The network 100 may be implemented in various ways. For example, a network related to embodiments of the present invention may include a social network.

Hereinafter, a social network related to one embodiment of the present invention will be described.

3 is a conceptual diagram illustrating a social network related to one embodiment of the present invention.

Social network is one of the fields of web science research, and refers to a structure of social relations in which an individual or a group becomes a node on the web and is formed by interdependent relationships between the nodes. At this point, all nodes are individual entities within the network, and a tie is the relationship between each node (the source is Wikipedia).

The social network according to the present invention has one or more second nodes B, C, D, E, F, having a relationship with the first node A, centering on the first node A. G, H, I).

The first and second nodes A, B, C, D, E, F, G, H, and I may be a specific location, a specific road, a specific building, a specific user, a specific terminal, or the like.

For example, when the first node A is a specific user, other users or terminals having a relationship with the user may configure the social network 100 together with the specific user as a second node.

When the first node A is a specific road, other roads, buildings, terminals or users having a relationship with the specific road may constitute the social network 100 together with the specific road as a second node. .

When the first node A is a specific building, other buildings, roads, terminals or users having a relationship with the specific building may constitute the social network 100 together with the specific building as a second node. .

When the first node A is a specific location, other locations, roads, buildings, terminals, or users having a relationship with the specific location may constitute the social network 100 together with the specific location. Can be.

Since the social network 100 according to the present invention is formed around a specific node, various social networks 100 may be configured according to a specific node. For example, when the specific node is 'Southbound Ring Road', 'Star Tower', 'Gangnam Station', 'Yeouido', etc., the information networks 500 formed around the specific nodes may be different. In this case, the information networks 500 may not coincide with each other, but some of the other nodes included in one information network 100 may be included in the other information network 100. For example, assuming that the user A and the user B are included in the network 100 formed around the node called 'Southbound circulation road', the user A is located in the network 100 formed around the node called 'star tower'. And User C may be included. In other words, the user A node may be included in both the network formed around the southern circulation road and the network formed around the star tower.

At this time, the nodes (A, B, C, D, E, F, G, H, I), preferably, may have a position attribute corresponding thereto. For example, when the nodes are a specific location, a specific road specific building, etc., the location of the specific location, specific road, specific building, etc. may be a location attribute corresponding to the node, and the nodes are specific users or specific terminals. In this case, the current location of the specific terminal or the specific user may be a location attribute corresponding to the node.

In addition, the first node A may be classified into a static node and a dynamic node. The static node refers to a node whose location property corresponding to the specific location, a specific road, a specific building, and the like is not changed. The node refers to a node whose location property corresponding to the specific user or the specific electronic device may change over time.

In addition, although the first node A and the second nodes B, C, D, E, F, G, H, and I all have a relationship, B, C, E, F, G, I Nodes are directly related to the first node A, but D and H nodes are indirectly related to the first node B (the line connecting the node and the node in the drawing is connected to the node). They have a direct relationship). For example, node D has a relationship with the first node A through node I or node G, and node H has a relationship with the first node A through node B or node F. have.

In this case, the B, C, E, F, G, I nodes are defined as having a primary relationship with the first node (A), the D, H nodes are secondary to the first node (A) Let's define that we have a relationship. Of course, although not shown in the figure, if there is no relationship with any of the B, C, E, F, G, I, but has a relationship with any one of the D, H nodes, such a node It may be defined that it has a tertiary relationship with the first node (A).

Meanwhile, according to an embodiment of the present invention, the relationship between the first node A and the second nodes B, C, D, E, F, G, H, and I may be kept static. According to the positional relationship between the first node A and the second nodes B, C, D, E, F, G, H, I, etc., it may be dynamically changed. In other words, when the user B (second node) sets the reverse three-zone (first node) as the region of interest, a predetermined relationship may be formed between the first node and the second node by the intention of the user B. On the contrary, when the terminal of the user C (second node) is within a certain range of the Gangnam station (first node), the user C naturally connects to the Gangnam station (second node) regardless of the user C's intention. Can be formed.

According to other embodiments of the present invention, the first node may have a specific keyword related to the first node as its attribute, and if the specific keyword is included in the information generated and uploaded through the second node, A relationship can be established between the first node and the second node. In other words, if user D is not currently located on the southern ring road, but is watching a news at home, and encounters a traffic jam due to a fire on some section of the southern ring road, he is at home on the southern ring road ab. When information is generated and uploaded due to a section fire due to section congestion, a relationship with a southern circulation road (first node) may be formed due to a specific keyword of 'Southbound circulation road' uploaded by the second node.

As described above, the relationship between the first node and the second node is not only maintained statically, but also has a relationship that continuously changes according to the positional relationship, keyword relationship, and the like, and is formed around a specific node. Networks can generate information that is very relevant to a particular node.

As such, the existing social network can be formed only by the request between the user and the user by the social relationship between the user and the user, while the social network created by the present invention proceeds to the formation of the relationship and the positional relationship of each node. Depending on the relationship can be formed. As a result, various types of traffic information that may be of interest in a specific region or various types of information generated and uploaded by various entities around a specific location may form a social network. According to this feature, the social network according to the present invention can continuously change its constituent nodes over time.

According to an embodiment of the present invention, as described above, the social network 100 may be formed, and the second terminal 400 may receive various information through the social network 100. However, the idea of the present invention is not limited to the communication of various electronic devices through a social network.

On the other hand, the information collection module 222 determines, among the information collected through the second communication unit 210, meets a predetermined condition, and if it does not meet the condition, and collects the collected information in the database ( The filtering operation may be performed without discarding the data in 230 or temporarily storing the data in the database 230 and discarding the data. For example, in consideration of information corresponding to the same section and / or location among the collected information (hereinafter referred to as the same section information), an average value and / or deviation of information obtained from the same section information is calculated. Afterwards, information outside the predetermined reference range may be filtered without being stored in the database 230.

In addition, the second control unit 220 may perform an operation of providing evaluation information to the collected information. Evaluation information given to the collected information may be calculated by various criteria.

The condition processing module 224 performs a function of processing condition information received from the second terminal 400 through the second communication unit 210. As will be described in detail below, in particular, the condition processing module 224, based on the condition information, meets a condition from among information stored in the database 230 or from information on the network 100. You can search for information. For example, the condition processing module 224 extracts information corresponding to the condition information from among the information stored in the database 230. The information extracted by the condition processing module 224 may be different from each other depending on the contents of the condition. The information extracted as described above will be defined as a dynamic information group in this document. The condition processing module 224 generates the dynamic information group based on the condition information will be described in detail later.

The information transmission module 226 performs a function of transmitting predetermined information to the second terminal 400 with reference to the dynamic information group. When the information transmitting module 226 transmits the information to the second terminal 400, the reference amount is determined based on a predetermined amount of information (information included in the dynamic information group) to be transmitted to the second terminal 400. When exceeding, only some of them may be transmitted to the second terminal 400. In this case, the information transmission module 226 may first select a part of the information to be transmitted based on various criteria. For example, the information transmission module 226 may first select information to be transmitted in consideration of evaluation information provided to the information.

Hereinafter, a method of acquiring and collecting information by the interaction of the first terminal and the server under the above-described system environment will be described. For convenience of description, hereinafter, the first terminal 300 and the second terminal 400 described with reference to FIG. 2 will be described as being implemented by the navigation 10 described with reference to FIG. 4. Furthermore, in the case where there are specific electronic devices corresponding to the first node and the second node described with reference to FIG. 3, the specific electronic devices will also be described with reference to FIG. 4. do. However, the inventive concept is not limited to the implementation of the first and second terminals 300 and 400 and / or electronic devices corresponding to the first and second nodes by the navigation device 10.

6 is a flowchart illustrating an information acquisition method according to embodiments of the present invention.

The navigation device 10 and 300 may acquire various information through the input unit 120 (S100).

For example, information directly input by the user by the user input module 121 may be obtained. Alternatively, the sound generated in or outside the vehicle in which the user's nurturing or the navigation apparatus 10 and 300 is attached or installed may be obtained through the microphone 123. Alternatively, an image inside and outside the vehicle to which the navigation devices 10 and 300 are attached or installed may be obtained through the image acquisition module 125. Hereinafter, the information obtained through the input unit 120 of the navigation 10, 300 may be referred to as user content. The user content may include traffic related information, and the user content may be referred to as traffic related content.

The navigation device 10 and 300 may acquire location information (S110).

For example, the navigation 10, 300 calculates a coordinate value (eg, longitude and latitude coordinates) at which the navigation 10, 300 is currently located by using the GPS signal received by the location data module 111. can do.

Subsequently, the navigation 10, 300 may transmit the user content to the server 200 (S120).

In this case, the navigation 10 and 300 may transmit the obtained location information to the server 200. The navigation 10 and 300 may transmit visual information to the server 200 together with the location information.

The location information may be location information calculated before and after the time point at which the user content is obtained.

The location information may be transmitted to the server 200 while the user content is obtained, may be transmitted together while the user content is transmitted to the server 200, and the user content may be transmitted to the server 200. May be sent after

The location information may correspond to the user content. For example, when the first user content acquired by the navigation 10, 300 is generated at the A location, and the second user content is generated at the B location, the first user content may correspond to the A location. The second user content may correspond to the B position.

Meanwhile, location information corresponding to one content may be plural. While acquiring the third user content, the location of the navigation 10, 300 may change with time, and accordingly, a plurality of location information may correspond to the third user content. For example, when the third user content is a driving image acquired while driving on a road, the navigation 10,300 is located at the C position at the time when the driving image is acquired, and a predetermined time when the driving image is acquired. When the navigation (10,300) is located at the D position at this point in time, and the navigation (10,300) is located at the E position at the end of the acquisition of the driving image, the location information corresponding to the third user content is the C location, It can be a D position and an E position. Of course, three or more pieces of location information may correspond to one piece of content, or one piece of location information may correspond to each other.

As described above, visual information may correspond to user content. The way in which the visual information corresponds is the same as or similar to the method in which the location information corresponds to the user content.

The navigation 10 and 300 may further calculate speed information, direction information, section information, etc. corresponding to the user content. When speed information, direction information, section information, etc. are further calculated, the calculated information may be transmitted to the server 200.

The speed information, the direction information, and the section information corresponding to the content may be a specific road section to which the moving speed, the moving direction, and the location of the navigation 10, 300, respectively, calculated while the user content is acquired. Can be.

For example, when the first terminal 300 is located in 'Yangjae Station', when the user of the first terminal 300 inputs information 'slowing from Yangjae Station to Gangnam Station', the user inputs the information. Along with the information, the location information 'Yangjae station' may be transmitted to the server 200 together. The location information may be obtained by the location data module 111 described above. In addition, the location information may be transmitted in the form of text 'Yangjae Station', or may be transmitted in the form of longitude coordinates and latitude coordinates obtained by the location data module 111.

In addition, when the first terminal 300 transmits the information to the server 200, the first terminal 300 may transmit direction information related to the obtained information. The direction information may reflect the direction that the first terminal 300 is in progress when the information is obtained by the first terminal 300. For example, when the first terminal 300 is proceeding from 'Yangjae Station' to 'Gangnam Station' on Gangnam-daero, the user through the microphone 123 of the first terminal 300 toward 'Gangnam Station from Yangjae Station'. When the upbringing of 'communication seamless' is obtained, the upbringing (ie, voice information) of the obtained user may be transmitted to the server 200 together with the direction information.

The speed information may be calculated by a plurality of position information obtained as described above. For example, when the location information is periodically acquired, the moving speed of the navigation device 10 may be calculated by using a distance between the plurality of location information and a preset acquisition period. Alternatively, the speed information may be directly obtained from a vehicle in which the navigation 10 and 300 are installed. For example, speed information of the vehicle may be obtained from an engine control unit (ECU) installed in the vehicle.

The direction information may be calculated by a plurality of location information obtained as described above. For example, when a plurality of location information is acquired while acquiring user content, the direction information may be calculated by a direction of a trajectory formed by the plurality of location information.

The section information may be calculated by a plurality of location information obtained as described above. For example, when the plurality of location information is included in a road section (eg, Teheran-ro Yeoksam Station-Gangnam Station section) on the map data, the road section on the map data may be the section information.

Meanwhile, according to another embodiment of the present invention, the location information and / or the direction information may be information extracted from information to be transmitted (that is, user content).

For example, when the user inputs 'Gwacheon-dong communication in Yangjae-daero' through the first terminal 300, the first terminal 300 receives location information and / or direction information from information input by the user. Can be extracted. That is, 'Yangjae-daero' may be extracted as location information, and 'Gwacheon direction' may be extracted as direction information.

Alternatively, according to another embodiment of the present invention, the location information may reflect a location attribute assigned to a node related to input information (ie, user content).

For example, when 'Gangnam Station' exists as a first node, the first terminal 300 is a second node having a relationship with the 'Gangnam Station', and the 'crossroad signal failure' for the node named 'Gangnam Station'. In this case, the inputted information may be transmitted to the server 200 together with the corresponding Gangnam station. If direction attributes are also assigned to the first node, direction information reflecting the direction attributes assigned to the first node may be transmitted to the server 200.

As described above, the information calculated by the embodiments of the present invention may be transmitted to the server 200 while the user content is obtained, and may be transmitted together while the user content is transmitted to the server 200. The user content may be transmitted after being transmitted to the server 200.

On the other hand, according to an embodiment of the present invention, the navigation (10,300) may transmit only the location information and / or time information corresponding to the user content to the server 200, accordingly, the above-described speed information, direction The information, section information, etc. may be calculated by the server. The method of calculating the speed information, the direction information, and the section information by the server 200 is the same as or similar to the method calculated by the navigation 10, 300. That is, the server 200 may calculate the speed information, direction information, section information, etc. using the plurality of location information received from the navigation 10, 300. Alternatively, the server 200 may extract the direction information, location information or section information from the user content received from the navigation 10, 300. Alternatively, the server 200 may obtain the location information from the location attribute assigned to the node associated with the user content received from the navigation 10, 300.

As described above, information (user content) may be obtained by the first terminal 300, and the obtained information may be transmitted to the server 200. In addition, the information (user content) may correspond to any one or more of location information, speed information, direction information, and section information.

Hereinafter, a method of collecting and storing information under the above-described system environment will be described.

7 is a flowchart illustrating an operation method for collecting and storing information of a server according to embodiments of the present invention.

First, as described above, the server 200 receives various information (for example, traffic related content) from the network 100 (S200).

The received various types of information may include traffic related information, traffic information, information on a specific point of interest (hereinafter, referred to as a “point of interesting”), chat information, and the like. In addition, the received various types of information may correspond to visual information, location information, direction information, and speed information related thereto. In addition, the various types of information may correspond to identification information of a user who has transmitted the various kinds of information or a terminal of the user. The identification information of the user or the terminal of the user may be transmitted from the navigation 10, 300 to the server when the user content is transmitted.

Subsequently, the server 200 stores the received information in a database (S210).

The received information may optionally be stored. That is, all of the received information may be stored, or only part of the received information may be stored. For example, the server 200 may selectively store only the information meeting the criteria after evaluating the content of the information received through the social network 100 according to a predetermined criterion. The predetermined criterion may be determined by reflecting the purpose of information to be provided from the server 200 to the navigation device 10. For example, if the user wants to transmit traffic related information to the navigation device 10, the server 200 may determine whether the received information includes traffic related information, and does not include traffic related information. If determined, the received information may be discarded without storing. Hereinafter, the operation of the server 200 selectively storing the received information in the database will be referred to as a 'filtering operation' or 'filtering'.

The server 200 may store the received information (that is, user content) in the database and map the data to the navigation map data. At this time, the server 200 may map the received information to the map data using location information and / or section information corresponding to the information.

The information may be classified and stored according to location information and / or section information. For example, the information may be classified and stored by administrative districts such as city, county, and district, and may be stored separately by roads such as outer ring road, southern ring road, and Olympic road. Alternatively, the subdivision may be classified and stored for a section of a predetermined road such as A-B section of the outer circulation road and C-D section of the southern circulation road.

Furthermore, the information may be classified and stored in consideration of the direction information included in the information. For example, it may be classified and stored in the A direction of the A-B section of the outer ring road or the B direction of the A-B section of the outer ring road.

The server 200 may further classify and store the speed information corresponding to the information.

The server 200 may add evaluation information to the information and store the evaluation information together. The evaluation information may be representative of the reliability of the information. For example, a higher grade of the evaluation information may indicate that the information is of higher reliability, and conversely, a lower grade of the evaluation information may indicate that the information is of lower reliability.

There may be a wide variety of ways of providing evaluation information to the information. For example, it may be calculated in consideration of the evaluation information given to the user or the terminal that transmitted the information. Alternatively, when the information includes traffic related information, the evaluation information may be calculated in consideration of a result compared with traffic information provided from another traffic information providing server.

On the other hand, the server 200 may discard the information after a predetermined time after the information is obtained using the time information corresponding to the information.

As described above, the information collected by the server 200 may be transmitted to the second terminal based on various conditions and / or information received from the second terminal.

Hereinafter, a method of receiving information by the second terminal in the above-described system environment will be described.

8 is a flowchart illustrating a method of operating a server and a second terminal according to embodiments of the present invention. Hereinafter, for convenience of description, it will be described on the assumption that the second terminal 400 is implemented by the above-described navigation 10.

In this case, the second terminal 400 may obtain a predicted path of the vehicle based on the current location and the driving road, and transmit the obtained predicted path to the server 200. (S300).

The current position refers to the current position of the vehicle to which the second terminal 400 is attached or installed, and the current position may be calculated by the position data module 111. The current position may include a longitude coordinate value and a latitude coordinate value.

The driving road refers to a road on which the vehicle to which the second terminal 400 is attached or installed is currently traveling.

The predicted path of the vehicle refers to a path that the vehicle is expected to proceed in the future, and the second terminal 400 may acquire the predicted path by using various algorithms. Specific methods for obtaining the expected path will be described later in more detail.

When the second terminal 400 transmits the expected route to the server 200, the server 200 may obtain traffic related content based on the received expected route (S310).

For example, the server 200 may obtain traffic-related content mapped to the expected path from the various pieces of information (traffic-related content) collected as described above.

According to an embodiment of the present invention, the server 200 may select some traffic-related content in consideration of the received expected route.

For example, the server 200 may select traffic-related content transmitted from the first terminals 300 located on the expected path among a plurality of stored traffic-related contents.

Alternatively, as described above, traffic-related contents may be mapped to navigation map data based on location information and / or section information corresponding to the traffic-related contents, and the server 200 may map onto the expected path. Traffic related content can be selected.

The server 200 may select some of the collected traffic-related content in consideration of the received expected path and transmit the selected content to the second terminal 400 (S320).

According to an embodiment of the present invention, the server 200 may store the information obtained by the first terminal 300 as it is, and transmit it to the second terminal 400 without any processing. For example, when the driving image acquired by the first terminal 300 while driving the vehicle is photographed, the server 200 receives / stores the captured image and meets the condition in which the driving image is received. In this case, the video may be transmitted to the second terminal 400 without any additional processing.

In contrast, according to another exemplary embodiment of the present invention, the server 200 stores the information obtained by the first terminal 300 and processes the information before transmitting the information to the second terminal 400. After that, the processed information may be transmitted to the second terminal 400. Methods of processing information can vary.

When the server 200 transmits the traffic-related content selected based on the expected route, the second terminal 400 may receive the traffic-related content and output the received traffic-related content (S330).

The second terminal 400 may output the traffic related content through the output unit 140. That is, the second terminal 400 may visually output the traffic related content through the display module 141 and may output the traffic related content audibly through the audio output module 143. have.

On the other hand, if the traffic-related content includes text data and no sound data, the second terminal 400 converts the text data into sound data and outputs the sound data through the audio output module 143. can do. For example, the text data may be converted into acoustic data through a text to speech (TTS) module.

As such, according to embodiments of the present invention, the server 200 may collect various types of information from the social network 100 formed by various relationships, and among these information, received from the second terminal 400. In consideration of the estimated route, the selected information is selected and then the selected information can be transmitted to the second terminal 400 to provide only the necessary information to the second terminal 400.

Hereinafter, a method of obtaining an expected path according to embodiments of the present invention will be described.

9 to 11 are diagrams for explaining a method of obtaining an expected path according to embodiments of the present invention.

First, the second terminal 400 may determine whether there is a fork in the driving road of the vehicle. The branch point may include an access road and / or an access road on an expressway, an intersection on a general road, and the like, and the second terminal 400 may be a predetermined reference distance from the current location C1 of the vehicle on a driving road. It is possible to determine whether there is an access road, access road, and / or intersection within the road.

FIG. 9 illustrates a case where a vehicle is positioned on a first driving lane L1 on a driving road and there is no branch point within a predetermined distance from the current position C1 of the vehicle. In this case, the second terminal 400 may predict that the vehicle will continue straight along the driving road, and may obtain the predicted route PP1 accordingly. Accordingly, when the second terminal 400 transmits the acquired prediction path PP1 to the server 200, the server 200 searches / acquires traffic-related contents mapped to the prediction path PP1. To the second terminal 400. At this time, the server 200 sets a search range SR1 in consideration of the moving speed and / or the moving direction of the second terminal 400, and the expected path PP1 within the set search range. It can search / acquire traffic related contents mapped to.

On the other hand, FIG. 10 illustrates a case where there is a branch point (for example, an advance road) within a predetermined reference distance from the current positions C1 and C2 of the vehicle on the driving road. In this case, the second terminal 400 may determine the driving lane of the vehicle and obtain an expected path based on the determined driving lane.

The second terminal 400 may use various methods in determining the current position of the vehicle. For example, an external image of the vehicle acquired by the image acquisition module 125 may be analyzed, and a driving lane of the vehicle may be determined based on the analyzed image. Alternatively, the driving lane of the vehicle may be determined based on latitude and longitude coordinate values obtained by the position data module 111.

Meanwhile, the second terminal 400 may acquire progress information provided to the driving lane from the map data based on the driving lane of the vehicle, and may obtain an expected path based on the driving information.

For example, when the location of the vehicle is at C2, the second terminal 400 may recognize that the vehicle is located in the second driving lane L2, and the progress information allocated to the second driving lane L2 is turned right. In this case, the second terminal 400 may acquire the expected route PP2 exiting from the fork in the driving road to the advance road.

Meanwhile, when the location of the vehicle is at C3, the second terminal 400 recognizes that the vehicle is located in the third driving lane L3, and determines from the map data that the progress information allocated to the recognized driving lane is straight. have. In this case, the second terminal 400 may acquire the expected route PP3 that continues straight at the branch point of the driving road.

Accordingly, when the vehicle is located at C2, the server 200 searches for and acquires traffic related content mapped to the predicted route PP2 received from the second terminal, and transmits it to the second terminal 400.

11 shows a case where the type of branch point is an intersection. Even when the branch point is an intersection, as described with reference to FIG. 10, the second terminal 400 determines the driving lane of the vehicle, and the driving direction information assigned to the driving lane with reference to the determined driving lane and map data. After obtaining, an expected path may be obtained.

That is, when an intersection (branch point) exists within a predetermined distance from the vehicle on the driving road, the second terminal 400 may determine the current driving lane and obtain different expected paths according to the determined driving lane. have.

For example, when the vehicle is located at C4, the driving lane is recognized as L4, and accordingly, the second terminal 400 refers to the traveling direction information (right turn) assigned to L4, thereby predicting the route PP4. Can be obtained. Also, when the vehicle is at C5, the predicted path PP5 can be obtained, and when the vehicle is at the C6 position, the predicted path PP6 can be obtained.

The predicted path obtained by the method as described above may be transmitted to the server 200 as described above, and the server may search / acquire traffic related contents mapped on the predicted path based on the transmitted predicted path. In this case, the data may be transmitted to the second terminal 400 again.

Hereinafter, a method of outputting traffic-related content received based on an expected route related to embodiments of the present invention will be described. 12 to 15 are diagrams for describing a method of outputting traffic-related content according to embodiments of the present invention.

FIG. 12 illustrates an example of a screen output through the second terminal 400 when the vehicle is located at the position C4 of FIG. 11.

When the second terminal 400 receives the traffic-related content, as shown in FIG. 12, the display terminal 141 includes a content display area for displaying traffic-related content together with a route guidance area for general route guidance. Can be provided via

12 illustrates a case where the vehicle is located at the position C4, the traffic-related content illustrated in FIG. 12 is mapped onto the predicted route PP4 illustrated in FIG.

FIG. 12 illustrates that traffic related content is visually displayed through the display module 141. However, as described above, when the traffic related content includes sound data, the sound data is the audio output module 143. ) Can be output acoustically. Furthermore, text information included in traffic-related content may be converted into sound data and output through the audio output module 143 according to a user's selection.

In addition, although FIG. 12 illustrates that the screen of the second terminal 400 is divided into a traffic guide content for a general route guidance area and a content display area for displaying traffic related content, the content display area is shown in FIG. May be output in picture in picture (PIP) format.

In the above description, the second terminal 400 acquires one predicted path based on the current position of the vehicle, but the second terminal 400 may obtain a plurality of predicted paths.

When a specific event occurs, the second terminal 400 may obtain a plurality of expected paths based on the current location of the vehicle. For example, when there is a branch point such as an intersection or an entrance / exit road within a predetermined distance range from the driving road of the vehicle, a plurality of predicted paths traveling in all the traveling directions at the branch point may be obtained.

For example, as shown in (a) of FIG. 13, when the current position C7 of the vehicle enters within the first reference distance at the intersection, the second terminal 400 faces A and B at the intersection. In this case, a plurality of predicted paths through each of the C directions can be obtained. In this case, the second terminal 400 may transmit all of the obtained plurality of expected routes to the server 200, and the server may search / acquire traffic related contents mapped to each of the transmitted plurality of predicted routes. 2 may be transmitted to the terminal (400).

Accordingly, as illustrated in (b) of FIG. 13, traffic related content mapped to the A direction, traffic related content mapped to the B direction, and content mapped to the C direction may be displayed in the content providing area. have.

At this time, the traffic-related contents may be displayed grouped for each direction.

In addition, when there are a plurality of traffic-related contents mapped to each area, only some, but not all of the traffic-related contents mapped to each area may be displayed. For example, if there are three directions (eg, straight, left, right) at the fork, such as at a crossroads, the content display area can be divided into three sections for high visibility. When all of the traffic-related contents mapped to the divided region cannot be displayed, only a part of the traffic-related contents may be displayed. For example, if there are 10 traffic-related contents mapped for the A direction, and 3 traffic-related contents can be displayed in the area allocated for the A side, only 3 out of 10 may be displayed.

When only a part of traffic-related content that is mapped is to be displayed, the second terminal 400 allocates priority in consideration of the evaluation information assigned to each traffic-related content by the server, and then assigns priority to the priority. The display order can be determined accordingly.

When the server 200 searches / acquires traffic-related content mapped to the expected path, the server 200 may set a range for searching for traffic-related content. The range may have a predetermined pattern and may be determined in consideration of the current position and the moving direction of the second terminal 400.

For example, referring to FIG. 14A, the server 200 may set a search range having a first pattern PT1. The first pattern PT1 may be formed in a fan shape formed by using a point E located at a first distance D in a moving direction of the vehicle from a current position C of the vehicle as a vertex. The center angle ag and the first distance D of the formed fan shape may be determined according to the moving direction of the vehicle and / or the moving speed of the vehicle.

For another example, referring to FIG. 14B, the server 200 may set a search range having a second pattern PT2. The second pattern PT2 is a vertex facing the point E2 positioned at the second distance D2 in the moving direction of the vehicle from the current position C of the vehicle as one vertex. It may be formed into a rhombus shape. The second distance D2 and another diagonal length D3 of the rhombus may be determined according to the moving direction of the vehicle and / or the moving speed of the vehicle.

For another example, referring to FIG. 14C, the server 200 may set a search range having a third pattern PT3. The third pattern PT3 may be formed in a fan shape having the current position C of the vehicle as a vertex and having a radius of a predetermined length D4. The predetermined length D4 and the center angle ag2 of the fan shape may be determined according to the moving direction of the vehicle and / or the moving speed of the vehicle.

The server 200 may search / acquire traffic related contents mapped within the search range set as described above among the traffic related contents mapped to the expected path.

As described above, when the second terminal 400 obtains a plurality of predicted paths and receives / outputs traffic-related content corresponding thereto, as shown in FIG. When the current location C8 enters within the second reference distance, as described above, after determining the driving lane of the vehicle, one predicted path may be obtained based on the determined driving lane. That is, as shown in FIG. 15A, when the vehicle is traveling along the right lane and the traveling direction corresponding to the right lane is a right turn, the second terminal 400 is an expected path toward the A direction. (PP) can be obtained. Accordingly, as illustrated in FIG. 15B, the second terminal 400 may display traffic related content mapped to the expected route PP in the content display area.

In the above description, an embodiment in which the second terminal 400 obtains a plurality of predicted paths according to a predetermined criterion and directly outputs traffic-related content corresponding to the plurality of predicted paths, is described. When the plurality of predicted paths are obtained, objects corresponding to the predicted paths may be displayed, and then traffic-related content mapped to the predicted paths corresponding to the selected objects may be output according to selection of the objects.

16 to 18 are diagrams for describing a method of displaying an object corresponding to a plurality of expected paths according to embodiments of the present invention.

FIG. 16 is a sub-window for displaying an object OB1 corresponding to a plurality of predicted paths on a screen displayed through the display module 141, and providing a path guide area for path guidance. SW1) is provided. The sub-window SW1 displays a shape of an intersection located on a driving road of the vehicle, and the respective objects OB1 are provided at positions corresponding to respective traveling directions of the intersection.

In this case, the objects OB1 may reflect information corresponding to a traffic situation mapped to an expected path corresponding to each direction of the intersection. For example, the objects OB1 may include text information indicating the traffic situation. Alternatively, the display object OB1 may be assigned a display attribute determined according to the traffic condition, and each object OB1 may be displayed according to the assigned display attribute. FIG. 15 illustrates a case in which the objects OB1 include text information reflecting traffic conditions of an expected route corresponding to each direction, and FIG. 16 illustrates objects OB2 corresponding to each direction. The case where the color attribute which reflects the traffic condition of an expected path is provided is shown.

Meanwhile, the traffic situation mapped to the predicted paths corresponding to each direction of the intersection may be determined based on the contents of the traffic-related content mapped to each of the predicted paths. That is, when there are five traffic-related contents mapped to one predicted route, four pieces of information indicate smooth traffic conditions on the predicted route, and one piece of information indicates that the traffic situation is slow. Traffic conditions mapped to predicted paths can be given smoothly.
