What type of communications occur on cars

Vehicle-to-everything V2X technology could potentially cha nge that within the next several years. Utilizing wireless signals from nearby connected devices, including other cars as well as sensors on infrastructure and even smartphones, V 2X systems allow cars to see beyond their line of vision, enabling them to more quickly and accurately identify, detect, and predict the actions of oncoming vehicles.

This provides an added layer of safety, a critical feature for driver assistance and fully autonomous driving technology. In addition to safety, V2X communication has the potential to drive efficiencies across the entire transportation ecosystem. Better vehicle communication and navigation could help re-route drivers around detours and traffic jams, and even help decrease traffic overall, which would ultimately lower fuel consumption.

Five to 10 hops on the network would gather traffic conditions a mile ahead. On the first cars, V2V warnings might come to the driver as an alert, perhaps a red light that flashes in the instrument panel, or an amber then red alert for escalating problems. It might indicate the direction of the threat.

All that is fluid for now since V2V is still a concept with several thousand working prototypes or retrofitted test cars. Most of the prototypes have advanced to stage where the cars brake and sometimes steer around hazards. Traffic signals or other stationary devices are called V2I, or vehicle to infrastructure.
