Final System

Final System

   Combining the previous steps together we came up with a final system that could sense the deceleration rate of a vehicle and pulse a set of LED's when the deceleration was higher than the pre-set threshold. The row of LED's simulated a high mound stop light of a vehicle. The prototype system utilized a normally open relay but a real world system would use a single pole double throw relay so that when no current was coming from the adaptive brake light circuit,it would be closed and the brake lights would work as normal.

This is our final prototype system assembled:

This system has a lot of room for improvement but this is what we came up with in the end. Due to legal standards in New Zealand the brake lights of a vehicle have to emit a solid light. However, hazard lights are a widely recognized signal for danger and are meant to flash. Therefore, if we were to put this system on the market we would be using the hazard light system instead of the brake lights. We would also used a small computer chip to control the system as it would only need to be programmed to run the system and then wired in. The system would also be contained in a small box with the appropriate power and relay wires exposed for installation. A level would also be incorporated on top of the box so that the installer can make sure the system is level and will operate as intended.
