Additionally, the operator system (40) receives progress information (PRG) from the management device (30).

[0043] 1-5. Display Devices and Mobile Terminals

[0044] One or more display devices (50) are installed in the waiting area (5). Additionally, at least one of the one or more candidate operators (4) waiting in the waiting area (5) possesses a mobile terminal (60). Each of the display device (50) and the mobile terminal (60) can communicate with the management device (30) via a communication network. Each of the display device (50) and the mobile terminal (60) is configured to receive presentation information (PST) described below from the management device (30) and to notify one or more candidate operators (4) of the received presentation information (PST). In this way, each of the display device (50) and the mobile terminal (60) corresponds to an example of an "information providing device" regarding the present disclosure.

[0045] Specifically, the display device (50) includes a display (51), one or more processors (52) (hereinafter simply referred to as processors (52)), and one or more memory devices (53) (hereinafter simply referred to as memory devices (53)). The processor (52) performs various processing related to the control of the display (51), etc. The memory device (53) stores various information.

[0046] The information providing program (PROG3) is a computer program executed by a processor (52). The function of the display device (50) may be realized through the cooperation of the processor (52) executing the information providing program (PROG3) and the memory device (53).

The displays (51 and 61) and the speaker (62) correspond to examples of the “notification device.” That is, in the example of the display device (50), notification of the presentation information (PST) is made by displaying the presentation information (PST) by the display (51). Also, in the example of the mobile terminal (60), notification of the presentation information (PST) is made by displaying the presentation information (PST) using the display (61). Alternatively, notification of the presentation information (PST) may be made by notification of the presentation information (PST) by voice using the speaker (62) together with or instead of the display.

[0050] 2. Communication between the management device (remote operation management center) and the service provider system

[0051] As described above, each service provider system (40) transmits request information (REQ) to the management device (30), and the management device (30) transmits progress information (PRG) to the service provider system (40) that transmitted the request information (REQ). The format of the request information (REQ) and progress information (PRG) transmitted in this manner is standardized between the management device (30) and each service provider system (40).

[0052] 2-1. Request Information (REQ) from Service Provider System

[0053] The following are various specific examples of Request Information (REQ) indicating the details of a remote operation request.

[0054] (Urgency)

[0055] Request information (REQ) may include information on the "urgency of remote operation" at the time of the request. Urgency indicates the degree to which the rapid initiation of remote operation is required. Urgency is determined by a single level (e.g., level 3 or level 5) pre-specified by the remote operation management center (3). Situations requiring the rapid initiation of remote operation include, for example, situations where it is necessary to move the vehicle (10) quickly, or situations where it is necessary to hurry the vehicle (10) to a target location. The following is an example of setting the urgency. That is, in the example where autonomous driving backup is requested as a remote operation service, it is necessary to move the vehicle (10) quickly due to reasons such as the autonomous vehicle stopping on the road. For this reason, the urgency is set to "High." Also, in the example where delivery of a shared car is requested as a remote operation service, it is necessary to send the shared car to the customer by a designated time. For this reason, the urgency is set to "Medium." Additionally, in cases where the return of a rental car is requested as a remote operation service, what is required is to return the rental car to the business office (waiting area) after use, so there is no need to rush. For this reason, the urgency level is set to "Low."

[0056] (State of the moving object)

[0057] Additionally, the request information (REQ) may include information indicating the "state of the vehicle (10)" at the time of the request. This information is necessary for the remote operator (2) to initiate the requested remote operation. For example, the information indicating the state of the vehicle (10) is text information such as "parked in a garage" or "autonomous vehicle stopped in the middle of the road." Alternatively, the information indicating the state of the vehicle (10) may include, along with text information, one or both of the image information of the vehicle (10) at the time of the request and surrounding information of the vehicle (10). More specifically, the image information is, for example, an image (including video) from a camera mounted on the vehicle (10).

[0058] (Types of mobile bodies, and types of remote operation services)

[0059] Additionally, the request information (REQ) may include information indicating the type of mobile object (10) that is the target of the requested remote operation. An example of the type of mobile object (10) has already been described. Additionally, the request information (REQ) may include information indicating the type of the requested remote operation service. An example of the type of remote operation service has already been described.

[0060] (Completion condition)

[0061] Additionally, the request information (REQ) may include information indicating the completion condition of the requested remote operation. In other words, the completion condition is a condition for terminating the remote operation. For example, the completion condition is "moving the moving object (10) to the goal point" or "picking up a person or object during movement by remote operation."

[0062] (Branch Information)

[0063] Additionally, the request information (REQ) may include point information, that is, information indicating the locations of various points such as the start point, goal point, and passing point in the movement of the mobile body (10) by the remote operation service.

[0064] (Supplementary Information)

[0065] Additionally, the Request (REQ) may include supplementary information. In remote operation services where picking up a person or object is required, the supplementary information is, for example, information about the person or object to be picked up (e.g., name and image).

[0066] 2-2. Progress Information to Service Provider System (PRG)

[0067] Progress information (PRG) is information indicating the progress status of remote operation after the request has been initiated. Progress information (PRG) may include current status information indicating the current state of the mobile body (10) after the request has been initiated. For example, current status information may include "remote operation has not yet started," "remote operator (2) is being selected," and "remote operation is in progress." These current status information may be obtained, for example, based on the history information of processing executed by the processor (33). In addition, along with "remote operation is in progress," current status information may include information (e.g., ID number, proficiency, and evaluation score) of the remote operator (2) performing the remote operation. The information of the remote operator (2) is obtained in advance and included in management information (MNG).

[0068] Additionally, the progress information (PRG) may include the current location information of the mobile body (10) after the request has started. The current location information can be obtained from the mobile body information (MOV).

[0069] Additionally, the progress information (PRG) may include the following ancillary information. For example, in a remote operation service regarding the transport of a person or object, the ancillary information may include information indicating whether the person or object has been picked up, information about the picked-up person or object (such as an image representing the person or object), and information indicating whether the transport has been completed. These ancillary information may be obtained from the moving object information (MOV).

[0070] The service provider can properly determine the progress of the remote operation by receiving progress information (PRG) from the management device (30) (remote operation management center (3)).

[0071] 3. Provision of information to the candidate manipulator (Presented Information (PST))

[0072] As described above, the management device (30) (control device (32)) generates presentation information (PST) based on request information (REQ). Then, in order to present the generated presentation information (PST) to one or more candidate operators (4) for remote operation regarding the request information (REQ), the management device (30) transmits the presentation information (PST) to an information providing device (display device (50), etc.). The information providing device that has acquired the presentation information (PST) notifies one or more candidate operators (4) of the presentation information (PST) by displaying the presentation information (PST) on a notification device (display (51), etc.) (for example, see FIG. 4 or FIG. 5 described later).

[0073] In this embodiment, the notification of the above-described presentation information (PST) is executed for one or more candidate operators (4) before the remote operator (2) who accepts the request for remote operation regarding the request information (REQ) is determined.

[0074] 3-1. Examples of Information Providing Devices of the Transmitting Target

[0075] In the example of the remote operation system (1) shown in FIG. 1, the "information providing device" that is the transmission target of the presentation information (PST) is at least one of the display device (50) of the waiting place (5), the mobile terminal (60), and the remote operation device (20).

[0076] Specifically, in the example where one or more candidate operators (4) are waiting at a waiting place (5) as shown in FIG. 1, the management device (30) may transmit presentation information (PST) to each of the display device (50) and the mobile terminal (60). Alternatively, the management device (30) may transmit to only one of the display device (50) and the mobile terminal (60). Furthermore, the management device (30) may transmit presentation information (PST) not only to one or both of the display device (50) and the mobile terminal (60), but also to the remote operation device (20) that is scheduled to be operated by the remote operator (2) to perform remote operation regarding the request information (REQ). That is, the recipients of the notification of presentation information (PST) by the "information providing device" may include the remote operator (2) who starts remote operation after a candidate operator (4) is determined as the remote operator (2).

[0077] Meanwhile, in the example of a remote operation system having a dedicated remote operation device (20) for a candidate operator (4), the transmission of presentation information (PST) before the remote operator (2) is determined may be carried out as follows. That is, when the candidate operator (4) is waiting at a location where the dedicated remote operation device (20) is located (e.g., a remote cockpit), the management device (30) may transmit presentation information (PST) to the remote operation device (20) which functions as an "information providing device." Additionally, the "location where the remote operation device (20) is located" mentioned here may include not only, for example, the remote operation management center (3), but also a location outside the remote operation management center (3).

[0078] 3-2. Specific Examples of Presented Information (PST)

[0079] The presentation information (PST) may be identical to the request information (REQ). Alternatively, to make it easier for the remote operator (2) to understand and perform remote operation, the presentation information (PST) may include information processed or added based on the management information (MNG) of the management device (30) together with the request information (REQ) as follows. The management information (MNG) used here includes various information acquired in advance based on the mobile object information (MOV), etc. The various information mentioned here includes, for example, surrounding information of the area where remote operation is performed, past remote operation performance information, and characteristic information of the mobile object (10). The surrounding information mentioned here includes, for example, information indicating points that the remote operator (2) must pay attention to during remote operation (for example, locations of road subsidence and locations where road construction is underway). The past remote operation performance information includes, for example, information collected by the management device (30) from the mobile object information (MOV) during the movement of the mobile object (10) by past remote operation (for example, while the vehicle is driving). The characteristic information of the moving body (10) is, for example, information indicating the operational characteristics of individual types of moving bodies (10).

[0080] Here, examples of presentation information (PST) that are shared with some of the request information (REQ) are described. That is, for example, regarding the urgency, the type of mobile body (10), the type of remote operation service, the status of the mobile body (10), the completion condition, and the incidental information, the presentation information (PST) is identical to the request information (REQ).

[0081] Presentation information (PST) is additional information (PST1) not included in the request information (REQ), and may include, for example, additional information on required qualifications. The mobile body (10) subject to remote operation includes a mobile body that requires a dedicated driving qualification (e.g., automobiles and ships). The information on required qualifications is information on qualifications, such as driving qualifications, required of the remote operator (2) for remote operation (e.g., see FIG. 5).

[0082] Additionally, the presented information (PST) may include information on the difficulty of remote operation (D) as another example of additional information (PST1). The difficulty (D) is obtained, for example, from management information (MNG) (see Step S106 described below).

[0083] The presented information (PST) is processed information (PST2) obtained by processing based on the request information (REQ), and may additionally include, for example, information on the movement route. The information on the movement route is, for example, information on the movement route itself (e.g., the vehicle's driving route), information on intermediate passing points, and information on points requiring caution.

[0084] Information on the movement route is generated based on various types of information, such as the surrounding information of the area where remote operation is performed, information on past remote operation results, and characteristic information of the moving body (10), together with point information included in the request information (REQ). Specifically, as information on the movement route, the management device (30) calculates the optimal movement route of the moving body (10) by remote operation based on the point information and the various types of information. Specific examples of information on the movement route will be described later with reference to FIG. 4.

[0085] FIG. 4 is a drawing showing a first display example of presentation information (PST). The presentation information (PST) shown in FIG. 4 is displayed on a "notification device" such as a display (51). In the first display example, each piece of information constituting the presentation information (PST) corresponding to a request for remote operation is divided into individual display areas and displayed in an easy-to-understand manner.

[0086] Specifically, text information indicating a high level of urgency is displayed using large characters. Additionally, text information indicating the type of remote operation service (autonomous driving backup) is displayed. Furthermore, a combination of text information (MaaS vehicle) and an icon, which is an example of information indicating the type of mobility (10), is displayed along with the name, color, and identification number of the MaaS vehicle as supplementary information.

[0087] In addition, in the first display example, a combination of text information (stopped due to an obstacle, waiting for route recovery) and image information (IMG1), which is an example of information indicating the status (current status) of the MaaS vehicle at the time of the request, is displayed. Image information (IMG1) is an image from a vehicle-mounted camera. In image information (IMG1), marking is performed using Augmented Reality (AR) technology on the obstacles to be avoided that are included in the vehicle-mounted camera image.

[0088] In addition, in the first display example, a combination of text information (stopping at a specified angle at a specified goal location) and image information (IMG2), which is an example of information indicating a completion condition, is displayed. In this image information (IMG2), goal information (e.g., a goal frame indicating the goal location) is superimposed using AR technology on the same vehicle-mounted camera image as in the image information (IMG1). In this example, detailed goal information is displayed as a completion condition, including not only the specification of the goal location but also the specification of the angle of the MaaS vehicle when stopping at the goal location. Furthermore, the goal information is displayed in an easy-to-understand manner through visual means using AR superimposition display.

[0089] In addition, in the first display example, two image information (IMG3 and IMG4) are displayed as examples of information indicating a driving route (movement route) that avoids obstacles. Image information (IMG3) is a two-dimensional map information that shows the driving route viewed from above. Image information (IMG4) is a three-dimensional map information in which the driving route is superimposed using AR technology on a vehicle-mounted camera image identical to that of image information (IMG1). Through these image information (IMG3 and IMG4), the obstacle avoidance route is displayed in an easy-to-understand manner through visual means. Additionally, information on the driving route may be notified accompanied by voice information output by a speaker (62), etc.

[0090] In addition, in the first display example, numerical information (e.g., 1.0) is displayed as an example of information indicating the difficulty (D) of remote operation. Alternatively, the difficulty (D) may be displayed by text information such as, for example, “easy,” “normal,” or “hard.”

[0091] In addition, in the first display example, supplementary information is shown using a combination of text information and image information (IMG5 and IMG6). The text information is, for example, the name of the person or object to be picked up. The image information (IMG5 and IMG6) is, for example, an image of the person or object to be picked up. Furthermore, image information indicating points to be careful of, for example, when avoiding obstacles, is basically information on the driving route, but may be included in this supplementary information.

[0092] FIG. 5 is a diagram showing a second example of presentation information (PST). The presentation information (PST) shown in FIG. 5 is displayed on a "notification device" such as a display (51). In the second example of display, five presentation information (PSTs) corresponding to five remote operation requests that have not yet been determined by the remote operator (2) are organized as a list and displayed in an easy-to-understand manner. Each presentation information (PST) includes supplementary information along with information indicating the service (type of remote operation service), mobility (type of moving object), required qualifications, current status, and completion conditions, respectively. The contents of the individual information are as shown in FIG. 5. Additionally, when displaying presentation information (PST) based on a newly received request, the presentation information (PST) that is the subject of such display may be displayed in a manner that is easily distinguishable from presentation information (PST) corresponding to other requests. For example, the frame surrounding the presentation information (PST) that is the subject of the new display may be displayed in an overlapping manner, or a color different from the background color of other display areas may be used as the background color of the display area of ​​said presentation information (PST). Additionally, in this list, items may be displayed from top to bottom in order of the urgency of remote operation.

[0093] 3-3. Examples of Customizing Presentation Information (PST)

[0094] Additionally, the presentation information (PST) may be modified (customized) as follows by individual candidate manipulators (4).

[0095] For example, the presentation information (PST) may be generated differently depending on the proficiency of the candidate operator (4) for remote operation. Specifically, for example, for a candidate operator (4) with low experience, the management device (30) may generate presentation information (PST) that includes a lot of supplementary information (e.g., points to watch out for and advice). On the other hand, for a candidate operator (4) with high proficiency, the management device (30) may generate presentation information (PST) that does not include supplementary information that is obvious to the high proficiency. In addition, information on the proficiency of the candidate operator (4) for remote operation may be obtained based on the aforementioned past remote operation performance information included in the management information (MNG), for example.

[0096] Additionally, for example, when a remote operation regarding a specific remote operation service is requested from a candidate operator (4) specialized in a specific remote operation service, the management device (30) may generate presentation information (PST) that has content specialized in the specific remote operation service.

[0097] 4. Processing by management device

[0098] FIG. 6 is a flowchart illustrating an example of processing executed by a management device (30) for the provision of a remote operation service. The processing of this flowchart is executed during the operation of the remote operation system (1).

[0099] Steps S100 and S102:

[0100] In step S100, the management device (30) (processor (33)) waits for a request for a remote operation service from the service provider system (40). While there is no request for a remote operation service (step S102; "No"), the management device (30) maintains a waiting state. Meanwhile, if a request for a remote operation service is received while waiting (step S102; "Yes"), the management device (30) continues to wait for other requests for remote operation services while executing the processing after step S104 in parallel.

[0101] Step S104:

[0102] In step S104, the management device (30) receives request information (REQ) from the operator system (40). As previously described, the request information (REQ) includes information such as the type of remote operation service and the level of urgency.

[0103] Step S106:

[0104] Next, in step S106, the management device (30) reads and updates the management information (MNG) stored in the memory device (34). Specifically, for example, the management information (MNG) includes various information included in the request information (REQ) (type of remote operation service, urgency, etc.), the difficulty level (D) described above, the priority of response to the request, information of the candidate operator (4) (e.g., past operation record, qualifications, and waiting information), and information of the remote operation device (20) (e.g., information indicating a suitable mobile body (10), and waiting information). The priority of response is determined based on, for example, the type of remote operation service, urgency, and difficulty level (D).

[0105] In step S106, the management device (30) calculates (sets) the difficulty (D) of the remote operation regarding the current request information (REQ) received in step S104 using the following method. Then, the management device (30) updates the response priority of each remote operation request currently included in the management information (MNG) by taking into account the calculated difficulty (D).

[0106] (Method for calculating difficulty (D))

[0107] The above-described difficulty (D) can be calculated as follows based on various information included in the request information (REQ) transmitted from the operator system (40), for example. That is, in this example, the difficulty (D) is calculated by multiplying a predetermined basic value (e.g., 1.0) by a coefficient Ki (i=1 to n) corresponding to each of the various information (e.g., urgency, type of remote operation service, type of mobile body (10), completion condition, movement route, and presence or absence of a designated time). That is, each coefficient Ki represents the difficulty (Di) in individual information units such as urgency. For example, each coefficient Ki is set to a reference value (e.g., 1.0) when the difficulty (Di) is standard. And, each coefficient Ki is set to a value smaller than the reference value (e.g., 0.8) when the difficulty (Di) is lower than the standard difficulty, and on the other hand, is set to a value larger than the reference value (e.g., 1.5) when the difficulty (Di) is higher than the standard difficulty. The relationship between each coefficient Ki and the difficulty (Di) of individual information, such as urgency, is determined in advance and stored in a memory device (34). The management device (30) obtains each coefficient Ki corresponding to various information included in the current request information (REQ) from the above relationship. For example, if the urgency included in the current request information (REQ) is "high," the management device (30) obtains the urgency coefficient K1 corresponding to the "high" urgency from the above relationship.

[0108] Additionally, each coefficient Ki of the difficulty level (D) calculated as described above may be modified (optimized) based on the evaluation result of the difficulty level by the remote operator (2) who actually performed the remote operation. Specifically, whenever the remote operation is terminated, the management device (30) obtains the evaluation result of the difficulty level of this remote operation (e.g., easy, normal, or difficult) from the remote operator (2) through the remote operation device (20). The management device (30) stores the obtained evaluation result in the memory device (34) in relation to the difficulty level (set difficulty) D set in the remote operation in step S106. In this way, the relationship between the evaluation result and the set difficulty level (D) is accumulated. Then, the management device (30) determines the discrepancy of the evaluation result with respect to the set difficulty level (D) based on the accumulated information, and if the discrepancy is acknowledged, executes a process to statistically optimize each coefficient Ki so that the discrepancy is reduced.

[0109] Additionally, each coefficient Ki of the difficulty (D) may be modified (optimized) in the same way, on behalf of or together with the evaluation result of the remote operator (2), for example, based on at least one of “time required for remote operation” and “number of troubles in remote operation.” Specifically, in the example where time required for remote operation is used, the management device (30) stores the actual time required for remote operation in relation to the estimated value of the time required for the remote operation in the memory device (34) whenever the remote operation ends. In this way, the relationship between the actual time required and the estimated value is accumulated. Then, based on the accumulated information, the management device (30) determines whether the actual time required is excessively long relative to the estimated value, and if the actual time required is excessively long, performs a process to statistically optimize each coefficient Ki so that the time difference is shortened. Likewise, in the example where the number of troubles in remote operation is used, the management device (30) stores the number of troubles in the memory device (34) whenever the remote operation ends. Accordingly, the number of trouble occurrences is accumulated. Then, the management device (30) determines whether the number of trouble occurrences is excessive based on the accumulated information, and if the number of trouble occurrences is excessive, performs a process to statistically optimize each coefficient Ki so that the number of trouble occurrences decreases.

[0110] Step S108:

[0111] Next, in step S108, the management device (30) selects a remote operation device (20) to be used for remote operation regarding this request information (REQ). Specifically, the management device (30) selects a remote operation device (20) based on information included in, for example, the management information (MNG) (e.g., the type of remote operation service and the response priority).

[0112] Steps S110 and S112:

[0113] Next, in step S110, the management device (30) performs a process to check whether there is a spare in the selected remote operation device (20). As a result, if there is no spare (step S110; "No"), the process proceeds to step S112. In step S112, the management device (30) updates the management information (MNG) so that the selected remote operation device (20) is in a standby state. After that, the processing of steps S108 and S110 is repeated.

[0114] Step S114:

[0115] Meanwhile, if there is a surplus in the selected remote operation device (20) (Step S110; "Yes"), the process proceeds to Step S114. In Step S114, the management device (30) selects a candidate operator (4) for remote operation regarding the current request information (REQ). Specifically, the management device (30) selects a candidate operator (4) based on information included in, for example, the management information (MNG) (e.g., the type of remote operation service and the response priority).

[0116] Steps S116 and S118:

[0117] Next, in step S116, the management device (30) performs a process to check whether there is a surplus for the selected candidate operator (4). As a result, if there is no surplus (step S116; "No"), the process proceeds to step S118. In step S118, the management device (30) updates the management information (MNG) so that the selected candidate operator (4) is in a waiting state. After that, the processing of steps S114 and S116 is repeated.

[0118] Step S120:

[0119] Meanwhile, if there is a surplus of selected candidate operators (4) (Step S116; "Yes"), the processing proceeds to Step S120. In Step S120, the management device (30) generates presentation information (PST) using the method already described.

[0120] Step S122:

[0121] Next, in step S122, the management device (30) notifies the selected candidate operator (4) of the generated presentation information (PST). In the example where the candidate operator (4) is waiting at the waiting place (5), the presentation information (PST) is notified via the display device (50). In this example, the presentation information (PST) may include information specifying the candidate operator (4) to be notified. Additionally, if the candidate operator (4) possesses a mobile terminal (60), the presentation information (PST) may be notified via the display device (50).

[0122] (Example of processing on the information providing device side)

[0123] More specifically, in step S122, the management device (30) transmits the presentation information (PST) to an "information providing device," such as a display device (50), in order to notify the candidate operator (4) of the presentation information (PST). The information providing device acquires (receives) the presentation information (PST). Then, the information providing device notifies the candidate operator (4) of the acquired presentation information (PST) by displaying it on a display, etc. Thus, according to the flowchart shown in FIG. 6, the information providing device acquires the presentation information (PST) before the remote operator (2) performing this remote operation is determined in step S126 described later, and also notifies the candidate operator (4) of the presentation information (PST) before said determination.

[0124] (Examples of different notifications depending on urgency)

[0125] Additionally, in step S122, the management device (30) may transmit the presentation information (PST) accompanied by instructions to display the presentation information (PST) in different forms depending on the urgency included in the presentation information (PST). Alternatively, the management device (30) may transmit the presentation information (PST) accompanied by instructions to notify the presentation information (PST) accompanied by different sounds depending on the urgency. Alternatively, the management device (30) may transmit the presentation information (PST) accompanied by both of these instructions.

[0126] The information providing device that receives instructions as described above notifies the presentation information (PST) accompanied by at least one of different displays and sounds according to the level of urgency. For example, when the presentation information (PST) is displayed as shown in FIG. 5, the information providing device may display the presentation information (PST) in a manner that makes it easier to identify a request for remote operation with a level of urgency greater than a predetermined level compared to other requests. Additionally, for example, when notifying a request for remote operation with a level of urgency greater than a predetermined level, the information providing device may notify the presentation information (PST) accompanied by a sound that draws the attention of the candidate operator (4) compared to when notifying other requests. This also applies to the transmission of the presentation information (PST) by processing step S126 described later.

[0127] Step S124:

[0128] Next, in step S124, the management device (30) performs a process to confirm with the candidate operator (4) whether it is possible to respond to the request for this remote operation. The candidate operator (4) operates a specific device, such as a mobile terminal (60), and responds to the management device (30) regarding whether to accept the request.

[0129] According to the processing of steps S122 and S124, the candidate operator (4) may have the opportunity to determine whether to accept the request for this remote operation by checking the notified presentation information (PST) before the remote operator (2) makes a decision. Additionally, the candidate operator (4) may refuse to accept the request.

[0130] If the candidate operator (4) is not capable of responding (Step S124; "No"), the process returns to Step S114. That is, another candidate operator (4) is selected. Meanwhile, if the candidate operator (4) is capable of responding (Step S124; "Yes"), the process proceeds to Step S126.

[0131] Step S126:

[0132] In step S126, the management device (30) performs a process to determine a candidate operator (4) currently selected as the remote operator (2) who performs the remote operation regarding this request. Then, the management device (30) transmits presentation information (PST) to the remote operation device (20) that is scheduled to be used by the determined remote operator (2). The presentation information (PST) transmitted to the remote operation device (20) is displayed, for example, using a display (25). Alternatively, the presentation information (PST) may be notified by voice through a speaker (26) instead of displaying it on the display (25), or together with it.

[0133] Step S128:

[0134] Next, in step S128, the management device (30) performs a process to determine whether the determined remote operator (2) is ready to start this remote operation. For example, if the determined remote operator (2) operates the switch of the remote operation device (20) used this time and gives a response indicating that the preparation is complete, the management device (30) determines that the preparation is complete.

[0135] Step S130:

[0136] When the remote operator (2) is ready (step S128; "Yes"), the management device (30) initiates remote operation by the remote operator (2) (step S130). Specifically, the management device (30) initiates the generation of remote operation information (OPE) of the remote operation device (20) by the remote operator (2), and the transmission of the generated remote operation information (OPE) to the mobile body (10).

[0137] Steps S132 and S134:

[0138] Next, in step S132, the management device (30) determines whether the current remote operation has ended. In other words, the management device (30) determines whether the completion condition described above has been satisfied. As a result, if the remote operation has not ended (step S132; "No"), the process proceeds to step S134. In step S134, the management device (30) updates the management information (MNG) as needed. For example, the management device (30) updates information indicating the state (current state) of the mobile body (10) during the remote operation execution.

[0139] Meanwhile, if the remote operation is terminated (step S132; "Yes"), the process returns to step S100.

[0140] 5. Effects

[0141] As described above, according to the "information providing device" of the present embodiment, before a remote operator (2) who accepts a request for remote operation from a mobile body (10) is determined, presentation information (PST) indicating the content of the request is notified to one or more candidate operators (4). By doing so, the candidate operators (4) can accept the request for remote operation with confidence.

[0142] More specifically, by notifying the presentation information (PST) before the remote operator (2) is determined, the candidate operator (4) can be given the opportunity to decide whether to accept the request based on the presentation information (PST). Furthermore, for example, if the information notified before the remote operator (2) is determined is merely a request notification asking to accept the request, the candidate operator (4) lacks the material to decide whether to accept the request. As a result, for example, the candidate operator (4) may be required to decide whether to accept the request while feeling anxious about the possibility of accepting a request that was not originally intended in order to obtain the opportunity for remote operation. In contrast, the presentation information (PST) in this embodiment is information that specifically indicates the content of the request for remote operation. Because of this, the candidate operator (4) can decide whether to accept the request with peace of mind.

[0143] In addition, in the example of the remote operation system (1) shown in FIG. 1, the remote operation targets multiple types of mobile bodies (10). Because of this, if proper consideration is not given to the request for remote operation to the candidate operator (4), the candidate operator (4) may feel great anxiety about the possibility of accepting a request for remote operation of an unintended type of mobile body (10). Furthermore, the more types of mobile bodies (10) there are, the higher the anxiety of the candidate operator (4) may be. In this regard, the presentation information (PST) regarding this embodiment includes "information indicating the type of mobile body (10)." By doing so, even when performing remote operation targeting multiple types of mobile bodies (10), the candidate operator (4) can make a decision with greater confidence regarding whether to accept the request.

[0144] In addition, in the example of the remote operation system (1) shown in FIG. 1, there are multiple types of remote operation services provided. Because of this, if proper consideration is not given to the request for remote operation to the candidate operator (4), the candidate operator (4) may feel great anxiety about the possibility of accepting a request for a remote operation service of an unintended type. Furthermore, the more types of remote operation services there are, the higher the anxiety of the candidate operator (4) may be. In this regard, the presentation information (PST) regarding this embodiment includes "information indicating the types of remote operation services." By doing so, even when performing remote operation targeting multiple types of mobile bodies (10), the candidate operator (4) can make a decision with greater confidence regarding whether to accept the request.

[0145] In addition, according to an example where the presentation information (PST) includes both information indicating the type of mobile body (10) and information indicating the type of remote operation service, the “information providing device” can present to the candidate operator (4) in a very easy-to-understand manner what remote operation is required for which remote operation service, depending on the type of mobile body (10) and remote operation service.

[0146] In addition, the presentation information (PST) regarding the present embodiment includes "information indicating the state of the mobile body (10) at the time of the request," "information on the urgency of the remote operation," "information on the qualifications required of the remote operator (2)," "information on the conditions for the completion of the remote operation," and "information on the difficulty of the remote operation." By including at least one of these various types of information, the presentation information (PST) can be presented to the candidate operator (4) in an easy-to-understand manner as to what kind of remote operation is required.

[0147] In addition, in this embodiment, the presentation information (PST) is notified accompanied by at least one of different indicators and sounds depending on the level of urgency. Accordingly, for example, when encountering multiple presentation information (PST) at the same time, the candidate operator (4) can make a judgment to prioritize accepting requests with a higher level of urgency. Furthermore, the candidate operator (4) can be made aware of accepting requests with a higher level of urgency.

[0148] In addition, in this embodiment, the presentation information (PST) is also notified to the remote operation device (20) that is scheduled to be operated by the remote operator (2) to perform remote operation based on the request. The presentation information (PST) is information that helps not only the candidate operator (4) decide whether to accept the request, but also to perform remote operation after accepting the request. Because of this, the candidate operator (4) determined as the remote operator (2) can, for example, move from the waiting area (5), sit in the remote cockpit (remote operation device (20)), and then quickly start remote operation while checking the presentation information (PST).

[0149] Additionally, the content of the presentation information (PST) required by the candidate operator (4) may vary depending on the proficiency of the candidate operator (4). Therefore, in this embodiment, the presentation information (PST) includes different content depending on the proficiency of the candidate operator (4) regarding remote operation. By doing so, presentation information (PST) suitable for each individual candidate operator (4) can be notified more accurately.

[0150] In addition, in this embodiment, the "information providing device" is, for example, a display device (50) placed in a waiting area (5). By this, presentation information (PST) can be notified to one or more candidate operators (4) who are waiting in the waiting area (5) before being determined as the remote operator (2). In addition, the "information providing device" is, for example, a portable terminal (60) held by the candidate operator (4) who is waiting. By this, presentation information (PST) can be notified to the candidate operator (4) who is waiting before being determined as the remote operator (2).

[0151] 6. Other various configuration examples of the remote operation system

[0152] In the remote control system (1), the type of mobile body (10) that is the target of remote control may be only one.

[0153] In addition, the type of remote operation service provided to one or more types of mobile bodies (10) may be one.

[0154] Additionally, the remote operation system does not need to be equipped with a service provider system (40). In the example of a remote operation system that does not have a service provider system (40), the request information (REQ) may be transmitted directly from the mobile body (10) to the management device (30).

[0155] In addition, in the example of the flowchart shown in FIG. 6, the management device (30) selects one candidate operator (4) and notifies the selected candidate operator (4) of presentation information (PST) (see steps S114 and S122). Then, if the candidate operator (4) does not accept the request for remote operation, the next candidate operator (4) is selected (see steps S124 and S114). Alternatively, the management device (30) may notify multiple candidate operators (4) of one presentation information (PST) simultaneously. And, if multiple candidate operators (4) wish to accept the request, the management device (30) may execute a process to determine one candidate operator (4) among multiple applicants as the remote operator (2), for example, based on management information (MNG).
