Mercedes on V2X communication

mercedes v2x

Cars are nowadays able to collect a great deal of information about the current driving situation, as the numerous sensors, cameras and control units for the dynamic and assistance systems can register e.g. poor weather conditions just as well as sudden braking and avoiding manoeuvres, or broken-down vehicles on the road.

Mercedes engineers have been working on “Interactive Vehicle Communication” as a technology of the future for more than seven years. The ESF 2009 safety concept vehicle demonstrates the current status of this research: this Mercedes can automatically recognise an approaching police car, for example, and warn its driver by showing a symbol in the display.It is also possible to send and receive warnings of bad weather or obstacles in the road.
The exchange of data between vehicles is via so-called “ad hoc” networks, connections that are spontaneously formed between the vehicles over short distances. These wireless local area networks (WLANs) are self-organising, and require no external infrastructure. Transmission and reception is at a frequency of 5.9 gigahertz, over a distance of up to 500 metres. In fact the achievable communication range is much greater, as oncoming vehicles pass the messages on.
