밝기 조절 및 가시광 무선통신이 가능한 차량 후미등 제어 방법이 개시된다. 본 발명에 따른 차량 후미등 제어 방법은 차량의 운행정보 데이터를 생성하는 단계; 상기 차량의 후방에 설치되는 광원의 밝기를 제어하는 밝기 제어값을 생성하는 단계; 및 상기 운행정보 데이터 및 상기 밝기 제어값에 기초하여 상기 광원을 제어하는 펄스의 단위 펄스 구간 내의 펄스 위치 및 펄스 폭을 제어한다.

    An apparatus and method for controlling the taillight of a vehicle are disclosed. The apparatus includes a visible light wireless communication data generation unit, a brightness control unit, a variable pulse position modulation (VPPM) signal generation unit, and a light source. The visible light wireless communication data generation unit generates information about the operation of a vehicle. The brightness control unit generates a brightness control value that is used to control the brightness of a light source installed at the tail of the vehicle. The variable pulse position modulation (VPPM) signal generation unit controls a pulse position and a pulse width within a unit pulse section of a pulse that controls the light source based on the information about the operation of the vehicle and the brightness control value.
