Embodiment

[0030] Such as figure 2 As shown, an intelligent vehicle path planning method based on the improved Floyd algorithm realizes the shortest path planning from the initial parking point to the target parking point in the underground parking garage, and all possible equivalent shortest paths can be obtained, and The client pops up a prompt sign at the path turning point; the method specifically includes the following steps:

[0031] (1) if figure 1 As shown, the parking spaces in the parking garage are numbered according to the spatial order, and the number of the parking spaces is used as a shared node, and the weight matrix between the parking spaces is imported, and the weight matrix W is initialized, where the element w[i] [j] represents the weight of node i to node j;

[0032] In this embodiment, the initialization rule for the element w[i][j] of the weight matrix W is: if node i is adjacent to node j, then the weight from node i to node j represented by w[i][j] The value...

Abstract

The invention discloses an intelligent vehicle route planning method based on an improved Floyd algorithm. The method comprises the following steps: firstly, numbering parking spots of parking spacesof a parking garage according to a spatial order, and importing a weight matrix between the parking spaces of the parking garage; then, performing calculation according to the weight matrix and the improved Floyd algorithm to obtain a distance matrix and a route matrix, and storing the route matrix in a local system; after a starting parking space serial number and a target parking space serial number are input, searching the route matrix to obtain all possible shortest routes; and finally, displaying all possible equivalent shortest routes in a client interface one by one. According to the method disclosed by the invention, the shortest route planning from the parking spot of the starting parking space to the parking spot of the target parking space in an underground parking garage is achieved, all possible equivalent shortest routes can be obtained, and a client pops up a prompting sign at a route turning point, thereby having practical reference significance for the route planning of intelligent driving of vehicles.

Description

technical field [0001] The invention relates to the field of path planning, in particular to an intelligent vehicle path planning method based on the improved Floyd algorithm. Background technique [0002] In recent years, under the wave of intelligent development of automobiles, intelligent driving technology has made great progress. Intelligent vehicle path planning refers to planning a feasible path from the initial state to the target state in a modeled environment according to certain evaluation criteria. Existing algorithms have high efficiency in solving the shortest path, but for the case of multiple shortest paths, further research is still needed. The Floyd algorithm has high execution efficiency and a small amount of calculation. After improvement, it can be well applied to the intelligent vehicle autonomous guidance parking path planning system. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings and deficie...
