Automotive Grade Linux (AGL) is an open-source automotive software platform, not a blanket functional-safety certification. AGL documentation covers vehicle-software areas that include functional safety, but that scope does not establish that AGL, a particular AGL release, or a vehicle feature built with it is certified or compliant with ISO 26262. The responsible vehicle program must assess its actual function, system boundary, configuration, and safety evidence.
What functional safety in AGL means
AGL is a collaborative project whose Unified Code Base (UCB) is described as a Linux distribution for in-vehicle infotainment and connected-car experiences. AGL documentation also identifies instrument clusters, head-up displays (HUDs), telematics, advanced driver-assistance systems (ADAS), functional safety, and autonomous driving among the areas it addresses.
That broad scope describes the project’s automotive software work; it is not a safety rating for every component or deployment. The AGL Requirements Specification says, “The scope of the AGL Requirements Spec is to define the architecture of the Automotive Grade Linux software platform.” It generally defines platform architecture and core software rather than requirements for each product-specific application.
In practical terms, an automaker or system integrator may use AGL components as part of a safety-relevant vehicle system, but must determine what the selected components do in that system and substantiate the safety case for the deployed product. The word “AGL” alone does not answer whether a particular function is safe or compliant.

What ISO 26262-6:2018 covers
ISO 26262-6:2018, Road vehicles — Functional safety — Part 6: Product development at the software level, addresses software-level development for automotive applications. ISO identifies it as Edition 2, published in December 2018 and reviewed and confirmed in 2024, so the catalog lists it as current.
The ISO abstract says, “This document specifies the requirements for product development at the software level for automotive applications, including the following:” Its listed areas include:

- Official Record Book: This hardcover log book is designed to record the purchase, sale, or exchange of new and used motor vehicles.
- Comprehensive Tracking: With 975 vehicle record entries, it allows for meticulous documentation of automotive transactions.
- Durable Construction: The sturdy hardcover binding ensures long-lasting use and protection of important records.
- Convenient Size: Measuring 11.5 x 9.5 inches, this book offers ample space for detailed vehicle information.
- Essential Tool: An indispensable resource for car dealers, ensuring proper documentation and compliance with regulations.
- Software safety requirements and software architectural design
- Software unit design and implementation
- Software unit verification
- Software integration and verification
- Embedded software testing
Part 6 is relevant to software development, but it is not the entire ISO 26262 series and does not, by itself, certify a platform, vehicle, or organization. ISO describes the standard as a framework for integrating functional-safety activities into a company-specific development framework, with technical and process requirements. Whether a product conforms cannot be inferred just from its use of AGL or from a reference to Part 6.
Where AGL ends and the vehicle program’s work begins
The key distinction is between a shared platform and the complete system that performs a vehicle function. AGL’s architecture documentation describes layers that include the App/HMI, Application Framework, Services, and Operating System. Its Requirements Specification generally leaves application requirements to the product project, with a noted home-screen exception.

It then needs evidence appropriate to the function and development process. A platform specification can help define what software is being integrated; it does not replace product-specific requirements, verification, integration, testing, or the wider safety work needed for a conformity assessment.
This is a conclusion from the different scopes of AGL’s platform specification and ISO 26262-6, not an assessment of any particular AGL product or vehicle program.

How to assess an AGL-based safety-relevant system
Do not assign a single “safety level” to AGL. Assess the intended function and the precise deployment. These questions help make that boundary concrete:
- Define the function and hazard context. Identify what the vehicle feature is intended to do and the safety goals established by the responsible program. The relevant safety assessment depends on that context, not on the platform name alone.
- Inventory the software boundary. Record which AGL components and release are used, which applications are product-specific, and what additional software is integrated. The AGL Requirements Specification covers platform architecture and core software; application requirements are generally handled by product projects.
- Document the architecture and isolation. Identify the hardware, partitions, communication paths, and any virtualization arrangement. Establish how the actual deployment handles interactions between functions; an architecture diagram by itself does not establish safety qualification.
- Connect software work to evidence. For the applicable development scope, track requirements through architecture, implementation, verification, integration, and testing. ISO 26262-6 names these software-level activity areas, while the complete compliance question depends on the applicable safety lifecycle and system context.
- Check configuration-specific supplier evidence. Tie any evidence to the exact release, board, toolchain, components, and configuration being deployed. A generic platform description or evidence for a different configuration does not automatically establish the status of the product under review.
- Make a bounded conclusion. State what was assessed, against which applicable requirements and configuration, and what the evidence supports. Do not turn platform adoption into a claim of ISO compliance or certification without a substantiated assessment.
What AGL virtualization material can—and cannot—show
A 2018 AGL Virtualization Expert Group document depicts AGL infotainment, instrument-cluster, HUD, and telematics functions alongside third-party automotive functions over a virtualization platform and hardware. It discusses automotive regulations and ISO 26262 in that architectural context.

Qualification depends on the actual components and configuration as well as the evidence for the intended system.
What can be concluded about AGL’s certification status
The AGL and ISO materials described here establish platform scope and the scope of a software-development standard; they do not establish a current, release-specific AGL safety manual, certificate, or ASIL claim. That limitation should be read narrowly: it does not establish that no such work or documentation exists. Anyone making a conformity claim needs to verify the relevant materials for the exact release and deployment, then assess them within the vehicle program’s applicable safety process.
