Vehicle-to-vehicle (V2V) is an automobile technology designed to allow automobiles to "talk" to each other. Using a region of the 5.9 GHz band, V2V systems allow vehicles to communicate with each other and with roadside stations.
Using a region of the 5.9 GHz band, V2V systems allow vehicles to communicate with each other and with roadside stations. Networks of vehicles can help avoid congestion, find better routes, and aid law enforcement. V2V is currently in active development by General Motors, which demonstrated the system in 2006 using Cadillac vehicles. Other automakers working on V2V include Toyota, BMW, Daimler, Honda, Audi, Volvo and the Car-to-Car communication consortium.
