On the other hand, the information center B, which is a fixed station, is provided with a data server 11 as a device required for searching for destination location information, an information search terminal 12 for accessing the data server 11, and a large number of vehicles A and others. A telephone terminal 13 for responding to an inquiry from a mobile station is provided.
[0027]
Next, a series of flows from the inquiry of the destination position information to the display of the destination map by the destination guidance system having the above configuration will be described with reference to the flowcharts shown in FIGS. 2 to 5 and the flowchart shown in FIG. .
[0028]
When the service user turns on the ACC of the vehicle, the monitor 2 displays a map display screen (screen A).
[0029]
When the service user presses the menu switch of the navigation operation switch 6, a menu appears on the screen, and when the "destination setting" button is selected from the menu, a pull-down menu appears (screen B).
[0030]
The buttons on the title bar on this screen B are as follows.
[0031]
The “destination setting” button is a button that is touched when setting a destination or a stopover for route guidance.
[0032]
The “confirm route” button is a button that is touched when confirming or modifying the set route.
[0033]
The “register” button is a button that is touched when confirming or correcting a registered point, track, and route.
[0034]
The “view information” button is a button that is touched when viewing various information (guide information, expressway information).
[0035]
The “various settings” button is a button that is touched when various information is displayed or set.
[0036]
The contents of the pull-down menu on screen B are as follows.
[0037]
When the "favorite" item is selected, a screen for selecting from several registered locations is expanded and displayed.
[0038]
When the “from recent destination” item is selected, a screen for selecting from several places set as recent destinations is expanded and displayed.
[0039]
When the item “from position code” is selected, the information center B is called in accordance with the procedure described below to call the position code of the destination (for example, telephone number code, latitude / longitude code, postal code, map area number code, etc.). , What is used in this system), and the destination can be set by inputting the code.
[0040]
When the item "from the Japanese syllabary" is selected, a character screen for inputting the name of the destination by character selection is displayed in an expanded manner.
[0041]
When the "from facility" item is selected, a screen for selecting from destinations by genre such as "station" and "art museum" is expanded and displayed.
[0042]
When the "From telephone number" item is selected, a screen for setting a destination from the telephone number is expanded and displayed.
[0043]
Then, when "From position code" is selected from the pull-down menu of the screen B, the navigation device 1 displays the position code input screen C and executes a pre-installed calculation to execute the position code of the current position and the position of the surrounding area. A code is generated and displayed on the input screen C as a “current position code” and a “peripheral area code”, respectively.
[0044]
The peripheral position code generation logic is shown in the flowchart of FIG. The navigation device 1 detects the current position on the map by a positioning device such as the GPS antenna 4 or a built-in gyro, and reads the position code assigned to the current position or the position code of the narrowest area including the position code ( Step S1) Also reads the position code of the area adjacent thereto, generates position codes of several wider areas including the current position code and the position code of the adjacent area as peripheral area codes (step S2), and inputs the code. It is displayed on the screen C (step S3).
[0045]
For example, as shown in FIG. 7, it is assumed that the position code of the current location or the narrowest surrounding area code including the current location is “236365265” with a 9-digit code number that is a predetermined number of digits. The position code used in the present embodiment includes a large area (area code of “236” from the top three digits) and a middle area (“236365” from the top six digits) for position designation. The area code is set in four stages: a small area (area code of "23636526" from the top eight digits) and a pinpoint (that is, a position code of nine digits "236365265" or the like representing the current position). Shall be.
[0046]
In this case, the area code adjacent to the current position on the map in the up, down, left, right, and diagonally up and down directions is a 9-digit code, only the least significant digit is different, and the eighth digit from the top is a common code number “ 236365261 "," 236365262 "," 236365263 "," 236365264 "," 236365266 "," 236365267 "," 236365268 ", and" 236365269 ".
[0047]
Therefore, the screen C is displayed so that an area code designating an area wider than the position code corresponding to the current position determined by the navigation device 1 can be selected in a stepwise manner. A code that represents three types of areas of different widths: the code “236”, the code “236365” in the middle area up to 6 digits, and the code “23636626” in the small area up to 8 digits. Displayed as code.
[0048]
In this way, the destination input screen C is displayed, the information center B is called by the hands-free telephone 5, and if the operator and the telephone are connected, information necessary for specifying the position code of the destination is obtained. For example, information such as “XXX hospital”, “home center within 5 km radius”, “XX city 市 town △△ address”, etc. is transmitted.
[0049]
The operator of the information center B inputs the information specifying the destination received from the user to the information search terminal 12 to search the data server 11. When the position code of the destination is obtained, the position code is transmitted to the service user by a voice signal. After the search result of the destination position code is obtained, the operator may transmit the destination position code to the service user through a voice synthesizer like telephone number guidance. The service user records the position code number of the destination transmitted from the operator. Then hang up the phone.
[0050]
When the destination position code is obtained in this way, the user inputs the position code on the screen C and sets the destination. For that purpose, the user compares the acquired destination position code with a plurality of peripheral position codes displayed on the input screen C, and selects a peripheral position code having the maximum number of digits that matches from the uppermost position to the lowermost position. For example, assuming that the destination position code obtained from the operator is “236365264”, of the plurality of peripheral area codes displayed on the input screen C, the area code “23636626” from the high-order to the eighth digit which is a small area. Corresponds to this, the surrounding area code "23636626" is selected (screen D). Then, when the decision switch is operated, the surrounding area code “23636526” is displayed in the input window of the destination position code as shown in the screen E.
[0051]
Then, as shown in the screen F, when the remaining lower one digit “4” is touch-input from the numeric keypad and the decision switch is operated, the operator hears the destination position code input window as shown in the screen G as shown in the screen G. All digits “236365264” of the destination position code are displayed.
[0052]
On this screen G, when the user confirms that the destination position code heard from the operator and recorded (or stored) matches the position code displayed in the input window, the user presses the map display button. By touching, a destination is set on the map and a route search process is started.
[0053]
As a result, the navigation device 1 searches the installed map data, and if map data including the corresponding position code is found, a mark indicating the destination is displayed on the monitor 2 together with a map around the destination on the monitor 2. The MK is displayed (screen H). Then, when the service user confirms the position of the destination on the map screen and presses the determination switch of the navigation operation switch 6, the destination is set on the map data of the navigation device 1 (screen I). Then, the navigation device 1 starts a route search (screen J).
[0054]
The route search by the navigation device 1 has the same function as the conventional one. If the determination switch of the navigation operation switch 6 is pressed during the route search, the route search is stopped. If not, the route search from the current position to the destination is reached. (Screen K).
[0055]
When the user presses the determination switch on the route search end screen on the screen K, the guidance route is determined. Then, the navigation device 1 starts route guidance (screen L).
[0056]
Thus, according to the above-described embodiment, in the destination guidance system in which the information center B is inquired of the position code of the destination by an audio signal, the destination is relatively short from the current position. In this case, even when a position code with a large number of digits has to be entered, the number of code digits actually entered by the user can be reduced, and the number of erroneous inputs can be reduced to set the destination. Use can be promoted.
[0057]
In the above embodiment, as the position code, a map number in which a nationwide map is divided into meshes of a predetermined area and a number of predetermined digits is assigned to each mesh is used. However, the present invention is not limited to this. If the position code is such that the more digits in the code indicate a narrower area included in the area, for example, adopt a telephone number, latitude / longitude or postal code from the area code Can be.
[0058]
For example, if it is a telephone number, the area code can be used as the peripheral position code, and if it is latitude / longitude, the longitude data is fixed and only the latitude side is up to “degree”, up to “minute”, Each second can set a wide and narrow peripheral position code. It is also possible to use the reverse or both the latitude and longitude. Furthermore, in the case of a postal code, only the upper one digit, the upper two digits, the upper three digits, and the upper five digits can be adopted as the peripheral position codes.
