Description

Update device and method of navigation

More particularly, the present invention relates to an update apparatus and method for updating navigation data, and more particularly, it is possible to minimize a rollback by setting an optimal save point by setting a save point based on the found route information when updating navigation data The present invention relates to an updating device of a navigation device and a method thereof.

In general, navigation refers to a driving guidance system or a driving guidance system that provides position information to a vehicle in operation and accurately guides the vehicle to a destination.

Navigation uses the data received from the satellite positioning system (GPS) satellite to show the current location and direction of the vehicle on the screen. When visiting the unfamiliar area, And the estimated distance time.

Also, if the vehicle travels in a direction different from the direction indicated by the navigation device during the operation, it re-routes or broadcasts a warning message to help the driver to drive safely.

The navigation device searches the destination using the stored map information. Therefore, the map information should be updated relatively frequently to ensure reliable and optimized route guidance.

In general, in order to update the map information, a user connects to the map providing server through a computer to download the update information, and then connects to the navigation system to update the map information. However, the map information is periodically retrieved and the retrieved update information is downloaded There has been a problem in updating the navigation.

Accordingly, in the case where update information is generated using wireless communication in recent years, the update is automatically downloaded from the navigation system.

BACKGROUND ART [0002] The background art of the present invention is disclosed in Korean Patent Laid-Open Publication No. 2015-0089591 (published on May 5, 2015, Automatic updating device and method for navigation).

When the update information is automatically downloaded and updated using the wireless communication, even if the power is turned on after the start is turned off, the update process is not restored to the off-state but is performed before the start-off by rollback .

Therefore, in order to minimize the rollback phenomenon, the save point is set periodically. When the save point is reached, the updated log data is temporarily stored so that only the save point is rolled back even if the power is turned off. It is possible to update from point to point.

However, if the save point is set a little, there is a lot of data to be rolled back so that the amount of data to be updated increases. However, if the save point is set to a large amount, the amount of data to be rolled back is small. And the update performance is deteriorated.

1, a navigation updating device according to an embodiment of the present invention includes a map data storage 20, a communication unit 50, a temporary storage unit 60, an internal storage unit 70, 40).

The map data storage unit 20 is managed by a DBMS (Data Base Management System) and stores map information for searching a traveling route and guiding the search route.

The communication unit 50 is connected to an update server (not shown) through a network communication network to download update data.

The temporary storage unit 60 temporarily stores the update data for updating from the update data downloaded in the form of a temporary file, and the update data stored at the time of the startup off is deleted.

The internal storage unit 70 stores the update data and the update log information stored in the temporary storage unit 60. When the update data stored at the time of the startup off is held and the startup is again turned on, So that the update data can be continuously stored following the stored update data based on the stored update data, and the update can be performed based on the stored update data.

Here, the update log information may include a set save point.

After setting the save point based on the path information searched to the destination, the control unit 40 downloads the update data from the update server through the communication unit 50, stores the update data in the temporary storage unit 60 for updating, The update data stored in the temporary storage unit 60 can be stored in the internal storage unit 70 when the save point reaches the save point.

The control unit 40 stores all the update data in the internal storage unit 70 and stores the update data stored in the internal storage unit 70 in the map data storage unit 20 when the storage is completed have.

Here, the route information can be searched based on the map information stored in the map data storage unit 20 for the destination inputted through the key input unit 30. [

At this time, the route information may include information on a point where the vehicle can stop, such as a stopover point including a gas station and rest area.

Therefore, the control unit 40 can extract a save point setting point such as a waypoint and a destination from the route information, and calculate a scheduled arrival time on the basis of the current position received from the GPS receiving unit 10 as a save point.

At this time, the control unit 40 sets a save point to a set time, for example, one minute to five minutes before the estimated arrival time, in consideration of the case where the start and stop of the stopover and the destination are turned off. The update data can be stored in the internal storage unit 70 and maintained at the save point set before the arrival.

Meanwhile, the controller 40 determines the update log information stored in the internal storage unit 70 when the startup is on, and if the storage is not completed and the startup is off, the control unit 40 determines the save point, 60). Thereafter, the control unit 40 can initialize the update log information when the update data is stored.

As described above, according to the updating device of the navigation according to the embodiment of the present invention, when updating the navigation data, it is possible to minimize the rollback by setting an optimal save point by setting a save point based on the detected route information In addition, it can improve update performance.

As shown in FIG. 2, in the navigation updating method according to an embodiment of the present invention, when the startup is turned on, the controller 40 determines update log information stored in the internal storage unit 70, It can be determined whether it is in progress (S10).

If it is determined in step S10 that the update is not in progress, the control unit 40 extracts a save point setting point from the path information searched to the destination (S20).

Here, the save point setting point may include a waypoint and a destination on the route information. That is, a point at which the driver can stop the vehicle and turn off the start point can be extracted as the save point setting point. For example, the transit route may include at least one of a gas station and a rest area.

After extracting the save point setting point in step S20, the control unit 40 calculates the estimated arrival time to the save point setting point based on the current position received from the GPS receiving unit 10 (S30).

After calculating the estimated arrival time to the save point setting point in step S30, the control unit 40 sets a save point before the scheduled arrival time (S40).

Here, when setting the save point, the control unit 40 sets the save point to a preset time, for example, one minute to five minutes before the expected arrival time, in consideration of the case where the driver arrives at the save point set point and turns off the start The update data can be stored and stored in the internal storage unit 70 at the save point set before the arrival even if the startup is turned off when it arrives at the waypoint.

After setting the save point in step S40, the control unit 40 stores the update data in the temporary storage unit 60 for updating the update data downloaded from the update server (not shown) (S50).

If it is determined in step S10 that the update is in progress, the control unit 40 may store the update data in the temporary storage unit 60 from the save point that is the rollback point based on the update log information.

Here, the control unit 40 may store the update data in the form of a temporary file, and the temporary storage unit 60 deletes the update data stored in the start-off state.

In step S50, when the update data is stored in the temporary storage unit 60, the control unit 40 determines whether a save point has been reached (S60).

If it is determined in step S60 that the save point has been reached, the controller 40 stores the update data stored in the temporary storage unit 60 in the internal storage unit 70 (S70). At this time, the control unit 40 may store the update log information together with the update data.

Here, the internal storage unit 70 stores the update data stored in the internal storage unit 70 when the startup data stored in the internal storage unit 70 is maintained and the update data is continuously stored in the temporary storage unit 60, and allows the update to proceed based on the stored update data.

However, if it is determined that the save point has not been reached in step S60 and the save point has not been reached, or after the update data is stored in the internal storage unit 70 in step S70, the control unit 40 determines whether the update data has been stored (S80).

In step S90, it is determined whether or not the update data is completely stored. If the storage is not completed, the control unit 40 returns to step S50 and stores the update data continuously.

On the other hand, if it is determined in step S80 that the update data has been stored, the control unit 40 stores the update data stored in the internal storage unit 70 in the map data storage unit 20 for update S90).

Thereafter, the control unit 40 can initialize the update log information after the update.

As described above, according to the update method of navigation according to the embodiment of the present invention, when updating the navigation data, it is possible to minimize the rollback by setting an optimal save point by setting a save point based on the found route information In addition, it can improve update performance.
