Now, in a vehicle equipped with components 1 to 8 shown in section 1v4, when the key switch is turned on at the start of driving, each electric system is activated by receiving the entire power supply from the onboard battery. Then, the microcomputer 4 receives the stabilized voltage from the stabilized power supply circuit and enters the operating state, starting step 100 in FIG.
Then, the arithmetic processing station is started, and the process proceeds to an initial setting routine 200, where the registers, counters, latches, etc. in the personal computer 1 are set to the initial state necessary for starting the arithmetic processing. After this initial setting, the calculation processes from the mode calculation routine aOO to the trajectory deletion calculation routine 600 are repeatedly executed at a cycle of about several tens of meters866.

That is, in this mode calculation routine 800, the map mode and the character 1000 characters are selected, and the content corresponding to that mode is displayed on the ORT, and when in the map mode, the cursor indicating the current position of K11-1 is displayed. When in the character mode, arithmetic processing is executed to enable movement and designation of a specific area on the map, and the current position calculation routine 400TIC is executed.

In this current position calculation routine 400, the current position data and traveling trajectory data to be stored in the eighth graphic memory 21 in the FiORT controller 5 are

On the other hand, when the touch data is not data indicating a mode change, that is, data when a touch area other than 84 in FIG. When the mode change determination step 304 becomes No, the process proceeds to the cursor movement determination step 807. If this cursor movement foot step is 80 meters, is the touch data the data when any of the touch areas 81.88.85.8g and 40.41 is pressed (cursor movement data)? If 1 touch day # is not data for cursor movement, the judgment becomes NOi and this mode operation routine 8o is executed.

However, if the touch data is cursor movement data, the determination becomes YB2 and the process proceeds to cursor movement calculation step 808. In this cursor movement calculation step 808, in accordance with the touch data, the cursor at the current position displayed on the ORT display device 6 is moved northward, indicating that this touch data is data for pressing the 88 touch areas of s#iss. Change the storage contents of the current position data in the second graphic memory 8 in the KORT controller JlIK so that the current position is moved by a predetermined distance (the current position on the display screen is stored in the ordinary person M4C as the X, Y coordinates relative to the display surface) , change the values of the
``If the data corresponds to the press of the touch area of ``141'', the cursor is moved southward, and if the data corresponds to the press of the touch area of flk88, the cursor is moved by a predetermined distance to the east. The operation IJI!11111It- to change and destroy the stored contents of the current position data is executed, and one operation process of this mode operation routine 300 is completed.

On the other hand, if the determination in the map mode determination step 308 is No.
If so, the process advances to mode change determination step 809, and the mode change j! is performed by the same calculation process as in mode change determination step 804. Whether or not fPh is determined. At this time, when the mode is changed and the determination becomes fYE8, proceed to the map mode setting step BIOK and set the contents of the mode area in M4C to the map mode L1 travel route data conversion step 811
Proceed to (31L?) to convert the driving route data of the first graph in the controller S. Calculate the coordinate transformation value between the absolute coordinate data (recorded in the header shown in Figure 4) and the absolute coordinate data on the previous map of the district, and then calculate the coordinate transformation value based on this calculated value. The data of the traveling side part in the graphic memory 22 of Tomi is converted in a sliding manner, and the X and Y coordinate data in the M4C is similarly converted by K.Then, the process proceeds to map data reading step 811. When the map data VrI! of the sumo wrestler tape 8a is inputted via the collecting device 8, the map data of the sumo wrestler tape 8a is inputted to the first graphic memory BI.
If K is output, proceed to map switching signal output step 81B and press C.

This occurs, and one operation m'mt of this mode operation routine 800 is completed. That is, when switching from the character screen to the graphic 111rIIJ of the map that is separated from the previous one, the above calculation process is executed, 1) the current map data is stored in the first graphic memory 21, and 1) the current location corresponding to this map is displayed with the travel trajectory and The contents stored in the eighth graphic memory 2B are converted so as to modify the cursor indicating the current location. This allows the location v! to be displayed on the CRT display device 6! Even if J-bh is switched, the travel trajectory and current position t can be displayed in the area corresponding to the map.

On the other hand, the determination tIh in the mode change determination step 80G
If NO, character calculation step 81441j is also executed.

In the case where the Yaratata calculation step 814 is reached,
Since the character mode is set and a character switching signal is being issued to the video controller 86, the CLLT display device 6#i displays a character mode as shown in FIG. The numbers 011-4-68 shown in the center of this character screen are numbers that designate regions, regions, and districts, and are updated by adding and decrementing each Wk#i increment switch by l, and decrement) switch 6! is subtracted and updated by l at , set at set switch 68, and reset switch black 4f.

When a registration instruction is generated from the registration switch 8a (in the registration state), the determination is The mode becomes vine 8, and the process proceeds to map mode determination step 816 b0.Here, it is determined whether or not the map mode is selected by the same calculation process as in map mode determination step 308 described above. At this time, if the determination becomes YB2 in the map mode, the process advances to point coordinate registration step 817, and the map number stored in the Omu M40 and the XSY coordinates of the current location (by this time, the cursor is registered and the friend point is (need to be set in advance) is stored in the registration area in the RAM 4C (the registered storage contents up to that point are updated), and one calculation process of this mode calculation routine 800 is completed.

Further, if the determination in the map mode determination step 816 is NO, the process does not proceed to the point coordinate registration step 81'F, and the calculation process in step 1- of the mode calculation routine 800 is completed.

Next, the registration determination step 315 &! :If the determination is NO, that is, if no registration instruction has been issued from the registration switch 8 (in the M output state), the process advances to map mode setting step 818 and the contents of the mode area in RAM 4C are set. (In some cases, you may forget to set it to map mode and it is set to horse map mode), Travel meridian data conversion step 8

In the case of Jin, the reading device 11tfliJll is used to search for the corresponding land using the map number stored in the registered area in the above-mentioned M4C, and the traveling meridian data replacement step 81
The eighth graphic memo 933 is created using the same calculation process as in 1.
Convert the travel trajectory data in a sliding manner,
Furthermore, the data representing the current position is changed to the x11 coordinate value recorded in the registered area in ILAM6C, and the process proceeds to map data reading and outputting step 811. In other words, you can move your entire current position to a specific point on the map that has already been registered.

Therefore, the mode calculation routine sOO'' shown in FIG.

Further, the determination in the first X distance determination step 404 is N
If O, the eighth X distance determination step advances by 4 degrees, and it is determined whether the X distance data DX has become a value of 1601n or less. At this time, if the value of the X distance data DXflh is less than 59 m, the judgment power becomes Y18, and the process proceeds to the X distance addition step 408, where the value of 60 m is added to the X distance data DI, and the process proceeds to the display movement step 09. te 8 mouths 14 (
The X, Y coordinate data trs om stored in 3 is converted in the negative direction (west direction), and the traveling locus data in the 8th graph ink meter 7 ml is also moved accordingly.

Then, when the judgment in the second X distance judgment step 407 is NO, after a certain display movement step number 06.409, the process proceeds to the Y component display movement processing routine 410, and the Y component display movement processing routine 410 is calculated. The same determination and arithmetic processing as in steps -O- to 109 above are performed on the I-distance data DYK. (If the Ye1m data DY is a value K”lk that is greater than or equal to the positive or negative direction, then the value K”lk is
The X%Y coordinate data within and the traveling locus data within the third graphic memory zz are moved by I+O1n in the corresponding direction. ) Then, the process proceeds to the next distance flag reset step 111 and the distance lIl! 7 lags and 7 F's.

That is, the current position calculation routine 40 shown in FIG.
At 0, q, the X and Y coordinate data in the 8mm M40 and the travel locus data in the graphic memory gB of the IIB are converted regardless of the stroke displayed on the CRT display device 6.

The graphics memory mBK is stored in the graphics memory mBK, and when the display flag is reset, the display data read from ll1RmM40Th is used to display the one cursor part that does not include the paper travel trajectory, and the data is cleared from the eighth graphic memory 13. . Therefore, on the CRT display device 6, a cursor (consisting of nine pixels) indicating the current position blinks at a cycle of 0.6 seconds.

Next, the detailed calculation processing 11 of the trajectory deletion calculation routine 600 will be explained. This trajectory erasure calculation routine 600'', company c, starts its calculation processing from the switch input determination step 601 in FIG. The determination is N0IIC and this trajectory deletion calculation routine 60

Change the current position data and travel trajectory data sequentially, and select the screen of the CRT display device 6 according to the specified mode. (including)
If the character mode is selected, a character screen '& scissors image for map designation shown in FIG. 6 is displayed. Also,
Registration switch 881 Set switch 8b operation state 1II
From c, when registering, the coordinates and map number of a specific point (set from the cursor) are stored, and when the cursor 1 is registered, the cursor 1 is moved to the registered specific point.

Next, a second embodiment in which a part of the mode calculation routine 300 shown in FIG. 8, which corresponds to the above embodiment is modified, will be described with reference to the calculation flowchart shown in No. 11@l.

1st! The figure shows map mode setting step 81 in FIG.
This is a modification of the arithmetic processing up to the map switching signal output step 818 such as STh, and the map mode setting step +1
After 118, the map number determination step 31O is proceeded to, and the map number stored in the memory area M4 ('4 in 3) corresponds to the map number stored in the first graphic method 4911r. It is determined whether the map number is the same as the map number stored in M60, and if it is the same, the determination becomes YB2, the process proceeds to the current position movement step 881, and the map number is stored as is in M40. X representing current position
, (2) The coordinate values are changed to the X5yll target value stored in the 51 record area in the RAM 1C, and the process proceeds to map switching signal output step 818.

Further, when the determination in the map number determination step ago is NO, the driving route data conversion step 819 and the map data reading output step 81! are carried out similarly to the calculation processing in the first embodiment. After t-, the process proceeds to map switching signal output step 818.

That is, when the registration switch 8a is released from the on state and the set switch 8b is turned on, a friend map corresponding to the map number stored in the registration area 11M40 is stored in the first graphic memory 11. In case,
There is a person who controls the reading device 8 and warns the new friend not to read the map data.

In the above embodiment, one switch abt is used, but it is also possible to use a plurality of switches so that multiple locations can be registered and added one after another.

Further, in the above embodiment, the point coordinates to be registered are determined based on the position of the cursor representing the current position, but a numeric keypad may be provided and the point coordinates may be entered manually using numbers.

In addition, although the direction detection is performed using geomagnetic detection, it is also possible to use a method that determines the relative direction of the vehicle with respect to a reference direction.

Another touch panel part? and set switch 8bK
In order to prevent movement of the cursor due to erroneous operation, a prohibition switch may be provided to prohibit movement of the cursor when the switch is turned on.Furthermore, the touch panel section? Although a method for moving the cursor vertically and horizontally has been shown, means for moving the cursor not only vertically and horizontally but also in any angular direction #IC may be used. Further, instead of the instruction to move the cursor by the touch panel unit 7, the cursor may be moved by detecting an instruction to move the cursor by the driver's voice.

As described above, in the present invention, a specific point on the map is memorized in advance by foreign bank operation, and when a movement instruction is issued, the routine position of the vehicle is moved to the memorized specific point. yo(doing so, example F!, '1lF
- Register the location of your home as a specific point as the starting point to use, and when the operation starts in d11 (you can move your current location to a specific point such as your home with a simple operation without having to go through the trouble of managing one operation). It has excellent effects on its own.
