  • Welcome presentation at OSxCAR Consortium Meeting

    OSxCAR Consortium Meeting: Halfway There and on Track

    At the end of April 2026, the partners of the publicly funded OSxCAR project met for a two-day consortium meeting in Wuppertal. The focus was on reviewing the current project status and aligning on the next technical steps.

    At the project midpoint, OSxCAR has made solid progress overall: The system architecture for software-defined vehicle platforms is in place, first WebAssembly-based demonstrators have been implemented, and key components of the SDV testbench — including the reconfigurable switch matrix — are currently being integrated and validated. In parallel, work continues on a hardware-independent test framework and AI-assisted methods for network optimization.

    The meeting was hands-on and work-focused. Alongside brief status updates from all partners, technical details were discussed in depth — particularly around hardware-software integration, test automation, and the preparation of upcoming demonstrations.

    The consortium is confident in its direction and continues to work closely together on delivering the integrated overall system.

  • 2025 Progress Report Finalized

    The 2025 Progress Report summarizes the essential progress and results of the OSxCAR project in 2025. The focus was on cross-platform software, safe validation, and industry-ready demonstrators.

    Highlights:

    • One-binary portability with WebAssembly from PC to MCU successfully demonstrated
    • Shadow mode validation for risk-free real-time testing of new functions
    • Development of a software-defined reconfigurable SDV testbench
    • Real-world demonstrators such as ACMS and anti-pinch window control with positive OEM feedback
    • Progress in standardization, open source, and software-as-a-product

    2025 laid the foundation for scaling, industrialization, and commercialization in 2026.
