Abstract

The present invention provides a fast re-planning method in navigation. The fast re-planning method in navigation comprises the following steps of: the step 101: performing normal planning and navigation, after the planning is completed, storing route related information in a cache after the planning is completed, and performing navigation according to the location information; the step 102: determining whether a re-planning condition is met or not; the step 103: determining whether a fast re-planning condition is met or not; and the step 104: re-planning an expansion method. Through the abovesteps, it is achieved that during the navigation process, when a deviation route is recognized, the route to the destination can be quickly re-planned.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a fast re-planning method in navigation. Background technique [0002] Along with the continuous development of science and technology, the navigation system with vehicle navigation function emerges at the historic moment. The navigation system can plan the route for the user, and can use the global positioning system (GPS) chip to obtain the moving track in real time, and then determine the position of the vehicle on the road of the traffic vector map. At present, the navigation system has a variety of navigation strategies when planning routes, such as the fastest time, the shortest path, avoiding high speed, avoiding congestion, etc. Once the user chooses a certain navigation strategy, the navigation system will always be based on The navigation strategy selected by the user plans a route for the user. However, if the user deviates from the established navigation route du...
