Vehicle infrastructure -- communication to support driver assistance systems

TL;DR

This paper discusses vehicle-to-infrastructure communication using IEEE 802.11p to enhance driver assistance systems by providing additional data and support through roadside units, complementing vehicle-to-vehicle communication.

Contribution

It highlights the development of a unified protocol stack for C2X communication and the role of roadside units in supporting driver assistance systems.

Findings

IEEE 802.11p is the standard for C2X communication.

Roadside units expand vehicle capabilities with additional data.

Unified protocol stack is being developed for effective communication.

Abstract

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.
