Introduction
Are you afraid that your brand new Hummer is going to get scratched while parking it in a tight space? Do you have trouble backing your large Mercedez S-class into your small garage? Fear no more! Our ultrasonic ParKontroller can sense how far you are away from the wall or a hidden object behind your car and warn you visually and audibly using LEDs and speaker respectively.
High Level Design
Rationale of our project
A significant portion of the people around the world owns car or are daily drivers. In fact, United States alone has the largest passenger vehicle market in the world and there were over 243 million registered vehicles in the U.S. in 2004. Among these drivers, it’s not entirely untrue to assume that parallel parking or rearward parking is one of the most cumbersome parts of their driving experience. It takes years of driving experience and rigorous practices to avoid a fender bender or an ugly scratch across the bumper. Some old school auto-enthusiasts may like to do everything manually, but most of us like to take advantage of the advanced car electronics and technologies to make our life a little bit easier and also to avoid common accidents during parking. Hence, we decided to design and build an ultrasonic parking assistant system that will help the driver get a sense of how far his or her car is away from a wall or an object behind the car.
Conclusion
ParKontroller can detect an object within a range of 40cm with accuracy of 1cm in the distance interval of 15 to 40cm. If we were to do this project again, we would try to increase the effective range and enhance the accuracy by implementing some kind of noise reduction circuit. Furthermore, we would like to implement an array of ultrasonic receiver so that we can determine the location of the object with respect to the ultrasonic transmitter. Finally, usability of the ParKontroller can be improved by making it completely portable and attachable to the bumper of any commercial vehicles.
