Abstract
Developing safe vehicle automation systems is crucial for the commercialization of automated driving. One of the major challenges for the release of fully automated driving is functional safety. Automated driving systems explode in complexity due to an infinite number of occurring scenarios. Elaborated safety goals from a hazard analysis and risk assessment (HARA) are broad and more challenging to break down into safety requirements. This work presents a structure for a fault tree-based approach to derive safety requirements from safety goals systematically according to the international standard of functional safety for road vehicles known as ISO 26262. The methodology is applied on the example of automated valet parking (AVP). The approach simplifies the breakdown of complex safety goals and provides a more complete set of safety requirements.
