队列驾驶是智能交通系统（ITS）应用之一，旨在改善道路交通安全、道路容量和环境影响。车队中车辆的协调依赖于可靠的实时通信。除了基于射频（RF）的技术，如专用短距离通信（DSRC）和蜂窝V2X (C-V2X)，视距（LOS）技术，如车载VLC （V-VLC）被认为是建立必要的通信链路。在之前的工作中，我们研究了V-VLC的LOS行为，发现在弯曲道路上行驶时，相邻车道上的车辆或跟随车辆造成的干扰是不可忽略的。在本文中，我们研究了这种干扰对队列应用的影响。作为解决方案，我们进一步建议使用现代自适应前置照明系统（afs）的空间多路复用。这种矩阵灯的单个led的窄光束大大降低了干扰水平，使通信更加健壮和可靠。
Platooning is one of the Intelligent Transportation System (ITS) applications that is envisioned to improve both road traffic safety as well as road capacity and environmental impact. The coordination of vehicles in a platoon depends on reliable real-time communication. In addition to Radio Frequency (RF)-based technologies such as Dedicated Short Range Communications (DSRC) and Cellular V2X (C-V2X), Line Of Sight (LOS) technologies such as Vehicular VLC (V-VLC) are considered to establish the necessary communication links. In previous work, we investigated the LOS behavior of V-VLC and found that there is a non-negligible amount of interference caused by cars on neighboring lanes or by following cars when driving on a curved road. In this paper, we investigate the impact of such interference on platooning applications. As a solution, we further suggest the use of spatial multiplexing using modern Adaptive Front-Lighting Systems (AFSs). The narrow beams of single LEDs of such matrix lights massively reduce the interference level and make the communication even more robust and reliable.
