Embodiment Construction

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] The currently predicted best reference track route of the vehicle has the problem of low accuracy, which leads to a low reference value of the best reference track route of the vehicle. Based on this, the implementation of the present invention provides a construction method, device and electronic equipment for the best reference track route, which can effectively improve the accuracy o...

Abstract

The invention provides a method, device and electronic equipment for constructing an optimal reference track route, and relates to the field of vehicle assisted driving. The method includes: obtaining the current driving road and driving direction of the target vehicle; Each branch road and the road information of each branch road; calculate the road weight corresponding to each branch road according to the road information of each branch road and the statistical information of historical driving roads, and determine the branch road with the largest road weight as the target The reference sub-roads of the vehicle; construct the best reference track route based on all the reference sub-roads of the target vehicle. The present invention can effectively improve the accuracy of the predicted best reference track route, and further help to improve the reference value of the best reference track route, and improve the credibility of the generated best reference track route.

Description

technical field [0001] The invention relates to the technical field of driving assistance, in particular to a method, device and electronic equipment for constructing an optimal reference track route. Background technique [0002] An electronic map is a map that uses computer technology and is stored and consulted digitally. With the continuous development of electronic maps, electronic maps can provide users with more services, such as using electronic maps to provide users with driving assistance services, or forecasting The distance traveled by the vehicle in the future. Among them, the electronic horizon is an abstract subset of the electronic map, which is composed of all possible routes in front of the vehicle. The best reference track route is the main route of the electronic horizon. The best reference track route predicted currently exists. The problem of low accuracy, the reference value of the best reference track route of the vehicle is low. Contents of the in...
