Description

  The present invention relates to a navigation technology having a function of searching for a spot corresponding to a preset category and a function of registering an arbitrary spot by a user operation, particularly when a spot searched by a category is registered. The present invention relates to a navigation apparatus, a method and a program for managing the registered points by categorizing them.

  In general, a navigation device is a device that searches for a route to a destination desired by a user, displays the current location and the searched route on map data as needed, and guides the user to the destination. In particular, in-vehicle navigation devices are widely used, and their functions are being advanced. The destination mentioned here is a point as a destination, and includes not only the final destination but also a transit point.

  Hereinafter, with reference to FIG. 7, the outline | summary of a vehicle-mounted navigation apparatus is demonstrated concretely. As shown in FIG. 7, the navigation device is provided with an absolute position / orientation detection unit 1, a relative orientation detection unit 2, and a vehicle speed detection unit 3 as means for detecting the vehicle position that is the current location of the automobile.

  Among these, the absolute position / azimuth detection unit 1 receives GPS radio waves transmitted from GPS satellites with an antenna, a receiver or the like in order to calculate the absolute position coordinates and azimuth on the ground surface for the own vehicle position. Part. The relative orientation detection unit 2 is a part that detects the relative orientation of the vehicle position using a gyro sensor or the like. The vehicle speed detection unit 3 is a part that processes vehicle speed pulses obtained from the automobile in order to calculate the speed at the vehicle position.

  In the navigation device, a main CPU and its peripheral circuit 4 are installed as a control unit of the entire device. Basic functions realized by the main CPU and its peripheral circuit 4 include a function for displaying map data and the vehicle position, a function for setting an arbitrary point as a destination, and a function for acquiring the vehicle position by GPS information. There are a function for searching a route from the vehicle position to the destination, a route guidance control function for controlling route guidance of the searched route, and the like.

  Further, a ROM 5, DRAM 6, Flash ROM 7, and VRAM 8 are provided as data storage units for exchanging information between the main CPU and its peripheral circuit 4. Among these, the ROM 5 stores a BIOS, a boot program, and the like, and is a part accessed by the main CPU and its peripheral circuit 4 when the apparatus is started up.

  The DRAM 6 is a memory used for a work area and the like, and the VRAM 8 is a memory for performing video display on the display unit 10 described later. Further, the flash ROM 7 is a non-volatile memory, and the memory contents are held by the backup power supply while the main power supply of the apparatus such as an accessory power supply of the automobile is turned off.

  Moreover, the output part 10 and the input part 11 are installed in the navigation apparatus. The output unit 10 and the input unit 11 are connected to the main CPU and its peripheral circuit 4 via the user interface unit 9. The user interface unit 9 connects the output unit 10 and the input unit 11 to the main CPU and its peripheral circuit 4, and uses an I / O control circuit, a driver, and the like.

  The output unit 10 includes a display unit 10a and a speaker 10b. The display unit 10a displays map data, own vehicle position, guidance display, and various operation menus. The speaker 10b outputs a voice at the time of guidance.

  The input unit 11 is a part for inputting an operation command from the user to the main CPU and its peripheral circuit 4, and includes a touch panel unit 11a and a remote controller 11b. The touch panel unit 11a is formed on the display screen of the display unit 10a.

  Further, the navigation device is provided with a disk control unit 12, an FM multiplex reception and processing unit 13, and an external recording device control unit 14. These components are also connected to the main CPU and its peripheral circuit 4. The disk control unit 12 is a means for storing a map database, a search database that collects point information such as stores, buildings, and resorts, and includes a CD-ROM, a DVD-ROM, a hard disk, and the like.

  The FM multiplex reception and processing unit 13 is a part that receives FM broadcast waves and processes various traffic information from the received radio waves. The external recording device control unit 14 is an interface for recording data on an external recording medium (memory stick, memory card, CF card, etc.) and reading data.

  In the navigation apparatus as described above, when setting a destination, a point serving as a destination is searched from a search database stored in the disk control unit 12. With respect to this point search, a user searches for a desired point by inputting operation of basic information such as an address and a telephone number of the point to be searched.

  Also, there are times when the user does not know the address or telephone number of the location, or the user's action purpose is clear (for example, wanting to eat or stay), but the destination location is not narrowed down. In such a case, a so-called category search that searches for a point corresponding to the category by narrowing down the category to which the point belongs is effective.

  Hereinafter, the category search will be specifically described. In the navigation apparatus shown in FIG. 7, a search database stored in the disk control unit 12 is used. The user performs an input operation from the touch panel unit 11a, displays the category classification on the display unit 10b, and traces the category to find a desired point.

  The search database stored in the disk control unit 12 is configured as shown in FIG. As is clear from FIG. 8, in the search database, restaurants, leisure facilities, accommodation facilities, etc. are set as category classifications, and restaurants A, B,... , B,... Y, hotels A, B,.

  Next, examples of operation screens are shown in FIGS. FIG. 9 shows operation screen transitions for searching for restaurants, and FIG. 10 shows operation screen transitions for searching for resorts. First, a destination search menu screen is called on the display screen of the display unit 10a by a user input operation. The category is selected by the user touching the display area “Restaurant” in FIG. 9 and the display area “Leisure facility” in FIG. 10 (shown in the upper part of each figure).

  When a category is selected as described above, the display screen of the display unit 10a is switched from the touch panel unit 11 destination search menu screen to the corresponding facility list screen, and a list of points belonging to each category is displayed (FIG. 9 and FIG. 9). (Shown in the middle of FIG. 10). Since the display screen of the display unit 10a is the touch panel unit 11a, the user touches the display area “Restaurant X” or “Recreation Area Y” to select the point.

  As a result of selecting a desired point, the corresponding facility list screen is switched to a point display menu screen, and a point operation menu such as “set as destination” or “set as waypoint” is displayed together with the map data of the point ( (Shown in the lower part of FIGS. 9 and 10). On this display screen, the selected point is displayed on the map with a + mark, and at the same time, menu settings such as “Set as destination”, “Set as waypoint”, and “Register point” are displayed at the upper right of the screen.

  Here, if the user touches the display area “set as destination”, “restaurant X” or “excursion place Y” is set as the destination. According to such a category search, even if the user does not know the address or telephone number of the point where he / she wants to go, if the user knows only the category to which the point belongs, the user can find the desired point from the category and Can be set as the destination or waypoint.

  Furthermore, many navigation devices have a location registration function for registering locations used in the past in addition to the location search function. The point registration is a function for registering a point as a registered point by a user operation and creating a registered point list when the user determines to use the point again for a point set as a destination by the user.

  As shown in the lower part of FIG. 9 and FIG. 10, the point display menu screen includes a display “spot registration” in addition to the menu display “set to destination” and “set to waypoint”. If the user touches the display area of “spot registration”, the spot registration function works (see FIG. 11). At this time, in the navigation device of FIG. 7, the location information of the spot is registered in the flash ROM 7 which is a nonvolatile memory or the external recording device control unit 14.

  According to the navigation device having such a location registration function, by registering in advance a frequently used location as a destination or waypoint, a desired location can be selected from the created registered location list. And can be quickly selected as a stopover. Therefore, the point search can be omitted when setting the destination and the waypoint, and the workability is improved.

  By the way, the registration points listed in the registration place list are usually arranged in the order registered by the user. For this reason, it is convenient when calling a registered point that has been registered very recently, but it is inconvenient to call a registered point that has been registered for a long time.

  In addition, after a user registers a point, the user rarely bothers to delete the registered point from the registered place list even if the frequency of use of the registered point decreases. Therefore, if the location registration function is used for a long time, the number of registration locations will only increase.

  Moreover, in the registered place list, it is common to display only the name of the registered point, or add the address or coordinates to the name. Therefore, the number of registration points increases, and the registration place list becomes longer. As a result, it becomes difficult to discriminate each registration point, and the user tends to take time to find a desired registration point.

  Therefore, there is a need for a technique that makes it easy for a user to find a desired registration point even when the number of registration points increases. For example, a conventional technique described in Patent Document 1 has been proposed. The technique described in Patent Document 1 is characterized in that at the time of point registration, a user selects a category of a target to be registered (in Patent Document 1, personal, business, leisure, etc.), and registers after adding the category of the point. There is.

  According to such a conventional technique, even if the number of registered points increases, the category of the points can be displayed together with the registered points. Therefore, the user can easily find a desired registration point from the registration place list using the category as a guide.

JP 2003-207356 A

  However, the technique disclosed in Patent Document 1 has the following problems. That is, in the technique of Patent Literature 1, when a user performs point registration, the user himself / herself has to decide on a category corresponding to the registered point. A category is selected from a plurality of candidates, but the selection of this category may take time.

  In Patent Document 1, there are four major classifications and ten major classifications indicated by landmarks in each major classification. When there are a wide variety of categories in this way, the user may be confused as to which category the point to be registered corresponds to. Therefore, the category selection work at the time of location registration has a heavy work burden on the user.

  Moreover, the point where it was difficult to determine the category often has a weak connection between the category and the point even when the category is displayed after the point registration. Therefore, even if the category is used as a guide, the registration point cannot be found quickly.

  The present invention has been proposed in order to satisfy the above-mentioned demand, and its purpose is to automatically assign an appropriate category with respect to the point to be registered, thereby reducing the user work at the time of point registration, It is another object of the present invention to provide a navigation device, method and program that are capable of reliably managing a large number of registration points and are excellent in workability and operability.

  In order to achieve the above-mentioned object, the invention according to claim 1 is that the user inputs a basic information including a location address or a telephone number or a category to which the location belongs, so that a desired location is selected from the locations on the map data.

A category storage means for storing the location information when the location search means registers the location searched by the location search means. Only to those, wherein the configured to record together the categories stored temporarily in the category storage means.

  The invention of claim 5 captures the invention of claim 1 from the viewpoint of the method, and the basic information including the address or telephone number of the point or the category to which the point belongs is input on the map data by the user. A point search step for searching for a desired point from among points, a point registration step for registering an arbitrary point as a registered point, a destination setting step for setting an arbitrary point as a destination, and a current location detection for detecting the current location In the navigation method of performing a step, a route search step for searching for a route from the current location to a destination, and a route guidance control step for controlling guidance guidance of the route, the point search step searches for the point A category storing step of temporarily storing the category when the site registration step is performed. When registering the searched point in step, it is characterized in that recording together said categories temporarily stored in the category storage step in association with the positional information of the point.

  The invention of claim 6 captures the inventions of claims 1 and 5 from the viewpoint of a program, and a user inputs basic information including a location address or telephone number or a category to which the location belongs by using a computer. A point search function to search for a desired point from points on map data, a point registration function to register any point as a registered point, and a destination setting function to set any point as a destination In the navigation program for causing a computer to realize a current location detection function for detecting the current location, a route search function for searching for a route from the current location to the destination, and a route guidance control function for controlling guidance of the route. When searching for a location by tracing the category with the function, a category saving function for temporarily saving the category is added to the computer. In the point registration function, when registering a spot searched by the spot search function, the computer temporarily records the category temporarily saved by the category saving function in association with the position information of the spot. It is characterized by realizing.

  In the present invention as described above, the category selected by the user at the time of point search is temporarily stored in the category storage means. Then, when trying to register the point searched by tracing the category by the point registration means, the location information of the point and the category are recorded in association with each other.

  In other words, the category used at the time of searching is automatically assigned to the category searched point. For this reason, even if the number of point registrations increases, it is possible to easily find a registration point desired by the user from among a large number of registration points using the category as a landmark.

  Moreover, since the category assigned to the registered point is the category when the point is searched, the connection between the assigned category and the registered point is strong for the user. Therefore, it is possible to quickly find the registration point using the category as a guide.

  According to a second aspect of the present invention, in the navigation apparatus according to the first aspect, the point registration unit is configured to display and control the already registered points for each category recorded in association with the position information of the points. It is characterized by that.

  In the invention of claim 2 as described above, since the point registration means controls display of the registered points by category, the user can easily grasp the registered points and can easily find the desired registered points. Moreover, since the registration point is derived from the category search by the user, the user can find the registration point more quickly without hesitation when selecting the category of the registration point.

  In the invention of claim 3 having the above-described configuration, when a point searched from a search condition different from the category is to be registered, the point is recorded in a state where there is no category. In particular, in the invention of claim 4, when a point search is performed using basic information including the address or telephone number of the point, the basic information is added to the searched point and recorded. In this way, by changing the information given to the registration point according to the point search method, the discrimination power of the registration point is increased, and it becomes easy to find the desired registration point.

  According to the navigation apparatus, method, and program of the present invention, by assigning the category used at the time of search and performing point registration, the user work at the time of point registration can be reduced, and at the same time, the management of the registered point is facilitated. Become.

  Hereinafter, an example of an embodiment for carrying out the present invention will be specifically described with reference to FIGS. The outline of the present embodiment is the same as the conventional example shown in FIG.

(1) Configuration of the present embodiment The present embodiment is applied to an in-vehicle navigation device that performs category search and location registration. As shown in FIG. A vehicle position acquisition unit 20, a departure point setting unit 21, a point search unit 22, a destination setting unit 23, a route search unit 24, and a guidance control unit 25 are provided.

  The own vehicle position acquisition unit 20 is a part that acquires the own vehicle position based on GPS information, information from a gyro sensor, or the like. The departure place setting unit 21 is a part that sets the vehicle position as a departure place. The point search unit 22 is a part that searches for a point on the map data based on basic information such as the address and telephone number of the point, or a category to which the point belongs.

  The destination setting unit 23 is a part that sets an arbitrary point as a destination by a user input operation including the point searched by the point searching unit 22. The route search unit 24 is a part that searches for a route from the departure point set by the departure point setting unit 21 to the destination set by the destination setting unit 23. The guidance control unit 25 is a part that performs guidance control of the route searched by the route search unit 24 by guidance display on the display screen of the display unit 10a and guidance voice from the speaker 10b.

  The feature of this embodiment is that the category used at the time of the point search is temporarily saved, and the category temporarily saved is registered in association with the position information of the registered point at the time of registration of the search point. As a hardware configuration for realizing these, a category storage control unit 26 and a point registration unit 27 are provided in the main CPU and its peripheral circuit 4.

  When the spot search unit 22 searches for a spot by category search, the category storage control unit 26 temporarily stores the category in the DRAM 6 for the category used in the spot search unit 22. The category to be stored is the name data as data, and specifically includes restaurants, leisure facilities, accommodation facilities, and the like.

  The point registration unit 27 records and registers the position information of an arbitrary point in the flash ROM 7 which is a nonvolatile memory or the external recording device control unit 14 by a user input operation including the point searched by the point search unit 22. This is the part that creates a land list. In addition, when the spot search unit 22 searches for a spot based on the category, the spot registration unit 27 stores the category of the spot together with the position information of the spot in the registered place list on the FlashROM 7 or the external recording device control unit 14. It is supposed to be.

(2) Spot registration processing according to this embodiment Next, spot registration processing according to this embodiment will be described with reference to the flowchart of FIG. First, a destination search menu screen is displayed on the display screen of the display unit 10a by the user's input operation (see the upper part of FIG. 9 and FIG. 10). A menu is displayed (S101).

  Since the display screen of the display unit 10a is the touch panel unit 11a, the category of the touched display area is selected by the user touching the area where the desired category is displayed (Yes in S102). ). The selected category, more specifically category name data, is temporarily stored in the DRAM 6 (S103).

  Further, when the user selects a category, the display screen of the display unit 10a is switched to a list display of spot information belonging to the selected category, and a plurality of spot information is displayed as a list on the display screen (S104). Subsequently, when the user touches the area where the desired spot information is displayed, the spot information of the touched display area is selected (Yes in S105).

  Thus, when the user selects a desired point, the display screen of the display unit 10a becomes a display of a map of the selected point and a point operation menu (S106). On this screen, when the user touches the area where the spot registration is displayed, the spot registration process is selected (Yes in S107). As a result, after associating the category name temporarily stored in the DRAM 6 with the position information of the selected point, the information is stored in the flash ROM 7 which is a nonvolatile memory or the registered place list on the external recording device control unit 14. Record (S108).

  FIG. 3 shows a display example of the registered place list. In the registered place list of FIG. 3, the category to which each point belongs is displayed as a list together with the name and coordinates of the point as the point information. In such a registered place list, since the point information and the category are associated with each other, it is possible to display only the points belonging to a single category (detailed in the registered place list display process in the subsequent stage). ).

(3) Registered Land List Display Processing According to the Present Embodiment Next, processing for displaying the registered land list in the present embodiment will be described with reference to the flowchart of FIG. 4 and the screen transition examples of FIGS. First, a destination search menu screen is displayed on the display screen of the display unit 10a by a user operation (shown in the upper part of FIG. 5), and a search menu display of a plurality of categories and a registered destination list is displayed on the screen (S201). .

  As described above, since the display screen of the display unit 10a is the touch panel unit 11a, the display of the registered place list is selected by the user touching the displayed area “registered place list”. (Yes in S202). As a result, the category information is read from the registered place list (S203), and the display screen of the display unit 10a becomes the display screen of the category list displaying a plurality of categories as shown in the lower part of FIG. 5 (S204).

  Subsequently, when the category of the registered place is selected from the category list shown in the lower part of FIG. 5 by the user's touch operation (Yes in S205, a restaurant is selected in the lower part of FIG. 5), the display unit 10a. The display screen is switched to the display of the registered location list of the registered location information belonging to the selected category, and the location information of the registered location is displayed on the display screen (S206, shown in the upper part of FIG. 6).

  Subsequently, when the user touches the area where the desired spot information is displayed from the registered place list, the spot information of the touched display area is selected (Yes in S207, restaurant in the upper part of FIG. 6). B is selected). Thus, when the user selects a desired point, the display screen of the display unit 10 displays a map of the selected point and a point operation menu (S208, illustrated in the lower part of FIG. 6).

  In the display screen shown in the lower part of FIG. 6, a map display of the restaurant B that is the selected registration location and point operation menus “set as destination” and “set as waypoint” are displayed. Here, if the user touches the display area “set as destination”, “restaurant B” is set as the destination. Since restaurant B has already been registered as a registered location, the operation menu display “Register location” has been deleted.

(4) Operational effects of the present embodiment The operational effects of the present embodiment described above are as follows. In the present embodiment, when the category selected by the user at the time of category search is temporarily stored in the DRAM 6 and the location searched for the category is to be registered, the category name is associated with the location information of the registered location. It is recorded.

  That is, it is possible to register after automatically assigning the category used at the time of searching for the category searched. For this reason, it is not necessary for the user himself / herself to select the category of the point at the time of point registration, and the user's workload can be reduced.

  Further, even if the number of registered points increases, it is easy to find a registered point desired by the user from among a large number of registered points with a category as a landmark. In addition, the category given to the registered point is a category that the user has selected when searching for the point. For this reason, for the user, the assigned category and the registration point are strongly connected psychologically, and the registration point can be quickly found using the category as a guide.

(5) Other Embodiments The present invention is not limited to the above embodiments. Although the above embodiment is realized by controlling a computer including a peripheral device with a program, the implementation modes of the hardware and the program in this case can be variously changed.

  In addition to the navigation apparatus and method thereof, the present invention can also be grasped as a program or a computer-readable recording medium recording the program. The program realizes the effects of the present invention by utilizing a physical processing device such as a CPU and various chip sets incorporated in the navigation device. Furthermore, although the said embodiment was applied to the apparatus for vehicle mounting, it is not restricted to this, It is also possible to employ | adopt for a portable navigation apparatus.

  By the way, when searching for a location, the search may be performed based on search conditions different from the category, for example, basic information on locations such as addresses and telephone numbers. In this case, since the category is not used at the time of the point search, when registering the searched point, the category may be recorded as a blank in the registration place list. Or you may make it give the basic information used as search conditions with respect to the searched point, and to record on a registration place list.

  As described above, since many of the conventional registered location lists are displayed with only the name of the registered location or an address or coordinates added to the name, if the search condition is a telephone number, each registered location list in the registered location list The amount of information will surely increase.

  According to the embodiment having such a registered place list, only the points registered after the category search are categorized, and the category column is blank or the basis when a search method other than the category search is used. Since the information is described, the identification of the registration point is improved. That is, even if there are many registration points, a desired registration place can be found quickly.

  Further, as another embodiment, the category information at the time of search is held until the power is turned off, and the point is registered near the destination set by the category search (since the destination flash is generally not the getting-off position). When an operation is performed, it may be registered together with a category at the time of search.

  Furthermore, as another embodiment, the category information at the time of search is held until the destination is reached, the power is turned off, and then the power is turned on again (in this case, not the DRAM 6). , Temporarily stored in the FlashROM 7 or the external storage control unit 14), and when the point is registered before the vehicle starts moving, it may be registered as category information at the time of search. If the vehicle starts running before the location is registered, the category at the time of retrieval temporarily stored in the FlashROM 7 or the external storage control unit 14 may be deleted or overwritten with the category information set next time. Also good.
