Wind River has provided its VxWorks real-time operating system to power the latest versions of MotionWise, TTTech Auto’s safety-software platform for autonomous driving applications. Wind River and TTTech Auto have worked together to develop highly scalable ECUs based on networked multi-core system-on-chips for advanced safety-critical automotive applications. As an underlying software platform for the Audi zFAS architecture, VxWorks maintains and monitors the safety of critical applications. The zFAS platform enables automated driving assistance features such as lane assist, adaptive cruise control, and intersection assist in vehicles including the 2018 Audi A8.
VxWorks is designed to host several safety-related software components side by side with non–safety-related components in the overall automotive system architecture. TTTech Auto’s platform was designed for ADAS functions, including autonomous driving and other automotive video camera–based vision applications. The platform can be connected to multiple cameras, and it features deterministic Ethernet networking capabilities.
A high-performance RTOS, VxWorks is tuned for both determinism and responsiveness. Its technology includes a modular, future-proof architecture that separates the OS kernel from applications and other packages, allowing for fixes and feature updates with minimal rework, testing, or recertification. The enhanced multicore safety scheduler enables time, resource, and space partitioning for different criticality applications to run side by side and still meet safety standards. VxWorks is a trusted platform with a proven track record in safety- and security-certified environments, making it ideal for current and future applications for connected and autonomous vehicles.
In addition to VxWorks software, Wind River provided TTTech Auto with board support packages, middleware development, and network stack integration. The work also included preparation of artifacts and work products for the sensor system host in accordance with functional safety standard ISO 26262, Automotive Safety Integrity Level.
