Time-Sensitive Networking (TSN) has emerged as a core technology within Software-Defined Vehicle (SDV) architectures. TSN’s ability to provide reliable communication, particularly when transmitting both best-effort and critical data over the same Ethernet backbone, is reshaping the automotive landscape. At TTTech Auto, deterministic communication over Ethernet lies at the core of our identity, and our new Zetta Auto Experience Kit embodies this commitment by showcasing the synergy of DDS and TSN.
Exploring the Integration of DDS and TSN
Diving into the Zetta Auto Experience Kit, users can now firsthand experience the powerful combination of DDS and TSN. This kit, built on the Zetta Auto solution, comes Time Aware Shaper-enabled (Qbv) and includes integrated network planning. The network description, including timing constraints, is used as an input to our tooling to produce a switch-agnostic TSN configuration.
Key benefits of the Zetta Auto Experience Kit
- Accelerated Evaluation: The Zetta Auto solution is pre-integrated on automotive hardware, accelerating evaluation projects.
- Reference applications within the kit illustrate the capabilities of DDS, Zenoh, and TSN.
- Expert Support: Users benefit from dedicated assistance from our company's experts.
- Comprehensive Licensing: All necessary licenses are provided for the evaluation period.
Demonstrating Reliability: The Moose Test Showcases DDS/TSN Combo Benefits
In a pivotal demonstration, the Moose Test underscores the importance of integrating TSN for a deterministic network that ensures system stability, especially in critical scenarios. Through an engaging simulation based on synthetic data, viewers are able to witness the impact of TSN on vehicle maneuverability during obstacle evasion.
In the test, modules for Object Detection and Vehicle Control, integrated as DDS applications, communicate over Ethernet. Additional best-effort data is induced to overload the network, simulating real-world conditions. When TSN is switched off, the vehicle fails to execute the evasive maneuver due to critical data not being prioritized across the network. However, with TSN activated, the vehicle successfully avoids the obstacle, demonstrating the pivotal role of TSN in ensuring the safety and efficiency of the system.
