Embodiment 1

[0043] Please refer to figure 1 , which is a structural schematic diagram of the navigation system of the present invention, such as figure 1 As shown, the navigation system includes: a navigation device 10 and a cloud server 11 communicating with the navigation device 10. All navigation routes from the current position to the destination are fed back to the navigation device 10 , and data navigation is performed according to the navigation route selected by the user on the navigation device 10 . Wherein, the user's current location (ie geographic location) information includes: latitude and longitude, altitude and direction angle of the user's location.

[0044] Further, the cloud server includes: a real-time road condition device, a statistical data device, a navigation computing device and a data exchange system.

[0045] Wherein, the real-time road condition device is used to obtain the speed information of the user's driving road, which is convenient for the user to avo...

Embodiment 2

[0057] This application also provides a navigation method based on the navigation system in Embodiment 1. For details, please refer to figure 2 The flow chart shown is understood.

[0058] The navigation method shown includes the following steps:

[0059] First, step S1 is executed, and the navigation device is used to obtain the user's current location information and destination address information and upload them to the cloud server;

[0060] Next, step S2 is executed, using the cloud server to calculate all navigation paths from the current position to the destination and feed them back to the navigation device;

[0061] Next, step S3 is executed, and the user selects a navigation path on the navigation device according to the requirement;

[0062] Next, step S4 is executed to perform data navigation according to the navigation path selected by the user.

[0063] Please refer to image 3 , which is a flowchart of a method for acquiring destination address information....

Abstract

The invention provides a navigation system and a navigation method. The navigation system comprises a navigation device and a cloud server, and the cloud server calculates all navigation paths from the current position to a destination according to current user position information and destination address information which are acquired by the navigation device, feeds the navigation paths back to the navigation device and performs data navigation according to the navigation path selected by a user on the navigation device. Accordingly, the navigation device does not need to download navigation data and store the navigation data in local navigation equipment and does not need to participate in large-scale search and calculation of the navigation paths and the like, the work is completed by the cloud server, therefore, the requirement of the navigation equipment for the storage space is reduced, and the cost of the navigation device is lowered; in addition, due to the fact that the work of calculating the navigation paths is also completed by the cloud server, sources of the navigation data can be updated according to the road condition, therefore, navigation updating can be responded more timely, and the reliability of the navigation data is improved.

Description

technical field [0001] The invention relates to the technical field of navigation and communication, in particular to a navigation system and a navigation method. Background technique [0002] With the construction of roads and the increase in the number of urban vehicles, self-driving travel has become a way of travel. If you can’t find your destination or don’t know the road conditions when you travel, users can navigate through navigation devices so that reach the destination. [0003] In the existing technical solution, the navigation device can provide navigation for the user in a local navigation mode, specifically: the navigation device downloads all navigation data to the local for storage, and when providing navigation for the user, plans a route according to the locally stored navigation data, And obtain the geometric data and attribute data of each road section of the navigation path from the navigation data stored locally, and provide navigation services for the...
