Abstract In this chapter, a process to derive a system-wide functional safety concept for automated road vehicles is presented and a short introduction of Skill and Ability Graphs for a functional safety concept is given. The process to develop a functional safety concept contains an extension to the ISO 26262 standard’s Driver Assistance System development process. This extension is a Skill Graph to model system skills in the concept phase. The Skill Graph improves the Hazard Analysis and Risk Assessment by modeling driving skills early in the development process. Additionally, the Skill Graph is transferred to an Ability Graph, used to design a self-perception and self-representation, which enables monitoring of the system’s operation and functional capabilities online. This self-representation can be part of a technical safety concept. Based on the ability levels, safety actions can be derived which maintain or reach a safe state of operation. As a result, a self-monitoring system is possible, in which humans, either aboard the vehicle or external, do not have to monitor the system.
