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

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
