Enhanced Decentralized V2V Communications Leveraging the Potential of Automotive RADAR

The widespread adoption of Cooperative Automated Driving (CDA) in transportation systems is growing rapidly. Meeting the extensive communication requirements, ensuring reliability, cybersecurity, and safety for such systems pose significant challenges. One major hurdle is the establishment of robust communication protocols to ensure seamless, low latency and secure data exchange between vehicles and various elements of the transportation infrastructure. Achieving interoperability among diverse vehicle types, brands, and communication standards is another significant challenge. Furthermore, ensuring the reliability and low-latency communication necessary for safety-critical applications demands sophisticated technologies. Leveraging the existing array of sensors and processors found in modern vehicles could be highly beneficial in addressing these challenges. This proposal specifically focuses on this challenge, particularly exploring how existing RADAR systems can be utilized to establish secure, reliable and low cost communications between vehicles. This low-latency communication link proves highly advantageous in safety-critical applications, particularly where traditional Vehicle-to-Cloud (V2C) systems face challenges due to extended processing times and communication delays between vehicles and the cloud, and internal to cloud networks. This innovation could unlock significant possibilities for enabling real-time communication in safety-critical applications like Cooperative Collision Warning System (CCWS), Cooperative Maneuvering and Over-the-Air (OTA) Software Update.
