The invention discloses a vehicle transportation safety risk early warning method, device and equipment and a medium, and relates to the technical field of vehicle safety. The method comprises the following steps: based on current positioning information of a vehicle, judging whether a curve road section with a curvature radius smaller than a preset radius exists in front of the vehicle; if the curve road section with the curvature radius smaller than the preset radius exists in front of the vehicle, estimating the transverse friction coefficient of the curve road section based on the meteorological data of the area corresponding to the positioning information; based on the curvature radius of the curve road section, the transverse friction coefficient and the cross section direction gradient corresponding to the curve road section, determining a first vehicle speed when the vehicle has the sideslip risk; if the current vehicle speed of the vehicle is larger than a second vehicle speed, early warning prompt information is sent to prompt a driver to reduce the vehicle speed, the second vehicle speed is determined based on the first vehicle speed, and the second vehicle speed is smaller than the first vehicle speed. According to the vehicle transportation safety risk early warning method, device and equipment and the medium, the vehicle transportation safety can be guaranteed.
本发明公开了一种车辆运输安全风险预警方法、装置、设备及介质,涉及车辆安全技术领域。该方法包括:基于车辆当前的定位信息,判断车辆前方是否存在曲率半径小于预设半径的曲线路段;如果车辆前方存在曲率半径小于预设半径的曲线路段,则基于定位信息所对应区域的气象数据,估算出曲线路段的横向摩擦系数;基于曲线路段的曲率半径、横向摩擦系数以及曲线路段所对应的横断方向坡度,确定出车辆发生侧滑风险的第一车速;如果车辆的当前车速大于第二车速,则发出预警提示信息以提示驾驶员降低车速,其中第二车速是基于第一车速确定的,且第二车速小于第一车速。本发明公开的车辆运输安全风险预警方法、装置、设备及介质可保障车辆运输安全。
