Abstract
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.
