AI Technical Summary

Technical Problem

In complex urban traffic environments, autonomous vehicles face the problem of low navigation identification accuracy, especially at complex intersections, it is difficult to accurately identify traffic flow, rules and mixed traffic of pedestrians and non-motor vehicles.

Method used

By obtaining the navigation data of the vehicle terminal and intersection identification request, identifying complex intersections continuously and continuously close to each other in advance, generating lane-level navigation routes, providing detailed intersection information, and planning lane-level paths for autonomous vehicles in advance to avoid missing the best lane-change opportunity.

Benefits of technology

It greatly improves the navigation and intelligent perception, control and decision-making capabilities at continuous crossings, improves navigation accuracy, is adaptable and robust, and can cope with complex changes in different cities and intersections.

Abstract

The embodiment of the invention provides an intersection navigation method, a vehicle terminal, a storage medium and a program product. Relates to the technical field of map navigation. The method comprises the following steps: according to navigation data and an intersection identification request, determining a first intersection which is a first preset distance away from the real-time position of a vehicle terminal in the advancing direction of the vehicle terminal; and determining a second intersection at a second preset distance from the first intersection based on the forward direction and the navigation data. In the navigation data, acquiring first vehicle information of the first intersection and second vehicle information of the second intersection; and determining passing direction consistency information between the first intersection and the second intersection according to the first vehicle information and the second vehicle information. And if the passing direction consistency information represents that the second intersection is a continuous over-close complex intersection, generating a lane-level navigation route between the first intersection and the second intersection. The method is used for achieving the effect of improving the navigation accuracy of the complex intersection.
