One or more embodiments of the present specification provide a road guidance method and system in rainstorm weather, by obtaining detection information of a vehicle safety wading depth and a water level detection point, an alternative initial route between a current position and a destination position of a vehicle is generated, the alternative initial route is sorted, and whether the road sectionswith the water level heights exceeding the safe wading depth of the vehicle exist on the initial route or not is sequentially judged according to the sequence, so that the recommended route is output, potential safety hazards brought to the vehicle when the vehicle travels to the road sections with the deep water depth in rainstorm weather can be avoided, the recommended route with short traveling time or short traveling mileage can be provided as much as possible, and the driving efficiency is improved.

    本说明书一个或多个实施例提供一种暴雨天气下的道路引导方法及系统,通过获取车辆安全涉水深度,和水位检测点的检测信息,生成车辆当前位置与目的地位置之间的备选初始路线,并对备选初始路线进行排序,按排序依次判断初始路线上是否存在水位高度超过车辆安全涉水深度的路段,从而输出推荐路线,能够既避免车辆在暴雨天气下行驶到水深较深的路段,给车辆带来安全隐患,又能尽可能提供行驶时间较少或行驶里程较短的推荐路线,提高行驶效率。
