Description

System and method for partial updating of map data}

The present invention relates to a navigation, and more particularly, a partial update method of map data for partially updating map data by searching for multiple routes in the latest map data of a server and selectively receiving a newest or optimal route in the navigation, and the same. A system for

Recently, technologies for improving road efficiency are provided by minimizing driving and time costs by providing real-time section traffic information to road users, and by distributing vehicles as much as possible by preventing traffic concentration on limited roads. In the case of navigation using such traffic information, there is a need to update the internal map for various reasons such as the creation or deletion of a new road.

Conventionally, the operator has managed the change history by manually modifying changes to existing map data and manually recording them.

Users then access the website, download new map data, and use it to update their navigation.

However, there is an inefficient structure for updating unaltered data that does not require updating when updating a map of a navigation service that is conventionally serviced. In other words, updating all the data at once increases the burden on the terminal for the update and causes inconvenience to customers by using the website.

In other words, the navigation system does not always maintain the latest map data, and in order to receive route guidance by adding new roads, the user can update the entire map data or search for a single route in the existing navigation system to check whether there is an update for the surrounding route. Partially update the map data of the system.

At this time, the existing navigation may have a route that cannot be searched in the map data, which has a disadvantage of not guiding an optimal route to the user.

Therefore, in order to solve the above problems, the present invention searches for and receives at least one or more paths from the latest map data of the server, and selects the latest or optimal path, thereby substituting the difference data to the navigation map data. Its purpose is to provide a way to update.

Partial update method of the map data according to the present invention for achieving the above object comprises the steps of: receiving location information from the user and transmitting to the server; The server searching for at least one path corresponding to the location information received from the navigation; The navigation may further include a third step of receiving at least one or more paths searched by the server, and selecting one of the at least one or more paths from a user; Transmitting the selected route and map data version to the server; A fifth step of the server comparing the route received from the navigation with the version of the map data, and transmitting the changed map data to the navigation; And a sixth step of receiving the changed map data from the server, partially updating the corresponding map leaf, and guiding a route.

In addition, the navigation according to the present invention includes a receiving unit for receiving location information from the GPS; A wireless unit for transmitting and receiving to and from a server; A key input unit for receiving a starting point, a destination, or a waypoint from the user; A storage unit for storing map data; A controller which compares the map data received from the server with the map data stored in the storage unit, expresses at least one route received from the server, requests the server to select the route selected by the user, and partially updates the map data; ; And a display unit for displaying the map data under the control of the controller.

The partial update method and system therefor according to the present invention search for and receive at least one or more paths from the latest map data of the server, and select the desired path among the at least one or more paths to partially select the difference data. The update reduces the cost of updating the map data and gives the user various options for partial updates.

In addition, if the server receives the same path in the future, if the update is already completed, there is no need to update the map data again, thereby reducing the burden of communication costs.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to an update between a server (not shown) and a navigation, and will be described with reference to the navigation.

The present invention receives at least one route from the at least one navigation to search for at least one route, transmit the at least one route to the navigation, and then receive the selected route and map version from the navigation to receive A server for comparing the map version with a map version stored in the server and transmitting map data corresponding to the map version stored in the server to the navigation device when there is a change in the map version;

Send a destination or present location to the server and select any path among at least one or more paths searched and received from the server to transmit the selected route and map version to the server again, and receive the corresponding map data from the server. It consists of a system for partial update of map data including navigation for updating.

1 is a block diagram of a navigation according to the present invention.

Referring to FIG. 1, a receiver (not shown) receives location information from a GPS.

The wireless unit 100 transmits and receives with a server.

The key input unit 110 includes a plurality of function keys as a user interface and receives a starting point, a destination, or a waypoint from the user.

The storage unit 120 stores a predetermined program for controlling the overall operation of the navigation and various data input / output when the control operation of the navigation is performed.

Preferably, the storage unit 120 stores the map data.

Even more preferably, the storage unit 120 stores the latest map data received from the server. Accordingly, the map data is stored in two pieces of pre-stored map data and map data received from the server. When the map data is updated with the latest map data, the existing map data is deleted.

The sound output unit 130 includes a speaker provided in the navigation, and outputs the sound signal stored in the storage unit 120 in an audible state under the control of the controller 150.

The display unit 140 displays the map data under the control of the controller.

The controller 150 compares the map data received from the server with the map data stored in the storage unit, checks whether there is an update, displays the multiple paths received from the server, requests the server selected from the user, and requests the corresponding path. Partially update the map data.

Preferably, the information on at least one path of the server includes at least one of a link, a node, or a mesh unit.

In addition, the controller 150 performs partial update by comparing the found route or link list from the server in units of objects.

In addition, the controller 150 extracts the corresponding leaflet list from the link list and compares the leaflet list.

Preferably, the server transmits detailed information when transmitting multiple paths.

More preferably, the details include any one or more of cost, time, POI information when using the multi-path.

In other words, the travel cost and time can be calculated for each route, and POI information such as restaurants and gas stations is included during the movement.

In addition, the controller 150 omits the update if the path input through the key input unit 110 is input again later.

In other words, since the update is completed by downloading from the server, the partial update is not performed for the same point.

2 is a flowchart illustrating a method of partially updating map data according to the present invention.

2, the location information is received from the user and transmitted to the server (S200). Preferably, the location information includes any one or more of the vehicle's location, origin, destination or waypoint.

The server searches for at least one path corresponding to the location information received from the navigation (S210).

The navigation device receives at least one or more paths found in the server, and receives a random path among the at least one or more paths from the user (S220). Preferably, the at least one route is a multiple route that can travel from the origin entered by the user to the destination.

Then, the selected route and map data version is transmitted to the server (S230).

Preferably, the at least one path information of the server includes at least one of a link, a node, or a mesh unit.

In addition, the method of checking and updating the presence or absence of the update may partially update the object units based on the searched path or the link list from the server.

In addition, the leaflet list is extracted from the link list and compared with the leaflet unit.

Meanwhile, the server compares the route received from the navigation and the map data version, and transmits the changed map data to the navigation (S240).

In this case, the server transmits detailed information when transmitting at least one path, and includes at least one of cost, time, and POI information when using the at least one path. In other words, since there are at least one route, if you use any route, the cost from the starting point to the destination costs 10,000 won, takes about one hour, and details of the POI such as restaurants, gas stations, hospitals, etc. When transmitting, the user can check the details and select a more desired path.

Preferably, the cost is at least one of a cost of arrival time or a fuel cost to the destination.

Even more preferably, the arrival time cost is calculated by converting the estimated driving time of the vehicle into an amount in consideration of traffic conditions of the destination. The traffic situation of the destination is received by reflecting the TPEG information from the server.

For example, it is calculated on the assumption that it takes 500 won for one minute to move at 30km per hour. Converting the travel time of the vehicle to the amount of money reflects the average value of gas station oil.

Then, the map data is received from the server, the corresponding map leaf is partially updated (S250), and the route is guided (S260).

In addition, if the path input in step S200 is input again by the user later, the update is omitted. In other words, if the same route is downloaded from the server later, if the map is already updated, the map data is guided without updating.

This is to prevent the one-time download of the latest map data from the server in real time, and can reduce the communication cost and effectively cope with the case of communication failure.

That is, even if the map data is stored in the storage unit of the navigation rather than one-time communication can receive the route guidance.

In addition, after comparing the map data version received from the navigation in the server with the map data version existing in the server, and if the map data version of the server is a higher version, update the portion of the route search request in the navigation to the navigation; The first method of transmitting and comparing the map data version of the server and the map data version of the navigation in the navigation, and if the map data version of the server is a higher version, requesting that only the parts required by the navigation can be updated. There is a second way.

Therefore, the present invention uses one or more of the first method of transmitting updated map data from the server to the navigation and a second method of requesting map data to partially update from the navigation to the server.

3 is a diagram illustrating an embodiment of a method of partially updating map data according to the present invention.

Referring to FIG. 3, when at least one route is received from a server, the navigation compares the map data of the server with the map data and the version of the navigation and determines that the map data of the server is the latest map data. Receive a route and receive an arbitrary route from the user. Then, by requesting a selected route from the user, the map data for the corresponding map leaf is partially updated. Assume that there are three routes A, B, and C as shown in FIG. 3. Each route includes at least one of detailed information, namely, cost, time, and POI information when using a route from a starting point to a destination input by a user. In detail, the A route costs 10,000 won to the destination, takes about 40 minutes, and has a new Korean chicken POI. Similarly, if you use route B, it costs 5,000 won to your destination, the distance is about 30 minutes, and if you have a new POI for our hospital, if you use route C, it costs 20,000 won to your destination and the distance is about One hour, and Seoul Mart expresses a new POI.

Accordingly, the user selects a desired route while viewing the details and updates map data only for the selected map with respect to the selected route.

As a result, communication costs are reduced because only partial updates, not full updates, and users can select a desired path for at least one or more paths, thereby providing various options to the user.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.
