Outline
To address safety challenges arising from dynamic variations in operational capability boundaries, shifts in driving responsibility, and the activation of risk mitigation strategies in automated driving systems under multiple operational modes, this paper proposes a safety argumentation method for operational mode transitions. The method constructs a three-layer finite state machine model of"operational mode-operational state-behavioral response"to formally describe multi-mode operation and transition logic. Furthermore, a three-dimensional verification model of"state machine path, scenario type, safety evidence chain" is proposed to systematically link regulatory safety requirements with engineering design, testing and validation activities, and safety evidence. Typical scenarios are used to demonstrate the complete process from safety requirement decomposition and model construction to validation implementation and safety argumentation, providing an engineering reference for the safety design, regulatory review, and compliance decision-making of multi-mode automated driving systems.
