The invention belongs to the technical field of automobile driving, and provides a heavy-duty automobile curve speed early warning method and system, and the method comprises the steps: obtaining a road curvature radius at a preset distance S on a driving road in front of an automobile in real time based on a vehicle-mounted map and the current position information of the automobile; calculating the current actual gravity center height of the vehicle in real time; based on the road curvature radius and the actual gravity center height in real time, the curve early warning speed and the curve early warning distance corresponding to the vehicle at present are calculated; and performing curve speed early warning and curve early warning distance early warning on the vehicle based on the current vehicle speed, the preset distance S and the curve early warning speed and curve early warning distance corresponding to the vehicle at present. The curve speed early warning system is used for solving the problems that an existing curve speed early warning system is high in cost, short in recognition distance and not high enough in heavy-duty car alarm precision.

    本发明属于汽车驾驶技术领域,提供一种重型汽车弯道速度预警方法及系统,均能够:基于车载地图和车辆当前所处位置信息,实时获取车辆前方行驶道路上预设距离S处的道路曲率半径;实时计算车辆当前的实际重心高度;实时基于所述道路曲率半径和所述实际重心高度,计算车辆当前对应的弯道预警速度和弯道预警距离;基于车辆当前车速、预设距离S以及车辆当前对应的弯道预警速度和弯道预警距离,对车辆进行弯道速度预警和弯道预警距离预警。本发明用于解决现有弯道速度预警系统成本高、识别距离短以及对重型汽车报警精准度不够高的问题。
