(2) Remote Controller 50 FIG. 2 shows the remote controller 50. The remote controller 50 executes various settings for the navigation device shown in FIG. A rectangular recess 51 is formed at the center of the surface of the remote controller 50, and three rows ×
Four stages = 12 key switches (input means, switching means) 52 are provided. By depressing the key switch 52, the display symbol 60 is activated to input information, and the various processes are executed.

On the surface of the key switch 52, an identification portion 56 of an elliptical projection is provided. The key switch 52 selected by touching the identification unit 56 with the tip of a finger or the selected position of the key switch 52 is tactilely identified without visual recognition. The key switch 52 and the identification section 56 indicate the position or area of the means for inputting information.

An infrared coupler 53 is provided on the inner side surface of the concave portion 51.
It is detected whether a finger, a pen or other input medium has been placed thereon. Three infrared couplers 53 are provided on the upper side and the lower side of the recess 51, and four on each of the right side and the left side of the recess 51. Each of the infrared couplers 53 is a pair. Is a light emitting type and the other is a light receiving type.

The light emission of each of these infrared couplers 53 is sequentially switched by matrix control, and based on the non-light reception of the emitted infrared coupler 53 and the infrared coupler 53 to be received, the position where the finger or the like is put is determined and Is detected. The key switch 52 corresponding to the place where the finger is put has not reached the input operation (operation, operation, switching operation, switching operation), but the key switch 52 is in a selected state.

Thus, it is detected that at least one of the plurality of key switches 52 is selected in a state where the key switches 52 do not reach the input operation. Based on the detection result, the selected key switch 52
The display state of the display symbol 60 on the display 33 corresponding to is changed as described later.

An infrared light emitting section 54 is provided on the upper end face of the remote controller 50. The selected content of the infrared coupler 53, that is, whether or not any one has been selected, which has been selected, and the input content of the key switch 52, that is, Information as to whether any has been entered and which has been entered is transmitted using infrared. The transmitted information is sent to the remote control interface 15 of the navigation device, where the information is input and various processes are executed.

Another switch 55 is provided on the remote controller 50. The power of the navigation device is turned on by operating the power switch among the other switches 55, and the scale of the display map on the display 33 is switched by the detail switch / enlargement switch of the other switches 55. Each of these key switches 5
2, switch 55, infrared coupler 53, infrared light emitting section 5
The drive, detection, and control of 4 are executed by a CPU (not shown) in remote controller 50 and other control circuits (not shown).

The remote controller 50 is separated from the display 33, and information / data is transmitted to and received from the display 33 by infrared rays. However, in some cases, the remote controller 50 and the display 33 are connected to each other by wireless or wired transmission and reception of information / data.

Since the infrared coupler 53 is always activated before the operation of the key switch 52, the selected key switch 52 can enter the input operation in the selected state. The input operation of the key switch 52 is possible after the key switch 52 is selected. That is, unless the key switch 52 is selected, the input operation of the key switch 52 is impossible.

Since the interval or width between the infrared couplers 53 is larger than the thickness of an adult finger or the thickness of an input medium, one key switch 52 is always selected by one selection. However, the interval or width between the infrared couplers 53 is reduced, and in some cases, a plurality of key switches 52 are simultaneously selected by one selection.

The number of key switches 52 may be less than 12, for example, one, depending on the case. Even with one key switch 52, the display symbol 60 is selected and information is input as in the case of the twelve key switches. This one key switch 52 is provided at the center below the bottom surface in the concave portion 51,
This one key switch is depressed no matter where on the bottom surface of the one.

In this case, the selection of the display symbol 60 is detected by the fourteen infrared couplers 53. In other words, in the state where the input operation is not reached, which position (which identification unit 56) of the one key switch 52 is selected is detected by the fourteen infrared couplers 53, and is selected based on the detection result. The display state of the display symbol 60 corresponding to the position of the key switch 52 (identification unit 56) is changed. In the following description, a plurality of key switches 52 will be described, but there is actually one key switch.

(3) Group of Key Switches 52 FIG. 3 shows each group of the key switches 52. The number of the key switches 52 is 3 rows × 4 steps = 12. Of these, the upper 3 steps = 9 key switches 52 belong to the first group, and the lower 1 step = 3 key switches 52 belong to the second group. is there. Also, the upper two = 6 key switches 52 belong to a third group, and the lower = 6 key switches 52 belong to a fourth group. Therefore, the third group is included in the first group, and the second group is included in the fourth group.

When the key switch 52 selected is the fourth key switch,
When the group is switched to the third group, the display symbols 60 of FIGS. 6, 8, 10 and 12 are displayed, and when the group is switched from the first group to the second group, FIGS. 7, 9, 11, and 13 are displayed. , FIG. 14 or FIG. 15 is displayed.

The switching of the display symbols 60 is executed only when the selection of the key switch 52 is switched between the first and second groups and between the third and fourth groups. . Even if the selection is switched among the first group, the second group, the third group, and the fourth group, the display symbol 60 is displayed.
Is not switched.

The display symbol 60 at the third level from the above
Appears in the first group when the selection of the key switch 52 moves from the first group to the second group. If the switching of the display symbol is performed only by switching the selection between the first group and the second group,
In order to select the key switch 52 of the switched display symbol 60 in the third row, if the finger is moved to the third row, this display symbol 60 returns to the original state. This is because the third stage belongs to the first group.

To eliminate this inconvenience, the third and fourth groups are provided as described above. This allows
If the switched display symbol 60 does not match the key switch 52 to which the selection has been switched at this time, even if the selection is switched from the key switch 52, the selected display symbol 60 corresponds to the switched display symbol 60. Until the selection is switched from the selected key switch 52, the display of the switched display symbol 60 is maintained. Thus, the input corresponding to the display symbol 60 can be performed without erasing the switched display symbol 60.

(4) Display Processing FIG. 4 shows a flowchart of the display processing. This display process is executed by the CPU 2 in the navigation device based on the operation of the remote controller 50. This display process is started when the display 33 of the navigation device is pulled out, set up, when the ignition key of the vehicle is turned on / off, when the power is turned on or a predetermined switch operation is performed. This power-on is also performed by operating the power switch 55 of the remote controller 50.

First, an initialization process is executed (step SB1). In this process, the navigation program is read from the information storage unit 37. The read navigation program is copied (installed) in the flash memory 3. Thereafter, the program of the flash memory 3 is executed. Furthermore, CPU
2, the work memory of the RAM 5, the image memory 10
Etc., the general-purpose data storage area in each RAM is cleared (step SB1).

Further, the screen of the display 33 is turned on, and some display data is displayed (step SB).
2). This display data is, for example, a map near the current position. This map is a house map, a wide area map, a road map, or the like. In the display examples of FIGS. 6 to 15, a house map is displayed.

The image data of such a map is created by the CPU 2 based on the data 38c, the program 38b, and the data from the current position detecting device 20 or the clock 14, written into the image processor 9 and displayed on the display 33. You.

A finger is put in the concave portion 51 of the remote controller 50 and the key switch 52 is selected (step SB).
3) If the selected key switch 52 is the third group (step SB4) and if the previously selected key switch 52 stored in the RAM 5 is the fourth group (step SB6), the third group is selected. Data indicating the three groups is stored in the RAM 5 (step SB8), and the display symbols 60 (icons) and / or the discriminating frames 61 of FIGS. 6, 8, 10, and 12 are displayed on the display 33 (step SB10). .

The selected key switch 5
2 is a second group (step SB5);
Key switch 52 previously selected and stored in
Is the first group (step SB7), this third group
Data indicating the group is stored in the RAM 5 (step SB9), and FIG. 7, FIG. 9, FIG. 11, and FIG.
5) Display symbol (icon) 60 and / or discriminating frame 61 are displayed on display 33 (step SB).
11). The display frame 60 corresponding to the key switch 52 of the remote controller 50 is replaced with another display symbol 6.
It is distinguished from 0.

The display symbols 60 to be displayed are 3 columns ×
4 rows = 12 pieces or 3 rows x 3 rows = 9 pieces are displayed.
It corresponds to 12 rows × 4 rows = 12 or upper 3 rows × 3 rows = 9 key switches 52. Further, the color of the display symbol 60 corresponding to the selected key switch 52 is outlined and the display state is changed (step SB12,
SB13). In FIGS. 10 to 14, the display symbols 60 corresponding to the upper right, lower right, upper left, lower left, or right and left four key switches 52 among the nine key switches 52 are omitted.

The change in the display state is such that the display color of only the corresponding display symbol 60 is inverted to a complementary color, a frame is added around the display symbol 60, or the brightness or luminance is increased. In this case, on the contrary, the display state of all the display symbols 60 corresponding to all the key switches 52 other than the selected key switch 52 is changed in some cases.

Thus, the selected key switch 52
Of the key switch 52, the currently selected key switch 52 can be easily viewed by just looking at the change in the display state of the display symbol 60 on the display screen of the display 33 without having to look at the key switch 52 one by one. The key switch 52 to be operated can be easily identified. The selection of the key switch 52 is detected by the infrared coupler 53, and the detection data is sent from the infrared light emitting section 54 to the CPU 2 via the remote control interface 15, and the display processing is executed.

Further, a large number of display symbols 60 can be switched only by switching the selection of the key switch 52 without providing a means for switching the display symbols 60. 6 and 7, only the first three symbols in the third row from the top are switched, and the display symbols 60 in FIGS. 8 to 11 are only the second two rows in the third and fourth rows from the top. 12 to 14, only the lowermost three are switched.

Of course, depending on the case, one stage, three stages, two stages, six stages
, Three rows, nine, and all display symbols 60 are switched.
Switching of the display state of the display symbol 60 is performed as follows.
In some cases, the display symbol 60 is newly displayed from a state where it is not displayed, or the displayed display symbol 60 is deleted.

FIGS. 6 and 7, FIGS. 8 and 9, FIG.
0 to FIG. 11, FIG. 12 to FIG. 13, FIG. 14 or FIG.
7 is when the selection is switched from the first group to the second group, and FIG.
6 to FIG. 9, FIG. 9 to FIG. 8, FIG. 11 to FIG.
When switching from FIG. 14 or FIG. 15 to FIG. 12, the selection is switched when the fourth group is switched to the third group. The switching from FIG. 15 to FIG. 12 may be executed by another switch operation. When the key switch 52 corresponding to the input of each initial is sequentially pressed from the state of FIG. Are sequentially selected and displayed.

Thus, the key switch 52 to be selected differs depending on the switching direction of the display symbol 60,
Switching in accordance with the display condition, which matches the relationship between the selection key switch 52 and the display symbol 60, is realized. Of course, depending on the case, the first group and the third group of the key switch 52 may completely match,
For example, the second group of No. 2 and the fourth group completely match.

The switching of the display symbols 60 is performed when the boundary between the first group and the second group of the key switch 52 is exceeded or when the boundary between the fourth group and the third group of the keys 52 is changed. Is executed only when Even if the selection is switched by another key switch 52, the display symbol 60 is not switched.

Further, the switching from FIG. 12, FIG. 13 or FIG. 14 to FIG.
This is when the “initial jump” at the lower right of the two is selected. The switching from FIG. 15 to FIG. 12, FIG. 13 or FIG. 14 is made when a key switch 52 other than the lower right “initial jump” is selected. Also in this case, the processing of steps SB3 to SB13 is performed in the same manner, and the display symbol 60 is switched in response to the selection of the key switch 52.

In this case, the selected key switch 5
2 is the “initial jump” at the lower right (step SB
4) If the previously selected key switch 52 stored in the RAM 5 is other than the "initial jump" (step SB6), data indicating the "initial jump" is stored in the RAM 5 (step SB8). ), FIG.
Is displayed on the display 33 (step SB10).

The selected key switch 52 is other than the lower right "initial jump" (step SB).

(5) Various Processes FIG. 5 shows a flowchart of various processes for navigation in step SB18. In this process, a current position process (step SA1), a destination setting process (step SA2), a route search process (step SA3), a route selection process (step SA4), a guidance / display process (step SA5), and other processes (Step SA6) is executed. Note that the destination setting process (step SA2),
The route search process (step SA3) and the route selection process (step SA4) are not executed repeatedly when the destination is not changed or the moving object is not departed from the route.

In the current position processing (step SA1), the geographical coordinates (latitude, longitude, and altitude) of the moving object on which the navigation device is loaded are detected. In this detection, the GPS receiver 25 obtains the coordinate position of the moving object on the earth surface. The obtained coordinate position of the moving body is stored in the RAM 5 as the current position data MP. The current position data MP is corrected by information input from the beacon receiving device 26 or the data receiving device 27.

In the current position processing (step SA1), the absolute azimuth data ZD, the relative azimuth data Dθ,
The travel distance data ML is obtained from the absolute azimuth sensor 21, the relative azimuth sensor 22, and the distance sensor 23, and arithmetic processing for specifying the position of the moving body is performed. The position of the moving object obtained by this arithmetic processing is compared with the map data stored in the data 38c of the information storage unit 37, and the current position on the map screen is accurately corrected. By this correction processing, the current position of the moving object can be obtained even when a GPS signal cannot be received in a tunnel or the like.

In the destination setting process (step SA2),
The geographical coordinates of the destination desired by the user are set as the registered destination data TP. For example, the coordinates of the destination are specified by the user using a road map or a house map displayed on the display 33. Or, from the itemized list of destinations displayed on the display 33,
The destination is specified by the user. When the user performs a destination designation operation, information data such as geographic coordinates of the destination is stored in the RAM 5 as registered destination data TP.

In this destination setting process, the display of the “individual name”, “TEL”, “50 sounds”, “route”, “switch”, “nearest”, and the characters (hiragana) in FIGS. The operation of the key switch 52 corresponding to the symbol 60 is determined, and the destination is searched from the content corresponding to the operated display symbol 60.

In the route search process (step SA3), a plurality of routes are searched from the guidance start point data SP (including the departure place, the same applies hereinafter) to the final guide point data ED (including the stopover point, the same applies hereinafter). You. The route search is performed in the order of the values of the priority tables PTD1, PTD2, and PTD3. That is, if the magnitude of the value is priority table PTD2> priority table PTD1> priority table PTD3, the second search condition, the first search condition
The path is searched in the order of the search condition and the third search condition.
The guidance start point data SP includes the current position data MP
Is set, or node data on the guidance target road close to the current position data MP is set.

In this route search process, the operation of the key switch 52 corresponding to the nine arrow display symbols 60 among the display symbols 60 is determined, and the display map is scrolled in the direction corresponding to the operated display symbol 60. Is done.

In the route selection process (step SA4), a process of selecting one route from the plurality of routes searched in the route search process of step SA3 is performed according to a change in the position of the moving object. That is, when the moving object starts moving in a state where a plurality of routes have been searched in the route searching process of step SA3, a process of automatically determining which of the plurality of routes the moving object is moving is performed. Done. Then, when it is determined that the moving object is traveling on only one search route, the route selection processing (step SA4) ends.

In the guidance / display processing (step SA5),
The guidance route obtained by the route selection process (step SA4) or the route re-search process is displayed on the display 33 with the current position of the moving object as the center. The guidance route displayed on the display 33 is displayed on the display map so as to be identifiable. For example, on the map displayed on the display 33, the guide route is displayed in a different color, for example. Further, according to this guidance route, road guidance information is output from the speaker 13 so that the mobile body can travel favorably. Accordingly, various types of guidance information are displayed on the display 33 as needed. The image data for displaying the guidance route is
The road map data around the current position of the data 38c in the information storage unit 37 or the house map data around the current position is used.

The switching between the road map data and the house map data is performed under the following conditions. For example, a guide point (destination, drop-in place, intersection, etc.) from the current position
Distance, the speed of the moving object, the size of the displayable area, the user's switch operation, or the like. In addition, guidance points (destinations, stopovers, intersections, etc.)
In the vicinity, an enlarged map near the guide point is displayed on the display 33. Note that a simplified guidance route image is displayed on the display 33 in some cases instead of the road map. In the simplified guide route image, for example, display of geographical information is omitted, and only necessary minimum information such as a guide route, a direction of a destination or a stopover place, and a current position is displayed.

In other processing (step SA6), the nearest facility processing may be executed. The nearest facility process is a process of searching for and specifying a stopover place (facility, etc.) other than the registered destination data TP. The data relating to the drop-in place is determined using a map displayed on the display 33 or item information. The nearest facility processing is performed in the same manner as the destination setting processing in step SA3.

In the other processing (step SA6), for example, it is determined whether or not the traveling position of the moving object is along the calculated guide route. That is, when it is detected that the moving object has deviated from the guide route, the state flag for starting each process is set so that the route is searched again. Also, it is determined whether or not a destination change command has been input by a user's switch operation.

In this other processing (step SA6), four or eight of the display symbols 60 shown in FIG.
The operation of the key switch 52 according to the display symbol 60 of one arrow or three or five arrows in FIG. 7 is determined,
