Abstract
본 발명은 제동시에 후방차량과의 거리에 따라 제동등의 광도가 자동으로 조절되는 자동차의 제동등 광도 자동조절장치에 관한 것이다.The present invention relates to a brake light intensity automatic control device for a vehicle in which the brightness of the brake light is automatically adjusted according to the distance to the rear vehicle at the time of braking.
본 발명에 따르면, 브레이크페달을 조작시킴에 따라 스위치온되어 전원을 접속하는 제동등스위치와, 상기 제동등스위치의 턴온에 의해 후방차량으로 초음파를 발사하는 송신기 및 반사파를 감지하는 수신기로 이루어진 초음파센서와, 상기 초음파센서에서 초음파를 송/수신한 시간차이에 의해 후방차량과의 거리를 감지하는 거리판별부와, 상기 거리판별부의 출력신호에 따라 상기 제동등스위치로부터 공급되는 전압을 달리하여 제동등으로 공급하여 상기 제동등의 광도를 조절하는 제동등구동부로 구성된 것을 특징으로 하는 자동차의 제동등 광도 자동 조절장치가 제공된다.According to the present invention, an ultrasonic sensor comprising a brake light switch that is switched on by operating the brake pedal to connect a power source, a transmitter that emits ultrasonic waves to a rear vehicle by turning on the brake light switch, and a receiver that detects a reflected wave; The distance detecting unit detects the distance to the rear vehicle by the time difference transmitted / received by the ultrasonic sensor and the voltage supplied from the brake light switch according to the output signal of the distance discriminating unit is supplied to the brake lamp. There is provided a brake light intensity automatic control device for a vehicle, comprising a braking light driving unit for adjusting the brightness of a brake light.
