Navigation prompt method, navigation device and storage medium

Abstract

The invention discloses a navigation prompting method. The navigation prompting method comprises following steps: a guiding path, positioning data, and map data in a preset range of the positioning data are obtained; path lane coupling is carried out based on the guiding path and the positioning data; if path lane coupling is failed, map lane coupling is carried out based on the map data and the positioning data; if the path lane coupling or the map lane coupling is success, the current coupling lane is recorded, and promoting is triggered. According to the navigation promoting method, if onecoupling selected from the path lane coupling and the map lane coupling is success, navigation promotion taking the lane as a promoting unit is obtained, so that more accurate navigation promotion isrealized.

Description

technical field [0001] The present application relates to the field of navigation, in particular to a navigation prompt method, a navigation device and a storage medium. Background technique [0002] In the existing navigation software, the smallest unit of the guidance path of the guidance prompt module is the road, and the lane is only one of the attributes, which only includes a simple arrangement and guidance description, and there is no corresponding geographic location information and detailed attribute information such as variable lanes. . In the process of driving, it is often possible to change the position according to the attributes of the lane. For example, when the vehicle is in the straight lane at the intersection, the navigation software may prompt to turn left, but according to the traffic rules, the solid line lane at the intersection is not allowed to change lanes, which may easily cause the user to violate the traffic rules.
