Description

[Technical field]

[0001] The present invention relates to a vehicle operation system for operating a vehicle equipped with a ramp device that deploys and retracts a ramp that forms a passenger boarding and alighting passageway. [Background technology]

[0002] A method has been proposed for a vehicle equipped with a slope device, in which a sensor mounted on the vehicle is used to search for available parking space, and a slope is deployed to determine as a parking area an area that has a space where wheelchairs can board and disembark, and a route that allows the wheelchair to move from the vehicle to the destination when it has disembarked, and where there are no obstacles, bumps, or grooves in the boarding and disembarking space (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-162042 A Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, route buses and the like that run on predetermined routes have also been equipped with ramp devices. Since such route buses have fixed operating hours, it is necessary to shorten the time it takes to deploy the ramp. However, in the conventional technology described in Patent Document 1, the space available for deploying the ramp is checked every time the vehicle stops, so it takes time to deploy the ramp after stopping, making it difficult to apply this technology to a vehicle operation system that runs on a predetermined route, such as a route bus.

[0005] Therefore, an object of the present invention is to shorten the deployment time of a ramp when the vehicle is stopped in a vehicle operation system that operates a vehicle equipped with a ramp device. [Means for solving the problem]

[0006] The vehicle operation system of the present invention is provided with a slope device that deploys and stores a slope forming a passenger boarding and alighting passageway, and a control device that controls the deployment and storage of the slope of the slope device, and includes a plurality of vehicles traveling along a predetermined route, and a server that communicates with the control device of each of the vehicles and has a slope deployment possible map that indicates whether the slope can be deployed on map data on which planned stopping positions are marked, the slope deployment map includes a first mark indicating that the slope can be deployed at the planned stop position, a second mark indicating that the slope can be deployed at a position slightly ahead of the planned stop position on the predetermined route, and a third mark indicating that the slope can be deployed at a position slightly before the planned stop position on the predetermined route, The control device of each of the vehicles receives the slope deployable map from the server; When the first mark is displayed at the planned stop position, The planned stopping position In front The slope device deploys each of the slopes. When the second mark is displayed at the planned stop position, the vehicle is moved to a position slightly beyond the planned stop position, and then the slope device deploys the slope; when the third mark is displayed at the planned stop position, the vehicle is moved to a position slightly before the planned stop position, and then the slope device deploys the slope; It is characterized by:

[0007] In this way, the slope is deployed at the planned stopping location based on the slope deployment map received from the server, eliminating the need to determine whether or not the slope can be deployed using a sensor or the like each time the vehicle stops, thereby shortening the time it takes to deploy the slope when the vehicle is stopped.

[0008] In the vehicle operation system of the present invention, at least one of the plurality of vehicles is equipped with an imaging device that captures images of the surroundings of the planned stopping position while the vehicle is traveling, and the control device of the one vehicle determines whether the slope can be deployed at the planned stopping position based on the images captured by the imaging device, maps whether the slope can be deployed on map data on which the planned stopping position is marked, and transmits the mapping information to the server, and the server may store the mapping information received from the control device of the one vehicle in the slope deployment map.

[0009] In this way, while the slope-equipped vehicle is operating, images of the area around the planned stopping position are obtained by the imaging device, and a mapping is performed to determine whether the slope can be deployed based on the obtained images. The mapping information is then sent to the server and stored in the server's slope deployment map. This eliminates the need to map whether the slope can be deployed using equipment other than the vehicles that make up the vehicle operation system, and makes it possible to construct a slope deployment map in a simple manner.

[0010] In addition, in the vehicle operation system of the present invention, the control devices of the multiple vehicles may communicate with each other, and each of the control devices may receive the mapping information from the other vehicles, and based on the received mapping information, deploy the slope by the slope device at the planned stopping position.

[0011] In this way, mapping information is received from other vehicles without going through a server, and the ramp is deployed based on this mapping information, so there is no need to use a sensor or the like to determine whether or not to deploy the ramp each time the vehicle stops at a planned stopping location, and the time it takes to deploy the ramp when the vehicle is stopped can be shortened.

[0012] In the vehicle operation system of the present invention, the vehicle may be a public bus, and the planned stop location may be a bus stop.

[0013] To shorten operation time of a passenger bus equipped with a ramp device by shortening the time it takes to deploy the ramp when the bus is stopped.

[0014] In the vehicle operation system of the present invention, the public bus has a door for boarding and alighting attached to the side of the body, the slope device deploys the slope below the door toward the outside in the vehicle width direction, the imaging device is attached around the door and acquires an image of a first area where the slope is deployed, an image of a second area where the front end of the slope touches the ground, and an image of a third area which is an area for passenger movement adjacent to the first area or the second area, and the control device analyzes the images of each area acquired by the imaging device and detects the presence of foreign objects in each area, unevenness or cracks in the ground or road in each area, and determines whether or not the slope can be deployed.

[0015] This makes it possible to reliably determine whether the ramp can be deployed. Effect of the Invention

[0016] INDUSTRIAL APPLICABILITY The present invention makes it possible to reduce the deployment time of a ramp when the vehicle is stopped in a vehicle operation system in which a vehicle equipped with a ramp device is operated. [Brief description of the drawings]

[0018] Hereinafter, the vehicle operation system 100 of the embodiment will be described with reference to the drawings. The arrows FR, UP, and RH shown in each drawing indicate the forward direction (travel direction), upward direction, and rightward direction of the vehicle 10a, respectively. The opposite directions of the arrows FR, UP, and RH indicate the rearward direction, downward direction, and leftward direction of the vehicle. Hereinafter, when the directions of front-rear, left-right, and up-down are simply used in the description, they refer to front-rear in the front-rear direction of the vehicle, left-right in the left-right direction of the vehicle (vehicle width direction), and up-down in the up-down direction of the vehicle, unless otherwise specified.

[0019] As shown in FIG. 1, the vehicle operation system 100 is composed of a plurality of vehicles 10a, 10b, and 10c, and a server 50. The plurality of vehicles 10a, 10b, and 10c have the same structure, and are each connected to the server 50 via a communication line 58. The plurality of vehicles 10a, 10b, and 10c communicate with each other to exchange data. The plurality of vehicles 10a, 10b, and 10c each have a double-door 12 on the side, and a slope 22 disposed under the door 12 and deployed toward the outside in the vehicle width direction. In this embodiment, the number of vehicles is described as three, but any number of vehicles may be used as long as there is more than one.

[0020] First, the vehicle 10a will be described with reference to Figures 2 to 5. Figure 2 shows a state in which the vehicle 10a is parked in front of a bus stop 83, the doors 12 are closed, and the ramp 22 is stored.

[0021] The vehicle 10a is an electric bus capable of autonomous driving. As shown in Fig. 2, the vehicle 10a includes a body 101, a door device 11, a slope device 21, a camera 27 serving as an imaging device, a communication device 35a, a door slope control device 31, a travel control device 41, a position detection device 45, a sensor 44, a battery 46, a drive motor 47, and wheels 48.

[0022] The body 101 is symmetrical from front to rear, and includes a passenger compartment 102 inside. The floor 103 of the passenger compartment 102 is flat, and seats (not shown) for the passengers to sit in are arranged inside the passenger compartment 102.

[0023] The door device 11 is composed of a double-hinged door 12 that is provided on the side of a body 101 and slides along the side of the body 101, a motor 13 that opens and closes the door 12, and a control unit 14 that controls the operation of the motor 13.

[0024] The slope device 21 is provided under the floor 103 of the body 101. The slope device 21 is composed of a slope 22 that is deployed toward the outside of the body 101 in the vehicle width direction, a motor 23 that deploys and retracts the slope 22, and a control unit 24 that controls the motor 23.

[0025] The camera 27 is attached to the side of the body 101 above the door 12, and captures images of the surroundings of the bus stop 83 where the bus is scheduled to stop.

[0026] The communication device 35a, the door / slope control device 31, the travel control device 41, the sensor 44, and the position detection device 45 are disposed inside the body 101. The battery 46 is disposed beside the slope device 21 under the floor 103. The drive motor 47 of the vehicle 10a is an in-wheel motor built into the inside of a wheel 48. Note that the drive motor 47 may be configured to be mounted on the body 101 and drive the wheel 48 instead of being an in-wheel motor.

[0027] As shown in Fig. 3, when the vehicle 10a stops and passengers get on and off, the door device 11 opens the door 12 for passengers to get on and off. When the door 12 is opened, a flat vehicle interior 102 appears. In addition, when the vehicle 10a stops and the door 12 is opened, the slope device 21 deploys a slope 22 toward the outside of the body 101 in the vehicle width direction. As shown in Fig. 4, the tip 22a of the deployed slope 22 comes into contact with the sidewalk 82, forming a boarding and alighting passageway to the floor 103 for passengers on the sidewalk 82.

[0028] As shown in FIG. 3 and FIG. 4, the camera 27 captures an image of a first region 85 where the slope 22 is deployed, and an image of a second region 86 where the tip 22a of the slope 22 touches the ground. The camera 27 also captures an image of a third region including a passenger movement region 88 on the side of the vehicle adjacent to the first region 85 or the second region 86, a passenger movement region 87a diagonally forward of the vehicle 10a, and a passenger movement region 87b diagonally rearward of the vehicle 10a. Here, the first region 85 is a region where the slope 22 is deployed between the vehicle 10a parked on the roadway 81 and the sidewalk 82. The second region 86 is a region above the sidewalk 82 where the tip 22a of the slope 22 touches the ground. The movement regions 87a, 87b, and 88 are also regions above the sidewalk 82. When the slope 22 is deployed above the roadway 81, the camera 27 captures images of the first area 85, the second area 86, and the moving areas 87a, 87b, and 88 above the roadway 81.

[0029] As shown in FIG. 5, the door device 11 and the slope device 21 are connected to a door slope control device 31, and the door 12 is opened and closed and the slope 22 is deployed and retracted based on commands from the door slope control device 31. The camera 27 is also connected to the door slope control device 31, and image data captured by the camera 27 is input to the door slope control device 31. The door slope control device 31 is connected to a communication device 35a. The communication device 35a communicates with a server 50 via an external communication line 58 to exchange data with the server 50. Therefore, the door slope control device 31 communicates with the server 50 via the communication device 35a and the communication line 58 to exchange data. Here, the communication line 58 may be, for example, the Internet or a telephone communication line.

[0030] The driving motor 47 of the vehicle 10a, the battery 46, the sensors 44 such as an acceleration sensor and a speed sensor mounted on the vehicle 10a, and the position detection device 45 incorporating a GPS device for detecting the traveling position of the vehicle 10a are connected to the driving control device 41. The driving motor 47 and the battery 46 operate according to commands from the driving control device 41. Data such as acceleration and speed detected by the sensor 44 is input to the driving control device 41. Position data of the vehicle 10a detected by the position detection device 45 is also input to the driving control device 41. The driving control device 41 is also connected to the communication device 35a, and communicates with the server 50 via the communication device 35a and a communication line 58 to exchange data with the server 50.

[0031] The control unit 14 of the door device 11 is configured with a computer having a CPU 15, which is a processor that processes information, and a memory 16 that stores operation programs and control data. Similarly, the control unit 24 of the slope device 21 is configured with a computer having a CPU 25, which is a processor that processes information, and a memory 26 that stores operation programs and control data. Similarly, the door slope control device 31 and the travel control device 41 are configured with computers having CPUs 32, 42, which are processors that process information, and memories 33, 43. The door slope control device 31 stores mapping information 34a inside the memory 33. The mapping information 34a will be described later with reference to FIG. 6.

[0032] The server 50 is composed of a computer having a CPU 51, which is a processor that performs information processing, and a memory 52 that stores operation programs and the like, and is connected to a database unit 53 that stores a large amount of data. The database unit 53 stores an operation database 54 that is referenced when controlling the operation of the vehicle 10a, and a slope deployment map 55 that indicates whether the slope 22 can be deployed on map data on which the planned stopping positions are marked. The database unit 53 may be composed of, for example, a hard disk or an external memory device.

[0033] The operation database 54 stores dispatch information such as the travel routes and stopping places of the multiple vehicles 10a. The database unit 53 may also include a database of detailed information on maps and travel routes. The slope deployment map 55 will be described later with reference to FIG. 7.

[0034] Next, the mapping information 34a stored in the memory 33 of the door / slope control device 31 of the vehicle 10a will be described with reference to FIG. 6. As shown in FIG. 6, the mapping information 34a is data that displays the route 91 and the positions of the bus stops 71-76 on the map data of the operating area of ​​the vehicle 10a, and indicates whether the ramp 22 can be deployed by using marks for each of the bus stops 71-76. The open circle marks of the bus stops 71, 74, and 76 in the figure indicate that the ramp 22 can be deployed. The black circle mark of the bus stop 72 indicates that the ramp 22 cannot be deployed. The circle mark of the bus stop 73 with hatching downward to the right indicates that the ramp 22 can be deployed a little ahead of the bus stop 73. The circle mark of the bus stop 75 with hatching downward to the left indicates that the ramp 22 can be deployed a little before the bus stop 73. 6, reference numerals 61-64 and 66-69 denote buildings such as buildings built in the service area, and reference numeral 65 denotes a park. A sidewalk 82 is located between a roadway 81 on which the vehicle 10a travels and each of the buildings 61-64 and 66-69. Therefore, each of the bus stops 71-76 is provided on the sidewalk 82.

[0035] In the initial state before the vehicle 10a first travels along the travel route 91, only the map data, the travel route 91, and the positions of the bus stops 71-76 are displayed in the mapping information 34a, and the white circles, black circles, and hatched circles are not displayed. When the vehicle 10a travels along the travel route 91, the camera 27 acquires images of the periphery of each bus stop 71-76, and the CPU 32 of the door / slope control device 31 determines whether the ramp 22 can be deployed based on the acquired images, maps each of the bus stops 71-76 in the mapping information 34a, and generates the mapping information 34a. The door / slope control device 31 then transmits the generated mapping information 34a to the server 50.

[0036] The configuration of the vehicle 10a has been described above, but the vehicles 10b and 10c have the same configuration as the vehicle 10a and are composed of similar functional blocks. The communication device 35a of the vehicle 10a and the communication device 35b of the vehicle 10b each exchange data with the server 50 via the communication line 58. Therefore, each door slope control device (not shown) of the vehicles 10b and 10c exchanges data with the server 50 via the communication line 58. Also, the door slope control device 31 of the vehicle 10a exchanges data with each door slope control device (not shown) of the vehicles 10b and 10c via the communication line 58.

[0037] Furthermore, the communication device 35a of the vehicle 10a communicates with the communication device 35b of the vehicle 10b and the communication device 35c of the vehicle 10c via the communication line 58 to exchange data. The communication device 35a of the vehicle 10a, the communication device 35b of the vehicle 10b, and the communication device 35c of the vehicle 10c also exchange data with each other through inter-vehicle communication. Therefore, the door slope control device 31 of the vehicle 10a and the door slope control devices (not shown) of the vehicles 10b and 10c exchange data with each other through inter-vehicle communication.

[0038] In addition, each door / slope control device (not shown) of the vehicles 10b and 10c stores mapping information 34b and 34c similar to the mapping information 34a in an internal memory (not shown). The mapping information 34b and 34c is data that displays the operating route and the positions of bus stops on the map data of the operating area of ​​the vehicles 10b and 10c, and indicates whether the ramp 22 can be deployed by using a mark at each bus stop. The operating area of ​​the vehicles 10b and 10c may be different from or the same as the operating area of ​​the vehicle 10a. The door / slope control devices (not shown) of the vehicles 10b and 10c generate the mapping information 34b and 34c during operation, similar to the door / slope control device 31 of the vehicle 10a, and transmit the generated mapping information 34b and 34c to the server 50. Furthermore, the door / slope control device 31 of the vehicle 10a and the door / slope control devices (not shown) of the vehicles 10b and 10c exchange mapping information 34a, 34b, and 34c with each other through inter-vehicle communication.

[0039] Next, the slope deployment map 55 stored in the database unit 53 of the server 50 will be described with reference to FIG. 7. The slope deployment map 55 is data that displays whether the slope 22 can be deployed on map data on which bus stops are marked for the entire operation area of ​​the multiple vehicles 10a, 10b, and 10c operated by the vehicle operation system 100. Specifically, it is data that displays a combination of the mapping information 34a, 34b, and 34c transmitted from the door / slope control device 31 of the vehicles 10a, 10b, and 10c described above. FIG. 7 shows a case where the operation area of ​​the vehicles 10b and 10c is adjacent to the operation area of ​​the vehicle 10a. When the operation area of ​​the vehicles 10b and 10c partially overlaps with the operation area of ​​the vehicle 10a, parts of the mapping information 34a, 34b, and 34c are displayed in an overlapping manner.

[0040] Next, the operation of the vehicle operation system 100 will be described with reference to Fig. 8. First, the operation of generating mapping information 34a while the vehicle 10a is operating will be described with reference to Fig. 8. In the following explanation, it is assumed that the vehicle 10a departs from a bus stop 71 in front of the building 61 shown in Fig. 6, travels around the operating area, and travels along a predetermined operating route 91 that returns to the bus stop 71.

[0041] As shown in step S101 of FIG. 8, the vehicle 10a starts traveling from the garage and heads toward the bus stop 71, which is the starting point shown in FIG. 6. Then, as shown in step S102 of FIG. 8, the vehicle stops at the bus stop 71. Then, as shown in step S103 of FIG. 8, the door / slope control device 31 obtains an image of a first area 85 where the slope 22 is deployed and an image of a second area 86 where the tip 22a of the slope 22 touches the ground by the camera 27, as described with reference to FIG. 3 and FIG. 4. In addition, the door / slope control device 31 obtains an image of a third area including a passenger movement area 88 on the side of the vehicle adjacent to the first area 85 or the second area 86, a passenger movement area 87a diagonally forward of the vehicle 10a, and a passenger movement area 87b diagonally rearward of the vehicle 10a. Then, as shown in step S104 of Fig. 8, the CPU 32 of the door / slope control device 31 analyzes the image captured by the camera 27 to check whether or not there is a foreign object 95, a crack 96, or an unevenness 97 shown in Figs. 2 and 3 in each of the areas 85, 86, 87a, 87b, and 88 on the sidewalk 82. Since there is no foreign object 95, a crack 96, or an unevenness 97 in each of the areas 85, 86, 87a, 87b, and 88 at the bus stop 71, the CPU 32 of the door / slope control device 31 judges YES in step S105 of Fig. 8 and proceeds to step S106 of Fig. 8. Then, in step S106 of Fig. 8, the door 12 is opened by the door device 11, and the slope 22 is deployed by the slope device 21.

[0042] Next, the CPU 32 of the door / slope control device 31 proceeds to step S107 in Fig. 8 and maps a white circle indicating that the ramp 22 can be deployed at the position of the bus stop 71 in the mapping information 34a stored in the memory 33. Then, the CPU 32 of the door / slope control device 31 determines in step S108 whether the bus stop 71 is the last bus stop of the route 91. Since the bus stop 71 is not the last bus stop, the CPU 32 of the door / slope control device 31 determines NO in step S108 in Fig. 8 and returns to step S102 in Fig. 8.

[0043] Similarly, the vehicle 10a travels along the route 91 and stops at the next bus stop 72. The door / slope control device 31 obtains an image of the periphery of the bus stop 72 with the camera 27 and analyzes the image. Since the bus stop 72 has foreign objects 95, cracks 96, and unevenness 97 in each of the areas 85, 86, 87a, 87b, and 88, the CPU 32 of the door / slope control device 31 judges NO in both steps S105 and S110 in FIG. 8 and proceeds to step S113 in FIG. 8. Then, the CPU 32 of the door / slope control device 31 opens only the door 12 by the door device 11 without deploying the slope 22. Then, the CPU 32 of the door / slope control device 31 proceeds to step S107 in FIG. 8, maps a black circle indicating that the slope 22 cannot be deployed at the position of the bus stop 72, judges NO in step S108 in FIG. 8, and returns to step S102 in FIG. 8.

[0044] Similarly, since the bus stop 73 has foreign objects 95 and unevenness 97 in the areas 85 and 86 and the slope 22 cannot be deployed at the bus stop 73, but there is an area slightly ahead of the bus stop 73 where the slope 22 can be deployed, the CPU 32 of the door / slope control device 31 judges NO in step S105 of FIG. 8, judges YES in step S110 of FIG. 8, and outputs a command to the driving control device 41 to move the vehicle 10a slightly forward in step S111 of FIG. 8. The driving control device 41 drives the drive motor 47 based on this command to move the vehicle 10a forward to a predetermined position. When the vehicle 10a reaches the predetermined position, the CPU 32 of the door / slope control device 31 captures an image of the periphery of the stop position with the camera 27, as shown in step S112 of FIG. 8, and analyzes the captured image to determine whether the slope 22 can be deployed. If the CPU 32 of the door / slope control device 31 determines YES in step S112 of Fig. 8, the process proceeds to step S106 of Fig. 8 to open the door 12 and deploy the slope 22. Then, the CPU 32 of the door / slope control device 31 proceeds to step S107 of Fig. 8 to map a circle hatched downward to the right at the position of the bus stop 73, indicating that there is an area slightly beyond the bus stop 73 where the slope 22 can be deployed.

[0045] If the CPU 32 of the door / slope control device 31 judges NO in step S112 of Fig. 8, the process proceeds to step S113 of Fig. 8, where the ramp 22 is not deployed, only the door 12 is opened, and the process proceeds to step S107 of Fig. 8. In this case, the CPU 32 of the door / slope control device 31 maps a black circle indicating that the ramp 22 cannot be deployed at the position of the bus stop 73 in the mapping information 34a.

[0046] Similarly, the CPU 32 of the door / slope control device 31 confirms that the ramp 22 can be deployed at the bus stops 74 and 76, and maps white circles indicating that the ramp 22 can be deployed at the positions of the bus stops 74 and 76 in the mapping information 34a. The CPU 32 of the door / slope control device 31 also confirms that the ramp 22 can be deployed slightly before the bus stop 75 at the bus stop 75, and maps a circle hatched downward to the left at the position of the bus stop 75 in the mapping information 34a, indicating that there is an area slightly before the bus stop 75 where the ramp 22 can be deployed.

[0047] Then, when the bus returns to the bus stop 71, the CPU 32 of the door / slope control device 31 judges YES in step S108 of FIG. 8, proceeds to step S109 of FIG. 8, and transmits to the server 50 mapping information 34a in which marks are displayed at the positions of each of the bus stops 71 to 76 on the map data, as shown in FIG. 6.

[0048] The server 50 stores the mapping information 34a received from the door slope control device 31 of the vehicle 10a in the position of the operating area of ​​the vehicle 10a in a slope deployment map 55 shown in FIG.

[0049] In the above, it has been explained that the vehicle 10a generates the mapping information 34a while traveling and transmits it to the server 50, and the server 50 stores the mapping information 34a in the slope deployment map 55. Similarly, the vehicles 10b, 10c also generate mapping information 34b, 34c while traveling and transmit it to the server 50, and the server 50 stores the mapping information 34b, 34c in the slope deployment map 55. In this way, the server 50 can make the slope deployment map 55 into data that indicates whether the slope 22 can be deployed on map data on which bus stops are marked for the entire operating area of ​​the multiple vehicles 10a, 10b, 10c operated by the vehicle operating system 100.

[0050] Next, the operation of the vehicle 10a to deploy the slope 22 based on the slope deployment map 55 stored in the database unit 53 of the server 50 will be described with reference to FIG.

[0051] As shown in step S201 of Fig. 9, the door slope control device 31 of the vehicle 10a communicates with the server 50, downloads information on the operating area of ​​the vehicle 10a from the slope development map 55 of the server 50, and stores the information in the memory 33. At this time, the data to be downloaded is partial data of the slope development map 55, and is the same data as the mapping information 34a shown in Fig. 6. Note that the vehicle 10a may download the entire slope development map 55 of the server 50, rather than just a part of it.

[0052] When the vehicle 10a starts traveling in step S101 of Fig. 9 and arrives at the bus stops 71-76 as shown in step S102 of Fig. 9, the CPU 32 of the door / slope control device 31 refers to the marks displayed at the bus stops 71-76 in the partial data of the slope deployment map 55 stored in the memory 33 and judges whether the bus stops 71-76 are white circles indicating bus stops where the slope 22 can be deployed as shown in step S202 of Fig. 9. If the answer is YES in step S202 of Fig. 9, the process proceeds to step S106 of Fig. 9 to open the door 12 and deploy the slope 22. If the answer is NO in step S202 of Fig. 9, the CPU 32 judges whether the marks at the bus stops 71-76 are circles hatched downward to the right or circles hatched downward to the left as shown in S203 of Fig. 9. When the marks of the bus stops 71 to 76 are these circles, the CPU 32 of the door / slope control device 31 judges YES in step S203 of Fig. 9, moves the vehicle 10a as shown in step S111 of Fig. 9, and then opens the doors 12 and deploys the slope 22 in step S106 of Fig. 9. When the marks of the bus stops 71 to 76 are black circles indicating that the slope 22 cannot be deployed, the CPU 32 of the door / slope control device 31 judges NO in steps S202 and S203 of Fig. 9, and proceeds to step S113 of Fig. 9 to open only the doors 12 but not to open the slope 22.

[0053] As described above, in the vehicle operation system 100 of the embodiment, the vehicle 10a deploys the ramp 22 at the bus stops 71-76 based on the ramp deployment map 55 received from the server 50. This eliminates the need to determine whether or not the ramp 22 can be deployed using a sensor or the like each time the vehicle stops at one of the bus stops 71-76, thereby shortening the time it takes to deploy the ramp when the vehicle is stopped.

[0054] As described above, in the vehicle operation system 100 of the embodiment, the door slope control device 31 of the vehicle 10a and the door slope control devices (not shown) of the vehicles 10b and 10c exchange mapping information 34a, 34b, and 34c with each other through vehicle-to-vehicle communication. As a result, when the vehicle 10b travels on the same route 91 as the vehicle 10a, the vehicle 10b may receive the mapping information 34a from the vehicle 10a without going through the server 50, and deploy the slope 22 based on the mapping information 34a. This eliminates the need to determine whether or not to deploy the slope 22 using a sensor or the like each time the vehicle stops at one of the bus stops 71 to 76, and the time required to deploy the slope when the vehicle stops can be shortened.

[0055] In addition, when the vehicle 10a has downloaded a part or all of the slope deployment map 55 from the server 50, the door / slope control device 31 of the vehicle 10a and each door / slope control device (not shown) of the vehicles 10b and 10c may transmit and receive a part or all of the slope deployment map to each other through vehicle-to-vehicle communication, and deploy the slope 22 based on this.

[0056] In the vehicle operation system 100 of the above embodiment, the vehicle 10a has been described as an electric bus capable of autonomous driving, but the present invention is not limited to this, and may be an engine-driven vehicle capable of autonomous driving. Also, the vehicle may be a passenger vehicle such as a taxi that carries passengers, instead of a passenger bus. Also, the planned stop location may be a predetermined disembarking location or a predetermined boarding location, instead of the bus stops 71 to 76. Also, the door / slope control device 31 of the vehicle 10a and each door / slope control device (not shown) of the vehicles 10b and 10c may not communicate with each other between the vehicles, but may exchange data with the server 50 via the communication line 58, or may be configured to exchange data between the door / slope control device 31 of the vehicle 10a and each door / slope control device (not shown) of the vehicles 10b and 10c via the communication line 58.

[0057] In the above-described vehicle operation system 100, the vehicles 10a, 10b, and 10c have the same configuration, and the vehicles 10a, 10b, and 10c generate mapping information 34a, 34b, and 34c during operation and transmit it to the server 50, and the server 50 stores the mapping information 34a, 34b, and 34c in the slope deployment map 55. However, this is not limited to the above, as long as the data indicates whether the slope 22 can be deployed on map data with bus stops marked for the entire operation area of ​​the multiple vehicles 10a, 10b, and 10c operated by the vehicle operation system 100. For example, the vehicles 10a and 10b may generate the mapping information 34a and 34b and transmit it to the server 50, and the vehicle 10c may not generate mapping information, but may download part or all of the slope deployment map 55 from the server 50 and deploy the slope 22 based on this.

[0058] The vehicle operation system 100 consisting of the vehicles 10a, 10b, and 10c equipped with the slope device 21 and the server 50 has been described above. The vehicle 10a used in the vehicle operation system 100 can be summarized as the following vehicle.

[0059] (1) A ramp device for deploying and storing a ramp that forms a passenger boarding and alighting passageway; A slope device-equipped vehicle that communicates with a server having a slope deployment map that indicates whether the slope can be deployed on map data on which a planned stopping position is marked, and that is equipped with a control device that controls the deployment and storage of the slope of the slope device, and travels along a predetermined route, The control device receives the slope deployment map from the server, and deploys the slope using the slope device at the planned stopping position based on the received slope deployment map.

[0060] In this way, the slope is deployed at the planned stopping location based on the slope deployment map received from the server, eliminating the need to determine whether or not the slope can be deployed using a sensor or the like each time the vehicle stops, thereby shortening the time it takes to deploy the slope when the vehicle is stopped.

[0061] (2) A vehicle equipped with a slope device as described in (1), An imaging device is provided for acquiring images of the surroundings of the planned stop position during operation, The control device may determine whether the slope can be deployed at the planned stopping position based on the image acquired by the imaging device, map whether the slope can be deployed on map data on which the planned stopping position is marked, and transmit the mapping information to the server to be stored in the slope deployment map of the server.

[0062] While the slope-equipped vehicle is in operation, an imaging device captures images of the area around the planned stopping position, and based on the captured images, a mapping is performed to determine whether the slope can be deployed. The mapping information is then sent to a server and stored in the server's slope deployment map. This eliminates the need to map whether the slope can be deployed using equipment other than the slope-equipped vehicle, and a slope deployment map can be constructed in a simple manner.
