  According to the present invention, even if the user does not register when the registered place data is transferred, the facility that matches the user's preference can be set as the registered place.

  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 before transfer stored in the flash memory 15. Here, an example is shown in which registered place data of a total of six locations of “home”, “T dome”, “A ramen”, “B ramen”, “C ramen”, and “D ramen” is 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 a genre number. Has been. The group number represents a group (major classification) to which each registered place belongs, such as an entertainment facility and a restaurant. The genre number represents a genre (small classification) in a group of each registered place such as a ramen shop for restaurants, a family restaurant, and the like. Among the above registered locations, “A ramen”, “B ramen”, “C ramen” and “D ramen” are all ramen stores, and therefore have a common group number and genre number. 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, a new registered location that reflects the user's preference is automatically added based on the contents of the exported registered location data. That is, in the exported registered location data, if a predetermined number or more of the same type of facilities are registered as registered locations, the facility data relating to the same type of facilities as the registered locations (hereinafter referred to as the same type registered facilities) is DVD. -It is extracted from the facility data in the map data recorded in the ROM 29. When the facility data thus extracted is added to the registered place data when imported, a new registered place is added.

  FIG. 3 shows the contents of the registered location data after the navigation device 1 is transferred to the navigation device 2. In this registered place data, a total of eight registered places are recorded by adding “X ramen” and “Y ramen” to each registered place in the registered place data before transfer shown in FIG. “X Ramen” and “Y Ramen” newly added as registered locations are the registered locations of “A Ramen”, “B Ramen”, “C Ramen”, and “D Ramen” that fall under the same type of registered facility. Is the same type of facility, namely a ramen shop. The registered location data having such contents is recorded in the flash memory 25.

  FIG. 4 shows an example of a screen displayed when the destination is selected from each registered place in the registered place data in the navigation device 2 in which the registered place data shown in FIG. 3 is recorded. Here, registered locations that are ramen shops are displayed in a list, and the user is allowed to select a destination from the list. In this screen, as described above, display marks as indicated by reference numerals 31 and 32 are used for “X ramen” and “Y ramen” which are newly added registration locations reflecting the user's preference. Thus, the list is displayed in a display form different from other registered locations. This allows the user to distinguish from other registered locations. It should be noted that by using a display method other than this, the added registered location and other registered locations may be displayed in a distinguishable manner. For example, when each registered place is displayed in a list, it may be possible to distinguish between the two by changing the display form such as the color or pattern for the character or display frame. Or it is good also as distinguishing by making both call from another menu.

  Here, when the registered place data is imported in the navigation device 2, an extraction area for extracting a newly added registered place from the facility data will be described. As described above, if there is a registered place corresponding to the same kind of registered facility in the exported registered place data, the facility data is extracted from the map data recorded on the DVD-ROM 29 for the same kind of facility as that kind of registered facility. The At this time, one of the extraction areas as shown in FIG. 5, 6 or 7 described below is set based on the position of each of the same type registered facilities, and the same type of facility as the same type registered facility in the extracted area The facility data for is extracted.

  The extraction area shown in FIG. 5 is set as an area surrounded by each position of the same type registration facility. That is, if the same type of registered facilities “A ramen”, “B ramen”, “C ramen” and “D ramen” are in the positional relationship as shown in FIG. The area 40 is set as an extraction area on the map. In this extraction area 40, facility data relating to “X ramen” and “Y ramen” corresponding to the same type of facility as the same type registered facility, that is, a ramen shop, is extracted. By doing in this way, the facility of the area where a user often uses can be added to a registration place.

  The extraction area shown in FIG. 6 is set around the same type of registered facility located away from the home. That is, among the registered facilities of the same type, “A ramen” and “B ramen” are located in the area 41 centered on the home, and “C ramen” and “D ramen” are located at a predetermined distance or more away from the home. Therefore, it is assumed that the positional relationship is as shown in FIG. In this case, the extraction area 42 is set around “C ramen” and “D ramen”. For example, a circular area having a radius of a predetermined distance centered on an intermediate point between “C ramen” and “D ramen” is set on the map as the extraction area 42. In the extraction area 42 set in this way, facility data relating to “X ramen” and “Y ramen” corresponding to the same type of facility as the same type registered facility, that is, a ramen shop, is extracted. By doing in this way, the facility in the area away from the user's living area, for example, the frequently visited destination facility, etc. can be added to the registered place. Here, the region 41 is set around the home, but the region 41 may be set around another point, for example, an intermediate point between “A ramen” and “B ramen”.

  The extraction area shown in FIG. 7 is set around a road where similar type registered facilities are lined up. That is, roads 43 extend along the positions of the same type of registered facilities “A ramen”, “B ramen”, “C ramen”, and “D ramen”, and each has a positional relationship as shown in FIG. If so, an area within a predetermined range from the road 43 is set as an extraction area on the map. In this extraction area, facility data relating to “X ramen” and “Y ramen” corresponding to the same type of facility as the same type registered facility, that is, a ramen shop, is extracted. By doing in this way, the facility located along the same road as the same kind registration facility already registered can be added to a registration place.

  When the registered place data is imported, one of the extraction areas in FIGS. 5 to 7 as described above is set in the navigation device 2. The type of extraction area set at this time can be changed according to the situation. For example, when all of the registered facilities of the same type exist within a predetermined distance range, an extraction area as shown in FIG. 5 is set, and when any of the registered facilities does not exist within a predetermined distance, as shown in FIG. 6 or FIG. Set the extraction area. At this time, if the same kind of registered facilities are divided into those that are located near the home and those that are not so, an extraction area as shown in FIG. 6 is set, and if they are aligned along the same road, the extraction area as shown in FIG. Set. In this way, an optimal extraction area can be set according to the situation. If neither case applies, an arbitrary range, for example, a range within a predetermined distance around the home may be set as the extraction area, or the user may select the extraction area setting method. Also good.

  As described above, in the navigation device 2, the registration location data is imported by adding a new registration location reflecting the user's preference. A flowchart executed at this time is shown in FIG. 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, it is determined whether or not a predetermined number or more of the same type of facility, that is, a facility having the same group number and genre number as described above, is registered in the registered location data read in step S10. If it is determined that it is registered, the process proceeds to step S30. If it is determined that it is not registered, the process proceeds to step S80.

  In step S30, the registration sites corresponding to the same type of facilities determined to be registered in the predetermined number or more in step S20 are selected as the above-mentioned same type registered facilities. In the next step S40, the target facility type for newly adding a registered place is determined by the facility type specified by the group number and the genre number common to the same type registered facility selected in step S30. By determining the target facility type in this way, an extraction condition for extracting facility data in step S60 described later is set.

  In step S50, an extraction area is set on the map based on the respective positions of the same type registered facility selected in step S30. This extraction area is set using any of the methods described with reference to FIGS. In step S60, the facility data of the facility additionally registered as a new registration location is extracted from the map data recorded on the DVD-ROM 29. At this time, the facility data is extracted for the facility of the same type as the target facility type determined in step S40 in the extraction area set in step S50. Thereby, the facility data regarding the facility of the same type as the registered facility of the same type selected in step S30 is extracted.

  In step S70, the facility data extracted in step S60 is added to the registered place data read in step S10. Thereby, a new registration place is added. In step S80, the registered location data is written into the flash memory 25. The registered location data thus written is stored in the flash memory 25. If it is determined in step S20 that a predetermined number or more of the same type of facilities are not registered, that is, if there is no same type of registered facility, the registered location data read in step S10 is written in the flash memory 25 as it is. . When step S80 is executed, the flowchart of FIG. 8 is terminated. In this way, a new registered place reflecting the user's preference is added to the registered place data and imported into the navigation device 2.

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, based on the input registration place data, the target facility type as an extraction condition when extracting the facility data is set (step S40), and the DVD-ROM 29 is set by the disk drive 28 according to the extraction condition. The facility data related to any facility is extracted from the facility data in the map data read from (step S60). The facility data thus extracted is added to the registered location data (step S70), and the registered location data to which the facility data is added is written and stored in the flash memory 25 (step S80). Since it did in this way, even if a user does not register when transferring registration place data, the facility suitable for a user's preference can be made into a registration place.

(2) When the target facility type is determined in step S40, the same kind of facility registered in the input registration place data is selected as the same kind of registered facility (step S30), and the same kind registration is performed. The facility data related to the same type of facility as the facility is extracted in step S60. Since it did in this way, the facility data regarding the facility which suits a user preference can be extracted, and the facility data can be added to registration place data.

(3) An extraction area is set based on each position of the same type registered facility selected in step S30 (step S50), and the facility data relating to the same type of facility as the same type registered facility is extracted in step S60. It was decided to extract in Since it did in this way, the facility data of the facility in an appropriate position according to a user's registration situation can be extracted.

(4) In step S50, if the area surrounded by the respective positions of the same type of registered facility is set as the extraction area, the facility data can be extracted for the facility in the area often used by the user.

(5) Further, in step S50, if an extraction area is set around each position of the same type registered facility that is at a predetermined distance or more away from the pre-registered home among the same type registered facility, the user The facility data can be extracted for a facility in a region away from the living area, for example, a frequently visited facility.

(6) In step S50, if an extraction area is set around the road extending along each position of the same type registered facility, the extracted area is positioned along the same road as the already registered same type registered facility. Facility data can be extracted for the facility.

(7) When a list of registered locations in the registered location data is displayed, the list of newly added registered locations at the time of import is displayed in a display form different from other registered locations. Since it did in this way, it can make a user discriminate | determine easily which registration place was newly added.

  In the above-described embodiment, an example has been described in which facility data to be newly added to a registered location is extracted without considering the update history of map data when extracted from map data. However, the facility data may be extracted in consideration of the update history of the map data. For example, the map data may be upgraded in the navigation device 1 before transferring registered location data and the navigation device 2 after transferring registered location data. In such a case, in the current version of map data used in the navigation device 2, that is, map data stored in the DVD-ROM 29, flag information indicating that is added in advance to the newly added facility. Give it. And when extracting the facility data newly added to a registration place, the facility data regarding the facility in which this flag information was increased is extracted. In this way, since there was no map data before the registration location data transfer, it is not registered, and facilities added after the version upgrade can be added as new registration locations.

  In the above-described embodiment, an example in which facility data to be newly added to a registered place is extracted from map data without considering the user's use history with respect to the registered place has been described. May be. For example, in the registration location data, the number of times set by the user as the destination is recorded for each registration location as a usage history. When newly extracting facility data to be added to a registered location, by setting the vicinity of the registered location with a large usage history as an extraction area, a facility that is close to the registered location frequently used by the user is newly registered. Can be added as a ground. Alternatively, the number of facilities in the facility data to be extracted may be changed according to the total number of usage histories of each registered location selected as the same type of registered facility. In this way, the number of registered locations to be added can be increased for facility types frequently used by the user, and the number of registered locations to be added can be decreased for facility types that are not frequently used. As a result, it is possible to add a registration place according to the user's preference.

  In the above-described embodiment, the example in which the registered location data is transferred via the memory card 3 has been described. However, the registered location data may be transferred via another device. 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. In addition, the registered location data can be transferred by various methods such as using a magnetic disk or connecting via wireless communication using radio waves or infrared rays.

  Each embodiment and various modifications described above are merely examples, and the present invention is not limited to these contents as long as the features of the invention are not impaired.

  In each of the embodiments described above, the facility data reading means is realized by the disk drive 28, the storage means is realized by the flash memory 25, and the other means are realized by the processing of the control circuit 21. Specifically, the condition setting means is realized by steps S30 and S40, the area setting means is step S50, the extraction means is step S60, and the addition means is realized by step S70.
