The main controller 16 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc., reads map information from the map database 13 and displays it on the display unit 14 including a liquid crystal display panel. At the same time, necessary information is notified from the voice output unit 15 to the user as appropriate.

  The spot information processing unit 18 includes a spot information registration unit 19, a spot information search unit 20, and a spot information content display unit 21. When arbitrary point information is input from the input unit 11, the point information registration unit 19 stores this point information in the main memory 17.

  Further, when the user wants to refer to the spot information stored in the main memory 17, the spot information search unit 20 corresponds to this keyword when the keyword of the spot information to be referred to is input by the input unit 11. The point information is extracted from the main memory 17 and the extracted result is displayed on the display unit 14.

  The point information content display unit 21 determines the point information to be displayed when displaying the point information on the display unit 14 based on the state of the list to be displayed, the scale of the displayed map, the position of the host vehicle, the traveling direction, and the like. The contents of are to be changed.

  FIG. 2 is a diagram showing a memory structure of point information stored in the main memory 17 by the point information registration unit 19. In FIG. 2, the spot information stored in the main memory 17 takes the configuration of the memory arrangement 31 on the main memory 17, and the spot information a, spot information b,. Stored in order.

  Further, image information regarding each piece of point information arbitrarily input by the user is stored in the order of image information α, image information β,. Note that the image information and the point information do not need to be paired, and the image information does not necessarily exist.

  Further, the data content of the spot information “a” includes a spot name “a”, position information “a”, spot mark “a”, group attribute “a”, information rank “a”, text information “a”, pointer “a” to image information “α”, and the like. Here, the group attribute a is data for associating each piece of point information with each other, and can be arbitrarily set by the user regardless of the genre of the facility and the existing location. The information rank a is data used when displaying arbitrary point information on the display unit 14.

  In the present embodiment, each piece of point information a, b... Is stored in the main memory 17 from the point information registration unit 19 by associating it with specific related information comprising group attributes and information ranks (importance). When a specific group attribute is specified from the input unit 11, the point information search unit 20 searches and acquires all the point information related to the group attribute stored in the main memory 17. .

  FIG. 3 is a diagram showing a display example of the display unit 14 in which a plurality of pieces of spot information are registered at exactly the same place. In FIG. 3, a map screen is displayed on the display unit 14, and a registered building 32 is displayed on the map screen.

  In the XX building 32, there are five pieces of point information 37 in which the group attributes are set in association with the XX building, and the XX building 32 is used as the point information of the information rank 1 as the point information of the information rank 1. Meal 33 and ΔΔ (gym) 34 are registered as □□ (Chinese food) 35 and XX (Japanese food) 36 as point information of information rank 3.

  Among the pieces of point information belonging to the XX building 32, the XX building 32 having the highest information rank is displayed on the screen as a representative point. When it is desired to refer to other point information, the point information 33 to 36 can be easily obtained by using the group attribute from the XX building 32. The same applies to the representative point having the lowest information rank. Note that the information rank to be displayed may be selected by the user in addition to the point information system automatically determining.

  Next, the spot information registration process by the spot information registration part 19 is demonstrated based on the flowchart of FIG. First, when the user presses the point information registration button provided in the input unit 11, the point information registration process is started (step S1), and the process is repeated for the number of pieces of point information data (step S2). Next, the user inputs each data item using the input unit 11 and the HMI (step S3).

  Regarding the input method, use any method such as creating according to the input form, specifying the position from the map, creating by referring to the index data, or creating by handwriting input. .

  If the number of pieces of point information remains, the process returns to step S2 to input the next data (step S4). When the input of each data is completed, the image information is input (step S5). The input image information is stored in the point information registration unit 19 as image data in bitmap format or JPEG format (step S6), and then a pointer to the memory storage area start address of the stored image information is acquired. (Step S7).

  Next, the pointer of the acquired image information and the already input point information are stored in the main memory 17 (step S8), and the point information registration process is ended (step S9).

  Next, group attribute registration processing will be described based on the flowchart of FIG.

  First, when the group attribute registration process is started (step S11), the user selects whether to create a new group attribute (step S12). When a new group attribute is created in step S12, a name unique to any group attribute is created (step S13). Here, it is also possible to create a point mark specific to the group attribute.

  Also, when using an existing group attribute in step S12, the group attribute already created is acquired and displayed in a list (step S14), and then the user is determined to be appropriate from the group attributes displayed in the list. The determined arbitrary group attribute is selected (step S15).

  When the number of group attributes to be set in the spot information is determined as one, the corresponding group attribute is set (step S16), and the group attribute registration process is terminated (step S17). Although the group attribute registration process has been described here, the same applies to the change process.

  Next, the point information search process will be described based on the flowchart of FIG.

  When the user wants to refer to the registered spot information, the spot information search process is started (step S21). The user inputs an appropriate search condition (keyword) from the input unit 11 in order to extract target point information (step S22). As a search condition, a telephone number, a name, an address, a genre, a group attribute, a point mark, or the like is used as in the case of searching for normal facility information.

  Next, point information that matches the search condition specified by the user is extracted (step S23). The spot information search unit 20 extracts all other spot information belonging to the extracted spot information group (step S24), and ends the process (step S25). At this time, the spot information content display unit 21 determines a display format from the data contents of the spot information extracted by the spot information search process, and displays it on the display unit 14.

  FIG. 7 is a screen 41 of the display unit 14 when the search result when the point information is searched by the point name is displayed. When a keyword for name search is entered in the name search keyword input field 42 and the search button 43 is pressed, the point information search unit 20 starts the point information search process shown in FIG. 6 described above, and the points extracted by the point information search process Information is displayed in the search result list 44.

  In addition, when displaying in the search result list 44, the user can recognize the same group attribute by indenting and displaying the names of points other than the information rank 1 or changing the color. Is displayed so that it can be easily judged.

  As described above, in the present embodiment, a plurality of pieces of point information are assigned with group attributes and information ranks, so that a plurality of pieces of point information existing at one point and point information existing at a plurality of points are associated and stored. Therefore, it is possible to easily acquire other spot information related to referring to each spot information and improve convenience.

  In the present embodiment, when the group attribute or information rank is specified by the input unit 11 and the group attribute or information rank is specified, the point information related to the group attribute or information rank stored in the point information is displayed. Since all items are searched and acquired, the point information can be easily associated and the related point information can be easily acquired.

  In the present embodiment, the information rank of the spot information is included as the related information, and when the spot information is displayed on the display unit 14, the spot is based on the currently displayed state and the information rank included in the spot information. Since the display content of the information is determined, the display order of the spot information can be set by the user according to the information rank, and is displayed with the information rank set by the user as shown in FIG. A screen configuration can be adopted.

  1 and 8 are diagrams showing a second embodiment of the point information providing apparatus according to the present invention. In the present embodiment, the point information registration unit 19 divides the first point information describing the general contents into the second point information describing the first point information partially and in detail. Are created, and are associated with each other as the same group attribute and registered in the main memory 17. The point information of the building XX describing the general contents as the first point information is created, The point information of the parking lot in which XX building is partially described in more detail as the point information of 2 is created.

  FIG. 8 is a diagram for schematically explaining a method of using the point information to guide from the XX building to the parking lot as the destination. For those who do not know the information at all about the destination, By creating information and providing this point information, it is possible to easily guide to the destination.

  In FIG. 8, in the present embodiment, since the building 51 and the parking lot 52 are already registered in the main memory 17 as the point information, an appropriate search for extracting the target point information by the input unit 11 is performed. When the condition is input, the XX building 51 and the parking lot 52 are displayed on the display unit 14 as map information and point information.

  Although it is possible to go to the target parking lot using this, the user may get lost because the user does not know the situation near the destination at all. Therefore, the XX building 51 and the parking lot 52 are registered as the same group attribute, and the outline of the route guidance to the parking lot is registered in the XX building 51 as image information.

  Here, it is assumed that the XX building 51 is a famous facility, and even a person who does not know the road can easily reach the XX building 51. Of course, if the XX building 51 is not a famous facility, it can be implemented in the same manner by creating route guidance information from the famous facility to the XX building 51. Therefore, the user who has arrived at the XX building 51 may display the point information regarding the XX building 51 on the display unit 14.

  When the point information related to the building 51 is displayed, the directions 53 to 57 from the building 51 to the parking lot 52 are combined with the map information, and the user can know the directions 53 to 57 to the parking lot. By driving based on this, the user can easily reach the destination parking lot 52. Here, guidance may be performed by matching the vehicle position with the point information screen 58 related to the XX building 51.

  On the other hand, when the parking lot 52 is reached, it is necessary to find out where the space for parking the car is. In the conventional point information providing system, the point information of the corresponding parking lot has to be searched from all the point information, but in this embodiment, the same group attribute is registered from the point information of XX building 51. Since the existing parking lot 52 can be referred to, detailed point information regarding the parking lot 52 can be displayed on the display unit 14 from the point information screen 58 regarding the XX building 51. As a result, no. It is easy to see that parking at 14 is sufficient.

  As described above, in the present embodiment, when it is difficult to store all information in the spot information, the first spot information describing the general contents and a part of the first spot information are more detailed. If the second point information describing the contents is stored in association with each other, a lot of information describing more detailed contents can be stored as the point information.

  1, 9, and 10 are diagrams showing a third embodiment of the point information providing apparatus according to the present invention.

  In the present embodiment, the point information registration unit 19 adds information regarding the position of the corresponding point and information regarding the direction to be displayed to the point information.

  The main controller 16 calculates the distance from the current position information acquired from the current position calculation unit 12 to the display target and calculates the azimuth from the current position to the display target. The point information content display unit 21 Is transmitted from the main controller 16 and the display content of the point information to be displayed is determined using the distance information or the direction information.

  The point information content display unit 21 determines the display content of the point information that is the display target based on the distance from the display target and the importance stored in the point information. In the present embodiment, the current position calculation unit 12 and the main controller 16 also constitute point information processing means.

  Next, the point information content display process in which the display content is changed according to the passing direction based on the flowchart of FIG.

  When displaying the vehicle position and the spot information on the display unit 14, the spot information content display process is started (step S31). In this point information content display processing, first, the main controller 16 acquires the current position and the current direction from the current position calculation unit 12 (step S32).

  Next, the contents are compared for the number of pieces of location information registered by the user (step S33). In this comparison, first, the registration direction of the point information is compared with the current direction (step S34). Here, the registration direction of the point information does not necessarily have to be set, and if it is not set, it may be determined that it is a display target for all directions.

  Next, as a result of the comparison of directions, it is determined whether or not the display target (step S35). If it is determined in step S35 that it is not a display target, it is compared with the next point information. If it is determined in step S35 that it is a display target, the main controller 16 calculates a relative distance from the position of the corresponding point information and the current position (step S36).

  Next, the information rank to be displayed on the screen of the current display unit 14 is determined from the relative distance calculated in step S36, and the point information registered in the information rank to be displayed with the same group attribute is displayed (step S37). Next, the above process is repeated for the number of registered spot information (step S38). When all the comparisons are completed, the spot information content display process is terminated (step S39).

  FIG. 10 is a diagram showing a display screen of the actual display unit 14 and shows an example in which the display contents are changed depending on the passing direction. FIG. 6A shows the screen 61 of the display unit 14 when it is determined that the registered point information 63 is not displayed from the current position 62 and the orientation, and FIG. 5B shows the current position 65 and the orientation. It is the screen 64 of the display part 14 when it is judged that the point information 66 registered from is displayed.

  Here, the reason why the display contents are changed depending on the passing direction will be described. Depending on the point information, it can be divided into useful information and information that is not so depending on the direction of entry, which is effective when displaying such point information.

  For example, if you enter from the north, you cannot see it because there is a tall building near the intersection, but you can see it when you enter from the south.

  Therefore, on the screen 61 when it is determined not to be displayed, the point information determined to be a display target such as not displaying the corresponding point information, displaying but changing from the normal display, displaying but not displaying detailed information, etc. And show it to the user. Further, on the screen 64 when it is determined to be displayed, it is preferable to display the corresponding point information as usual, and display the detailed information 67 of the point information 66 if necessary.

  As described above, according to the present embodiment, the current position and the point information are compared to determine whether or not the display target, and the display target point information and the non-display target point information are displayed separately. Therefore, it is possible to determine whether or not to display arbitrary point information from the stored direction, and it is possible to emphasize important information and provide it to the user.

  Moreover, since the user can set the content for providing the spot information, the spot information that is easier to understand can be provided.

  1 and 11 to 13 are diagrams showing a fourth embodiment of the point information providing apparatus according to the present invention.

  In the present embodiment, the spot information content display unit 21 assigns and stores time information to the spot information, and compares the current time with the time information given to the spot information to display the spot information as a display target. It is a judgment to do. That is, the spot information can be registered as a schedule, and the spot information is provided to the user according to the registered schedule. The time information is timed by time measuring means (not shown) provided in the main controller 16.

  Next, processing for registering point information in the schedule will be described based on the flowchart of FIG.

  In FIG. 11, first, when the schedule registration button of the input unit 11 is operated, a schedule registration process is started (step S41), and the point information related to an arbitrary point is registered and information related to the point information is input from the input unit 11. (Step S42). Here, date, day of the week, time, etc. are registered as information related to the schedule. However, it is not always necessary to input information related to the schedule, and if it is not input, it may be determined that schedule registration is not necessary.

  Next, information on the schedule is referred to from the information on the spot information input in step S42, and it is determined whether there is schedule information (step S43). If there is no schedule information in step S43, the point information is registered and the process is terminated (step S45), and if there is schedule information in step S43, it is registered in the schedule list in the main memory 17 (step S44) and the process is performed. The process ends (step S45).

  Next, display processing for displaying the corresponding spot information on the screen of the display unit 14 will be described based on the flowchart of FIG.

  In FIG. 12, the display processing is started when some point information is registered in the schedule (step S51). In this display process, the current time is first acquired (step S52), and then the schedule list is searched (step S53).

  Next, it is checked whether there is point information to be displayed from the schedule list by comparison with the current time (step S54). If the corresponding point information does not exist in step S54, the display process is terminated (step S56). If the corresponding point information exists, the corresponding point information is displayed on the screen of the display unit 14 (step S55). Then, the process ends (step S56).

  FIG. 13 is a diagram showing a display screen of the display unit 14 displayed by the display process. In FIG. 13, for example, a restaurant 72 is displayed as point information on a screen 71 displaying an arbitrary place at 13:00. On the other hand, a bar 74 is displayed as point information on the screen 73 displaying the same place at 20:00.

  That is, since information from 10:00 to 17:00 is registered as the schedule information in the restaurant 72, it is compared with the current time when displayed, and the restaurant 72 is displayed on the screen 71 displayed at 13:00. However, the restaurant 72 is not displayed on the screen 73 displayed at 20:00.

  In addition, since information from 19:00 to 24:00 is registered as schedule information in the bar 74, the bar 74 is displayed on the screen 71 displayed at 13:00 in comparison with the current time of display. Is not displayed, but a bar 74 is displayed on the screen 73 displayed at 20:00.

  As described above, in the present embodiment, the time information is added to the point information and stored in the main memory 17, and the current time is compared with the time information given to the point information, so that the point information is displayed. Therefore, it is possible to easily obtain only necessary spot information from the same spot information according to time.

  As described above, the spot information providing apparatus according to the present invention can store a plurality of spot information in association with each other, easily acquire other spot information related when referring to each spot information, and is convenient. Point information providing apparatus that can be applied to a navigation device and the like, stores specific point information in association with each other, and can display a plurality of pieces of point information in an easy-to-understand manner Useful as such.
