Description

  The present invention relates to a parking lot navigation system that performs various types of navigation on a parking lot situation for a user in a large-scale parking lot.

  Conventionally, in a large-scale parking lot, for example, a place with an empty cab is displayed for each block (floor) in the vicinity of an entrance and guided to an empty cab. In addition, for example, an empty vehicle compartment is displayed near the empty vehicle compartment.

  However, in this case, it is difficult for the user to find an empty cab while driving, and the actual situation has changed from the vacancy information obtained near the entrance etc. while there is traffic jam in the hall. Or after parking, it was difficult to know where the car was stopped.

  In order to solve one of the various problems in a large-scale parking lot as described above, as a technique related to grasping the situation of the parking lot, conventionally, for example, information on the position of the vehicle acquired over time from a probe vehicle A technique (see Patent Document 1) is known that determines the full availability of a parking lot by extracting information in association with.

  However, even if it becomes achievable that the above technique determines the full availability of the entire parking lot even if there are few probe vehicles by associating with the information in the parking lot, it will enter the parking lot. It is not possible to reliably convey information about the empty vehicle room condition to each vehicle.

  In addition, instead of providing a display near the entrance, etc., it may be possible to give the user information regarding the vacant room conditions at the time of entry using an IC card, for example. If the congestion situation changes, the information given by the IC card or the like will no longer be useful.

JP2013-210706A

  The present invention has been made in view of the above-described points, and an object of the present invention is to provide a parking lot navigation system that enables accurate guidance according to changes in parking lot conditions.

  In order to achieve the above object, a parking lot navigation system according to the present invention provides at least full information (whether full or empty) to an access terminal by an information distribution server that can communicate with a movable access terminal. The guidance information regarding the inside of the parking lot is updated and distributed, and the position information of the access terminal can be acquired by the vehicle position recognition unit, and the acquired position information is transmitted to the information distribution server.

  In the parking lot navigation system described above, the information distribution server updates and distributes the guide information to the access terminal. On the other hand, the vehicle position recognition unit acquires the position information of the access terminal, and the acquired information Can be transmitted to the access terminal from the information distribution server in accordance with the change in the parking situation while recognizing the position of the moving access terminal. Become.

  In a specific aspect of the present invention, the information distribution server updates the guidance information in response to a selection instruction in the access terminal or information acquisition regarding a change in the situation in the parking lot. In this case, it is possible to distribute information flexibly and accurately in response to a request from a user who operates the access terminal or a change in the situation in the parking lot.

  In another specific aspect of the present invention, the information distribution server receives designation of a parking position as a selection instruction in the access terminal, and performs route guidance to the parking position for the access terminal that has accepted the designation. In this case, the user who operates the access terminal is surely guided to the target parking position according to the route guidance.

  In yet another aspect of the present invention, the information distribution server provides a threshold for limiting the number of vehicles that can be route-guided for each parking position, with respect to the designation of the parking position by the access terminal, Judgment is made. In this case, by limiting the number of vehicles that can be route-guided, it is possible to prevent a situation in which the route-guided vehicle cannot be parked at the target parking position.

  In still another aspect of the present invention, the information distribution server receives a walking mode position guidance command for storage position information indicating a position in the parking lot stored in the access terminal or the information distribution server at the time of parking or after parking. The route guidance in the walking mode from the position designated by the access terminal to the position in the parking lot stored as the storage position information is performed for the access terminal that has given the instruction. In this case, the user who operates the access terminal can be guided to the position of the parked vehicle.

  In still another aspect of the present invention, the information distribution server transmits guide information to the access terminal via the vehicle position recognition unit. In this case, the user can acquire the guide information through the network in the parking lot without using a communication line such as the Internet.

  In still another aspect of the present invention, the vehicle position recognizing unit includes a plurality of access points arranged at different positions in the parking lot. In this case, the transmission / reception state can be reliably formed without waste by appropriately arranging a plurality of access points in the parking lot according to the structure of the parking lot.

  In still another aspect of the present invention, the information distribution server predicts the congestion situation in the parking lot based on the information regarding the movement status of the vehicle acquired by the vehicle position recognition unit, and updates the guidance information based on the prediction result. . In this case, the vehicle that receives the guidance information from the information distribution server and parks it can more reliably avoid the congestion in the parking lot.

  As shown in FIG. 1, a parking lot navigation system 100 according to the present invention is incorporated in a parking lot overall management system 500, and includes a plurality of wireless access points AP <b> 1 to APN and an information distribution server 200. .

  The parking lot navigation system 100 is a system that performs various types of navigation related to the situation of the parking lot for the driver of each vehicle who is a user of the parking lot. In the present embodiment, the availability information is provided to the driver of the vehicle that owns the mobile terminals MT1 to MTM, which are mobile access terminals that can communicate with the information distribution server 200 via the wireless access points AP1 to APN. By updating and distributing guide information related to the parking lot including the information as needed, it is possible to transmit real-time information according to changes in the parking lot situation and to perform navigation to the parking lot.

  In addition, about each mobile terminal MT1-MTM, the various terminals which can communicate are applicable, and various things, such as a smart phone and a tablet terminal other than a mobile phone, are applied. In the mobile terminals MT1 to MTM, application software (applications) for receiving navigation from the parking lot navigation system 100 is incorporated in advance, and the user of the parking lot is mobile By appropriately starting up (activating) the application in the terminal, the guidance information by the parking lot navigation system 100 is received and navigation is performed. Moreover, it is good also as what makes the said car navigation system function as a mobile terminal by incorporating the application or the program equivalent to an application in the vehicle-mounted car navigation system. However, when using an in-vehicle fixed type car navigation system, it can be used only in a vehicle and cannot be used for navigation to a person described later.

  Among the parking lot navigation system 100, a plurality of wireless access points AP1 to APN maintain a state where they can be reliably transmitted to and received from the mobile terminals MT1 to MTM that are access terminals that can move with each vehicle in the parking lot, and The mobile terminals MT1 to MTM are appropriately arranged according to the structure of the parking lot and the like so that the position information of the mobile terminals MT1 to MTM can be acquired. In addition, each of the wireless access points AP1 to APN can transmit the acquired location information about the mobile terminals MT1 to MTM to the information distribution server 200. That is, the wireless access points AP1 to APN function as a vehicle position recognition unit that recognizes the position of the vehicle in the parking lot.

  The information distribution server 200 distributes to the mobile terminals MT <b> 1 to MTM in a communicable state while updating guide information related to the parking lot including at least empty information at an appropriate timing. Various communication means can be applied between the information distribution server 200 and the mobile terminals MT1 to MTM. For example, the communication means may be performed through a communication line such as the Internet line. It is assumed that a state where communication is possible using the wireless access points AP1 to APN is formed.

  The overall management system 500 includes a parking management device 300 in addition to the parking lot navigation system 100 described above. The parking management device 300 is installed in each parking compartment or area, a parking control monitoring device 310 that is a main part of parking management, a vehicle sensor 320 that is installed in each compartment of the parking lot and determines the presence or absence of a vehicle. In accordance with the determination result of the vehicle sensor 320, a display lamp 330 is lit to display whether or not the passenger compartment is open, and performs general processing relating to parking lot management. That is, the parking control monitoring device 310 of the parking management device 300 grasps the total number of parked vehicles and the parking status such as the area for each floor through the vehicle sensor 320 and the lighting state of the indicator lamp 330 according to the parking status. Control to be.

  Here, as shown in the figure, the information distribution server 200 of the parking lot navigation system 100 is connected by wire or wireless so as to be communicable with the parking control monitoring device 310 of the parking management device 300. That is, the information distribution server 200 acquires the information source regarding the full / vacant information from the parking control monitoring device 310 among the various pieces of guidance information to be transmitted to the mobile terminals MT1 to MTM.

  Note that, as indicated by a broken line in the figure, a combination of the information distribution server 200 and the parking control monitoring device 310 may function as an information distribution server (integrated information distribution server 150).

  Hereinafter, with reference to FIG. 2, an overview of the use of the parking lot navigation system 100 in a parking lot in which the parking lot navigation system 100 according to the present embodiment is incorporated will be described.

  First, in the three-dimensional parking lot CP having a plurality of hierarchies as shown in FIG. 2A as an example of a parking lot, a portion of the three-dimensional parking lot CP near the entrance EN is partially enlarged in FIG. 2B. As shown, a signboard indicating that the parking lot navigation system 100 (see FIG. 1) operates with respect to the vehicle VE traveling on the road, that is, a communication range by the wireless access points AP1 to APN (same as above). A display object BB such as is installed. The driver of the vehicle VE using the three-dimensional parking lot CP activates an application incorporated in the mobile terminal MT owned by the driver with reference to the display object BB.

  In addition to the display object BB, in the vicinity of the entrance EN of the three-dimensional parking lot CP, as a conventional one that displays the parking status, for example, for each floor that displays full / vacant information for each floor of a parking lot of a plurality of floors A full sky lamp FL1 is fixedly installed.

  When the driver of the vehicle VE activates the mobile terminal MT within a communicable range in order to use the parking lot navigation system 100 (that is, to become a user of the parking lot navigation system 100), as shown in FIG. Various information is displayed on the display unit GG of the mobile terminal MT as the contents of the display screen G1 on the mobile terminal MT. Specifically, the contents of the display screen G1 include the name of the parking lot, fullness information on each floor, business hours, and parking fees. In addition, a button for setting conditions that can set conditions for determining a parking lot is also displayed. Of these display information, the button display part for setting conditions and the button display part indicating each floor (floor) are selectable (tapable), and the finger FN is used as shown by the broken line in the figure. You can select (tap).

  For example, as illustrated in FIG. 2B, when 3F (that is, the third floor) is selected (tapped) among the floors, as shown in the display screen G2 of the mobile terminal MT shown in FIG. The content is switched to the information distributed from the information distribution server 200 such as the availability information for each parking lot block on the selected floor. Here, as an example, the wireless access point AP is arranged at the branch point TP of each floor, and when passing through this branch point TP, the mobile terminal MT transmits the updated block via the wireless access point AP. Get availability information for each. When the user selects (tap) the B block portion appearing on the display screen G2 corresponding to the location after parking, a confirmation display is displayed as shown on the display screen G3 of the mobile terminal MT. When the confirmation is made (selection of “Yes”), the parking position is stored in the mobile terminal MT or the information distribution server 200.

  By storing the parking position, for example, as shown in FIG. 2D, the user appropriately displays information on the position where the vehicle is parked as shown on the display screen G4 in the mobile terminal MT. Therefore, it is possible to reduce the difficulty of finding a car when entering.

  In addition, in the vicinity of the branch point TP shown in FIG. 2 (C), in addition to the wireless access point AP, as a conventional display for displaying parking information such as fullness information, for example, the floor and the nearest upper floor A floor-specific full lamp FL2 that displays the full state of the floor is fixedly installed.

  The various processes in the parking lot whose overview has been described above are summarized as shown in the flowchart of FIG. Specifically, first, a process performed at the time of entry (step S1) is performed, then various processes in the field are performed (step S2), and further, a process at the time of parking is performed (step S3). The above is from the entrance of the vehicle to the completion of parking. In addition, after parking, a user who has once left his / her vehicle returns to the position where he / she has parked his / her vehicle again, and a process (step S4) for allowing the vehicle to enter the parking lot is performed. Is completed.

  Hereinafter, each process of the content of the navigation regarding the parking outlined in FIG.2 and FIG.3 etc. is demonstrated more concretely.

  First, with reference to FIG. 4 and FIG. 5, one specific example regarding the entrance of step S1 among each step shown in FIG. 3 is demonstrated. The application of the mobile terminal MT is activated, and a screen display as shown in FIG. 4A is made on the display unit GG. At this time, for example, various information such as the wide compartment, the light compartment, the outside, the vicinity of the exit, and the like can be displayed together according to preset conditions. Here, in the display shown in FIG. 4 (A), for example, when 3F (3rd floor) is selected (tapped) among the floors, in the floor diagram of 3F (3rd floor) as shown in FIG. 4 (B). Full / empty information is indicated in block units (A block to D block). Among these, for example, when a free C block is selected (tapped), full / vacant information is shown in the compartment unit (first to tenth compartments) as shown in FIG. 4C. Here, for example, when the ninth passenger compartment is selected (tapped), a route guidance (navigation) display operation is started in the mobile terminal MT as shown in FIG.

  In addition to the operations described above, as shown in FIG. 4E, when the camera switching button is selected (tapped) at the start of route guidance or before and after the start of the route guidance, the camera installed in the parking lot It may be possible to switch to an image display (not shown) and to switch to an image showing the selected parking position and its surroundings. That is, the parking position such as the state of the adjacent vehicle and the surrounding situation can be visually recognized from the image by the camera.

  Hereinafter, with reference to the flowchart of FIG. 5, an example of various processes regarding the main part of the above-described operation will be described. First, when an application is activated in the mobile terminal MT (step S101), the information distribution server 200 displays a full space display for each floor as shown in FIG. 4A via the mobile terminal MT. Along with (Step S102), the parking fee / business hours information is displayed (Step S103), and further, a condition setting button is displayed for setting the conditions for selecting the passenger compartment (Step S104). Here, when the condition setting button is tapped (step S105: Yes), the information distribution server 200 operates in accordance with this and each item (not shown) for setting is displayed (step S106). . Various items can be considered as items to be displayed. Here, as an example, the wide vehicle compartment, the vicinity of the exit, the light vehicle compartment, and the like can be selected as described above. When the passenger compartment is designated, the user may make the above selection appropriately according to his / her request, so that, for example, the one satisfying the selected condition may be preferentially displayed and designated. When the setting change is performed for the setting item displayed in step S106 (step S107: Yes), the information distribution server 200 performs a process of accepting the changed setting (step S108). When the processing of step S108 is performed, the status display processing of the vacancy information for each floor is performed based on the set condition (step S109). If the setting item displayed in step S106 is not changed (step S107: No), or if the condition setting button is not tapped in the first place (step S105: No), step S109 is performed without performing the setting change process. The status of each floor is displayed. Here, as illustrated in FIG. 4A, when an empty floor is selected (tapped) (step S110: Yes), as illustrated in FIG. 4B, for each area on the selected floor. When a situation display is made (step S111) and an empty area is selected (tap) (step S112: Yes), as shown in FIG. 4C, a cabin situation display is made (step S113). When a room is selected (tapped) (step S114: Yes), route guidance (in-place navigation) is started as illustrated in FIG. 4D (step S115).

  Next, with reference to the flowchart of FIG. 6, a specific example relating to the processing in step S2 among the steps shown in FIG. 3 will be described. While the vehicle VE is moving, the mobile terminal MT moves with the vehicle VE, but continues to check whether there is a connectable wireless access point AP (step S201), and there is a newly connectable wireless access point AP. (Step S201: Yes), the availability information is updated from the information delivery server 200 that has confirmed the passage of the mobile terminal MT via the wireless access point AP (Step S202). Further, the information distribution server 200 records the wireless access point AP that the mobile terminal MT has passed. That is, the movement history of the mobile terminal MT (vehicle VE) is recorded (step S203). Here, if the status of the floor on which the vehicle VE was trying to park has changed, and it has become clear from the newly delivered vacant information (step S204: Yes), another route guidance In other words, a process for updating the route information is performed (step S205). After the process of step S205, or when it is determined that the vehicle is not full in step S204 (step S204: No), the mobile terminal MT (vehicles) is connected to the wireless access point AP near the destination that is the planned parking location. VE) is confirmed (step S206), and the processing of steps S201 to S206 is repeated until it is confirmed that the vehicle has arrived at the planned parking location.

  Next, with reference to the flowchart of FIG. 7, a specific example relating to the parking process in step S3 among the steps shown in FIG. 3 will be described. As described above, in the present embodiment, the user can record the parking position so that the user can call the parking position as necessary after parking.

  First, as a premise, in the parking lot navigation system 100, in step S2, the movement history of the mobile terminal MT, that is, the vehicle VE is recorded (see, for example, step S203 in FIG. 6). (Step S301).

  The mobile terminal MT accepts a process for recording the parking position after parking (step S302), and when a selection (tap) is made for recording the parking position (step S302: Yes), the mobile terminal MT passes through the wireless access point AP. It is confirmed whether or not the parking position is selected in another vehicle compartment where the parking position does not match the position designated by the navigation (step S303). If it is determined in step S303 that it is another parking position (step S303: Yes), or if the selection for recording the parking position has not been made in step S302 in the first place (the user forgot to tap) (step) (S302: No), the parking lot navigation system 100 performs a process of estimating the parking position by using the nearest wireless access point AP of the vehicle VE, and determines or corrects whether or not the subsequent position guidance is possible (step S305). The content determined in step S305 is stored in the mobile terminal MT or the information distribution server 200 as parking position information including a history relating to vehicle movement (step S306).

  On the other hand, when the parking position coincides with the position designated by the navigation in step S303 (step S303: No), it is determined that the parking has been performed according to the navigation, and the parking position information is a history regarding the movement of the vehicle in step S301. At the same time, it is stored in the mobile terminal MT or the information distribution server 200 (step S306).

  As for the operation in step S302, for example, when a selection (tap) for recording the parking position is made a plurality of times, the information is corrected in step S304. At this time, all the correction contents may be recorded as being included in the movement history. In addition, for example, after parking, when the user leaves the vehicle with the mobile terminal MT, even if the user notices that he / she has forgotten to tap for setting the parking position, By accepting selection (tap) and storing the movement history, it may be possible to keep a record as information around the parked position.

  Further, even when a vehicle parked at a position different from the position designated by the navigation as described above is generated, in the overall parking lot management system 500, as described above, the vehicle sensor 320 provides independent independence. In addition, since the management regarding the full availability information of the passenger compartment is performed, there is no occurrence of a discrepancy with respect to the full availability information.

  Finally, with reference to FIG. 8 and FIG. 9, a specific example regarding the process at the time of participation of step S4 among each step shown in FIG. 3 is demonstrated. As shown in FIG. 8A, after parking, a user who has left his / her vehicle activates the application of the mobile terminal MT and is stored in the mobile terminal MT or the information distribution server 200 at the time of parking or after parking. The storage position information indicating the position of the vehicle in the parking lot can be displayed on the display unit GG. Further, when the user taps the guidance start button portion of the screen displayed on the display unit GG, the route guidance (navigation) display operation in the walking mode is performed as shown in FIG. 8B. Is started. Further, after the user arrives at the place where the user's vehicle VE is parked, the mobile terminal MT is appropriately operated, so that an exit route guidance (navigation) for entry in the vehicle mode as shown in FIG. 8C. ) Display operation is started in the mobile terminal MT.

  Hereinafter, with reference to the flowchart of FIG. 9, various processes performed for the above-described operation will be described. First, when the application of the mobile terminal MT is activated and a selection (tap) for calling the parking position is made (step S401: Yes), the memory indicating the position of the vehicle as shown in FIG. 8A is stored. The position information is displayed (step S402). Further, when the position guidance command for the walking mode is received by tapping the guidance start button (step S403: Yes), the information distribution server 200 sends the mobile terminal MT to the mobile terminal MT that has given the command. The route guidance in the walking mode from the designated position (for example, the current location of the mobile terminal MT) to the position of the own vehicle VE stored as the stored position information is performed (step S404). After the user arrives at his / her own vehicle VE by navigation in step S404 or without receiving navigation in the walking mode in step S403 (step S401: No), or for the parking position call in step S401 in the first place. (Step S401: No) After arriving at the vehicle VE, the mobile terminal MT is operated to select (tap) exit route guidance (navigation) in the vehicle mode (step S405). : Yes), the exit route guidance (navigation) display operation for participation in the vehicle mode as shown in FIG. 8C is started (step S406), the participation of the vehicle VE is completed, and the wireless access point AP performs When reaching out of the detectable range, the mobile terminal MT Cut off communication of, various types of processing is completed. If exit route guidance is not selected in step S405, the process ends with the entry of the vehicle VE without performing navigation.

  Of the above, regarding the display in step S402, the screen switching operation is appropriately performed together with the information update due to the passage of the wireless access point AP.

  Hereinafter, with reference to FIG. 10, an example of a calculation process of the number of guideable vehicles in the parking lot navigation system 100 will be described. In the parking lot navigation system 100, a threshold is set for the number of vehicles that can be guided, and based on the threshold, it is determined whether or not a parking position can be designated. That is, by limiting the number of vehicles that can be route-guided, the route-guided vehicles However, the situation where the vehicle cannot park at the target parking position is suppressed.

  10 (A) to 10 (H) are diagrams conceptually showing the number of vehicles that can be parked. In the drawing, the uppermost line shows the upper limit MX of the number of vehicles that can be parked. Moreover, the broken line in the figure indicates a threshold value TH that determines the number of units that can be guided. As illustrated, the threshold value TH is set to a position slightly smaller than the upper limit MX. In other words, it has some margin. As a result, there is a difference in the speed of movement among a plurality of vehicles to be parked. Controls are made so that the room can be provided. Further, in the figure, the inventory number P1 indicates the number of vehicles that are already parked, and the guidance number N1 indicates the number of vehicles that are being guided by the parking lot navigation system 100. That is, the guidance number N1 means the number of parking reservations. Therefore, the total of the inventory number P1 and the guidance number N1 is the total number of parking units including the reserved amount. In addition, the parking lot navigation system 100 can acquire information on the number of stocks P1 from the parking management device 300 (see FIG. 1), and information on the number of guided vehicles N1 can be grasped from the wireless access points AP1 to APN.

  Hereinafter, the above control will be specifically described with reference to FIG. In addition, here, as an example, each drawing such as FIG. 10A shows the number of vehicles that can be parked on one floor. First, in the situation shown in FIG. 10A, the sum of the inventory quantity P1 and the guidance quantity N1 shows a state considerably smaller than the threshold value TH. In this case, it is determined that the number of vehicles to be guided may be further increased, and the information distribution server 200 distributes the full / vacant information about the floor as “empty vehicle” to the mobile terminal MT. When the state shown in FIG. 10B is changed from the state shown in FIG. 10A, that is, when the number of guided vehicles N1 increases and becomes close to the threshold value TH, the information distribution server 200 Fully empty information is distributed as “congested” to the mobile terminal MT. When the number of guided vehicles N1 further increases and reaches the threshold value TH as shown in FIG. 10C, there is actually a vacant cabin for the margin, but the information distribution server 200 Fully empty information about the floor is distributed as “full” and no further route guidance is accepted. As a result, as shown in FIG. 10 (D), for example, even if the number of stocks P1 increases due to the presence of vehicles that park without receiving navigation, the number of guided vehicles N1 changes from the state of FIG. 10 (C). Since there is no margin and a margin is provided, it is possible to suppress the occurrence of a situation in which the passenger compartment is filled when the vehicle receiving navigation reaches the target floor. If the vehicle compartment designated by the navigation vehicle is parked first by another vehicle that does not accidentally receive navigation, another empty vehicle compartment on the same floor is searched again for guidance. It can also be corrected. In order to prevent such a situation from occurring, when a vehicle compartment to be parked is designated and navigation is started, it is treated as if a reservation for parking has been made, and the display of the reserved vehicle indicator lamp 330 (see FIG. 1) is displayed. It is also possible to prevent other vehicles from entering the passenger compartment by performing control to switch to a lit display indicating that there is already a vehicle and other vehicles cannot park.

  On the other hand, when the number of guided vehicles N1 is reduced as shown in FIG. 10E from the “congested” state shown in FIG. 10B, the information distribution server 200 is “congested” with respect to the mobile terminal MT. Update the full availability information to “empty car” and distribute it.

  Hereinafter, an aspect of one modification will be described with reference to FIG. In the state shown in FIG. 10 (F), even if a predetermined time (here, the time required for a normal vehicle to enter and park) elapses, the number of guided vehicles changes to N1 as shown in FIG. 10 (G). If there is no parking space, the parking lot navigation system 100 determines that the vehicle being navigated is parked in another cabin instead of the navigated cabin, or entered without parking, As shown in FIG. 10 (H), it may be determined that the number of guided vehicles N1 is small, and based on the result of this determination, the delivery content of the full / vacant information may be determined.

  As described above, in the aspect shown in FIG. 10, the fullness information for each floor to be delivered to the mobile terminal MT and the fullness information displayed on the full space-specific full-lights FL1 and FL2 are as follows. May be different. For example, with respect to the full / vacant information displayed on the full / full floor lamps FL1 and FL2, it is conceivable to display actual full / vacant information not considering the threshold value TH.

  As described above, in the parking lot navigation system 100 according to the present embodiment, the information distribution server 200 updates and distributes the guide information to the mobile terminal MT that is an access terminal. The location information of the mobile terminal MT is acquired by the wireless access points AP1 to APN functioning as the location recognition unit, and the acquired information is transmitted to the information distribution server 200. As a result, it is possible to transmit accurate guidance information from the information distribution server 200 to the mobile terminal MT according to a change in the parking lot situation while recognizing the position of the mobile terminal MT that moves.

  Further, as shown as a modified example in FIG. 11, the parking lot navigation system 100 of the parking lot management system may include a congestion situation prediction circuit 200 a that predicts the congestion situation in the information distribution server 200. That is, the information distribution server 200 is congested in the congestion state prediction circuit 200a based on the information on the movement of the vehicle entering the parking lot acquired from the parking control monitoring device 310 and each of the wireless access points AP1 to APN and the parking state information. The situation may be predicted, and route guidance (navigation) may be performed so as to avoid congestion in the parking lot based on the prediction result. For example, the degree of increase in each floor is predicted by calculating the rate of change in the number of stocks P1 and the number of guides N1 for each floor, and for floors with a large increase, the availability information delivered to the mobile terminal MT is more than usual. It is also possible to perform processing such as switching to “congestion” at an early stage.

  Although the present invention has been described with reference to the embodiments, the present invention is not limited to the above embodiments.

  For example, in the above description, various route guidance is performed by screen display on the mobile terminal MT. However, the present invention is not limited to this. For example, route guidance may be performed by voice. Moreover, it is good also as what uses a sound and a screen display together.

  Further, when the vehicle VE being guided (mobile terminal MT) has passed the position of the designated parking room, the guidance route may be searched again. In this case, for example, a mode in which the re-search is performed so as to re-guide to the nearest empty vehicle room in an empty vehicle room different from the previously specified vehicle room in consideration of the traveling direction of the vehicle VE being guided, etc. can be considered. .

  In addition, if the vehicle VE (mobile terminal MT) being guided does not park in the parking area designated by the vehicle VE (mobile terminal MT) and parks in another room, the reservation setting for the unparked room is performed. It is good also as what resets and guides another user immediately.

  Further, for example, in the above description, the location information about the mobile terminals MT1 to MTM is acquired by the wireless access points AP1 to APN and transmitted to the information distribution server 200, but various communication methods other than the wireless access points are used. For example, in-place GPS (indoor GPS) can be used. In addition, various wireless LAN wirings such as Wi-Fi, optical beacons, and the like may be used.

  The configurations, shapes, sizes, and arrangement relationships described in the above embodiments are merely schematically shown to the extent that the present invention can be understood and implemented. Therefore, the present invention is not limited to the described embodiments, and can be variously modified without departing from the scope of the technical idea shown in the claims.
