Meaning and timing
Messages preserve semantics, units, coordinate frames, validity and application-specific timing.
IAF Standards Programme
IAF Connected Vehicle & Ecosystem
Interoperability, reliability and security across vehicles, infrastructure and services
A common method for assessing whether connected information arrives in time, retains its meaning, comes from an authorized source and can be used without unacceptable risk.

At a glance
Connectivity Assurance Covers the Complete Ecosystem
The framework evaluates vehicles, components, roadside assets, services and deployments together with the dependencies that can invalidate a claimed outcome, including what happens when networks, positioning or trust services fail.
Trusted participation
Identity, credentials, authority, revocation, misuse resistance and privacy are assessed together.
Safe degradation
Functions expose unavailable or uncertain states and retain tested fallback and recovery behaviour.
Operational evidence
Geography, traffic, radio conditions, counterpart implementations and supported versions bound each result.
Assessment architecture
Five Object Codes Describe the Assessment Boundary
Object codes are scope descriptions, not quality grades. More than one may be selected for an ecosystem evaluation.
Complete vehicle integration
Variant, onboard hardware and software, enabled services and external dependencies.
Device or retrofit scope
Hardware, firmware, host assumptions, installation limits and integration tests.
Roadside or site assets
Geometry, controller interfaces, radio paths, power, backhaul and operating ownership.
Connected service release
Region, interfaces, providers, production version and continuing responsibility.
Combined deployment
An identified combination of vehicles, infrastructure and services with operational agreements.
Framework structure
The Main Clauses in Six Clear Groups
This table provides a concise route through the working draft. The complete technical requirements and annexes remain available in the PDF.
| Clauses | Group | What it covers |
|---|---|---|
| 01-04 | Scope and Profiles | Assessment objects, application rules, terminology, enabled functions and operating domains. |
| 05-13 | Governance and Digital Trust | Deployment duties, risk, architecture, radio, meaning, timing, identity, cybersecurity and privacy. |
| 14-20 | Connected Mobility Services | V2V, smart cities, vulnerable road users, emergencies, cloud, cooperative functions and human interaction. |
| 21-24 | Lifecycle and Resilience | Software, supply chain, service continuity, performance, reliability, physical environment and resources. |
| 25-28 | Verification and Decisions | Validation programmes, evidence, uncertainty, decision rules, public claims and assurance records. |
| 29-30 | Operations and Extension | Incidents, corrective action, future capabilities and controlled technical extension. |

Key ideas
What Readers Should Take Away
Externally operated services remain inside the boundary
A dependency is included whenever its failure or misuse can invalidate the claimed outcome.
Identical service names do not prove compatibility
Interfaces need complete profiles, executable test vectors and independent counterpart testing.
A city demonstration is not every-city compatibility
Geography, roads, traffic, weather, radio, positioning and infrastructure maturity remain explicit.
Loss of connection must have an understandable state
Degraded behaviour, fallback, recovery and responsible parties are defined before operation.
A component result cannot become whole-vehicle assurance
Public wording identifies the exact object, functions, versions and unverified conditions.
Using the document
From a Frozen Deployment Profile to a Bounded Connectivity Decision
Development status: Revised Technical Text 0.2 remains a development proposal. Deployment profiles, numerical calibration, pilots and formal adoption are still required.
01Declare objects, functions, geography, versions and counterpart roles
02Complete the profile, service contracts and dependency map
03Test valid, invalid, stale, contradictory and failure scenarios
04Publish evidence, uncertainty, limitations and reassessment triggers
