For example, as shown in FIG. 3, when the route of the guide vehicle for the B vehicle to be forwarded is displayed and then the route of the guide vehicle for the A vehicle is input from the A vehicle, Of the guide vehicle. Accordingly, when the route of the guide vehicle is overlapped in this manner, a warning can be output to recognize the danger.

In addition, when the route of the guide vehicle with respect to the C vehicle to which the driver wishes to make a right turn is displayed, the route may overlap with the route of the guide vehicle with respect to the B vehicle.

On the other hand, the control unit 50 may generate the route of the guide vehicle, and then transmit the route of the guide vehicle to the nearby vehicle through the vehicle communication unit 70 so that the route of the guide vehicle may be compared to warn the neighboring vehicle.

As described above, according to the navigation device according to the embodiment of the present invention, when the route of the guide vehicle is displayed on the basis of the searched travel route, the vehicle information is input from the shot image and the surrounding vehicle It is possible to not only notify a driver of a collision prediction situation overlapping with the route of the guide vehicle in advance, or generate a guidance route by guiding the route, thereby guiding the safe route, as well as promoting safe driving.

4 is a flowchart illustrating a route guidance method of a navigation device according to an embodiment of the present invention.

4, in the route guidance method of the navigation device according to the embodiment of the present invention, the control unit 50 receives the GPS signal from the GPS receiving unit 10 and grasps the position of the vehicle (S10 ).

The control unit 50 receives the GPS signal and determines the position of the vehicle. Then, the control unit 50 searches the map data storage unit 40 for the travel route in accordance with the destination and operation command from the key input unit 10.

The control unit 50 receives the photographed image photographed through a plurality of forward cameras (not shown) from the image input unit 30 and analyzes the lane information from the photographed image (S20).

At this time, the control unit 50 may analyze the vehicle information including the position and the speed for the forward vehicle from the photographed image for the augmented reality.

Thereafter, the control unit 50 generates a route of the guide vehicle for displaying on the basis of the searched traveling route, and displays the route through the display unit 60 (S30).

In the present embodiment, the route of the guide vehicle is a route along with the guide vehicle, which is a virtual vehicle image, with the predicted route that the vehicle can travel along the travel route.

After generating the route of the guide vehicle, the route of the guide vehicle can be displayed on the front window of the vehicle through the head-up display based on the augmented reality.

Thereafter, the control unit 50 receives the vehicle information of the nearby vehicle from the vehicle communication unit 70 based on the location of the vehicle (S40).

At this time, if the route of the guide vehicle to the neighboring vehicle is inputted from the vehicle information of the neighboring vehicle, the control unit 50 compares the route of the guide vehicle with respect to the present vehicle and the route of the guide vehicle with respect to the neighboring vehicle, (S50).

On the other hand, when there is no route of the guide vehicle to the neighboring vehicle in the vehicle information of the neighboring vehicle, the position, speed, and direction of the neighboring vehicle are analyzed from the vehicle information of the neighboring vehicle, It can be compared to whether it overlaps with the path of.

In addition, when compared with the route of the guide vehicle, the control unit 50 analyzes the shot image input from the image input unit 30 and compares the captured image with the vehicle information of the preceding vehicle to determine whether the vehicle exists on the route of the guide vehicle. 1, if there is a preceding vehicle F on the route of the guide vehicle G, the control unit 50 generates a avoidance route of the guide vehicle, thereby providing a predictable route that avoids collision and travels .

Thereafter, the control unit 50 displays the comparison result obtained by comparing the route of the guide vehicle above with the vehicle information of the nearby vehicle and the vehicle information of the neighboring vehicle according to the comparison result through the display unit 60, .

For example, as shown in FIG. 3, when the C vehicle to be turned right is intended to travel on the route of the guide vehicle generated along the travel route, it overlaps with the route of the guide vehicle to the B vehicle traveling in the right lane When traveling along the route of the guide vehicle, collision may occur and a warning may be generated.

Accordingly, when the route of the guide vehicle is overlapped, the control unit 50 outputs the comparison result to the display unit 60 and outputs a warning via the warning unit 80 so as to recognize the danger S60).

On the other hand, the control unit 50 generates the route of the guide vehicle at step S30, and then transmits the route of the guide vehicle to the nearby vehicle based on the V2X communication technology through the vehicle communication unit 70 to compare the route of the guide vehicle So that a warning can be issued.

As described above, according to the route guidance method of the navigation apparatus according to the embodiment of the present invention, when the route of the guide vehicle is displayed on the basis of the detected travel route, The driver can be notified of the collision prediction situation that overlaps with the route of the guide vehicle by generating a warning signal or generating an avoidance route,
