The invention provides a ramp speed limit mark display method and system, electronic equipment and a storage medium, and the method comprises the steps: obtaining a planned path and a current position of a target vehicle through a navigation map when a speed limit mark of a ramp is recognized; according to the current position and the planned path, whether the ramp is on the planned path is judged, and a judgment result is obtained; when the judgment result is that the ramp is on the planned path, obtaining the distance from the current position to the ramp; and when the distance is smaller than a preset threshold value, the speed limit mark is displayed in the target vehicle. According to the method, the planned path and the current position of the target vehicle are obtained through the navigation map, and when it is judged that the ramp appears on the planned path and the distance between the current position and the ramp is smaller than the preset threshold value, the speed limit mark is displayed, and the speed limit is displayed. Therefore, whether the display mark of the ramp is displayed or not is judged according to the actual driving route of the target vehicle on the navigation map, and the problem that an existing ISA system gives wrong reminding when passing through the ramp is solved.
本发明提供一种匝道限速标示显示方法、系统、电子设备及存储介质,方法包括:在识别到匝道的限速标示时,通过导航地图获取目标车辆的规划路径和当前位置;根据当前位置和规划路径,判断匝道是否在规划路径上,得到判断结果;在判断结果为匝道在规划路径上时,获取当前位置至匝道的距离;在距离小于预设阈值时,将限速标示在目标车辆中显示。本发明方法通过导航地图获取目标车辆的规划路径和当前位置,在判定上述匝道出现在上述规划路径上时,根据当前位置和匝道的距离小于预设阈值时,显示上述限速标示,从而实现了通过导航地图目标车辆的实际行驶路线来判断是否显示匝道的显示标示,降低了现有ISA系统经过匝道时给出错误提醒的问题。
