Vehicle embedded health monitoring and diagnostic system

This paper will cover the background, current spiral developments, roll out, and sustainment of the US Army's newest At-Platform Automatic Test Systems (APATS) equipment for TWVs (Tactical Wheeled Vehicles). The equipment, called the SWICE (Smart Wireless Internal Combustion Engine) system, was developed for vehicle diagnostics systems in at-platform and embedded applications, including prognostics. Based on the WICE (Wireless Internal Combustion Engine) kit, consisting of hardware devices, software applications and other interface components, the Army's Product Director-Test, Measurement & Diagnostic Equipment (PD-TMDE) supported SWICE kit provides a low cost Embedded Computer System supporting CBM (Condition Based Maintenance) system deployment. An overview of the SWICE system operation is described, including the Smart Wireless Diagnostic Sensor (SWDS) device, features of the Vehicle Integrated Diagnostics Software-Field (VIDS-F) implementation, and the vehicle Diagnostics Software (DS) application. Also covered will be the functions of the Prognostics Client "plug-in" module and integrated support for the Common Logistic Operating Environment (CLOE) implementation. Finally, the potential for coordinating new industry standards for developing common prognostic functions via IEEE, SAE, ISO, and other allied standards organizations will be presented, along with the concept of leveraging the SWICE/SWDS as a "MiniVehicle Control System (VCS)".
