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 comprises the steps that according to a starting place and a destination, a guiding path from the starting place and the destination is planned; a current to-be-guided intersection in the guiding path, a pull-in road into the current to-be-guided intersection in the guiding path and a pull-out road out of the current to-be-guided intersection in the guiding path are determined; according to road attributes of the pull-in road of the current to-be-guided intersection and road attributes of the pull-out road, expansion navigation prompting information of the current to-be-guided intersection is generated, wherein the expansion navigation prompting information at least includes one of heading prompting information, lane changing prompting information and following steering prompting information; the expansion navigation prompting information is added into navigation prompting information to be output to a user. The expansion navigation prompting information such as the heading prompting information, the lane changing prompting information and the following steering prompting information can be provided for a user, so that driving of the user is better assisted, and the user experience is improved.

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...
