The invention provides a road icing early warning method, device and equipment and a readable storage medium, and the method comprises the steps: detecting whether a vehicle is in a low-temperature icing environment or not when the rotating speed of an output shaft is greater than a preset rotating speed and/or a high-voltage signal of the whole vehicle is in a ready state; if the vehicle is in the low-temperature icing environment, outputting an early warning prompt that the vehicle is in the low-temperature icing environment; acquiring the rotating speed change rate, the vehicle speed and the slip rate of the output shaft; the driving road condition of the vehicle is determined according to the rotating speed change rate of the output shaft, the vehicle speed and the slip rate; and if the vehicle is in the road icing condition, outputting an early warning prompt that the vehicle is in the road icing condition. According to the invention, a driver can be reminded of a road icing risk when the vehicle is started and driven, and major traffic accidents are prevented.

    本发明提供一种道路结冰预警方法、装置、设备及可读存储介质,包括:当输出轴的转速大于预设转速和/或整车高压信号处于ready状态时,检测车辆是否处于低温结冰环境;若车辆处于低温结冰环境,则输出车辆处于低温结冰环境的预警提醒;获取输出轴的转速变化率、车速和滑移率;根据所述输出轴的转速变化率、所述车速和所述滑移率确定车辆的行驶路况;若车辆处于道路结冰路况,则输出车辆处于道路结冰路况的预警提醒。通过本发明,可以在车辆启动时及行驶中提醒驾驶员有道路结冰风险,预防重大交通事故发生。
