2 is a flow chart of a navigation path simulation method according to an embodiment of the invention. Referring to FIG. 2 , the method of the present embodiment is applied to the navigation device 100 of FIG. 1 . Hereinafter, the detailed steps of the navigation path simulation method are described in conjunction with the components in the navigation device 100 . First, the navigation device 100 is planned by the processing unit 140 . The navigation path is displayed on the electronic map (step S202). The navigation device 100 displays the electronic map in the form of a two-dimensional plan view or a three-dimensional bird's-eye view, for example, and marks the navigation path on the electronic map.

In detail, the navigation device 100 detects the location of the navigation device 100, for example, and receives the start and end positions by the input unit 130, and the processing unit 140 plans the navigation according to the positions of the start and end points received by the input unit 130. path.

It should be noted that in the case where the starting point and the ending point of the navigation path are far apart, the navigation device 100 needs to limit the display ratio of the map to display the details of the map. Therefore, when the navigation device 100 displays the navigation path, only the navigation path around the current location (for example, the location of the navigation device 100) can be displayed.

Next, the processing unit 140 enters a path simulation mode (step S204). The processing unit 140 starts the path simulation mode, for example, after the input unit 130 receives the operation action of the user, and the operation action may be a user pressing operation on the physical button on the input unit 130, or may be targeted by the user.

The above steps S506 to S512 are the same as or similar to the steps S204 to S210 of the foregoing embodiment, and thus the details thereof are not described herein again.

It should be noted that, in this embodiment, when the navigation icon moves to the congestion path in the navigation path, the processing unit 140 moves the navigation icon on the electronic map at the third speed (step S514), the third speed. Also less than the first speed. In detail, the third speed may be a fixed value, which may be the same as the second speed, and may be used to alert the user to the road condition. In addition, the third speed may also be a variable value that is proportional to the average speed of the congestion path. That is, the slower the average speed, the slower the third speed of the navigation icon movement; the faster the average speed, the faster the third speed of the navigation icon moves.

For example, FIG. 6 is an example of a navigation path simulation according to an embodiment of the invention. Referring to FIG. 6, the navigation map 600 displays the navigation path 610 and displays a navigation icon 620 on the navigation path 610 to represent the current simulated location. The navigation path 610 of the embodiment may also be divided into a straight path 612a, 612b, a turning path 614, and a congestion path 616. The congestion path 616 is represented, for example, by the depth of the color. The darker the color, the slower the vehicle speed, and the lighter the color, the faster the vehicle speed. When the navigational icon 620 is on the congestion path 616, the navigation device moves the navigational icon 620 at a relatively slower speed.
