라 브레이크등(LED등)의 색상 또는 점멸주기를 다르게 출력하여 긴급한 상황인지 여부를 뒷 차가 인지할 수 있도록 하는 효과가 있다.The present invention relates to a vehicle brake light control system for safe driving, which outputs a different color or blinking cycle of a brake light (LED light) according to the state of stepping on the brake so that the following vehicle can recognize whether or not it is an emergency situation. It relates to an automobile brake light control system for operation. Therefore, this patent outputs the color or flashing cycle of brake lights (LED lights) differently according to the state of stepping on the brakes, so that the following car can recognize whether or not it is an emergency situation.

본 발명은 브레이크를 밟는 상태에 따라 브레이크등(LED등) 의 색상을 다르게 출력하여 긴급한 상황인지 여부를 뒷차가 인지할 수 있도록 한다.The present invention outputs different colors of brake lights (LED lights) according to the state of stepping on the brakes so that the vehicle behind can recognize whether or not it is an emergency situation.

(예) 강력한 빨강<-> 중간 빨강<->연한 빨강 스타일로 다른 색상을 출력 (Example) Output different colors in strong red<-> medium red<->light red style

또는 브레이크 등의 점멸주기를 다르게 하여 출력한다.Alternatively, it is output by changing the flashing cycle of the brake light.

(예) 긴급 브레이크(점멸주기 아주 짧게) , 급 브레이크(점멸주기 짧게), 브레이크(점멸주기 보통) (Example) Emergency brake (very short flashing cycle), emergency brake (short flashing cycle), brake (normal flashing cycle)

다시 상황이 변한 경우(브레이크에서 발을 뗀 경우) 색상을 상황에 맞게 조절한다.If the situation changes again (take your foot off the brake), adjust the color to suit the situation.

한편, 상기 색상과 점멸주기는 연동하여 제어할 수 있는 것으로, 야간 운행시 또는 우천시는 제어부는 색상 제어모드로서 색상을 제어하고, 터널 등에서는 불빛이 잘 보이지 않으므로, 점멸주기 모드로서 점멸주기를 제어한다. 곧 제어기는 GPS모듈, 네비게이션에 의해 차량의 현재 위치가 터널인 경우 점멸주기 모드로 동작케 한다.On the other hand, the color and the blinking cycle can be controlled in conjunction with each other, and the control unit controls the color as a color control mode during night driving or in rainy weather, and controls the blinking cycle as a blinking cycle mode because the light is not easily visible in a tunnel or the like. do. Soon, the controller operates in the blink cycle mode when the current location of the vehicle is in the tunnel by means of the GPS module and navigation.

한편, 비상등을 켤 경우에는 상기 색상 제어모드와 점멸주기 모드를 동시에 동작시킨다.Meanwhile, when the emergency light is turned on, the color control mode and the flashing cycle mode are simultaneously operated.

따라서 본 발명은 브레이크를 밟는 상태에 따라 브레이크등(LED등)의 색상 또는 점멸주기를 다르게 출력하여 긴급한 상황인지 여부를 뒷 차가 인지할 수 있도록 하여 안전운행을 할 수 있는 현저한 효과가 있다.Therefore, the present invention has a remarkable effect of enabling safe driving by outputting the color or flashing cycle of brake lights (LED lights) differently according to the state of stepping on the brakes so that the car behind can recognize whether or not it is an emergency situation.
