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.

    本发明涉及一种路况判定设备、路况判定方法和计算机可读存储介质,其中,该路况判定设备包括获取模块,其配置成用于获取车辆各车轮的轮心垂向加速度信号;预处理模块,其布置在所述获取模块的后级,并且配置成用于对所述轮心垂向加速度信号进行预处理以获得可表征其波动情况的初始判定信号;高通滤波器,其布置在所述预处理模块的后级,并且配置成用于以高通滤波因子对所述初始判定信号进行高通滤波;低通滤波器,其与所述高通滤波器并行地布置在所述预处理模块的后级,并且配置成用于以低通滤波因子对所述初始判定信号进行低通滤波;确定模块,其配置成用于基于低通滤波后的初始判定信号以及高通滤波后的初始判定信号确定路况系数。
