The traffic information providing apparatus 300 generates traffic information by processing the above-described vehicle information based on the location information collected from the GPS satellites 200.

Here, the traffic information is distinguished from the vehicle information in that the traffic information is general information about the traffic situation at the node or link, not information about individual vehicles. For example, since the engine speed of a specific vehicle is information about an individual vehicle, it may be regarded as vehicle information, but information about traffic volume of a vehicle passing through a specific node or congestion state of a specific section (link) This is traffic information because it is not about the information but about the overall traffic situation.

On the other hand, a node is a place where a speed change occurs when a vehicle travels on a road. The types of nodes include intersections, bridge starting points, overpass starting points, road starting points, underground road starting points, and tunnel starting points. Points, administrative boundaries, IC / JC, and the like.

In addition, the link means a line connecting the node and the node, and may include a road, a bridge, an overpass, an underground driveway, a tunnel, and the like.

Since the traffic information is not information about individual vehicles, it is processed and generated only when the location information such as node location or link location is accompanied by vehicle information. More specifically, when vehicle information or location information about a vehicle other than its own vehicle is added, it is reprocessed into more reliable and useful traffic information.

Therefore, when the traffic information providing apparatus 300 generates the traffic information by processing the vehicle information received from the OBD connector 100 based on the location information received from the GPS satellite 200, the generated traffic information is the traffic information center. Reprocessed from the integrated server 400 of the vehicle is transmitted to the traffic information providing device 300 is provided to the user.

The traffic information processed by the traffic information providing apparatus 300 is reprocessed by the integrated server 400 of the traffic information center because the vehicle information and the location information for the other vehicles described above are necessary, but the traffic information is provided. There is also a reason that the computing power or processing power is limited due to the terminal characteristics of the device 300.

That is, the traffic information providing apparatus 300 receives vehicle information and position information of another vehicle from the integrated server 400 of the traffic information center, and does not reprocess traffic information by itself, and has an integrated server having excellent computing power or processing ability ( In step 400, the traffic information reprocessed is received and provided on the screen.

Of course, this is merely an example for convenience of description, and the traffic information providing apparatus 300 receives external traffic information from the integrated server 400 or the traffic information providing apparatus of another vehicle using a communication network, based on this. In the case of reprocessing the traffic information processed directly it will be seen that it is within the technical scope of the present invention.

The traffic information providing apparatus 300 may be implemented to be integrated with some or all of various electronic devices used in a vehicle such as a black box, a navigation, a high pass, and the like. A detailed configuration of the traffic information providing apparatus 300 will be described later with reference to FIG. 3.

The integrated server 400 is used for the purpose of collecting and reprocessing the first processed traffic information from each vehicle and may be provided in a traffic information center for providing such a service.

In particular, the integration server 400 receives and stores node information and link information according to a standard node link scheme and traffic information received from each vehicle.

That is, the integrated server 400 does not create a separate unit node for the traffic information providing apparatus 300 to extract the node information and link information, for this purpose, according to the standard node link scheme stored in the integrated server 400 Vehicle information is processed by the traffic information providing apparatus 300 based on the node ID and the link ID.

In addition to reprocessing the traffic information, the integrated server 400 may collectively manage and process vehicle driving information such as member management, vehicle management, service management, information analysis, and information processing based on information received from the traffic information providing apparatus 300. Used to play a role.

Of course, the traffic information center may be an insurance company / maintenance server for providing insurance management, vehicle diagnosis, vehicle maintenance, etc. as a supplementary service, a gas company server for providing fueling information management, point management, billing management, certification management, It will be possible to build and provide a separate service provider infrastructure server to provide a. The configuration and role of these servers are also merely exemplary for convenience of description, and the number, types, numbers, uses, etc. of servers may be implemented differently from those described above.

Based on this, traffic information is generated by processing the vehicle information such that at least one of the speed, carbon emission amount, and driving information of the vehicle is generated as the traffic information in a predetermined unit node section.

For example, if it is determined that the current vehicle position is the first node and the current vehicle speed is determined to be 100 km / h based on the received vehicle information, the controller 330 determines that the traffic state of the first node is based only on this information. It will generate the first traffic information that is smooth or the average speed of vehicles is 100km / h.

Of course, since the traffic information is traffic information generated based on only one vehicle on which the traffic information providing apparatus 300 is mounted, the traffic information cannot be regarded as section traffic information indicating an overall traffic condition for a road section.

Therefore, the control unit 330 is to transmit the traffic information generated primarily to the integration server 400, to collect the traffic information of the other vehicles in the integration server 400 to receive the reprocessed traffic information to be provided to the user do.

The storage unit 340 stores the vehicle information received from the vehicle information receiver 310 and the location information received from the location information receiver 320. In addition, the storage unit 340 stores the node information and the link information, so that the control unit 330 can extract the node information and link information based on the position information received from the position information receiver 320.

Of course, the node information and link information may be implemented to be stored only in the integrated server 400, not stored in the storage unit 340, in this case, the control unit 330 is a position signal received from the GPS satellite 200 communication unit It may be implemented to be delivered to the integration server 400 through the 350, and provide the node information and link information to the vehicle information receiver 310 based on the location signal in the integration server 400.

The communicator 350 transmits the traffic information generated by the controller 330 to the integrated server 400, and is used for transferring the reprocessed traffic information received from the integrated server 400 to the controller 330.

The display 360 displays the traffic information reprocessed by the integrated server 400 on the screen to be provided to the user under the control of the controller 330.
