Cadillac's V2V communications technology shares vehicles' locations, speeds, directions and traffic conditions up to nearly 1,000 feet away
Cadillac will begin installing vehicle-to-vehicle (V2V) communication systems in the 2017 CTS this month, allowing the vehicles to communicate with each other and their drivers about driving conditions.
The vehicle then communicates with the driver to warn of potential hazards based on the other vehicle’s driving experience. Hazards include hard braking situations, slippery road conditions or disabled vehicles ahead.
Only V2V communication-enabled vehicles can communicate with each other. A Cadillac spokesman said the ultimate goal is for every vehicle to be able to communicate but that “you always need someone to start.”
The V2V systems form an “ad hoc wireless network” which allows the vehicles to share data without the need for good weather, cellular coverage or sightlines, the release said.
"V2V essentially enables the car to sense around corners,” Richard Brekus, the global director of product strategy at Cadillac, said in a statement. “Connecting vehicles through V2V holds tremendous potential, as this technology enables the car to acquire and analyze information outside the bounds of the driver’s field of vision.”
The V2V system uses dedicated short range communications in the 5.9 GHz spectrum band, an automotive channel approved by the Federal Communications Commission.
The system will come standard in the 2017 CTS in U.S. and Canada.
