The invention relates to road condition judgment equipment, a road condition judgment method and a computer readable storage medium, and the road condition judgment equipment comprises an acquisition module which is configured to be used for acquiring a wheel center vertical acceleration signal of each wheel of a vehicle; the preprocessing module is arranged at the rear stage of the acquisition module and is configured to be used for preprocessing the wheel center vertical acceleration signal so as to obtain an initial judgment signal capable of representing the fluctuation condition of the wheel center vertical acceleration signal; the high-pass filter is arranged at the rear stage of the preprocessing module and is configured to perform high-pass filtering on the initial judgment signal by a high-pass filtering factor; a low-pass filter arranged in parallel with the high-pass filter at a post-stage of the pre-processing module and configured to perform low-pass filtering on the initial decision signal with a low-pass filtering factor; and a determination module configured to determine a road condition coefficient based on the initial determination signal after low-pass filtering and the initial determination signal after high-pass filtering.
