JP 2004-2011149 A

  By the way, the navigation system has a function of performing route guidance to a destination set and operated by the user, and the user determines a desired facility from a number of facilities that can be set as the destination. Set as the destination. For this reason, if information on a frequently used facility as a destination is provided to the user, the user can easily perform a setting operation.

  However, the configuration that provides information according to the search frequency as in the navigation system described in Patent Document 1 may not be suitable for providing information on facilities that are frequently used as destinations. In other words, in general, search operations are often concentrated on facilities introduced by media such as magazines and facilities that can be easily searched, and the tendency of facilities with high search frequency is This is because the tendency of the facility as the destination does not match.

  The present invention has been made in view of these problems, and an object thereof is to provide information on a frequently used facility as a destination.

  The navigation system according to claim 1, wherein the counting means counts the number of times the destination is set by the setting means for setting the destination according to an operation from the user for each facility. To do. And an information provision means provides a user with the information of the facility with many setting counts totaled by the totalization means.

The facility here is a place that can be set as a destination when guiding a route, and includes, for example, specific places on a map such as buildings, parks, and intersections.
According to the navigation system having such a configuration, the actual result set as the destination is evaluated by the set number of times, and the information according to the evaluation result is given to the user as information on the frequently used facility as the destination. Can be provided.

  By the way, as such a navigation system, for example, it may be configured to provide only information on a facility with a high frequency as a destination, but the configuration according to claim 2 is preferable.

  That is, in the navigation system according to claim 2, the information providing means displays the facility candidates that can be set as the destination by the setting means in a state in which the facilities that are frequently set can be identified. The information is provided to the user. Then, the setting means sets the destination according to the selection operation from the candidates displayed by the information providing means.

  According to the navigation system having such a configuration, when setting a destination, the user can identify information on a frequently used facility as a destination from among facility candidates that can be set as the destination. . As a result, it is possible to select a facility considering the set frequency.

  Here, as the information on the facility having a large number of setting times provided by the information providing unit, specifically, for example, the number of setting tabulated by the tabulating unit is equal to or more than a threshold as in the navigation system of claim 3. It can be considered as facility information. In this way, it is possible to determine a facility with a high frequency set as a destination based on an objective standard. The threshold value may be set in advance or may be settable by the user.

  On the other hand, in the navigation system according to claim 4, the information providing means provides information on a fixed number of facilities having a large number of settings among the facilities whose number of times is set by the counting means as information on facilities having a large number of settings. To do.

According to the navigation system having such a configuration, it is possible to prevent an excessive increase in information provided as a facility with a high setting frequency.
That is, for example, when providing information on a facility whose set number of times is equal to or greater than a threshold as described in claim 3, information provided as a facility having a large number of set times may continue to increase as the usage period becomes longer. If too many facilities are provided in this way, the effect will be lost. On the other hand, according to the structure which provides the information of a fixed number of facilities as described in claim 4, it is possible to always provide a fixed number of facility information regardless of the period of use.

  By the way, as set forth in claim 5, the setting means and the information providing means constituting the navigation system can be used by being mounted on a vehicle, and the counting means is a management capable of communicating with a plurality of vehicles. It can be provided and used in the apparatus.

  According to the navigation system having such a configuration, it is possible to share information on a frequently used facility as a destination among a plurality of users. For this reason, the user can know information on popular facilities based on the set frequency.

Embodiments to which the present invention is applied will be described below with reference to the drawings.
[1. overall structure]
FIG. 1 is a block diagram showing a schematic configuration of the navigation system 1 of the present embodiment.

  As shown in the figure, the navigation system 1 includes a navigation device 10 that is used in a state where it is mounted on a vehicle (automobile), and a facility information management server 20 provided in a management center outside the vehicle. . The facility information management server 20 centrally manages information from the navigation device 10 mounted on a plurality of vehicles.

The navigation device 10 includes a display unit 11, a SW input unit 12, a GPS receiving unit 13, a map data storage unit 14, a communication unit 15, a control unit 16, and the like.
The display unit 11 is a color display device such as a liquid crystal display, an organic EL display, or a CRT, and any of them may be used.

  The SW input unit 12 is for inputting various commands from a user (for example, a vehicle driver or a passenger). In the navigation device 10 of the present embodiment, the SW input unit 12 is configured integrally with the display screen of the display unit 11. And a mechanical key switch provided around the display unit 11. The touch panel and the display unit 11 are laminated and integrated. There are various types of touch panels such as a pressure-sensitive method, an electromagnetic induction method, a capacitance method, or a combination of these methods. It may be used.

  The GPS receiving unit 13 receives a transmission radio wave from a GPS (Global Positioning System) artificial satellite via a GPS antenna (not shown) and detects the current position (latitude, longitude, etc.) of the vehicle. In the navigation device 10, the current position of the vehicle detected by the GPS antenna is corrected based on the traveling speed of the vehicle detected by a vehicle speed sensor (not shown) provided in the vehicle.

  The map data storage unit 14 is configured by a hard disk device (HDD), and stores map data (road data, terrain data, facility position data, etc.). The map data storage unit 14 is not limited to a hard disk device, and may be configured to read map data from a portable storage medium such as a magnetic disk, a magneto-optical disk, or a semiconductor memory. .

  The communication unit 15 is for performing wireless data communication with the facility information management server 20. Specifically, the communication unit 15 performs data communication with the facility information management server 20 on the Internet via a public wireless network that can be connected to the Internet. As such data communication, G-BOOK (registered trademark) or the like is known.

  The control unit 16 is mainly configured by a microcomputer including a CPU, a ROM, a RAM, an I / O, a bus line connecting these components, and executes various processes. For example, the current position of the vehicle is calculated based on the detection signal from the GPS receiving unit 13, and a map around the current position is read from the map data stored in the map data storage unit 14 to represent the current position of the vehicle. A current position display process to be displayed on the display unit 11 together with the vehicle position mark, a route guidance process for searching for and guiding an optimum route from the current position of the host vehicle to the facility set as the destination, and the like are executed. The ROM stores a user name uniquely assigned to each navigation device 10, and further stores a program for executing a facility search process (FIG. 3) described later.

On the other hand, the facility information management server 20 includes a communication unit 21, a control unit 22, a storage unit 23, and the like.
The communication unit 21 performs wireless data communication with a plurality of navigation devices 10.

  The control unit 22 is mainly configured by a microcomputer including a CPU, a ROM, a RAM, and the like, and comprehensively controls each unit constituting the facility information management server 20. The ROM stores a program for executing an information management process (FIG. 4) described later.

  The storage unit 23 is a non-volatile storage medium capable of rewriting stored information. For example, a hard disk device is used. The storage unit 23 stores a facility information database (not shown) and a destination setting history database (FIG. 2).

  The facility information database is a database that manages information on all facilities that can be set as destinations when the navigation apparatus 10 executes the route guidance process described above. Specifically, as information about each facility, the facility genre (for example, industry such as hot springs, convenience stores, restaurants, etc.), facility name, facility address, telephone number, other facility information, and position coordinates (hereinafter, these information are summarized) "Facility information") is stored.

  In addition, the destination setting history database is a database that manages information on how many navigation devices 10 are set as destinations for each facility registered in the facility information database.

  That is, although specific processing will be described later, when a destination is set in the navigation device 10, the information is transmitted to the facility information management server 20. Then, the facility information management server 20 extracts facility information about the facility set as the destination from the facility information database, and associates the facility information with the user name of the navigation device 10 set as the destination. Register in the land setting history database.

  Specifically, if information that matches both the facility information and the user name is not registered in the destination setting history database, the facility information and the user name are newly registered. At this time, the priority (value indicating the total number of times set as the destination) is registered as “1” in association with the facility information and the user name. On the other hand, when information that matches both the facility information and the user name is already registered in the destination setting history database, the priority of the information already stored is updated (1 is added to the priority).

  As a result of such processing, information including priority, user name, and facility information (hereinafter referred to as “destination setting history”) is stored in the destination database as shown in FIG. Each time a destination setting operation is performed in the navigation device 10, the destination setting history is added or the priority of the registered destination setting history is updated.

[2. Processing performed in the navigation system]
Next, facility search processing performed by the control unit 16 of the navigation device 10 in the navigation system 1 will be described with reference to the flowchart of FIG. The facility search process is started when a facility search operation for searching for a facility is performed by the user at the SW input unit 12.

  When the facility search process is started, first, in S101, the process waits until an input operation of a search condition that is a condition of the facility to be searched is performed by the user at the SW input unit 12. When the search condition input operation is performed, the process proceeds to S102. The search conditions include the genre of the facility and the facility address.

In S102, the search condition input in S101 and the user name stored in the ROM are transmitted to the facility information management server 20 via the communication unit 15.
Subsequently, in S103, display data transmitted from the facility information management server 20 as a response to the search condition and user name transmitted in S102 is received via the communication unit 15. Here, the display data is for displaying the facility name on the display screen of the display unit 11 (see “Destination Setting Screen 1” and “Destination Setting Screen 2” in FIG. 5), and S101. The facility name of the facility corresponding to the search condition input in (1) and the display mode information of the facility name (information representing the display rule such as the display order of the facility name and the star name attached to the facility name) are included.

  Subsequently, in S104, the facility name is displayed on the display unit 11 based on the display data received in S103. Specifically, the facility name included in the display data is displayed on the display unit 11 in accordance with the display mode information included in the display data.

Subsequently, in S105, it is determined whether or not a destination selection operation for selecting one of the facility names displayed in S104 as a destination has been performed by the user at the SW input unit 12.
If it is determined in S105 that the destination selection operation has not been performed, the process proceeds to S106, and other operations (operations other than the destination selection operation are performed. For example, a facility is searched using another search condition. It is determined whether or not a re-search operation for searching or a search end operation for ending the facility search has been performed by the user at the SW input unit 12.

If it is determined in S106 that no other operation is performed, the process returns to S105.
On the other hand, when it determines with other operation having been performed by S106, this facility search process is complete | finished. In this case, necessary processing is executed according to the contents of other operations.

If it is determined in S105 that the destination selection operation has been performed, the process proceeds to S107, and the facility selected in S105 is set as the destination.
Subsequently, in S108, the facility name of the facility set as the destination in S107 and the user name stored in the ROM are transmitted to the facility information management server 20 via the communication unit 15.

  Subsequently, in S109, an optimum route from the current position to the destination set in S107 is determined based on the map data stored in the map data storage unit 14, the position of the vehicle detected by the GPS receiving unit 13, and the like. The route guidance process for searching and guiding is started, and the facility search process is terminated.

Next, information management processing performed by the control unit 22 of the facility information management server 20 in the navigation system 1 will be described with reference to the flowchart of FIG.
When the information management process is started, first, in S201, it is determined whether or not the search condition and the user name transmitted from the navigation device 10 are received via the communication unit 21. The search condition and the user name are transmitted in S102 in the facility search process (FIG. 3) described above.

  If it is determined in S201 that the search condition and the user name have been received, the process proceeds to S202. In S202, an extraction process is performed to extract the facility name included in the facility information corresponding to the search condition received in S201 from the facility information database in the storage unit 23. Specifically, if the information included in the facility information includes information that matches the search condition received in S201, the facility name of the facility is extracted.

  Subsequently, in S203, it is determined whether or not a facility having a high frequency set as a destination (hereinafter referred to as “high frequency facility”) exists among the facilities having the facility name extracted in S202. Specifically, for each facility with the facility name extracted in S202, the destination setting history having the same facility name in the destination setting history database and the priority is equal to or higher than a threshold (2 in this embodiment). It is determined whether or not exists. Then, a facility having such a destination setting history is determined as a high frequency facility, and a facility having no such destination setting history is determined as not a high frequency facility.

  In S203, if it is determined that there is no high-frequency facility among the facilities with the facility name extracted in S202, the process proceeds to S204, and the extracted facility name is displayed on the display unit 11 of the navigation apparatus 10 in Japanese. Create display data to display the list in order. Specifically, the display data including the facility name extracted in S202 and the display mode information for displaying the facility name in alphabetical order is created. Then, the process proceeds to S206.

  On the other hand, if it is determined in S203 that a high-frequency facility exists in the facilities with the facility name extracted in S202, the process proceeds to S205, and the extracted facility name is displayed on the display unit 11 of the navigation device 10 (A Display data to be displayed in a list according to the rules (1) to (C).

  (A) Of the facilities with the facility name extracted in S202, the facilities are grouped into a high frequency facility and a non-high frequency facility, and the facility name of the high frequency facility group is set to be more than the facility name of the group of the non-high frequency facility group. Display at the top.

(B) Within each group, the facility names are displayed in alphabetical order.
(C) An asterisk is attached to the facility name of the group of high-frequency facilities.
Specifically, display data including the facility name extracted in S202 and the display mode information for displaying the facility name according to the rules (A) to (C) is created. For this reason, on the display screen based on this display data, as shown in “Destination setting screen 2” in FIG. 5, a high-frequency facility (□ ○ hot spring in FIG. 5) is selected from the facility names corresponding to the search conditions. Can be easily identified. Then, the process proceeds to S206.

  In S206, a transmission process for transmitting the display data created in S204 or S205 to the navigation device 10 corresponding to the user name received in S201 via the communication unit 21 is performed. That is, display data for displaying a list of facility names corresponding to the search condition is returned to the navigation apparatus 10 that has transmitted the search condition.

  If it is determined in S201 that the search condition and the user name are not received, the process proceeds to S207, and whether the facility name and the user name transmitted from the navigation device 10 are received via the communication unit 21 or not. Determine whether. The facility name and the user name are transmitted in S108 in the above-described facility search process (FIG. 3).

If it is determined in S207 that the facility name and the user name have not been received, the process returns to S201.
On the other hand, if it is determined in S207 that the facility name and the user name have been received, the process proceeds to S208, and the number of times the destination is set in the navigation device 10 is determined for each facility and for each navigation device 10 (for each user name). Performs priority aggregation processing for aggregation. Specifically, if the destination setting history that matches both the facility name and the user name received in S207 is not registered in the destination setting history database, the facility information corresponding to the facility name received in S207, The user name received in S207 and the priority “1” are newly added to the destination setting history database as the destination setting history. On the other hand, if the destination setting history having the same facility name and user name received in S207 is already registered in the destination setting history database, 1 is set as the priority of the destination setting history already stored. to add. By performing such processing, the number of times the destination is set in the navigation device 10 is totaled for each facility and each user name. Then, the process returns to S201.

[3. Specific example of processing]
Next, a specific example of processing realized by the navigation system 1 configured as described above will be described with reference to FIG.

[3.1. When there are no high-frequency facilities among the facilities corresponding to the search conditions]
When the user of the navigation device 10 inputs “□□ prefecture” and “hot spring” as search conditions in order to obtain information on “□□ prefecture hot springs” (S101: YES), the navigation device 10 inputs the information. The retrieved search conditions are transmitted to the facility information management server 20 (S102).

  When the facility information management server 20 receives the search condition from the navigation device 10 (S201: YES), the facility name corresponding to the search condition (specifically, the facility address is □□ prefecture and the facility genre is a hot spring facility). The facility name included in the information) is extracted from the facility information database (S202). Here, since there are no high-frequency facilities among the facilities corresponding to the hot springs in □□ prefecture (S203: NO), display data for displaying the extracted facility names in a list in the order of the Japanese syllabary is created (S204). ) And transmitted to the navigation device 10 (S206).

  Upon receiving the display data from the facility information management server 20 (S103), the navigation device 10 displays the facility name based on the display data as shown in “Destination setting screen 1” in FIG. Provincial hot springs are provided to the user (S104). When the user selects “□ ○ hot spring” as the destination from the displayed facility names (S105: YES), the navigation device 10 sets “□ ○ hot spring” as the destination by the user. Is sent to the facility information management server 20 (S108).

  Upon receiving the setting result from the navigation device 10 (S207: YES), the facility information management server 20 adds “□ ○ hot spring” and the destination setting history representing the source navigation device 10 to the destination setting history database ( Alternatively, the priority of the existing destination setting history is updated) (S208).

[3.2. When there is a high-frequency facility among the facilities corresponding to the search conditions]
When the user of the navigation device 10 inputs “□□ prefecture” and “hot spring” as search conditions in order to obtain information on “□□ prefecture hot springs” (S101: YES), the navigation device 10 inputs the information. The retrieved search conditions are transmitted to the facility information management server 20 (S102).

  When the facility information management server 20 receives the search condition from the navigation device 10 (S201: YES), the facility name corresponding to the search condition (specifically, the facility address is □□ prefecture and the facility genre is a hot spring facility). The facility name included in the information) is extracted from the facility information database (S202). Here, since there are high-frequency facilities among the facilities corresponding to the hot springs in □□ prefecture (S203: YES), display data for displaying the extracted facility names in a state where the high-frequency facilities can be identified Is created (S205) and transmitted to the navigation device 10 (S206).

  Upon receiving the display data from the facility information management server 20 (S103), the navigation device 10 displays the facility name based on the display data as shown in “Destination setting screen 2” in FIG. Provincial hot springs are provided to the user (S104). At this time, since the high-frequency facilities are displayed in a higher order and are marked with a star, the user can easily grasp the high-frequency facilities (in other words, popular facilities).

  When the user selects a destination facility from the displayed facility names (S105: YES), the navigation device 10 determines that the above-mentioned “the facility corresponding to the search condition includes a high-frequency facility. As in the case of “No”, the setting result that the facility selected by the user is set as the destination is transmitted to the facility information management server 20 (S108). Then, when the facility information management server 20 receives the setting result from the navigation device 10 (S207: YES), the destination setting that represents the facility set as the destination in the destination setting history database and the navigation device 10 of the transmission source. A history is added (or the priority of the existing destination setting history is updated) (S208).

[4. Effects of the embodiment]
As described above, according to the navigation system 1 of the present embodiment, since the performance actually set as the destination is evaluated based on the priority (number of times set), the credibility as the information on the popular facility is obtained. High information can be provided to the user. Specifically, when the facility searched for in the navigation device 10 is displayed, the high-frequency facility is displayed so as to be identifiable. Therefore, the user sets the destination in consideration of the popularity of the facility. be able to. In particular, since a facility whose priority is equal to or higher than a threshold is a high-frequency facility, a popular facility can be determined based on an objective standard.

  In the navigation system 1, the facility information management server 20 collectively manages information from a plurality of navigation devices 10 (information indicating which facility is set as a destination in which navigation device 10). . For this reason, information on popular facilities can be shared among users of a plurality of navigation devices 10.

[5. Correspondence with Claims]
Note that the SW input unit 12 of this embodiment and the processing of S101 and S107 in the facility search process (FIG. 3) correspond to the setting means of the present invention, and in the display unit 11 and the facility search process (FIG. 3). The process of S104 corresponds to the information providing means of the present invention. In addition, the process of S208 in the information management process (FIG. 4) corresponds to the counting means of the present invention.

[6. Other forms]
As mentioned above, although one Embodiment of this invention was described, it cannot be overemphasized that this invention can take a various form.

  Since the navigation system 1 of the above embodiment displays the high-frequency facilities in an identifiable manner, the display order of the facility names of the high-frequency facilities is placed at the top and a star is added. However, the navigation system 1 is not limited to this. Absent. For example, by displaying the color, size, font, etc. of the facility name of the high frequency facility so as to be distinguished from other facility names, the high frequency facility can be displayed in an identifiable manner.

  Moreover, in the navigation system 1 of the said embodiment, although the alphabetical order was illustrated as a display order of a facility name, the order other than this may be sufficient. For example, if the items are displayed in descending order of priority, the user can grasp the degree of popularity of the facility in more detail.

  Furthermore, in the navigation system 1 of the above-described embodiment, the facility names are displayed in the same order (alphabetical order) on all navigation devices 10, but the present invention is not limited to this. For example, the facility names may be displayed in a different display order for each navigation device 10. Specifically, a display order (for example, alphabetical order, alphabetical order, descending order of priority) is set for each user name included in the destination setting history database of the facility information management server 20, When a search condition and a user name are transmitted from each navigation device 10 to the facility information management server 20, the facility information management server creates display data for displaying the facility name in the display order corresponding to the received user name. To do. According to the navigation system having such a configuration, the facility name can be provided in accordance with the preference of the user of each navigation device 10.

  By the way, in the navigation system 1 of the above embodiment, the number of times (priority) set as the destination for each facility is managed separately for each user name, and a plurality of destination setting histories exist for the same facility. obtain. For this reason, in the structure of the said embodiment, even if it is a plant | facility set as the destination in many navigation apparatuses 10, if the frequency | count of setting in each navigation apparatus 10 is small, it is possible that it is not determined as a high frequency facility. Therefore, if the priority for each facility and each user name is equal to or higher than the threshold, it is not determined that the facility is a high-frequency facility, but the priority for each facility (the priority obtained by summing the priorities of different user names) is the threshold. When it is above, it may be determined that the facility is a high-frequency facility. In this way, it is possible to reliably provide information on facilities popular with many users.

  In the navigation system 1 of the above embodiment, the threshold value is a fixed value. However, the threshold value is not limited to this. For example, the user can freely set the threshold value by inputting from the SW input unit 12. You may do it. By doing in this way, the number of information of the high frequency facility made into the destination can be adjusted.

  By the way, in the navigation system 1 of the said embodiment, when displaying the facility name corresponding to the search condition input by the user, information on a popular facility is made available to the user by making it possible to identify a high-frequency facility. However, the present invention is not limited to this. For example, when traveling near a popular facility, the name of the facility is displayed on the screen, so that information can be provided at a timing unrelated to the input of the search condition. is there.

  Moreover, in the navigation system 1 of the said embodiment, since all the facilities whose priority is a threshold value or more are made into high frequency facilities, it is possible that the number of high frequency facilities will increase excessively. Therefore, the maximum number of high frequency facilities may be limited. For example, if the maximum number is 5, and there are 6 or more facilities with a priority equal to or higher than the threshold, the high-frequency facilities are narrowed down to five. At that time, as a condition for narrowing down the high-frequency facilities, for example, a method in which priority is given to a higher priority is preferred. Moreover, it is also possible to adopt a configuration in which a threshold value itself is not provided, and a higher priority is provided within a predetermined maximum number.

  In the navigation system 1 of the above embodiment, the display information including the facility name and the display mode information is created in the facility information management server 20, but the present invention is not limited to this. For example, the facility information management server 20 transmits the facility name and the priority of each facility name instead of transmitting the facility name and the display mode information as display data, and the navigation device 10 determines the facility name based on the received priority. You may make it set display rules, such as a display order.

  Furthermore, in the navigation system 1 of the above embodiment, the user name is transmitted every time information is transmitted from the navigation device 10 to the facility information management server 20, but the present invention is not limited to this. For example, once the user name is transmitted between the time when the communication connection is established between the navigation device 10 and the facility information management server 20 until the connection is disconnected, the navigation device 10 is identified based on the user name. Therefore, the user name transmission process can be omitted.

  Moreover, in the said embodiment, although the navigation system 1 which consists of several navigation apparatus 10 and the facility information management server 20 was illustrated, it is not limited to this, This invention is implement | achieved also by a navigation apparatus single-piece | unit. Can do. Specifically, for example, a configuration corresponding to the storage unit 23 of the facility information management server 20 is provided in the navigation device 10. And the control part 16 of the navigation apparatus 10 performs the process equivalent to a facility search process (FIG. 3) and an information management process (FIG. 4). However, in this case, since information from the other navigation device 10 is not acquired, only the information of the navigation device 10 (own information) is stored in the destination setting history database (FIG. 2). Thus, the user name need not be stored. Also, the transmission / reception processing (S102, S103, S108, S201, S206, S207) in the facility search processing (FIG. 3) and the information management processing (FIG. 4) is unnecessary, and the processing of FIG. 3 and FIG. The process is alternately executed and executed. Even with such a configuration, it is possible to provide a user with information on a facility that has been set as a destination in the past in the navigation device 10.
