Vehicle-to-vehicle communication set to improve road safety

Car-2-Car can warn of approaching hazards, such as a motorcycle hidden from view by a truck.

The Car 2 Car Communication Consortium staged its first practical demonstration of the system’s capabilities in trials at the Opel test track at Dudenhofen, near Frankfurt in Germany. The European consortium, a collaboration between OEMs and open to suppliers and research organizations, aims to promote safety systems through vehicle-to-vehicle communications.

The non-profit organization aims to establish a European industry standard for wireless LAN communications between vehicles and roadside beacons. Members include Volvo Trucks, Audi, BMW, Daimler, Fiat, Honda, Opel, and Renault.

The use of Car-2-Car was shown using three potential hazard situations. In the first, a roadside beacon transmitted information about nearby road repairs. The messages included detailed information about the site such as the location and duration of the work.

In the second demonstration, a motorcycle and car are approaching a junction. The car driver cannot see the motorcycle because of an obstruction. A message is transmitted to the car to warn the driver of the approaching motorcycle and the motorcyclist receives a warning about the approaching car.

The third scenario showed the use of the Car-2-Car system to warn of an emergency vehicle approaching from behind. Other drivers are not always aware of an approaching emergency vehicle, even with flashing emergency beacons and sirens activated. The Car-2-Car system alerts drivers to the approaching vehicle and advises them to stop at the roadside until the vehicle has passed. In all three demonstrations, the communications system could help to avoid an accident.

Europe has recently followed the U.S. and Japan in introducing 5.9-GHz frequency band for the communication system, an important step toward a standardized frequency.
