ISO 4272:2022 PDF

Overview

ISO 4272:2022 - Intelligent transport systems - Truck platooning systems (TPS) defines the functional and operational requirements for truck platooning control. It standardizes terminology, operation state diagrams, and the two core platooning control functions: the Platooning Operation Control Function (POCF) and the Platooning Manoeuvre Control Function (PMCF). The standard covers heavy goods vehicles with on‑board drivers operating at driving automation levels 1 and 2, and addresses vehicle-to-vehicle (V2V) and optional vehicle-to-infrastructure (V2I) data needed to form and manage platoons. Back office (BO) functions are explicitly out of scope.

Key topics and technical requirements

• Terms, definitions and operation states for consistent TPS language and state transitions.
• POCF: rules and procedures governing how vehicles join and leave a platoon; operation sequencing and requirements for membership changes.
• PMCF: guidance for coordinated longitudinal and lateral control (e.g., cooperative adaptive cruise control concepts), including cruising, join/leave manoeuvres, cut-in/cut-out and lane changes.
• Communication data: V2V and optional V2I message elements required to support POCF and PMCF, including local roadside and broader network/cloud exchanges.
• Platoon formation strategies: ad-hoc vs planned formation, and system types such as top‑down managed (BO/LV-managed) and peer‑to‑peer platooning.
• Functional evaluation test methods: standardized tests and conditions for validating join, leave, cruising, cut-in and cut-out behaviours.
• Scope limits: applies to multi‑brand heavy vehicles with drivers; excludes light trucks, buses, passenger cars and back office operations.

Practical applications and users

Who benefits from ISO 4272:2022:

• Vehicle OEMs and Tier suppliers designing control systems (POCF/PMCF) and V2V/V2I interfaces.
• Fleet operators and logistics companies planning platoon-compatible vehicle procurement and operations.
• ITS integrators and software developers implementing platooning algorithms and communication stacks.
• Test laboratories and certification bodies performing the functional evaluation tests described in the standard.
• Road authorities and regulators assessing operational and safety requirements for platooning deployments.

Practical uses:

• Standardizing platoon join/leave behavior across brands to enable interoperable multi‑fleet platoons.
• Defining required message sets and test procedures to support safe roll-out of truck platooning on motorways.
• Informing procurement specifications and regulatory frameworks for platooning trials.
