Ice detection on a road by analyzing tire to road friction ultrasonic noise
Keywords:
ice, ultrasonic noise, tire friction.Abstract
A preliminary investigation of black ice on a road detection technique was performed. This technique is based on the assumption that it might be possible to judge about the presents of the ice from tire to road friction ultrasonic noise. The system was built and installed in a test car to measure the ultrasonic noise in a 20 to 120 kHz spectrum range. Multiple experiments were performed at different road conditions with and without ice at various speeds. An increase of ultrasonic noise amplitude was found on icy surface in all informative spectrum range.Downloads
