TTTech Auto, an automotive safety software provider, and ZettaScale Technology, a pioneer in pub/sub/query protocol, launched Zetta Auto. Combining their technology strengths, the companies are delivering a unified communication platform for the automotive industry, initially focusing on making Serviced-Oriented Architecture, or SOA, communication safe, performant and predictable. Extending the scope of the collaboration, Zetta Auto is also paving the way for a unification across the cloud-to-microcontroller communication continuum.  

Unlocking the full capabilities of software-defined vehicles demands a communication solution that's interoperable with automotive frameworks, and allows software and hardware to evolve independently while being performant, predictable and safe. Zetta Auto achieves that by combining the power of Data Distribution Service (DDS), Time Sensitive Networking (TSN) and Zenoh (pub/sub/query). Through the unified integration of the protocols, Zetta Auto’s capabilities are tailored to the needs of the automotive industry, and deliver adaptable communication solutions for current and future vehicle architectures. 

The in-vehicle communication solution, leveraging and extending ZettaScale’s open-core Cyclone DDS, empowers vehicle applications to exchange information across a wide range of operating systems, development languages and complex processor architectures and microcontrollers. Seamless interoperability and developer-friendly flexibility are achieved while ensuring predictable quality of service, remarkable throughput and minimal latency. The result is an enhancement to end-to-end vehicle performance and robust networking capabilities, ideally suited for domain-based and zonal electronic/electrical architectures now being developed. 

Zetta Auto empowers car manufacturers to harness the benefits of TSN, facilitating real-time communication in vehicles. The feature plays a pivotal role in unlocking the era of software-defined vehicles, enabling seamless software integration, validation and verification through end-to-end communication properties. With the inclusion of the TSN tool suite and integration capabilities, car manufacturers can confidently achieve advanced functionality with remarkable speed and efficiency.  

Zetta Auto’s integrated solution for microcontrollers builds on Zenoh Pico, a lightweight implementation of Zenoh, to guarantee minimal CPU and memory usage, resulting in an optimized footprint. It integrates with AUTOSAR Classic, simplifying the development process with its included toolchain, and reducing the need for software component modifications. 

Zetta Auto is compatible with MotionWise, TTTech Auto’s Safety Middleware – on the road in millions of vehicles, and enables interoperability with established and standardized software stacks, such as Robot Operating System 2 (ROS2) and AUTOSAR. That ensures a smooth and efficient integration experience throughout all development phases, empowering automotive developers with a flexible, versatile and robust solution. In addition, Zetta Auto will be extended with ASIL-D certification for in-vehicle communication in early 2024.
