Vehicle to Vehicle – V2V

Vehicle to Vehicle communication conveys information between sensor-equipped vehicles about speed, traffic conditions, road quality or other safety-critical data.

As an evolving suite of ideas, most V2V communication is restricted to vehicles from the same manufacturer or using the same software systems while industry standards develop.

In some cases, a vehicle may access data from other vehicles via a secondary platform, such as a local wireless network, or mobile communications infrastructure.

When data is exchanged between vehicles and infrastructure, this becomes V2I, or exchanged with other devices generally, then V2X (where X is deliberately ambiguous)
