NHTSA is Developing Vehicle Communications
The National Highway Traffic Safety Administration (NHTSA) is helping the automotive industry develop a new technology to help make cars safer. The technology is termed vehicle to vehicle (V2V) communications and it is being developed to provide vehicles with close-range communication abilities. Vehicle sensors have been focused on helping drivers determine where their vehicle is in relation to the surrounding environment. Rear backup cameras, vehicle sonar, lane departure warnings, and active emergency braking are all systems that assist the driver in knowing where their vehicle is in relation to other object. V2V communications is intended to enhance the abilities of current safety sensors by sending and receiving vehicle information between vehicles as they travel down the roadway. How does it work? Wireless transmitters and receivers located in each vehicle work to communicate vehicle information between the onboard vehicle and surrounding vehicles. The wireless transmitters can transmit data on vehicle speed and heading, and can also sense position of the vehicle in relation to other vehicles with the same sensor setups. The wireless signals are designed to detect and analyze vehicle information from other vehicles that are located nearby, to a proximity distance of about 300 meters. For example, a vehicle following another vehicle on the same roadway would detect information about the front vehicle’s speed or whether or not the front vehicle had begun emergency braking, providing the driver of the following vehicle with either a brake assist, or a noticeable warning as to the behavior of the front vehicle.
The National Highway Traffic Safety Administration is expecting that the V2V systems will help increase vehicle safety and reduce the number of automobile crashes, however other uses for the system could be implemented as well. For example, detection of stolen vehicles could be sensed by vehicles surrounding the stolen vehicle. Information pertaining to the vehicle’s driver could also be shared between other vehicles. V2V communication will allow more vehicle and driver data to be collected which could benefit the entire transportation industry as a whole.
