Prognostics and Engine Health Management of Vehicle using Automotive Sensor Systems

Currently, automotive electronics and sensor systems are partially integrated. Therefore, these are major issues in providing comfort, safety and communication. Prognostics and Health Management (PHM) includes certain technologies and methods that would access the reliability of the product in its actual life cycle conditions, in order to determine the reasons of failure and mitigates system risk. Today, the development of diagnostic are prognostics techniques, which use accurate degradation procedures by appropriate sensor selection, fusion, still remains a vital& issue of prime important. Also, an unified monitoring& prognostics approach that prevents failure by analyzing degradation features is suggested as a general framework to overcome the unsolved issues and challenges. Thus, PHM is an enabling discipline consisting of technologies and methods to assess the reliability of a product in its actual life cycle conditions to determine the advent of failure and mitigate system risk. Sensor system is needed for PHM to monitor environmental, operational and performance-related characteristics. The gathered data can be analyzed to assess product health and predict remaining life.
