Operating model
How CACC works
The approved explanation should connect physical systems, communications, data, security, and operating responsibility.
Cooperative Adaptive Cruise Control uses V2V messages about acceleration, braking, speed, or intent alongside onboard sensing to coordinate following behavior. Communication can improve responsiveness and enable shorter stable gaps, but safe operation still depends on local sensors, control design, communication quality, and a defined fallback when data is unavailable.

SAE J3216
SAE J3216 defines a vocabulary and classes for cooperative driving automation that distinguish coordination among road users and infrastructure. It matters to V2X because it gives independently developed systems a common technical contract.
