Techniques are described for estimating road friction between a road and tires of a vehicle. A method includes receiving, from a temperature sensor on a vehicle, a temperature value that indicates a temperature of an environment in which a vehicle is operated, determining a first range of friction values that quantify a friction between a road and tires of a vehicle based on a function of the temperature value and an extent of precipitation in a region that indicate a hazardous driving condition, obtaining, from the first range of friction values, a value that quantifies the friction between the road and the tires of the vehicle, wherein the value is obtained based on a driving related behavior of the vehicle, and causing the vehicle to operate on the road based on the value obtained fromthe first range of friction values.
描述了用于估计道路与车辆的轮胎之间的道路摩擦力的技术。一种方法包括:从车辆上的温度传感器接收指示车辆在其中操作的环境的温度的温度值;基于温度值和指示危险驾驶状况的区域中的降水程度的函数,确定对道路和车辆的轮胎之间的摩擦力进行量化的摩擦力值的第一范围;从摩擦力值的第一范围中获得对道路和车辆的轮胎之间的摩擦力进行量化的值,其中所述值是基于车辆的驾驶相关行为而获得的;以及使得车辆基于从摩擦力值的第一范围中获得的所述值来在道路上操作。
