SENIOR Design Project

Introduction

Traditional vehicle sun visors provide limited coverage and often require manual adjustment while driving, which can distract the driver and still fail to adequately block sunlight from different angles. Sun glare may reduce visibility, cause eye strain, and temporarily impair a driver’s vision, creating potential safety concerns during vehicle operation.

This project proposed an adaptive sun-position tracking visor system capable of automatically repositioning a light-filtering panel across a vehicle windshield in response to changing sunlight conditions. By combining sensors, software-based control systems, and motorized positioning mechanisms, the system was designed to reduce glare while maintaining driver visibility and improving overall driving safety and comfort.

Design process

At the start of the challenge, as a team, we were tasked to generate various needs ideas, and after narrowing them down to a lot of possible candidate ideas, the final idea we decided to pursue was the tracking visor system that would reduce sun blindness.

After a lot of conversation we derived to the following fuctional requiremnets

x-y coordinate motion of visor within the frame
Have a 200ms latency
Have a moving vidor of 250 mm/s

Usage of a singular visor.
Adaptable windshield size
Aesthetically Unobstrusive

By combining sensor systems, software-based control algorithms, and motorized positioning assemblies, the proposed design aimed to create a dynamic filtering system capable of automatically responding to changing sunlight conditions in real time.

Conclusion

Although a fully functional prototype was not achieved, the project successfully established the conceptual framework, mechanical architecture, and software control strategy required for implementation. The development process also identified several potential improvements and future innovations that could significantly enhance the effectiveness, reliability, and practicality of the system.

Overall, the project demonstrated the feasibility of an intelligent vehicle glare-reduction system capable of improving driver comfort, visibility, and road safety through adaptive sunlight filtering technology.
