5 is a flowchart illustrating a vehicle navigation method according to the first embodiment of the present invention.

First, the control unit 407 forms a wireless network with the terminal (s) (e.g., the vehicle navigation device) mounted on at least one or more peripheral vehicles (s) through the communication unit 408 (S11). The communication unit 408 may form a wireless network with a terminal installed in a neighboring vehicle through a Bluetooth communication network or may form a wireless network with a terminal installed in a neighboring vehicle through various wireless communication networks.

The communication unit 408 receives the first travel route information (first travel route) of the specific vehicle from a terminal (for example, a vehicle navigation device) mounted on a nearby vehicle (for example, a specific vehicle) And outputs the first traveling route information to the controller 407 (S12). The first travel route information of the specific vehicle may be a travel route including a departure point, a stopover route, and a destination.

The control unit 407 compares the received first travel route information (first travel route) with the second travel route information (second travel route) of the current vehicle to compare the first travel route and the second travel route It is determined whether the paths coincide with each other (S13). For example, the control unit 407 reads (reads) the second travel route of the current vehicle from the storage unit 404, compares the read second travel route with the received first travel route, It is determined whether or not the first travel route matches the second travel route of the current vehicle. The interval in which the first travel route and the second travel route coincide with each other is an interval from the departure point to the destination of the first and second travel routes or a predetermined interval (or a preset distance) (for example, To 1 Km in the forward direction).

The controller 407 determines whether the first travel route is the opposite direction to the second travel route (S14). For example, the control unit 407 determines that the traveling direction of the first traveling route is the same as the traveling direction of the current vehicle based on the first traveling route information in order to exclude unnecessary traffic information and receive only efficient traffic information It is determined whether the vehicle is traveling in the opposite direction. Here, the step of determining whether the first travel route is in the opposite direction to the second travel route may be omitted or added. Further, the peripheral vehicle (for example, the specific vehicle) may be a forward vehicle that travels in the same direction.

When the first travel route matches the second travel route of the current vehicle and the first travel route is in the opposite direction to the second travel route (S15), traffic information corresponding to the first travel route is received from the terminal mounted on the specific vehicle (neighboring vehicle) through the communication unit 408. [

The control unit 407 adds the traffic information corresponding to the received first travel route to the traffic information corresponding to the second travel route (S16), and adds the added traffic information to the output unit (e.g., (Eg, road blockage, accident / construction, etc.) by outputting the voice and / or image through the voice output unit 405 and / or the voice output unit 406 (S17).

Here, the control unit 407 releases the wireless network with the C vehicle because the traveling route information of the C vehicle does not match the traveling route information of the current vehicle A.

Then, the control unit 407 determines whether the driving route of the B vehicle is the opposite direction (reverse direction) to the traveling route of the current vehicle, and determines whether the traveling route of the B vehicle is the traveling route of the current vehicle A And receives the traffic information corresponding to the traveling route from the vehicle navigation device of the B vehicle when the vehicle is in the opposite direction.
