The invention relates to the field of vehicles, in particular to a vehicle speed limit early warning method and device, electronic equipment and a medium. The vehicle speed limit early warning method comprises the following steps: responding to road speed limit information of a road test unit; the road speed limit information comprises speed limit information; determining a speed limit early warning level according to the road speed limit information, the vehicle driving information, a preset vehicle speed threshold value and a preset overspeed interval database; the vehicle driving information comprises a vehicle position and a vehicle speed, and the vehicle position comprises a lane to which the vehicle belongs; and according to the speed limit early warning grade, controlling to send vehicle speed limit early warning prompt information. According to the method, a camera does not need to be adopted, the reliability of early warning is improved, the method does not depend on a map navigation APP, the flexibility is higher, the scheme of the method is simple, the real-time performance and accuracy of early warning can be guaranteed, lane-level speed limit early warning can be achieved, a driver is effectively reminded through speed limit early warning prompt according to the speed limit early warning level, and the driving safety is improved.

    本发明涉及车辆领域,具体而言,涉及一种车辆限速预警方法、装置、电子设备及介质。所述车辆限速预警方法包括:响应路测单元的道路限速信息;道路限速信息包括速度限制信息;根据所述道路限速信息、车辆行驶信息、预设车速阈值和预设超速区间数据库,确定限速预警等级;车辆行驶信息包括车辆位置和车速,车辆位置包括车辆所属车道;根据限速预警等级,控制发出车辆限速预警提示信息。该方法无需采用摄像头,提升了预警的可靠性,并且不依赖地图导航APP,灵活性更高,该方法方案简单,可保证预警的实时性和准确性,并且可实现车道级限速预警,根据限速预警等级进行限速预警提示有效提醒驾驶员,提高行驶安全性。
