Bridging the Architectural Gap: Integrating Fault-Tolerant Zonal Controllers and Verified Deep Learning Frameworks for Next-Generation Autonomous Vehicular Safety
Hannah Klien , Department of Embedded Systems and Software Engineering, University of Edinburgh, United KingdomAbstract
The rapid transition from traditional internal combustion engines to software-defined autonomous vehicles (AVs) has introduced a dual challenge: the necessity for high-performance computational hardware that remains resilient to physical faults, and the requirement for robust machine learning (ML) models capable of navigating unpredictable real-world environments. This article provides a comprehensive investigation into the integration of fault-tolerant dual-core lockstep architectures, specifically utilizing NXP S32G processors, with advanced deep learning verification and validation (V&V) methodologies. We examine the theoretical underpinnings of memory safety in the POSIX C environment and the Linux kernel, identifying how pointer provenance and privilege minimization through CHERI-based architectures can mitigate security risks at the hardware level. Simultaneously, we explore the challenges of "safely entering the deep," evaluating how simulation-based testing, hierarchical reinforcement learning, and agency-directed test generation provide a structured path toward autonomous vehicle verification. By synthesizing hardware-level fault injection analysis with software-level semantic validation of deep learning algorithms, this research establishes a holistic framework for automotive safety. The study concludes that the future of vehicular autonomy relies on a symbiotic relationship between spatial memory safety, temporal fault tolerance in zonal controllers, and the continuous verification of deep learning models against diverse datasets such as Caltech-101 and the Caltech Pedestrian Dataset.
