What Is V2V Communication?

Published on

Vehicle-to-vehicle (V2V) communication enables vehicles to wirelessly exchange information about their speed, location, and heading. The technology behind V2V communication allows vehicles to broadcast and receive omni-directional messages (up tp 10 times per speed), creating a 360-degree “awareness” of other vehicles in proximity. Vehicles equipped with appropriate software (or safety applications) can use the messages from surrounding vehicles to determine potential crash threats as they develop. The technology can then employ visual, tactile, and audible alerts-or, a combination of these alerts- to warn drivers. These alerts allow drivers ability to take action to avoid crashes.

These V2V communication messages have a range of more than 300 meters and can detect dangers obscured by traffic, terrain, or weather. V2V communication extends and enhances currently available crash avoidance systems that use radars and cameras to detect collision threats. This new technology doesn’t just help drivers survive a crash—it helps them avoid the crash altogether.

Vehicles that could use V2V communication technology range from cars and trucks to buses and motorcycles. Even bicycles and pedestrians may one day leverage V2V communication technology to enhance their visibility to motorists. Additionally, vehicle information communicated does not identify the driver or vehicle, and technical controls are available to deter vehicle tracking and tampering with the system.

V2V communication technology can increase the performance of vehicle safety systems and help save lives. There were 6.5 million police-reported crashes in 2017, resulting in 37,133 fatalities and 2.7 million injuries. Connected vehicle technologies will provide drivers with the tools they need to an- ticipate potential crashes and significantly reduce the number of lives lost each year.
