Automotive Security Integration

Modern passenger cars typically include some degree of security. Unfortunately it is sometimes not enough to deter some thieves. Automotive security in the early 2000’s often consisted only of an alarm system which triggers when a door is opened while the system is armed. This means that windows can be broken without triggering it. It also means that the car may be lifted to have the wheels stolen. The purpose of this project was to integrate additional security system peripherals into a factory alarm system, with no additional steps for the owner to use.

The target vehicle’s schematics were carefully studied to understand how the alarm system is armed and triggered. Additionally, aftermarket sensors were also tested. Once the system was characterized, a circuit was designed to integrate the aftermarket components with the factory system without disturbing it. The sensors were carefully installed along with the necessary electronics. Deploying this system now causes the car alarm to be activated when any of the windows are broken, if the vehicle is impacted, or if the vehicle is tilted.
