The invention discloses a vehicle-mounted terminal localization segmented speed limit judgment method and a vehicle-mounted terminal. The method comprises the following steps: acquiring GPS information of a vehicle-mounted terminal; loading a configuration file containing the GPS feature points and the speed limit value of the speed limit road section; calculating the distance from the vehicle to the speed limit road section; judging whether the distance is smaller than a threshold to determine whether to enter a speed-limiting road section; and if so, acquiring a speed limit value, judging whether the speed is overspeed or not, and performing corresponding processing. According to the method, loading of an intelligent map and localized judgment are not needed, resource consumption is reduced, real-time performance is improved, cost is reduced, and the method is suitable for accurate speed limit management of buses and other vehicles.

    本发明公开了一种车载终端本地化分段限速判断方法及车载终端。该方法包括:获取车载终端GPS信息;加载包含限速路段GPS特征点和限速值的配置文件;计算车辆到限速路段的距离;判断距离是否小于阈值以确定是否进入限速路段;若进入,则获取限速值并判断是否超速,进行相应处理。本发明无需加载智能化地图,本地化判断,降低资源消耗,提高实时性,降低成本,适用于公交等车辆的精准限速管理。
