The increasing complexity of autonomous off-highway vehicles, particularly in mining, demands robust safety assurance for Electronic/Electrical (E/E) systems. This paper presents an integrated framework combining Functional Safety (FuSa) and Safety of the Intended Functionality (SOTIF) to address risks in autonomous haulage systems.FuSa, based on ISO 190141 and IEC 615082, mitigates hazards from system failures, while SOTIF, adapted from ISO 214483 addresses functional insufficiency and misuse in complex operational environments. We propose a comprehensive verification and validation (VV) strategy that identifies hazardous scenarios, quantifies risks, and ensures acceptable safety levels.By tailoring automotive SOTIF standards to off-highway applications, this approach enhances safety for autonomous vehicles in unstructured, high-risk settings, providing a foundation for future industry standards.
