Description

  The present invention relates to a navigation device and a search method in the navigation device, and can be applied to, for example, a car navigation device. The present invention accepts complex search conditions in advance, displays a corresponding menu in response to a search instruction, and accepts a selection by the user, thereby easily and quickly finding a facility or store suitable for the user's wishes. To be able to.

  2. Description of the Related Art Conventionally, a car navigation apparatus holds a database of facility and store data, and uses this database for the convenience of users.

  In other words, when a search for a genre such as a facility or a store is instructed by the user, the car navigation device searches the database using the instructed genre. In addition, the search results are displayed in a list according to the order of time, region, etc., and the selection by the user is accepted. Further, the search is further narrowed down based on the current position and notified to the user.

  Thereby, the car navigation device searches the database by the genre of the resort, for example, further searches the database by the genre of the aquarium that further classifies the genre of the resort, for example, and displays a list of the corresponding resorts. The destination setting is received by the selection of the list display by the user, and navigation processing is executed. Further, for example, the data of facilities and stores are searched according to the genre of the gas station, and the gas station around the current position is notified to the user on the map.

  Further, when the user inputs the name of the facility or the store and instructs the search, the database is searched by this name, and the search result is displayed on the map. Further, according to the setting of the destination by the user, the facility and the store related to this name are set as the destination and the navigation process is executed.

  Regarding such a database search, Japanese Patent Application Laid-Open No. 2002-340596 proposes a method for searching for a plurality of genres to improve the convenience of the user.

  By the way, you may want to go to the bathroom while driving. In this case, the facilities and stores available to the user include facilities and stores in a plurality of genres such as a gas station, a road station, and a convenience store.

  In a conventional car navigation device, in such a case, select any genre from these genres to search for facilities and stores near the current position, and if no facilities or stores available in the searched genre are found, The genre is changed again and the search is repeated. Accordingly, in this case, there is a problem that it is difficult to find a desired facility and store easily and quickly. Even if a nearby facility or store can be found in a specific genre, there may be a facility or store in a different genre that is closer to the facility or store. The corresponding facility or store has not been found.

  For example, when eating, the nearest store is searched according to the genre of the restaurant. However, users may hate Japanese food, for example, and may hate stores of specific chain stores. Thus, in this case, in the conventional car navigation device, a store that does not match the user's preference is searched, and in this case as well, there is a problem that it is not possible to find a facility or store that appropriately corresponds to the user's desire. In this case, for example, if a restaurant other than Japanese food is searched, a store that matches the taste can be found. However, when searching for a restaurant other than Japanese food, a search is made by a number of genres such as Western food and family restaurants. As a result, it becomes difficult to find a desired store easily and quickly.

As proposed in Japanese Patent Laid-Open No. 2002-340596 as one method for solving these problems, a method of searching for these facilities and stores by a plurality of genres is conceivable. Therefore, there is a problem that the input of a genre for search is complicated.

On the other hand, the location data of stores and facilities is data that can be set as a destination in the car navigation device 1 and can execute navigation processing, and can display the locations of facilities and stores on a map. It is.

  On the other hand, in the special notes, the chain store name is recorded when the store or facility is a chain store. Further, for example, data such as business hours and the presence / absence of a parking lot are allocated.

  The main arithmetic unit 6 is constituted by a central processing unit, and according to the recording of the read-only memory (ROM) 15, a work area is secured in the random access memory (RAM) 16 to start up the operation, and the operation is recorded in the read-only memory 15. By executing the program, the overall operation of the car navigation apparatus 1 is controlled. In this way, in this car navigation apparatus 1, although the program of the main arithmetic unit 6 is provided by prior installation, it is provided by downloading via a network such as the Internet instead of provision by such prior installation. Further, it may be provided via various recording media such as an optical disk, a magnetic disk, and a memory card.

  The main arithmetic unit 6 displays the main menu screen on the display device 10 by the processing of this program, and accepts the selection of the menu by the operation of the remote commander 11 and the operation of the touch panel. When a menu for instructing reproduction of video content is selected on the main menu screen, the video data and audio data of the video content are reproduced by the optical disc drive 4 and output from the display device 10 and the speaker 7. When a menu for instructing reproduction of music content is selected, the music content is reproduced by the optical disc drive 4 and output from the speaker 7 in the same manner.

  On the other hand, when a menu for instructing navigation processing is selected, the main computing unit 6 acquires position data of the current position from the current position detector 2. Further, the map data recorded in the hard disk device 14 is searched based on the position data, and a map of the current position is displayed on the display device 10 as shown in FIG. The main computing unit 6 displays a menu bar B1 in a strip shape below the map display, and displays a menu (current position) for instructing display of the current position on the menu bar B1. When the conditions for complex search are registered, a menu (composite search) for instructing complex search is displayed on the menu bar B1.

  When the main computing unit 6 displays the map of the current position in this way, the display of the map is zoomed up and down by the operation of the remote commander 11 and further scrolled. In addition, a series of processing related to navigation is executed.

  In the series of processes, when the setting operator is operated in the remote commander 11 or on the operation panel of the car navigation device 1, the main arithmetic unit 6 changes the display on the display device 10 according to the navigation function. Switch to the menu screen display for each setting. Further, when an additional menu for complex search is selected on this menu screen, a complex search setting screen shown in FIG. 4 is displayed. Here, the car navigation device 1 records and holds the compound search condition input by the user in the nonvolatile memory 13, and when the user selects the compound search menu described above with reference to FIG. A menu for instructing a search is displayed according to the search conditions recorded in FIG. Also, by selecting this menu, the database recorded in the hard disk device 14 is searched according to the corresponding complex search condition recorded in the nonvolatile memory 13 and the search result is notified to the user.

  The complex search setting screen is a screen for inputting the complex retrieval condition. The main computing unit 6 displays a title (composite search) indicating that it is a complex search setting screen at the top of the complex search setting screen, and then displays a title input box B2. Here, the title input box B2 is an area for inputting a title to be set in a menu for instructing search according to the search condition input on the complex search setting screen. In the example of FIG. 4, the title “Search 1”, which is the default display, is set. When the input box B2 is selected by the operation of the remote commander 11 or the operation of the touch panel, the main arithmetic unit 6 switches the display in the input box B2 and displays a pop-up menu for inputting a title. . Here, this pop-up menu is formed, for example, by displaying a list of characters of Aiweo, and the main arithmetic unit 6 accepts input of a character string by accepting input of a character string by this pop-up menu by operating the remote commander 11 and the touch panel. In this way, in the title input box B2, for example, when inputting conditions for searching for facilities and stores for toilets on this composite search setting screen, a title such as “toilet” is input, When a condition for searching for a store to eat together is input on the composite search setting screen, a title such as “kid meal” is input.

  The main computing unit 6 displays an area AR1 for displaying the subsequently input genre, and displays a genre input box B3A for search in this area AR1. When the input box B3A of this genre is selected by the operation of the remote commander 11 or the operation of the touch panel, the main arithmetic unit 6 switches the display in the input box B3A and is classified into a large classification related to the database setting. A list of such genres is displayed by a pop-up menu. In addition, by the operation of the remote commander 11, the selection of the genre displayed by this pop-up menu is accepted by the operation of the touch panel. At this time, when the user instructs display of lower-level genres, a pop-up menu displays a list of genres related to the minor categories included in the major categories selected by the user, and the user selects a genre. It accepts by the genre of this short sentence.

  The main computing unit 6 displays a genre addition menu (genre addition) below the area AR1 for displaying this genre, and when the user selects this genre addition menu, a genre input box is additionally displayed. To do. Accordingly, in the example shown in FIG. 4, the genre addition menu is selected twice by the user, and the genre input boxes B3A to B3C are displayed. The main computing unit 6 accepts input of a genre by the user for the additionally displayed input boxes B3B and B3C in the same manner as the input box B3A displayed first.

  As a result, the main arithmetic unit 6 accepts an input of a genre to be searched by each genre based on the large classification and each genre based on the small sentences.

  The main arithmetic unit 6 displays a box B4 for setting the display order of the search results below the area AR1 for displaying this genre. By selecting this box B4, "display in genre order" and "display in close order" are displayed. "Menu is displayed. Here, the “display in order of genre” menu is a menu for selecting display of search results in the order of genres set on this complex search setting screen, and the “display in order of close” menu is close to the current position or the like. This is a menu for selecting display of search results in order. The main computing unit 6 displays these “display in genre order” and “display in close order” menus, and displays the title of the menu selected by the user in the box B4.

  The main arithmetic unit 6 displays a detailed setting menu (details) at the right end of the input boxes B3A to B3C for each genre. When the detailed setting menu is selected by the user, the composite search setting screen is displayed. The display is switched to the detailed setting screen display shown in FIG.

  Here, the main arithmetic unit 6 displays a title (combined search genre detailed setting) indicating that it is a detailed setting screen for a genre at the top of the detailed setting screen, and then displays the genre to be set in detail. . Accordingly, the example of FIG. 5 shows a case where the detailed setting menu is selected in the second input box B3A in which the family restaurant genre is input in the example shown in FIG.

  The main computing unit 6 then displays an area AR2 for inputting items to be excluded from the search target, and displays an input box B5A for items to be excluded from the search target in this area AR2. When the input box B5A is selected by the user, the main arithmetic unit 6 displays a list of genres in the lower hierarchy of the genre related to the detailed setting by a pop-up menu. In addition, by the operation of the remote commander 11, the selection of the genre displayed by this pop-up menu is accepted by the operation of the touch panel. In this processing, when the genre related to the detailed setting is a genre of a small classification, the main arithmetic unit 6 displays a list of items set in the special notes of the facility and store data by a pop-up menu, and is selected by the user. Accept.

  The main arithmetic unit 6 further displays a menu for adding a genre (genre addition) below the area AR2 for displaying the items not to be searched, and when the user selects the menu for adding a genre, the search target is displayed. Displays an additional input box for items to be excluded.

  As a result, the main arithmetic unit 6 accepts input of the genres to be searched for, for example, the lower-level genres excluded from the search targets and the chain stores related to the special notes. The main arithmetic unit 6 records the items input by the user on the composite search setting screen in this manner in the nonvolatile memory 13.

  When the return operator is operated on the remote commander 11 or the operation panel, the main arithmetic unit 6 switches the screen display of the detailed setting to the screen display of the original composite search setting. When the return operator is operated in the same manner while the composite search setting screen is displayed, the display of the display device 10 is switched to the display related to the original navigation processing.

  As described above with reference to FIG. 3, when the various complex search conditions are input together with the title, the main arithmetic unit 6 displays a compound search menu on the menu bar B1. When this compound search menu is selected by the user, as shown by the arrow A in FIG. 6 in comparison with FIG. 3, a menu (going to the toilet) displaying the title input on the complex search setting screen (see FIG. 6). Display). When any of the menus displaying the title is selected by the user, the database of the hard disk device 14 is searched according to the search condition corresponding to the selected menu, and the search result is notified to the user.

  FIG. 1 and FIG. 7 are flowcharts showing a series of processing procedures of the main computing unit 6 relating to the selection of the menu for this complex search. When the compound search menu described above with reference to FIG. 3 is selected by the user, the main arithmetic unit 6 moves from step SP1 to step SP2, and detects the selection by the user of the function of compound search. Subsequently, in step SP3, the main arithmetic unit 6 displays a menu of each title relating to the search condition registered by the processing described above with reference to FIGS. 3 to 5 as shown in FIG. Further, in the subsequent step SP4, the selection of the composite search item is detected by the selection of this menu by the user, and in the subsequent step SP5, the corresponding search condition recorded in the nonvolatile memory 13 is acquired, and this search condition is set as the search condition. The database is searched for one set genre. Here, the main computing unit 6 executes a search process in a certain range of areas based on the approximate center position of the map displayed on the display device 10, and thereby the current position detection unit 2 performs, for example, a navigation process. When the map is displayed centering on the detected current position, the database is searched in a certain range of area centered on the current position. In addition, when the user scrolls the map display to display the destination map, the database is searched within a certain range centered on the destination, and the route to the destination is further displayed. If it is, the database is searched in an area within a certain range centering on the position of the halfway route being displayed. Note that a certain range for this search is accepted in advance by operating the setting menu.

  Subsequently, in step SP6, the main computing unit 6 determines whether or not the facility or the store has been hit by the search in step SP5, and if a negative result is obtained here, the process proceeds from step SP6 to step SP7 (FIG. 7). It is determined whether all genres set in the search condition have been searched. If a negative result is obtained here, the main computing unit 6 moves from step SP7 to step SP8, switches the search target to the next genre set as the search condition, and similarly searches the database, and returns to step SP6. .

  On the other hand, if a positive result is obtained in step SP6, the main computing unit 6 moves from step SP6 to step SP9, and the hit facility or store is excluded from the search targets set in the genre provided for this search. Determine whether the item is applicable. Here, if the item corresponds to an item to be excluded from the search target, the main computing unit 6 moves from step SP9 to step SP10, excludes the corresponding facility and store from the search result, and then moves to step SP7. On the other hand, if it does not correspond to an item to be excluded from the search target, the process moves from step SP9 to step SP11, stores the hit facility / store data in the buffer memory storing the search result, and then moves to step SP7. .

  Thereby, the main computing unit 6 is recorded in the database by the OR search of the genre input on the composite search setting screen, and further by the search excluding the specific facility and store classified into the genre related to the OR search. When the facility and store data are searched and all genres related to the complex search conditions are searched, an affirmative result is obtained in step SP7, and the process moves from step SP7 to step SP12.

  Here, the main arithmetic unit 6 determines the display order registered on the search condition setting screen from the record in the non-volatile memory 13, and if the display order is set to be close to the display order, the step is displayed. The process proceeds from SP12 to step SP13. Here, when the user has selected display of a map based on the current position, the main computing unit 6 sorts the search results in the order from the closest to the current position. In addition, when a map based on a destination, an intermediate route, or the like is displayed, the search results are sorted in ascending order based on the destination or the central point of the map display related to the intermediate route.

  After completing the sorting of the search results in this way, the main arithmetic unit 6 moves from step SP13 to step SP14, displays the sorted search results on the display device 10, and then moves to step SP15 to end this processing procedure. .

  On the other hand, when the user has selected display according to genre order, the main arithmetic unit 6 proceeds from step SP12 to step SP16. Here, the main arithmetic unit 6 sorts the search results in the order of the genre set on the setting screen, and then moves to step SP14, displays the sorted search results, moves to step SP15, and ends this processing procedure.

  Here, FIG. 8 is a plan view showing a search result display screen by the processing of step SP14 of the main computing unit 6 when the user selects the display order in the closest order. In this case, the main arithmetic unit 6 displays the title (combined search result) on the top and displays the map on the right half of the screen. In addition, the title (going to the toilet) set as a search condition is displayed at the top of the left half of the screen, and then the sorted search results are sequentially displayed. In this process, the main computing unit 6 also displays the distance from the reference position used for the sorting in step SP13. In the initial state, the main arithmetic unit 6 sets and displays the focus on the search result displayed at the top of the display of the search results, and switches the focus by a user operation. In addition, the location of the facility and store related to the search result in which the focus is set is displayed on the map. In the example of FIG. 8, the display of this position is represented by an asterisk. Further, the main computing unit 6 displays a menu for switching the display of the search result to the display in the genre order at the bottom of the left side of the screen.

  On the other hand, FIG. 9 is a plan view showing a display screen of a search result obtained by the processing of step SP16 of the main computing unit 6 when the user selects the display order according to the genre order. Also in this case, the main arithmetic unit 6 displays the title (combined search result) at the top and displays the map on the right half of the screen. In addition, the title set as the search condition (to eat) is displayed at the top of the left half of the screen, and then the sorted search results are sequentially displayed. Further, the focus is switched by the user's operation, and the location of the facility and the store related to the search result in which the focus is set is displayed on the map. In addition, a menu for switching the display of search results to a display in the closest order is displayed at the bottom.

  When the user selects a menu for switching the display order displayed at the bottom, the main arithmetic unit 6 sorts the search results and switches the display as shown in FIG. 10 in comparison with FIG.

  With the search result displayed in this way, when the user sets a focus on one of the search results and sets it to the destination or stopover location, the main computing unit 6 sets the facility related to the focused search result. Then, the store is set as a destination or a stop-in place, and navigation processing is executed. The main computing unit 6 opens a menu screen separately to execute processing for search by designation of genre and name, and in this case, the search result is displayed in the same manner.

(2) Operation of Example In the above configuration, in this car navigation device 1 (FIG. 2), a map of the current position, destination, etc. is displayed by the user's operation (FIG. 3), and the destination is set. The navigation process is executed upon receipt.
