INTRODUCTION 3

Background of ICE – the US Army’s TWV APTS The US Army has developed a test platform, termed the ICE (Internal Combustion Engine) kit or system, for the maintenance of their fleet of tactical wheeled vehicles (TWVs). 4

Background of ICE – the US Army’s TWV APTS The ICE system is consisting of: 1. TWVs vehicle network(s) 2. The vehicle analog data port 3. Multi-meter capability 4. Various transducers and cables 5. Software manages vehicle data 5

After ICE The ICE system has offered important pointers for the future of computer based vehicle maintenance systems. 6

After ICE 1. Size and weight reduction 2. Alternatives to wired connections improving 3. Integration of applications 4. Support for new fleet maintenance 7

THE NEW DIRECTION-SWICE 8

The new direction-SWICE The Smart Wireless ICE (SWICE) program is vehicle embedded health monitoring and diagnostic systems for TWVs. 1. Lose the Wires 2. Weight-Loss Program 3. Go Commercial 4. Software Integration 5. SWICE Support of CBM & CLOE 6. SWICE & Prognostics 9

1. Lose the Wires 10

2. Weight-Loss Program The Smart Wireless Diagnostics Sensor (SWDS) consisting of a CEP (Common Electronics Package). Several VCAs(Vehicle Connector Assemblies) can be attached to the CEP. 11

3. Go Commercial To enable this integration, a wireless adapter designed that attaches to the Digital Multi- Meter (DMM) and becomes an integral part of the SWICE. 12

4. Software Integration 13

4. Software Integration The DS provides capabilities for: Vehicle identification Vehicle fault detection and analysis Vehicle data monitoring(digital and analog) Vehicle data archiving Special test routines Data forwarding for fleet maintenance 14

5. SWICE Support of CBM & CLOE 15 Common logistic operating environment(CLOE) Condition Based Maintenance(CBM)

5. SWICE Support of CBM & CLOE The SWDS’s CEP is designed with CBM &CLOE Monitor the vehicle network Monitor the analog diagnostics signals Process and archive the data Provide visual indication of vehicle faults Communicate with external applications over wired or wireless links Host CBM+ and CLOE applications and more 16

6. SWICE & Prognostics The SWDS will implement a Prognostics Host with a published specification for designing prognostics modules that can then be hosted on the SWDS. It will also provide a framework for the prognostics module. 17

FINAL THOUGHTS AND THE MINI-VCS 18

Final thoughts and the MINI-VCSS The SWICE effort capitalizes on the lessons learned from the previous ICE and WICE (Wireless ICE) solutions and incorporates state-of-the-art technologies to meet the stated goals of the today’s and future diagnostics solutions. 19
