Abstract

The present disclosure provides a method and a system for updating an in-vehicle navigation map, an in-vehicle navigation device, and a mobile terminal. The method includes: establishing a connection with a mobile terminal; sending a configuration file of the in-vehicle navigation map to the mobile terminal via the connection, in which the configuration file includes regions and versions of map data corresponding to the regions; receiving latest map data sent by the mobile terminal, and updating the map data of regions corresponding to the latest map data, in which the latest map data is obtained by the mobile terminal according to the configuration file.

First claim

What is claimed is:

1. A method for updating an in-vehicle navigation map, performed by an in-vehicle navigation device, and comprising:
establishing a connection with a mobile terminal, including:
establishing a Wireless Fidelity WiFi hotspot; and
receiving and responding to a request initiated by the mobile terminal for accessing the WiFi hotspot;

sending a configuration file of the in-vehicle navigation map to the mobile terminal via the connection, wherein the configuration file comprises regions and versions of map data corresponding to the regions; and
receiving latest map data sent by the mobile terminal, and updating in the in-vehicle navigation map the map data of regions corresponding to the latest map data, wherein the latest map data is obtained by the mobile terminal according to the configuration file;
wherein establishing a WiFi hotspot comprises:
generating a two-dimensional code containing a Service Set Identifier SSID of the WiFi hotspot, such that the mobile terminal obtains the SSID of the WiFi hotspot by scanning the two-dimensional code;

wherein the two-dimensional code is a machine-readable optical label.

2. The method according to claim 1 , wherein the configuration file of the in-vehicle navigation map is sent to the mobile terminal by SOCKET communication, and the latest map data is sent from the mobile terminal to the in-vehicle navigation device by SOCKET communication.

3. A method for assisting in updating an in-vehicle navigation map, performed by a mobile terminal, and comprising:
establishing a connection with an in-vehicle navigation device including:
scanning for Wireless Fidelity WiFi hotspots to obtain an Access Point AP list, in which the AP list comprises the WiFi hotspot established by the in-vehicle navigation device;
scanning a two-dimensional code generated by the in-vehicle navigation device to obtain a Service Set Identifier SSID of the WiFi hotspot generated by the in-vehicle navigation device, in which the SSID of the WiFi hotspot generated by the in-vehicle navigation device is included in the two-dimensional code; and
accessing the WiFi hotspot established by the in-vehicle navigation device;

receiving a configuration file of the in-vehicle navigation map from the in-vehicle navigation device via the connection, wherein the configuration file comprises regions and versions of map data corresponding to the regions; and
obtaining latest map data according to the configuration file, and sending the latest map data to the in-vehicle navigation device for updating the map data of regions corresponding to the latest map data;
wherein the two-dimensional code is a machine-readable optical label.

4. The method according to claim 3 , wherein accessing the WiFi hotspot established by the in-vehicle navigation device comprises:
accessing the AP matched with the SSID in the AP list.

5. The method according to claim 3 , wherein the latest map data is obtained from a network side via WiFi.

6. The method according to claim 3 , wherein obtaining latest map data according to the configuration file comprises:
obtaining a region list from a map application server, in which the region list comprises regions whose map data is updatable and versions of map data corresponding to the regions in the map application server; and
downloading the latest map data from the map application server according to the region list and the configuration file.

7. The method according to claim 6 , wherein downloading the latest map data according to region list and the configuration file comprises:
comparing the versions in the configuration file with the versions in the region list to obtain regions to be updated, in which the version of a region to be updated in the configuration file is lower than the version of the region to be updated in the region list; and
downloading the latest map data of the regions to be updated from the map application server.

8. An in-vehicle navigation device, comprising:
a processor; and
a memory, configured to store instructions executable by the processor,
wherein, the processor is configured to:
establish a connection with a mobile terminal by:
establishing a Wireless Fidelity WiFi hotspot; and
receiving and responding to a request initiated by the mobile terminal for accessing the WiFi hotspot;

send a configuration file of a in-vehicle navigation map to the mobile terminal via the connection, wherein the configuration file comprises regions and versions of map data corresponding to the regions; and
receive latest map data sent by the mobile terminal, and update in the in-vehicle navigation map the map data of regions corresponding to the latest map data, in which the latest map data is obtained by the mobile terminal according to the configuration file;

wherein establishing a WiFi hotspot comprises:
generating a two-dimensional code containing a Service Set Identifier SSID of the WiFi hotspot, such that the mobile terminal obtains the SSID of the WiFi hotspot by scanning the two-dimensional code;

wherein the two-dimensional code is a machine-readable optical label.

9. The in-vehicle navigation device according to claim 8 , wherein the processor is configured to send the configuration file of the in-vehicle navigation map to the mobile terminal by SOCKET communication, and receive the latest map data sent from the mobile terminal by SOCKET communication.
