Method and System for Identifying Wet Pavement Using Tire Noise |
摘要 |
A wet road surface detection system is provided for a vehicle driving on a road. The wet road surface detection system includes a sound sensing device coupled to the vehicle for capturing noise of the vehicle tires as the vehicle drives on a road surface. A processor processes sounds captured by the audible sensing device. The processor quantifies a variable sound level of the captured noise between a first frequency and a second frequency. The processor determines whether each quantified sound level between the first frequency and the second frequency is above a predetermined sound level threshold below the sound level at the first frequency. The processor determines that the vehicle is driving on a wet road surface in response to each quantified sound level between the first frequency and the second frequency being above a predetermined sound level threshold below the sound level at the first frequency.
