Next, the destination is set with the destination name such as area name, factory name, telephone number, address, registered location, road name, etc. (step S3), and the path from the current location to the destination is searched (step S4). When the route is determined, the route guidance/display is repeated until the vehicle reaches the destination, while the current position detector 2 tracks the current position (step S5). When the parking setting is entered before reaching the destination, the search area is set and re-search is performed in the search area, and the route guidance is repeated in the same manner until the vehicle reaches the destination.
 When searching for a place by inputting a phone number, setting the place and executing a guide on the map, according to the present invention, the location retrieval output system using the phone number judges that the user of the input phone number is such as a business owner. No restrictions are given. The user of the phone number, or the user of the phone number with given restrictions, such as private users. Then, if the user is a business owner, output information about the user's location (display, guide, and set a location), and if the user is a private user, under fixed conditions such as inputting the user's name Output information about the user's location. When the user is a business owner, the output of the information about the user’s location is to display the name of the business, such as stores, factories, etc., and when the user is a private user, the personal name or address is displayed, and then the user’s name or address is displayed. The location is the center of the map. Furthermore, the input of a place such as a destination or a route point is performed by inputting a place and setting the input place as a destination. The conditions required by the private user are, for example, input the user’s name and the user’s input name matches the user’s name of the phone number, so as to display, for example, the user’s phone number and name, and then display the user’s location as The center map can also set the location. If the user's name does not match, an alarm message will be output. In addition, when the user makes an input error, it can be handled by inputting the user's name or phone number again.
 image 3 To show an example of a data structure to be used in the location retrieval output system using a telephone number according to the present invention, and Figure 4 This is a diagram showing an example of a data structure divided into a town page and hello data.
 The data used in the location retrieval output system using phone numbers according to the present invention includes phone number data, Japanese syllable data, and location information data, such as image 3 Shown in. In addition, the phone number data is data in which the offset of the phone number and the location information data is stored. When the phone number is input, the location retrieval output system performs a search and obtains the offset based on the location information data of the phone number. Out the location information data. The location information data offset is used to show, for example, the storage address of the location information data. These phone number data and location information data are set as retrieval data, so that when a phone number is input, the location information data of the hit (matched) phone number is retrieved, and the location information data offset is based on Retrieve various information about the location from the location information data and display the retrieved information on a map. Japanese syllabic data is data in which the pronunciation of the user of the phone number or the place name is stored in Japanese syllables and together with the offset of the place information data, where the place search output system performs a search when the pronunciation or place name is input, and the The location information data is obtained on the basis of the location information data offset of the pronunciation or location name. Here, the name of the place is the name of the factory, the name of the individual, and so on.
 Location information data is information about the location of the phone user, such as location name, address, location coordinates (x, y), etc., stored in the order of telephone numbers or Japanese syllables, or stored by combining respective addresses and identification marks. data. When entering a phone number and the pronunciation or place name stored in the phone number data and Japanese syllable data, it is convenient to use the address to output confirmation information and give each level of the address a code, such as "Aichi-Prefecture" for 23 and "Okazaki" -City" is 202. In addition, the location coordinates are used, for example, to display a map centered on the location or to display the location by adding a mark on the map.
 An identification mark is set to classify users. For example, it classifies users into restricted users, that is, private users or non-restricted users, that is, users with the phone number of the business owner. Therefore, if according to the phone book, the data in one of the phone books, such as the name of the town page (the name of the registered trademark of NTT, hereinafter referred to as such) is the data of the business owners of factories, shops, enterprises, etc., so they are not restricted. The data in other phonebooks, such as the hello page (the name of NTT's registered trademark, which will be referred to hereafter), is data of private households, so they are restricted and a logo is set on them. However, this is undoubtedly For example, restricted or unrestricted identification information can be set on the basis of other classifications or divisions. If the phone number restriction is not given as described above, the location information is provided immediately, and if the phone number restriction is given, the user name is checked and the location information is provided based on the hit. In addition, when the addresses are displayed on the screen with letters, they can be constructed to convert from codes to letters using a separately stored address database.
 Figure 4 It is a set of block diagrams showing an example of dividing the above-mentioned telephone number data, Japanese syllabic data, and map information data into town page data without restriction settings and hello page data with restriction settings, respectively. In this case, there is no need to set the identification information for distinguishing the town page data or the hello page data set as the location information data. Therefore, when this data structure is adopted, the selection of the phone number used to enter the town page or the phone number in the hello page, that is, the input mode of entering a phone number that is not restricted or restricted, can constitute an input mode by selecting On the basis of determining the offset of the phone number to perform the search.
 The following describes an example of retrieval and guidance processing in the telephone number input mode using the above retrieval data. Figure 5 6 is a flowchart showing an example of search and guidance processing in the phone number input mode, and FIG. 6 is a flowchart showing an example of location setting processing in the phone number input mode.
 Such as Figure 5 As shown in, the phone number input mode first displays the phone number input screen (step S11). As the phone number is input, it is judged whether all the digits are input, that is, the 9 or 10 digit number according to the region (step S12) . If all the digits of the telephone number are not entered, it is judged whether the entered digits are as many as the local telephone exchange number (step S13). If the entered telephone number has different digits than the local telephone exchange number, The input is reset (step S14), for example, by notification with a beep and the process returns to the telephone number re-entry mode. If the input telephone number has as many digits as the local telephone exchange number, a representative place is retrieved and information about the place is output (step S17).
If all the digits of the phone number are entered, the phone number data is searched (step S15), and then it is judged whether the hit phone number is found (step S16). If the hit telephone number is not found, it searches for a representative place and outputs information about the place in the same way as inputting a telephone number with as many digits as the local telephone exchange number (step S17). If the hit phone number is found, then it is judged whether the hit phone number is a registered place (step S18), if it is a registered place, information about the registered place is output (step S19), and if it is not a registered place, then It is judged whether the user of the telephone number is a private user (step S20). In addition, judging whether to register a place can be performed by referring to a table of registered places (not shown in the figure) or an identification mark given information about the registered place.
 If the user is a business owner, the name or address of the factory is output (step S21). If the user is a private user, a screen showing Japanese syllables is displayed (step S22). The names of the users of the received phone numbers are compared, and then it is judged whether they match each other (step S23). If it matches the user's name, output the user's location information about the input phone number (step S25), and if it does not match the user's name, notify the user of the mismatch with a beep and output a message (step S24) . Regarding phone number input or Japanese syllable input, the applicant has made several suggestions, so the description is omitted (see, for example, Japanese Patent Publication Nos. Heisei 8-94377 and Heisei 9-97226 for reference).
 In addition, the location setting process by inputting the input number is described as follows: As shown in FIG. 6, when the phone number is input (step S31), it is judged whether the input number matches the phone number data (step S32). If it matches the telephone number data, it is further judged whether the matching number is found in the town page data (step S33), and if it is found in the town page data, the corresponding factory name and coordinates are obtained from the location information data (step S34). ), and display a map centered on the coordinates obtained by the factory name and set a location (step S35).
 If the entered phone number is not found in the town page data when the judgment is made in step S33, that is, it is found in the hello page data, and display, for example, "private home", "map near the local telephone exchange number" and "address table" "" etc. select the screen (step S36), and then it is judged whether "private family" is selected (step S37). If "Private Family" is selected, the personal name input screen is displayed (step S38), the personal name input process is executed (step S39), and it is judged whether the input phone number matches the personal name (step S40). If it does not match, return to step S36, and if it matches, obtain coordinates from the map coordinate data (step S41), display a map centered on the obtained coordinates, and set a place (step S42).
 If the entered telephone number does not match the telephone number data, the selection screens of "local telephone exchange number neighborhood map" and "address list" are displayed (step S43) and it is judged whether the "local telephone exchange number neighborhood map" ( Step S44). In addition, the judgment process is also executed when "Private Family" is not selected at step S37.
 If the "map near the local telephone exchange number" is selected in step S44, the representative coordinates of the local telephone exchange number of the input telephone number are obtained (step S45), and a map centered on the obtained coordinates is displayed and displayed on it. A place is set above (step S45). In addition, if the "address table" is selected, an address is selected in the address table (step S47), the coordinates of the selected address are obtained (step S48), and a map centered on the obtained coordinates is displayed and set on it. A place is determined (step S49).
 The present invention is further described on the basis of specific screens and examples of these screen changes. FIG. 7 is a diagram describing an embodiment of a screen change when setting a destination with a location, Figure 8 Example of input screen for phone number, Picture 9 To find an example of the selection screen to be displayed when the phone number is hit in the hello page, Picture 10 To illustrate an example of the selection screen to be displayed when no hitting phone number is found or as many phone number digits as the local telephone exchange number are entered, Picture 11 To show an example of a Japanese syllable screen, FIG. 12 is a diagram showing an example of a map display screen for displaying factory names, Figure 13 To show an example of a map display screen for displaying a private home, FIG. 14 is a diagram showing an example of a map display screen for displaying addresses of locations with precise positioning, and Figure 15 This is a diagram showing a nearby map display screen that displays a nearby map on the basis of representative coordinates.
 In the phone number input mode, display Figure 8 Enter the phone number shown in the screen. The phone number input screen is divided into corresponding areas, which include a message area, an input display area, and a keyboard input area. In the message area, "Use the 10-key numeric keypad on the remote control to enter the number" is displayed, and the entered phone number "0527011111" is displayed in the input display area, and the 10-key numeric keypad is used to enter the number, and the return key is used to return. To the previous screen or mode, the backup key is used to back up the numbers and re-enter when incorrectly entered, and the search key is used to start the search of the entered number sequence when setting and displaying the phone number. In this screen, when you use the 10-key numeric keypad to enter a number and enter the search key, the search starts, depending on whether the entered number is 9 or 10 digits, or if they have as many digits as the local telephone exchange number (As shown in Figure 7) and move to the following steps.
 When entering a 9 or 10 digit number, the following processing is performed according to whether the hitting phone number is found in any of the registration location, town page, and hello page, or no hitting phone number is found. As shown in Figure 7, if a hit is found in the registered place, use the registered place name to set the destination and change the phone number input screen to the destination map display. If the hit is found in the town page, use Make the destination setting for the factory name and change the screen to the destination map display screen shown in Figure 12. If you want to find the hit in the hello page, change the screen to Picture 9 Select the screen shown in and if no hit is found, change the screen to Picture 10 The selection screen shown in. In addition, if the entered number has as many digits as the local telephone exchange number, change the screen to Picture 10 If you do not enter as many digits as the local telephone exchange number, output a beep and reset input, and then return to Figure 8 The phone number input screen shown in the processing.
 What to display when a hit is found in the hello page Picture 9 The selection screen shown in is to choose whether to display the map of the private home, the nearby map of the local telephone exchange number (052-701), or because the phone number is the phone number of the private user who is restricted from providing information. Select the screen of the address map of the address. At this stage, I chose "Private Family" and the screen changed to Picture 11 The Japanese syllable input screen shown in. If you enter the last name, full name, or first letter of the user’s name in Japanese syllables on the Japanese syllable screen, such as Figure 13 The match between the phone number and the user's name is judged as shown in, and an accurately positioned location is displayed on the map with the phone number, user's name and address according to this match. Therefore, when "Go to this place" is selected, the destination is determined. However, if it does not match the phone number user, after displaying a message such as "The phone number entered does not match the user", return to Picture 9 The processing in the selection screen shown in.
 In addition, if Picture 9 "052-701 Nearby Map" is selected in the selection screen shown in and the screen changes to Figure 16 The map display screen near the local telephone exchange number shown in the figure, and if the "Address List" is selected, the screen will change to the map display screen shown in Figure 14, where available include counties, cities, towns, villages, Set the destination by number, 00aza (large village selection), Koaza (small village selection), group number and other addresses. By selecting "Nearby Map" or "Address List", the screen change is related to Picture 10 The screen changes made by the selection screen shown in are the same.
 Figure 16 To show an example of the same family surname table displayed if a hit is found in a private family, Figure 17 To show an example of a table of neighboring private households, Figure 18 For show in Figure 17 A diagram showing an example when the distance and direction from a specific place are added to the table shown in FIG. 19 is a flowchart describing an example of processing when the table of the same family surname is output, and Figure 20 This is a flowchart describing an example of processing when a neighboring private home is output.
 According to the above mode, when the search is performed by entering a phone number, if the user of the phone number is restricted, enter the user name, first letter, or last name, and enter between the entered item and the user of the entered phone number Based on the matching, the user’s location of the entered phone number is displayed on a map with small locations. However, in this case, it can be performed by displaying a table and inputting specified items from the table instead of Japanese syllable input . For example, when a user’s name is entered, search nearby Figure 16 Similar names or the same surnames shown in and displayed in the table, and if a user name that is different from the user's name entered with the entered phone number is specified, mismatch processing is performed. Therefore, if multiple items cannot be retrieved in a certain area, the area can be gradually expanded from Koaza→ooaza→city→town→village→county→or from Koaza→centered on the location of the corresponding phone number user Adjacent Koaza in a circle, rectangle, or polygon.
 In addition, if the phone number input finds a hit in private households, multiple private households near the hit private household can be retrieved, and their table can be displayed, such as Figure 17 Shown in. In addition, you can display a table of distance and direction from a specific place, such as Figure 18 Shown in. Of course, in addition to the table, the corresponding location can be displayed on the map. When a hit is found in a private family, the address, the first letter of the name, the first letter, the zip code, etc. can be used as specific information to find the name of the private family, because the purpose of specifying the user’s specific information is to remove The user’s phone number is restricted and entered, so that a match between specific information and the user is used to provide specific information. The adjacent search area may be based on a simple distance from a hit private home or a distance from a hit private home in a town.
 When the table of the same surname is output as above, and the phone number is input as shown in FIG. 19 (step S51), the process is executed to obtain the personal name corresponding to the input phone number from the location information data (step S52), which is used as the search area In the same small village area, the personal name of the same surname as the obtained personal name is searched (step S53). It is judged whether multiple personal names are retrieved (step S54). If multiple personal names are not retrieved, the search area is changed until multiple names are retrieved (step S55), and their names are displayed when multiple personal names are retrieved. Table (step S56). Then, it is judged whether a personal name is selected from the table (step S57), and it is further judged whether the user of the input telephone number matches the selected personal name (step S58). If it does not match, return to step S51 to enter the phone number again, and if it matches, obtain the coordinates from the location information data (step S59), display a map centered on the obtained coordinates (step S60), and complete the location setting deal with. In addition, if there is no match, processing can return to Picture 9 The selection screen shown in.
 For example, the processing executed when the table of neighboring private households is output, the phone number is input (step S61), the coordinates corresponding to the input phone number are acquired (step S62), and the coordinates are calculated from the acquired coordinates to the predetermined area The distance of the location coordinates of other private households (step S63), and the list of private households is displayed in the order of the most moment distance (step S64). Then, it is judged whether a personal name is selected from the list (step S65), and it is further judged whether the user of the input telephone number matches the selected personal name (step S66). If it does not match, return to step S61 to input the telephone number again, and if it matches, obtain the coordinates from the location information data (step S68) and complete the location setting process. In addition, if there is no match, processing can return to Picture 9 The selection screen shown in.
 The present invention is not limited to the above-mentioned embodiment, and various changes can be made. For example, in the above embodiment, the phone number and pronunciation or location name, address, location coordinates, and identification information are stored as location information data. If the user owns a store, then specific information such as the content and type of the company can be stored, or The guide information can be stored separately and the offset information of the guide information can be stored in the location information data. In addition, the identification information is stored in the location information data, but it can also be stored in the phone number data or users can be divided into several categories such as private, registered, public facilities, shops, etc. and set the identification information according to the classification. constitute.
 In addition, it is described that the full name, last name, or first letter is input using Japanese syllables when inputting the user's name. However, needless to say, if any information that can describe the user together with the phone number of a private home can be used as specific information for the user, that is, various information that can be checked with the information retrieved by the phone number, such as name , Chinese characters (Chinese characters), Roman alphabet, initials, first name, middle name, last name, address, county, state name, city name, town name, street name, postal code, gender, blood type, date of birth, company, school, E-mail address (full address including @), identification number, etc.
 In addition, according to the present invention, the entered telephone number is retrieved in the telephone number digits and the user name of the entered telephone number is checked whether the user is a private user. Therefore, the identification information can be stored in the telephone number data, if the user is a private user. The user can store the specific information of the private user together with the identification information in the phone number data. In this way, it is immediately possible to identify whether the user is a private user. Furthermore, when the user's name is required to be verified, it can be verified by searching only in the phone number data. In addition, Japanese syllable data can be used as factory name retrieval data. The official name and general name or (military name are stored in pronunciation data respectively, such as "Nagoya Tetsudo" and "Kanku" (Kansai International Airport), which can be retrieved by entering any name.
 As is obvious from the above description, according to the present invention, the location retrieval output system for retrieving and outputting information about the location of the user corresponding to the phone number by the phone number includes a storage device for storing specific information describing at least one phone number and the user And information about the user’s location; an input device for inputting specific information describing the phone number or user; a retrieval device for retrieving information about the user on the basis of the phone number input by the input device and specific information describing the user Information about the location of the user; and an output control device for controlling the output of the information about the location of the user retrieved by the retrieval device based on the input phone number and specific information describing the user. Therefore, if the input is Wrong phone number, it is no longer a problem to display a location different from the location requested by the guide and the user. In addition, when the information about the location of the user is displayed, the user is relieved about whether the user can travel to the desired location. Location and confirmation that the information is believed to be correct. In addition, if the phone number user is a private user, and the information is not disclosed to the public, he is different from the business owner of a company, store, factory, etc., therefore, the search is performed automatically and unconditionally from the entered private phone number and the privacy The viewpoint does not consider whether they are willing to output personal information about them. However, the present invention judges whether the input phone number matches the specific information describing the user, and controls the output of personal information about them if they match, thereby solving the privacy problem.
