Embodiment Construction

[0025] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0026] The computer equipment includes user equipment and network equipment. Wherein, the user equipment includes, but is not limited to, computers, smart phones, PDAs, etc.; Or a cloud composed of network servers, among them, cloud computing is a kind of distributed computing, a super virtual computer composed of a group of loosely coupled computer sets.

Abstract

The invention provides a navigation path planning method and device. The method comprises the following steps: performing route calculation from a starting place to a destination according to a path calculation request to acquire at least one navigation route from the starting place to the destination; if detecting a road which path calculation should avoid, marking a passing cost punishment weight for the road; according to the passing cost punishment weight marked by the road, adjusting the passing cost of the navigation paths containing the road; and according to the passing cost of the navigation paths, selecting the optimal navigation path and outputting. By the method and the device, successful path calculation can be guaranteed.

Description

technical field [0001] The present application relates to the technical field of navigation, and in particular to a navigation route planning method and device. Background technique [0002] With the construction of roads and the increase of urban vehicle ownership, self-driving travel has become the main mode of transportation. If you do not know the road or cannot find the destination when traveling, the user can perform road navigation through a terminal device (or called a navigation device) equipped with navigation software. When the user uses the navigation device for road navigation, the navigation The device performs navigation route planning (also called road calculation or route calculation) according to the starting position and the destination position, and plans a navigation route for the user, who can drive to the destination according to the navigation route. It can be seen that in the navigation process, calculating the route is a key step. [0003] However...
