摘要
This paper presents a methodology called Rigorous Analysis Template Process (RATP) for analysing the behaviours and interactions of multiple components in a Self-Driving Vehicle (SDV) to ensure its system safety, especially when a human driver is involved as a fallback option for handling hazardous events. RATP uses Systems-Theoretic Processes Analysis (STPA) and Event-B formal method to gradually identify safety requirements and build their rigours models. The output of RATP is a set of safety requirements that guide the development of a rigorous model to maintain the system safety against identified hazardous states at different levels of abstraction. The main advantage of RATP is to allow the behaviours of a system to be analysed from a high-abstraction layer to a more detailed concrete layer.
