道路状态传感是实现自动驾驶的关键技术之一。高水平的自动驾驶汽车需要高实时性和高粒度的道路状态信息，以便在任何道路条件下，甚至在冬季的冰雪路面上安全驾驶。获取车辆运行点当前道路状态的方法有多种，但车辆需要一些方法来与其他车辆或路边单元交换道路状态信息。提出了一种面向道路状态信息交换的车联网无线通信系统。设计了一种与其他车辆进行道路状态信息交互的系统。在我们的设计中，建议的系统根据信号或数据类型切换最佳的无线链路。我们评估我们的基本系统设计的V2V无线通信在真实的道路环境。我们测量了路边单元和车辆之间的基本网络性能，移动车辆的实际速度。实验结果表明，该方法在实际道路交通中也具有足够的网络性能。
Road state sensing is one of essential technology to realize autonomous driving. High-level autonomous vehicle requires road state information with highly realtime and granularity in order to drive itself safely in any condition of road even snowy or icy road in winter. There is several methods to obtain current road state of vehicle running point, however vehicle requires some methods to exchange road state information among other vehicles or roadside units. This work proposes a Vehicle-to-Everything (V2X) wireless communication system which is oriented to exchange road state information. We designed the system for mutual exchanging road state information with other vehicles. In our design, proposed system switches the best wireless link according to signal or type of data. We evaluate our basic system design for V2V wireless communication in real road environment. We have measured basic network performance between roadside unit and vehicle which moves actual velocity of vehicle. The result suggests our method has enough network performance even in realistic road traffic.
