Abstract

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.
