In recent years, Prognostic Health Management (PHM) has caught the attention of lots of researchers in a wide range of applications. Thus, many researchers from research institutes, universities and companies have published and patented their findings in various fields of PHM. PHM is a method or technique that can be used to detect performance degradation and forecast remaining life of a system based on the health monitoring information. A number of review papers discussing on PHM methods and techniques have been presented by other researchers but mostly in maintenance of manufacturing equipments, aerospace systems and structural monitoring. This paper focuses on the trend and direction of PHM especially in the automotive industry through published research papers and also patents. The purpose of this paper is to recognize the trend and to provide suggestions for potential future research in PHM for automotive. Accordingly, this paper should offer opportunity for the manufacturers or researchers to get information on current trends and also potential areas that can be further explored in PHM for automotive.
