Operating model
How V2V works
The approved explanation should connect physical systems, communications, data, security, and operating responsibility.
Vehicle-to-Vehicle communication lets equipped vehicles exchange position, speed, heading, braking, and other time-sensitive data. V2X applications use those broadcasts to detect hazards beyond a driver or onboard sensor's line of sight. V2V depends on interoperable radios, message formats, spectrum, positioning, and credential systems; its benefit therefore depends on compatible deployment across vehicles.

Interoperability
Standards
3GPP TS 22.185
3GPP TS 22.185 defines service requirements for vehicle, pedestrian, infrastructure, and network V2X communication. It matters to V2X because it gives independently developed systems a common technical contract.
ITS-G5
European communications specifications for cooperative intelligent transport systems using short-range vehicle and roadside communications.
IEEE 802.11bd
IEEE 802.11bd defines next-generation 802.11 vehicular radio enhancements designed to coexist with legacy vehicular operation. It matters to V2X because it gives independently developed systems a common technical contract.
802.11p
An amendment to the IEEE 802.11 family designed to support wireless access in vehicular environments and low-latency vehicle communications.
J2735
Defines message sets and data elements used for dedicated short-range and connected-vehicle communications, including safety and mobility messages.
SAE J2945/1
SAE J2945/1 defines minimum performance and behavior for on-board V2V safety communication using SAE J2735 messages. It matters to V2X because it gives independently developed systems a common technical contract.
SAE J3161/1
SAE J3161/1 defines minimum LTE-V2X on-board performance for V2V safety applications. It matters to V2X because it gives independently developed systems a common technical contract.
