That is, since the information of the personal parking points Pi registered by a large number of users is uploaded to the data management server, the data storage unit 36 shares the information of the personal parking points Pi registered by other users with the shared parking points. Store as Pu information.

  When the personal parking point Pi, the shared parking point Pu, and the existing parking point Pa overlap each other, the system controller 20 stores only one of the parking points P in the data storage unit 36 based on a predetermined priority order. You may let them.

[First embodiment]
(Basic explanation)
Next, processing executed by the system controller 20 in the first embodiment will be described. Schematically, when displaying a search result for setting a destination or the like, the system controller 20 selects a facility that satisfies the search condition by the number of parking points P included in the facility information (hereinafter, “number of parking points”). Np ")), the higher the number, the higher the priority. By doing in this way, the system controller 20 presents the facility where parking is easy, and improves the convenience.

  This process will be specifically described with reference to FIG. FIG. 2 is an example of a diagram illustrating functional blocks of the system controller 20. As shown in FIG. 2, the system controller 20 includes a search condition specifying unit 201, a search unit 202, and a search result output unit 203. Hereinafter, processing executed by each of these elements will be described.

  First, processing executed by the search condition specifying unit 201 will be described. The search condition specifying unit 201 specifies the search condition based on the input information supplied from the input device 60. For example, in the case of a name search that performs a search based on a facility name, the search condition specifying unit 201 inputs a keyword corresponding to all or part of the facility name of a desired facility (hereinafter also referred to as “search character string”). And the designation of the area in which the facility exists and / or the designation of the genre to which the facility belongs is appropriately accepted. In this case, the search condition specifying unit 201, in this case, the above-described search character string, the specified area (hereinafter referred to as “specified area”), and the specified genre (hereinafter referred to as “specified genre”). Is specified as a search condition.

  Next, processing executed by the search unit 202 will be described. The search unit 202 extracts facilities satisfying the search condition (hereinafter referred to as “corresponding facility”) from the facility information database stored in the data storage unit 36. For example, in the case of the above-described name search, the search unit 202 extracts a facility that includes the input keyword in the facility name and exists in the designated area and belongs to the designated genre as the relevant facility.

  Next, processing executed by the search result output unit 203 will be described. The search result output unit 203 determines the order (hereinafter simply referred to as “display order”) of displaying the relevant facility based on the number Np of parking points included in the facility information of the relevant facility. Then, the search result output unit 203 displays the corresponding facility on the display unit 40 as a search result based on the display order. Specifically, the search result output unit 203 sets a higher display order for a corresponding facility having a larger number of parking points Np. Then, when displaying the search result list (hereinafter, referred to as “search result list”), the search result output unit 203 displays the relevant facility having the larger number of parking points Np at the top of the search result list.

  By doing in this way, the system controller 20 can preferentially present the facility where parking is easy, and can improve a user's convenience.

  Note that the search result output unit 203 may determine the display order of these sounds in the order of 50 sounds or the order close to the current location when there are corresponding facilities with the same number of parking points Np.

(Display example)
Next, the display screen output by the display unit 40 in the first embodiment will be described with reference to FIG. In the following description, it is assumed that the navigation device 1 receives an input by a touch panel method as an example. In addition, “A”, “B”, and “C” in FIG. 3 indicate predetermined hiragana characters, respectively. The broken line frame indicates a virtual area.

  FIG. 3A shows an input screen display example when performing a name search. The display screen 70x includes an input display field 71 for displaying an input search character string, and a character input unit 72 using a touch panel. Furthermore, the display screen 70x includes a genre selection button 73 for shifting to a selection screen for a designated genre, an area selection button 74 for shifting to a selection screen for a specified area, and a candidate display button 75 for starting a search. .

  First, the user inputs a search character string by pressing a character portion in the character input unit 72. Here, as shown in the input display field 71, the user inputs “ABC entry”. In addition, the user presses the genre selection button 73 as necessary to display a selection screen for the designated genre. Then, the user performs input for selecting the designated genre from the selection screen. Similarly, the user presses an area selection button 74 as necessary to display a designated area selection screen. Then, the user performs input for selecting the designated area from the selection screen.

  When the user presses the candidate display button 75, the search condition specifying unit 201 specifies the search condition. Then, the search unit 202 identifies the corresponding facility based on the search condition, and the search result output unit 203 determines the display order of each corresponding facility.

  FIG. 3B shows an output screen display example after the name search is executed. The display screen 70y includes a search result list 76, a display switching button 77 for switching the display part of the search result list 76, and a scroll bar 78 for displaying the position of the display part in the entire search result list 76. And a map display unit 79.

  As shown in FIG. 3B, the display screen 70y displays a search result list 76 including a facility name display column 86 and a parking point number display column 87 from the corresponding facility having a higher display order. Here, the facility name display column 86 displays the facility name of the corresponding facility. Moreover, the parking point number display column 87 displays the parking point number Np of the relevant facility. In FIG. 3B, the corresponding facility “ABC station” having the largest number of parking points Np of 8 is displayed at the top of the search result list 76. In addition, when the user presses the display switching button 77, the search result output unit 203 appropriately displays the search result list 76 whose display order is fifth or later.

  The map display unit 79 displays the map of the position of one corresponding facility in the search result list 76 (here, “ABC station” located at the top of the search result list) on the map display unit 79. The icon 80 is an icon that displays the position of the parking point P of the corresponding facility “ABC station”.

  In this manner, the search result output unit 203 can facilitate selection of a candidate that is likely to be parked by displaying the relevant facility having a larger number of parking points Np at the top of the search result list 76. Moreover, the search result output part 203 can make a user grasp | ascertain clearly the parking point number Np by providing the parking point number display column 87. FIG.

(effect)
Next, the effect of the first embodiment will be described supplementarily using the comparative example of FIG. FIG. 4 shows an output screen display example after execution of the name search in the comparative example. The display screen 90 includes a search result list 76x, a display switching button 77x, a scroll bar 78x, and a map display unit 79x.

  As shown in FIG. 4, the display screen 90 displays the search result list 76x in order of the corresponding facilities in the order of 50 sounds or from the current location. Further, in FIG. 4, the corresponding facility “AB land” is selected from the search result list 76x. As a result, the map display unit 79x displays a peripheral map centered on “AB land”. The map display unit 79x displays the parking point P associated with the “AB land” with the icon 80x.

  As described above, in the comparative example, when the user selects an arbitrary corresponding facility in the search result list 76x, the map display unit 79x displays the parking point P associated with the corresponding facility with the icon 80x. Therefore, in the comparative example, the user cannot know the number Np of parking points associated with the corresponding facility unless the corresponding facility is selected from the search result list 76x. Further, in the comparative example, the search result list 76x is arranged according to a predetermined rule such as the alphabetical order of the facility names of the corresponding facilities. Therefore, in the comparative example, the higher-level corresponding facility in the search result list 76x does not necessarily have many parking points P. Therefore, the user may feel inconvenient when he / she wants to select the corresponding facility in the order of increasing number of parking points Np, that is, in the order in which parking is easy.

  Considering the above, in the first embodiment, the system controller 20 displays the search results in descending order of the number of parking points Np. Thereby, the user can select easily the applicable facility which is easy to park. In general, the number of parking points Np increases as a large facility with many parking lots and entrances. Further, when the parking point P is determined by counting the actions of a large number of users like the shared parking point Pu, the number of parking points Np increases as the facility is used by a large number of users. Therefore, in the first embodiment, the system controller 20 can present a facility or large facility used by a large number of people at the top of the search result list. Therefore, the system controller 20 can present the user with the corresponding facility more suitable for the user's intention as a search result.

(Processing flow)
Next, a processing procedure executed by the system controller 20 in the first embodiment will be described with reference to FIG. FIG. 5 is an example of a flowchart showing a processing procedure executed by the system controller 20 in the first embodiment. Here, as an example, a processing flow in the case of name search will be described. The system controller 20 repeatedly executes the process of the flowchart shown in FIG. 5 according to a predetermined cycle.

  First, the system controller 20 receives an input of a search character string (step S101). Specifically, the system controller 20 displays a display screen 70x as shown in FIG. 3A, for example, and accepts input of a search character string from the user. When the system controller 20 detects that the genre selection button 73 is pressed, the system controller 20 displays a selection screen for the specified genre and accepts the specified genre. Further, when the system controller 20 detects that the area selection button 74 has been pressed, the system controller 20 displays a designated area selection screen and accepts the designated area.

  Next, the system controller 20 determines whether or not a genre is specified (step S102). If the genre is designated (step S102; Yes), the system controller 20 adds the designated genre to the search condition (step S103). On the other hand, when the genre is not specified (step S102; No), the system controller 20 advances the process to step S104.

  Next, the system controller 20 determines whether an area is specified (step S104). If there is an area designation (step S104; Yes), the system controller 20 adds the designated area to the search condition (step S105). On the other hand, when there is no designation of an area (step S104; No), the system controller 20 proceeds to step S106.

  Next, the system controller 20 executes a search (step S106). Specifically, the system controller 20 extracts a facility that satisfies the search conditions specified in steps S101 to S105 as a corresponding facility.

  Then, the system controller 20 determines whether there is a corresponding facility (step S107). That is, the system controller 20 determines whether there is a facility that satisfies the search condition. When the corresponding facility exists (step S107; Yes), the system controller 20 sorts the corresponding facility based on the number of parking points Np (step S108). In other words, the system controller 20 sets the display order higher as the corresponding facility has a larger number of parking points Np. Then, the system controller 20 displays the search result (step S109). At this time, the system controller 20 displays the higher the number of parking points Np at the top of the search result list as the corresponding facility. As a result, the system controller 20 can preferentially present the facility that is easier to park to the user and improve the convenience of the user's selection.

  As described above, the navigation apparatus according to the present embodiment is installed in a vehicle and includes a storage unit, a search condition specifying unit, a search unit, and a search result output unit. The storage unit stores a candidate for a route guidance target location and a parking point related to the candidate. The search condition specifying means specifies the search condition based on a user operation. The search means searches for candidates that satisfy the search condition. The search result output means preferentially displays the search result as the candidate having a larger number of parking points associated with the candidate among the candidates satisfying the search condition. By doing in this way, the navigation apparatus can actively present candidates that are easy to park as search results. Therefore, the user can easily select a candidate that is easy to park as a target location, and convenience is improved. Also, many parking points are usually associated with large facilities where many people stop by. Therefore, the user can easily select a large-scale facility from the search result even when he / she goes for the first time.

[Second Embodiment]
Next, processing executed by the system controller 20 in the second embodiment will be described. Schematically, the system controller 20 determines the number of parking points Np for each type of parking point P (hereinafter referred to as “type parking point number Nps”) and which type of parking point number Nps is prioritized. The display order of the corresponding facility is determined based on the priority order (hereinafter referred to as “inter-class priority order”). Thereby, the convenience of the user's selection is further improved.

  This will be described in detail with reference to FIG. 2 again. Note that the processes executed by the search condition specifying unit 201 and the search unit 202 are the same as those in the first embodiment, and thus description thereof is omitted.

  First, the search result output unit 203 sets a higher display order for the corresponding facility having the highest number of classified parking points Nps with the highest priority between types. Next, as a result of the above-described processing, the search result output unit 203 determines the type having the second highest inter-class priority for the corresponding facility having the same display order, that is, the corresponding facility having the same number of types of parking points Nps. The higher the order of display, the higher the number of parking points Nps. Further, for the corresponding facilities having the same two types of parking points Nps as described above, the search result output unit 203 increases the display order for the corresponding facility having the third highest type parking point number Nps among the types of priorities. Set. The search result output unit 203 may determine the display order based on the order of the Japanese syllabary when there is a corresponding facility having the same number of types of parking points Nps. It may be set.

  Next, the search result output unit 203 displays the corresponding facility on the display unit 40 based on the display order determined by the above processing. In other words, the search result output unit 203 displays the higher the display order, the higher the corresponding facility.

  By doing in this way, the system controller 20 can improve a user's convenience further. For example, when the inter-class priority of the personal parking point Pi is set to be the highest, the system controller 20 preferentially presents the facility having the large number of personal parking points Pi to the user. Therefore, in this case, the system controller 20 can display the facilities that are frequently visited by the user of the mounted vehicle at the top of the search result list. In another example, when the inter-class priority of the shared parking point Pu is set to be the highest, the system controller 20 preferentially presents a facility having a large number of shared parking points Pu to the user. Therefore, in this case, the system controller 20 can display facilities that are frequently used by users of other navigation devices sharing the parking point P at the top of the search result list.

(Display example)
FIG. 6 shows an output screen display example of the second embodiment. Similar to the display screen 70y of the first embodiment, the display screen 70z includes a search result list 76, a display switching button 77 for switching the display part of the search result list 76, and a display part of the search result list 76. A scroll bar 78 for displaying the position and a map display unit 79 are provided. In FIG. 6, it is assumed that the priority between types is set in the order of the personal parking point Pi, the shared parking point Pu, and the existing parking point Pa.

  As shown in FIG. 6, the search result list 76 includes a facility name display field 86, a personal parking point number display field 87a, a shared parking point number display field 87b, and an existing parking point number display field 87c, respectively. Prepare. The number of personal parking points display field 87a is a field for displaying the number of personal parking points Pi (hereinafter referred to as “number of personal parking points Npi”). The shared parking point number display column 87b is a column for displaying the number of shared parking points Pu (hereinafter referred to as “shared parking point number Npu”). The number of existing parking points display column 87c is a column for displaying the number of existing parking points Pa (hereinafter referred to as “the number of existing parking points Npa”).

  Then, at the top of the search result list 76, the corresponding facility “ABC station” having the highest number of individual parking points Npi with the highest inter-class priority “4” is displayed. In the second and third search result lists 76, the corresponding facility “ABC station building” and the corresponding facility “ABC station square park” with the number of private parking points Npi “3” are displayed. In FIG. 6, the corresponding facility “ABC station square building” has a higher number of shared parking points Npu having the second highest priority among types than the corresponding facility “ABC station square park”. Therefore, the corresponding facility “ABC station square building” is displayed higher than the corresponding facility “ABC station square park”. In the fourth search result list 76, the corresponding facility “ABC station front mass retailer” having the fourth highest number of personal parking points Npi is displayed. When the search result output unit 203 detects that the user has pressed the display switching button 77, the search result output unit 203 appropriately displays the search result list 76 with the display order of the fifth or later.

  The map display unit 79 displays a map of the surrounding area of the corresponding facility “ABC station” having the highest display order. Here, the icon 80a displays the position of the personal parking point Pi. The icon 80b displays the position of the shared parking point Pu. The icon 80c displays the position of the existing parking point Pa.

  Thus, the system controller 20 can preferentially present a facility with a large number of personal parking points Pi to the user by setting the inter-class priority of the personal parking points Pi to the highest. Therefore, the system controller 20 can display the facilities that are frequently visited by the user of the mounted vehicle at the top of the search result list 76. In addition, the system controller 20 displays the number of individual parking points Nps by the individual parking point number display column 87a, the shared parking point number display column 87b, and the existing parking point number display column 87c. Therefore, the user can easily grasp the number Nps of type parking points of each corresponding facility from the search result list 76, and the convenience of selection is improved.

(Processing flow)
Next, the processing flow of the second embodiment will be described with reference to FIG. 5 again. In the second embodiment, the system controller 20 sorts the corresponding facilities based on the priority between types and the number of types of parking points Nps instead of the processing in step S108 after executing steps S101 to S107. Determine the display order. And the system controller 20 displays a search result similarly to step S109.

[Modification]
Hereafter, each modification of a present Example is demonstrated. These modifications can be applied to the above-described embodiments in any combination.

(Modification 1)
In FIG. 5 and the like, the system controller 20 determines the display order of the search result of the name search based on the number of parking points Np or the number of type parking points Nps. However, the search target to which the present invention is applicable is not limited to this. Specifically, the system controller 20 searches for a facility search based on a telephone number (telephone number search), or a facility search based on a genre (genre search), or other search results, instead of a name search. Alternatively, the processing of the first or second embodiment may be executed.

  In this case, the system controller 20 preferentially displays the corresponding facility obtained based on various searches as the number of parking points Np increases. Alternatively, the system controller 20 preferentially displays the corresponding facilities obtained based on various searches as the number of classified parking points Nps having a higher classification priority is larger.

(Modification 2)
The system controller 20 may execute the processes of the first and second embodiments only when there is an explicit instruction from the user. In this case, for example, the system controller 20 further displays an instruction button for displaying the search result based on the number of parking points Np or the number of types of parking points Nps on the display screen 70x in FIG. Then, the system controller 20 displays the search result list by arranging the corresponding facilities based on the number of parking points Np or the number of types of parking points Nps only when the pressing of the instruction button is detected. This also allows the system controller 20 to improve user convenience.

(Modification 3)
In the display screen 70y of FIG. 3B, the system controller 20 displays the parking point number Np of each corresponding facility in the parking point number display column 87 as a number. Instead of this, the system controller 20 may display the number of parking points Np of the relevant facility in each search result list 76 such that a graph such as a bar graph can be grasped sensuously. Similarly, the system controller 20 senses the display in the personal parking point number display column 87a, the shared parking point number display column 87b, and the existing parking point number display column 87c in the display screen 70z of FIG. Display that can be grasped visually.

(Modification 4)
In the second embodiment, the system controller 20 determines the types of parking points P as personal parking points Pi, shared parking points Pu, and existing parking points Pa. However, the kind of parking point P to which the present invention is applicable is not limited to this. Instead of this, the system controller 20 may classify the parking points P in more detail. Alternatively, the system controller 20 may classify the parking points P into two types. Even in these cases, the system controller 20 sets the priority between types for the type of each parking point P, and the larger the number Nps of type parking points of the type with higher priority between types, the corresponding facility of the search result. Set to a higher display order.

(Modification 5)
In the second embodiment, the system controller 20 preferentially displays the corresponding facility as the number of classified parking points Nps having a higher priority between types is larger. However, the method to which the present invention is applicable is not limited to this. Instead, the system controller 20 performs predetermined weighting on the number of classified parking points Nps based on the priority between types, and sums the weighted number of various types of parking points Nps (hereinafter simply referred to as “summed value G”). The corresponding facility may be preferentially displayed as the value of “)” increases.

  This will be specifically described with reference to FIG. Here, the weighting coefficient for the number of individual parking points Npi is “3”, the weighting coefficient for the number of shared parking points Npu is “2”, and the weighting coefficient for the number of existing parking points Npa is “1”. In this case, the total value G of the corresponding facility “ABC station” is “18”, the total value G of the corresponding facility “ABC station building” is “13”, and the total value G of the corresponding facility “ABC station square park” is “10”. The total value G of the facility “ABC station front mass retailer” is “12”. Therefore, in this case, the display order of the relevant facility “ABC station square park” and the relevant facility “ABC station square retail store” is switched.

  As described above, the system controller 20 can also present the search result to the user in consideration of the type of the parking point P by determining the display order of the corresponding facility based on the total value G.

(Modification 6)
In the description of the parking point P in the section [General configuration], when there are a plurality of entrances for one parking lot, the number Np of parking points is counted by the number of the entrances. Instead, the number of parking points Np may be counted by the number of parking lots. That is, the parking point number Np is counted by 1 for the parking lot even when there are a plurality of entrances to one parking lot.

  The present invention can be suitably applied to a vehicle navigation device, a PND (Personal Navigation Device), and other terminals having a navigation function.
