The input unit 120 is a component for inputting departure information or destination information. In some cases, it may be for inputting waypoint information.

The controller 130 generates route information according to the current location information (or starting point information) and the destination information, and arranges and displays the direction instructions according to the route information on the screen in the order of progress. Here, the direction instruction may be TBT (Turn By Turn) information including a right turn instruction, a left turn instruction, a U-turn instruction, a piton instruction, a cuton instruction, and the like, but the present invention is not limited thereto. The direction indication includes the first direction indication, the next direction indication, and the next direction indication based on the current position. For example, 'turn left before 300m', 'turn left after 20m and then turn right' and 'turn right after 45m' are all displayed on the screen. Each direction instruction may be represented by an arrow image, and the map image according to the current location information may be further displayed together with the direction instruction.

The memory 140 is a component in which map information including a map image is stored, and the display unit 150 is a display device on which a screen configured by the controller 130 is displayed.

2 is a view showing a sequence of a navigation method according to an embodiment of the present invention. Referring to the drawing, first, a user inputs destination information to go to and inputs a directions command (step S110). In some cases, it is possible to input waypoint information. Then, the navigation system receives the current location information (step S120). Then, the route information is generated using the destination information (and waypoint information) input in step S110 and the current location information received in step S120 (step S130). When the route information is generated, regardless of the distance to the turn point, the direction indication according to the route information is arranged and displayed on the screen in the order of progress (step S140). 3 and 4 are examples of a screen configuration including a direction indication according to the present invention. Referring to FIG. 3, in the direction indication region D located at the bottom of the screen, the first direction instruction D1, the next direction instruction D2, and the next direction instruction D3 are arranged in the left to right direction in the order of progress. have. In this case, the direction indication is represented by the arrow image, and the remaining distance to the turn point (for example, 2.1 km) or the distance between the turn points (for example, 20 m and 300 m) are further displayed along with the direction indication. Referring to FIG. 4, in the direction indication region D on the left side of the screen, the first direction instruction D1, the next direction instruction D2, and the next direction instruction D3 are arranged from top to bottom in the order of progress.

For example, when the first direction indication D1 is normally performed, the next direction indication D2 moves to the first direction indication area D1, and the next direction indication value D3 is the next direction indication area D2. To go to.

7 is a diagram illustrating a procedure of a navigation method according to another embodiment of the present invention. The navigation method according to another embodiment of the present invention corresponds to a case where a user or a vehicle does not actually travel, but simulates driving by arbitrarily setting starting point information. Therefore, there is a difference from the navigation method according to the exemplary embodiment of the present invention described with reference to FIG. 2 in that it uses the source information input by the user without receiving the current location information.

Referring to FIG. 7, a user inputs destination information and departure information (steps S210 and S220). Then, the navigation system generates route information by using the destination information input in step S210 and the departure point information input in step S220 (step S230), and arranges and displays the direction instructions according to the route information on the screen in the order of progress. (Step S240). In this case, the map image may be displayed on the screen together with the direction indication (S250). If the user inputs a path summary command (step S260). All the directions from the first direction to the last direction is displayed on the screen (step S270). This process is repeated until the simulation driving ends (step S280).

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.

According to an aspect of the present invention, since the user may be provided with a guide on the direction indication (left turn, U-turn, etc.) in advance even before the user reaches the turn point, that is, before starting the driving or during the simulation driving, the user You can plan ahead.

According to another aspect of the present invention, when the user is driving, the user is traveling because three or more direction instructions (first direction instruction, next direction instruction, and next direction instruction) are provided at the same time based on the user's current position. In the meantime, you can be prepared for the turn.

According to another aspect of the present invention, confusion as to which direction instruction should be performed first, since three or more direction instructions including the first direction instruction are arranged from left to right or top to bottom in the order of progression. This is significantly reduced.
