Wind River have collaborated with TTTech, and announced that it 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.

Building on their long-standing partnership, Wind River and TTTech Auto, a leading provider of safe software and hardware platforms for automated driving, have worked together to develop highly scalable engine control units 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. This is in vehicles including the 2018 Audi A8 – one of the auto industry’s most advanced connected vehicles on the market. 

TTTech Auto operates under the umbrella of TTTech Group. These globally-oriented high-tech companies offer real-time networking platforms and safety controls for a variety of industries, such as automotive, aerospace, off-highway, energy production, railway, and industrial automation. TTTech Group builds on 20 years of technology leadership with extensive experience in collaborating with market leaders.

“In the imminently-approaching autonomous future, automakers must keep up with a rapid pace of innovation,” said Marques McCammon, vice president of Automotive at Wind River.

“However, the stakes are incredibly high. By working with leaders like TTTech, Wind River is helping carmakers accelerate their development cycles to deliver innovative products, while also maintaining the highest levels of safety.

“When passenger safety is on the line, it will be essential to turn to leaders with proven technologies and expertise in mission-critical applications.”

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.

To quote Georg Niedrist, senior vice president of Safety Products and Integration at TTTech Auto: “With the rise of connectivity and autonomous driving, the automotive environment is becoming more complex and creates new challenges.

“Together with a software expert like Wind River, TTTech can deliver advanced automotive platforms to help OEMs meet their demanding requirements, schedules, and, ultimately, their objectives."

A high-performance RTOS, VxWorks is tuned for both determinism and responsiveness. Its technology includes a modular, future-proof architecture that separates the operating system's kernel from applications and other packages, allowing for fixes and feature updates with minimal rework, testing, or re-certification.

The enhanced multi-core 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 (ASIL).
