Abstract:
A method that detects whether the vibration level of the wheel is within the resonating frequency range by utilizing discrete velocity measurements. The method includes continuously measuring velocity levels of a wheel relative to a sprung mass vehicle component. These measurements are continuously recorded over a period of time. A periodic algorithm is provided, and the periodic algorithm and the velocity measurements are utilized to determine an output value. The output value is utilized to determine whether the vibration level of the wheel is within the resonating frequency range.
