The terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms and the inventor may appropriately define the concept of the term in order to best describe its invention It should be construed as meaning and concept consistent with the technical idea of the present invention.

Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

Hereinafter, preferred embodiments of the present invention will be described in detail.

FIG. 2 is a block diagram illustrating a navigation system according to a first embodiment of the present invention, and FIG. 3 is a block diagram illustrating a navigation system according to a second embodiment of the present invention. As shown in FIGS. 2 and 3, the navigation device 100 can perform an update in connection with the update server 200 shown in FIG. 2. The user authentication / version management server 200 shown in FIG. And the download server 300 to perform the update.

That is, FIG. 2 is a block diagram illustrating an example of a system for updating a map data storage unit 230, which is a single server, as a user authentication / version management unit 210, a data download unit 220 for providing update data for updating, FIG. 3 is a block diagram illustrating a module for performing a user authentication / version management for updating and a download for storing map data, according to an embodiment of the present invention. And a download server 300 including a user authentication / version management server 200 for performing user authentication / version management and a map data storage unit 310.

On the other hand, the navigation system 100 shown in Figs. 2 and 3 has the same configuration. The navigation system 100 shown in FIG. 2 and FIG. 3 includes a controller 110 for controlling each configuration of the navigation system 100 and a user authentication / version management unit 210 of the update server 200 The communication unit 120 for transmitting the user authentication / version information of the navigation system 100 and receiving the update data from the data download unit 220 of the update server 200, the map data stored in the storage unit, An update unit 130 for storing the received update data in the storage unit and updating the map data, and storage units 150 and 160 for storing the map data.

The control unit 110 is connected to the driving unit 140 and performs position guidance such as route guidance using the map data output from the map matching unit and controls the updating unit 130 to update the navigation unit 100 . Also, it is possible to transmit the user authentication information and the version information of the map data to the update server 200 through the communication unit 120 to request update of the map data of the navigation system 100.

While the reader module 142 of the driving unit 140 performs switching through the first storage unit 150 and the second storage unit 160, the controller 110 controls the driving unit 140 Map-matching the partial map data stored in the memory module 141 to perform location guidance and the like.

The update unit 130 updates the update data received from the update server 200 through the communication unit 120 to either the first storage unit 150 or the second storage unit 160, And switches the connection of the first storage unit 150 and the driving unit 140 of the second storage unit 160.

That is, the navigation system 100 performs the position guidance using the storage unit in which the version of the map data stored in the first storage unit 150 and the second storage unit 160 stores the map data of the latest version, If the version of each map data is the same, the location guidance is performed using any one of the storage units.

At this time, another storage unit not used for location guidance can update the map data through the update unit 130. After the update is completed, the storage unit used for position guidance and the switching unit To change the connection of the driving unit 140.

Accordingly, the storage unit, which has been updated and stores the latest map data, starts to open with the drive unit 140 and closes the connection between the storage unit and the drive unit 140, which have been used previously.

In the switching of the first storage unit 150 and the second storage unit 160, the update unit 130 may update the position guidance or the like through map matching during the time during which the navigation unit 100 performs switching. So that the memory module 141 of the driving unit 140 can store the partial map data for continuous execution.

At this time, the partial map data stored in the memory module 141 of the driving unit 140 is a predetermined radius up to a distance at which the vehicle is moved at the average speed during the switching time, .

The unit map data corresponds to each piece of individual map data among the whole map data, and may be formed by dividing into map areas or administrative areas. For example, when the unit map data is formed as a map, the map data having a predetermined size are combined to form the entire map data.

At this time, the partial map data extracts the map leafs included in a predetermined radius and combines them into partial map data, so that the memory module 141 of the driving unit 140 can store the collected partial map data. While the reader module 142 of the driving unit 140 switches the first storage unit 150 and the second storage unit 160 respectively, the controller 110 controls the partial map stored in the memory module 141, It is possible to perform position guidance through map matching using data.

The driving unit 140 includes a memory module 141 and a reader module 142. The driving unit 140 reads a map stored in the first storage unit 150 or the second storage unit 160 through the reader module 142 And loads the map data necessary for position guidance or the like by accessing the data. The loaded map data is map-matched and used for position guidance or the like through the control unit 110. [

The reader module 142 may access the map data by being connected to either the first storage unit 150 or the second storage unit 160. The first storage unit 150 or the second storage unit 160 And 160, the map data is supplied to the other storage unit through the updater unit 130 to update the map data.

Switching to be connected to the reader module 142 is performed when the reader module 142 is connected to the first storage unit 150 or the second storage unit 160, It means that the connection of the storage unit connected to the reader module 142 is canceled and the connection to the storage unit in which the update is completed is started.

During the switching, the navigation unit 100 may not use the map data stored in the storage unit. During the switching time, the necessary partial map data may be stored in the memory module 141 . The reader module 142 of the driving unit 140 performs a switching operation using the partial map data stored in the memory module 141 during a time period during which switching is performed, After the switching is completed, the navigation unit accesses the storage unit in which the update is completed and loads the map data so that the navigation of the navigation unit 100 can be continuously performed.

Meanwhile, when switching is completed, the driver 140 may reset the memory module 141 and access the map data through the updated storage unit.

The storage units 150 and 160 may include a first storage unit 150 and a second storage unit 160. The storage units 150 and 160 may store the same map data or map data having different versions .

If update is performed on the second storage unit 160 during the navigation of the navigation system 100 using the first storage unit 150, the update unit 160 may be connected to the reader module 142 of the drive unit 140 Switching is performed by closing the connection of the first storage unit 150 and opening the connection of the second storage unit 160 that has been updated.

At this time, the map data of the old version is stored in the first storage unit 150, and the map data of the new version is stored in the second storage unit 160. Accordingly, in one embodiment, the first storage unit 150 can be updated through the update server 200. In another embodiment, the first storage unit 150 does not update the new version map data , The update can be performed using the map data after the new version.

That is, after updating and switching are performed through the storage unit of either the first storage unit 150 or the second storage unit 160, the other storage unit is also updated with the same version of map data Or update the other storage via updated map data after the new version, while maintaining different map versions.

Accordingly, updating of the first storage unit 150 and the second storage unit 160 may be performed according to a map data version management procedure.

4 is a flowchart illustrating an operation method of navigation according to the present invention. 4, the navigation device 100 transmits the user authentication information and the version information to the update server 200 under the control of the controller 110 (S105).

The version information is version information of the map data of the latest version among the map data stored in the first storage unit 150 and the second storage unit 160 of the navigation system 100 and the update server 200 stores the version information of the map data stored in the navigation system 100 If the latest version of the map data is present than the version of the map data, the update data for updating the map data is transmitted to the navigation device 100.

The navigation system 100 determines whether there is a latest version of update data capable of updating map data from the update server 200 (S110).

In step S110, the determination of the update data is made according to the update data transmission signal transmitted from the update server 200. The update unit 130 of the navigation device 100 receives the update data through the communication unit 120, In the storage unit 150 or the second storage unit 160 that is not connected to the reader module 142 of the driving unit 140 and updates the map data of the storage unit in step S115.

The storage unit of the navigation system 100 includes a first storage unit 150 and a second storage unit 160. One of the storage units is opened to the reader module 142 of the drive unit 140 And the other storage unit is disconnected from the reader module 142 of the driving unit 140 and used as a storage unit for updating.

The update unit 130 calculates a distance that can be moved during switching between the first storage unit 150 and the second storage unit 150 according to the average speed of the vehicle, (S120). ≪ / RTI >

The average speed is an average speed of a predetermined driving distance traveled to a position of the vehicle at the time of calculating the average speed or an average speed during a predetermined driving time when the vehicle travels until a time at which the average speed is calculated, And travels at an average speed and is movable for a predetermined time.

Accordingly, the update unit 130 loads the partial map data within the calculated radius within the predetermined radius from the storage unit in which the reader module 142 of the driving unit 130 is opened, (Step S125).

That is, during the time when switching between the first storage unit 150 and the second storage unit 160 is performed, the navigation unit 100 may store the map stored in the first storage unit 150 and the second storage unit 160 Since the access of the data is not allowed, the partial map data of the predetermined radius in which the vehicle can be moved is stored in the memory module 141 so that it can be used for the position guidance of the navigation system 100.

When the partial map data is stored in the memory module 141, the control unit 110 of the navigation unit 100 receives the map data necessary for position guidance from the memory module 141 of the driving unit 140, And outputs the information to the screen to perform position guidance and the like (S130).

That is, before the update is performed, the position guidance of the navigation system 100 is performed by accessing the map data stored in the first storage unit 150 or the second storage unit 160. However, after the update is completed, The partial map data is loaded on the memory module 141 while the switching of the first storage unit 150 and the second storage unit 160 is performed and position guidance is performed using the second map data stored in the memory module 141.

The driving unit 140 closes the connection of the storage unit connected to the reader module 142 of the first storage unit 150 or the second storage unit 160, The storage unit 160 starts opening the storage unit and the reader module 142 (S135).

That is, the navigation system 100 cancels the connection with the storage unit that was previously used to use the map data of the storage unit that has been updated to use the latest map data, and initiates the connection with the storage unit that has been updated, The latestness of the map data can be ensured.

The driving unit 140 determines the point of time when the switching of the first storage unit 150 and the second storage unit 160 is completed and the position guidance is performed through the map data stored in the memory module 141, The necessary map data after the point in time is switched to use the map data of the storage unit in which the open connection with the reader module 142 is started and the partial map data stored in the memory module 141 is reset (S140) .

That is, when the navigation unit 100 completes the connection of the storage unit updated with the new version of the map data to the reader module 142 of the driving unit 140, the navigation unit 100 stops using the partial map data stored in the memory module 141, Performs location guidance using the map data of the connected storage unit, and resets (deletes) the partial map data of the unused memory module 141.

5 is an exemplary diagram for updating navigation during route guidance according to the present invention. As shown in FIG. 5, the position guidance of the navigation includes a route guidance through a route search, and shows an embodiment in which the update is performed during the route guidance.

When the vehicle starts from Seoul City Hall and the route using the Gyeongbu Expressway is set to navigation, navigation can perform the route guidance using the map of A2, B2, C2, C3, D3, E3, F3 and F4.

B2, C2, C3, D3, E3, F3, and F4 located on the searched path when the update of the map data is completed at the location of 'Hannam-dong' The map data to be output after the current position (Hannam-dong) of the driver 140 is loaded on the memory module 141 of the driver 140.

At this time, the map data to be loaded is not the map data of all the paths but the vehicle moves on the route while switching between the storage unit in which the connection is started to the reader module 142 of the driving unit 140 and the storage unit in which the updating is completed Map data up to a possible estimated path is stored. In FIG. 5, the position where the vehicle is positioned at the end of the update is before the 'Seocho IC', and the update unit 130 updates the map data (map data) And the memory module 141 can be stored.

Accordingly, the memory module 141 extracts and stores C2, C3, D3, and E3 including 'Hannam-dong', which is the update start point, to the 'Seocho IC', which is the end point of the update.

Thereafter, when the switching is completed, the reader module 142 initiates the connection of the update storage unit, and the map data of F3 and F4 can continuously perform the route guidance using the map data of the storage unit that has been updated.

That is, the map data including the map of A2 and B2 is used from the storage unit connected to the reader module 142 in advance, and the map data including the map of C2, C3, D3 and E3 during the update (switching) The map data extracted from the storage unit connected to the existing reader module 142 and stored in the memory module 141 is used and the map data including the map of F3 and F4 after completion of the updating (switching) The map data of the storage unit in which the connection with the module is started is used.

6 is an exemplary diagram for updating map data during navigation according to the present invention. As shown in Fig. 6, since the destination is not selected, navigation of the position guidance only outputs the current position of the vehicle on the map data, and accordingly, the traveling direction of the vehicle can not be predicted. Accordingly, FIG. 6 shows an embodiment in which updating is performed in the middle of the position guidance as described above.

When the update of the map data is completed while the vehicle passes the 'Banpo Bridge', the update unit 130 calculates the average speed of the time or distance traveled from the predetermined time or predetermined distance to the current time or current position, Calculates the movable distance during the time when the switching is performed through the average speed, and calculates the update end expected radius.

In this case, the map data included in the calculated expected radius is the leaflets B1, B2, B3, C1, C2, C3, D1, D2, D3, E1, E2, E3 within the radius, So that the memory module 141 of the driving unit 140 can store the map data.

At this time, the map data to be loaded does not include all the map data of the storage unit, but the vehicle is moved on the route while switching between the storage unit in which the connection is started to the reader module 142 of the driving unit 140 and the storage unit, Map data up to a possible estimated distance is stored. In FIG. 6, the update unit 130 extracts the map data (map leaf) included in the expected radius, including the map data (map leaf) at the update start point, So that the memory module 141 can store it.

B1, B2, B3, C1, C2, C3, D1, D2, D3, E1 included in the radius from the position of the 'Banpo Bridge' , E2, and E3 are extracted and stored.

Thereafter, when the switching is completed, the reader module 142 initiates the connection of the storage unit that has been updated. Accordingly, the map data after the position where the vehicle has been moved during the switching process is guided by using the map data of the storage unit, It can be done continuously.

A map including B1, B2, B3, C1, C2, C3, D1, D2, D3, E1, E2, and E3 maps within a predetermined radius from the current position during the update process, Data is extracted from the storage unit connected to the existing reader module 142 and used in the map data stored in the memory module 141. After the update (switching) is completed, the map is stored in the storage unit Data is used.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, Various changes and modifications will be possible.
