The invention provides a path planning method, device and system for automatic parking, a vehicle and a medium. The method comprises the following steps: acquiring a current coordinate; performing automatic planning according to a preset preference parameter to obtain an end point coordinate; acquiring preset map data according to the path planning instruction; generating a directed topological graph according to preset map data; according to a search algorithm, matching the directed topological graph with the current coordinate and the end point coordinate to obtain a global topological path; extracting a target path point of the global topological path; and outputting an automatic parking path according to the user configuration information and the target path point. According to the method, the terminal point can be customized according to user requirements, the automatic planning of the automatic parking path of the vehicle is realized according to the current coordinate and the terminal point coordinate of the vehicle, and the directed topological graph can be generated through the preset map data for path planning, so that the limitation of different map data formats on the automatic parking path planning is eliminated.

    本申请提供了一种自动泊车的路径规划方法、装置、系统、车辆及介质。其中方法包括:获取当前坐标;根据预设偏好参数进行自动规划,得到终点坐标;根据路径规划指令,获取预设地图数据;根据预设地图数据生成有向拓扑图;根据搜索算法,以当前坐标和终点坐标对有向拓扑图进行匹配,得到全局拓扑路径;提取全局拓扑路径的目标路径点;根据用户配置信息和目标路径点输出自动泊车路径。本方法可以根据用户需求对终点进行定制,并根据车辆的当前坐标和终点坐标实现对车辆自动泊车路径的自动规划,还可以通过预设地图数据生成有向拓扑图进行路径规划,以摆脱不同的地图数据格式对自动泊车路径规划的限制。
