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

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

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 MultiMeter (DMM) and becomes an integral part of
the SWICE.

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


Common logistic operating environment(CLOE)
Condition Based Maintenance(CBM)
15
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 .

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.
