The invention discloses a method for determining a road adhesion coefficient required by vehicle braking control. The method comprises the steps that vehicle end equipment uploads information of a road section where a vehicle is located currently and weather information of the road section where the vehicle is located currently to a cloud server; the cloud server queries a road adhesion coefficient database to obtain a corresponding road adhesion coefficient; the cloud server issues the corresponding road adhesion coefficient to the vehicle end equipment, and the vehicle end equipment takes the corresponding road adhesion coefficient as a road adhesion coefficient required by vehicle braking control, wherein the road adhesion coefficient database is a corresponding relation table of road section information, weather information and road adhesion coefficients; when the ABS or the TCS is activated, the vehicle end equipment uploads the current road adhesion coefficient f, the information of the current accurate road section of the vehicle and the weather information of the current road section of the vehicle to the cloud server, and the cloud server updates the road adhesion coefficient database. According to the invention, the real-time and accurate road adhesion coefficient can be obtained.

    本发明公开了一种车辆制动控制所需路面附着系数的确定方法,包括:车端设备将车辆当前所处的路段信息和车辆当前所处路段的天气信息上传到云端服务器;云端服务器查询路面附着系数数据库,得到对应的路面附着系数;云端服务器将对应的路面附着系数下发给车端设备,车端设备将该对应的路面附着系数作为车辆制动控制所需路面附着系数;其中,路面附着系数数据库为路段信息、天气信息与路面附着系数的对应关系表;当ABS或者TCS激活时,车端设备将当前路面附着系数f、车辆当前所处的精确的路段信息以及车辆当前所处路段的天气信息上传至云端服务器,云端服务器更新路面附着系数数据库。采用本发明能得到实时准确的路面附着系数。
