V2X Communication Requirements for Autonomous Vehicles

Abstract. Vehicle to Everything (V2X) communication has been the topic of much research, development, standards, and testing activity over the last two decades. The focus of most of these activities, including definition of the performance requirements, has been Advanced Driver Assistance Systems (ADAS), which assumes a human is in control of the vehicle. Many companies are now working on autonomous vehicle (AV) technology, where the vehicle is capable of fully automated driving in many (and eventually all) scenarios. While much of the work on AV systems has been on sensors and artificial intelligence, V2X communication is expected to play an important role in connecting an AV to other vehicles as well as infrastructure, especially when vehicles cannot detect each other using sensors. The requirements for V2X in AV systems are different from the requirements for V2X in ADAS, since the human is no longer “in the loop.” In this panel, the group will address the new use cases for V2X in AV and the additional requirements for V2X features and performance that are needed to support this rapidly evolving technology.
