  The condition acquisition unit 101 acquires a condition for acquiring evaluation information from the facility evaluation information DB 210 of the server device 200 (also referred to as “evaluation information acquisition condition Te”), and outputs the condition to the evaluation information acquisition unit 108. In this case, the condition acquisition unit 101 acquires the evaluation information acquisition condition Te by receiving, for example, user input information specifying the evaluation information acquisition condition Te from the input device 60. Note that the condition acquisition unit 101 may acquire information on facility search conditions from an external mobile phone or computer via the communication device 38 instead of acquiring facility search conditions based on user input.

  Here, the evaluation information acquisition condition Te is a condition related to evaluation that is emphasized by the user when selecting a facility. For example, when searching for a dining facility, a condition for tastes such as “delicious” and “delicious”, “ Applicable conditions include in-store conditions and services such as “Clean”, “Wide seats”, “Good customer service”. Similarly, for a facility other than a dining facility, a condition related to evaluation that is emphasized by the user when selecting a facility is designated as the evaluation information acquisition condition Te. Note that the evaluation information acquisition condition Te is not limited to a condition in which a predetermined word is specified as in the above-described example, but may be a condition in which an evaluation value obtained by quantifying the evaluation is specified, as will be described later.

  The traffic information acquisition unit 102 acquires traffic information and outputs the traffic information to the estimation unit 106. For example, the traffic information acquisition unit 102 acquires the traffic information received by the communication device 38 from the VICS center or the like.

  The departure point acquisition unit 103 acquires the departure point of the vehicle on which the navigation device 100 is mounted and outputs the departure point to the route search unit 105. The starting point acquisition unit 103 acquires starting point information from, for example, the autonomous positioning device 10 and the GPS receiver 18 that measure the current position of the vehicle on which the navigation device 100 is mounted, as shown in FIG. The starting point acquisition unit 103 may acquire the starting point directly input by the user instead of acquiring the starting point information from the GPS receiver 18 or the like, and the communication device 38 may be connected from an external mobile phone or a computer. The received starting point may be acquired. In this case, the departure point acquisition unit 103 may acquire an arbitrary point as a departure point, not limited to the departure point of the vehicle on which the navigation device 100 is mounted.

  The destination acquisition unit 104 acquires the destination of the vehicle and outputs it to the route search unit 105. For example, the destination acquisition unit 104 detects the user's direct input to the input device 60 and acquires the destination. The destination acquisition unit 104 may acquire the destination received by the communication device 38 from an external mobile phone or computer. Further, the destination acquisition unit 104 may acquire not only the destination of the vehicle but also any point as the destination.

  The route search unit 105 searches for a route from the departure point to the destination based on the departure point input from the departure point acquisition unit 103 and the destination input from the destination acquisition unit 104, and the obtained route Is supplied to the estimation unit 106 and the display unit 40. When the input device 60 detects an input for specifying various route search conditions such as distance priority and charge priority in addition to the destination, the route search unit 105 satisfies the specified route search condition. , Perform route search.

  The estimating unit 106 estimates each estimated arrival point at a plurality of times after the departure time (also referred to as “reference time Ttag”) based on the traffic information acquired from the traffic information acquiring unit 102. In this case, first, the estimation unit 106 is a route searched by the route search unit 105 based on the route information supplied from the route search unit 105, and is also referred to as a route before the vehicle passes (a “travel planned route”). ) Next, the estimation unit 106 determines a plurality of reference times Ttag, and estimates an estimated arrival point on the planned travel route at each determined reference time Ttag based on the traffic information. Then, the estimation unit 106 notifies the facility search unit 107 of the estimated arrival point information. Here, the reference time Ttag is set to, for example, a plurality of times that have equal time intervals from the time zone specified by the user as the time zone from the departure time to the estimated arrival time to the destination or the time zone to stop at the facility. The The departure time may be the time when the current position of the vehicle on which the navigation device 100 is mounted is measured by the autonomous positioning device 10 and the GPS receiver 18, the time directly input by the user, or an external mobile phone Or the time which the communication apparatus 38 received from the computer etc. may be sufficient.

  The facility search unit 107 refers to the map data stored in the data storage unit 36 and refers to facilities around the predicted arrival point at each reference time Ttag notified from the estimation unit 106 (also simply referred to as “corresponding facility”). Search for. In this case, the facility search unit 107 searches for a facility for a range in which a linear distance or a required travel distance from each predicted arrival point is within a predetermined distance (for example, 100 m). Then, the facility search unit 107 transmits information such as identification information (also referred to as “facility ID”) of the corresponding facility to the evaluation information acquisition unit 108. When the facility search condition such as the genre of the facility is designated by the user input, the facility search unit 107 searches for the facility that satisfies the designated condition as the above-mentioned corresponding facility.

  The evaluation information acquisition unit 108 acquires evaluation information (also referred to as “corresponding evaluation information”) of each corresponding facility that satisfies the evaluation information acquisition condition Te from the server device 200 via the communication device 38. In this case, the evaluation information acquisition unit 108 sends an evaluation information acquisition request including the evaluation information acquisition condition Te acquired by the condition acquisition unit 101 and the facility ID of the corresponding facility searched by the facility search unit 107 to the server device 200 via the communication device 38. Send to. In this case, the server device 200 searches the facility evaluation information DB 210 for the corresponding evaluation information for each corresponding facility based on the facility ID and the evaluation information acquisition condition Te included in the received evaluation information acquisition request, and transmits the search result to the communication device. 38. Then, the evaluation information acquisition unit 108 acquires the search result received by the communication device 38 and supplies the corresponding evaluation information for each corresponding facility to the calculation unit 109 and the control unit 110.

  The calculation unit 109 counts the number of evaluation information for each corresponding facility supplied from the evaluation information acquisition unit 108, and averages the number of the corresponding evaluation information for each corresponding facility (also referred to as “evaluation information average number Nv”). Is calculated. Specifically, the calculation unit 109 calculates the average number of evaluation information Nv by dividing the total number of the corresponding evaluation information of all the corresponding facilities by the number of the corresponding facilities. Then, the calculation unit 109 notifies the control unit 110 of the calculated evaluation information average number Nv.

  The control unit 110 compares the number of corresponding evaluation information for each corresponding facility notified from the evaluation information acquisition unit 108 with the average number of evaluation information Nv, and the number of corresponding evaluation information is larger than the average number of evaluation information Nv. Recognize the facility as a display target. And the control part 110 displays the information of the applicable facility recognized as a display target on a map with a driving plan route etc. by controlling the display unit 40. FIG.

[Example of facility evaluation information DB]
FIG. 4 is an example of the data structure of the facility evaluation information DB 210. The facility evaluation information DB 210 shown in FIG. 4 is a database of evaluation information including information on facility IDs, five-step evaluation, and evaluation comments. The server device 200 receives, for example, input information input according to a predetermined form on an introduction page for each facility at a word-of-mouth site from a terminal used by a user of each facility. Generate a record. In the example of FIG. 4, the server apparatus 200 generates each record of the facility evaluation information DB 210 by receiving information input according to an input form including a five-step evaluation and an evaluation comment.

  And when the server apparatus 200 receives the search request | requirement of the evaluation information containing evaluation information acquisition condition Te and the facility ID of an applicable facility from the navigation apparatus 100, it evaluates among the records which match the facility ID of the designated corresponding facility. Records satisfying the information acquisition condition Te are extracted as corresponding evaluation information for each corresponding facility.

  For example, when a condition related to a five-level evaluation (for example, a condition that the five-level evaluation is 3 or more) is specified as the evaluation information acquisition condition Te, the server apparatus 200 extracts the reference by referring to the item of the five-level evaluation Determine the record to be executed. As another example, when a word such as “delicious” is specified as the evaluation information acquisition condition Te, the server device 200 extracts a record having an evaluation comment including the specified word as the corresponding evaluation information. . At this time, preferably, the server device 200 stores synonym information in which synonyms are associated with each other, and a record having an evaluation comment including either the word specified as the evaluation information acquisition condition Te or a synonym of the word, It may be extracted as relevant evaluation information. As a specific example, when “delicious” is specified as the evaluation information acquisition condition Te, the server device 200 refers to the synonym information to set the synonym “delicious” (here, “delicious”). Identify. Then, the server apparatus 200 searches for an evaluation comment using “delicious” and its synonym “delicious” as a search word, and extracts a corresponding record as corresponding evaluation information.

  The facility evaluation information DB 210 is not limited to the data structure shown in FIG. For example, the five-level evaluation may be provided for each of various evaluation items such as the amount of money and taste, or may be an evaluation value having an arbitrary numerical value other than 5 as an upper limit.

[Facility search processing]
(1) Process Flow FIG. 5 is a flowchart showing the procedure of the facility search process executed by the CPU 22 of the navigation device 100 in this embodiment. The CPU 22 executes the flowchart shown in FIG. 5 every time a user input requesting facility search is detected. Note that when the flowchart shown in FIG. 5 is executed, the route search unit 105 searches for a route based on a user input specifying a route search condition such as a destination, and the route to the destination is already set. To do.

  First, the condition acquisition unit 101 of the CPU 22 receives an input specifying the evaluation information acquisition condition Te by the input device 60 (step S101). In addition to the evaluation information acquisition condition Te, the condition acquisition unit 101 may further receive various facility search conditions such as a time zone for stopping the facility and a genre of the facility by the input device 60.

  Next, the estimation unit 106 estimates a plurality of predicted arrival points on the planned travel route based on the route information supplied from the route search unit 105, the traffic information supplied from the traffic information acquisition unit 102, and the like (step S102). For example, in this case, the estimation unit 106 predicts the arrival point on the planned travel route at each reference time Ttag obtained by dividing the time zone from the departure time to the expected arrival time of the destination by a predetermined time width (for example, 15 minutes). Is estimated based on traffic information. Note that the estimation unit 106 sets a plurality of times belonging to the designated time zone as the reference time Ttag when the designation of the time zone to stop at the facility is included in the facility search condition.

  Thereafter, the facility search unit 107 refers to the map data and searches for facilities existing around each estimated arrival point (step S103). The facility search unit 107 searches for a facility that satisfies the specified condition when the genre of the facility is specified as the facility search condition.

  Next, the evaluation information acquisition unit 108 acquires corresponding evaluation information that matches the evaluation information acquisition condition Te of each corresponding facility from the server device 200 (step S104). In this case, the evaluation information acquisition unit 108 transmits an evaluation information acquisition request specifying the facility ID and the evaluation information acquisition condition Te of the corresponding facility searched by the facility search unit 107 to the server device 200, and the server device 200 responds as a response. The corresponding evaluation information of each corresponding facility received by the communication device 38 is acquired.

  Then, the calculation unit 109 calculates an evaluation information average number Nv, which is an average value of the corresponding evaluation information for each corresponding facility, based on the number of the corresponding evaluation information for each corresponding facility acquired by the evaluation information acquiring unit 108. (Step S105). Then, the control unit 110 controls the display unit 40 so that the location of the corresponding facility having the number of pieces of the evaluation information larger than the average evaluation information number Nv calculated in step S105 is displayed on the map together with the route to the destination. (Step S106).

  In step S106, the control unit 110 displays the corresponding facility having the number of the corresponding evaluation information items larger than the average evaluation information number Nv. In addition, the control unit 110 displays the corresponding evaluation information equal to the average evaluation information number Nv. The corresponding facility that is the number of cases may be further displayed.

(2) Specific Example Next, a specific example of the facility search process shown in FIG. 5 will be described with reference to FIGS.

  FIG. 6A shows the planned travel route to the destination and the predicted arrival points (points A to D) estimated by the estimation unit 106. In this example, it is assumed that the time zone from 11:30 to 12:15 is designated as the time zone for visiting the facility, and “delicious” is designated as the evaluation information acquisition condition Te.

  In this case, the estimation unit 106 sets each time of 15 minute intervals in the designated time zone as the reference time Ttag, and estimates the predicted arrival points A to D on the planned travel route corresponding to each reference time Ttag. ing.

  FIG. 6B shows the positions of the corresponding facilities a to f searched by the surrounding search of the predicted arrival points A to D. In the example of FIG. 6B, the facility search unit 107 searches the facility a around the point A, the facility b around the point B, the facility c around the point C, and the facilities d to f around the point D as corresponding facilities. ing. In this case, the evaluation information acquisition unit 108 includes the facility ID of each of the facilities a to f and “delicious” that is the evaluation information acquisition condition Te in the evaluation information search request, and transmits it to the server device 200 by the communication device 38. To do.

  FIG. 6C is a table showing search results based on the evaluation information search request. The table shown in FIG. 6C shows the number of searches in the facility evaluation information DB 210 of “delicious” and its synonym “delicious” that are the evaluation information acquisition condition Te for each corresponding facility a to f, and the total number of searches. Each is shown. Then, the server device 200 extracts the corresponding evaluation information that matches the evaluation information acquisition condition Te for each corresponding facility a to f from the facility evaluation information DB 210 and transmits it to the navigation device 100. In this case, the calculation unit 109 calculates that the sum of the corresponding evaluation information of the corresponding facilities a to f is “20” (= 1 + 7 + 1 + 5 + 3 + 3) and the number of the corresponding facilities is “6”. Is calculated as “20/6 (about 3.3)”. Therefore, in this case, the control unit 110 recognizes the relevant facilities b and d having more relevant evaluation information than the average number of evaluation information Nv as display targets.

  FIG. 7A is a display example of the facility search result displayed on the display 44. In the example of FIG. 7 (A), the navigation device 100 includes a planned travel route 72, a departure point mark 73 indicating a departure point, a destination mark 74 indicating a destination, and facilities corresponding to the corresponding facilities b and d. The marks 75b and 75d are displayed on a map (not shown).

  FIG. 7B is a display example when the facility mark 75d corresponding to the facility d is selected by user input. When the facility mark 75d is selected from the state of FIG. 7A, the control unit 110 refers to the facility data of the facility corresponding to the selected facility mark 75d from the data storage unit 36, and displays detailed information on the facility. Display. In the example of FIG. 7B, the control unit 110 is in a balloon 76 indicating the store name, business hours, and telephone number of the facility “Italian restaurant XX” corresponding to the selected facility mark 75d, and pointing to the facility mark 75d. Is displayed. Further, in the example of FIG. 7B, the control unit 110, based on the corresponding evaluation information of the corresponding facility d acquired from the server device 200, the number of corresponding evaluation information of the corresponding facility d (5 cases) and the corresponding evaluation The average value (4.1) of the five-step evaluation included in the information is displayed in the balloon 76. The information in the facility marks 75b, d and the balloon 76 is an example of “facility information” in the present invention.

Select the facilities to be displayed on the map based on the number of information. Thereby, the navigation apparatus 100 can preferentially present the information of the facility to which many evaluations that are emphasized by the user are posted.

[Modification]
Hereinafter, each modification of the embodiment will be described. These modifications may be applied in combination to the above-described embodiments.

(Modification 1)
In step S106 in FIG. 5, the control unit 110 determines the corresponding facility to be displayed by comparing the average number of evaluation information Nv with the number of corresponding evaluation information of each corresponding facility. Instead, the control unit 110 may determine the corresponding facility to be displayed by comparing the value set based on the average number of evaluation information Nv with the number of the corresponding evaluation information of each corresponding facility. .

  For example, after calculating the average number of evaluation information Nv, the control unit 110 compares the value obtained by rounding up the decimal point of the average number of evaluation information Nv with the number of corresponding facilities at each search reference point Ptag. For example, in the example of FIG. 6, the control unit 110 compares the calculated evaluation information average number Nv with a value “4” rounded up below the decimal point and the number of corresponding facilities at each search reference point Ptag, The corresponding facility (that is, the facilities b and d) that is the number of the corresponding evaluation information more than (that is, 5 or more) is determined as the facility to be displayed.

  According to this modification, the control unit 110 can more accurately extract and display a facility that has posted a large number of evaluations of a criterion that is important to the user. As another example, the control unit 110 replaces the average number of evaluation information Nv with the number of pieces of corresponding evaluation information larger than the median value of the number of pieces of relevant evaluation information for each relevant facility (three in the example of FIG. 6). The relevant facility may be determined as a display target facility.

(Modification 2)
The control unit 110 may weight the corresponding evaluation information of each corresponding facility.

  For example, the control unit 110 weights the corresponding evaluation information of each corresponding facility based on attributes such as the age and preference of the evaluator who is the poster of the corresponding evaluation information. In this case, each record of the facility evaluation information DB 210 is further associated with information such as the evaluator's age and preference, and the control unit 110 includes the evaluator's attributes included in the evaluation information received from the server device 200. The weighting value is determined by comparing with an attribute such as the age of the user of the navigation device 100 stored in advance in the data storage unit 36 or the like. The attribute to be compared may be an attribute designated by user input or a preset attribute. Then, the control unit 110 determines the corresponding facility to be displayed based on a value (also referred to as “point number”) obtained by tabulating the determined weight value for each corresponding facility.

  FIG. 8 is a table showing the number of points of each facility a to f when the evaluation information is weighted based on the age in the specific examples of FIGS. 6 and 7. In FIG. 8, “corresponding evaluation number” indicating the number of corresponding evaluation information for each corresponding facility, “number of evaluations according to the same age” indicating the number of corresponding evaluation information by the evaluator of the same age as the user of the navigation device 100, “ The number of points is related.

  In the example of FIG. 8, the evaluation information acquisition unit 108 sets the weight of evaluation information by the evaluator of the same age as the user of the navigation device 100 to “2”, sets the weight of other evaluation information to “1”, and sets the number of points. Calculated. For example, in the case of the facility b, since there are two pieces of relevant evaluation information by the evaluator of the same age and five pieces of other relevant evaluation information, the number of points of the facility b is “9” (= 2 × 2 + 5 ).

  In this case, the calculation unit 109 calculates an average value of the number of points of each facility a to f (also referred to as “average number of points”). In the example of FIG. 8, the calculation unit 109 divides the total number of points “29” of the facilities a to f by the number of corresponding facilities “6”, thereby obtaining the above average point number “29/6 (about 4.8)”. Is calculated. Then, the control unit 110 determines the facilities b, d, and e having a larger number of points than the average number of points “29/6” as the display target facility.

  FIG. 9 is a flowchart of the facility search process according to this modification. Steps S201 to S204 are the same processing as steps S101 to S104 in FIG.

  After acquiring the corresponding evaluation information of each corresponding facility in step S204, the evaluation information acquisition unit 108 weights each corresponding evaluation information based on a predetermined attribute such as the age of the evaluator and calculates the number of points for each corresponding facility ( Step S205). Then, the calculation unit 109 calculates the average number of points of the corresponding facility based on the calculated number of points for each corresponding facility (step S206). Then, the control unit 110 controls the display unit 40 to display information on the relevant facility that has a higher number of points than the average number of points together with the planned travel route (step S207).

  As described above, in this modification, the navigation apparatus 100 sets the weight of the evaluation information of the evaluator that matches the user's attribute to a high value, so that the facility desired by the user can be selected more accurately and displayed on the map. Can be made.

(Modification 3)
In the example of FIG. 6, the facility search unit 107 searches for facilities around the predicted arrival point at each reference time Ttag extracted every predetermined time interval (15 minutes). However, the facility search method to which the present invention is applicable is not limited to this.

  For example, the facility search unit 107 may search for peripheral facilities based on points on the planned travel route with equal distances. The above-mentioned distance may be a straight distance or a travel distance necessary for the movement of the vehicle. In another example, the facility search unit 107 may perform a facility search for an area within a predetermined distance from the planned travel route. In these examples, it is not necessary to perform the estimated arrival point estimation process by the estimation unit 106.
