Millimeter-Wave V2V Communications with Cooperative Perception for Automated Driving

The combination of automated driving based on onboard sensors and decisions and external interactions with the environments through wireless communication has great advantages over the conventional driving systems in terms of safety and reliability. High resolution dynamic maps, which contain the real time information of the driving environment obtained by the collection and fusion of external sensors, can improve the driving safety and reliability dramatically thanks to the additional information beyond the perceptions of the onboard sensors. In this paper, we analyzed the required amount of dynamic information to be exchanged for the cooperative perception in order to enable a new level of safe and reliable automated driving. The results confirm the indispensability of millimeter-wave communications in automated driving systems. In this paper, we focus on an analysis of the required amount of the dynamic information exchange from cooperative sensor perception to enable a new level of safe and automated driving. The results show the necessity of millimeter wave communications for automated driving systems.
