Wind River teams with TTTech for autonomous driving and advanced automotive applications

5 June 2014

Wind River is working with TTTech to develop safety-related electronic control units (ECUs) based on networked multi-core system-on-chips (SoCs) for advanced automotive applications, such as autonomous driving. Wind River contributes as a key software partner and provides its VxWorks real-time operating system (RTOS)—conforming to the ISO 26262 safety standard—for the new ECU platform.

TTTech selected VxWorks to host several safety-related software components side by side with non-safety related components in the overall system architecture.

The ECU is designed for use in advanced driver assistance systems (ADAS), including autonomous driving and other automotive video camera–based vision applications. The ECU can be connected to multiple cameras and features deterministic Ethernet networking capabilities, including TTTech’s TTEthernet switch technology supporting 100 Mbit/s as well as 1 Gbit/s.

TTTech is a supplier of networking solutions based on time-triggered technology and modular safety platforms, and its technologies are used in various industries such as automotive, aerospace, off-highway, energy production, railway and industrial process automation. For example, TTTech has worked on the new ADAS platform for Audi for innovative functions such as piloted driving and parking.

The role of software is growing as automotive systems get more sophisticated and as the Internet of Things demands new levels of connectivity and intelligence. Automotive companies must add innovation while maintaining the necessary levels of safety. The issue of safety is especially paramount as capabilities such as autonomous driving become a reality.

—Georg Doll, vice president and general manager of worldwide automotive solutions at Wind River

VxWorks is a high-performance RTOS tuned for both determinism and responsiveness. The latest VxWorks includes a modular architecture that separates the OS kernel from applications and other packages, allowing for bug fixes and new feature updates with minimal rework, testing, or recertification. Additionally, 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 record in safety- and security-certified environments.

Additionally, certain modules of the TTTech ECU platform require Automotive Safety Integrity Level (ASIL) certification of the ISO 26262 Functional Safety for Road Vehicles standard. Meeting the various ASIL levels of safety measures requires exceptional rigor in development. Drawing from decades of embedded software and automotive experience, Wind River can provide customers with expertise across a variety of areas, not only in in-vehicle infotainment (IVI) but also safety, security, and real-time telematics.

Beyond VxWorks and specialized services, the Wind River automotive portfolio also includes Wind River Platform for Infotainment to address multimedia and connectivity; technologies such as iOS connectivity, fastboot, Audio Video Bridging (AVB) Android, GENIVI expertise and solutions, Tizen integration services, Security Profile for Wind River Linux and tools such as Wind River Diab Compiler, Wind River Simics simulation, and virtualization technologies.
