Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a human-powered device for road map information that is applied to input road map information used in a vehicle route guidance device (navigation system).

<Prior Art> In a navigation system installed in a vehicle to provide route guidance, road map data is recorded on a CD-ROM, for example, and necessary road map data is read out at any time and displayed on a display device. In addition, by matching the vehicle position detected by the direction sensor or mileage sensor with road map data for route calculation, the accurate vehicle position is calculated and displayed on the road map.

When displaying a road map, it is better for driving to display as much information about the road as possible, for example, facilities near the road, so the above road map data includes information such as bridges, stations, buildings, road repair points, etc. It also contains a lot of facility information.

<Invention or problem to be solved> However, conventionally used road maps are generally created based on paper maps created based on aerial photographs. It was difficult to reflect information about facilities or facilities that had changed, making it difficult to prepare road maps that included the latest information.

Therefore, even if map creators (for example, navigation system software creators or engineers who maintain navigation systems) try to incorporate the latest information into road map data, the latest facilities cannot be found in commercially available detailed maps. Since the coordinates of the facility are often not listed, it is not easy to determine the coordinates of the facility, and in the end, the location of the destination facility is determined from the surrounding topography using memory or photos, and then marked on the map. I had no choice but to do it. For this reason, the work takes a lot of time and mistakes are likely to occur, resulting in a decrease in work efficiency.

Therefore, the present invention provides road map information that allows the creation of road map data that includes accurate and up-to-date facility information by allowing the passenger to input facility information that he or she selects while the vehicle is running. The purpose is to provide an input device.

<Means for Solving the Problems> The road map information input device of the present invention that achieves the above object includes a position detection means for detecting the current position of a vehicle;
road map data storage means storing road map data; map display means for displaying the road map acquired from the road map data storage means together with the current position of the vehicle detected by the position detection means; a cursor operating means capable of specifying a position; an information inputting means for inputting information on a point indicated by the cursor operating means; , and road map information writing means for writing into the road map data storage means.

<Operation> According to the road map information input device configured as described above, when a passenger riding in a vehicle identifies a specific facility (for example, the facility he/she is currently crossing) and wants to input that information into a road map, the user inputs that facility. The user carefully confirms the location of the facility, uses the cursor operation means to indicate the location of the facility, and inputs information about the indicated point using the information input means. Then, the road map information writing means writes that information into the road map data storage means together with the coordinates of the cursor position at the time when the information is input.

<Example> Embodiments will be described in detail below with reference to the accompanying drawings showing embodiments.

FIG. 1 is a block diagram showing an electrical configuration for implementing a road map information input device of the present invention.

This device uses a so-called navigation system 1 mounted on a moving vehicle to obtain road map data that includes accurate and appropriate facility information when the vehicle is moving.

The navigation system 1 includes a current position detection unit 1];
It has a map display section 12 and a map data storage section 13.

The current position detection unit 11 includes a vehicle speed sensor configured as a spatial filter, a direction sensor configured as an optical fiber gyro, and a map database configured as a CD-ROM that stores road map data for route calculation. A map matching process is performed based on the output of the above-mentioned sensor and road map data for route calculation stored in a map database for route calculation. By doing so, the current position of the vehicle is calculated.

Note that the current position detection unit 11 is not limited to the above configuration; for example, in addition to the above configuration, the current position detection unit 11
It may be equipped with an obal position system).

The map display unit 12 displays the current position of the vehicle detected by the current position detection unit 11 together with a road map.
It consists of such things as A cursor operation section 14 is attached to the map display section 12, and by performing a predetermined operation, the cross cursor can be positioned at any position on the display screen.

The map data storage unit 13 is a map database for screen display, which divides the road map into meshes, stores road network data consisting of a combination of nodes and links for each mesh, and also stores facilities around the road. remembers data. The above facility data includes data representing buildings, railways, rivers, etc., place name data, and the like.

A personal computer 2 is connected to such a navigation system 1. This personal computer 2 can obtain the mesh number of the map displayed on the map display section 12 and the coordinates of the position indicated by the cross cursor from the navigation system. Connected to this personal computer 2 are a keyboard 22 for inputting facility information, and an external storage device 23 such as a floppy disk unit. When the keyboard 22 is operated, a screen appears on the CRT 21 for inputting information such as the name of the facility selected with the cross cursor and the data number of that facility.

Hereinafter, a method for inputting facility information while the vehicle is running and creating road map data that includes accurate and appropriate information will be explained.

For example, assume that a map stored in the map data storage unit 13 is displayed in an enlarged manner as shown in FIG. 2, and a new building A is constructed in the vicinity. Of course, building A is not recorded in the map data storage section 13.

First, the passenger of the vehicle C operates the keyboard 22 of the personal computer 2 to call up a facility information manual screen as shown in FIG.

When the passenger is driving a car in a position where building A can be clearly seen, the passenger checks building A and, when he or she understands its position, operates the cross cursor operation unit 14 to move the cross cursor to the position of the building. .

Since the passenger is well aware of the location of the facility on the road map, he or she should be able to accurately operate the cursor to indicate the facility.

Then, while looking at the CRT 21 screen, press the keyboard 22.
Enter the center point and prefecture, and enter the necessary information such as notes. Of course, this manual effort may be performed before the cross cursor is placed, rather than after the cross cursor is placed.

The input information is written from the external storage device 23 to a floppy disk or the like along with the coordinates of the position where the cross cursor is placed. Therefore, the latest facility data including facility A is always stored on the floppy disk. If the contents of this floppy disk are transferred to the map data storage section 13 as appropriate, the map data storage section 13 will have the latest road map data.

As a result, it becomes possible to easily create an up-to-date and accurate map database that includes data on newly established facilities without relying on aerial photographs or the like.

Note that the present invention is not limited to the above-described embodiments. For example, in the above embodiment, the road map data is updated by inputting the newly established facility A, or even if the facility is already included in the road map data,
You can delete, reposition, or change the name at any time. Further, although the personal computer 2 is used in the above embodiment, an electronic notebook may be used instead. In this case, the keyboard 22 of the personal computer 2 can be used as a key fod of the electronic notebook, or as a CRT.
21 is replaced with a liquid crystal display of the electronic notebook, and the external storage device 23 is an IC card of the electronic notebook. Other various design changes may be made within the scope of not changing the gist of the invention.

<Effects of the Invention> As described above, according to the road map information input device of the present invention, the passenger uses the cursor operating means to indicate the facility he or she wishes to input, and uses the information manual means to input the name, etc. of the indicated point. When information is input, that information is written to the road map data storage means along with the coordinates of the cursor position at the time the information is input, so the latest and accurate road map data can be provided at any time, and the vehicle navigation system can can improve the usability of the application system.
