The SUNRISE project develops and demonstrates a harmonised Safety Assurance Framework (SAF) for Connected, Cooperative and Automated Mobility (CCAM) systems. The framework has been created in close alignment with the UNECE New Assessment/Test Method (NATM), and past and on-going international projects and initiatives. It also aligns with standardisation efforts in various standardisation bodies such as ISO, ASAM, SAE, and BSI. At the core of the SAF lies the Performance Assurance flow, which structures how safety evidence is generated and assessed. This flow is organised into three interconnected blocks: Scenario, Environment, and Safety Argument. The Scenario block encompasses the creation, formatting, and storage of scenarios that can be retrived to cover the system’s Operational Design Domain (ODD) and behaviour. The Environment block addresses the concretisation of test cases, their allocation across virtual, proving-ground, and real-world environments, and their execution. The Safety Argument block covers evaluation of results, coverage analysis, and integration into a safety case that supports decisions on system readiness. Together, these steps provide a traceable, repeatable process for assessing whether automated driving functions meet defined safety targets. To complete the SAF, it also includes an Input layer, where ODDs and behaviour of the system is incorporated to instantiate tests, and an Audit pillar, which assesses the robustness of the manufacturer’s safety management system and applied processes. An In-Service Monitoring and Reporting (ISMR) pillar ensures continuity during deployment by enabling feedback of operational data and identification of new scenarios. The SUNRISE SAF has been developed as an industry-wide effort, providing a harmonised, evidence-based, and future-proofing framework for the safe deployment of CCAM systems.
