1
Connecting Vehicles
  • Brice Lambi
  • National Center for Atmospheric Research
2
The Goal
  • Real-time maintenance data, vehicle location, vehicle trouble codes, fuel usage, emissions
  • Get real-time weather data, CAN bus, on-board vehicle sensors, third-party weather sensors
  • Feedback to the driver, treatment recommendations, weather forecasts
3
Choosing System Components
  • Single Board Computer or Mini Systems
    • Found in many AVL systems
    • Similar resources as a desktop computer
  • Telematics Platforms
    • Small form factor
    • Purpose built equipment
  • Off-the-shelf


4
Single Board Computers
  • Lots of inputs, good for interfacing with spreaders, sensors, etc.  Best for heavy duty equipment
  • On board storage, good for logging high resolution data
  • Reliable, full operating system allows for solid software and long-term operation, easy to attach display
  • If there is an existing AVL system, it may be possible to extend, add sensors
  • Expensive compared to telematics platforms
  • Larger footprint
5
Telematics Platforms
  • Small footprint, can ease installation and maintenance
  • Less expensive than full systems
  • Few inputs, best for light duty vehicles
  • Fewer computing resources, limitations to frequency of data
  • May not have data storage
  • Larger development costs


6
Off-the-shelf
  • Sometimes available as a package with service
  • May ease initial deployment
  • May not interface with other equipment
  • May come bundled with service contracts
  • May have functional limitations
  • Data may be proprietary
7
Data Services
  • Cellular
    • Cheap
    • Fast
    • Service may be spotty
    • Pay per KB or monthly subscriptions
  • Satellite
    • Expensive
    • Slow
    • Unreliable at times
    • Pay per KB
  • Packet Radio
8
Challenges
  • Implementation
    • Few off-the-shelf options
    • Custom development for interfacing with third-party systems (spreaders, sensors, etc.)
  • Deployment
    • Custom installations
    • Field testing
    • Data flow, getting real-time data into MDSS or VDT, getting data back to driver
