Abstract
Path planning for mobile machine in large scale navigation disclosed. A path for moving a mobile machine is planned by: determining a start map node in a map graph based on a start point in the path and a goal map node in the map graph based on a goal point in the path; determining whether the start map node and the goal map node correspond to the same submap; and if so, planning the path between the start point and the goal point using a real-time path planning method; otherwise, obtaining the path between the start point and the goal point by merging a node path between the start map node and the goal map node, a first real-time path between the start point and a first stop point, and a second real-time path between the goal point and a last stop point.
