“Sonic Parking” – Final Year Project

Each student studying electronics at LTU must complete a final year design project to demonstrate design skills and electronic knowledge they have acquired. The project I undertook was, “Sonic Parking.”

Sonic Parking was a reverse parking aid that used ultrasonic ranging at four points across a vehicles rear bumper to measure distance between the bumper and the closest object to the vehicle and the measured distances would then be displayed on a LCD screen positioned within the drivers view.

The finished product had the following features:
- Capable of measuring from 0.4 to 9.7 meters with a overall accuracy ±0.1 meters
- Four point location resolution
- Range resolution of 0.1 meters
- Flashing LED/beeper where frequency increase as closest object

The project presentation slides and thesis of Sonic Parking can be viewed here!
