According to another aspect of the present invention, there is provided a method of automatically adjusting a rear taillight luminance of a vehicle, the method comprising: selecting an automotive rear lighting luminance automatic adjustment operation through an ON / OFF switch; Determining whether the vehicle is traveling, if the automatic rearlight brightness adjustment operation is selected to be ON; Determining whether the vehicle is traveling while exceeding a set speed; Determining whether a distance from the rear vehicle is within a set distance in a traveling state when the vehicle exceeds the set speed; And automatically starting the rear taillight when the distance from the rear vehicle is within the predetermined distance. Preferably, after the start of the rear taillight automatic adjustment operation, the operating state is maintained until the vehicle falls below the set speed or the distance from the rear vehicle exceeds a predetermined distance. According to another aspect of the present invention, there is provided an apparatus for automatically adjusting a rear taillight of a vehicle, the apparatus comprising: a speed sensor for sensing a speed of a driver or a passenger vehicle; A distance sensing unit for sensing a distance to the rear vehicle; A rear taillight driver for starting / stopping the rear taillight automatic adjustment operation and automatically adjusting the brightness of the rear taillight; Wherein the control unit controls the speed sensing sensor to measure the speed of the passenger vehicle and measures the distance to the rear vehicle by controlling the distance sensing unit so that the speed of the vehicle exceeds the set speed, And a controller for controlling the rear taillight driver to automatically adjust the brightness of the rear taillight if the distance is within a set distance.

Preferably, after starting the rear taillight automatic adjustment operation, the control unit may maintain the operating state until the speed of the vehicle falls below the set speed or the distance from the rear vehicle exceeds a predetermined distance And controls the rear taillight drive section to drive the rear taillight drive section.

Preferably, the distance sensing unit is a V2V (Vehicle to Vehicle) technology or a sensor. When the V2V technology is used, the distance measured by the inter-vehicle communication technology is utilized. In the case of using the sensor, the sensor is any one of an ultrasonic sensor, an infrared sensor, and a Doppler sensor.

Preferably, the rear taillight driver controls a duty ratio change by a PWM control method.

Preferably, the electronic apparatus further includes an ON / OFF selection switch for selectively interrupting the power supplied to the control unit to selectively shut off the automatic adjustment operation of the rear taillight luminance of the automobile.

According to the present invention, when the rear vehicle approaches within a set distance during high-speed traveling of the vehicle, the rear light is emitted with a high luminance as the proximity distance approaches, the speed of the vehicle becomes less than the set speed, The brightness of the rear taillight is gradually lowered to the original brightness according to the distant distance. Therefore, when the vehicle approaches the vehicle within a safe distance at the time of high-speed driving, It is possible to secure a safe distance for warning against unexpected situations, thereby providing an advantage of preventing unexpected collision or collision beforehand.
