[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, like components are designated by like reference numerals.
[0019] First Embodiment First, a first embodiment of the present invention will be described with reference to Fig. 1 to Fig. 8. Fig. 1 is a schematic configuration diagram of a vehicle transport system 100 according to the first embodiment of the present invention. As shown in Fig. 1, the vehicle transport system 100 includes a plurality of vehicle transport devices 1 and a server 90. The server 90 is capable of communicating with each of the plurality of vehicle transport devices 1 via a wireless base station 80 such as a macrocell or a small cell, and a communication network 81 such as the Internet network or a carrier network.
[0020] The vehicle conveyance system 100 provides a vehicle conveyance service using the vehicle conveyance device 1. Specifically, the vehicle conveyance system 100 conveys a user's vehicle using the vehicle conveyance device 1 in response to a conveyance request from the user.
[0021] The vehicle transporter 1 transports a vehicle by supporting the vehicle and traveling on a road surface. In particular, in this embodiment, the vehicle transporter 1 transports the vehicle by autonomous traveling. That is, the vehicle transporter 1 is a self-propelled vehicle transporter.
[0022] The configuration of the vehicle transporter 1 will be described below. Fig. 2A is a side view of the vehicle transporter 1 when the vehicle transporter 1 is not supporting a vehicle, and Fig. 2B is a side view of the vehicle transporter 1 when the vehicle transporter 1 is supporting a vehicle. Fig. 3A is a top view of the vehicle transporter 1 when the vehicle transporter 1 is not supporting a vehicle, and Fig. 3B is a top view of the vehicle transporter 1 when the vehicle transporter 1 is supporting a vehicle. As shown in Figs. 2A to 3B, the vehicle transporter 1 has a main body 2 and a cart 3 extending from the main body 2.
[0023] The main body 2 has a LIDAR (Laser Imaging Detection And Ranging) 21, two motors 22, and two front tires 23. The LIDAR 21 detects peripheral information (obstacles, road surface information, etc.) of the vehicle transporter 1 for autonomous travel of the vehicle transporter 1. The two motors 22 are each driven by power supplied from a battery (not shown) housed in the main body 2, and rotate the two front tires 23. In other words, the two motors 22 output power for travel of the vehicle transporter 1 and function as a drive device for the vehicle transporter 1.
[0024] The cart unit 3 supports a vehicle to be transported, i.e., a vehicle transported by the vehicle transport device 1. Specifically, the cart unit 3 slides into the space between the underside of the vehicle and the road surface from the front or rear of the vehicle, and supports the vehicle by lifting up the tires of the vehicle.
[0025] The dolly unit 3 has a telescopic arm 31, a front support unit 32, a rear support unit 33, and a lift unit 34. The telescopic arm 31 extends from the main body unit 2, and the front support unit 32, the rear support unit 33, and the lift unit 34 are attached to the telescopic arm 31. The front support unit 32 and the rear support unit 33 are arranged apart from each other in the extension direction (longitudinal direction) of the telescopic arm 31, and the lift unit 34 is arranged at the same position as the rear support unit 33 in the extension direction of the telescopic arm 31. The front support unit 32 supports one of the front and rear tires of the vehicle to be transported, and the rear support unit 33 supports the other of the front and rear tires of the vehicle to be transported.
[0026] The telescopic arm 31 contributes to the strength of the cart unit 3 and adjusts the distance between the front support unit 32 and the rear support unit 33. For example, the telescopic arm 31 is driven by a linear actuator and is telescopic so as to change the distance between the front support unit 32 and the rear support unit 33. The telescopic arm 31 telescopically extends and retracts between a stored position where the distance between the front support unit 32 and the rear support unit 33 is the shortest, and an extended position where the distance between the front support unit 32 and the rear support unit 33 is the longest.
[0027] The front support section 32 has a pair of fixed clamp arms 321, a pair of first movable clamp arms 322, and a pair of first linear actuators 323. The pair of fixed clamp arms 321 and the pair of first movable clamp arms 322 are arranged apart from each other in the extending direction of the telescopic arm 31. The pair of fixed clamp arms 321 are arranged closer to the main body section 2 than the pair of first movable clamp arms 322, and extend perpendicular to the telescopic arm 31. Meanwhile, the pair of first movable clamp arms 322 are connected to the pair of first linear actuators 323, and are rotated by the reciprocating motion of the pair of first linear actuators 323. In this embodiment, the pair of first movable clamp arms 322 rotate 90 degrees between a closed position (FIG. 3A) parallel to the telescopic arm 31 and an open position (FIG. 3B) perpendicular to the telescopic arm 31.
[0028] The rear support section 33 has a pair of second movable clamp arms 331, a pair of second linear actuators 332, a pair of third movable clamp arms 333, and a pair of third linear actuators 334. The pair of second movable clamp arms 331 and the pair of third movable clamp arms 333 are disposed apart from each other in the extending direction of the telescopic arm 31. The pair of second movable clamp arms 331 are connected to the pair of second linear actuators 332 and are rotated by the reciprocating motion of the pair of second linear actuators 332. In this embodiment, the pair of second movable clamp arms 331 rotate 90 degrees between a closed position (FIG. 3A) parallel to the telescopic arm 31 and an open position (FIG. 3B) perpendicular to the telescopic arm 31. On the other hand, the pair of third movable clamp arms 333 are connected to the pair of third linear actuators 334 and are rotated by the reciprocating motion of the pair of third linear actuators 334. In this embodiment, the pair of third movable clamp arms 333 rotate 90 degrees between a closed position (FIG. 3A) parallel to the telescopic arm 31 and an open position (FIG. 3B) perpendicular to the telescopic arm 31.
[0029] The lift unit 34 has a rotating arm 341 and four rear tires 342 attached to the tip of the rotating arm 341. The rotating arm 341 is driven by, for example, a motor, and rotates relative to the telescopic arm 31 with the rear tires 342 in contact with the road surface. The rotating arm 341 rotates between a rest position (FIG. 2A) parallel to the telescopic arm 31 and a lift position (FIG. 2B) oblique to the telescopic arm 31 so that the distance between the telescopic arm 31 and the road surface changes.
[0030] When the vehicle transport device 1 is not supporting a vehicle, it is in the state shown in Figures 2A and 3A. That is, the telescopic arm 31 is in the stored position, the first movable clamp arm 322, the second movable clamp arm 331 and the third movable clamp arm 333 are in the closed position, and the rotating arm 341 is in the stationary position. On the other hand, when the vehicle transport device 1 is supporting a vehicle, it is in the state shown in Figures 2B and 3B. That is, the telescopic arm 31 is in the extended position, the first movable clamp arm 322, the second movable clamp arm 331 and the third movable clamp arm 333 are in the open position, and the rotating arm 341 is in the lift position.
[0031] The operation of the vehicle transport device 1 when the vehicle transport device 1 transports a vehicle will be described below. First, the vehicle transport device 1 approaches the vehicle so that the dolly unit 3 passes between the left and right front tires from the front of the vehicle and is inserted into the space between the vehicle and the road surface. At this time, the vehicle transport device 1 moves relative to the vehicle so that the telescopic arm 31 is positioned on the center line of the vehicle width. When the rear support unit 33 passes the front tires and is positioned between the front tires and the rear tires, the second movable clamp arm 331 of the rear support unit 33 is rotated from the closed position to the open position. Then, the vehicle transport device 1 moves rearward of the vehicle until the fixed clamp arm 321 of the front support unit 32 abuts against the front tire of the vehicle.
[0032] When the fixed clamp arm 321 abuts against the front tire of the vehicle, the telescopic arm 31 is extended until the second movable clamp arm 331 in the open position abuts against the rear tire of the vehicle. Thereafter, with the fixed clamp arm 321 abutting against the front tire of the vehicle and the second movable clamp arm 331 abutting against the rear tire of the vehicle, the first movable clamp arm 322 of the front support part 32 and the third movable clamp arm 333 of the rear support part 33 are rotated from the closed position to the open position. As a result, the front tire of the vehicle is clamped by the fixed clamp arm 321 and the first movable clamp arm 322, and the rear tire of the vehicle is clamped by the second movable clamp arm 331 and the third movable clamp arm 333.
[0033] With all the tires of the vehicle clamped, the rotating arm 341 of the lift unit 34 is rotated from the rest position to the lift position. As a result, the tires of the vehicle leave the road surface, and the vehicle is supported by the cart unit 3. With the cart unit 3 supporting the vehicle, the vehicle transport device 1 moves to a target position (e.g., a parking space) by autonomous driving. At the target position, the vehicle is removed from the vehicle transport device 1 by reversing the procedure described above.
[0034] In the above example, the bogie unit 3 is inserted under the vehicle from the front of the vehicle, but the bogie unit 3 may be inserted under the vehicle from the rear of the vehicle. In this case, the rear tires of the vehicle are clamped by the fixed clamp arm 321 and the first movable clamp arm 322, and the front tires of the vehicle are clamped by the second movable clamp arm 331 and the third movable clamp arm 333.
[0035] 4 is a diagram that shows a schematic view of a part of the configuration of the vehicle transport apparatus 1. As shown in FIG.
[0036] The controller 4 is, for example, a general-purpose computer, and performs various controls of the vehicle transport apparatus 1. The controller 4 is housed in the main body 2, and the sensor 5, the actuator 6, and the communication device 7 are electrically connected to the controller 4. The controller 4 is an example of a control device for the vehicle transport apparatus 1.
[0037] 4, the controller 4 includes a memory 41 and a processor 42. The memory 41 and the processor 42 are connected to each other via a signal line.
[0038] The memory 41 includes, for example, a volatile semiconductor memory (for example, a RAM) and a non-volatile semiconductor memory (for example, a ROM). The memory 41 stores computer programs executed by the processor 42, various data used when the processor 42 executes various processes, and the like.
[0039] The processor 42 has one or more central processing units (CPUs) and their peripheral circuits, and executes various processes. The processor 42 may further include an arithmetic circuit such as a logical arithmetic unit or a numerical arithmetic unit.
[0040] The sensor 5 includes a surrounding information detection device including the above-mentioned LIDAR 21, and a GNSS receiver that detects the current position of the vehicle transport apparatus 1. The output of the sensor 5 is transmitted to the controller 4, and the controller 4 controls the autonomous traveling of the vehicle transport apparatus 1 based on the output of the sensor 5. Note that the number and arrangement of the LIDAR 21 may be different from those described above. Furthermore, the vehicle transport apparatus 1 may include a LIDAR, a millimeter wave radar, a camera, or an ultrasonic sensor (sonar), or any combination of these, as the surrounding information detection device.
[0041] The actuator 6 includes the motor 22, a linear actuator for extending and retracting the extension arm 31, a first linear actuator 323, a second linear actuator 332, a third linear actuator 334, and a motor for rotating the rotating arm 341. The controller 4 operates the actuator 6 based on the output of the sensor 5 and the like.
[0042] The communication device 7 enables communication between the vehicle transport apparatus 1 and the server 90. For example, the communication device 7 is a wide-area communication device that can access a wireless base station 80. The communication device 7 may be a WiFi module that can access a WiFi (registered trademark) router. In this case, the vehicle transport apparatus 1 communicates with the server 90 without going through the wireless base station 80.
[0043] 5 is a diagram showing a schematic configuration of a server 90. The server 90 includes a communication interface 91, a storage device 92, a memory 93, and a processor 94. The communication interface 91, the storage device 92, and the memory 93 are connected to the processor 94 via signal lines. The server 90 may further include input devices such as a keyboard and a mouse, and an output device such as a display. The server 90 may also be composed of multiple computers.
[0044] The communication interface 91 has an interface circuit for connecting the server 90 to the communication network 81. The server 90 communicates with each of the multiple vehicle transport devices 1 via the communication network 81. The communication interface 91 is an example of a communication unit of the server 90.
[0045] The storage device 92 includes, for example, a hard disk drive (HDD), a solid state drive (SDD), or an optical recording medium and an access device therefor. The storage device 92 stores various data, for example, information on the vehicle transport device 1 (identification information, position information, etc.), computer programs for the processor 94 to execute various processes, etc. The storage device 92 is an example of a storage unit of the server 90.
[0046] The memory 93 includes a non-volatile semiconductor memory (e.g., a RAM). The memory 93 temporarily stores various data and the like used when various processes are executed by the processor 94. The memory 93 is another example of a storage unit of the server 90.
[0047] The processor 94 has one or more CPUs and their peripheral circuits, and executes various processes. The processor 94 may further include other arithmetic circuits, such as a logic arithmetic unit, a numerical arithmetic unit, or a graphic processing unit.
[0048] The server 90 manages a plurality of vehicle transport devices 1 to provide a vehicle transport service to a user. That is, the server 90 is an example of a vehicle transport management device that manages a plurality of vehicle transport devices 1. In response to a transport request from a user, the server 90 dispatches the vehicle transport device 1 for transporting the vehicle to the vehicle's stop location.
[0049] FIG. 6 is a diagram showing an example of a situation in which a vehicle transport service is provided. In the example of FIG. 6, a vehicle transport service is provided in a parking lot 500, and the vehicle 400 is parked by a vehicle transport device 1 instead of a driver of the vehicle 400. The parking lot 500 is, for example, a parking lot of an airport, a station, an amusement park, a hospital, a stadium, a shopping center, or the like. The parking lot 500 has a boarding and disembarking place 510 where the occupant of the vehicle 400 gets on and off the vehicle 400, and a plurality of parking spaces 520 in which the vehicle 400 is parked. The boarding and disembarking place 510 is provided near the entrance of the parking lot 500, and has a plurality of (four in the example of FIG. 6) storage spaces 511. Each of the plurality of storage spaces 511 may be an open space or a space such as a garage that can be opened and closed.
[0050] In the parking lot 500, vehicle transportation is carried out by a plurality of (four in the example of FIG. 6) vehicle transport devices 1. The server 90 is disposed in a parking management center 530 that manages the parking lot 500, and manages the plurality of vehicle transport devices 1.
[0051] An occupant of vehicle 400 who uses the vehicle transport service in parking lot 500 parks vehicle 400 at a boarding / disembarking location 510 in parking lot 500, specifically, at an empty storage space 511 not occupied by another vehicle. Thereafter, the occupant of vehicle 400 disembarks from vehicle 400 and inputs request information (vehicle identification information (such as license plate information), desired pick-up time of vehicle 400, etc.) to an information reading device (not shown) provided at boarding / disembarking location 510. Note that the occupant of vehicle 400 may input the request information to the information reading device via short-distance wireless communication between a mobile terminal (such as a smartphone or tablet terminal) and the information reading device, a QR code (registered trademark) displayed on the mobile terminal, or the like.
[0052] When the request information is input to the information reading device, a warehousing request notice including the request information is transmitted from the information reading device to the server 90 via the communication network 81 or the like. In response to the warehousing request notice, the server 90 transmits a transport instruction to one of the vehicle transport devices 1 among the plurality of vehicle transport devices 1. The vehicle transport device 1 that receives the transport instruction from the server 90 moves to the boarding and disembarking location 510 and places the unmanned vehicle 400 on the vehicle transport device 1 at the boarding and disembarking location 510. Next, the vehicle transport device 1 transports the vehicle 400 to an empty parking space 520 and unloads the vehicle 400 from the vehicle transport device 1 so that the vehicle 400 fits into the parking space 520. As a result, the transport of the vehicle 400 is completed, and the vehicle 400 is parked in the parking lot 500. The warehousing request notice may be transmitted to the server 90 from a mobile terminal or the like of a user (a passenger of the vehicle 400).
[0053] On the other hand, when the desired pick-up time of the vehicle 400 parked in the parking lot 500 approaches, the server 90 transmits a transportation instruction to one of the vehicle transport devices 1 in order to have the vehicle 400 leave the parking lot 500. The vehicle transport device 1 that has received the transportation instruction from the server 90 moves to the parking space 520 in which the vehicle 400 is parked, and places the unmanned vehicle 400 on the vehicle transport device 1 in the parking space 520. Next, the vehicle transport device 1 transports the vehicle 400 to the boarding and disembarking location 510, and unloads the vehicle 400 from the vehicle transport device 1 so that the vehicle 400 fits into an empty storage space 511. As a result, the transportation of the vehicle 400 is completed, and the occupant of the vehicle 400 picks up the vehicle 400 at the boarding and disembarking location 510.
[0054] According to the vehicle transport service as described above, since it is not necessary to secure a space for the vehicle occupants to get in and out of the parking space, many parking spaces can be provided within a given area. In addition, since the vehicle occupants are not required to carry out troublesome parking tasks such as searching for a parking space and maneuvering the vehicle to park, the convenience of the parking lot can be improved, and the use of the parking lot can be promoted.
[0055] However, since it is expected that various types of vehicles will use the parking lot, the vehicle transport device 1 needs to transport various types of vehicles. The vehicle transport device 1 can transport vehicles with different wheelbases by extending and retracting the telescopic arm 31 to change the distance between the front support part 32 and the rear support part 33. However, there is a limit to the length of the wheelbase that can be accommodated by extending and retracting the telescopic arm 31. In addition, when a heavy vehicle is transported, the vehicle transport device 1 may not be able to lift the vehicle, or the transport speed of the vehicle may be significantly reduced. Therefore, when only one type of vehicle transport device 1 is used for various types of vehicles, it is difficult to realize smooth vehicle transport.
[0056] Therefore, in this embodiment, multiple types of vehicle transport devices 1 having different transport characteristics are prepared. That is, the vehicle transport system 100 includes multiple types of vehicle transport devices 1, and provides vehicle transport services using multiple types of vehicle transport devices 1. For example, the different transport characteristics include the rated output of the drive device (specifically, the motor 22), the rigidity (e.g., load capacity) of the cart unit 3, the length of the available wheelbase, the force to lift the vehicle, and the number of tires. When the rigidity of the cart unit 3 is different, for example, the material, thickness, etc. of the cart unit 3 (particularly the telescopic arm 31) are changed between the multiple types of vehicle transport devices 1. When the length of the available wheelbase is different, for example, the length of the telescopic arm 31 at the storage position, the telescopic distance of the telescopic arm 31, etc. are changed between the multiple types of vehicle transport devices 1. When the force to lift the vehicle is different, for example, the rated output, etc. of the motor driving the rotating arm 341 of the lift unit 34 are changed between the multiple vehicle transport devices 1.
[0057] The appropriate type of vehicle transport device 1 varies depending on the characteristics of the vehicle to be transported. For this reason, in this embodiment, a specific type of vehicle transport device 1 appropriate for transporting the vehicle to be transported is selected based on vehicle information about the vehicle to be transported. This makes it possible to realize smooth vehicle transport even when various types of vehicles are transported using the vehicle transport device 1. Such processing is performed by a server 90 that manages multiple types of vehicle transport devices 1, as described below.
[0058] 7 is a functional block diagram of the processor 94 of the server 90. In this embodiment, the processor 94 has a vehicle information acquisition unit 95 and a transportation plan creation unit 96. The vehicle information acquisition unit 95 and the transportation plan creation unit 96 are functional modules that are realized by the processor 94 of the server 90 executing a computer program stored in the memory 93 of the server 90. Note that these functional modules may each be realized by a dedicated arithmetic circuit provided in the processor 94.
[0059] The vehicle information acquisition unit 95 acquires vehicle information related to the vehicle to be transported. The transportation plan creation unit 96 creates a transportation plan for the vehicle to be transported. For example, the transportation plan creation unit 96 selects a specific type of vehicle transport device 1 from among multiple types of vehicle transport devices 1 as a vehicle transport device that transports the vehicle to be transported.
[0060] Hereinafter, a control flow when a vehicle is transported by the vehicle transport device 1 will be described in detail with reference to Fig. 8. Fig. 8 is a flowchart showing a control routine for vehicle transport processing in the first embodiment. This control routine is executed by the processor 94 of the server 90 according to a computer program stored in the memory 93 of the server 90.
[0061] First, in step S101, the vehicle information acquisition unit 95 determines whether vehicle transportation has been requested. For example, the vehicle information acquisition unit 95 determines that vehicle transportation has been requested when a warehousing request notification is transmitted from the information reading device to the server 90, or when the time from the current time to the desired pick-up time of the parked vehicle reaches a predetermined time. If it is determined in step S101 that vehicle transportation has not been requested, this control routine ends. On the other hand, if it is determined in step S101 that vehicle transportation has been requested, this control routine proceeds to step S102.
[0062] In step S102, the vehicle information acquisition unit 95 acquires vehicle information (hereinafter simply referred to as "vehicle information") regarding the vehicle to be transported. For example, when a vehicle is transported for storage, the vehicle information acquisition unit 95 acquires the vehicle information based on images generated by cameras installed around the vehicle to be transported. In the example shown in FIG. 6, cameras 512 are provided at each of the four corners of the storage space 511 of the boarding and disembarking location 510, and the output of the cameras 512 is transmitted to the server 90 via the communication network 81 or the like. That is, the vehicle information acquisition unit 95 acquires the vehicle information based on the images generated by the cameras 512.
[0063] The vehicle information is, for example, information indicating the size of the vehicle to be transported. As a specific example, the vehicle information is the vehicle name, model, or size type information (for example, large vehicle, medium-sized vehicle, normal vehicle, etc.) of the vehicle, or includes at least one of the vehicle width, vehicle length, tire inch size, and wheelbase of the vehicle. The vehicle information is acquired, for example, using a classifier that has been trained in advance to output predetermined vehicle information from an image generated by the camera 512. Examples of such classifiers include machine learning models such as neural networks, support vector machines, and random forests.
[0064] A weight sensor (not shown) may be provided in each of the storage spaces 511, and the weight of the vehicle detected by the weight sensor may be transmitted as vehicle information to the server 90. Information previously input to a terminal device such as an HMI (Human Machine Interface) of the vehicle or a mobile terminal of the user, or information directly input to an information reading device provided at the boarding and disembarking location 510 may be transmitted to the server 90 as vehicle information.
[0065] In addition, the vehicle information acquired when the vehicle enters the garage is stored in the storage device 92 or memory 93 of the server 90, and is read out by the vehicle information acquisition unit 95 when the vehicle is transported to leave the garage. In other words, when the vehicle is transported to leave the garage, the vehicle information acquisition unit 95 acquires the vehicle information from the storage device 92 or memory 93 of the server 90.
[0066] Next, in step S103, the transportation plan creation unit 96 selects a specific type of vehicle transporting device 1 from among multiple types of vehicle transporting devices 1 as a vehicle transporting device that transports the vehicle to be transported, based on the vehicle information acquired by the vehicle information acquisition unit 95. For example, a correspondence relationship between the vehicle information and the type of vehicle transporting device 1 is determined in advance and stored as a database in the storage device 92 or memory 93 of the server 90. In this case, the transportation plan creation unit 96 selects a specific type of vehicle transporting device 1 from among multiple types of vehicle transporting devices 1 based on the vehicle information in accordance with the correspondence relationship described in the database.
[0067] Next, in step S104, the transportation plan creation unit 96 determines the destination of the vehicle to be transported. When the vehicle is transported to leave the vehicle depot, the vehicle information acquisition unit 95 selects an empty storage space 511 at the boarding and disembarking location 510 as the destination of the vehicle. Whether or not the storage space 511 is empty is determined based on an image generated by, for example, a camera 512. This determination may be made based on the output of a vehicle detection device such as a metal detector provided in the storage space 511.
[0068] On the other hand, when a vehicle is transported for entering the parking space, the transportation plan creation unit 96 selects a vacant parking space 520 as the destination of the vehicle. Whether the parking space 520 is vacant is determined based on, for example, past entry and exit information. This determination may be made based on the output of a vehicle detection device such as a metal detector or a camera provided in the parking space 520.
[0069] In addition, in order to accommodate parking of vehicles of different sizes, multiple types of parking spaces of different sizes may be provided in the parking lot 500. In this case, the transportation plan creation unit 96 selects a specific type of parking space from the multiple types of parking spaces as a parking space to which the vehicle to be transported is transported based on the vehicle information. This makes it possible to suppress a mismatch between the vehicle to be transported and the parking space, and thus to promote smooth vehicle transportation.
[0070] Next, in step S105, the transportation plan creation unit 96 transmits a transportation instruction to the specific type of vehicle transportation device 1 selected in step S103. The transportation instruction includes the current position of the vehicle to be transported (e.g., the identification number of the storage space 511 or the parking space 520), information on the transportation destination (e.g., the identification number of the storage space 511 or the parking space 520), etc. After step S105, this control routine ends.
[0071] Second Embodiment The vehicle transport system and vehicle transport management device according to the second embodiment are basically the same as those according to the first embodiment, except for the points described below. Therefore, the second embodiment of the present invention will be described below, focusing on the differences from the first embodiment.
[0072] In the first embodiment, the multiple types of vehicle transport devices 1 are placed in a specific facility such as a parking lot, and transport vehicles from a predetermined boarding and disembarking location within the facility. Meanwhile, in the second embodiment, the multiple types of vehicle transport devices 1 are placed within a predetermined target area, and transport vehicles from any location within the target area. The target area is an area surrounded by a predetermined boundary, and is, for example, a smart city, which is defined as "a sustainable city or district where management (planning, development, management, operation, etc.) is carried out while utilizing new technologies such as ICT to address various problems facing the city, and overall optimization is achieved."
[0073] When transporting a vehicle from an arbitrary location, it is not possible to obtain vehicle information of the vehicle to be transported using equipment installed in advance. On the other hand, in a target area such as a smart city, data is collected from a large number of cameras placed in the target area to realize a safe and efficient urban life.
[0074] Therefore, in the second embodiment, the vehicle information acquisition unit 95 acquires the position information of the vehicle to be transported, and identifies the cameras installed around the vehicle to be transported based on the position information. Then, the vehicle information acquisition unit 95 acquires the vehicle information of the vehicle to be transported based on the image generated by the camera. In this way, even when the vehicle is transported from an arbitrary location, it is possible to dispatch a vehicle transport device 1 of an appropriate type for transporting the vehicle based on the vehicle information acquired by the camera around the vehicle. Therefore, it is possible to suppress a mismatch between the vehicle to be transported and the vehicle transport device 1.
[0075] 9 is a flowchart showing a control routine for vehicle transport processing in the second embodiment. This control routine is executed by the processor 94 of the server 90 in accordance with a computer program stored in the memory 93 of the server 90.
[0076] First, in step S201, the vehicle information acquisition unit 95 determines whether vehicle transportation has been requested. For example, when a user of the vehicle transportation service requests vehicle transportation, the user operates a terminal device such as the vehicle's HMI or the user's mobile terminal to input request information into the terminal device. The request information includes a desired parking location (such as the user's home), vehicle identification information (such as license plate information), and the like. When the user has completed inputting the request information, the terminal device transmits a transportation request notification including the request information to the server 90 via the wireless base station 80 and the communication network 81.
[0077] Therefore, the vehicle information acquisition unit 95 determines that vehicle transportation is requested when a transportation request notification is sent from the terminal device to the server 90. If it is determined in step S201 that vehicle transportation is not requested, this control routine ends. On the other hand, if it is determined in step S201 that vehicle transportation is requested, this control routine proceeds to step S202.
[0078] Next, in step S202, the vehicle information acquisition unit 95 acquires position information of the vehicle to be transported. The vehicle position information is included in the transportation request notification transmitted from the terminal device to the server 90, and is, for example, the current position of the vehicle detected by a GNSS receiver provided in the terminal device.
[0079] Next, in step S203, the vehicle information acquisition unit 95 identifies cameras around the vehicle to be transported based on the position information of the vehicle to be transported. Specifically, the vehicle information acquisition unit 95 compares the position information of the vehicle to be transported with the position information of cameras within the target area, and identifies the camera closest to the vehicle to be transported. Note that the cameras within the target area may include not only fixed cameras that always capture a predetermined range, but also cameras mounted on vehicles or drones.
[0080] Next, in step S204, the vehicle information acquisition unit 95 acquires vehicle information based on the image generated by the camera identified in step S203. As in step S102 in Fig. 8, the vehicle information is, for example, the vehicle name, model, or size type information (for example, large vehicle, medium-sized vehicle, normal vehicle, etc.), or includes at least one of the vehicle width, vehicle length, tire inch size, and wheelbase.
[0081] Next, in step S205, similar to step S103 in Figure 8, the transportation plan creation unit 96 selects a specific type of vehicle transport device 1 from among multiple types of vehicle transport devices 1 as the vehicle transport device that will transport the vehicle to be transported, based on the vehicle information acquired by the vehicle information acquisition unit 95.
[0082] Next, in step S206, the transportation plan creation unit 96 determines the destination of the vehicle to be transported. For example, the transportation plan creation unit 96 selects the desired parking location included in the transportation request notification as the destination of the vehicle. Note that, if the vehicle to be transported is a rental car or a shared car that is dropped off by the user, the transportation plan creation unit 96 may select a predetermined storage location that stores such vehicles as the destination of the vehicle.
[0083] Next, in step S207, the transportation plan creation unit 96 transmits a transportation instruction to the specific type of vehicle transportation device 1 selected in step S205. The transportation instruction includes the current position of the vehicle to be transported, information on the destination, etc. After step S207, this control routine ends.
[0084] In addition, when the size of the vehicle can be estimated based on the vehicle position information, for example, when the current position of the vehicle is in an area (parking lot, etc.) dedicated to large vehicles, the transportation plan creation unit 96 may select a vehicle transportation device that transports the vehicle based on the vehicle position information. In addition, instead of an image generated by a camera around the vehicle to be transported, information input in advance to a terminal device such as the vehicle's HMI or a user's mobile terminal may be transmitted from the terminal device to the server 90 as vehicle information.
[0085] <Other embodiments> Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and changes can be made within the scope of the claims. For example, the vehicles transported by the vehicle transport device 1 may include two-wheeled vehicles, three-wheeled vehicles, small one-seater mobility vehicles, etc.
[0086] Furthermore, a computer program that causes a computer to realize the functions of each unit of the processor 94 of the server 90 may be provided in a form stored in a computer-readable recording medium. The computer-readable recording medium is, for example, a magnetic recording medium, an optical recording medium, or a semiconductor memory. [Explanation of symbols]
