Are known. Among such navigation devices, there is known a device capable of transferring registered location data to another navigation device using a non-volatile storage medium such as a memory card (Patent Document 1).

JP-A-11-83527

  In the navigation device disclosed in Patent Document 1, for example, when the map data is upgraded by exchanging the navigation device from an old one to a new one, the contents of the map data change before and after the transfer of registered location data. There may be. Therefore, if the registered facility is lost or moved, the facility corresponding to the registered location does not exist in the map data after the registered location data is transferred.

According to the first aspect of the present invention, in-vehicle information terminal for inputting registered location data relating to each registered location registered in advance via a connected relay means reads facility data relating to various facilities recorded in advance. Means, a comparison means for comparing the inputted registration place data with the facility data read by the facility data reading means, and a registration place data inputted based on a comparison result between the registration place data and the facility data by the comparison means. Update means for updating the storage device, and storage means for storing the registration place data updated by the update means.
According to a second aspect of the present invention, in the in-vehicle information terminal of the first aspect, the registered place data represents one or both of registered place position information indicating the position of each registered place and the name or telephone number of each registered place. The facility data includes at least facility location information representing the location of each facility, and facility identification information representing one or both of the name and / or telephone number of each facility, and is based on comparison means. Based on the comparison result between the registered location data and the facility data, for each registered location corresponding to the facility, the first determination means for determining whether the contents of the registered location position information and the facility location information match, and comparison 2nd which judges whether the contents of registration place specific information and facility specific information correspond about each of the registration place applicable to facilities based on the comparison result of registration place data and facility data by means Anda judging means, updating means is based on the determination result by the first determination unit and the second judging means, and updates the input registered place data.

If it is determined to be a denial, the registered location data is not updated.

  According to the present invention, the registered place data can be updated in accordance with the map data after the registered place data is transferred.

  A configuration of a navigation apparatus according to an embodiment of the present invention is shown in FIG. The navigation device 1 and the navigation device 2 have the same configuration, and the registered location data is transferred via the memory card 3 by replacing the memory card 3 which is a nonvolatile general-purpose storage medium. Can be replaced. Below, the structure of the navigation apparatus 1 is demonstrated and since the navigation apparatus 2 is the same structure, description is abbreviate | omitted.

  The navigation device 1 includes a memory card slot 10, a control circuit 11, a ROM 12, a RAM 13, a current location detection device 14, a flash memory 15, a display monitor 16, an input device 17, and a disk drive 18. A memory card 3 is loaded in the memory card slot 10. The disc drive 18 is loaded with a DVD-ROM 19 in which map data is recorded.

  The control circuit 11 includes a microprocessor and its peripheral circuits, and performs various processes and controls by executing a control program stored in the ROM 12 using the RAM 13 as a work area. In this control circuit 11, various processes such as a search process for a recommended route to a set destination are performed based on the map data recorded on the DVD-ROM 19.

  The current location detection device 14 is a device that detects the current location of the host vehicle. For example, a vibration gyro 14a that detects the traveling direction of the host vehicle, a vehicle speed sensor 14b that detects a vehicle speed, and a GPS sensor that detects a GPS signal from a GPS satellite. 14c and the like. The navigation device 1 can determine a route search start point when searching for a recommended route based on the current location of the host vehicle detected by the current location detection device 14.

  The flash memory 15 is a nonvolatile memory that can retain the stored contents even when the navigation device 1 is powered off. The flash memory 15 stores registered location data registered by the user. The user can designate a specific point on the map and register the point as a registered place in advance. The name of each registered place is automatically given a corresponding place name or facility name based on the map data, but the user can also give an arbitrary name such as “home”.

  The registered location data stored in the flash memory 15 can be called up at the time of setting the destination by the user's operation, and any registered location can be selected as the destination. As will be described later, when the map data is read from the hard disk instead of the DVD-ROM 19, the registered location data may be recorded on the hard disk without using the flash memory 15.

  The display monitor 16 displays various images such as a map image using image data created by the control circuit 11 based on the map data recorded on the DVD-ROM 19. The input device 17 has various input switches for the user to perform various operation inputs such as registration location setting and destination setting for searching for a recommended route. The input device 17 is realized by an operation panel, a remote controller, or the like. The user can cause the navigation device 1 to execute various processes by appropriately operating the input device 17 in accordance with a screen instruction displayed on the display monitor 16.

  The disk drive 18 reads map data from the loaded DVD-ROM 19. Map data includes route calculation data used for route search to the destination, route guidance data used to guide the vehicle to the destination according to the recommended route, such as intersection name and road name, and road data representing the road. Etc. are included. The map data also includes background data representing map shapes other than roads, such as various facilities, rivers, and railways. Furthermore, the facility data representing the location and name of various facilities, telephone numbers, facility types, and the like are also included in the map data.

  In the road data, the minimum unit representing a road section is called a link, and each road is composed of a plurality of links. A point connecting the links is called a node, and each node has position information (coordinate information). The link shape, that is, the shape of the road is determined based on the position information of the node. Although an example using a DVD-ROM is described here, the map data may be read from a recording medium other than the DVD-ROM, such as a CD-ROM or a hard disk.

  When the user operates the input device 17 to set the destination, the navigation device 1 uses the current location detected by the current location detection device 14 as a route search start point and calculates a predetermined algorithm based on the above-described route calculation data. By doing so, a route search from the present location to the destination is performed. The recommended route obtained as a result of the route search is displayed on the map separately from other roads by changing its display form, for example, display color. Thus, the user can recognize the recommended route on the map displayed on the display monitor 16. In addition, the navigation device 1 guides the host vehicle by instructing the traveling direction by an image or voice to the user so that the host vehicle can travel according to the recommended route. In this way, route guidance to the destination is performed by guiding the host vehicle to the destination according to the recommended route displayed on the map.

  FIG. 2 is an example of registered location data stored in the flash memory 15. Here, an example is shown in which a total of six registered place data of “home”, “T dome”, “O dome”, “D land”, “S land”, and “M hospital” are recorded. As shown in FIG. 2, the registered place data includes a name of each registered place, a coordinate value representing the position of each registered place on the map, a group number (Gr) representing the type of each registered place, and each registered place. The phone number is recorded. If the registered location corresponds to any facility, the contents of the registered location data can be automatically determined based on the facility data included in the map data.

  When setting a destination from a registered location, a list of registered locations is displayed first, and when any registered location is selected from the list, the location of the registered location is displayed. Thereafter, the user selects whether or not to set the selected destination as a registered location.

  When the memory card 3 is loaded into the memory card slot 10, the navigation device 1 and the memory card 3 are connected. In this state, when a predetermined menu operation is performed by the user using the input device 17, the registration place data in FIG. 2 is recorded in the memory card 3. Recording the registered location data in the flash memory 15 in the memory card 3 in order to transfer the registered location data from the navigation device 1 to the navigation device 2 in this way is called “export”.

  After the registered location data is recorded in the memory card 3, when the user replaces the memory card 3 from the navigation device 1 to the navigation device 2, the exported registered location data in FIG. 2 is taken into the navigation device 2. Reading the registered location data thus exported from the memory card 3 and importing it into the navigation device 2 is called “import”. The imported registered location data is stored in the flash memory 25 of the navigation device 2. In this way, the registered location data is transferred from the navigation device 1 to the navigation device 2.

  When the registered location data is imported in the navigation device 2, the registered location data is compared with the facility data in the map data recorded on the DVD-ROM 29 to compare the data contents of the two. At this time, only a registered place (hereinafter referred to as a registered facility) represented as a certain facility in the facility data is set as a comparison target. Registration sites that do not fall under registered facilities cannot be compared. In the example of the registered place data in FIG. 2, the data contents of the registered places of “T Dome”, “O Dome”, “D Land”, “S Land”, and “M Hospital” among the registered places are as follows. Compared with facility data. However, “home” that does not correspond to a registered facility is not compared with facility data.

  As a result of comparing the data contents of both, if the registered place data and the contents of the facility data do not match for any registered facility, the contents of the registered place data of the registered facility are updated according to the facility data. By doing in this way, the registration place data imported into the navigation apparatus 2 can be made into the correct content based on facility data. For example, the facility existing in the facility data of the navigation device 1 may disappear in the facility data of the navigation device 2 or may be transferred to a different location due to version upgrade of the map data. When such a facility is registered as a registered facility in the navigation device 1, when the registered location data is imported into the navigation device 2, the content of the registered location data is updated in accordance with the facility data of the navigation device 2. The

  As described above, when the contents of the registered place data are updated in accordance with the facility data in the navigation device 2, various screens are displayed according to the comparison result between the registered place data and the facility data for each registered facility. 26. Examples thereof are shown in FIGS.

  FIG. 3 is an example of a screen displayed when the registered facility name and the telephone number match in the registered place data and the facility data, but the coordinate points do not match, that is, when the registered facility is moved. Hereinafter, such a screen is referred to as a “position change screen”. Here, the position change screen displayed about "M hospital" among the registration facilities of FIG. 2 is shown. The registered land data content before update is displayed on the upper left side of the screen, and the updated registered land data content is displayed on the lower left side of the screen. At this time, it is possible to make it easy for the user to understand the non-matching portion, that is, by displaying only the coordinate values in a different display form. For example, it is possible to change the color and thickness of characters, or to blink the characters. The same applies to the screen examples described below.

  On the right side of the position change screen in FIG. 3, the positions of the registered facilities before and after the update are displayed on the map, respectively. The mark indicated by reference numeral 31 represents the position of the registered facility before update, and the mark indicated by reference numeral 32 represents the position of the registered facility after update. When this screen is displayed, a map scale that can display both the mark 31 and the mark 32 on the map at the same time is automatically set in the navigation device 2. Or it is good also as dividing a screen into two and displaying the mark 31 and the mark 32 separately on each.

  After the position change screen of FIG. 3 is displayed, a screen as shown in FIG. 4 is displayed. On this screen, the user is notified that the registered facility location of the imported registered location data is different from the location of the facility data of the navigation device 2 and the user selects whether to update the contents of the imported registered location data Let When the user selects the button 41 with “Yes” written by operating the input device 27, the contents of the registered place data are updated in accordance with the facility data for the registered facility and stored in the flash memory 25. . When the user selects the button 42 written “No”, the registered location data is not updated as it is, but is stored in the flash memory 25.

  FIG. 5 is an example of a screen that is displayed when the registered facility coordinate point matches the registered location data and the facility data, but the name and the telephone number do not match, that is, when the registered facility is changed. Hereinafter, such a screen is referred to as a “facility change screen”. On the right side of this facility change screen, the positions of the registered facilities before and after the update are displayed at the same position by marks 31.

  After the facility change screen of FIG. 5 is displayed, a screen as shown in FIG. 6 is displayed. On this screen, the user is notified that the registered facility of the imported registered land data is different from the facility data of the navigation device 2 and the user is asked whether to update the contents of the imported registered land data. Let Similar to the screen of FIG. 4, when the button 41 written “Yes” is selected, the contents of the registered location data are updated in accordance with the facility data for the registered facility and stored in the flash memory 25. When the button 42 written “No” is selected, the registered location data is stored in the flash memory 25 without being updated.

  FIG. 7 is an example of a screen displayed when there is no facility that matches the registered facility. If none of the coordinate points, names, and telephone numbers of the registered facilities match in the registered place data and the facility data, it is determined that there is no matching registered facility. Hereinafter, such a screen is referred to as a “screen without corresponding facility”. The position of the registered facility before the update is displayed by a mark 31 on the right side of the no facility screen.

  After the screen without corresponding facility in FIG. 7 is displayed, a screen as shown in FIG. 8 is displayed. In this screen, the user is notified that the facility corresponding to the registered facility of the imported registered location data is not already in the facility data of the navigation device 2, and whether or not the content of the imported registered location data is to be updated. Let the user select When the button 41 written as “Yes” is selected, the registered location data for the registered facility is deleted, so that the content of the registered location data is deleted according to the facility data and stored in the flash memory 25. Let If the button 42 written “No” is selected, the registered location data is stored in the flash memory 25 without being deleted.

  In addition, when the coordinate point of the registered facility is different between the registered location data and the facility data, and only one of the name and the telephone number matches, it is determined that there is no matching registered facility and there is no corresponding facility in FIG. The screen may be displayed, or the location change screen of FIG. 3 may be displayed by determining that the registered facility has been moved. In addition, if the coordinate point of the registered facility is the same in the registered location data and the facility data and either the name or the telephone number is different, it may be determined that they are the same registered facility, or The facility change screen of FIG. 5 may be displayed by determining that the registered facility is different.

  In the above description, the determination result can be changed depending on whether the name matches the telephone number. For example, if there is a facility that only has the same name as the registered facility but has a different phone number and coordinate point, it will be judged as a different facility, and the no facility screen will be displayed. If there is a facility with a different phone number and name, it is determined that they are the same facility, and a position change screen is displayed. Furthermore, it may be determined which screen is displayed in consideration of the group number in the registration place data and the facility data, the positional relationship between the coordinate points, and the like.

  As described above, FIG. 9 shows a flowchart executed when the registered location data is updated in the navigation device 2 in accordance with the facility data and the registered location data is imported. This flowchart is executed by the control circuit 21 when the memory card 3 in which the registration place data exported from the navigation device 1 is recorded is loaded in the memory card slot 20.

  In step S <b> 10, the registered location data exported from the navigation device 1 and recorded in the memory card 3 is read from the memory card 3. Thereby, the registered place data is input to the navigation device 2. In the next step S20, one of the registered facilities is selected in the registered place data input in step S10. In step S30, the registration place data input in step S10 is compared with the facility data in the map data recorded on the DVD-ROM 29 and read by the disk drive 28.

  In step S40, based on the comparison result in step S30, it is determined whether or not the coordinates of the selected registered facility match in the registered place data and the facility data. If they do not match, the process proceeds to step S50, and if they match, the process proceeds to step S60.

  In step S50, based on the comparison result in step S30, it is determined whether or not the name and telephone number of the selected registered facility match in the registered place data and the facility data. If not, the process proceeds to step S70. This corresponds to a case where there is no facility in the facility data that matches the selected registered facility. On the other hand, if the name and telephone number of the selected registered facility match in the registered place data and the facility data, the process proceeds to step S100. This corresponds to the case where the registered facility is moved.

  In step S60, as in step S50, based on the comparison result in step S30, it is determined whether or not the name and telephone number of the selected registered facility match in the registered location data and the facility data. If not, the process proceeds to step S130. This corresponds to a case where the registered facility is changed. On the other hand, if the name and telephone number of the selected registered facility match in the registered place data and the facility data, that is, if the registered place data and the contents of the facility data all match, the process proceeds to step S160.

  When the process proceeds to step S70, in step S70, the corresponding facility-less screen of FIG. Further, the screen of FIG. 8 is displayed. In step S80, it is determined whether or not the user confirmation result is OK according to the user's operation input on the screen of FIG. That is, when the button 41 is pressed by the operation of the input device 27, it is determined that the user confirmation result is OK (positive), and the process proceeds to step S90. On the other hand, if the button 42 is pressed, it is determined that the user confirmation result is not OK (denial), and the process proceeds to step S160 without executing step S90.

  In step S90, the data content relating to the selected registered facility is deleted from the registered place data read in step S10. Thereby, the content of the registration place data is updated according to the facility data for the registered facility. If step S90 is performed, it will progress to step S160.

  When the process proceeds to step S100, the position change screen of FIG. 3 is displayed on the display monitor 26 in step S100. Subsequently, the screen of FIG. 4 is displayed. In step S110, it is determined whether or not the user confirmation result is OK in response to a user operation input on the screen of FIG. When the button 41 is pressed, it is determined that the user confirmation result is OK (affirmation), and the process proceeds to step S120. If the button 42 is pressed, it is determined that the user confirmation result is not OK (denial), and the process proceeds to step S160 without executing step S120.

  In step S120, the coordinate value of the registered facility selected from the registered place data read in step S10 is corrected according to the content of the facility data in the map data. Thereby, the contents of the registered place data are updated in accordance with the facility data. If step S120 is performed, it will progress to step S160.

  When the process proceeds to step S130, the facility change screen of FIG. 5 is displayed on the display monitor 26 in step S130. Further, the screen of FIG. 6 is displayed. In step S140, it is determined whether or not the user confirmation result is OK in response to a user operation input on the screen of FIG. If the button 41 is pressed, it is determined that the user confirmation result is OK (affirmation), and the process proceeds to step S150. If the button 42 is pressed, it is determined that the user confirmation result is not OK, and the process proceeds to step S160 without executing step S150.

  In step S150, the name and telephone number of the registered facility selected from the registered location data read out in step S10 are corrected according to the facility data content in the map data. Thereby, the contents of the registered place data are updated in accordance with the facility data. If step S150 is performed, it will progress to step S160.

  In step S160, it is determined whether all registered facilities included in the registered place data read in step S10 have been selected in step S20. If all the registered facilities have been selected, the process proceeds to step S170, and the registered place data is written in the flash memory 25. The registered location data thus written is stored in the flash memory 25. If step S170 is performed, the flowchart of FIG. 9 will be complete | finished. In this way, the registered place data is updated in accordance with the facility data and imported into the navigation device 2. On the other hand, if there is a registered facility that has not yet been selected, the process returns to step S20. In step S20, one of the unselected registered facilities is selected, and then the processing described above is repeated.

According to the embodiment described above, the following operational effects are obtained.
(1) In the state where the memory card 3 is loaded in the memory card slot 20 and the navigation device 2 and the memory card 3 are connected, the registered location data registered in advance by the user in the navigation device 1 is transferred via the memory card 3. input. Then, the inputted registration place data is compared with the facility data in the map data read from the DVD-ROM 29 by the disk drive 28 (step S30). Based on the comparison result, the input registration place data is updated by any one of the processing steps of steps S90, S120, and S150. The updated registration location data is written and stored in the flash memory 25 (step S170). Since it did in this way, registration place data can be updated according to the map data of the navigation apparatus 2 after transferring registration place data.

(2) Based on the comparison result between the registration place data and the facility data in step S30, it is determined whether or not the coordinates match for each of the registration places corresponding to the facility (step S40), and the name and telephone number are determined. It is determined whether or not they match (steps S50 and S60). Based on these determination results, any one of the processing steps of Steps S90, S120, and S150 is executed, and the input registration place data is updated. Since it did in this way, according to the comparison result of registration place data and facility data, registration place data can be updated by an appropriate method.

(3) If it is determined in step S40 that the coordinates do not match, and in step S50 it is determined that the name and the telephone number match, the coordinate value of the registered facility is corrected according to the facility data (step S120). Therefore, it was decided to update the input registration location data. Since it did in this way, when a registration facility is moved, registration place data can be updated correctly.

(4) If it is determined in step S40 that the coordinates match, and if it is determined in step S60 that the name and telephone number do not match, the name and telephone number of the registered facility are corrected in accordance with the facility data (step S150). Therefore, it was decided to update the input registration place data. Since it did in this way, when a registration facility is changed, registration place data can be updated correctly.

(5) If it is determined in step S40 that the coordinates do not match, and in step S50 it is determined that the name and the telephone number do not match, the registration place data relating to the registered facility is deleted (step S90) and input. It was decided to update the registered location data. Since it did in this way, when the plant | facility which corresponds to a registration plant | facility does not exist in plant | facility data, registration place data can be updated correctly.

(6) Before updating the registered place data input in any of the processing steps of steps S90, S120, or S150, display any of the no facility screen, the location change screen, or the facility change screen indicating the update contents. The information is displayed on the monitor 26 (steps S70, S100, S130). Then, it is determined whether the user's confirmation result is affirmative or negative (steps S80, S110, S140). If it is determined affirmative, steps S90, S120, or S150 are executed to register the registered location. Update the data. If it is determined to be a denial, the registration location data is not updated without executing steps S90, S120, or S150. Since it did in this way, before updating registration place data, the user can confirm the update content, Furthermore, it can update only when a user desires, and it cannot update when not wishing.

  In the above embodiment, the coordinate point, name, and telephone number of each registered location are recorded in the registered location data, and the coordinate point, name, and telephone number of each facility are recorded in the facility data. Thus, an example of comparing the coordinate points, names, and telephone numbers of each registered facility has been described. However, the registration place data and the facility data may not include all of these information. Alternatively, information other than these may be included. That is, arbitrary information can be included in the registration place data and the facility data for comparison.

  Further, only one of the information and the name and the telephone number can be recorded and compared. That is, the registration location data includes a coordinate point (registration location location information) for representing the location of each registration location and either or both of a name and a telephone number for specifying each registration location (registration location specification information). The facility data includes a coordinate point (facility location information) for representing the location of each facility and either or both of a name and a telephone number for identifying each facility (facility identification information). It can be. Then, it is determined in step S40 of FIG. 9 whether or not the registered location position information matches the contents of the facility location information, and whether or not the registered location specifying information matches the contents of the facility specifying information in step S50 or S60. judge.

  In the above-described embodiment, an example in which registered location data is transferred via the memory card 3 has been described. However, registered location data may be transferred via other devices. For example, the navigation device 1 and the navigation device 2 may be connected by a cable, and registered place data may be transferred via the cable. Alternatively, a personal computer may be connected between the navigation device 1 and the navigation device 2, and the registered location data may be transferred via the personal computer.
