The invention relates to an automobile pavement information recognition method and device, a vehicle and a storage medium, and the method comprises the steps: collecting the driving data of the vehicle, and judging the current driving condition of the vehicle based on the driving data of the vehicle; if the current driving working condition of the vehicle is a first preset working condition, calculating a first parameter of a road surface according to the driving data of the vehicle, calculating a first adhesion coefficient based on the first parameter and a first preset strategy, and if the current driving working condition of the vehicle is a second preset working condition, calculating a second parameter of the road surface according to the driving data of the vehicle, obtaining a second adhesion coefficient based on a second parameter and a second preset strategy, and filtering the first adhesion coefficient or the second adhesion coefficient to obtain a final adhesion coefficient value; and by taking the final attachment coefficient value as an index, searching a preset standard road condition attachment coefficient-road condition information relation table to obtain the current road condition information of the road surface, so that the hardware cost is saved, and the attachment coefficient identification precision and the driving condition coverage are effectively improved.

    本申请涉及一种汽车路面信息的识别方法、装置、车辆及存储介质,其中,方法包括:采集车辆的行驶数据,并基于车辆的行驶数据判断车辆当前行驶工况;若车辆当前行驶工况为第一预设工况,则根据车辆的行驶数据计算路面的第一参数,基于第一参数和第一预设策略计算第一附着系数,若车辆当前行驶工况为第二预设工况,则根据车辆的行驶数据计算路面的第二参数,基于第二参数和第二预设策略得到第二附着系数,并对第一附着系数或第二附着系数进行滤波,得到最终附着系数值;以最终附着系数值为索引,查找预设标准路况附着系数‑路况信息的关系表,得到路面的当前路况信息,从而在节省硬件成本的同时,也有效提高了附着系数识别精度和行驶工况覆盖度。
