  1. Small Business Innovation Research: A Deployable Wireless Architecture for Sensor-Based Embedded Diagnostics and Prognostics on Ground Vehicles SBIR #A01-226 June 10, 2003Michael Losh, VP Core Technology American Systems Technology Incorporated

  2. ASTI • Founded in 1992 • Background: delivering embedded software and tools for automotive controls development to OEMs and first-tier suppliers • 8(a)-certified by SBA, 6 years of eligibility remaining • Headquarters in Troy, Michigan. ASTI 2003

  3. “Micromachine for Diagnostics” SBIR Background • Small Business Innovation Research • Sponsored by National Automotive Center in TARDEC • COTR: Andrew Scott, TARDEC Robotics Mobility Laboratory • Phase II commenced 2/14/03 ASTI 2003

  4. Program Vision • TARDEC expressed interest in a “MEMS chip” that can be targeted to multiple diagnostic and prognostic applications on the vehicle and produced in high volumes • MEMS = Micro Electro-Mechanical Systems • ASTI added wireless digital communications as a critical element of an embedded diagnostics architecture ASTI 2003

  5. Motivations Embedded Diagnostics and Prognostics Readiness Sustainability Safety Longevity FCS BCT Legacy Commercial Performance Commercial Trends ASTI 2003

  6. An Embedded Diagnostics and Prognostics Architecture Why an “architecture”? • Everything essential has its place • Elements are arranged to work well together • Design can be altered to fitclient/customer’s needs • Provisions for future additions ASTI 2003

  7. Challenges to an Embedded Diagnostics and Prognostics • Premise: dedicated sensors will improve diagnostic and prognostic capability. • How to integrate more and more sensors (MEMS and conventional) at reasonable cost and complexity?  Wireless communication inside the vehicle (AKA “cable replacement”) • How to effectively present diagnostic and prognostic alerts to vehicle operators? Vehicle bus integration, graphical displays • How to efficiently communicate diagnostic and prognostic results to maintainers and the logistics community? Vehicle bus integration  Wireless communication outside the vehicle (e.g. Bluetooth) ASTI 2003

  8. Sensor + RF Sensor + RF ASTI’s Wireless Embedded Diagnostics Architecture High-Freq RF Data Link (~2.4 GHz) Low-Freq RF (~300 MHz) Maintainer Interface ))) ))) Decoupled sensors, wireless connection ))) Driver Information Interface Low RF Receiver High RF Trans-ceiver Signal Con-ditioning Control and Analysis Electronic Control Module Sensor Sensor Signal Con-version Data Bus Trans-ceiver Decoupled sensors, wired connection Sensor Sensor Sensor Physically attached sensors, direct signal Vehicle Data Bus J1708, J1939, etc. ASTI 2003

  9. Integration with Vehicle & World Portable hand-held diagnostic scanner and data collection tool with RF transceiver Data forwarded to commanders, maintenance depots, logistics, PMs, etc. Telematics & diagnostics display, user input RF or wired link CLOE*, other Data networks Detached sensors with wireless or wired link ))) Vehicle data bus J1939, J1708, etc. Detached sensors connected through vehicle data bus ))) Plug-in diagnostic equipment (e.g. SPORT) ))) Embedded Diagnostics Platform with attached Sensor(s) * CLOE = Common Logistics Operating Environment ASTI 2003

  10. SBIR Program Phases • Phase I: Conceptual design & feasibility study • Phase II: Detailed design, simulation, prototype fabrication, laboratory evaluation • Phase II-Plus: Demonstrate additional diagnostic and prognostic applications, prepare for pilot production • “Phase III”: Initial production and commercialization ASTI 2003

  11. Demonstration Concept Diesel Powertrain Lubricant Condition Monitor on M915 or similar • Diagnostic Objectives: • Detect unfit engine lubricant conditions • Detect water or coolant contamination • Detect abnormal lubricant loss • Detect plugged oil filter • Sensors: • Electrical conductivity / dielectric impedance • Temperature • Lubricant level • Soot concentration • Lubricant pressure ASTI 2003

  12. Additional Application Concepts • Hydraulic Lifting System Fluid Condition Monitor • Air Intake Dust Monitor • Suspension System Condition Monitor • Battery Charge Monitor ASTI 2003
