The invention relates to an attachment coefficient determination method and device and a storage medium. The method comprises the following steps: according to an attachment coefficient reference value of a target road section uploaded by a vehicle within a first preset duration, determining an attachment coefficient which corresponds to the target road section and is used for being shared with the vehicle; and gradually increasing the attachment coefficient which is used for being shared with the vehicle and corresponds to the target road section to the maximum historical attachment coefficient of the target road section within a second preset duration. Therefore, the determined adhesion coefficient is general information and can be applied to other vehicles. The drivers of other vehicles can obtain the adhesion coefficient of the target road section in advance and make corresponding control in advance, so that the driving safety of the drivers is improved. And the problem that the adhesion coefficient determined before is not applicable due to the fact that the adhesion coefficient of the road surface is affected by other factors (such as sunlight and wind power) can be avoided, and unnecessary energy consumption of follow-up passing vehicles for skid prevention is avoided.

    本公开涉及一种附着系数确定方法、装置和存储介质。该方法包括:根据车辆在第一预设时长内上传的目标路段的附着系数参考值,确定用于共享给车辆的对应该目标路段的附着系数;在第二预设时长内逐步将用于共享给车辆的对应该目标路段的附着系数增大至该目标路段的最大历史附着系数。如此,确定出的附着系数为通用信息,可以适用于其他车辆。其他车辆的驾驶员可提前获取目标路段的附着系数,预先做出相应的控制,以提高驾驶员的驾驶安全。并且可以避免因路面的附着系数受到其他因素的影响(如日照、风力等),导致之前确定的附着系数不再适用的问题,以避免后续经过的车辆为了防滑进行不必要的能量消耗。
