First, the map matching unit 404 generates first position data and / or second position data based on respective signals received by the GPS receiver 401 and / or the DR sensor 402, And generates the current estimated position based on the first position data and / or the second position data. Thereafter, the map data corresponding to the traveling route is read out from the storage unit 405. In addition, although the location-based technology mainly uses GPS information, which is a signal received by the GPS receiver 401, in addition to the GPS information, cell tower signal triangulation and Wi-Fi location information Positioning Information (Hybrid Positioning System).

The map matching unit 404 matches the estimated position with the link (road) included in the map data, and outputs the matched map information (map matching result) to the control unit 408. For example, the map matching unit 404 generates an estimated position based on the first position data and / or the second position data, and outputs the estimated position and the map stored in the storage unit 405 And outputs the matched map information (map matching result) to the control unit 408.

At this time, the matched map information (map matching result) may include at least one of a traffic state (or a traffic flow state) for each road using preset user information, TPEG (Transport Protocol Exper Group) , Tire pressure condition, etc.), and the like. Here, the TPEG information is information transmitted from an external information providing center or a call center connected through the communication unit 409.

The control unit 408 then generates route guidance information based on the matched map information and outputs the generated route guidance information to the display unit 406 and the voice output unit 407. [ Here, the display unit 406 and the audio output unit 407 may be constituted by one device, for example, an output unit (not shown). The generated route guidance information may include at least one of map data, POI information, lane information, traveling speed limit information, and turn-by-turn list information.

5A, the control unit 408 displays the guidance information 510 corresponding to the current position 501 of the navigation device 400 on the display unit 406 (S110 ).

The communication unit 409 receives information including traffic information and the like transmitted from an arbitrary network service system communicatively connected under the control of the controller 408. [ Here, the network service system may include a social network service system or a server. At this time, the received information may be in a text format. In addition, when the new information is updated in the network service system, the communication unit 409 can receive the updated new information transmitted from the network service system in real time.

For example, the communication unit 409 may store the address information (e.g., "http://twitter.com/HappyTraffic," which is an address included in a specific social network service) stored in the storage unit 405 (Including a Twitter, a specific website, and the like) corresponding to the pre-stored address information under the control of the controller 408, and includes traffic information transmitted from the connected network service system Information (S120).

The control unit 408 then determines the current position information of the navigation device 400 based on the respective signals received in real time by the GPS receiver 401 and / or the DR sensor 402, Compares the traffic information included in the information and determines whether or not there is information corresponding to the current position information of the navigation device 400 among the received information.

For example, the traffic information included in the received information includes information of "(Teheranro) Samsung station → Gangnam station part 26 km / h lane (Olympic road) Banpo bridge ↔ Cheongdam bridge bilateral 20 km / h lane" If the current location of the navigation device 400 is "Yeoksam station ", the controller 408 confirms whether contents included in the traffic information and the current location of the navigation device 400 correspond to each other (S130).

If it is determined that there is information corresponding to the current position information of the navigation device 400 among the received information, the controller 408 determines whether the current position information of the navigation device 400 is included in the received information Extracts the corresponding information, and outputs the extracted information through the display unit 406 and / or the audio output unit 407.

When the extracted information is displayed on the display unit 406, the control unit 408 can display the navigation information displayed on the display unit 406 and the extracted information in cooperation with each other.

For example, the current location information (the location information) of the navigation device 400 among the received information ("(Teheranro) Samsung Station → Gangnam Station partial section 26 Km / 5B, the control unit 408 displays the received information in a pop-up form on the route guidance information 510 displayed on the display unit 406, ("(Teheranro) Samam station → Gangnam station partial section 26 km / h delay") 520 corresponding to the current position of the navigation device 400 can be displayed.

The control unit 408 character-recognizes the contents (text form) of the received information, matches contents corresponding to the route information among the character recognized contents to the map data, If the path information of the matched map data and the position information of the navigation device 400 overlap with each other, the control unit 408 determines whether the position information of the navigation device 400 is overlapped with the path information of the navigation device 400, The information corresponding to the position information of the navigation device 400 may be extracted from the received information and the extracted information may be outputted through the display unit 406 and / or the audio output unit 407 (S140) .

In the above embodiment, the navigation device 400 receives information transmitted from a specific network service system connected to the navigation device 400, and outputs corresponding traffic information based on the received information and the current position information of the navigation device 400 However, it is possible to check the current position of the specific navigation device 400 previously stored in the specific network service system in real time, and to check the current position of the specific navigation device 400 among the information including the traffic information Only the corresponding traffic information is transmitted to the navigation device, the specific navigation device 400 receives the transmitted traffic information (traffic information corresponding to the current position of the navigation device 400), and transmits the received traffic information Output. That is, the navigation device 400 may be configured to receive only information corresponding to the current position of the navigation device 400 from a large amount of information included in the network service system.

6 is a flowchart illustrating a navigation method according to a second embodiment of the present invention.

The control unit 408 controls the display unit 406 and / or the audio output unit 406 to transmit the set route information when the route (route guidance information) from the current position to the destination is set by the user 407 (S210).

Then, the communication unit 409 receives information including traffic information and the like transmitted from an arbitrary network service system communicatively connected under the control of the control unit 408. [ Here, the network service system may include a social network service system, a server, or the like. At this time, the received information may be in a text format. In addition, when the new information is updated in the network service system, the communication unit 409 can receive the updated new information transmitted from the network service system in real time.

For example, the communication unit 409 may store the address information (e.g., "http://twitter.com/HappyTraffic" included in the specific social network service) stored in the storage unit 405 (Including a Twitter, a specific website, and the like) corresponding to the previously stored address information under the control of the control unit 408, and transmits information including traffic information and the like transmitted from the connected network service system (S220).

Thereafter, the controller 408 compares the traffic information included in the received information with the set route information, and determines whether there is information corresponding to the set route information among the received information.

For example, the traffic information included in the received information includes information of "(Teheranro) Samsung station → Gangnam station partly 26km / h lane (Olympic road) Banpo bridge ↔ Cheongdam bridge bilateral 20km / h lane" If the information includes the information of " Yeoksam station → Gangnam station → Kyebada station → Seocho station, the control unit 408 determines whether the contents included in the traffic information and the contents included in the set route information correspond to each other (S230).

If it is determined that there is information corresponding to the set route information among the received information, the controller 408 extracts information corresponding to the set route information from the received information, Through the display unit 406 and / or the audio output unit 407.

When the extracted information is displayed on the display unit 406, the control unit 408 can display the navigation information displayed on the display unit 406 and the extracted information in cooperation with each other.

For example, if the received information ("Yeoksam Station → Gangnam Station → Gyeongbada Station → Gangnam Station → Gangbuk Station → Yeongam Station → Yeongam Station → Yeongam Station → Yeongam Station → Yeongam Station → Yeonnam Station The control unit 408 displays the content corresponding to the set route information among the received information in a pop-up form on the route guidance information displayed on the display unit 406 (" (Teheran Road) Samsung Station → Gangnam Station section 26km / h delay ") can be displayed.

The control unit 408 character-recognizes the contents (text form) of the received information, matches contents corresponding to the route information among the character recognized contents to the map data, The control unit 408 determines whether there is a route overlapping the path information of the matched map data and the set route information if the route information is overlapped with the set route information, Information corresponding to the information may be extracted and the extracted information may be output through the display unit 406 and / or the audio output unit 407 (S240).

Thereafter, the controller 408 parses the corresponding content (S250), and determines whether the speed-related information (speed information) among the parsed contents is smaller than a predetermined value.

For example, the control unit 408 parses the corresponding content ("(Teheranlo) Samsung station → Gangnam station partly 26 Km / h zone") and analyzes the parsed contents (road name (Teheranro) 26Km / h "among speed information (26Km / h), speed information (26Km / h), traffic information For example, 30 Km / h) (S260).

If the speed information is smaller than the preset value, the control unit 408 resets the set path information (or path information) based on information (path information) related to the path among the parsed contents, And outputs the reconfigured route information through the display unit 406 and / or the voice output unit 407.

For example, when the confirmed speed information (26 Km / h) is smaller than the preset value (for example, 30 Km / h), the controller 408 transmits the set route information (Yeoksam Station -> Gangnam Station -> (Yeoksam Station → Yangjae Station → Seocho Station) that bypasses the path information of the parsed contents (Samseong Station → Gangnam Station) from the display unit 406 and / or the audio output unit 407 in step S270.

In the above embodiment, when the speed information is less than a predetermined value among the parsed information of the received information, the control unit 450 describes the resetting of the set route information, (For example, " congestion ") among the parsed information and whether or not the traffic situation information (including smoothness, lag and congestion) is a predetermined value , And reset the set route information.

7 is a signal flow diagram illustrating a communication process of the navigation system according to the third embodiment of the present invention.

Also, the server 500 may automatically check the communication connection state of the navigation device 400, the position information of the navigation device 400, and the like in real time (SP310).

Thereafter, the server 500 determines whether information corresponding to the position information of the navigation device 400 is included in the information including the traffic information transmitted from the network service system 600 (SP320).

If it is determined that there is information corresponding to the location information of the navigation device 400 among the information including the traffic information, the server 500 determines whether the current location information of the navigation device 400 And extracts information corresponding to the information.

For example, the current location information ("Yeoksam station") of the navigation device 400 among the above information ("(Teheranro) Samsung station → Gangnam station partial section 26 Km / h lane (Olympic road) Banpo bridge ↔ Cheongdam bridge double lane 20 Km / h lane" , The server 500 transmits information ("(Teheranro Samse station → Gangnam station partial section 26 km / h)" corresponding to the current position information of the navigation device 400 from the information (SP330).

Thereafter, the server 500 transmits the extracted corresponding information to the navigation device 400 (SP340).
