自动驾驶汽车设计有多种类型的车载传感器，并依赖于从车辆外部传递的多种类型的信息。为了传递这些信息，车联网（V2X）是实现互联汽车的基本技术要素。由于这些车辆需要通过增加传感器或输出数据的数量而产生的更大量的数据，因此还需要更高数据速率的无线通信。到目前为止，我们已经获得了基于IEEE 802.11ac标准的V2X通信的性能评估结果。然而，结果表明，由于硬件配置的限制，一些瓶颈。本文报告了基于IEEE 802.11ac无线局域网（WLAN）的V2X无线网络的性能评估。我们重新考虑了系统配置，可以解决这些硬件限制。通过实际道路环境下的性能评估，V2R通信与以前的配置没有显著差异。在V2V通信方面，我们已经确认了车辆间通信之间端到端性能的部分改进。
Autonomous driving vehicle is designed with multiple types of onboard sensor and depended on delivered multiple types of information from outside of the vehicle. In order to deliver these information, vehicle-to-everything (V2X) is an essential technical element to realize connected car. Since these vehicles require larger amount of data which are generated by increasing of number of sensors or output data, higher data rate wireless communication is also required. So far we have already obtained a result of performance evaluation for IEEE 802.11ac standard based V2X communication. However, the result suggested some bottlenecks due to hardware limitation of the configuration. This paper reports performance evaluation on V2X wireless network over IEEE 802.11ac wireless LAN (WLAN). We have reconsidered the system configuration which can solve those hardware limitations. Through the performance evaluation at actual road environment, V2R communication has no significant difference to previous configuration. On V2V communication, we have confirmed a part of improvement for the end-to-end performance between inter-vehicle communications.
