JP 2011-33543 A

  In general, it's nice to have more of your favorite facilities, and I feel very happy if the accidental facilities match my preferences. In addition, even in a facility that has been in the past, a new service has started or a product that has not been handled until now starts to be treated, and as a result, the facility may become a new favorite facility. This is also nice for the user.

  In Patent Document 1, when the guide branch point is close, the above-described guide plate is displayed. Since the name of a plurality of facilities along the advancing road extending from the guidance branch point is indicated on the guide plate, there is a facility indicated on the guidance plate when traveling along the advancing road. I understand that.

  However, even if the facility name that is text information is indicated by the guide plate, it is difficult for a user who does not know the facility to determine what the facility is from the facility name. The facility genre may be known depending on the facility name (for example, XX park, etc.), but it is not possible to make a specific judgment based on the facility name such as how it differs from other facilities of the same genre. For this reason, even if the navigation device of Patent Document 1 is used, it is not easy to find a new facility that is his / her favorite.

  Also, if you are going to a facility that is in a range that is far from your range of action, you often plan ahead. When you are driving while looking for a new favorite facility, it is normal to think that you want to find a facility that is slightly out of your range of action or that range of action, and up to facilities that greatly deviate from the range of action Usually not intended.

  However, in patent document 1, a guide plate is displayed with respect to all the roads which can advance in a guidance branch point. Therefore, the guide plate is also displayed in a direction that greatly deviates from the action range for the user. As a result, the user may be guided in a direction greatly deviating from the user's action range. In this respect as well, the navigation device of Patent Document 1 is difficult to use for finding a facility that is his / her favorite.

  The present invention has been made based on this situation, and an object of the present invention is to provide a facility information display device that allows a user to easily find a facility that is a favorite of the user.

The first invention for achieving the object includes a display unit (20) for displaying a road map, current position acquisition means (40 S1, S7) for acquiring the current position, and the current position acquired by the current position acquisition means. Based on the position and the road map data, the guidance branch point determination means (40 S2) for determining the guidance branch point to perform next guidance, the area that is determined based on the user's action range, and A facility feature graphic that represents a feature that is distinguishable from a facility of the same facility genre as a new facility for the user that is a facility that includes a travelable road that enters after passing through a guidance branch point. Facility feature figure acquisition means (40 S3, S4) and direction information map creation means (40 S5, S) that creates a direction information map including at least one of the facility feature figures for each travelable road. 6) and display control means (40 S8-S10) for displaying the direction information map together with the road map on the display unit based on the fact that the current position has reached the display start position determined based on the guidance branch point. The facility feature graphic acquisition means (40 S31) presets an area determined based on the user's action range from the user's action range and the action range outside the action range. The direction information map creating means (40 S6) determines that the new facility corresponding to the facility feature graphic included in the direction information map is outside the user's range of action. If a facility is located, the display facility information, characterized in that to create the surface information view in a manner that can be seen that the new facility is located in the area outside the activity range of the user It is the location.
The second invention includes a display unit (20) for displaying a road map, current position acquisition means (40 S1, S7) for acquiring the current position, and the current position and road map data acquired by the current position acquisition means. Based on the guidance branch point determination means (40 S2) for determining the next guidance branch point for guidance based on the area determined based on the user's action range and after passing through the guidance branch point Facility feature graphic acquisition means (40) for acquiring a facility feature graphic that represents a feature that is distinguishable from a facility of the same facility genre as the new facility for a facility that includes a travelable road to be entered and that is new for the user. S3, S4), direction information map creation means (40 S5, S6) for creating a direction information map including at least one of the facility feature figures for each of the travelable roads, and the current position is the above-mentioned plan A display control means (40 S8-S10) for displaying the direction information map on the display unit together with the road map based on reaching a display start position determined based on an inner branch point; The graphic acquisition means (40 S34) acquires the facility characteristic graphic as one of the new facilities for the user for the facility that the user has not visited, and the direction information diagram creation means adds the facility information graphic to the direction information map. The facility information display device includes a facility graphic that has been visited by the user in a smaller number than a facility characteristic graphic corresponding to a facility that has not been visited by the user.

According to these inventions, when approaching the guidance branch point, a direction information map including at least one facility feature graphic is displayed on the display unit. Since the facility feature graphic is information that can be distinguished from facilities of the same genre, it is possible to determine whether or not to try even if the facility is a new facility.

  In addition, when trying to distinguish the facility from facilities of the same genre by characters, a large number of characters are required, and the burden on the user to understand it becomes great. Therefore, the user can easily understand the meaning of the facility feature graphic in a short time. Accordingly, even if the user is a new facility, the user can easily and quickly determine whether the facility indicated by the facility feature graphic is likely to become his favorite facility.

  In the present invention, when approaching a guidance branch point, a direction information map that includes at least one facility feature graphic of a new facility for the user and is created for each travelable road is displayed on the display unit. Therefore, even in a situation in which a guidance branch point is approaching and determination in a short time is required, the user can determine the direction in which a new facility that is likely to be his / her favorite exists. As a result, the user can easily find a new facility that is his / her favorite.

  Furthermore, since the facility in which the facility feature graphic is displayed is a facility that exists in an area determined based on the user's action range, the facility feature graphic for a facility that greatly deviates from the user's action range is not displayed. That is, the facility feature graphic for the facility where the user is unlikely to go is not displayed. Therefore, it is possible to prevent the user from being guided to an unintended facility. This also makes it easier for the user to find a new facility that is his / her favorite.

It is a block diagram which shows the structure of the vehicle-mounted navigation apparatus 1 provided with the function as an action proposal apparatus of this invention. It is a figure which shows notionally the road map and the own vehicle position mark 70 which are displayed on the display part 20. FIG. It is a flowchart which shows the process at the time of displaying a direction information map. It is a flowchart which shows the process of FIG.3 S3 in detail. It is a figure explaining the process by step S31, S32 of FIG. It is a display example of the direction information diagram 100 displayed in step S9 of FIG. It is an enlarged view of the direction information diagram 100.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, a navigation device 1 having a function as a facility information display device of the present invention is mounted on a vehicle, and includes a storage unit 10, a display unit 20, a GPS receiver 30, a navigation ECU 40, and a radio device 50. Prepare.

  The storage unit 10 includes a writable storage medium. This storage medium stores road map data. The road map data includes a node indicating a road shape, a link, various costs for each link (distance cost, time cost, etc.), and various information about the facility (hereinafter, facility information). The facility information includes a facility name, a facility position, a facility genre, and the like. Moreover, it is preferable that the facility characteristic figure mentioned later is also included. The storage unit 10 also stores a vehicle movement history that is used as a user's behavior history.

  A road map is displayed on the display unit 20. In addition, a mark indicating the vehicle position (hereinafter, vehicle position mark) 70 is displayed on the road map (see FIG. 2). Further, when the vehicle position is close to the guidance branch point, the display unit 20 shows a direction information diagram 100 (FIG. 6, which shows information related to facilities existing in the direction in which the vehicle can travel through the guidance branch point. 7) is superimposed on the road map. Details of the content information map 100, the number of displays, and the display timing will be described later.

  The GPS receiver 30 receives a signal transmitted from a GPS artificial satellite, and sequentially determines the coordinates of the current position based on the received signal. The wireless device 50 performs wireless communication with the outside of the vehicle and receives various information. The received information includes, for example, facility information of a newly created facility, information indicating the start of a new service at an existing facility, and information on a product that has been newly handled.

  The navigation ECU 40 includes a CPU that performs various arithmetic processes, a ROM and flash memory that store programs used for the arithmetic processes, and a RAM that functions as a calculation work area. In addition, an input / output interface for exchanging data with an external device and a bus for connecting them are also provided. The processes executed by the navigation ECU 40 include a read / write process of the storage unit 10 and a display process of the display unit 20. The navigation ECU 40 sequentially acquires the current position determined by the GPS receiver 30. And navigation ECU40 displays the road map and the own vehicle position mark 70 on the display part 20 based on the acquired various information. FIG. 2 conceptually shows the road map and the vehicle position mark 70 displayed on the display unit 20.

  Moreover, navigation ECU40 memorize | stores the present position in the memory | storage part 10 one by one. That is, the navigation ECU 40 also performs a process of sequentially updating the movement history. The movement history is created and updated for each user when the user (that is, the driver) can be identified.

  Furthermore, the navigation ECU 40 of the present embodiment also performs processing for displaying the above-described direction information map 100. Next, processing executed by the navigation ECU 40 to display the direction information map 100 will be described with reference to FIG. The navigation ECU 40 periodically executes the process shown in FIG.

  Step S <b> 1 is a process corresponding to the current position acquisition unit, and acquires the current position from the GPS receiver 30. Step S2 is processing corresponding to the guidance branch point determination means, and determines the guidance branch point. The guidance branch point is a branch point that displays the direction information map 100 described above. The guidance branch point is the closest branch point among the branch points existing ahead in the traveling direction of the host vehicle on the road on which the host vehicle is currently traveling. However, when the road branched at the branch point is a narrow road, the guide branch point may be determined by excluding the branch point.

  In step S3, it is determined which facility feature graphic 101 (see FIGS. 6 and 7) of which new facility is included in the direction information diagram 100. Details of this processing are shown in FIG.

  In steps S31 and S32, the area for extracting the facility for displaying the facility feature graphic 101 is narrowed down. In step S31, the above-mentioned area is first narrowed down to an area based on the user's action range. The action range is determined based on the movement history stored in the storage unit 10. For example, a link having a movement history is set as an action range. In addition, you may limit the movement log | history which determines an action range to the past fixed period. This action range can be identified by the user, and is determined for each user when there is a movement history for each user.

  In this step S31, the area for extracting the facility for displaying the facility information is narrowed down to the links that are the action range and the area that can be reached with the number of links determined in advance from each link. Hereinafter, the narrowed area is referred to as a primary narrowed area.

  Some facilities that are outside the range of action, but that are slightly beyond the current range of action by expanding the primary narrowing area to the range that can be reached with the number of links determined in advance from each node as the action range The facility feature graphic 101 can be displayed.

  In addition, it is good also considering the circle | round | yen of the predetermined action radius centering on a home as an action range, without using a movement history. In this case, the area for extracting the facility for displaying the facility feature graphic 101 is within a circle having a radius obtained by adding a certain length to the action radius. The reason why a certain length is added is that a facility that is slightly beyond the current action range is also a facility that displays the facility feature graphic 101.

  FIG. 5 exemplifies area narrowing by step S31 and step S32 described next. In FIG. 5, reference numeral 80 denotes a guidance branch point. In FIG. 5, the primary narrowing area is shown by a polygon combining vertical and horizontal lines that are orthogonal to each other. However, this is for the convenience of drawing, and can be reached with a predetermined number of links from each link as the action range. It is a conceptual representation of the range. The primary narrowing area may be circular.

  In step S32, the area narrowed down in step S31 is further narrowed. Specifically, the primary narrowing area is narrowed down to an area that can be reached from the guidance branch point at a time cost or distance cost that is less than or equal to a preset upper limit cost. Further, the guidance branch point 80 is used as a reference point, and the area is narrowed down to an area of a predetermined angle range (for example, 45 degrees) on both sides of the advancing road 90 that can enter the guidance branch point 80 from the current position. In FIG. 5, the area narrowed down by the upper limit cost is shown as a circle, but this is also for convenience of drawing, and the area narrowed down by the upper limit cost is not necessarily a circle in practice.

  The reason why the area is narrowed down by the upper limit cost is that even if the facility can be reached via the travelable road 90, the user is unlikely to go to a distant facility. Further, the reason for narrowing down the angle is to exclude the road and the area in the vicinity of the road that has been reached before reaching the guidance intersection. As a result of the processing in steps S31 and S32, in the example of FIG. 5, the hatched area is an area for extracting the facility displaying the facility feature graphic 101.

  In step S33, the facility which exists in the area narrowed down by the process of step S31 and S32 is extracted. In step S34, the facilities extracted in step S33 are narrowed down to facilities corresponding to the new facility. This new facility is new to the user, and corresponds to a new facility if the user has not visited the facility. In addition, even if the service and handling products in the facility are new to the user, it corresponds to a new facility. Of course, this is a new facility, and not only this user but also a new facility corresponds to the new facility here.

  Whether or not the user has not visited the facility is determined based on the movement history stored in the storage unit 10. Whether the service and products handled at the facility are new to the user is determined based on the travel history, when the facility was last visited, when the service was started at the facility, and when the new product was started To be determined.

  In step S <b> 35, the facilities narrowed down in step S <b> 34 are further narrowed down to facilities that can acquire the facility feature graphic 101. The facility characteristic graphic 101 is a graphic that can distinguish the facility from other facilities of the same genre, and the graphic here does not include a graphic consisting of only characters. Therefore, the facility feature graphic does not include only the facility name represented in characters. On the other hand, photographs are included in figures. In addition, since a figure partially including characters is not only a character, it is included in the figure here. Moreover, since the facility can be distinguished from other facilities of the same genre, map symbols are not included.

  Examples of the facility feature graphic include a photograph of the facility and a facility mark. If the facility is a building, the photograph of the facility may be a photograph of the inside of the building as well as a photograph of the exterior of the building. The appearance photograph may be a partial photograph instead of the entire appearance. The photograph in the building may not be a photograph of the building itself but a photograph of furniture in the building. The facility mark is preferably a mark indicating only the facility, but may be a mark common to a plurality of facilities such as a chain store mark. This is because a chain store mark can be distinguished from facilities other than chain stores of the same genre.

  The facility feature graphic may be stored in a storage device included in the navigation device 1 such as the storage unit 10, or may be acquired from an external server or the like each time using the wireless device 50. In step S35, it narrows down to the facilities which can acquire a facility characteristic figure from either apparatus.

  In step S36, the facilities passing through the congested road are excluded from the narrowed down facilities. Which road is a traffic jam road is determined by acquiring current traffic jam information from the outside via the radio device 50. However, a frequently congested road may be stored in the road map data in advance, and the stored road may be a congested road here.

  In step S37, the number is further limited to a prescribed number for each possible road. The prescribed number is a number set in consideration of the fact that the visibility decreases when too large, and the amount of information is insufficient when too small, for example, 3 to 4. However, in this embodiment, the figure of the facility with the visit history is added in the later processing, and the direction information diagram 100 is created with figures and the like regarding the four to five facilities in total. When the figure of the facility with the visit history is not added, the specified number here may be larger than the above number.

  Various conditions can be used as conditions for narrowing down to the specified number. For example, it is possible to narrow down by the condition that the genre is different from the genre of the facility visited in the past. The genre of the facility visited in the past is determined from the action history and the facility information included in the road map data. Contrary to the above example, if it can be determined that a facility of the same genre has been visited frequently in the past, it may be narrowed down to facilities belonging to that genre.

  Moreover, you may mix the facility of the genre different from the genre of the facility visited in the past, and the facility of the genre visited frequently. Moreover, you may narrow down in order of the distance from a guidance branch point instead of a facility genre. Or you may narrow down in order of distance after narrowing down by genre. Alternatively, a predetermined number of facilities may be simply selected at random.

  In the example of FIG. 5, by the process of step S <b> 37, the specified number of facilities are narrowed in the direction from the guidance branch point 80 to the travelable road 90 </ b> A, that is, the right turn direction, and from the guidance branch point 80, the travelable road 90 </ b> B, that is, the left turn direction. It is done. However, in the example of FIG. 5, there is almost no hatched area in the direction passing through the travelable road 90 </ b> C that travels straight from the guidance branch point 80. Therefore, few (or none) of the facilities that exist in the straight direction are extracted.

  When the number has been narrowed down to the prescribed number in step S37, the process returns to FIG. 3 and step S4 is executed. In step S4, the facility feature graphic 101 of each new facility determined in step S3 is acquired. Steps S3 and S4 correspond to facility feature graphic acquisition means.

  Subsequent steps S5 and S6 correspond to a direction information diagram creating means. In step S5, a prescribed number of facility feature graphics 101 of facilities with a visit history are acquired, and either one or both of the home and departure locations are also acquired. The prescribed number for the facility feature graphic 101 of the facility having a visit history is smaller than the prescribed number for the new facility (step S37 in FIG. 4), for example, 1.

  There are many facilities with a visit history, but facilities with a visit history are also facilities in the area narrowed down in steps S31 and S32. Even if it is limited within the above-mentioned area, many facilities will remain, but this facility is a facility for giving a sense of security by presenting a facility known to the user. Therefore, a facility having a high number of visits or a high visit frequency is selected within a certain period in the past.

  If at least one of the facilities determined in FIG. 4 is a new service or product and has a visit history, that facility is added to the facility with the visit history in step S5. May be.

  The home and the departure place are also presented for the purpose of giving the user a sense of security. Therefore, either one is good. When the home is the departure place, only one of the figures is displayed.

  In step S6, a direction information diagram 100 is created in which the figures acquired in step S4 and step S5 are grouped for each possible road. An example of this direction information diagram 100 is shown in FIG.

  FIG. 7 shows two direction information diagrams 100A and 100B. The direction information diagram 100A is a diagram in which four facility characteristic figures 101A to 101D respectively corresponding to the facilities A to D are surrounded by the same frame 102. The facility feature graphic 101A is a photograph of the product sold at the facility A, the facility feature graphic 101B is a photo of the menu provided at the facility B, the facility feature graphic 101C is a mark of the facility C, and the facility feature graphic 101D is the facility D It is an appearance photograph. These facility characteristic figures 101A to 101D are arranged from the guidance branch point 80 side on the map in the order of the distance between the corresponding actual facility and the guidance branch point.

  An adventurer's figure (hereinafter simply referred to as an adventurer) 103 is superimposed on the upper left of the facility characteristic figure 101A. The adventurer 103 indicates that the facility is outside the action range. By displaying the adventurer 103 superimposed on the facility feature graphic 101A, the user can know that the facility A is out of the action range, and the action toward the facility A is a small adventure that slightly expands the action range. You can know that there is. However, the mode indicating that the facility is outside the action range is not limited to the adventurer 103, and may be a person in another form. Further, as long as the display mode can be distinguished from the facility feature figure 101 in the action range, such as making the frame color or the internal color of the facility feature figure 101 different from the facility feature figure 101 in the action range, other modes But you can.

  In addition, the facility feature figures 101A to 101D do not distinguish whether the facility has a visit history or not in the display mode. However, these may be displayed in a distinguishable manner. For facilities with a visit history, the facility name may be displayed in characters instead of the facility feature graphic 101.

  Next, the direction information diagram 100B will be described. The direction information diagram 100B is a diagram in which two facility characteristic figures 101E and 101F corresponding to the facilities E and F, respectively, and a home figure 104 are surrounded by the same frame 102. The facility feature graphic 101E is a photograph of a product sold at the facility E, and the facility characteristic graphic 101F is a photograph of the facility F in the store. The facility characteristic figures 101E and 101F and the home figure 104 are also arranged on the map from the guidance branch point 80 side in the order of the distance between the corresponding facilities E and F and home and the guidance branch point.

  Note that the home or departure place may not exist within the area determined in FIG. In this case, the graphic indicating the home or the departure place may not be displayed, but the home or the departure place does not exist in the above area, but corresponds to the direction most suitable for going to the home or the departure place. The direction information map 100 may include a graphic of a home or departure place.

  In addition, the facility feature graphic 101E shows “NEW” indicating that the facility is a newly created facility. As a result, it can be seen at a glance that it is a new facility. Since there are many people who want to go to a new facility, the usefulness of the direction information map 100 is improved by displaying such information.

  In addition, the direction information map 100B has fewer facility feature figures 101 than the other direction information map 100A. The direction information map 100B does not include the facility feature graphic 101 for facilities outside the action range, and the travelable road 90B corresponding to the direction information map 100B is the direction toward the home. In other words, in the present embodiment, the direction information diagram 100A including the facility feature graphic 101A for the facility outside the action range is more of the facility feature graphic 101 than the direction information diagram 100B not including the graphic. The number is increasing. Since a lot of information is shown for the direction toward the outside of the action range, the user is more likely to select the direction toward the outside of the action range. Thereby, the user can expand the action range without being conscious. In contrast to this, a lot of information may be indicated for the direction toward the action range. In this case, the knowledge about the facility within the action range can be increased. Moreover, you may make the number of the facility information figures 101 included in the direction information map 100 the same, without considering whether it is the direction which goes out of the action range.

  In step S6 of FIG. 3, the direction information diagram 100 illustrated in FIG. 7 is created. For this purpose, the distance between the facility corresponding to the graphic such as the facility characteristic graphic acquired in steps S4 and S5 and the guidance branch point is calculated, and information on whether or not the facility is a new facility is obtained. To get through. The period after the establishment of the facility that determines whether or not the facility has been newly established is set in advance, for example, about 1 to 3 months.

  In step S7, the current position is acquired again from the GPS receiver 30. Steps S8 to S10 correspond to display control means. In step S8, it is determined whether the current position acquired in step S7 has reached a display start position that is a predetermined distance before the guidance branch point determined in step S2. If this judgment is NO, it will return to Step S7.

  If YES in step S8, the process proceeds to step S9, and the direction information map 100 created in step S6 is shown on the road map displayed on the display unit 20 as the direction information map 100 at which guide branch point 80. In this manner, the direction information diagram 100 is displayed.

  FIG. 6 shows a display example of the direction information diagram 100 displayed in step S9. In the example of FIG. 6, the direction information map 100 </ b> A and the direction information map 100 </ b> B are arranged at positions overlapping the travelable roads 90 </ b> A and 90 </ b> B in the enlarged view in which the guidance branch point 80 and its vicinity are enlarged.

  By displaying the direction information map 100 in this way, what kind of facility is present when proceeding to the right at the guidance branch point 80 and what kind of facility is present when proceeding to the left. Can understand immediately. You can also see that if you go to the left, you can go home. The crosses in FIG. 6 indicate that the direction is out of the action range. This x mark is displayed when a new facility is not extracted in the process of step S3. In addition, when the distance from the guidance branch point 80 on the travelable road 90C to the exit of the primary narrowing area is a specified distance, this x mark may be displayed without performing the process of step S3. Moreover, you may show not only a * mark but deviating from the action range in another aspect.

  FIG. 7 described above is a partially enlarged view of FIG. In step S9, if the facility corresponding to the facility feature graphic 101 included in the direction information map 100 is within the display range of the road map that is not an enlarged map, the facility feature graphic included in the direction information map 100 is displayed. 101 is also displayed on a road map that is not an enlarged view. Thereby, the facility indicated by the facility feature graphic 101 can be easily reached. Alternatively, the route guidance to the facility indicated by the facility feature graphic 101 may be started by selecting and operating the facility feature graphic 101 included in the direction information map 100.

  In step S10, after passing through the guidance branch point 80, the display of the direction information map 100 is deleted. After that, it returns to step S1 again. Therefore, the next guidance branch point 80 is determined and a new direction information map 100 is created. When the guidance branch point 80 approaches, the newly created direction information map 100 is displayed.

  Since this process is repeated, each time the display unit 20 approaches the guidance branch point 80 that is sequentially set forward in the traveling direction, what kind of facility is in the direction that can proceed at the guidance branch point 80, The display form is an intuitively understandable graphic form. Therefore, it is possible to easily determine which direction to go at the guidance branch point 80 even when traveling on the road where the display unit 20 cannot be seen for a long time.

  As described above, according to the present embodiment described above, when approaching the guidance branch point 80, the direction information diagram 100 including at least one facility feature graphic 101 is displayed on the display unit 20. Since the facility feature graphic 101 is information that can be distinguished from facilities of the same genre, it is possible to determine whether or not to try even if the facility is a new facility.

  Moreover, if it is going to distinguish the facility from the facility of the same genre by a character, many characters will be required and the burden of the user for understanding it will become great. However, in this embodiment, since the facility feature graphic 101, that is, the facility feature is indicated by the graphic, the user can easily understand the meaning of the facility characteristic graphic in a short time. Accordingly, even if the user is a new facility, the user can easily and quickly determine whether or not the facility indicated by the facility feature graphic 101 is likely to become his favorite.

  When approaching the guidance branch point 80, the direction information map 100 created for each possible road is displayed on the display unit 20, so that the user is approaching the guidance branch point 80 and is required to make a judgment in a short time. Can determine the direction of new facilities that are likely to become their favorite. As a result, the user can easily find a new facility that is his / her favorite.

  Furthermore, since the facility in which the facility feature graphic 101 is displayed is a facility that exists in an area determined based on the user's action range, the facility feature graphic 101 for a facility that greatly deviates from the user's action range is not displayed. . That is, the facility feature graphic 101 for facilities that are unlikely for the user to go is not displayed. Therefore, it is possible to prevent the user from being guided to an unintended facility. This also makes it easier for the user to find a new facility that is his / her favorite.
