  1. ECE 477 Final Presentation Team 4  Fall 2010 Mike Williams Chris Cadwallader Andrew Sydelko Craig Pilcher

  2. Outline • Project overview • Block diagram • Design challenges • Individual contributions • Project demonstration • Questions / discussion

  3. Project Overview • A child safety-system that prevents parents and caretakers from accidentally leaving children in vehicles. • Average number of U.S. child hyperthermia fatalities per year since 1998: 37 • 49 so far in 2010 alone (8 since start of project) • Goal is to prevent as many deaths as possible • System tracks presence of children in safety seats and can control the car’s systems to save the child’s life

  5. Car Side Block Diagram

  6. Child Side Block Diagram

  7. Design Challenges • Detection of vehicle state varies widely across car models from 1996 to 2010. • SWCAN, J1850, ISO9141, etc. supported • Required simultaneous CAN control, audio playback, vehicle state detection, and wireless monitoring • Control of vehicle depends on imitation of internal components and keyfob • Non-linear memory layout

  8. Individual Contributions • Team Leader – Mike Williams • Team Member 2 – Chris Cadwallader • Team Member 3 – Craig Pilcher • Team Member 4 – Andrew Sydelko

  9. Team Leader – Mike Williams • Board and Software Design • Initial Component Selection and Schematic • Soldering (poorly)

  10. Team Leader – Mike Williams

  11. Member 2 - Chris Cadawallader • Software Design • Drivers • CAN communication • Child side detection • State Machine • Verification

  12. Member 3 - Craig Pilcher • Software Design • Organization • Development • Debugging • Audio, CAN fxns • Component Selection

  13. Member 4 - Andrew Sydelko • Software/hardware troubleshooting • PWM audio, FLASH access from CodeWarrior • Packaging design and implementation • Software design

  14. Project Demonstration • An ability to determine the operating state of the vehicle via the OBD-II port.  • An ability to determine the presence of a child in a safety seat.  • An ability to use multiple safety seats in one vehicle.  • An ability to sound an audible alarm when the ignition is turned off.  • An ability to interface directly to the internal vehicle CAN.
