Every year, automotive manufacturers introduce new technologies into their vehicles that increase efficiency and provide meaningful data to facilitate the diagnosis of potential safety or performance issues. Modern vehicles can sense when routine maintenance – such as brake, oil, or tire replacement - is necessary. Despite these technological advances, sensor systems still lack the ability to tell a user when wheel alignment is needed. Among other issues, misaligned wheels cause vehicles to handle unpredictably and increase tire wear.
Currently, consumers can only check their cars’ wheel alignments by making an appointment with a professional and paying for an alignment, which can range anywhere from $50 to hundreds of dollars. Our goal is to develop an alignment-sensing system that can be mounted on any vehicle by an average consumer. Such a system will enable users to determine if their vehicle(s) need an alignment while saving them time and money.
To implement such a system, we will mount an accelerometer and wireless transmitter to each wheel of a car. The data collected will be transmitted to a central hub attached to the chassis, consisting of a microcontroller for data processing and three additional accelerometers used as reference points to determine the camber, caster, and toe of a vehicle. Once alignment data is collected, it will be cross-referenced with a database of OEM alignment specifications for each manufacturer. Until this system is integrated into existing car diagnostic systems, alignment information will be available to users via a smart phone application.
While alignment detection systems already exist, they only appear in race cars where all sensors are mounted to the vehicle chassis. This system would not be feasible for consumer cars because a large percentage of them have been in accidents, meaning that the chassis can be warped and give inaccurate readings.

Environmental Sensing for Firefighters

Featured Project

Hyun Yi, Lauren White, and Andri Teneqexhi earned the Instructor's Award in the Fall of 2013 for their work on the Environmental Sensing for Firefighters.

"Engineering is all about solving real life problems and using the solutions to improve the lives of others. ECE 445 allows you to actually delve deeper into what this really means by providing students the chance to undergo the engineering design process. This requires taking all of the theoretical knowledge, lab experiences, and ultimately, everything that you have ever learned in life, and applying it to your project. Though, there is structure to the course and deadlines in place to measure your team's progress, the actual design, implementation, and success of your project is all determined by you. Unlike any other course that I have taken, I've gained an appreciation for the utilization and benefits of external resources, unforeseen scheduling delays, delegating tasks, and most importantly, teamwork. I consider ECE 445 to be a crash course into real life engineering and a guide to become a successful engineer." -- Lauren White
