Referring to FIG. 1, a system environment related to embodiments of the present invention may include a plurality of electronic devices 100, 400, a server 200, and a network 300.

The plurality of electronic devices 100 and 400 may be a fixed terminal or a mobile terminal. Examples of the plurality of electronic devices 100 and 400 include a navigation device, a smart phone, a mobile phone, a computer, a laptop computer, a digital broadcasting terminal, a PDA (Personal Digital Assistants) (Portable Multimedia Player), MID (Mobile Internet Device), and Tablet PC (Tablet PC).

Hereinafter, the plurality of electronic devices 100 and 400 will be referred to as a first terminal 100 and a second terminal group 400. [ The second terminal group 400 may include at least one electronic device.

1, it is assumed that the first terminal 100 is a navigation terminal, and the second terminal group 400 is a smart phone 400a, a tablet PC 400b, and a notebook computer 400c will now be described.

Each of the electronic devices 100 and 400 can communicate with other electronic devices by a wireless or wired communication method. In this document, the manner in which the electronic apparatuses 100 and 400 communicate with each other is not limited. The technical spirit of this document may be applied to all wireless communication methods between existing electronic devices and all future communication methods.

For example, each of the electronic devices 100 and 400 can communicate with each other by a communication method such as UPnP (Universal Plug and Play), WiFi, or the like. For example, each of the electronic devices 100 and 400 can communicate with each other via the network 300 or by a local communication method. Examples of the network 300 include a mobile communication network, a wired Internet, a wireless Internet, and a broadcasting network.

The second terminal group 400 may transmit information to the server 200 or the first terminal 100 through the network 300. [ The second terminal group 400 may acquire various types of information such as text information, image information, and sound information, and the obtained information may be transmitted to the server 200 through the network 300 . In particular, the information transmitted from the second terminal group 400 to the first terminal 100 through the server 200 or directly from the second terminal group 400 includes traffic information, a specific point of interest (hereinafter, referred to as 'POI' , Chatting information, and the like.

The server 200 may access the network 300 and search / receive information transmitted from the second terminal group 400. [ The received information may be stored in the server 200.

Meanwhile, the server 200 may continuously monitor the position of the second terminal group 400. [ For example, the first terminal group 400 receives location information from the plurality of electronic devices 400a, 400b, and 400c included in the second terminal group 400 and transmits the location information to the second terminal group 400 based on the received location information. The position of the plurality of electronic devices 400a, 400b, and 400c included in the plurality of electronic devices may be continuously monitored.

Meanwhile, the server 200 periodically receives the location information from the plurality of electronic devices 400a, 400b, and 400c included in the second terminal group 400, or when the specific event occurs, Location information can be obtained.

At this time, the location information may be transmitted at the request of the server 200. The second terminal group 400 may be connected to the second terminal group 400 without any special request from the server 200 when the second terminal group 400 detects occurrence of a predetermined event. And may transmit the location information to the server 200. [

The server 200 may also monitor the location of the first terminal 100. The method of monitoring the location of the first terminal 100 is similar to or similar to the method of monitoring the location of the second terminal group 400.

The first terminal 100 may transmit condition information related to a traffic situation to the server 200. [ The server 200 may transmit the information conforming to the condition requested by the first terminal 100 to the first terminal 100 in consideration of the condition information received from the first terminal 100 . Accordingly, the server 200 may configure customized information for the first terminal 100 and transmit the customized information to the first terminal 100.

The network 300 may be implemented in a variety of ways.

For example, the network 300 in accordance with embodiments of the present invention may include a social network.

Also, for example, the network 300 may include a mobile communication network, a local area network (e.g., WiFi), and the like.

2 is a conceptual diagram for explaining the social network related to one embodiment of the present invention.

Social networks is one of the research fields of web science. It refers to a social relation structure that is created by interdependent ties between individual nodes or individuals as a single node. In this case, all the nodes are individual subjects in the network, and ties are the relationships between the nodes (above, Wikipedia).

The social network according to the present invention may include at least one second node B, C, D, E, F, and B having a relationship with a first node A, centering on a first node (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,

For example, when the first node A is a specific user, another user or terminals having a relationship with the user can configure the social network 300 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 300 together with the specific road as a second node .

When the first node A is a specific building, another building, road, terminal or users having a relationship with the specific building can configure the social network 300 together with the specific building as the second node .

If the first node A is in a specific location, another location, road, building, terminal or user having a relationship with the specific location is configured as a second node with the specific location to configure the social network 300 .

Since the social network 300 according to the present invention is formed around a specific node, various social networks 300 can be configured according to a specific node. For example, when the specific node is a 'southern ring road', a 'star tower', a 'Gangnam station', a 'Yeouido', etc., information networks formed around the specific nodes may be different from each other. At this time, although each information network may not coincide with each other, some of other nodes included in one information network may be included in another information network. For example, assuming that the user A and the user B are included in the network 300 formed around the node 'southern circuit road', the user A and the user B are connected to the network 300 formed around the node ' And user C may be included. That is, the node A may be included both in the network formed around the 'southern ring road' and in the network formed around the 'star tower'.

At this time, the nodes A, B, C, D, E, F, G, H, and I may preferably have corresponding location attributes. For example, when the nodes are a specific location, a specific road, or the like, the location of the specific location, the specific road, and the specific building may be a location attribute corresponding to the node, The current location of the particular terminal or the specific user may be a location attribute corresponding to the node.

In addition, the first node A can be distinguished as a static node and a dynamic node, which means a node whose positional property corresponding to the specific location, specific road, specific building, etc. does not change, A node means a node whose positional attribute, such as the specific user or the specific electronic device, can be changed 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 nodes B, C, E, F, G and I define a primary relation with the first node A, and the nodes D and H are connected to the first node A I have a relationship. Of course, although not shown in the drawing, if there is no relation with B, C, E, F, G, and I, and there is a node that is associated with any one of the D and H nodes, Can be defined to have a cubic relationship with the first node (A).

In this way, the existing social network can be formed only by the request between the user and the user according to the social relation between the user and the user, while the social network according to the present invention goes beyond this relationship, A 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 characteristic, the nodes constituting the social network according to the present invention can be continuously changed over time.

Hereinafter, in the present invention, it is assumed that the network 300 is the social network described with reference to FIG.

The controller 230 is connected to the electronic devices 100 and 400 through the network 300. When user authentication is required for each of the electronic apparatuses 100 and 400, the authentication information received from each of the electronic apparatuses 100 and 400 is used to identify a user And performs the authentication process.

Also, the controller 230 acquires user contents, traffic flow information, and traffic related contents through communication with the electronic devices 100 and 400, and stores the contents in the storage unit 220.

The user contents are contents generated by the electronic apparatuses 100 and 400. The control unit 230 can acquire user contents from the electronic devices 100 and 400 connected through the communication unit 210.

For example, the controller 230 may transmit the traffic-related contents corresponding to the specific location to the navigation system 100 when the navigation-related content is requested from the navigation system 100.

Also, at least one criterion for selecting the traffic-related contents may include area information. For example, the control unit 230 may transmit the traffic-related contents corresponding to the specific area to the navigation unit 100 when the navigation-related content is requested from the navigation unit 100.

In addition, the at least one criterion for selecting the traffic-related contents may include time information. For example, the controller 230 may transmit the traffic-related contents corresponding to the specific time to the navigation system 100 when the navigation-related contents are requested from the navigation system 100. As an example, the navigation 100 may transmit traffic-related content that is obtained within a certain time or obtained after a certain time.

In addition, the at least one criterion for selecting the traffic-related content may include direction information. For example, the controller 230 may transmit the traffic-related content corresponding to a specific direction to the navigation device 100 when the navigation device 100 requests the navigation device 100 to provide the traffic-related content. For example, the control unit 230 may store traffic-related contents acquired through communication with at least one of the plurality of electronic devices 400, which are located in a specific direction with respect to any one of the positions, Can be transmitted to the navigation system 100.

At least one criterion for selecting the traffic-related content may be directly received from the navigation device 100 requesting the traffic-related content provision, or may be acquired based on the position of the navigation device 100. [ For example, the controller 230 may receive direction information indicating a specific direction from the navigation system 100, and may select the traffic-related contents transmitted to the navigation system 100 based on the direction information. Also, for example, the controller 230 may acquire a moving direction of the plurality of electronic devices 400 based on the position of at least one of the plurality of electronic devices 400 acquired for a predetermined time, Related content to be transmitted to the navigation system 100 may be selected.

In addition, the controller 230 supports the social network 300 between the electronic devices 100 and 400. For example, when at least one criterion for selecting the plurality of electronic devices 400 constituting the social network 300 is received from the navigation device 100, the plurality of electronic devices 400 And at least one electronic device and the navigation device 100 constitute the social network 300. At least one criterion for selecting the plurality of electronic devices 400 included in the social network 300 is similar to at least one criterion for selecting the traffic-related content and can be obtained in a similar manner.

The control unit 230 also supports reconfiguration of the network 300 based on a change in position of the electronic devices 100 and 400 included in the social network 300. [ For example, the social network configured based on the current position of the navigation system 100 may be reconfigured based on the changed position as the current position of the navigation system 100 is changed. A new electronic device may be added to the network 300 or may be included in the network 300 based on a change in position of the plurality of electronic devices 400 included in the network 300. For example, The electronic device may be excluded from the network 300.

The control unit 230 generates traffic flow information based on the location of each of the electronic devices 100 and 400 included in the social network 300 and transmits the traffic flow information to the respective electronic devices 300 and 300 included in the social network 300. [ Can be transmitted to the devices (100, 400). For example, the controller 230 acquires a position of the electronic device 100 or 400 included in the social network 300 for a predetermined period of time, The moving direction of the vehicle, and the traveling speed. Then, the acquired traffic flow information is transmitted to each of the electronic devices (100, 400) included in the social network (300).

Hereinafter, a traffic information providing method of navigation 100 according to an embodiment of the present invention and an operation of navigation 100 for implementing the method will be described in detail with reference to necessary drawings.

The embodiment disclosed in this document can be implemented in the navigation 100 described with reference to Figs.

First, the operation of the navigation system 100 for implementing the embodiment disclosed in this document will be described in more detail.

The communication unit 110 is connected to the server 200 through the network 300. Also, traffic related contents are received from at least one of the server 200 and the plurality of electronic devices 400.

In addition, the display module 141 displays traffic-related contents obtained through the communication unit 110 on the screen.

The controller 170 obtains the current position of the navigation system 100. [ When the navigation device 100 is mounted on the vehicle, the current position of the navigation device 10 can be used as the current position of the vehicle.

The controller 170 may acquire the current position of the vehicle using the GPS signal obtained through the position data module 111. On the other hand, since there is some error in the received GPS signal, the controller 170 performs a software map matching process on the received GPS signal to match the current position of the vehicle with the current running road . When the vehicle enters the shaded area where the GPS signal can not be received, the control unit 170 acquires the steering direction and the speed information of the vehicle using the gyro sensor included in the sensing unit 130, Can be determined.

In addition, the controller 170 may connect to the server 200 through the communication unit 110. [

The control unit 170 requests traffic-related contents to the server 200 by transmitting a specific location or a search range to the server 200. Here, the search range may include an area, a time, a direction, and the like.

In addition, the controller 170 displays traffic-related contents received from the annoyance server 200 on the screen through the display module 141, thereby providing traffic information to the user.

Next, the traffic information providing method of the navigation system 100 according to the embodiment of the present invention will be described in detail.

5 is a flowchart illustrating a traffic information providing method of the navigation system 100 according to an embodiment of the present invention. 6 to 11 are views for explaining a traffic information providing method according to an embodiment of the present invention.

The traffic information providing method shown in FIG. 5 may be implemented in the navigation 100 described with reference to FIGS.

Hereinafter, for convenience of explanation, it is assumed that the navigation system 100 is mounted on a vehicle.

Referring to FIG. 5, the controller 170 sets a first path 10 to a destination (S100), and performs route guidance based on the first path 10 (S110).

Here, the user of the navigation system 100 may input the destination through the user input module 121 and request a search for a route to the destination.

If the user requests a path search for a destination, the controller 170 may search for at least one path according to a predetermined path search condition, and the user may search for a specific path among the at least one path And may select the first path to the destination. Here, the controller 170 may select one of the searched at least one route as the first route without directly selecting the user.

6 (a) shows an example of a navigation 100 screen for setting a route search condition.

For example, referring to FIG. 6A, the route search condition A may include 'traffic forecast', 'highway priority', 'free road priority', and 'distance priority'. Further, the path search condition A shown in Fig. 6 (a) may be selected by the user.

For example, when the user applies (B) by setting the 'distance priority' (A1) to the path search condition (A) in the search option of the path search menu as shown in FIG. 6 (a) The controller 170 may search for a path on condition that the shortest distance to the destination is detected when searching for the destination. Accordingly, the controller 170 may set the shortest path to the destination as the first path 10. [

The control unit 170 displays the first route 10 on the display module 141 as shown in the navigation 100 screen of FIG. 6B, The route guidance for guiding the first route 10 can be started. At this time, the user can reset the path search condition A by selecting the search option 11. In addition, the route comparison 12 is selected and the distance, time, cost, etc. of the route by the conditions other than the first route 10 and the 'distance priority' (A1) Can be compared. In addition, the route cancellation 13 can be selected to cancel the route guidance by the first route.

Meanwhile, FIG. 7 shows an example of a screen in which route guidance according to the first route 10 is being performed. In the screen shown in Fig. 7, the area C is an area showing the path progress state along the first path 10. [ That is, the controller 170 can display the name of the destination, the remaining distance to the destination, the time required to reach the destination, or the expected arrival time and the route search condition (for example, 'distance priority' have. For example, according to the screen shown in FIG. 7, the remaining distance to the destination 'Gwanghwamoon' C1 is' 13km '(C2), the expected arrival time is' 08:50 am (C3) Distance priority '(C4).

Also, the communication unit 110 may receive the traffic related content from outside while performing the route guidance according to the first route (S120).

The source of the traffic-related content and the route through which the traffic-related content is delivered to the navigation system 100 may vary.

For example, the user contents generated in at least one of the plurality of electronic devices 400 are transmitted to the server 200, and the server 200 transmits the traffic related contents And then transmit the generated navigation data to the navigation device 100. FIG.

Also, for example, the server 200 may generate the traffic-related content based on the traffic information received from the traffic information server and transmit the generated traffic-related content to the navigation device 100. [

Also, for example, the navigation system 100 may transmit user contents generated by at least one of the plurality of electronic apparatuses 400 to the plurality of electronic apparatuses 400 without going through the server 200 Or may be directly received from at least one electronic device.

Examples of the source of the traffic-related contents and the route of the traffic-related contents to the navigation system 100 will be described below in more detail.

Here, the controller 170 may be connected to the server 200 to receive the traffic-related content through the communication unit 110. When the user authentication process for connecting to the server 200 is required, If the user authentication is successful by transmitting the authentication information to the server 200, the server 200 can be connected.

If the traffic information providing function for acquiring the traffic-related contents is not activated, the controller 170 transmits the traffic information to the specific location, the specific area, and the specific route (for example, The server 200 may request the activation of the traffic information providing function to acquire traffic related contents related to at least one of the traffic information providing function and the traffic information providing function. For example, referring to FIG. 8 (a), the user may select an icon 'TCON' (D1) requesting traffic related contents generated from the plurality of electronic devices 400 or traffic related contents from an external server The user can activate the traffic information providing function by selecting the request icon 'TPEG' (D2).

The traffic-related contents may include contents related to a congestion or a cause of a lag, and the congestion or a cause of the lag may include a traffic accident, a construction, a vehicle breakdown, demonstration, a rally, an event, and bad weather.

The traffic-related contents may be acquired based on user contents acquired or generated by at least one of the plurality of electronic devices 400 and transmitted. For example, the user content may include content such as text, video (image, video), audio, and the like.

For example, as described above, the communication unit 110 may transmit user contents generated from at least one electronic device among the plurality of electronic devices 400 directly from the plurality of electronic devices 400, 200), and can acquire the traffic-related content based on the user content.

For example, when the user selects the icon D1 shown in FIG. 8 (a), the controller 170 controls the social network 300 to acquire the traffic- To the server 200. In this case, At this time, the controller 170 may transmit information regarding the current position, the moving direction, the destination, and the search radius of the navigation device 100 to the server 200.

Accordingly, the navigation system 100 can configure the social network 300 with at least one of the plurality of electronic devices 400. Here, the navigation device 100 may be already participating in the social network 300.

In this case, the server 200 may acquire the user content from at least one of the plurality of electronic devices 400 included in the social network 300. The server 200 generates the traffic-related content related to the current position, the moving direction, the destination, and the search radius of the navigation system 100 based on the user content, and transmits the traffic-related content to the navigation system 100 Lt; / RTI >

In addition, the control unit 170 directly receives the user content from at least one of the plurality of electronic devices 400, acquires the traffic-related content based on the received user content, 141).

Here, the control unit 170 may treat the user content received directly from at least one of the plurality of electronic devices 400 as the traffic-related content, or may process the user content according to a predetermined method The traffic-related contents can be obtained.

For example, the controller 170 may receive the navigation data from the navigation system 100 and other navigation devices such as the smartphone 400a, the tablet PC 400b, and the notebook computer 400c that constitute the social network 300 Related information related to the current location, the moving direction, the destination, the search radius, and the like of the mobile terminal 100.

8A is a diagram illustrating the navigation system 100 in which the traffic related contents obtained from at least one of the plurality of electronic devices 400 forming the navigation system 100 and the social network 300 are displayed. Fig.

The social network 300 may be configured based on the current position, the moving direction, the destination, and the search radius of the navigation device 100 while the route guidance according to the first route 10 is performed. Can display information about the congestion or the cause of the delay, which is obtained from at least one of the plurality of electronic devices (400).

For example, referring to FIG. 8A, the controller 170 may display the traffic-related contents (or the user contents) obtained from at least one electronic device among the plurality of electronic devices 400, Can be displayed in the content display area 20 of the module 141. [

As described above, the traffic-related content (or the user content) may be information related to the current position, the moving direction, the destination, the search radius, and the like of the navigation system 100.

For example, the traffic-related contents (or the user contents) shown in FIG. 8A may include first information related to a traffic accident occurring at a specific point or a specific section located on the first path 10 23 and second information 25 related to the traffic flow. The first information 23 and the second information 25 may include at least one of ID and / or thumbnail photographs of the first electronic device and the second electronic device providing the traffic related content (or the user content) Time and average speed of the first electronic device and the second electronic device when providing the traffic-related content (or the user content).

For example, when the user passes through the 'Gangnam Station Crossroad' included in the first path 10 at 08:22 am, the user can access the first information 23 through the first information 23 shown in FIG. 8 (a) It can be seen that a traffic accident occurred on the road of "Hannam Elementary School" of <Hannam Highway North End ~ Hannam Elementary School> section included in route (10). The time when the first information 23 is provided is 'Shin Jae-wook', the time when the first information 23 is provided is 'AM 08:20', and the average speed is 40 km / h &quot;.

In addition, for example, the user can access the section &quot; Hannam Elementary School ~ North Korean Nesting Street &quot; included in the first route 10 at 08:02 am through the second information 25 shown in FIG. 8 (a) The traffic flow on the destination road is smooth.

As described above, the example shown in FIG. 8 is a case where the navigation system 100 obtains traffic-related contents including at least one information 23 related to the occurrence of a traffic accident from outside.

Here, the at least one information 23 related to the traffic accident occurrence may include the image information 21 related to the accident scene. The image information 21 may be a still image or a moving image such as a photograph.

Accordingly, when the user selects the image information 21, a photo or moving image 30 of the accident scene can be reproduced in the content display area 20 as shown in FIG. 8 (b).

Meanwhile, the traffic-related content (or user content) displayed in the content display area 20 may be periodically updated and displayed in the content display area 20 in the order of the latest updated content.

For example, referring to FIG. 9, when the user passes through the 'Namdaemun' included in the first path at 08:50 am, the user selects the first path 10), it can be seen that a vehicle failure occurred at 08:45 am on the road to Gwanghwamun.

For example, the traffic-related content may be generated in the server 200 based on the content received from the traffic information server.

More specifically, when the navigation device 100 requests the traffic-related contents to the server 200, the server 200 requests traffic information from the traffic information server or searches the stored traffic information . At this time, the navigation device 100 may transmit the current position, the moving direction, the destination, and the search radius of the navigation device 100 to the server 200.

The server 200 may extract the traffic information related to the current position, the moving direction, the destination, and the search radius of the navigation system 100, generate the traffic-related content based on the extracted traffic information, and transmit the generated traffic related content to the navigation system 100 .

FIG. 10 is a flow chart illustrating a method of displaying traffic-related contents obtained from the traffic information server by the server 200 on the screen displayed on the display module 141 when the user requests the traffic- Fig.

Referring to FIG. 10, the traffic-related contents acquired from the traffic information server may include flight information indicating various incidents and control situations, and the flight information may include information about a cause of congestion or delay have.

For example, the user can select one of the national escrow information or the escrow information in the route, and when the server 200 requests the escrow information in the route, the server 200 determines the current position of the navigation device 100 , The moving direction, the destination, the search radius, and the like, to the traffic information server.

In addition, the user may select the classification of the unauthorized information including the total information, the control / accident information, the attention information, and other information in requesting the unauthorized information.

Accordingly, the server 200 can generate traffic-related content based on the content received from the traffic information server and transmit the traffic-related content to the controller 170.

For example, as shown in FIG. 10A, the control unit 170 can display traffic information related to a cause such as traffic accident occurrence information, construction information, or the like in the content display area 40 have. At this time, if the user selects the detailed view 40A, detailed contents of the accident occurrence, the time of occurrence, and a photograph or moving picture of the accident scene may be displayed in the content display area 40. [ Referring to FIG. 10 (b), the user has a car / bus collision accident on the road of 'Hannam Elementary School,' which is included in the first route at 08:15 am And the moving image 40B of the accident site can be seen.

In addition, the traffic-related contents may be acquired from at least one of the plurality of electronic apparatuses 400, the traffic information server, and the like, Speed information, and the like.

In addition, when the occurrence of a congestion or a cause of a lag is confirmed on the first route from the traffic-related contents, the controller 170 may obtain a predicted time to resolve the congestion or a cause of the lag [S140].

The control unit 170 may calculate the estimated time to solve the congestion or the cause of the delay by using at least one of the traffic-related contents and the statistical data. Accordingly, the control unit 170 may calculate the expected resolution time in consideration of the estimated time of elimination calculated by the controller 170 and the occurrence time of the congestion or the delay cause included in the traffic information content.

The cause of the congestion or delay may vary. For example, the first information 23 related to the traffic accident shown in Fig. 8 and the defect information shown in Fig. 10 may correspond to the information about the congestion or the cause of the delay, respectively.

In addition, the resolution of the cause of the congestion or delay means a change of the traffic flow from congestion or delay to smoothness. The stagnation state, lag state, slow state, and smooth state can be classified based on the average vehicle moving speed, respectively.

For example, the control unit 170 may obtain the dissolution expected time corresponding to the congestion or delay cause included in the traffic-related content from the statistical data.

FIG. 11 is a table showing an example of statistical data on the estimated time to resolve a congestion or delay depending on the type of congestion or a cause of the congestion. The estimated time to resolve is an average value, which may vary depending on various causes.

Referring to the table on the statistical data shown in FIG. 11, the estimated time for the occurrence of a traffic accident and the resolution of a congestion or a delay due to a faulty vehicle may vary depending on whether the road is a general road or a highway. In addition, the expected time to resolve the stagnation or delay due to bad weather can be different depending on snow removal due to heavy snowfall and whether it is a landslide recovery operation due to heavy rainfall. In addition, the estimated time for resolution may vary depending on the exit / exit time, the size of a traffic accident, the type of construction, and the like.

The statistical data may be obtained from the server 200 or may be a database stored in the memory of the navigation system 100. [ Here, when the statistical data is obtained from the server 200, the statistical data may be updated periodically or irregularly.

Accordingly, the control unit 170 may calculate the estimated time of elimination, which is the time at which the congestion or the cause of the delay is expected to be solved, in consideration of the estimated time of elimination and the occurrence time of the congestion or the cause of the delay included in the traffic information content Can be calculated.

Meanwhile, the server 200 may calculate and estimate the resolution time.

That is, the server 200 may request statistical data on an expected time for resolution according to the type of a congestion or a cause of delay to an internal server such as an external server such as the traffic information server or a statistical data DB server, The expected time of resolution can be calculated based on the statistical data obtained from the server and the occurrence time of the congestion or delay cause included in the traffic information contents.

For example, when the control unit 170 or the server 200 detects the occurrence of a traffic accident on the first route, the controller 170 or the server 200 obtains content related to the traffic accident occurrence The time of occurrence of the traffic accident can be estimated or calculated based on the time.

The time of occurrence of the traffic accident is at least before the time of acquisition of the content related to the occurrence of the traffic accident. Therefore, the control unit 170 or the server 200 regards the acquisition time of the contents related to the traffic accident as the occurrence time of the traffic accident, or the time before the predetermined time Can be determined as the occurrence time of the traffic accident.

The control unit 170 or the server 200 may calculate the expected processing time of the traffic accident using at least one of the traffic-related contents and the statistical data.

For example, referring to FIG. 11, the estimated time for eliminating the traffic accident is about 20 minutes, and the time when the controller 170 acquires the traffic-related contents is 08:20 AM, Can be expected around 08:40 am.

Also, for example, if the traffic-related content includes information related to the estimated time of elimination corresponding to the congestion or a cause of the delay, the control unit 170 may calculate the estimated time of elimination using only the traffic-related content .

The control unit 170 may reflect the estimated time for solving the congestion or the cause of the delay to the route guidance to the destination.

For example, when the controller 170 determines that the expected resolution time is later than the arrival time to the occurrence point of the congestion or the cause of the delay, the control unit 170 may search for the travel route to the destination [S160].

That is, when it is determined that the cause of the congestion or the delay is not solved until the vehicle on which the navigation system 100 is mounted reaches the point of occurrence of the congestion or the cause of the delay, the control unit 170 controls the operation The path can be rediscovered.

In another embodiment, when it is determined that the anticipated release time is later than the arrival time, the control unit 170 may provide the user with a route guidance avoiding the congestion and the section in which the delay occurs. At this time, the control unit 170 may select an alternative route (bypass route) corresponding to the route search condition preset by the user based on the acquired traffic-related content, and provide the selected route to the user.

In addition, as another embodiment, when it is determined that the expected anticipated time for resolution is later than the arrival time, the control unit 170 determines that the path guidance to the destination To the user.

The re-search of the route may be selected by the user or automatically determined.

For example, referring to FIG. 12, the controller 170 displays an expected arrival time 50A of the occurrence of the congestion or a cause of the delay, an expected time of resolution 50B, and a phrase 50C (User Interface) 50 including the user interface 50 may be displayed on the display module 141.

The user can select whether to search for the route through the user interface 50 again.

For example, if the user selects 'No' 50E for the phrase 50C asking whether to search the route again, the controller 170 determines whether route guidance according to the first route currently being performed .

If the user selects 'Yes' 50D for the phrase 50C, the controller 170 may perform an operation of searching for a travel route to the destination.

If it is determined in step S150 that the predicted time of elimination is later than the arrival time to the point of occurrence of the congestion or the cause of the delay, the control unit 170 may automatically Step S160 may be performed.

When the control unit 170 automatically performs the step S160, the control unit 170 may perform the route search for the travel route without providing the user interface 50 shown in FIG.

13 illustrates a case where a traffic accident occurs at a specific point P (51) on the first route 10 while the navigation system 100 is performing route guidance along the first route 10 Fig.

For example, referring to FIG. 13, the control unit 170 determines whether or not the estimated time of elimination of congestion or delay of the traffic accident generated at the specific point P (51) on the first route 10 is 09:15 , And when the estimated arrival time of the specific point (P, 51) is 08:45 am from the current position (52) of the navigation system (100) It is expected that the delay will not be eliminated, so that the route to the destination can be rediscovered.

At this time, the controller 170 may search for the route to the destination according to the set criteria set prior to performing the route guidance based on the first route 10.

For example, when the 'distance preference' condition is set as the path search condition in step S100, the controller 170 may set the 'distance priority' The path can be re-searched as a condition.

However, the control unit 170 may ignore the route search condition at the time of setting the first route 10 and re-search the route by considering only the time required to reach the destination, 10), it is possible to re-search the route by taking both the route search condition and the time taken to reach the destination.

On the other hand, if it is determined in step S150 that the expected time for resolution is earlier than or equal to the arrival time to the point of occurrence of the congestion or the cause of the delay, the control unit 170 searches for the travel route to the destination The route guidance for the first route currently being performed can be maintained (S110).

For example, when the expected arrival time of the specific point P 51 from the current position 52 of the navigation system 100 is 08:45 am and the traffic accident occurred at the specific point P 51 It is anticipated that the congestion or delay due to the traffic accident will be solved until the expected arrival time of the congestion or delay due to the traffic accident is 08:35 in the morning, It is possible to continuously perform route guidance along the first route 10 without rediscovering the route to the destination.

If the travel route to the destination is rediscovered in accordance with the route search condition at the time of setting the first route 10, the control unit 170 determines whether the travel route It is possible to determine again whether or not a second path satisfying the setting criterion of the first path setting exists in step S170. If there is a second path matching the setting criterion in the first path setting, It is possible to perform the route guidance using the route that best matches the setting criteria of the first route as the second route [S180].

Hereinafter, it is assumed that the recommended route 1 (L1) and the recommended route 2 (L2) have been searched as a result of performing step S160.

According to the recommendation route 1 (L1), the distance to the destination is '13.2 km ', the estimated arrival time is '08: 50', the cost is '2,000 won' The distance to the destination is 13 km and the expected arrival time is 09:10 according to the first route 10. The distance to the destination is 14 km and the expected arrival time is 09:00 and the cost is 0 yen. , And the cost is assumed to be '0 won'.

For example, when the control unit 170 sets the 'distance priority' condition as the path search condition at the time of setting the first path 10, the first path 10 corresponds to the shortest distance , Since the second route matching the setting reference at the time of setting the first route does not exist, the first route can be maintained and the route guidance can be performed.

Also, for example, the controller 170 may control the first path 10 and the first and second paths 10 and 10 in consideration of a scheduled arrival time, regardless of the path search condition at the time of setting the first path 10, It is possible to determine a route to perform route guidance among the second recommended routes L1 and L2.

In this example, the control unit 170 transmits the recommended route 1 (L1) having the earliest expected arrival time out of the first and second recommended routes L1 and L2 and the first route 10 to the second Route guidance can be performed by using the route.

Also, for example, the controller 170 may determine a route to perform the route guidance considering the route search condition and the estimated arrival time at the time of setting the first route 10.

In this example, the controller 180 must maintain the first path 10 according to the path search condition at the time of setting the first path 10.

However, if the distance between the first path 10 and the first recommended path L1 is 200 meters and is included within a predetermined distance reference (for example, 1.0 km) If the difference in the estimated arrival time of the first recommended route L1 is 20 minutes longer than a predetermined time reference (for example, 15 minutes), the control unit 180 selects the first recommended route L1 The route guidance may be performed to the destination on the basis of the first recommended route L1.

14 (a), when the control unit 170 sets the 'free road' as the path search condition at the time of setting the first path 10, It is possible to display on the display module 141 a separate user interface 60 including information on the recommended route 2 (L2) and the remaining distance to the destination by the first route 10, have.

The user can select whether to redirect a route to the destination by using a route through the user interface 60 as a second route.
