  1. Project Forget-Me-Not TCSP8 Reliability and Safety Analysis ECE477 GROUP 4 CHRIS CADWALLADER CRAIG PILCHER ANDY SYDELKO MIKE WILLIAMS

  2. Reliability and Safety Concerns • False negative – Child present, but not detected • Could lead to physical harm or death • Unintended manipulation of host vehicle • Undesired CAN trasmissions • Component failure due to excessive heat • Overuse of the audio amplifier

  3. Components Likely to Fail • Freescale9S12DP256C– High complexity microcontroller • TAS5710 – Audio amplifier • Mounted upright, no heatsink • LM5705 – Linear regulator • Majority source of heat • Linxtranciever – Wireless module

  4. Mitigation of Safety and Reliability Issues

  5. Mitigation of Safety and Reliability Issues • Proper de-rating of components to increase reliability • Additional measures or handshaking to prevent child side detection misses due to RF interference. • Conservative use of the audio amplifier • Determine a detection method for failure of the RF interface

  6. Questions?
