Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation display device, and more particularly to a navigation display device for guiding a route at a branch point of a road.

[0002]

2. Description of the Related Art A conventional navigation display device guides route guidance by displaying the current position of the vehicle on a map of various scales on a display screen.

When performing route guidance at a branch point of a road such as an intersection, for example, the route to be shown on the map displayed on the display screen is indicated by arrows or colored to guide the driver. .

[0004]

However, when a detailed map with a small scale is displayed on the screen, the branch shape of the road is clear, but it is not possible to know which direction each branch road is heading toward. , When a large-scale map with a large scale is displayed on the screen, it is easy to understand which direction each branch road is heading, but it is difficult to understand the branch shape of the road, and the map scale can be switched many times during driving. It is difficult to operate the remote control while driving,
There was a problem that driving was extremely dangerous.

The present invention has been made in order to solve the above-mentioned problems, and even if the vehicle approaches a branch point during operation, the safety is ensured without switching the map screen and the destination is reached. The purpose is to enable the driver to drive without hesitation.

[0006]

A navigation display device according to claim 1 of the present invention is a navigation display device for displaying a map and the current position of the vehicle on a screen, and displays the route to a branch point of the road of the vehicle. Detecting means for detecting the approach, and when the detecting means detects the approach to the branch point of the road, the shape of the branch path at the branch point and the information about the branch path are displayed on a part of the screen at an appropriate scale. The display means is provided.

A navigation display device according to a second aspect of the present invention is the navigation display device according to the first aspect, wherein the information about the branch road includes a name of a reaching point of the branch road and a distance to the reaching point.

[0008]

In the navigation display device according to claim 1 of the present invention, the navigation display device displays the map and the current position of the host vehicle on the screen, and the approach of the host vehicle to the branch point of the road is detected, When the approach to the branch point of the road is detected, the shape of the branch road at the branch point and the information about the branch road are displayed on a part of the screen at an appropriate scale, so the scale of the map on the screen does not need to be changed. Even so, the shape of the fork and the information about the fork will be clarified, and it will be an effective clue for route guidance to the destination.

In the navigation display device according to claim 2 of the present invention, in the navigation display device according to claim 1, since the information about the branch road includes the name of the reaching point of the branch road and the distance to the reaching point, By referring to the name of the arrival point on the road, it is possible to travel while maintaining a distance to the destination.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a navigation display device according to the present invention will be described below with reference to the drawings.

FIG. 1 is a display screen view showing a guide map of a branch on the display screen of the navigation display device of the present invention.

In FIG. 1, the display screen of the navigation display device includes the present position 1 of the vehicle, a branch point 3, and a branch point guide map 5 at the branch point 3 in the displayed map screen of a certain scale. .

Branch point guidance FIG. 5 further shows a branch point name field 7
And a branch point display diagram 9. Here, the branch point includes an intersection.

When the current position 1 of the host vehicle approaches the branch point 3 indicated by a star while traveling, the current position 1 or the branch point 3 of the host vehicle on the screen is displayed regardless of the scale of the map displayed at that time. The branching point guidance map 5 is displayed at a position where it does not obstruct route guidance so that, for example, is not hidden. In FIG. 1, the branch road guide map 5 is displayed in a field from the branch point 3. The size of the branch point guide map 5 is appropriately about 1/9 of the entire screen of the navigation display device, but the size is not limited to this.

As a standard for approaching to the branch point 3, for example, about 500 meters before the branch point 3 is suitable.

Branching Point Guide In the branching point name field 7 of FIG. 5, the names of branching points (intersections) determined by the police are displayed. Branching point display FIG. 9 shows a branching path shape diagram of a branching point 3 at a scale of an easy-to-see scale (for example, a scale of about 1/500). The distance is displayed. In FIG. 1, as a specific example, the name of a branch road (intersection) called “Honmachi Ichi” is displayed in the branch name field 7, and the branch point display diagram 9 shows the branch shape diagram of each branch road from the branch point 3. The name of the reaching point and the distance to the reaching point are "To Osaka 20 km", "To Ikaruga 3 km", "To Nara 10 km", and "To Yamato Takada".
5 km "is displayed.

The branch point guide map 5 is automatically deleted when the branch point is passed. Actually, the branch point guide map 7 is displayed only at the main branch points.

According to the navigation display device as described above, the shape of the branch road and the information about the branch road are clarified every time when the vehicle passes through the branch point without changing the scale of the map on the screen. It is an effective clue for route guidance. When the information about the branch road is the name of the arrival point of the branch road and the distance to the arrival point, it is possible to travel while having a sense of distance to the destination by referring to the name of the arrival point of the branch road.

Therefore, even if the vehicle approaches a branch point during driving, it is not necessary to switch the map screen, so safety is ensured and the driver can travel to the destination without hesitation.

[0020]

As described above, according to the present invention, claim 1
In the navigation display device, the map and the current position of the host vehicle are displayed on the screen, the approach of the host vehicle to the road branch point is detected, and when the approach to the road branch point is detected, the branch point is detected. Since the shape of the branch road and the information about the branch road are displayed on a part of the screen at an appropriate scale, the shape of the branch road and the information about the branch road can be clarified without switching the scale of the map on the screen. It becomes an effective clue for route guidance to the destination.

In the navigation display device according to a second aspect, in the navigation device according to the first aspect, since the information regarding the branch road includes the name of the arrival point of the branch road and the distance to the arrival point, the arrival point of the branch road is reached. It is possible to drive while having a sense of distance to the destination by referring to the name.

As a result, even if the vehicle approaches a branch point during driving, it is not necessary to switch the map screen, so that safety is ensured and the driver can travel to the destination without hesitation.
