On the Needs and Requirements Arising from Connected and Automated Driving

Abstract

Future 5G systems have set a goal to support mission-critical Vehicle-to-Everything (V2X) communications and they contribute to an important step towards connected and automated driving. To achieve this goal, the communication technologies should be designed based on a solid understanding of the new V2X applications and the related requirements and challenges. In this regard, we provide a description of the main V2X application categories and their representative use cases selected based on an analysis of the future needs of cooperative and automated driving. We also present a methodology on how to derive the network related requirements from the automotive specific requirements. The methodology can be used to analyze the key requirements of both existing and future V2X use cases.

Adaptive control for reliable cooperative intersection crossing of connected autonomous vehicles

“…Note that the TTC threshold of 3 and 4 s is highly conservative for CAVs 43 . The average exposure time per vehicle meets the vehicle‐to‐everything communication safety latency requirements, ranging from 3 to 100 ms based on the latest 5G and C‐V2X communication protocols, guaranteeing performance reliability 44,45 . Therefore, the TTC results highlight the advantages of the proposed adaptive intersection crossing control in securing performance reliability.…”
