BackgroundAccording to the Edmonton Police Service, on average 30 hit and run collisions are reported daily. This implies that almost 11,000 hit and run collisions occur yearly.
We have designed an add-on device that temporarily impairs a vehicle after a significant collision.
Immobilization Procedure (How it works)
Ø Device is capable of detecting vehicle speed & calculating the change in speed every 500ms
Ø Device will detect if a crash has occurred (change in speed > 22km/h)
Ø Device uses LED’s to display different modes of the vehiclev Green – Device is poweredv Yellow – Device is connected to the vehiclev Red – Vehicle has been immobilized and
will remain red until authorized personal has given approval
Ø RFID module is connected to the device as the unlocking mechanism
We would like to thank Dr. Michael Lipsett, Alan Lim, Peng Zhuang and Loren Wyard-Scottfor their help and support throughout the course of this project.
In order to be compatible for the device, the vehicle must meet the following requirements:
Ø Vehicle must be newer than 1996
Ø Must be either a gasoline or diesel engine vehicle
Ø A two-factor unlocking mechanism can be implemented – a combination of a pin code that can be entered through a mobile application and the RFID tag.
Ø With more cars becoming electric and hybrid, this device can also be implemented in such vehicles with a few minor changes.
