Description

Technical Field

[0001] The present invention belongs to the technical field of data storage, and in particular, relates to a vehicle navigation data storage method and system. Background Art

[0002] With the development of intelligent vehicle navigation, the requirements for accurate positioning data of navigation are getting higher and higher, and the amount of stored data is gradually increasing, resulting in a large amount of vehicle navigation data storage occupying storage space.

[0003] In the Chinese Public Invention with application number CN202410578821.7, a vehicle navigation data configuration method is disclosed, which includes: obtaining a target use location identifier of a vehicle, wherein the vehicle pre-stores an offline map data packet consisting of offline map data corresponding to a plurality of to-be-used location identifiers, and the offline map data corresponding to different to-be-used location identifiers are stored in different locations; obtaining the offline map data corresponding to the target use location identifier from the offline map data packet as the navigation data of the vehicle. This method can obtain the navigation data to be used by the vehicle by only obtaining the target use location identifier of the vehicle, thereby simplifying the process of obtaining vehicle navigation data, thereby reducing the management cost and certification cost of vehicle production, and improving the user experience.

[0004] The defect of the existing patent is that the storage space of the traditional vehicle navigation system is small. Storing the multiple offline map data in the vehicle increases the amount of data stored in the vehicle storage system, affecting the space for vehicle system safety data or other operating data, and at the same time affecting the efficiency of the storage system. Summary of the invention

[0005] In view of the problem that the increase in the storage amount of existing vehicle navigation data affects the use efficiency of the storage system, the present invention provides a vehicle navigation data storage method and system.

[0006] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0015] Further, the user navigation destination request includes at least user information and navigation destination data;

[0016] User information is used to match and find the corresponding user on the vehicle navigation data storage cloud platform, and is also used to verify whether the user information is legal on the cloud platform;

[0017] The navigation destination data is used as the query field for fuzzy query of the vehicle navigation data storage cloud platform.

[0021] Then, the fuzzy query field data group is input into the database of the vehicle navigation data storage cloud platform, and all relevant navigation data results are obtained by query;

[0022] Finally, according to all relevant navigation data results obtained from the query, the top 5-10 relevant navigation data results with the highest similarity are selected and displayed to the vehicle navigation rendering map user end.

[0023] Furthermore, the method for obtaining the navigation destination data fuzzy query field data group includes:

[0024] The navigation destination data is extracted from the first character, and the number of characters extracted each time is N, and the value range of N is (1<=N<=the entire character string length of the navigation destination data);

[0025] According to the different values ​​of the truncation length N, it is divided into different fuzzy query field data groups;

[0026] The semantic composition rationality of the selected fields in different fuzzy query field data groups is judged, and the unreasonable semantic fuzzy query field data groups are deleted. The premise of judging whether the selected field is reasonable can be determined by entering the field into the dictionary to check whether the phrase exists, and at the same time, the field without the composition word is eliminated to affect the accuracy of all relevant navigation data results.

[0027] Furthermore, the vehicle navigation data storage cloud platform is also provided with a historical navigation data recommendation module and a personal frequently used navigation data storage module;

[0028] The historical navigation data recommendation module is connected to the database of the vehicle navigation data storage cloud platform for verifying the legality of the user information on the cloud platform and obtaining the historical navigation vehicle navigation data of the user on the vehicle navigation rendering map user end in the database;
