Simulation-based Safety Assurance for an AVP System incorporating Learning-Enabled Components

Abstract

There have been major developments in Automated Driving (AD) and Driving Assist Systems (ADAS) in recent years. However, their safety assurance, thus methodologies for testing, verification and validation AD/ADAS safety-critical applications remain as one the main challenges. Inevitably AI also penetrates into AD/ADAS applications, such as object detection. Despite important benefits, adoption of such learned-enabled components and systems in safety-critical scenarios causes that conventional testing approaches (e.g., distance-based testing in automotive) quickly become infeasible. Similarly, safety engineering approaches usually assume model-based components and do not handle learning-enabled ones well. The authors have participated in the public-funded project FOCETA , and developed an Automated Valet Parking (AVP) use case. As the nature of the baseline implementation is imperfect, it offers a space for continuous improvement based on modelling, verification, validation, and monitoring techniques. In this publication, we explain the simulation-based development platform that is designed to verify and validate safety-critical learning-enabled systems in continuous engineering loops.
