Functional Safety of Automated Driving Systems: Does ISO 26262 Meet the Challenges?

AbstractStructuring the early design phase of automotive systems is an important part of efficient and successful development processes. Today, safety considerations (e.g., the safety life cycle of ISO 26262) significantly affect the course of development. Preliminary designs are expressed in functional system architectures, which are required to form safety concepts. Thus, mapping tasks and work products to a reference process during early design stages is an important part of structuring the system development. This contribution describes the systematic creation and notation of the functional safety concept within the concept phase of development of an unmanned protective vehicle within the research project aFAS. Different stages of preliminary design and dependencies between them are displayed by the work products created and used. The full set of functional safety requirements and an excerpt of the safety argument structure of the SAE level 4 application are presented.

With the improvement and development in the automotive, the safety related aspects are also becoming more important. Hence there is a stringent demand for the Functional Safety and reliability. In these years, most of the vehicles are made with electrical and electronic components and systems which include lots of Electronic Controller Units (ECUs), electronic sensors, bus systems with coding. Due to the complexity in application of these electrical, electronics and programmable electronics, it is necessary to analyze the potential risk of malfunction for automotive systems. Thus, ISO 26262 has been introduced for automotive electrical/electronic (E/E) systems which ensure the complete safety installation of all ECUs, E/E systems its technical as well as management issues. In this paper, functional safety in accordance with ISO 26262 Part 3 of an electric traction inverter is done, the Functional safety report is generated in MEDINI TOOL and the short circuit fault of traction inverter is considered for Functional safety using MATLAB/SIMULINK.
