In its first reporting period (from September 2022 to February 2024), SUNRISE benchmarked existing international safety assurance frameworks, to be used as the basis for a new CCAM Safety Assurance Framework (SAF) developed under SUNRISE. This SAF should fulfil the needs of all key stakeholders, to the highest possible extend. At the project's midterm (in February 2024), SUNRISE completed a draft version of this SAF, which was finalized in the second reporting period (from March 2024 to August 2025) and presented to target users during the project’s Final Event in June 2025. The final SAF comprises five key parts, covering the pillars of the multi-pillar approach of NATM (ECE/TRANS/WP.29/2021/61 2021): [1] Scenario, [2] Environment, [3] Safety Argument, [4] In-Service Monitoring and Reporting and [5] Audit.
The SUNRISE SAF consists of three main components: a [1] Method, a [2] Toolchain and a [3] Data Framework. Together with the completion of the final SAF, the final versions were finished of these main 3 components. These components are described hereafter, and represent the main results completed during the project.
A METHOD has been established to support the SAF safety argumentation. To lay a solid foundation for this method, a benchmark has been performed on existing standardization efforts and initiatives related to scenario-based safety assessment. The creation of this method also included the definition of terms related to scenarios, methods for scenario selection, sub-space creation and dynamic allocation to test instances (including virtual, hybrid and physical test environments), and a variety of metrics and rating procedures.
A TOOLCHAIN has been defined, taking the shape of a harmonised V&V simulation framework that focuses on modularity, scalability and interoperability and recommends the use of standardised data formats and open interfaces. This framework can be used to select a set of tools for safety assessment of CCAM systems, including approaches for virtual, hybrid and physical testing. Its modular structure allows for easy exchange of individual subsystems. The main subsystems include [1] a test case manager, [2] an environment simulator, [5] a subject vehicle simulator, [3] a traffic agents simulator, [4] a connectivity simulator and [6] simulation model validation.
A DATA FRAMEWORK has been designed, enabling online access, connection and harmonization of external Scenario Databases (SCDBs). This framework is devised to allow its users to perform mainly: [1] query-based extraction of all safety relevant scenarios from a wide variety of connected external databases, and [2] allocation of selected scenarios to a variety of test environments.
