V2V1

V2V1 is a term encountered in discussions of vehicle communications and software versioning. In a hypothetical or speculative context, V2V1 stands for Vehicle-to-Vehicle Interface Version 1, a first iteration of a protocol intended to support the exchange of basic data between moving vehicles. The designation is used inconsistently across sources and may refer to different proposals rather than a single formal standard.

In practical discussions, V2V1 is often described as an early step toward automated safety messaging, enabling vehicles to share short status data such as position, speed, heading, and intended maneuvers. Messages would be transmitted over short-range wireless links and would be designed for low latency, high reliability, and privacy-conscious operation. Security considerations would include mutual authentication, message integrity, replay protection, and access controls. Architecturally, V2V1 is envisioned as a layered stack with a physical or link layer for wireless transmission and an application layer for data encoding, with provisions to coexist with other vehicular networks and spectrum usage.

V2V1 is frequently discussed alongside real-world standards such as DSRC (IEEE 802.11p) and C-V2X, where the term may appear as a historical label or a conceptual placeholder rather than an actual deployed specification. The status and adoption of V2V1 remain unclear, and references are typically found in academic work, speculative designs, or roadmaps rather than official standards catalogs.
