As autonomous vehicles demand higher performance and safety, traditional E/E architectures are giving way to zonal designs. This presentation explores how TSN and fail-silent domain controllers can be architected to meet ASIL-D requirements for timing, fault isolation, and availability. It presents a reference architecture leveraging TSN standards (e.g., 802.1Qbv, Qci) and lock-step computing with safety monitors to ensure deterministic behavior and resilience. Key trade-offs and implementation strategies are discussed, with insights from hardware-in-the-loop testing and alignment with ISO 26262 and ISO/TS 5083.
In this session, you will gain insights into:
- Prioritizing safety-critical traffic while maintaining bandwidth efficiency
- Using lock-step cores and watchdogs to ensure fast, safe failure handling
- Linking safety goals to network and compute design with standards-based validation
