Navigation information sharing system and navigation information sharing method

Abstract

The invention provides a navigation information sharing system and a navigation information sharing method. The navigation information sharing system comprises a navigation device, wherein the navigation device comprises a first storage unit, a path acquisition unit and an external electronic device; the first storage unit is used for storing first map information; the path acquisition unit is used for acquiring the first path information of a first path during current traveling in real time; the external electronic device is in communication connection with the navigation device; the external electronic device comprises a second storage unit for storing second map information; when the navigation device judges that the first map information does not contain the first path information, the navigation device transmits the first path information to the external electronic device, and the external electronic device judges whether the second map information contains the first path information; when the external electronic device judges that the second map information contains the first path information, the external electronic device shares the second map information to the navigation device. According to the navigation information sharing system and the navigation information sharing method which are disclosed by the invention, the private map information can be established and managed more conveniently by a user, and is selectively shared with the navigation device which is in communication connection with the navigation information sharing system for use.

Description

technical field [0001] The present invention relates to a navigation information technology, in particular to a navigation information sharing system and method that utilizes an external electronic device to provide private map information for comparison and sharing to a navigation device. Background technique [0002] At present, the car navigation devices (Personal Navigation Device) on the market all have built-in map information for drivers to use. However, the actual road information will continue to change with urban construction and various conditions, so users must Rely on companies that sell navigation devices (services) to regularly update the map information in the navigation device to obtain more accurate and updated map information. [0003] However, not all road area information is fully included in the update files of the navigation device (service) company, and even map information about private land, which the landowner does not wish to disclose to the publi...

AI Technical Summary

Problems solved by technology

[0004] In the current scheme, the map information in the electronic device can be shared with the navigation device anytime and anywhere by using the electronic device with map editing function carried around, so that the driver can obtain more map information. It solves the problem of lack of information in the above-mentioned navigation device, but in practical applications, this map sharing method is often one-way, and it further depends on the accuracy of the map information in the electronic device, and cannot realize the navigation device and the electronic device. Real-time interconnection updates between devices when special road conditions are encountered during actual driving
