Solutions for Car2x / V2X

Car2x and V2X - these are the current keywords when it comes to the future of safety, efficiency and comfort in road traffic. And whether we talk about Car2x or V2x, we mean the same thing: integrating vehicles into a comprehensive data infrastructure that enables direct communication between vehicles (V2V: Vehicle to Vehicle) on the one hand and infrastructure (V2I: Vehicle to Infrastructure) on the other.

Information such as speed, position or status/condition, which is based on the driver's ability to assess when driving conventionally, can now be exchanged and processed directly.

Challenges

The high degree of networking within the vehicle as well as with its environment brings with it a number of new challenges:

  • the use of IEEE 802.11p
  • the parallel use of different technologies with data fusion (wireless, radar systems of different ranges, laser scanners, image processing systems, etc.).
  • a common time base in highly dynamic networks
  • the exchange of item data
  • process complex data structures and optional elements in coded application messages to make communication secure through signatures and encryption

Application Areas

The development of cooperative systems in the V2x or Car2x area brings decisive advantages when it comes to safety, efficiency and comfort in road traffic. Thus, intelligent telematics and driver assistance systems can be implemented, such as

  • traffic jam warnings,
  • construction site warnings,
  • intersection assistants,
  • electronic brake lights or
  • applications such as platooning, an electronically coupled convoy.

Functionality

Communication between vehicles or between vehicles and the infrastructure takes place via the WLAN standard IEEE 802.11p (ETSI ITS-G5 or IEEE 1609 WAVE). This is used to exchange Car2x-specific network and transport protocols with application messages attached to them. Examples of application messages are

  • the Cooperative Awareness Message (CAM) and
  • the Decentralized Environmental Notification Message (DENM) in Europe and
  • the Basic Safety Message (BSM) in the USA.

In order to ensure secure communication, signed packages (Secured Packets) must also be used.

Cooperations

CAR 2 CAR Communication Consortium

The CAR 2 CAR Communication Consortium (C2C-CC) is a non-profit association of European vehicle manufacturers, suppliers, research institutions and other partners.

The C2C-CC aims to increase road safety and efficiency through the use of cooperative Intelligent Transport Systems (ITS) through vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication.
