For our senior project, we decided to make a universal blind spot detection mirror. Blind spot detection is a notable achievement for the development of user safety in automobiles. Building on this idea, the scope of this project is to design, test, and build a vehicle accessory as a replacement for existing mirrors which would have a built-in blind spot detection system. Many vehicles are not equipped with blind spot detection. Even on newer vehicles, blind spot detection only comes on certain trim packages. This makes a blind spot detection mirror an excellent option for both old classic cars as well as daily drivers. As a society, safety is an important goal and we are always trying to find a better, safer way to do things. The goal of this project is to contribute to automotive safety. Testing and experimenting with vehicle safety equipment will not happen on public roads nor is it in the scope of this project. All testing will be in a safe environment on school grounds. Testing will be mock road conditions and will be completed in a lab environment and not on moving vehicles. We have designed and prototyped a mirror housing with a sensor that indicates if a vehicle is in a blind spot. Subject: Mechanical Engineering, Computer Science
