To be published on April 2, 2019 by SAE International in United States
As Internet of things for vehicle is getting more and more attention and developing strength, how to release the data power on vehicle safety and usability is a valuable topic to research.Accurate fault isolation and prognostic maintenance is one of the most promising application direction, since it can reduce maintenance time, achieve more asset availability, and promote reliability and safety. In this paper, a comprehensive approach which combined with model-based and knowledge-based method is proposed to addressing the challenges. This paper also presents an application using the comprehensive approach applied in vehicle electric power steering(EPS) system. It can help maintenance person to quickly find out the root cause of the failures in a vehicle. Component and system behaving modes are collected for vehicle manufacture user to access vehicle health status.
