Here, the second mapping image can be generated by calculating the vehicle traveling direction.

In the present invention, the current position information of the vehicle stored in the memory 100 is as follows, where longitude and latitude information (current location information of the vehicle acquired through GPS) is defined as (location longitude, location latitude).

(Position hardness T-n, position latitude T-n)

...

(Position hardness T-2, position latitude T-2)

(Position hardness T-1, position latitude T-1)

(Position hardness T, position latitude T)

The terminal 1 extracts the vehicle traveling direction from the vector (S805).

The terminal 1 adjusts the vehicle traveling direction when necessary (S806). Here, the meaning when necessary means that it is necessary to adjust the traveling direction of the vehicle. For example, if it is not necessary to adjust the traveling direction of the vehicle, the terminal 1 does not adjust the traveling direction of the vehicle.

The terminal 1 generates a second mapping page (S807). The terminal 1 can output the generated second mapping image as shown in FIG. 9 and display it.

The terminal 1 checks whether there is a change in the vehicle traveling direction (S808).

If there is a change in the vehicle traveling direction, the terminal 1 replaces the value of (position hardness T-1, position latitude T-1) with the value of position hardness T and position latitude T (S808) .

If there is no change in the vehicle traveling direction, the terminal 1 ends the second mapping image generation.

FIG. 10 is a flowchart illustrating a process of generating a display image according to an exemplary embodiment of the present invention, and FIG. 11 is a view illustrating a display image according to an exemplary embodiment of the present invention.

Here, since the vehicle always travels toward the front with respect to the driver, the second mapping image generated by adjusting the traveling direction of the vehicle (traveling path) is referred to as a second mapping image so that the front of the vehicle is at 12 o'clock So that a display image can be generated and displayed.

Referring to FIG. 10, the terminal 1 confirms the vehicle traveling direction angle (S1001).

The terminal 1 calculates the difference R between the north direction N and the vehicle traveling direction angle (S1002).

The terminal 1 confirms whether the difference R between the north direction and the vehicle traveling direction angle is positive (S1003).

If the difference R between the north direction and the vehicle traveling direction angle is positive, the terminal 1 rotates the second mapping image by R in the counterclockwise direction on the basis of the current position of the vehicle to generate a display image (S1004 ).

If the difference R between the north direction and the vehicle traveling direction angle is not positive, the terminal 1 rotates the second mapping image by R in the clockwise direction on the basis of the current position of the vehicle to generate a display image (S1005 ). Here, when the difference R between the north direction and the vehicle traveling direction angle is not (+), it means that the difference (R) between the north direction and the vehicle traveling direction angle is negative.
