Stores scale data, tilt data, etc. In this embodiment, an atlas is prepared that includes a wide-area map with the smallest scale, a normal map with a medium scale, and/or a detailed map with the largest scale (meaning that some locations are represented by multiple types of maps). Using the latitude and longitude of the lower left point of each map and the latitude and longitude of the upper right point as reference position data, and the scale of the map as scale data, calculate the inclination of the meridian and the X line of the map. It is stored as tilt data. Note that these data have a correlation with each other; for example, if the latitude and longitude of the lower left point of each map and the latitude and longitude of the upper right point are given, the scale and meridian of that map can be calculated. You can know the slope with the X line. Therefore, if calculations are performed when necessary, it is possible to reduce the number of stored data.

C1 Control: Next, the control operation of the controller 310 will be explained with reference to the flowchart shown in FIG.

When the controller 310 is started by powering on, in step 1 it executes initialization processing to initialize input/output ports, initialize flags and variables, etc.
After that, steps 2 to 6 are repeatedly executed. Step 2
In step 3, a reading process for reading key operations is executed, and in step 3, a process associated with the operated key switch is selected.

In this case, when the key switch 341 is operated, “
When the key switch 342 is operated, the key switch 34 executes the "destination input process".
When key switch 341 and 344 are operated, ``display switching process'' is executed, when key switch 344 is operated, ``map change process'' is executed, and when key switches 341 and 344 are operated at the same time, ``position correction process'' is executed. Also, when the key switch 352 is operated, the route 1-1 is selected from among the multiple routes registered in the ``destination input process''.
A process is performed to select A and set it in a usable state. In exactly the same way, when the key switch 353 is operated, route B is selected, when the key switch 354 is operated, route C is selected, and when the key switch 355 is operated, route D is selected. served,
Each is set to a usable state. It is assumed that no processing is selected for any other operation (other).

In step 4, the selected process is executed, in step 5, a calculation process for calculating various data is executed, and in step 6, a display/alarm process for performing various displays and alarms is executed.

(A) Arithmetic processing: The arithmetic processing will be explained with reference to FIGS. 5a and 5b. Note that the atlas 4 is currently stored in the atlas storage room 30-4, and an atlas number PM that specifies the atlas and a page number PP that specifies the opened page are set. shall be.

Here, first, the latitude data and latitude data of the current position of the car given by the GPS integrated controller 2 are read, variables LA (Latitude) and LO (Longitude) are set respectively, and each variable is set to the latitude correction value L. A o or latitude correction value LA
, (step 5-1.5-2).

These latitude correction values LA are values set by position correction processing to be described later, and are each initialized to O before the processing is performed.

Next, from the ROM 314, the standard position data associated with the map specified by the current atlas number PM and page number PP, that is, the latitude LA of the lower left point of the map, and the map's Latitude of the upper right point LA2
．． The latitude LO2 is read and it is checked whether the current position of the car indicated by the corrected variables LA and LO exists in a rectangular area specified diagonally by these points (step 5-
3). If it exists, its current position is converted into the xy coordinate system on the display board 38, and the optimal X line and X line for displaying it are selected (step 5-5). More specifically,
... (1) And, Y= (LA-LAI)・(J+1)/(LA4-LA
, )... (2) Calculate the X coordinate X and y coordinate Y of the current position by performing the calculations shown in , and then round off the coordinate X to find the LED pair at both ends of the X line that is optimal for display. Number XC
By rounding off the coordinate Y, the numbers YC of the LED pairs at both ends of the X line optimal for display are obtained.

After that, in step 5-6, the distance between the current position and the destination, that is, the remaining distance RD is determined, and in step 5-7
In step 5-8, the direction of travel of the vehicle (azimuth with north as reference) is determined from the change in the current position, and in step 5-8, the direction of the destination (azimuth with north as reference) is determined. Note that if a GPS-integrated controller is used that calculates the current position of the vehicle as well as its traveling direction, the calculation in step 5-7 becomes unnecessary.

On the other hand, if the current position of the vehicle indicated by the variables LA and LO is not on the map specified by the map book number PM and page number PP at that time, the process proceeds to step 5-4 and a search process is performed.

In this process, first, the total number of pages PNM of the atlas specified by the atlas number PM is read out from the ROM 314 (Step 5-4-1), page counter PC, page number PP, wide area map page number WP5 normal map Clear page number MP and detailed map page number DP, and set variable DS11$.

O is substituted into DS12$ and DS11$ (step 5-4-2).

After that, while updating the page number PP sequentially, check whether the current position is present on the map specified by the page number PP in the same way as above (Step 5-4.5-4-4
). At this time, if the current position exists in the map under consideration, the page counter PC is incremented by 1 (step 5-4-5), and if it is a wide area map, the variable DS11
Substitute "W I+" for $ and set the wide area map page number WP to the page number PP at that time, and if it is a normal map, page DS 12 Substitute "M"°° for $ If it is a detailed map, set "D'" to the variable DS 13 $, and if it is a detailed map page, set DP to the current page number PP (Step 5-4-6.5-4- 7).

When the above study is performed on the maps of all pages of the atlas specified by the atlas number PM, the page counter PC becomes 1 or more when there is a map including the current location in the atlas, and becomes O when there is no map. Therefore, when the page counter PC is O, the map book number PM is incremented by 1, and the above search process is repeated from the beginning (steps 5-4-9 and 5-4-10). However, the atlas number PM
When the value exceeds the total number of atlases MM by one increment, the value is set to 1 (step 5-4
-11.5-4-12).

When the page counter PC becomes 1 or more and it is known that there is a map that includes the current location in the atlas being considered, the variable D
The code obtained by combining S11$, DS12$, and DS11$ in this order is assigned to the variable DS1$ (Step 5-4
-13). That is, the variable DS1$ is assigned a code as shown in Table 1 below depending on the number of maps including the current location in the atlas and the type of each map.

Table 1 However, in Table 1 above, "Ot+" indicates that the current position is included, and "×°°" indicates that the current position is not included.

Finally, a page of the map suitable for display is set as the page number PP. In this embodiment, in order to read the position and change the map as the car moves, the priority is set in the order of normal map, wide area map, and detailed map, so if the normal map page number MP is not 0, the value is When the normal map page number MP is 0 and the wide area map page number WP is not 0, use that value, and when the normal map page number MP and wide area map page number WP are O, use the detailed map page number DP. page number P
Set P (step 5-4-14.5-4-15
).

In this way, once the atlas number PM that specifies the atlas that has the map that includes the current location and the page number PP that specifies that map are obtained through the search process, the process proceeds to step 5-5 and subsequent steps, and the same process as described above is performed. conduct.

(B) Display/warning processing: The display/warning process is shown in FIG.

In this process, necessary instructions are sent to the drive circuits 312, 313 and output ink faces 315, 316, and the liquid crystal display 32. It controls the display of the matrix LED 33 and coordinate display LED groups 36 and 37, sends necessary instructions to the drive circuit 317, and controls the sound of the buzzer BZ. Furthermore, when passing through a registered point, a process is performed to update and set the next registered point as a new destination.

In display control of the liquid crystal display 32, the liquid crystal display 32
Above is a number indicating the route the car is currently traveling on and the registered point it is heading towards, an atlas number PM that identifies the atlas that has the map that includes the current location, a page number PP that identifies that map, and a scale of the map. The code “W II
“M” or “D゛°.

Then, when the remaining distance RD and the selection variable DM for selecting the display is O, a "progressing direction" message is displayed, and when it is 1, a "way point direction" ° message is displayed. In other words, for example, if the map book number 5 is The current position exists on the regular map of the page specified by page number 34 of the specified atlas, and the distance from there to the destination is 51.4 km.
If m, a display as shown in FIG. 13a appears on the liquid crystal display 32 on the condition that the selectivity @DM is O,
On condition that the selection variable DM is 1, a display as shown in FIG. 13b appears on the liquid crystal display 32.

Therefore, when the map in the atlas shown in this way is not open, it is removed and reset. After that, the remaining distance RD and a predetermined short distance K are compared,
It is determined whether the vehicle is approaching the registered point or not, and when the vehicle approaches the registered point, a buzzer 34 is sounded for a certain period of time.

In display control of the matrix LED 33, one of the patterns shown in FIGS. 14a to 14i is displayed by turning on/off each LED constituting the matrix LED 33. In this case, if the selection variable DM is O, the top direction of the map of the page specified by the page number PP of the atlas specified by the atlas number PM (some maps do not point north) The direction of travel of the car as a reference is displayed with an arrow, and if the selection variable DM is 1, the direction of the registered point with respect to the direction of travel is displayed with an arrow. That is, for example, when a car is moving to the right on the map of the page specified by the page number PP of the atlas specified by the atlas number PM, the matrix LED 3 is displayed in the direction of travel display.
3, the pattern shown in FIG. 4f is displayed, and when the registered point is on the left hand side in the direction of travel, the pattern shown in FIG. 4d is displayed on the matrix LED 33 in the destination direction display.

In the display control of the coordinate display LED groups 36 and 37,
LE specified by the number XC of the LED stage 36 for displaying the X coordinate
The D pair and the LED pair specified by the number YC of the y-coordinate display LED group 37 are turned on.

(C) Scale change process When the operation of the key switch 341 is read in step 2, a scale change process is executed in step 41. This process will be explained with reference to the flowchart shown in FIG.

Here, each time the key switch 343 is operated, the page number PP and wide area map page number WP are displayed.

Regular map page number MP and detailed map page number DP
The page number PP is updated according to the conditions shown in (steps 41-1 to 4l-4). In other words, key switch 3
When the map selected when the operation in step 43 was performed is a wide area map (PP=WP) and there is a regular map that includes the current location (MP≠O), or the map selected at that time. is a detailed map (PP=DP), there is no wide-area map that includes the current location (WP=O), and there is a regular map that includes the current location (MP-#O), then the page number P
P is the normal map page number MP, variable DS2S is the code "
Step 41-4-1
1.41-4.12), the map selected when the key switch 343 was operated is the normal map (PP=
MP), Ga, when there is a detailed map including the current location (M
P≠o), or the map selected at that time is a wide area map (PP=WP), and there is no regular map that includes the current location (MP=0), but there is a detailed map that includes the current location. For (DP*O), set the detailed map page number DP to the page number PP, and set the code "00D'" to the variable DS2$.Step 41-4-21.4l-4-
22) When the map selected when the key switch 343 is operated is a detailed map (PP=DP), or when there is a wide area map that includes the current location (WP≠0), or The selected map is a normal map (P
P=MP), and there is no detailed map including the current location (
DP=O), when there is a wide area map that includes the current location (WP
≠0), the page number PP should be set to the wide area map page number WP, and the variable DS2$ should be set to the code "woo" at step 41-4-31.4l-4-32). Under conditions other than these, the key switch 343 is set. Nothing is done when the operation is performed.

After this, if the variable N is 0, set it to 1 and set the variable DS$
Set the value of the variable DS1$ to the variable N, and if the variable N is 1, set it to 0 and set the value of the variable DS2$ to the variable DS$.Steps 41-5 to 4l-7-), for the drive circuit 312. to display the contents of the variable DS$ (step 4).
l-8L The above process is repeated until the return key 35 is operated.

As mentioned above, the variable DS1$ is set with a code indicating all maps including the current location, that is, the type of map that can be selected, and the variable DS2$ is set with a code indicating the type of map selected at this time. Since this has been set, while this scale change process is being executed, codes indicating the selectable map type and the selected map type are alternately displayed on the liquid crystal display 32.

(D) Flowchart 1 shown in FIG. 8a in step 42 of reading the operation of the key switch 342 in step 2 of destination input processing
・Purpose indicated by ・Execute force processing. here,
In step 42-1, the drive circuit 312 is instructed to display the destination message, and then in step 4
In 2-2, a position setting subroutine is executed. This position setting subroutine will be explained with reference to the flowchart shown in FIG.

In the position setting subroutine, first, the flag F is reset, and the map book number MN and page number P for position setting are set.
N is set to 0, and numbers XC and YC of each LED pair are set to 1 (step 101).

Next, the key switch operation is read, the map book number MN and page number PN are displayed on the liquid crystal display 32, and each LED pair specified by the numbers XC and YC is lit (step 102). At this time, each time the return key 35 is operated, the flag F is incremented by 1 at step 10.
3, 104), and branches depending on the value of flag F (step 105).

When the flag F is 0, the drive circuit 312 is instructed to display a "map input" message in step 106.

Therefore, the display on the liquid crystal display 32 becomes as shown in FIG. 13c. After this, every time the key switch 343 is input, the map book number MN is incremented by 1 (step 111).
, it is decremented by 1 every time the key switch 344 is input (step 108), but if the map book number MN becomes a value exceeding the total number of map books MM due to this update, it is set to 0 in steps 112 and 113. ), when the value is zero, the entire atlas MN is sequentially displayed on the liquid crystal display 32 in step 102.

When the flag F is 1, the drive circuit 312 is instructed to display a "page input" message in step 114, so that the display on the liquid crystal display 32 becomes as shown in FIG. 13d. After this, each time the key switch 343 is input, the page number PN is incremented by 1 (step 119).
), each time the key switch 3440 is input, it is decremented by 1 (step 116), but when the page number PN becomes a value exceeding the total number of pages PNM due to this update, it is set to 0 (steps 102, 121),
When the value is less than O, it is set as the total number of pages PNM (steps 117 and 118). The page number PN updated here is sequentially displayed on the liquid crystal display 32 in step 102.

When the flag F is 2, the drive circuit 312 is instructed to display the "place setting" message in step 122, so the display on the liquid crystal display 32 becomes as shown in FIG. Each time the key switch 342 is input, the number
), and is decremented by 1 each time there is an input to the key switch 344 (step 131).

However, since the number XC is a number that specifies one of the LED pairs that constitute the X coordinate display LED group 36,
When the value exceeds 1, it is returned to O, and when the value becomes less than O, it is set to 1. Similarly, the number YC is a number that specifies one of the three LED pairs that make up the y-coordinate display LED group 37, so when the value exceeds J, it is returned to 0 and the 0 groove is set. When the value becomes , set J. Each LED pair identified by updated numbers XC and YC is illuminated in step 102.

When the flag F becomes 3, the latitude LAe of the point specified by the coordinates (XC, YC) on the map of the page specified by the page number PN of the atlas specified by the map book number MN.
and the longitude LOe (step 136). Specifically, the reference position data corresponding to the map is stored in the ROM 314, that is, the latitude LA, longitude LO of the lower left point.
1, and the latitude LA of the upper right point! , using longitude LO□, 'LO0=(LO□-Lol)・XC/(I+1)+L0
1... (3) and LA, = (LAz - LAI)・YC/(J+1)
+LAl... (4) Performs the calculation shown by the following formula.

When the above position setting subroutine is completed, the operation of each switch in the input key group 35 is read (step 42-3).
, to route A when switch 352 is operated,
When the switch 353 is operated, the longitude LA is routed to route B, when the switch 354 is operated, the route is route C, and when the switch 355 is operated, the route D is routed to the longitude LA.
The point indicated by e and longitude LOe is registered as a registered point (stages 42-5 to 42-8).

See Figures 8b and 15. Multiple registration points can be registered for each route. The registered points registered for each route are numbered according to the order in which they were registered. Therefore, the number "1" indicates the first stop.

For example, in the case of Lou) A, the latitude is 123. Longitude is 456
The point is the first waypoint AI. Also, the latitude is 123
．． The point whose longitude is 336 is the second waypoint A2, and the latitude is 08.
2. The point with longitude 336 is the third waypoint A3, and the latitude is 0.
82. The point with longitude 216 is the fourth waypoint A4, and the latitude is 080. The point with longitude 216 is the final stop A4 (destination). In the device of this embodiment, the last registered point for a certain route is defined as the destination.

(E) Display switching process 2 When the operation of the key switch 343 is read in step 2, the display switching process shown in the flow chart shown in FIG. 9 is executed in step 43. Here, the key switch operation is read in step 43-1, and if it is the key switch 341 operation, step 4
In step 3-3, the selection variable DM is set to 0, and if the key switch 342 is operated, the selection variable DM is set to 1 in step 43-4, and if the key switch 351 is operated, the process ends. This selection variable DM selects the traveling direction display or the destination direction display in the display process as described above.

(F) Map variable processing When the operation of the key switch 344 is read in step 2, the map change processing shown in the flow chart shown in FIG. 10 is executed in step 44. Here, in step 44-1, the map book number PM is set to 0,
In step 44-2, the drive circuit 312 is instructed to display the ``current location'' message and the ``map input'' message, so that the display on the liquid crystal display key switch 32 becomes as shown in FIG. 13f.

After that, in step 44-3, the key switch operation is read and the map book number PM is displayed, and each time there is an input on the key switch 343, the map book number PM is incremented by 1. In step 44-8), the key switch 344
Each time there is an input, it is decremented by 1 (step 44-5).

However, in this update, if the atlas number PN exceeds the total number of atlases MM, it should be set to 0 in step 44-9.
．． 44-10), if it is less than O, it is the total number of atlases MM
(Steps 44-6 and 44-7). The map book number PM updated here is sequentially -, step 44-3
is displayed on the liquid crystal display 32.

(G) Position correction process 2 In step 2, the simultaneous operation of the key switches 341 and 343 is read.In step 45, the destination input process shown in the flowchart shown in FIG. 11 is executed. Here, in step 45-1, the drive circuit 312
Then, in step 45-2, the position setting subroutine shown in FIG. 12 is executed. This position setting subroutine has been described above, so the explanation will be omitted in step 45.
-2, the drive circuit 312 is instructed to display the PA correction data'° message, so the display shown in FIG. 13g replaces the display shown in FIG. 13c, and the display shown in FIG. The display shown in FIG. 13h is replaced by the display shown in FIG. 13i on the liquid crystal display 32 in place of the display shown in FIG. 13e.

When the position setting subroutine is finished, the input point,
In other words, the car's current position and GP by manual setting
The difference between the current position given by the S-integrated controller 2 and the above-mentioned correction values LA0 and LO are calculated. (Step 45-3).

Specifically, at this time, the latitude LA and longitude LO of the current position of the car, which are set based on the data given by the GPS integrated controller 2, are determined by the previously set correction values LA and LO. Since each has been corrected, subtract them to find the latitude and longitude of the current position before correction, and use that value and the input latitude LAe and longitude L.
Find the difference from Oe. In other words, LA LAo LAe...
・ Perform the calculations expressed by the formulas (5) and LO-LOo-LOe...(6), and use each result as a new correction value L.
A(1, Register as LOe.

(3) Features of the device: - When the power is turned on and the device is activated, the atlas number of the atlas containing the map including the current location of the vehicle and the page number of that map are displayed on the liquid crystal display 32. Therefore, if you prepare the atlas indicated by that atlas number, open the page indicated by that page number, store it in the atlas storage chamber 30-4, and close the display board 38, the current position will be displayed on the LED display. Indicated by lighting. In this case, x-y is displayed on the display board 38.
Since there is a matrix line, it is easy to confirm the current position.

■If there are multiple maps containing the current location at different scales, a normal map with a medium scale will be automatically selected, but it can be changed by operating a key switch. In this case, the page number of the selectable map and the page number of the then selected map are alternately displayed on the liquid crystal display 32.

After the selection is completed, the atlas can be taken out by inserting a finger into the take-out hole 30-3, the map indicated by the displayed page number can be opened, and the map book can be reset.

■Open the map with destinations and waypoints listed, set the atlas, and by operating the key switch, the destination and waypoints will be displayed by the atlas number, map page number, and lighting of the LED pair. Enter. As a result, the destination and transit points are registered and stored as registered points. At this time, the remaining distance to the registration point is sequentially displayed on the liquid crystal display 32.

(2) When the direction of travel is instructed, the direction of travel of the vehicle based on the upper direction of the set map is displayed with an arrow on the matrix LED 33.

Since this arrow corresponds to the direction of travel on the map, the direction of travel of the vehicle can be directly read.

(2) When the destination display is instructed, the direction of the registered point with respect to the direction of travel of the car is displayed with an arrow on the matrix LED 33. This arrow is based on the car, so
You can easily know the direction of the registered point.

Further, as shown in FIGS. 16a to 16b, when the destination display is instructed, the code indicating the route currently being used and the registered point currently heading are displayed as, for example, "A l
", "A2", etc. Also, as the remaining distance, the distance to the registered point you are currently heading to is displayed, for example, "12.0 KM". In this state, , the matrix LED 33 indicates the direction of the registration point.

■If there is a discrepancy between the displayed current position and the current position on the map, set the map on which the current position is shown, and input the correct current position by operating the key switch while looking at it. As a result, the correction value is automatically set, so the current position is displayed correctly from then on.

〔Effect of the invention〕

According to the invention described in claims (1) and (2),
Since information can be input while comparing the position registered by operating the registration switch means with the actual position on the map, inputting information becomes easier and the occurrence of erroneous input is reduced.

Further, according to the invention described in claim (2), since a plurality of routes can be input at once, it is possible to further reduce the occurrence of erroneous inputs.
