Development topics for collaboration
Reality abstraction
Systematic transformation of reality into versatile virtual elements
Strategies for modelling sensors and environments and its calibration/verification proceduresHigh precise maps e.g. including materials for multi-channel perception

Scenario based testing platforms
Complementary use of scenario databases and its models, data and scenarios
Simulation validation: How to validate simulation results
Systematically linking data and scenario marketplaces to targeted ODDs

Innovative data- and service ecosystems
Digital twins will be of increasing relevance in virtual R&D and V&V processes
High degree of automation of processes (e.g. in virtual or simulation-based environments)
Scalability and maintenance of digital twins over the entire product lifetime is essential

Applying the safety caseTransfer and usage of selected safety argumentation building blocks into virtual or physical test facilities
Raise the proportion of virtual or simulation-based methods/tools and the level of evidence
Transferring safety assurance concepts into data and scenario-driven R&D and V&V processesOne example – DLR MiL/SiL simulation toolchain „OSTAR“OSTAR (Open Source Toolchain for Automotive Research)
