As cars gain an increasing amount of partially automated driving functions, the potential to use them in an unsuitable context also increases. To complement the current automotive safety standard ISO 26262, Road vehicles – functional safety, which defines the safety goals regarding hardware malfunction, the standard ISO DPAS 21448 is currently drafted to increase the safety in absence of Electrical/Electronic (E/E) systems malfunctions. This includes that the safety concept should consider the foreseeable misuse by the driver, to increase the safety of (partially) automated driving functions. Abdulkhaleq and Ebel presented a concept based on System-Theoretic Process Analysis (STPA) to derive potential misuse, which we extend by considering additional sources like video sharing sites. A pilot study with three (partially) automated driving functions was conduced and the results used for an evaluation based on the expert feedback. The case study evaluation shows a high acceptance for the need of a misuse analysis in general and the scenarios resulting from the proposed concept.
