| At a time when on-board technologies are trying to out-do each other in terms of inventiveness, the time has also come to think about the next large scale development to affect the world of the car. This will enable vehicles to evolve by taking account of each other, according to information they will be able to exchange autonomously! A vehicle whose ABS or ESP detects a patch of ice will thus be able to communicate the fact to the cars following it? an area of dense traffic would be able to be avoided. An accident would be instantaneously signalled by the vehicles involved?
This incredible communications challenge will only come about if there is a consensus between all manufacturers. Nine of them (Audi, BMW, Fiat, Honda, Mercedes, Opel, Renault, Volkswagen and Volvo) have currently met in the context of the Car2Car organisation to broach this theme. Car2Car is counting on a standard communications protocol which would use a Wifi network. By equipping a vehicle with emitting and receiving antenna, it would become communicative over a range of 50 metres. This seems a little small, which is why Car2Car is also envisaging being able to count on hotspots.
