TTTech Auto and ZettaScale extend collaboration with the launch of Zetta Auto

2 mins read

TTTech Auto, a specialist in automotive safety software, and ZettaScale Technology, the pioneer in pub/sub/query protocol, have announced the launch of Zetta Auto.

The two companies are delivering a unified communication platform for the automotive industry, initially focusing on making Serviced-Oriented Architecture (SOA) communication safe, performant and predictable.

Extending the scope of the collaboration, Zetta Auto is also paving the way for a much-needed unification across cloud-to-microcontroller communications.

Unlocking the full capabilities of software-defined vehicles requires a communication solution that is interoperable with automotive frameworks and allows software and hardware to evolve independently while being predictable and safe.

Zetta Auto has sought to combine Data Distribution Service (DDS), Time Sensitive Networking (TSN) and Zenoh (pub/sub/query) and, though these unified integration of these protocols, Zetta Auto’s capabilities look to address the specific needs of the automotive industry and deliver adaptable communication solutions for both current and future vehicle architectures.

The cutting-edge 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. Offering interoperability and developer-friendly flexibility the result is a substantial enhancement to end-to-end vehicle performance and robust networking capabilities, which is suited for domain-based and zonal electronic/electrical architectures currently being developed.

Zetta Auto enables manufacturers to use the benefits of TSN, facilitating real-time communication within vehicles. This critical feature plays a pivotal role in 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 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 optimised footprint. It integrates with AUTOSAR Classic, simplifying the development process with its included toolchain, and reducing the need for software component modifications.

“With this launch, we are bringing mature technology already proven in other industries to the automotive industry and combining it with time-sensitive networking capabilities,” said Salvador Rodriguez, Head of Product Management at TTTech Auto.

“In this way, we can unleash the potential of DDS for development teams while keeping system integrability under control. Zetta Auto is our first step in making service-oriented architecture a reality in the automotive industry.”

“We are looking forward to expanding our collaboration with TTTech Auto toward a unified end-to-end solution,” added Angelo Corsaro, PhD, CEO/CTO, ZettaScale. “With Zetta Auto, we are truly harnessing the best-in-class technologies to offer the best in-vehicle platform, along with paving the way to next-generation cloud-to-microcontroller communication and data integration.”

Zetta Auto is compatible with MotionWise, TTTech Auto’s Safety Middleware and enables interoperability with established and standardised software stacks such as Robot Operating System 2 (ROS2) and AUTOSAR, providing 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.

“Together with ZettaScale, we will develop the next industry standard for safety and reliability in the rapidly evolving field of autonomous driving,” said Friedhelm Pickhard, CGO at TTTech Auto. “Zetta Auto is part of a set of software services and tools provided by TTTech Auto to develop vehicle operating systems that meet defined safety and performance standards." 

Zetta Auto is now available for automotive innovation projects.
