Problems solved by technology

However, due to the rapid development of road construction, especially the increasing renewal of urban roads, it has become impractical to frequently take vehicle-mounted terminals to manufacturers or agency points for map upgrades and cannot meet people's needs.
Therefore it is necessary to provide a new method for upgrading car navigator maps, which aims to overcome the disadvantage that existing car navigator maps can only be updated offline

Embodiment 1

[0028] Such as figure 1 As shown, Embodiment 1 of the present invention includes steps: 1. The vehicle navigator (101) accesses the service platform (102); 2. The service platform (102) updates the latest map version according to the hardware information and software specifications of the vehicle navigator (101) The information is sent to the car navigator (101); 3. The car navigator (101) compares the latest map version with the current map version, and when it is found that the latest map version is higher than the current map version, download the latest version of the map from the service platform (102) to perform upgrade.

Embodiment 2

[0030] Such as figure 1 As shown, Embodiment 2 of the present invention includes steps: 1. The car navigator (101) accesses the service platform (102), and the service platform (102) determines the current city information of the car navigator (101); 2. The service platform (102) According to the hardware information of the car navigator (101), the software specification sends the latest map version information of the current city to the car navigator (101); 3. The car navigator (101) compares the latest map version with the current map version and finds that When the latest map version is higher than the current map version, the compressed latest version map fragment is downloaded from the service platform (102) for upgrading.

Abstract

The invention in particular relates to a method for supporting a vehicle navigator to update a map on line. The method comprises the processes that 1. the vehicle navigator is connected to a service platform via a mobile communication network by utilizing a data communication module; 2. the service platform obtains the latest map version information according to the hardware information and software specification of the vehicle navigator and the vehicle navigator receives the map version information and compares the received map version information with the current map version information; 3. when the map version information received by the vehicle navigator is higher than the current map version information, the latest version of map is downloaded from the service platform to update the current map; the vehicle navigator integrates the data communication module and the data communication module is responsible for connection with the internet. The problem that the vehicle navigator can not update the map on line is solved by utilizing a mature mobile network. The method has the advantages of convenience, practicability and economy.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for realizing online map updating of a car navigator. Background technique [0002] Car navigator is a driving auxiliary device that can help users accurately locate the current location, calculate the itinerary according to the predetermined destination, and guide the user to the destination through map display and voice prompts. [0003] With the development of social economy, the scale of the automobile market is getting bigger and bigger, and the number of users who own cars is also increasing. With the maturity of satellite navigation technology, satellite navigation systems such as car navigator GPS and Beidou can quickly locate the current location coordinates of the car, thereby promoting the gradual popularization of car navigators. The principle of GPS technology is that the car navigator sends a request for location information to the satellite through...
