Speaker: Bernd Lehmann This talk is about Vehicle2Vehicle (V2V) communication in Europe and in the U.S. Next to the introduction of some requirements for V2V communication, the basic approaches of V2V communication based on IEEE 802.11p are presented. This includes an introduction to communication stack, concepts of message dissemination, message contents, privacy & security issues and an outlook to further developments. Modern vehicles have several advanced driver assistant systems (ADASs). This is the beginning of the full automation of the driving task. Vehicle manufacturers already showed first fully automated prototypes but a lot of challenges have to be addressed until such systems will be commercially available. One challenge is to provide the necessary information for the self-driving vehicle to make the right driving decisions. V2V communication is one possible technology to provide this information. The proposed talk is an introduction to the state of the art of V2V communication based on IEEE 802.11p. This talk is a technical introduction to Vehicle2Vehicle communication. It will introduce the basic concepts of V2V technology and provides references to documents of the standardization. The talk will consist of the following parts: Motivation: The talk starts by describing the scope and possible applications of V2V communication focusing on the use-case of the “Electronic Emergency Break Light”. What is more, V2V communication will be compared to traditional on-board sensors like Lidar or Radar. Basic concepts: The state of the art concepts of V2V communication based on IEEE 802.11p and its differences compared to consumer WiFi will be discussed in this section. Furthermore, the existing concepts and standards developed in both Europe and the U.S. will be compared, with a special focus on the differences between the two approaches. In summary, the following questions will be addressed: • What are the approaches for V2V communicat
