The invention discloses a road network information construction method of a vehicle and a driving prompting method of the vehicle. The method comprises the following steps: acquiring current position information of a vehicle and a target road in front of the current driving of the vehicle; local map information, corresponding to the current preset range, of the vehicle is called according to the current position information, and the local map information is used for representing road information of related roads in the current preset range; constructing a tree structure of related roads in a current preset range and a linked list structure of a target road based on the local map information; road network information of the vehicle is constructed based on the tree structure and the linked list structure, and the road network information is used for prompting the road state for the vehicle in the vehicle driving process. According to the invention, the technical problem of high difficulty in constructing vehicle road network information is solved.
本发明公开了一种车辆的路网信息构建方法及车辆的驾驶提示方法。其中,该方法包括:获取车辆的当前位置信息和车辆当前行驶前方的目标道路;根据当前位置信息调取车辆对应当前预设范围内的局部地图信息,其中,局部地图信息用于表示当前预设范围内所涉及道路的道路信息;基于局部地图信息构建当前预设范围内所涉及道路的树结构和目标道路的链表结构;基于树结构和链表结构构建车辆的路网信息,其中,路网信息用于在车辆行驶过程中为车辆提示道路状态。本发明解决了构建车辆路网信息的难度较大的技术问题。
