Vehicle infrastructure -- communication to support driver assistance systems

The area of vehicle-to-infrastructure (C2I) communication has become an increasingly important area in the field of C2X communication in recent years. It is on the same level as vehicle-to-vehicle (C2C) communication and uses the same technologies and protocols. In today's research environment, the consensus is that IEEE standard 802.11p is used for communication. Based on this, the Car-2-Car Communication Consortium is developing a unified protocol stack for effective and efficient C2X communication. Roadside units (RSU) can be used to support driver assistance systems. Through targeted information processing and information distribution, they are intended to expand the vehicle's capabilities through additional data and also provide information that could not be made available through C2C communication alone.
