Reducing the Design Complexity of Automated Vehicle Electrical and Electronic Systems Using a Cyber-physical System Concept

Green transportation dictated by low carbon policies means that vehicle power sources are changing from fossil fuels to electricity. In electric vehicles, the numbers of electronic devices and the complexity of control software are high; design complexity has thus increased. Efforts to reduce the complexity of automated vehicle electrical and electric systems (E/E systems) at the design stage are actively underway. To reduce system design complexity, we introduce a design methodology employing cyber-physical systems (CPS). We designed an automated forklift system to explore the effectiveness of the proposed methodology. This paper shows that the CPS design methodology enables effective development of automated E/E control systems.
