This is a current position calculation device that calculates the current position by sending the information to the entire image processing device 6 and also calculates the movement position from the initial setting point based on information from the direction sensor 1 and distance sensor 2. , the t-fc gap processing device 6 generates a map image of the area based on the map data and current position information of the area corresponding to the area selection key 3, and displays the current position on the image display monitor 7. It is something.

With the in-vehicle navigator device configured in this way, it is necessary to set the current position of the own vehicle before departure, and to do so, the area selection key 3 must be manually operated to display the required map on the full image display monitor 7. I was going there.

[Problem that the invention seeks to solve]

Conventional navigator devices, as described above, first need to display the map necessary to set the current position of the wheel, and for this purpose, a transparent map is displayed on the display in order to use the map sound. The operation involves installing all the film-like objects, manually inputting the code number of the necessary map, etc., and outputting the necessary map.90 However, these manual operations are extremely troublesome when operating an in-vehicle navigator. It was something.

The present invention has been developed to solve all of the above-mentioned problems, and its entire purpose is to provide a practical navigator device that does not require troublesome manual operations and is easy to operate.

[The tth method to solve all problems]

The in-vehicle navigator device according to the present invention includes a satellite 111-
The own vehicle position detection device receives and detects the own vehicle position, and from this detected round-eye vehicle position data, map data is recorded corresponding to each area and the map data of the area including the own vehicle position is stored in the friend storage device. A calculation processing device that performs all calculations and extraction, an image processing device that displays a map image including the own vehicle position and the own vehicle position on an image display monitor based on the extracted map data; It is.

[For production]

In the in-vehicle navigator device of the present invention, the calculation processing device automatically calculates the storage address of the map data including the own vehicle position in the storage device based on the data of the own military position detected by the own military position detection device. The map data is extracted and the vehicle position is determined based on this map data. A map image including the map image and an image of the vehicle's position are displayed on the image display monitor.

〔Example〕

FIG. 1 is a block diagram showing the configuration of an on-vehicle navigator device according to one embodiment of the present invention. In the figure.

Reference numeral 8 denotes a satellite receiving antenna section, and reference numeral 9 denotes an m-star radio wave 1r such as GPS (global positioning system), which receives the radio wave and outputs the detection data of the absolute position of the vehicle to the calculation processing device 110 by making full use of this radio wave. It is a position detection device.

Recently, various systems for detecting the position of one's own vehicle using satellites have been announced, and this own military position detecting device 9 is a unique vehicle position detecting device that uses satellites.

In addition, 4 is a storage device for recording map data corresponding to each region.
It is assumed that the district is made up of district A, district B, district C, D, etc.). In FIG. 4, A.

B, C, and D are water supplies in each area, Xn-1, Xn #
n+x is meridian W h Yn-1* Yn w Yn+t
*Yn+s indicates latitude (Xn-t < X
n<Xn+t・”, Yn-z<Yn<
Yn+t < Y (assumed to be 4). Furthermore, an example of address allocation in the storage device 4 is shown in FIG. 3. In FIG.
~3FFF address, C area is 4000~4FFF address, D
The districts are stored as district data at addresses 5000 to 5FFF. At the beginning of each district data, information on the district area shown in Figure 4 is provided, for example, in district A, address 2000 is Xn-1, address 2001 is Xn, and address 2002 is Yn-1.

yn at address 2003, A at addresses 2004-2FFF
District map data is stored. Figure 5 shows this in detail, and other districts are memorized in a similar manner as shown in Figure 5.

10 is a calculation processing device, which is detected by the own army position detection device 9 and outputs the position data of the round army (longitude xo I latitude y).

) exists in the first address part of all district data (for example, 2000 to 2 for district A).
003Ti) data and automatically check the calculations sequentially. For example, whether the own vehicle position (Xo, Yo) is in district A is determined by the district area starting from address 2000.

- Check the calculation, and if it is not satisfied, next is 2000″ from 4th place to 4th area data of area B at address 3000 of the part-time job, -i < Xo ≦ Xne Yn < Yo
The calculation is checked to see if ≦Yn+z k is satisfied, and if it is satisfied, it is determined that the area is in that area. If you are still not satisfied, check the C area area data of address 4000 at the part-time job in the same manner as above, and check the own vehicle position (
Eri decides which district Xo *Yo) is.

Determine the storage address of the map data of the area including the own vehicle position. For example, if it is determined that the vehicle's location is in Area A, 20
Does the calculation processing device 1011 know that district data including the own vehicle position exists at addresses 00 to 2FFF and that map data exists at addresses 2004 to 2FFF? : Determined by construction.

Computation processing device 10KJ: When the memory address of the map data of the district including the vehicle position (for example, addresses 2004 to 2FFF when the vehicle position is in district A) is determined, the map data and current position data (Xo , Yo) are sent to the image processing device WL6. The image processing device 6 is a device that displays this map data and current position data (Xo + Yo) on a k-image display monitor as a map image and an image of the vehicle's position, and the single-image display monitor 7 displays a map image including the vehicle's position. and the location of your vehicle is automatically displayed.

〔Effect of the invention〕

If the above-mentioned method is implemented in the in-vehicle navigator device of the present invention, the vehicle position detection device will be modified to detect the absolute position of the steering wheel.
From this own army position data, the calculation processing device automatically extracts all the map data containing the own army position in the storage device, and displays the map image including the own army position and the own army position. This eliminates the need for cumbersome operations such as manually adjusting the location of the bus before departure to display the necessary map, and has the effect of making operations easier.
