2 is a block diagram of a car navigation system according to an embodiment of the present invention.

Referring to FIG. 2, the car navigation system includes a traffic information receiver 320, a GPS receiver 310, an engine unit 330, a communication unit 340, a cost information storage unit 350, and a map information storage unit 360. ), An input unit 370, a display unit 380, a recommended route storage unit 390, and a driving log storage unit 391.

The traffic information receiving unit 320 receives traffic information from a server (not shown) that provides external traffic information, and the traffic information may include a timely congestion situation of a vehicle. The GPS receiver 310 receives signals from a plurality of GPS satellites and calculates and outputs its position. The cost information storage unit 350 stores time information for each link in the path from the starting point to the destination, and also stores time information for passing through various links. Such time information may be updated with reference to traffic information. The communication unit 340 performs wireless communication through the network 500 such as WIBRO or WIMAX, or the mobile phone 100 or the computer 400 using one of Bluetooth, USB, WIFI, ZIGBEE, BINARY CDMA, and UWB. For example, the electronic device may communicate with the route recommendation system 600 through a predetermined device capable of internet.

The map information storage unit 360 stores a national map or predetermined corresponding local map information. The input unit 370 may receive a user's selection to provide a corresponding service, and may be selected as necessary. The display unit 380 displays information under the control of the engine unit.

The driving log storage 391 stores a path that the vehicle travels from the starting point to the destination, which may be an optimal path or other path guided by the engine unit 330. In practice, the best and recommended paths can be the same or different. The recommended path storage unit 390 stores the recommended path, which may be updated.

The engine unit 330 receives a recommendation path through the communication unit 340, stores the recommendation path in the recommendation path storage unit 390, and provides the recommendation path when guiding the recommendation path.

The engine unit 330 includes a path controller 331 and a driving log controller 332. The path controller 331 guides the recommended path or the optimal path according to the user's selection, and may provide only one path as needed. The driving log control unit 332 determines the current position from the output of the GPS receiver 320, extracts the driving log of the vehicle, and transmits the driving log to the route recommendation system 600 through the communication unit 340. The recommendation route input through the system is stored in the recommendation route storage unit. In this case, the operation log may be transmitted in real time, after a predetermined time interval or after the operation is completed, and may be transmitted at various times as necessary. In addition, the driving log control unit 332 stores the driving log information in the driving log storage 391, and the driving log information may be stored in real time or at predetermined time intervals.

Next, a route recommendation method according to an embodiment of the present invention will be described in detail.

First, the user manipulates the input unit 370 to input a destination (S310), and accordingly, the route controller 331 refers to the cost information of the cost information storage unit 350 and the map of the map information storage unit 360. The optimum route, which is the shortest time path from the current position to the destination, is calculated, the GPS receiver 310 receives the current position, displays the current position on the display unit, and starts the route guidance (S320). This route guidance process is well known in the art and thus a detailed description thereof will be omitted.

At this time, the driving log control unit 332 stores the route in which the vehicle actually travels along the route guided by the route control unit in the driving log storage unit 391. The driving log may be generated by storing GPS information in real time or may be generated by other methods. In some cases, the driver may set his own driving route differently from the route guidance. For example, although the highway is blocked, the route guidance is a national road, but even if the driver is blocked, the highway may be convenient because the highway is convenient, and a wide new road is recommended for the route guidance, but the driver may operate a scenic old road.

In addition, the driving log control unit 332 wirelessly transmits driving log information, which is a path in which the vehicle actually travels, to the network network 500 through the communication unit 340 according to the route guided by the route control unit, to the network network 500. The connected server 610 receives the driving log information (S330).

Next, the information receiving unit 613 of the server 610 stores the driving log information received from the plurality of car navigation systems in the reception information storage unit 622, respectively (S340). At this time, if necessary, the authentication process may be added with reference to the member database 623. In addition, the recommendation information providing unit 611 generates the most used route as a recommendation route from the operation log records stored in the reception information database 622 according to a real time or a predetermined period as a recommendation route. Is transmitted to the car navigation system 300, and is also stored in the recommendation information database 621 (S360).

Thereafter, the driving log controller 332 receives the recommended route through the communication unit 340 and stores the recommended route in the recommended route storage unit 390 (S350).

Then, when the route is guided in the state in which the recommendation route is stored, the recommendation route is additionally provided if there is a recommendation route at the destination at the current location according to the user's selection (S370). That is, it provides an optimal route or recommended route which is the shortest time route to the destination.

Meanwhile, even when the communication unit 340 does not have a wireless Internet function, the driving log information is connected to a mobile phone or a computer having an Internet function through one of Bluetooth, USB, WIFI, ZIGBEE, BINARY CDMA, and UWB. May be sent to the route recommendation system and the recommendation route may be received.

In this case, the communication unit 340 is interworked with a mobile phone or a computer having an Internet function through one of Bluetooth, USB, WIFI, ZIGBEE, BINARY CDMA, and UWB.

An example of a dual mobile phone is as follows.
