[0009] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings.

[0010] (Overall composition) As shown in FIG. 1, a system 1 according to an embodiment of the present disclosure includes an information processing device 10 and one or more carsharing vehicles 20. The information processing device 10 and the carsharing vehicles 20 are configured to be able to communicate with each other via a network 30 including, for example, the Internet and a mobile communication network. The carsharing vehicles 20 are specific vehicles. Hereinafter, the carsharing vehicles 20 are simply referred to as "vehicles 20". For example, the information processing device 10 is a server device of a business operator that provides a carsharing service. The information processing device 10 may manage schedule information for the vehicles 20. The schedule information includes, for example, the start time, start location, end time, and end location of the vehicle 20 used by the user.

[0011] The information processing device 10 can transmit and receive information to and from an in-vehicle device 21 mounted on a vehicle 20. The in-vehicle device 21 is, for example, a navigation system. The information processing device 10 can provide information to a user of the vehicle 20 via the in-vehicle device 21. The user of the vehicle 20 includes a driver of the vehicle and / or a passenger in the vehicle.

[0012] The information processing device 10 may be configured to be capable of transmitting and receiving information to and from a first parking lot management device 50 that manages a parking lot 40. The parking lot 40 includes a general vehicle parking area 41 including a large number of parking spaces for general vehicles, and a first parking space 42 that is a dedicated parking space reserved for the vehicle 20. In this embodiment, the first parking space 42 is a parking space provided exclusively for the car-sharing vehicle 20. When applying to use the vehicle 20, the user of the vehicle 20 can select the first parking space 42 as the usage start position and / or usage end position of the vehicle 20.

[0013] In one embodiment, the parking lot 40 is surrounded, and a gate 43 is provided at an entrance that connects to a road outside the parking lot 40. The gate 43 controls the entry and exit of the vehicles 20 and general vehicles 45 to the parking lot 40. The gate 43 may be kept closed when the parking lot 40 is full, when the parking lot 40 is crowded, or when entry to the parking lot 40 is restricted.

[0014] A sensor 44 is installed near the gate 43 of the parking lot 40 to detect general vehicles 45 in front of the gate 43. The sensor 44 is, for example, a camera. The output of the sensor 44 is transmitted to the first parking lot management device 50. Based on the information acquired from the sensor 44, the first parking lot management device 50 can recognize whether it is difficult for the vehicle 20 to enter the parking lot 40. When general vehicles 45 waiting to enter the parking lot 40 are lined up in front of the gate 43, the first parking lot management device 50 can determine that it is difficult for the vehicle 20 to enter the parking lot 40.

[0015] When the first parking lot management device 50 determines that it is difficult for the vehicle 20 to enter the parking lot 40, it may transmit first information indicating that it is difficult to enter the parking lot 40 to the information processing device 10.

[0016] As another method, the manager of the parking lot may determine the congestion state of the parking lot. In this case, the information indicating the congestion state input by the manager of the parking lot to the first parking lot management device 50 may be transmitted to the information processing device 10 as the first information. In this case, the sensor 44 is not required.

[0017] When receiving the first information, the information processing device 10 can transmit, to the vehicle 20, second information indicating that the vehicle 20 can be parked in a spare second parking space 60 located on the periphery of the parking lot 40.

[0018] In one embodiment, the second parking space 60 may be part of another parking lot. A second parking lot management device 70 that manages the other parking lot may manage whether the second parking space 60 is available. The information processing device 10 may send an inquiry to the second parking lot management device 70 as to whether the second parking space 60 is available. When the information processing device 10 receives third information from the second parking lot management device 70 indicating that the vehicle 20 can be parked in the second parking space 60, it sends the second information to the vehicle 20.

[0019] In one embodiment, the information processing device 10 may be configured to transmit and receive information to and from a user terminal 80 carried by a user, instead of the in-vehicle device 21 of the vehicle 20. The user terminal 80 includes, for example, a smartphone, a tablet terminal, and the like.

[0020] (Configuration of information processing device) As shown in FIG. 2, the information processing device 10 includes a control unit 11, a storage unit 12, and a communication unit 13.

[0021] The control unit 11 includes at least one processor, at least one dedicated circuit, or a combination of these. The processor is a general-purpose processor such as a CPU (central processing unit), or a dedicated processor specialized for a specific process. The control unit 11 executes processes related to the operation of the information processing device 10 while controlling each unit of the information processing device 10. In the following, the processes executed by the control unit 11 may be described as being executed by the information processing device 10. The processes executed by the information processing device 10 can each be rephrased as processes executed by the control unit 11.

[0022] The storage unit 12 includes at least one semiconductor memory, at least one magnetic memory, at least one optical memory, or a combination of at least two of these. The storage unit 12 functions as, for example, a main storage device, an auxiliary storage device, or a cache memory. The storage unit 12 stores programs and data used in the operation of the information processing device 10, and data obtained by the operation of the information processing device 10. The information stored in the storage unit 12 may be updateable, for example, with information acquired from the network 30 via the communication unit 13.

[0023] The memory unit 12 may store and sequentially update information regarding the dispatch of each car sharing vehicle 20, information regarding dedicated parking spaces, and information regarding spare parking spaces. The information regarding dispatch may include scheduled information regarding the start location, start time, end location, and end time of use of the multiple vehicles 20. The information regarding dedicated parking spaces may include information regarding the location and reservation status of the parking spaces. The information regarding spare parking spaces may include information such as the location, available hours, and contact information of the parking spaces.

[0024] A dedicated parking space is a parking space that a user can specify as the start and end location of use when reserving a car sharing vehicle 20. A reserve parking space is a parking space that is prepared for cases such as when a dedicated parking space is not available. Reserve parking spaces include, for example, vacant lots that can be temporarily used by the car sharing operator, parking spaces managed by the car sharing operator, and parking spaces in parking lots separate from parking lot 40. Reserve parking spaces may include parking lots that are available depending on the time of day, such as company employee parking lots and daytime parking lots of stores that are open at night.

[0025] The communication unit 13 includes at least one external communication interface that connects to the network 30. The external communication interface may be either an interface for wired communication or wireless communication.

[0026] 2 of the present embodiment may further include an input unit and an output unit. That is, in addition to receiving (input) and transmitting (output) information via the communication unit 13, the information processing device 10 may input and output information by the input unit and the output unit.

[0027] The functions of the information processing device 10 are realized by executing a program according to the method of the present disclosure in a processor corresponding to the control unit 11. That is, the functions of the information processing device 10 are realized by software. The program causes a computer to execute the operations of the information processing device 10, thereby causing the computer to function as the information processing device 10. That is, the computer functions as the information processing device 10 by executing the operations of the information processing device 10 in accordance with the program.

[0028] In this embodiment, the program can be recorded in a computer-readable recording medium. The computer-readable recording medium includes a non-transitory computer-readable medium, such as a magnetic recording device, an optical disk, a magneto-optical recording medium, or a semiconductor memory.

[0029] (Configuration of the in-vehicle device) 3, the in-vehicle device 21 includes a control unit 22, a storage unit 23, a communication unit 24, a positioning unit 25, an input unit 26, and an output unit 27. The components of the in-vehicle device 21 may be at least partially distributed within the vehicle 20.

[0030] The control unit 22 includes at least one processor, at least one dedicated circuit, or a combination of these. The control unit 22 executes processes related to the operation of the in-vehicle device 21 while controlling each part of the in-vehicle device 21. In the following, the processes executed by the control unit 22 may be described as being executed by the in-vehicle device 21. The processes executed by the in-vehicle device 21 can be rephrased as processes executed by the control unit 22.

[0031] The storage unit 23 includes at least one semiconductor memory, at least one magnetic memory, at least one optical memory, or a combination of at least two of these. The storage unit 23 stores programs and data used in the operation of the in-vehicle device 21, and data obtained by the operation of the in-vehicle device 21. The information stored in the storage unit 23 may be updatable, for example, with information acquired from the network 30 via the communication unit 24.

[0032] The communication unit 24 includes at least one external communication interface that connects to the network 30. The communication unit 24 receives data used for the operation of the in-vehicle device 21, and transmits data obtained by the operation of the in-vehicle device 21 to the outside.

[0033] The positioning unit 25 includes one or more devices that acquire position information of the in-vehicle device 21. The position of the in-vehicle device 21 is the position of the vehicle 20. The positioning unit 25 includes, for example, a receiver compatible with a Global Positioning System (GPS), but is not limited thereto, and may include a receiver compatible with any satellite positioning system. The positioning unit 25 may acquire the position information of the in-vehicle device 21 constantly, or periodically or non-periodically.

[0034] The input unit 26 includes at least one input interface. The input interface is, for example, a physical key such as a keyboard, a capacitive key, a pointing device, or a touch screen integrally provided with a display. The input interface may also be, for example, a microphone that accepts voice input, or a camera that accepts image input. The input units 26 each accept an operation to input data used for the operation of the in-vehicle device 21. Instead of being provided in the in-vehicle device 21, the input unit 26 may be connected to the in-vehicle device 21 as an external input device.

[0035] The output unit 27 includes at least one output interface. The output interface is, for example, a display that outputs information as a video, or a speaker that outputs information as a sound. The display is, for example, an LCD or an organic EL display. The output unit 27 outputs data received via the network 30, or data obtained by the operation of the in-vehicle device 21. Each of the output units 27 may be connected to the in-vehicle device 21 as an external output device instead of being provided in the in-vehicle device 21.

[0036] As described above, the user terminal 80 may be used instead of the in-vehicle device 21. The user terminal 80 may include components similar to those of the in-vehicle device 21. However, even when the user terminal 80 is used, a positioning unit provided in the vehicle 20 may be used as the positioning unit. The vehicle 20 may be configured to transmit location information measured by a positioning unit 25 provided in the vehicle 20 to the information processing device 10.

[0037] (Information processing method executed by the system) The processes executed by the components of the system 1 will be described below with reference to the sequence diagram of FIG.

[0038] It is assumed that the user of the vehicle 20 has reserved the first parking space 42 in the parking lot 40 as a location to return the car-sharing vehicle 20 after completing use of the vehicle. The vehicle 20 is heading to the parking lot 40 to be returned.

[0039] The first parking lot management device 50 monitors the congestion situation around the gate 43 of the parking lot 40 based on the output from the sensor 44. If the first parking lot management device 50 does not detect congestion around the gate 43 of the parking lot 40, the vehicle 20 can enter the parking lot 40 and park in the first parking space 42. In this case, the process described below is not executed. Below, a case where the first parking lot management device 50 detects that the area around the gate 43 of the parking lot 40 is crowded (S101) will be described.

[0040] When detecting congestion at the entrance (S101), the first parking lot management device 50 transmits first information indicating that it is difficult to enter the parking lot 40 to the information processing device 10 (S102).

[0041] The first parking lot management device 50 may be configured to spontaneously transmit the first information to the information processing device 10. For example, the first parking lot management device 50 may be configured to transmit information on the congestion state near the gate 43 of the parking lot 40 acquired from the sensor 44 at a predetermined time interval to the information processing device 10. In this case, the information indicating that the entrance to the parking lot 40 is congested becomes the first information. Also, for example, the first parking lot management device 50 may transmit information notifying the information processing device 10 of the change in state every time the congestion state of the gate 43 of the parking lot 40 changes based on the output from the sensor 44. In this case, the information notifying that the state near the gate 43 of the parking lot 40 has changed from not congested to congested becomes the first information.

[0042] The first parking lot management device 50 may transmit information indicating a congestion state near the gate 43 of the parking lot 40 in response to an inquiry from the information processing device 10. The information processing device 10 may transmit an inquiry to the first parking lot management device 50 when a vehicle 20 that has reserved parking in the first parking space 42 approaches the parking lot 40 or when the parking reservation time of the vehicle 20 approaches. The information transmitted by the first parking lot management device 50 in response to an inquiry from the information processing device 10, indicating that the area near the gate 43 of the parking lot 40 is congested, becomes first information.

[0043] The information processing device 10 acquires information indicating that the vehicle 20 is approaching the parking lot 40 within a predetermined range from the in-vehicle device 21 of the vehicle 20 (S103). For example, the information processing device 10 may be configured to periodically receive the position information of the vehicle 20 acquired from the vehicle 20 by the positioning unit 25. The information processing device 10 may recognize that the vehicle 20 has entered a predetermined range from the position of the parking lot 40 from the position information of the vehicle 20. In another embodiment, the control unit 22 on the in-vehicle device 21 side may calculate the distance to the parking lot 40, and when the distance becomes equal to or less than the predetermined distance, information indicating that the vehicle 20 is approaching the parking lot 40 may be transmitted to the information processing device 10. The predetermined range may be, for example, a range expressed by distance, such as within 5 km from the position of the parking lot 40. Alternatively, the predetermined range may be set according to an expected time it takes for the vehicle 20 to reach the parking lot 40, taking into consideration the congestion status of roads around the parking lot 40, the speed limit, and the like.

[0044] Either S102 or S103 may be performed first. For example, when the information processing device 10 acquires information from the in-vehicle device 21 in S103, the information processing device 10 may request information on the congestion state of the gate 43 of the parking lot 40 from the first parking lot management device 50 and receive the first information. When the information processing device 10 receives the first information from the first parking lot management device 50 in S102 and acquires information indicating that the vehicle 20 is approaching the parking lot 40 in S103, the information processing device 10 determines that a spare second parking space 60 is necessary. Instead of acquiring the information in S103, the information processing device 10 may determine that the second parking space 60 is necessary when the time until the reserved time for the user of the vehicle 20 to return the vehicle 20 to the first parking space 42 falls within a predetermined time. In this way, it is possible to guide the user to the parking space at an appropriate timing.

[0045] When the information processing device 10 determines that it is necessary to prepare a second parking space 60, it searches for a spare parking space (S104). The information processing device 10 stores information on a plurality of spare parking spaces in the storage unit 12. The information on the spare parking space includes information such as the location information of the spare parking space, the available time period, and the conditions of use. The conditions of use include, for example, the usage fee for the parking space if it is within another parking lot, and whether or not confirmation of availability is required before use.

[0046] The information processing device 10 selects a second parking space 60 that is relatively close to the parking lot 40. If the second parking space 60 is available unconditionally, the following steps S105 to S107 are unnecessary. However, if there are usage conditions for the second parking space 60, the information processing device 10 needs to check in advance whether the second parking space 60 can be used. For example, if the second parking space 60 is located in another parking lot, the information processing device 10 inquires of the second parking lot management device 70 that manages the other parking lot whether the second parking space 60 can be used (S105).

[0047] When the second parking lot management device 70 receives an inquiry about the availability of the second parking space 60, it determines whether the second parking space 60 is available (S106). For example, when the second parking space 60 is rented to another person, the second parking lot management device 70 may request the user of the second parking space 60 to vacate the parking space, or may secure a vacant parking space to replace the second parking space 60. Some of the processes executed by the second parking lot management device 70 may be executed by a person using the second parking lot management device 70.

[0048] When the second parking space 60 becomes available for use, the second parking lot management device 70 transmits third information notifying the information processing device 10 that the second parking space 60 is available for use (S107). Upon receiving the third information, the information processing device 10 transmits second information, which is information notifying the in-vehicle device 21 that the second parking space 60 is available for use (S108). The second information may include location information of the second parking space 60. In this way, a vacant space in another parking lot can be effectively used as the second parking space 60.

[0049] When receiving the second information, the in-vehicle device 21 may display the position information and route information of the second parking space 60 on a display, which is one of the output units 27 (S109). The in-vehicle device 21 may request the user to input whether or not to use the second parking space 60, and transmit the result to the information processing device 10. However, the in-vehicle device 21 may not need to request such input from the user.

[0050] The user can select either the first parking space 42 or the second parking space 60 and park the vehicle 20. When parking of the vehicle 20 is completed, the vehicle 20 transmits fourth information indicating that parking has been completed to the information processing device 10 (S110). The information processing device 10 can determine whether the user has selected the first parking space 42 or the second parking space 60 from the position information of the vehicle 20.

[0051] When the fourth information is received, the information processing device 10 recognizes that the vehicle 20 has been returned and the returned parking space, and ends the use of the car share (S111). The information processing device 10 recognizes that the use of the service has been properly ended, even if the place where the vehicle 20 has been returned is the second parking space 60. If necessary, the information processing device 10 may generate an instruction to move the vehicle 20 parked in the second parking space 60 to the first parking space 42. In this case, the vehicle 20 is moved to the first parking space 42 by the worker who received the movement instruction, and then made available for use by the next user.

[0052] In another embodiment, unlike the above, the vehicle 20 is parked in the second parking space 60. The information processing device 10 may inform the next user of the vehicle 20 of the location of the second parking space 60 as the location from which the user will start using the vehicle 20. In this way, there is no need for human intervention to move the vehicle 20, and the car sharing service can be provided efficiently.

[0053] (Processing performed by information processing device) Next, the process executed by the control unit 11 of the information processing device 10 will be described with reference to Fig. 5. Since each step shown in Fig. 5 partially overlaps with that explained using Fig. 4, the overlapping parts will be explained in a simplified manner.

[0054] First, while the user is using the vehicle 20, the control unit 11 monitors the operation of the vehicle 20 (S201).

[0055] The control unit 11 determines whether the vehicle 20 is within a predetermined range from the parking lot 40 based on the information received from the vehicle 20 (S202). If it is determined in S202 that the vehicle 20 is within the predetermined range (S202: Yes), the control unit 11 proceeds to processing of S204. If the vehicle 20 is not within the predetermined range from the parking lot 40 (S202: No), the control unit 11 proceeds to processing of S203.

[0056] In S203, the information processing device 10 determines whether the time from the reserved time when the vehicle 20 arrives at the first parking space 42 to the scheduled return time of the vehicle 20 is within a predetermined time (S203). If it is determined in S203 that it is within the predetermined time (S202: Yes), the control unit 11 proceeds to the process of S204. If the scheduled return time of the vehicle 20 is not within the predetermined time (S202: No), the control unit 11 returns to the process of S202.

[0057] 5, the control unit 11 proceeds to S204 when either of the conditions is satisfied, that is, the distance from the vehicle 20 to the parking lot 40 is within a predetermined range, or the time until the scheduled arrival time of the vehicle 20 at the first parking space 42 is within a predetermined time. The control unit 11 determines whether or not it is difficult for the vehicle 20 to enter the parking lot 40 based on information obtained from the first parking lot management device 50 (S204).

[0058] If it is not difficult to enter the parking lot 40 in S204 (S204: No), the control unit 11 guides the vehicle 20 to the first parking space 42 as scheduled (S205). The control unit 11 does not need to transmit any special information to the in-vehicle device 21.

[0059] In S204, if it is difficult to enter the parking lot 40 (S204: Yes), the control unit 11 searches for a second parking space candidate from among the spare parking spaces stored in the memory unit 12 (S206).

[0060] The control unit 11 determines whether or not there is an available spare parking space near the parking lot 40 (S207). The control unit 11 may search for a spare parking space within a predetermined distance range from the parking lot 40 as a candidate for the second parking space. The predetermined distance is, for example, but is not limited to, 100 m, 300 m, 500 m, or 1 km.

[0061] If there is a candidate for the second parking space (S208: Yes), the control unit 11 proceeds to S208. If the second parking space is unconditionally available, the control unit 11 may proceed directly from S207 to S210 without executing S208 and S209. If there is no candidate for the second parking space (S208: No), the control unit 11 proceeds to S205 and provides guidance to the first parking space.

[0062] In S208, the control unit 11 inquires of the second parking lot management device 70 that manages the second parking space candidate whether the second parking space candidate may be used as the second parking space 60 (S208).

[0063] When the control unit 11 receives a response indicating that the second parking space candidate can be used as the second parking space 60 (S209: Yes), the control unit 11 proceeds to S210. When the control unit 11 receives a response indicating that the second parking space candidate cannot be used as the second parking space 60 (S209: No), the control unit 11 returns to S206 and repeats the search for other available spare parking spaces.

[0064] In S210, the control unit 11 transmits information guiding the second parking space 60 to the in-vehicle device 21 of the vehicle 20 (S210).

[0065] When the user parks the vehicle 20 in the first parking space 42 or the second parking space 60, the control unit 11 recognizes that use of the vehicle 20 has ended by receiving parking completion information from the in-vehicle device 21 or judging from the position information of the vehicle 20 (S211).

[0066] As described above, according to this embodiment, the information processing device 10 can quickly provide the second parking space 60 to the user of the vehicle 20 when it is difficult to enter the parking lot 40.

[0067] The present invention is not limited to the above-described embodiment, and many variations and modifications are possible. For example, the functions included in each means, step, etc. can be rearranged so as not to cause logical inconsistencies, and multiple means or steps can be combined into one or divided.

[0068] For example, in the above embodiment, a car sharing vehicle 20 is described as an example of the specific vehicle. However, the specific vehicle is not limited to this. The specific vehicle may include various vehicles. For example, the specific vehicle may be a rental vehicle that is rented out for a fee. Also, for example, the specific vehicle may be an electric vehicle, and the first parking space may be a reservable charging space for the electric vehicle. In that case, if it is difficult to arrive at the reserved charging space in the parking lot, the information processing device can guide the specific vehicle to a spare charging space. Furthermore, the specific vehicle may be a vehicle that wishes to receive a car wash service, and the first parking space may be a parking space for the car wash service. [Explanation of symbols]
