Abstract:
Safety and security are two inter-dependent key properties of autonomous vehicles. They are aimed at protecting the vehicles from accidental failures and intentional attacks, which could lead to injuries and loss of lives. The selection of safety and security countermeasures for autonomous vehicles depends on the driving automation levels, defined by the international standard SAE J3016. However, current vehicle safety standards ISO 26262 do not take the driving automation levels into consideration. We propose an approach for integrating autonomous vehicle safety and security processes, which is compliant with the international standards SAE J3016, SAE J3061, and ISO 26262, and which considers driving automation levels. It uses the Six-Step Model as a backbone for achieving integration and alignment among safety and security processes and artefacts. The Six-Step Model incorporates six hierarchies of autonomous vehicles, namely, functions, structure, failures, attack, safety countermeasures, and security countermeasures. It ensures the consistency among these hierarchies throughout the entire autonomous vehicle’s life-cycle.
