Japanese Patent Laid-Open No. 11-160088

  As described above, an icon is displayed on the map, a desired facility is selected from the map by indicating the icon of the facility, and the guidance route to the destination is calculated by setting this as the destination. When setting, for example, when a large number of POI icons are displayed as shown in FIG. 7 (a) and a ramen shop (RM) is designated for the time being, the ramen shop (RM) is set as the destination. The guide route from the current location is displayed along the road.

  At that time, if all currently displayed icons remain displayed, for example, as shown in FIG. 7B, the POI icon ura displayed on the surface layer of the map is hidden in wq. Thus, when a large number of POI icons are displayed as shown in the figure, the guiding path can hardly be made a photon.

  Therefore, when it is known that the facility to be visited is a place to eat, the POI icon displayed on the map is limited to the facility to eat, and the POI icon on the map is to be reduced as much as possible. Even in this case, for example, as shown in FIG. 8 (a), when there are facilities for many meals in the vicinity, there is not much difference compared with the case where icons of all the facilities in FIG. 7 (a) are displayed. Even if the guide route is displayed in this manner, there is no big difference from the display state of FIG. 7B, and the screen must be hard to see the guide route.

  In addition, in order to make the guidance route easy to see, it is possible to select not to display the icon on the map. In this case, for example, as shown in FIG. (RM) icon is also erased, and all surrounding icons are erased, so it is not possible to grasp the surrounding facilities, including the indication of the part to turn left and right, to see the map and drive It must be a hard-to-see map display.

  Therefore, the present invention displays an icon to set a destination, sets a guidance route toward the destination, displays it on the map screen, and guides the guidance route. The main purpose is to provide a navigation device that can prevent the guidance route from being difficult to see due to the display of the POI icon, and that can display the necessary POI icon and display an easy-to-understand map screen. .

  In order to solve the above-described problem, the destination corresponding icon display navigation device according to the present invention displays an icon of a facility on a map including the destination, and displays the icon of the facility by the icon display means. A destination setting means for setting a destination by instructing a facility of an arbitrary icon in the destination, and a destination facility genre detection means for detecting the genre of the destination facility set by the destination setting means The icon display means does not display the icon of the genre detected by the destination facility genre detection means at least within a predetermined distance from the destination.

In the same Example, it is a figure which shows the POI icon display example at the time of departing after having stopped for more than predetermined time after arriving at the destination. In the same Example, it is a figure which shows the POI icon display example at the time of leaving without stopping for more than predetermined time after arriving at the destination. It is a figure which shows a prior art example. It is a figure which shows another prior art example.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a functional block diagram of an embodiment of a destination corresponding icon display navigation apparatus according to the present invention, and shows a functional block diagram in which the present invention can be implemented in various modes. In addition, in the same figure, the function part which performs each function can be said to be a means which performs each function.

  In the functional block diagram of the navigation device shown in FIG. 1, various conventionally used functional units are provided. In the system control unit 10, a CPU, a ROM storing software, and a RAM required for processing of the CPU Etc., and each function unit performs a predetermined operation in association with software recorded in the ROM.

  In the illustrated navigation apparatus, a vehicle position detection unit 13 is connected to the system control unit 10 and the position data of the GPS receiver 11 is input. By inputting the movement data of the vehicle from the azimuth detecting unit 12, the current position of the vehicle is accurately detected.

 The VICS information input unit 14 receives traffic information, in particular, receives traffic information and makes it available for various types of guidance. The instruction signal input unit 17 inputs a signal from the remote controller 15, a signal from the touch panel 16 attached to the monitor, and the like, and further inputs various instruction signals such as recognizing the user's voice. The signal of the instruction signal input unit 17 is captured and used by the user instruction signal capturing unit 43 for each process in the navigation processing unit 31 described later.

  Further, the data input / output unit 19 takes in necessary map data, facility data, etc. from a map / information data recording medium 18 such as a DVD-ROM or a hard disk or a memory card, and the data recording medium is like a hard disk. If data can be written easily, data can be input to the data recording medium so that data imported from outside or data processed by other functional units can be read and used later. ing.

  The image output unit 21 outputs various images to the monitor 20 and displays a map centered on the current location, an enlarged intersection map output from a guidance route guide unit 33 described later, and the like. The voice output unit 23 outputs voice guidance such as a left / right turn guidance of an intersection output from a guidance route guide unit 33 described later from the speaker 22 and further outputs voices such as various warnings as necessary. In the example shown in FIG. 1, the navigation processing part 31 for performing the function of the POI icon display on the map screen especially corresponding to the destination in the present invention is provided. However, in addition to the processing for the present invention, various processing similar to the conventional processing is also performed for map display and guidance route calculation and guidance.

  The example of the navigation processing unit 31 shown in FIG. 1 includes a map display processing unit 32, in which the map display unit 33 displays a map around the current location, and the icon display unit 34 displays various facilities on the map displayed on the monitor. The POI icon is displayed in an overlapping manner. The map display processing unit 32 also performs various map display processes such as a guidance route set by a guidance route setting unit 38, which will be described later, polygon data, and text data.

  The icon display unit 34 shown in the figure includes a destination input icon display unit 35. When setting a destination by a destination setting unit 39 of a guidance route setting unit 38 to be described later, various facility icons on the map screen are displayed. When the destination is set by displaying and indicating an arbitrary facility, the POI icons of all facilities on the map are displayed on the destination input icon display unit 35.

  In the genre display unit 36 in the icon display unit 34, when displaying only a specific genre, not all genres, on the POI icon displayed on the map, the user instruction signal is displayed in the genre display unit 36. It is possible to select and display only the genre or the like designated by the user fetched by the fetching unit 43 and not to display it. Thereby, as described later, when a facility as an arbitrary destination is set by the destination setting unit 39 of the guidance route setting unit 38, when the genre of the facility is detected by the destination facility genre detection unit 50, It is also possible to take in the data of the genre, consider that the subsequent display of the genre is unnecessary, and not display the POI icon of the genre.

  In the distance designation display section 37 in the icon display section 34, when displaying the POI icon to be displayed on the map, for example, the POI icon of the facility of the same genre within the predetermined distance around the facility set as the destination is hidden and the guide route is displayed. Processing such as making it easier to see. In that case, when the guide route is set from the current position to the destination by the guide route setting unit 38, the same genre as the destination in the range of the guide route within a range of, for example, 500 m is set by the guide route predetermined area setting unit 51. It is possible to operate such as not displaying the POI of the facility. As described above, the process of hiding a specific type of POI icon on the genre display unit 36 and the distance designation display unit 37, together with the other hand-drawn parts shown in the figure, operate in association with each other. be able to.

  In the guidance route setting unit 38, the destination data set by various methods in the destination setting unit 39 and the data of the vehicle position detection unit 13 captured by the current location capturing unit 40, as in the conventional navigation device, Thus, the guide route calculation unit 41 calculates and presents the guide route corresponding to various conditions. Of the calculated guidance routes, the route selected and designated by the user is set as the guidance route to the destination, and the data is stored in the guidance route storage unit 42. Thereafter, the guidance route guidance unit 52 outputs a guidance image from the image output unit 21 to the monitor 20 and performs voice guidance from the voice output unit 23 through a speaker, similarly to the conventional navigation apparatus.

  The user instruction signal capturing unit 43 captures various user instruction signals input by the instruction signal input unit 17 as described above for the processing of the navigation processing unit 31, and the map as described above. In addition to outputting to the display processing unit 32 and the guidance route setting unit 38, as will be described later, taking in various signals such as outputting a user instruction signal as to whether or not to re-display the once deleted icon Output the signal.

  In the erased icon re-determining determination unit 44, for example, the genre display unit 36 of the icon display unit 34 does not display the POI icon of the same genre as the facility set as the destination, so that the guidance route can be easily displayed. As will be described later, when the destination facility use determining unit 47 determines that the destination has been reached and the facility has been used, and then the vehicle restart detecting unit 45 detects that the vehicle has been restarted, or When it is determined that the facility has not been used even if it arrives at the facility, it is determined whether or not the erased icon is displayed again by a user instruction signal. When it is determined that the erase icon is to be posted again, the icon display unit 34 displays the icon again.

  The vehicle restart detection unit 45 displays icons of the same genre as the facility at the destination within the predetermined distance range of the guidance route from the vicinity of the destination or the current location to the destination until the destination is reached as described above. If it is determined that the destination facility has been used by the destination use determining unit 47 and then the vehicle restart detecting unit 45 detects that the vehicle has been restarted, then the erase icon repost determining unit 44 Thus, it is used as a signal for determining whether or not to display again as described above.

  In the destination facility data temporary erasure unit 46, the destination facility use determination unit 47 detects that the vehicle has not stopped for a predetermined time, such as 10 minutes, even though it has detected arrival at the destination. In such a case, it is considered that the facility was closed or it was decided that it was decided not to use it because it was crowded, and after that, when trying to select a dining facility as the destination again, it was set as the previous destination The icon display unit 34 is instructed that the facility icon is not temporarily displayed as a POI icon for setting the destination so that the POI icon is not displayed again and the facility is not designated again. Output.

  In the destination facility use determination unit 47, the vehicle arrives at the destination set by the destination setting unit 39 of the guidance route setting unit 38 as described above, but the time when it is estimated that the facility has been used is stopped. When it is determined that the destination facility has not been used, it is determined that the destination facility has not been used, and when the vehicle has stopped for a predetermined time or longer, processing for determining that the destination facility has been used is performed.

  Therefore, after detecting that the destination has arrived at the destination by the destination arrival detection unit 48 by matching the destination and the current position, the destination stop time measuring unit 49 indicates that the vehicle has stopped for a predetermined time such as 10 minutes. If it is detected, it is determined that the facility at the destination is used, and when it is detected that the vehicle has been departed below, it is determined that the facility set at the destination is not used. At this time, whether or not the vehicle has started is detected by the vehicle restart detection unit 45, and the determination result is obtained by the deletion icon re-determination determination unit 44 and the destination facility data temporary deletion unit 46 as described above. Use.

  The destination facility genre detection unit 50 detects the genre of the facility at the destination set by the destination setting unit 39 of the guidance route setting unit 38. In this case, the genre data of each facility recorded on the map / information data recording medium is used for the set destination. The genre data of the destination facility is used as a genre that is not displayed on the map by the genre display unit 36 in the icon display unit 34 of the map display processing unit 32 as described above. By displaying the icon, it is possible to eliminate unnecessary icon display.

  In the guide route predetermined distance within area setting unit 51, for the guide route set by the guide route setting unit 38, an area within a predetermined distance such as 500 m from the guide route is set. The data is processed by the distance designation display unit 37 of the icon display unit 34 so that the POI icon of the facility of the same genre as the destination in the area within the predetermined distance is not displayed and the display of the evening color is easy to see. Used for.

  In the guidance route guidance unit 52, when the guidance route set by the guidance route setting unit 38 is stored in the guidance route storage unit 42 as described above, guidance is provided so that the vehicle can easily travel along the guidance route. This is the same as the conventional navigation device.

  As described above, the present invention comprising the functional blocks shown in FIG. 1 can be implemented by, for example, sequentially operating according to the operation flow shown in FIG. In the example of the POI icon display processing corresponding to the destination setting shown in FIG. 2, first, the destination setting is selected by displaying the POI icon (step S1).

  That is, when setting the navigation route of the navigation device, when selecting a destination, the destination is conventionally selected by various means using an address, a telephone number, a scroll of the map, a POI mark displayed on the map, a nearby landmark, and the like. However, according to the present invention, the POI icon display is particularly effective when the user designates an arbitrary icon in the POI icon display to set the destination. However, in the present invention, when the destination is set by various methods, various destination setting methods can be used if the genre of the facility can be detected.

  Next, in the example of FIG. 2, all POI icons are displayed on a map including the vicinity of the destination. That is, in the example of FIG. 2, since the user has selected a destination setting method based on the POI icon display in the step S1, the vicinity of the destination is included on the current map in order to execute the method. However, if the area around the destination is not included, the map including the area around the destination is displayed by scrolling the map.

  Thereafter, in a state where all POI icons are displayed on the map around the destination as described above, the user designates an appropriate icon from among the icons and sets the facility as the destination (step S3). In that case, by the function of the proximity sensor of the touch panel, when the user brings a finger or the like close to the POI icon of the facility using a specific icon as an instruction, the facility name of the facility is displayed by a balloon display on the screen. By displaying the genre, business details, etc., the user can confirm it and actually touch the POI icon, so that the user can definitely designate a specific facility as the destination.

  FIG. 3A shows a state where all POI icons are displayed on the map as described above, and an arbitrary facility is set as the destination. The icons shown in FIG. 3A are icons of facilities of each genre of “meal restaurant”, “coffee shop”, “snack”, “convenience store”, and “gas station”, as shown in an enlarged view in FIG. In particular, regarding the genre of “meal restaurant”, “family restaurant”, “ramen”, “soba”, and “general cafeteria” as other restaurants are reclassified and POI icons are displayed. Therefore, in the present invention, regarding the genre of “meal restaurant”, the reclassified facility as described above can also be handled as a genre.

  In the example of FIG. 3 (a), a state where this facility is set as a destination is indicated by instructing one of the “ramen restaurants” of “restaurant” with the POI icons of all facilities displayed. In the example of FIG. 2, the process proceeds to step S4, and the genre of the facility at the destination set as described above is detected. Here, as described above, the genre of “meal restaurant” is detected.

  The above operation is performed by the destination input icon display unit 35 of the icon display unit 34 in a state where a desired position map is displayed on the map display unit 33 in the map display processing unit 32 of the location processing unit 31 in FIG. All POI icons are displayed, and the POI icon facility designated by the user in the user instruction signal capturing unit 43 is set as the destination in the destination setting unit 39 of the guidance route setting unit 38. ing.

  Thereafter, the process proceeds to step S5, and icons of the same genre as the destination are deleted. In this case, as described above, the genre of the destination is “meal restaurant”, and as long as it is decided to eat at the destination, it is almost impossible to eat at least at other facilities near the destination. Therefore, for example, it is assumed that the POI icon display of the “dining place” facility within the range of 500 m around the destination is not necessary, and it is erased from the map screen and is not displayed. This state is shown in FIG. 4A, and the POI display of the “dining place” within a predetermined distance of, for example, 500 m around the destination is not performed. As a result, the display of the POI icon at least near the destination is reduced, and the state of the road near the destination becomes easy to see, and the destination can be easily reached.

  In step S5, when the POI icon of the same genre as the destination is deleted, the destination from the current location other than the rejection of the POI icon of the same genre as the destination within the predetermined distance from the destination as described above. A POI icon of the same genre as the destination may be prevented from being displayed within a predetermined distance such as 500 m along the guidance route to the ground.

  In other words, when a “meal restaurant” facility is set as the destination as described above, in many cases, there is no meal between the current location and the destination. A POI icon of a genre of “meal restaurant”: within a predetermined distance along the route is not displayed. As a result, as shown in FIG. 4B, the “dinner” icon along the guidance route from the current location to the destination is erased, making it easy to see all the guidance routes.

  In this operation, after setting the destination as described above in the destination setting unit 39 of the guidance route setting unit 38 as described above, the destination facility genre detection unit 50 in FIG. 1 detects the genre of the destination facility. Then, the genre display unit 36 in the icon display unit 34 of the map display processing unit 32 stores the data for a genre of the destination facility within a predetermined distance from the destination or a predetermined route from the current location to the destination. This is done by not displaying the POI icon of the same genre as the destination facility within the distance range.

  In the example of FIG. 2, after arriving at the destination in this way, it is determined whether or not the vehicle has stopped for a predetermined time such as 10 minutes (step S7). When it is determined that the vehicle has stopped for a predetermined time or longer, the process proceeds to step S8, where it is determined whether or not the vehicle has been restarted.

  When the vehicle is restarted after that, that is, when it arrives at the destination and performs at the destination, it can be assumed that the vehicle has departed. For example, when the vehicle is restarted after a predetermined time of at least 10 or the like has elapsed at the destination In step S9, the user is inquired as to whether or not to display the POI icon of the destination genre detected earlier.

  In this case, for example, as shown in FIG. 3 (a), an inquiry display such as “Do you want to redisplay surrounding icons” on the map screen, and “Do not redisplay” and “Redisplay” input. A screen is displayed, and a user can make a selection input by touching one of them. In the example shown in the figure, after the departure from the destination “G”, the POI icon of the same genre as the destination in the town area within the predetermined distance from the destination is not displayed yet. It is carried out.

  In FIG. 2, after that, in step S10, it is determined whether or not the user has instructed to display the POI icon of the genre, that is, the genre of the facility set as the destination. ! Proceed to display all the POI icons of the genre of the icon.

  In these operations, after the arrival at the destination is detected by the destination arrival detection unit 48 of the destination facility use determination unit 47 in FIG. 1, the time from the arrival at the destination is measured as the stop time of the destination. When the time measured until the vehicle is restarted by the vehicle restart detection unit 45 is detected by the vehicle restart detection unit 45 when it is detected that the vehicle has stopped for a predetermined time or longer enough to be used at the destination, the inquiry screen as described above is displayed. The deletion icon re-display discriminating unit 44 captures the user instruction from the user instruction signal capturing unit 43, and displays all the POI icons previously erased again by the genre display unit 36 of the icon display unit 34. It is done by. As a result of such processing, as shown in FIG. 4B, all the icons including the facility set as the destination are displayed.

  On the other hand, in step S7 of FIG. 2, after arriving at the destination, the vehicle departs before a predetermined time such as 10 minutes elapses, or passes through the destination as it is without stopping at the destination at all. L) When it is determined that the vehicle has traveled more than this time, it is determined that the vehicle has not stopped at the destination for a predetermined time or more, and the process proceeds to step S12, and the data of the facility set as the destination is deleted for a predetermined period such as one day.

  That is, when the vehicle arrives at the destination without stopping for the time it takes to reach the destination, or when it arrives at the destination and passes through as it is, the user is the destination. For example, when you arrive in front of a ramen shop, when you know that today is a holiday, or when you find that customers to enter the store are in a long line, such as Sometimes, to avoid using the facility at least that day, the facility data itself is erased, and then when searching for further destinations, the facility is displayed again on the destination selection screen. So that there is no such thing.

  This operation is performed by the erase icon re-determining section shown in FIG. 1 that the vehicle has not stopped for a predetermined time even when it arrives at the destination. When it is detected that the vehicle has not stopped for more than an hour, the destination facility data temporary deletion unit 45 temporarily deletes the data of the destination facility.

  As a result of performing the operation as described above, as shown in FIG. 5A, a POI icon redisplay inquiry screen is displayed when the vehicle departs after a predetermined time elapses after arrival at the destination, where the user “redisplays”. When an instruction to this effect is given, as shown in FIG. 5B, the POI icons of all facilities including the POI icons of the facilities previously set as the destination are displayed. On the other hand, on the screen shown in FIG. 6A, when the instruction “select not to be redisplayed” is selected, the genre of the facility set at the previous destination is newly displayed without being displayed. It is also possible to display the guidance route to the destination etc. in an easy-to-see manner.

  For example, as shown in FIG. 6, the same inquiry screen as in FIG. 5 (a) is displayed when the vehicle passes without stopping for a predetermined time (t) or more than a predetermined distance (L). When an instruction to “redisplay” surrounding POI icons is given here, the POI icons are redisplayed as shown in FIG.

  However, on this screen, it is determined that the facility that was previously set as the destination as described above was not used for some reason, such as the store was found to be closed, and again In order not to display the facility at the destination, the data of the facility itself is deleted for a predetermined period such as one day. FIG. 6B shows such a state, and here, an example is shown in which a POI icon reprinted is seen and a nearby facility in the same genre as a destination is set as a new destination. ing. Even if they are placed individually, when a specifier gives an instruction to select “Do not redisplay” surrounding icons, the POI icon will not be displayed for facilities of the same genre as the facility set at the destination. Is the same as in the previous case.

  In the present invention, since the POI icon is displayed by performing the above-described processing, it is possible to prevent the route to the destination from becoming difficult to see by displaying a large number of icons on the map, When searching for a destination again when the destination is not used, the previous destination can be kept from being displayed, and the navigation device can be easily used.
