Apply sotif with stpa to step one, deriving inputs as function/operational descriptions and safety acceptance criteria, and outputs as safety requirements or modifications to the function within operational design domain.
Derive the accident model by defining accidents and hazards, link hazards to losses, and establish safety goals and umbrellas, then derive a control structure for autonomous driving.
Apply a state-machine approach to causal factor analysis in SOTIF, linking unsafe control events to hazards, safety goals, and escalation rules to prevent violations.
ISO/PAS 21448 applies to functionality that requires proper situational awareness in order to be safe. The standard is concerned with guaranteeing the safety of the intended functionality — SOTIF — in the absence of a fault.
Automotive engineers out there and safety managers out there are hearing this all day about SOTIF requirements and SOTIF analysis. But are not sure how to achieve compliance to this standard. Now you have the opportunity to do so.
The coarse offers you in-depth awareness and analysis methods to apply SOTIF analysis and derive requirements. it also addresses how this standard is related to ISO26262, how are they different, if one is enough or both of them are required.
