Embodiment 1
[0032] Such as figure 1 Shown is an exemplary flowchart of a navigation method in an embodiment of the present invention, and the method includes the following steps:
[0033] Step 101, planning a guiding path from the starting place to the destination according to the starting place and the destination.
[0034] Step 102, determining a current intersection to be guided in the guidance route, an entry road into the current intersection to be guided in the guidance route, and an exit road from the current intersection to be guided in the guidance route.
[0035] Preferably, when it is determined that the distance from the user's current position to the nearest intersection in the guidance route is less than a preset distance, according to the guidance route, determine the intersection closest to the user's current position as the current intersection to be guided.
[0036] It should be noted that the preset distance may be determined according to actual needs, or may be determ...
Embodiment 2
[0101] Based on the same inventive concept as the navigation method provided by the above embodiment, the embodiment of the present invention also provides a navigation device, such as Figure 7 shown, including:
[0102] A planning module 701, configured to plan a guiding path from the origin to the destination according to the origin and the destination;
[0103] An intersection determination module 702, configured to determine a current intersection to be guided in the guidance route, an entry road into the current intersection to be guided and an exit road to the current intersection to be guided in the guidance route;
[0104] The prompt information generation module 703 is configured to generate extended navigation prompt information for the current to-be-guided intersection according to the road attributes of the entry road and the exit road of the current to-be-guided intersection, and the extended navigation prompt information is at least Including one of direction p...

Abstract
The invention discloses a navigation method and device. The method includes: planning a guiding path from the starting point to the destination according to the starting point and the destination; Enter the incoming road at the current intersection to be guided and the exit road that exits the current intersection to be guided; generate extended navigation for the current intersection to be guided according to the road attributes of the incoming road at the current intersection to be guided and the road attributes of the outgoing road Prompt information, the extended navigation prompt information includes at least one of direction prompt information, lane change prompt information and subsequent steering prompt information; the extended navigation prompt information is added to the navigation prompt information and output to the user. The present invention can provide the user with extended navigation prompt information such as direction prompt information, lane change prompt information and subsequent steering prompt information, so as to better assist the user in driving and improve user experience.
Description
technical field [0001] The invention relates to the technical field of intelligent navigation, in particular to a navigation method and device. Background technique [0002] At present, navigation equipment has brought great convenience to people's travel. After the user sets the starting point and the ending point on the navigation device, the navigation device can generate a guiding path (driving route) from the starting point set by the user to the ending point set by the user according to the saved map data, and perform navigation guidance according to the guiding path. [0003] In the prior art, when the user approaches the nearest intersection to be guided in the guidance route, the navigation device determines the user's turn at the intersection according to the angle between the road entering the intersection and the road exiting the intersection in the guidance route Action and broadcast the steering action prompt information to the user through voice. For example...
