The parking prediction management method and apparatus described in Patent Document 1 identify whether a vehicle to enter a parking lot is a registered vehicle such as a monthly pole or a temporary use vehicle, and immediately permits entry when the vehicle is a registered vehicle. . On the other hand, when the vehicle is a temporary vehicle, the number of parking spaces required for the registered vehicle is predicted, and if there is enough room, admission is permitted.
Japanese Patent Laid-Open No. 5-120599

  The parking prediction management method and apparatus described in Patent Document 1 considers only statistical data such as the number of vehicles in and out and the number of vehicles entering and leaving the vehicle when predicting the number of parking spaces required for the registered vehicle. Does not consider the current position of For this reason, there is a problem that the prediction accuracy of the number of parking spaces required for the registered vehicle is low, and a state in which the registered vehicle and the temporary use vehicle tend to occur is likely to occur.

  In view of the above problems, an object of the present invention is to provide a parking lot management device, a parking lot management method, and a parking lot management system in which a state in which a registered vehicle and a temporary use vehicle are less likely to occur is generated.

  Based on the location information of the parking lot and the location information of the registered vehicle included in the GPS information sent from the issued registered vehicle, the parking lot that is the expected time required for the registered vehicle to reach the parking lot The arrival time is calculated for each registered vehicle that has issued. The registered vehicles that have been issued according to the parking lot arrival time are divided into a plurality of groups. The space securing time, which is the expected time until a new number of parking spaces equal to the number of registered vehicles included in the group, is newly vacated in the parking lot, using the delivery rate, which is the number of vehicles leaving the parking lot per unit time. Ask for each group. When the representative parking lot arrival time representing the parking arrival time of the registered vehicle included in the group is determined for each group, and the space securing time is shorter than the representative parking lot arrival time of the group in at least one group Prohibits the entry of temporary vehicles into the parking lot.

  By considering the position information of the registered vehicle included in the GPS information, a state where the registered vehicle and the temporary use vehicle are shared is less likely to occur.

  With reference to FIGS. 1 to 5, an embodiment of a parking lot management device, a parking lot management method, and a parking lot management system according to the present invention will be described.

  As illustrated in FIG. 1, the parking lot management system 100 includes a registered vehicle 1, a parking lot management device 20, and a parking lot device 30.

  The registered vehicle 1 is a regular, monthly, contracted vehicle such as a member, a cargo handling vehicle, or the like, and is a vehicle having a right to park in the parking lot 3. Although not shown, there are a plurality of registered vehicles in the parking lot 3, and these registered vehicles perform the same processing as the registered vehicle 1. In addition to the registered vehicle 1, a vehicle called a temporary use vehicle appears in this specification and claims. The temporary use vehicle is a vehicle that does not make a contract in advance and intends to use the parking lot 3 temporarily. When it is simply described as a vehicle, it means both a registered vehicle and a temporary use vehicle in principle.

  The registered vehicle 1 is equipped with the vehicle-mounted device 10 and a vehicle ID tag 110 in which vehicle ID information is stored. As illustrated in FIG. 2, the vehicle-mounted device 10 includes a GPS information acquisition unit 11, a storage unit 12, an OBD information acquisition unit 13, a transmission / reception unit 14, a time unit 17 that acquires current time information, and each of the internal and external devices 10. The control part 18 which controls each part of an apparatus and the onboard equipment 10 is included.

  A parking lot device 30 is installed in the parking lot 3. As illustrated in FIG. 3, the parking lot device 30 acquires time information by transmitting and receiving the vehicle ID information acquisition unit 31, the entry / exit gate unit 32, and the parking lot management device 20 to exchange information. The time part 34, the calculation part 35 which performs a required calculation process, the memory | storage part 36 which memorize | stores parking lot information, etc., and the control part 37 which controls the operation | movement of each part are included.

  The vehicle ID information acquisition unit 31 acquires vehicle ID information of a registered vehicle that is about to enter or leave the parking lot. For example, when the vehicle is a registered vehicle on which the vehicle ID tag 110 is mounted, the vehicle ID tag 110 is wirelessly communicated to acquire vehicle ID information. The number plate number may be read by a vehicle number recognition camera, and the number may be used as vehicle ID information.

  When the vehicle ID information acquisition unit 31 acquires vehicle ID information, the time unit 34 acquires time information. Based on the acquired vehicle ID information and the acquired time information, it is information about the number of vehicles stored, the number of vehicles stored, the number of vehicles stored, and the number of parking lots. The parking unit information including the inventory quantity information is generated by the calculation unit 35. The generated parking lot information is stored in the storage unit 36. The parking lot information is sent to the parking lot management apparatus 20 by the transmission / reception unit 33. The parking lot information may include other information related to the parking lot such as vehicle ID information and time information.

  The entry / exit gate unit 32 controls entry / exit of the vehicle according to the type of the vehicle and the parking lot being full. For example, if the vehicle to be stored is a registered vehicle, the entry is permitted, and if the vehicle to be stored is a temporary use vehicle, the processing described later is performed and the refusal / permission of the receipt sent from the parking management device 20 is performed. Depending on the determination result, the refusal or permission of the temporary vehicle storage is performed. Judgment whether the vehicle which is going to enter is a registered vehicle or a temporary use vehicle is performed based on the vehicle ID information which the vehicle ID information acquisition part acquired. If the parking lot is full, all vehicles will be refused.

  As illustrated in FIG. 4, the parking lot management device 20 includes a storage unit 21, a parking lot arrival time calculation unit 22, a group division unit 23, a space securing time calculation unit 24, a determination unit 25, a transmission / reception unit 26, and a shipping rate calculation. 29, an operation unit 210 that is input means such as a keyboard / mouse, a display unit 211 that displays various information, a time unit 212 that acquires time information, and a control unit 213 that controls the operation of each unit. The storage unit 21 includes a map / GPS database for identifying and displaying the position of the vehicle, an OBD database including the OBD information of each vehicle, personal identification information in a contract such as regular and monthly, and a customer including the position information of each parking lot. Management information, such as a database, vehicle equipment information, parking lot information, the distance between vehicle parking lots, parking lot arrival time, staying time, average staying time, shipping rate, space securing time, etc. are stored.

  A GPS information acquisition unit 11 (see FIG. 2), which is a GPS receiver of the vehicle-mounted device 10 mounted on the registered vehicle, communicates with the GPS satellite 5 to obtain GPS (Global Positioning System) information including position information for a certain period of time. Obtained every time (see step S1, FIG. 5). The acquired GPS information is stored in the storage unit 12 in association with the ID and time information of the registered vehicle. That is, time series data of GPS information is stored in the storage unit 12.

The OBD information acquisition unit 13 of the in-vehicle device 10 is connected to the OBD port of the vehicle, and acquires OBD (On Board Diagnosis) information including vehicle speed information (step S2). The OBD information includes information such as vehicle speed information, vehicle travel distance, CO ₂ emission amount, fuel amount, fuel injection amount, fuel consumption, engine speed, and remote operation information (for example, information related to ON / OFF of door contact). May be included as necessary. The acquired OBD information is associated with time information and stored in the storage unit 12. That is, time series data of OBD information is stored in the storage unit 12.

  The transmission / reception unit 14 of the vehicle-mounted device 10 sends the vehicle ID information, time information, and GPS information and OBD information stored in the storage unit 12 to the parking lot management device 20 via the communication network at regular intervals (step S3). . The GPS information and OBD information acquired from the GPS information acquisition unit 11 and the OBD information acquisition unit 13, respectively, instead of the GPS information and OBD information stored in the storage unit 12 may be sent directly to the parking lot management apparatus 20. The parking lot management apparatus 20 stores the received vehicle ID information, time information, GPS information, and OBD information in the storage unit 21.

  The parking lot arrival time calculator 22 (see FIG. 4) of the parking lot management device 20 is based on the location information of the parking lot and the location information of the registered vehicle included in the GPS information sent from the registered vehicle that has left the parking lot. A parking lot arrival time, which is an estimated required time until the registered vehicle reaches the parking lot, is calculated for each registered vehicle that has issued the vehicle (step S4). In this example, the parking lot arrival time is calculated using not only the location information of the parking lot and the location information of the registered vehicle, but also the vehicle speed information included in the OBD information. For example, the parking lot arrival time is calculated based on the following two expressions.

Distance between vehicle parking lots = ((x coordinate of position information of registered vehicle−x coordinate of position information of parking lot) ² + (y coordinate of position information of registered vehicle−y coordinate of position information of parking lot) ² + ( Z coordinate of position information of registered vehicle-z coordinate of position information of parking lot) ² ) ^1/2
Parking lot arrival time = distance between vehicle parking lots / vehicle speed The location information of the parking lot corresponding to the registered vehicle is obtained by referring to the customer database using the registered vehicle ID as a key. When there are a plurality of registered vehicles that have been issued, the parking lot arrival times of the registered vehicles are calculated. The calculated parking lot arrival time is sent to the group dividing unit 23 together with the vehicle ID. The calculated parking lot arrival time is stored in the storage unit 21 as part of the management information.

  For example, it is assumed that ten registered vehicles C1, ..., C10 registered in the same parking lot are out. Assume that the vehicle ID information of the registered vehicles C1,..., C10 is C1,. The parking lot arrival time of the registered vehicle C1 is 0.3 hours, the parking lot arrival time of the registered vehicle C2 is 0.4 hours, the parking lot arrival time of the registered vehicle C3 is 0.6 hours, and the parking lot of the registered vehicle C4 Arrival time is 0.8 hours, registration vehicle C5 parking lot arrival time is 1.7 hours, registration vehicle C6 parking lot arrival time is 2.5 hours, registration vehicle C7 parking lot arrival time is 2.9 hours, Assume that the parking lot arrival time of the registered vehicle C8 is calculated as 3.5 hours, the parking lot arrival time of the registered vehicle C9 is calculated as 3.8 hours, and the parking lot arrival time of the registered vehicle C10 is calculated as 3.9 hours. In this case, information (C1, 0.3), (C2, 0.4),..., (C10, 3.9 hours) is sent to the group dividing unit 23.

  The group dividing unit 23 divides the registered vehicles that have been issued according to the parking lot arrival time into a plurality of groups (step S5). For example, grouping is performed according to which of a plurality of predetermined ranges with respect to the parking lot arrival time. Group division information, which is information about groups, is sent to the space reservation time calculation unit 24. The group division information is, for example, the number of registered vehicles included in each group. The number of registered vehicles included in the group may be 0 or 1.

  In the above example, the registered vehicles C1 and C2 are within a 0.5 hour range (greater than 0 hours and within 0.5 hours or less), and the registered vehicles C3 and C4 are within a 1 hour range (from 0.5 hours). The registered vehicle C5 is within a 2-hour range (greater than 1 hour and within 2 hours or less), and the registered vehicles C6 and C7 are within a 3-hour range (greater than 2 hours and 3 hours). The registered vehicles C8, C9, and C10 belong to the 4-hour range (ranges greater than 3 hours and 4 hours or less). Therefore, the registered vehicles C1 and C2 are in the group G1 within 0.5 hours, the registered vehicles C3 and C4 are in the group G2 within 1 hour, the registered vehicles C5 are in the group G3 within 2 hours, and the registered vehicles C6 and C7 are The registered vehicles C8, C9, and C10 are divided into a group G5 within a 4-hour period, and the registered vehicles C8, C9, and C10 are divided into groups G5 within a 4-hour area.

  The space securing time calculation unit 24 is a vehicle that issues a space securing time, which is an estimated time until a number of parking spaces equal to the number of registered vehicles included in the group, are newly vacated in the parking lot, from the parking lot per unit time. It calculates | requires for every group using the delivery rate which is the number of (step S6). For example, the space securing time is obtained by dividing the number of registered vehicles included in the group by the shipping rate. The obtained space securing time is sent to the determination unit 25.

  The delivery rate is obtained by dividing the number of vehicles delivered in a certain time section by the time length of that time section. For example, as the time interval, a time interval from the time that is back by the average residence time to the present time is used. Here, the average residence time is an average time during which a vehicle stays in the parking lot in a certain time zone, and is calculated using past data such as entry / exit time information received from the parking lot apparatus. The shipping rate is calculated by the shipping rate calculation unit 29.

  For example, assume that the average residence time is 2 hours. It is assumed that the number of vehicles delivered from the parking lot during the past two hours is five. In this case, the shipping rate is 5/2 = 2.5. The number of registered vehicles C1, C2 included in the group G1 within 0.5 hours is two. Therefore, the space securing time for the group G1 is 2 / 2.5 = 0.8 hours. The number of registered vehicles C3 and C4 included in the group G2 within one hour is two. Therefore, the space securing time for the group G2 is 2 / 2.5 = 0.8 hours. The number of registered vehicles C5 included in the group G3 within two hours is one. Therefore, the space securing time for the group G3 is 1 / 2.5 = 0.4 hours. The number of registered vehicles C6 and C7 included in the group G4 within 3 hours is two. Therefore, the space securing time for the group G4 is 2 / 2.5 = 0.8 hours. The number of registered vehicles C8, C9, C10 included in the group G5 within the 4-hour area is three. Therefore, the space securing time for the group G5 is 3 / 2.5 = 1.2 hours.

  The representative parking lot arrival time representing the parking lot arrival time of the registered vehicle included in the group is predetermined for each group and stored in the storage unit 21. For example, when grouping is performed according to which of a plurality of predetermined ranges for the parking arrival time, the maximum value of the parking arrival time of each group is designated as the representative parking lot. Car arrival time. One of the minimum value of the parking lot arrival time range of each group, the average parking lot arrival time of the registered vehicles included in the group, or one of the parking arrival times of the registered vehicles included in the group It may be the arrival time at the parking lot.

  For example, the representative parking lot arrival time of the group G1 within 0.5 hours is 0.5 hour, the representative parking lot arrival time of the group G2 within one hour is one hour, and the representative parking lot arrival time of the group G3 within two hours 2 hours, the representative parking lot arrival time of the group G4 within 3 hours is 3 hours, and the representative parking lot arrival time of the group G5 within 4 hours is 4 hours.

  If at least one group has a space securing time shorter than the representative parking lot arrival time of the group, the determining unit 25 determines that the temporary use vehicle is prohibited from entering the parking lot (step S7). On the other hand, when the space securing time is longer than the representative parking lot arrival time of the group in all the groups, it is determined that the temporary use vehicle is allowed to enter the parking lot. The determination result is sent to the transmission / reception unit 26. This is because when the space securing time is shorter than the representative parking lot arrival time of the group, there is a possibility that there is no parking space when the registered vehicle included in the group reaches the parking lot.

  The transmission / reception unit 26 sends the determination result in the determination unit 25, that is, information indicating that entry is prohibited or information indicating that entry is permitted to the parking lot device 30.

  The entry / exit gate unit 32 of the parking lot apparatus 30 prohibits or permits entry of the temporary use vehicle into the parking lot 3 based on the received determination result (steps S8 and S9).

  Thus, by considering the position information of the registered vehicle included in the GPS information, a state in which the registered vehicle and the temporary use vehicle are difficult to occur is more unlikely to occur. Thereby, an empty parking space can be utilized more effectively.

Normally, the CO ₂ emission amount of a vehicle is 2.3 kg of CO ₂ emission per liter of gasoline and 2.6 kg of CO ₂ emission per liter of light oil using fuel amount, fuel consumption, mileage, etc. However, these are not actual emissions. In this example, the parking lot management apparatus 20 has received the OBD information, and the actual discharge amount can be obtained by analyzing the OBD information. Thus, grasping the operation tendency of the registered vehicles, and can perform energy saving operation (CO ₂ reduction operation) instruction better.

[Modifications, etc.]
You may display on the display part 211 the position of a registration vehicle, the position of a parking lot, a parking lot arrival time, space securing time, etc. Thereby, it becomes possible for the administrator of the parking lot management system to manually determine whether to permit or reject entry of the temporary use vehicle by operating the operation unit 210 after confirming the situation.

  A plurality of parking lots may exist in addition to the parking lot 3. In this case, the parking lot management device 20 manages each of the plurality of parking lots in the same manner as the parking lot 3.

  In the above example, the arrival time of the parking lot is calculated by dividing the linear distance between the registered vehicle and the parking lot by the vehicle speed. However, this is not the straight distance, but the distance determined by the location of the registered vehicle and the parking lot. The parking lot arrival time may be calculated by dividing the vehicle speed by the vehicle speed.

  In the above example, when calculating the parking lot arrival time, the vehicle speed information included in the OBD information sent from the registered vehicle is used, but instead of this, the average value of the time zone with the vehicle speed information or The vehicle speed according to the road condition in the area where the registered vehicle is located may be used. Therefore, the vehicle-mounted device 10 does not necessarily need to send OBD information including vehicle speed information to the parking lot management device 20.

  It may be determined whether or not the registered vehicle that has been delivered is a return vehicle, and the above-described processing from step S4 to step S6 may be performed on the registered vehicle that has been delivered as a return vehicle.

  For this purpose, a return vehicle determination unit 27 is provided in the parking lot management device 20. The return vehicle determination unit 27 determines whether or not the registered vehicle that has left the vehicle is a return vehicle toward the parking lot by a determination method described later (see step S31, FIG. 5). The determination information is sent to the parking lot arrival time calculation unit 22. The parking lot arrival time calculation unit 22 calculates the parking lot arrival time for a registered vehicle that has been delivered as a return vehicle. In addition, the group division unit 23 performs group division for the registered vehicle that has been delivered as a return vehicle.

  As a result, the number of parking spaces reserved for the registered vehicles can be reduced, and more temporary vehicles can be permitted to park in vacant parking spaces when the registered vehicles are issued. Therefore, an empty parking space can be used more effectively.

  Here are some examples of how to determine whether a car is a return car. When the linear distance between the registered vehicle that has left and the parking lot is less than or less than a predetermined distance, the registered vehicle is determined to be a return vehicle. When the parking lot arrival time of the registered vehicle that has left the vehicle is less than or less than the predetermined parking lot arrival time, the registered vehicle is determined to be a return vehicle. If the straight line distance between the registered vehicle that has left and the parking lot decreases, it is determined that the vehicle is a return trip. If the straight line distance between the registered vehicle and the parking lot that has left is continuously reduced for a predetermined time or a predetermined distance, the vehicle is determined to be a return vehicle. Further, a return switch 15 may be provided in the registered vehicle. When the driver turns on the return switch 15, a return signal is sent to the parking lot management device 20. The return vehicle determination unit 27 determines whether or not a return signal is received. If the return signal is received, the return vehicle determination unit 27 determines that the registered vehicle that has issued the return signal is a return vehicle. Furthermore, these determination methods may be combined. For example, the linear distance between the registered vehicle that has left the car and the parking lot is less than or less than a predetermined distance, and the linear distance between the registered vehicle that has left the car and the parking lot continues for a predetermined time or a predetermined distance. If it decreases, it may be determined that the vehicle is a return trip.

  The in-vehicle device 10 may be provided with the IC card reader 16, and the parking lot management device 20 may be provided with the abnormality determination unit 28.

  The IC card reader 16 wirelessly communicates with an IC card 41 possessed by the driver 4 and acquires personal identification information of the driver 4 stored in the IC card 41. The personal identification information is information that can identify an individual such as a name, a number, and a password. The acquired personal identification information is stored in the storage unit 12. In addition, the transmission / reception unit 14 sends information about whether or not the personal identification information has been acquired to the parking lot management apparatus 20. Thereby, it can be confirmed whether the driver is seated.

  The abnormality determination unit 28 of the parking lot management apparatus 20 determines that an abnormality has occurred in the registered vehicle 1 when a change in GPS information and / or OBD information is detected in a state where personal identification information has not been acquired. Thereby, the abnormality of the registered vehicle 1 can be detected. Further, the parking lot management device 20 may be provided with a notification unit 215 for notifying a registered vehicle owner and / or a manager of the parking lot management system 100 that has been determined that an abnormality has occurred.

  In addition, the person who tries to remotely operate the registered vehicle 1 is authenticated by the IC card reader 16 using the personal identification information acquired from the IC card 41 possessed by the driver to determine whether or not the person has a legitimate access authority. The unit 19 may be provided in the registered vehicle 1. The driver 4 accesses the vehicle-mounted device 10 through the transmission / reception unit 14 by using a terminal device such as a mobile phone or when the operator operates the operation unit 210 of the parking lot management device 20, and the authentication unit 19. Get certified. If the authentication is successful, remote operation of the registered vehicle 1 is permitted. If the authentication fails, remote operation of the registered vehicle 1 is not permitted. By providing the authentication unit 19 in this way, it is possible to safely perform remote operations such as opening / closing the door and turning on / off the light.

  The space securing time may be an estimated time until a number of parking spaces equal to the number of registered vehicles included in the group multiplied by the approach rate newly open in the parking lot. That is, the space securing time may be calculated using the approach rate. Here, the approach rate is the ratio of the number of registered vehicles that have entered among all registered vehicles. For example, if there are nine registered vehicles out of all ten registered vehicles at 16:00 on a certain Monday, the approach rate is 9/10 = 0.9 (= 90%). The approach rate is estimated using the parking lot information received from the parking lot device 30 for a certain period (one day, one week, one month).

  The space securing time calculation unit 24 calculates the space securing time by multiplying the number of registered vehicles included in the group by the approach rate and dividing by the shipping rate. For example, if the shipping rate is 2.5 and the approach rate is 0.9, the number of registered vehicles C1 and C2 included in the group G1 within 0.5 hours is 2, so the space securing time for the group G1 is 2 X 0.9 / 2.5 = 0.72 hours.

In the above example, the group dividing unit 23 performs grouping of registered vehicles according to the parking lot arrival time, but may perform grouping according to the distance between the parking lot and the registered vehicle. Here, the distance is, for example, a linear distance or a road distance. In this case, the distance calculation unit 214 calculates the distance between each registered vehicle and the parking lot and sends it to the group dividing unit 23. The group dividing unit 23 groups registered vehicles based on the calculated distance.
These modifications can be combined as appropriate.

  When the parking lot management device 20 is realized by a computer, each part of the parking lot management device 20 is described by a program. By executing this program on a computer, the functions of the above-described units are realized on the computer.

  That is, when the CPU sequentially reads and executes each program, the parking lot arrival time calculation unit 22, the group division unit 23, the space securing time calculation unit 24, the determination unit 25, the transmission / reception unit 26, and the return path of the parking lot management device 20 Functions of the vehicle determination unit 27, the abnormality determination unit 28, the leaving rate calculation unit 29, the time unit 212, and the distance calculation unit 214 are realized. The storage unit 21 is realized by a storage unit such as a memory or a hard disk.

  The program describing the processing contents can be recorded on a computer-readable recording medium. The computer-readable recording medium may be any medium such as a magnetic recording device, an optical disk, a magneto-optical recording medium, or a semiconductor memory. Specifically, for example, the magnetic recording device may be a hard disk device or a flexible Discs, magnetic tapes, etc. as optical disks, DVD (Digital Versatile Disc), DVD-RAM (Random Access Memory), CD-ROM (Compact Disc Read Only Memory), CD-R (Recordable) / RW (ReWritable), etc. As the magneto-optical recording medium, MO (Magneto-Optical disc) or the like can be used, and as the semiconductor memory, EEP-ROM (Electronically Erasable and Programmable-Read Only Memory) or the like can be used.

  The program is distributed by selling, transferring, or lending a portable recording medium such as a DVD or CD-ROM in which the program is recorded. Furthermore, the program may be distributed by storing the program in a storage device of the server computer and transferring the program from the server computer to another computer via a network.

  As an execution form different from the above-described embodiment, the computer may read the program directly from the portable recording medium and execute processing according to the program. Each time is transferred, the processing according to the received program may be executed sequentially. Also, the program is not transferred from the server computer to the computer, and the above-described processing is executed by a so-called ASP (Application Service Provider) type service that realizes the processing function only by the execution instruction and result acquisition. It is good. Note that the program in this embodiment includes information that is used for processing by an electronic computer and that conforms to the program (data that is not a direct command to a computer but has a property that is based on computer processing).

  In this embodiment, the present apparatus is configured by executing a predetermined program on a computer. However, at least a part of these processing contents may be realized by hardware.

  In addition, the various processes described above are not only executed in time series according to the description, but may be executed in parallel or individually according to the processing capability of the apparatus that executes the processes or as necessary. For example, the process of step S1 and the process of step S2 can be performed in parallel.

  Needless to say, other modifications are possible without departing from the spirit of the present invention.
