This navigation device 100 functions as a facility information display device in the present invention.

  Next, the configuration of the server 200 will be described with reference to FIG. FIG. 3 is a schematic diagram illustrating a configuration of the server 200.

  The server 200 is, for example, a computer, and includes a CPU 210, a memory 211 such as a RAM and a ROM, a hard disk 212, an output device 213 such as a display, an input device 214 such as a keyboard and a mouse, and a communication device 215.

The communication device 215 is configured to be able to transmit and receive with the communication device 38 of the navigation device 100. When the CPU 210 receives a facility information request regarding a predetermined facility from the navigation device 100, the CPU 210 acquires the facility information regarding the predetermined facility from the hard disk 212 and transmits it to the navigation device 100. This process is realized by the CPU 210 executing a program. This server 200 functions as a facility information providing server in the present invention. Below, the facility information provision method to the navigation apparatus 100 by the server 200 is demonstrated.

[Facility information provision method]
The facility information providing method by the server 200 will be specifically described.

  First, the user indicates an instruction position such as the vehicle position or destination (hereinafter referred to as “user instruction position”), the type of facility to be searched in the vicinity of the user instruction position, and the display order of the facility (for example, charge The designation of the order of cheapness is input to the navigation device 100. The system controller 20 transmits the user-designated position, the type of facility, and information specifying the display order of the facility to the server 200 via the communication device 38 as a facility information request. Hereinafter, the information on the user-designated position will be referred to as “user-designated position information”, the information on the facility type will be referred to as “facility type information”, and the display order designation information of the facility will be referred to as “display order designation”. It will be referred to as “information”. In the following, it is assumed that the user has designated a parking lot as a facility to be searched.

  The server 200 receives the facility information request from the navigation device 100 via the communication device 215. In the server 200, the CPU 210 acquires facility information from the server DB of the hard disk 212 based on the user-instructed position information and facility type information. Here, since the designated facility type is a parking lot, the CPU 210 acquires parking lot information within a certain range including the user-instructed position from the server DB. Hereinafter, this will be specifically described with reference to FIG.

  FIG. 4A is an example of facility information stored in the server DB, and FIG. 4B is an example of parking lot information acquired from the server DB.

  As shown in FIG. 4A, the server DB stores various facility information such as a restaurant and a convenience store in addition to a parking lot. The facility information includes, for example, facility name information indicating the facility name and the type of facility, position information indicating the location of the facility, and other information indicating other information about the facility. The position information is indicated by, for example, latitude and longitude. In the example shown in FIG. 4A, (latitude, longitude) = (Xij, Yij) (i: English letter, j: number). Moreover, in the example shown to Fig.4 (a), when facility information is parking lot information, the parking fee per unit time is shown as other information.

  CPU210 acquires the parking lot information in the fixed range containing a user instruction | indication position from server DB. An example of the parking lot information acquired from the server DB in this way is shown in FIG. Here, for example, when the display order designation information is in the order of the lowest parking fee, the CPU 210 searches the parking lot information acquired from the server DB in ascending order based on the other information in the parking lot information. The list is created, and the created list of parking lot information is transmitted to the navigation device 100 via the communication device 215.

  The navigation device 100 receives a list of parking lot information from the server 200 via the communication device 38. In the navigation device 100, the system controller 20 displays the received parking lot information list on the display screen of the display 44 together with the map data (see FIG. 7 described later). Thereby, the user can recognize the parking lot near a user instruction | indication position in order with a cheap parking charge.

  Here, there are more parking spaces in urban areas than in suburban areas. Therefore, the number of parking lot information acquired from the server DB in the server 200 is larger when the user-instructed position is in the urban area than when the user-instructed position is in the suburban area. Therefore, when the user-instructed position is in an urban area, it takes time to search for and list parking information in ascending order of parking fees.

  Therefore, in the facility information providing method according to the embodiment, the CPU 210 of the server 200 acquires the parking lot information within a certain range including the user designated position from the server DB according to the user designated position. The number of information is changed. Specifically, the CPU 210 determines whether the user instruction position is in the urban area or the suburb area, and when the user instruction position is in the city area, the user instruction position is in the suburb area. In comparison, the certain range for acquiring the parking lot information is reduced. Hereinafter, description will be made with reference to FIGS.

  First, a case where the user instruction position is in the suburb will be described.

  FIG. 5 shows an example of the acquisition range of the parking lot information when the user-instructed position is in the suburbs. In the following, it is assumed that the user-instructed position is the own vehicle position as an example, and is indicated by an arrow pp. The CPU 210 of the server 200 acquires parking lot information within a predetermined range including the user instruction position from the server DB. For example, the CPU 210 acquires parking lot information within a certain distance r1 centered on the user instruction position from the server DB. Here, the fixed distance r1 is a predetermined adaptation value, and is set to about 5 km, for example.

  Here, FIG. 6 shows the parking lot information acquired from the server DB when the constant distance is r1. As shown in FIG. 6, at this time, three pieces of parking lot information, that is, parking lot information of the parking lots PB1, PB2, and PB3 are acquired. Then, the CPU 210 searches and lists the acquired parking lot information in ascending order of the parking fee, and transmits the list to the navigation device 100. In the navigation device 100, the system controller 20 displays the received parking lot information list on the display screen of the display 44. An example of the display screen at this time is shown in FIG. In the example shown in FIG. 7, a list of parking lot information is shown as a list DLs.

  Next, a case where the user instruction position is in an urban area will be described.

  FIG. 8 shows an example of an acquisition range of parking lot information when the user-instructed position is in an urban area. Also in this case, the CPU 210 of the server 200 acquires parking lot information within a certain distance centered on the user-instructed position from the server DB.

  Here, FIG. 9 shows the parking lot information acquired from the server DB when the constant distance is set to the same r1 as in the suburbs. As shown in FIG. 9, nine parking lot information is acquired at this time, ie, the parking lot information of parking lots PA1-PA9 is acquired. Therefore, in this case, it takes time for the CPU 210 to search and list the acquired parking lot information in ascending order of the parking fee as compared with the case where the user-instructed position is in the suburbs.

  Therefore, in this embodiment, when the user instruction position is in the urban area, the CPU 210 sets the fixed distance to r2 smaller than r1 and sets the parking lot information when acquiring the parking lot information from the server DB. Is obtained from the server DB (see FIG. 8). Here, the fixed distance r2 is a predetermined adaptation value, and is set to about 1 km, for example. The parking lot information acquired from the server DB at this time is shown in FIG. As shown in FIG. 10, at this time, three pieces of parking lot information are acquired, that is, the parking lot information of the parking lots PA1, PA2, and PA3 is acquired. It takes less time to search and list the three parking lot information in ascending order of the parking fee than to search and list the nine parking lot information in ascending order of the parking fee. CPU210 will transmit to the navigation apparatus 100, if it searches and lists the acquired three parking lot information in order with the cheapest parking charge. In the navigation device 100, the system controller 20 displays the received parking lot information list on the display screen of the display 44. An example of the display screen at this time is shown in FIG. In the example shown in FIG. 11, a list of parking lot information is shown as a list DLs2.

  In this way, when the CPU 210 obtains parking lot information within a certain distance centered on the user designated position from the server DB, if the user designated position is in the urban area, the user designated position is in the suburban area. The fixed distance is set to be smaller than that of a certain case. By doing in this way, the number of parking lot information acquired from server DB can be decreased, and it can suppress that it takes time to search for parking lot information according to various conditions.

  In the above-described embodiment, the CPU 210 acquires the parking lot information within a certain distance centered on the user instruction position from the server DB. However, the range for acquiring the parking lot information is not limited to this. . In short, the CPU 210 may acquire the parking lot information within a certain range including the user instruction position from the server DB. Therefore, for example, as shown in FIG. 12, the parking lot information in the area Area1 surrounded by a square including the user-instructed position may be acquired from the server DB. In this case, the area Area1 surrounded by the square is set smaller when the user-instructed position is in the urban area than in the case where the user-instructed position is in the suburban area. Specifically, the lengths L1 and / or L2 that define the area of the range Area1 are set to be small.

  Further, in the above-described embodiment, the CPU 210 changes the certain distance according to the user designated position when acquiring parking lot information within a certain distance centered on the user designated position from the server DB. . However, the embodiment to which the present invention is applicable is not limited to this. Instead of doing this, the CPU 210 acquires the parking lot information that is equal to or lower than a predetermined parking fee (hereinafter referred to as “reference fee”) based on other information in the server DB. The reference fee may be changed according to the user instruction position.

  Specifically, the CPU 210 obtains, from the server DB, parking lot information that is within a certain distance r1 centered on the user-designated position and that is equal to or less than the reference fee. Here, the reference fee is set smaller when the user-instructed position is in the urban area than when the user-instructed position is in the suburban area.

  For example, it is assumed that the reference fee is set to 1000 yen when the user-instructed position is in a suburb, and the reference fee is set to 400 yen when the user-instructed position is in an urban area.

  In this case, when the user-instructed position is in the suburbs, all other information of the parking lot information shown in FIG. 6 is 1000 yen or less, and therefore is within a certain distance r1 with the user-instructed position as the center. All the parking lot information is acquired from the server DB, that is, the parking lot information of the parking lots PB1, PB2, and PB3 is acquired from the server DB. On the other hand, when the user-instructed position is in an urban area, the parking lot information whose parking fee is 400 yen or less is acquired from the server DB among the parking lot information shown in FIG. That is, the three parking lot information of the parking lots PA2, PA4, and PA6 is acquired from the server DB. For example, when the server 200 searches and lists these parking lot information in ascending order of charge, the list at this time is in the order of parking lots PA6, PA2, and PA4.

  Even if it does in this way, it can suppress that search of the parking lot information according to various conditions takes time. In this method, parking information with a low parking fee can be preferentially acquired from facility information within a certain range including the user-instructed position. Therefore, this method is particularly useful when the user wants to find a parking lot that is as cheap as possible even if it is slightly distant from the user indication position.

  As can be seen from the above description, in the facility information providing method according to the present embodiment, when the parking lot information within a certain range including the user designated position is obtained from the server DB, it is obtained according to the user designated position. Change the number of parking lot information. By doing in this way, it can suppress that the time concerning the search according to various conditions changes with a user instruction | indication position.

  Here, the CPU 210 may perform the method of acquiring the parking lot information based on the distance from the user-instructed position described above and the method of acquiring the parking lot information based on the reference fee. Needless to say.

  Furthermore, the CPU 210 performs a combination of these methods, among a method for acquiring parking lot information based on the distance from the user-instructed position, and a method for acquiring parking lot information based on the reference fee. Which method is given priority may be changed according to a request from the user. In this case, in accordance with an instruction from the user, the CPU 210 changes the weighting for each of a fixed distance (hereinafter referred to as “reference distance”) centered on the user instruction position and the reference fee.

  FIG. 13 shows a display screen of the navigation device 100 when the user gives a weighting instruction.

  In the example shown in FIG. 13, the navigation device 100 displays on the display screen of the display 44 the coordinate axis with the horizontal axis as the distance and the vertical axis as the parking fee. Here, it is assumed that the display 44 is a touch panel and also functions as the input device 60. The system controller 20 of the navigation device 100 transmits information indicating weights for the reference distance and the reference fee to the server 200 according to the position touched by the user on the display screen of the display 44.

  For example, when the user selects the position UP1 on the display screen, the weights for the reference distance and the reference fee are both determined to be the same. In this case, when the user-instructed position is in the suburbs, the server 200 acquires from the server DB the parking lot information that is within the reference distance r1 and that is less than or equal to the reference fee of 1000 yen. On the other hand, when the user-instructed position is in an urban area, the server 200 acquires parking information that is within the reference distance r2 and that is less than or equal to the reference charge of 400 yen from the server DB.

  When the user selects the position UP2 on the display screen, the weight for the reference fee becomes smaller, that is, the reference fee becomes higher than when the position UP1 is selected. For example, when the user-instructed position is in a suburb, the server 200 acquires parking lot information that is within the reference distance r1 and that has a reference charge of 2000 yen or less from the server DB. On the other hand, when the user-instructed position is in an urban area, the server 200 acquires parking lot information that is within the reference distance r2 and that has a reference charge of 1000 yen or less from the server DB.

  By doing in this way, the server 200 can acquire the parking lot information more suitable for the user's request in terms of the distance from the user instruction position and the parking fee.

[Other embodiments]
Next, a facility information providing method according to another embodiment will be described. In the facility information providing method according to another embodiment, a facility information providing method in a case where all user-instructed positions received from a plurality of vehicle navigation devices within a predetermined time are at the same position will be described. Hereinafter, a description will be given with reference to FIG.

  FIG. 14 shows an example in which the server provides parking lot information to a plurality of vehicle navigation devices.

  In the example illustrated in FIG. 14, the server 200 receives user-instructed position information from the navigation devices 100 of the vehicles CA1, CA2, and CA3 within a predetermined time, and these user-instructed position information all indicate the same position. It shall be. Such a situation occurs, for example, when there is a venue where some event is held at the user-designated position and each user on the vehicles CA1, CA2, CA3 is going to the location.

  In this case, the parking lot information acquired from the server DB is the same. An example of the parking lot information acquired at this time is shown in FIG. However, when the server 200 transmits the parking lot information shown in FIG. 15 as it is to the navigation device 100 of each vehicle, for example, the parking lot PC6 having the lowest parking fee among them is used. There is a risk that some of the vehicles CA1, CA2, and CA3 cannot be parked due to congestion.

  Therefore, in the facility information providing method according to another embodiment, the server 200 receives user-instructed position information indicating the same user-indicated position from the navigation devices 100 of a plurality of different vehicles within a predetermined time. The parking lot information to be provided is made different for each vehicle navigation device. Here, the predetermined time is a suitable value, and is set to 3 minutes, for example.

  Specifically, when the server 200 receives user-instructed position information indicating the same user-indicated position from the navigation devices 100 of the vehicles CA1, CA2, and CA3 within a certain period of time, the server 200 falls within a certain range including the user-indicated position. Parking information (see FIG. 15) is obtained from the server DB.

  When the server 200 transmits the parking lot information to the navigation devices 100 of the vehicles CA1, CA2, and CA3, the server 200 does not transmit all the parking lot information shown in FIG. 15 to the navigation devices 100 of the vehicles. The parking lot information transmitted for each vehicle is different from each other. For example, as shown in FIG. 14, the server 200 transmits the parking lot information of the parking lots PC1 and PC2 to the navigation device 100 of the vehicle CA1, and the parking lot PC3 to the navigation device 100 of the vehicle CA2. The parking lot information of PC4 is transmitted, and the parking lot information of parking lots PC5 and PC6 is transmitted to the navigation device 100 of the vehicle CA3. Here, when the user designated position is the destination, the server 200 preferentially transmits the parking lot closest to the current position of each vehicle when transmitting the parking lot information to each vehicle. You may do that.

  Thus, it is possible to prevent a specific parking lot from becoming crowded by making the facility information provided to the navigation device of each vehicle different.

[Modification]
It should be noted that the present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the gist or concept of the invention that can be read from the claims and the entire specification. A display device is also included in the technical scope of the present invention.

  For example, in each of the embodiments described above, the other information in the parking lot information is information on a parking fee per unit time, but is not limited thereto. Other information may include information indicating whether the parking lot is full in addition to the parking fee information. Moreover, in each Example mentioned above, although the server 200 is acquiring the parking lot information from server DB based on the distance from a user designation position and / or a parking fee, it is not restricted to this. Instead of or in addition to this, the parking lot information includes information on the number of empty parking lots as other information, and the server 200 is within a certain distance centered on the user-designated position, and parking You may acquire the parking lot information from which the vacant number of parking lots is more than predetermined number from server DB. Here, when the user instruction position is in the urban area, the predetermined number is set larger than in the case where the user instruction position is in the suburban area.

  The server 200 may increase the certain distance until a parking lot is found when the parking lot information within a certain distance centered on the user-designated position is acquired from the server DB. However, in some cases, if a certain distance is unnecessarily widened, it takes time to display information to the user accordingly. Examples of such a case include a case where no free parking lot is found in an urban area, or a case where no parking lot itself is found in a mountainous area in a suburban area. Therefore, in such a case, the upper limit of the fixed distance or the upper limit of the search time is determined in advance, and if it is not found within these upper limit ranges, the server 200 sends information to that effect to the navigation device 100. Then, the navigation device 100 may display “time up” or “not found”. As a result, the user can avoid wasting time by performing a search at a low possibility of parking, and can take a more significant action such as changing the user-instructed position such as the destination. It becomes.

  Moreover, in each Example mentioned above, although it is supposed that the parking lot information is acquired from server DB by the server 200, it is not restricted to this. Instead of doing this, the navigation device 100 may have a database storing facility information, and may acquire parking lot information from the database based on the user-instructed position. At this time, the navigation device 100 changes the number of pieces of parking lot information to be acquired according to the user instruction position, as in the above-described embodiments. Also by this, it can suppress that the time concerning the search according to various conditions changes with a user instruction | indication position.

  Further, in each of the above-described embodiments, the example using the parking lot information is given. However, the present invention is not limited to this. It goes without saying that is applicable. For example, in the case of using facility information relating to a hotel, the information on the accommodation fee per night corresponds to the information corresponding to the parking fee information in the parking lot information described above.
