A demonstration of embedded health management technology for the HEMTT LHS vehicle

This paper describes the development and implementation of a prototype embedded health management system for the U.S. Army HEMTT M1120A2+ vehicle. Diagnostic, advanced diagnostic and prognostic technologies were developed and implemented for four of the vehicles subsystems including the engine, transmission, load handling system and main vehicle batteries. A centralized vehicle health information analyzer and server was developed and resides in a hardened on-board computer. All of the sensors and devices are networked into this computer, which stores and processes the data for display to the graphical user interface. This interface was developed to provide vehicle operational status data and sub-system health information in an actionable format that is simple to understand and intuitive to operators and maintainers. The HEMTT M1120A2+ vehicle served as a platform for showing how the health management technology can be integrated into a vehicle to provide diagnostic and prognostic information to operator and maintainers. It also helps to create the 'vision' for the implementation of health management technology for legacy and future ground vehicles
