Summary of the Invention

Problems to be Solved by the Invention

[0005] However, remote support is not necessarily required at that support point at the predicted timing. If support does not occur, losses occur in the operation of the ensured operator, and a situation where there is no vacancy occurs. Further, for example, if a new support request occurs at a timing when there is no vacancy for the operator, the start of support is delayed.

[0006] The present disclosure has been made in view of the above circumstances, and an object thereof is to provide a remote support device and a remote support program that enable smooth operation by remote support.

Means for Solving the Problems

[0007] The remote support device (100) according to the present disclosure includes a prediction unit (120) that predicts a support occurrence probability associated with the support content of the location information and a priority when support is required, based on a travel route including a support location and the location information of the support location; and a reservation unit (122) that determines whether reservation of support by an operator is necessary based on the support occurrence probability and the priority, and sets a reservation for support so that, when reservation is necessary, even if a support request with a low priority newly occurs during the reservation, the support task is not assigned to the operator.

Advantages of the Invention

[0008] According to the remote support device and the remote support program of the present disclosure, it is possible to enable smooth operation by remote support.

Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0011] The outline of the embodiment of the present disclosure will be described. In this embodiment, in order to solve the above problems, a reservation for operator support is set. The remote support device, which is an automatic driving center, calculates and stores location information such as the support content, support time, and occurrence frequency of remote support at support points on the driving route, and based on the location information, predicts the priority and support occurrence probability of remote support. Then, operator support is reserved according to the prediction result. During the reservation, even if a support request with a low priority newly occurs, the support task is not assigned to the operator. As a result, the start of support is not delayed for highly necessary support requests, so safety is improved and smooth vehicle operation becomes possible.

[0012] A typical example of a reservation will be described. FIG. 1 is a diagram illustrating a case of responding to a support request when a reservation is set. Regarding whether a support reservation is possible, there are cases where (1) makes a reservation and (2) does not make a reservation. For (1), since it is predicted that support with a medium priority will occur from vehicle V1 with a high probability (support occurrence probability), it is assumed that a reservation is made. For (2), since it is predicted that support with a medium priority will occur from vehicle V1 with a low probability, it is assumed that no reservation is made. Next, after determining whether to make a reservation in the above (1) and (2), when a new support request occurs, the response can be divided into cases A, B, and C. Case A is when support with a low priority occurs from vehicle V2 in (1). In this case, since the priority of the reservation is higher than the priority of the support that has occurred, the support for vehicle V2 is postponed (case (1)-A). Case B is when support with a high priority occurs from vehicle V2 in (1). In this case, since the priority of the support that has occurred is higher than the priority of the reservation, the support for vehicle V2 is carried out, and the reservation for vehicle V1 is changed or canceled (case (1)-B). Case C is when support with a low priority occurs from vehicle V2 in (2). In this case, since no reservation has been made, the support for vehicle V2 is carried out (case (2)-C). In this way, the reservation controls whether other support tasks can interrupt.

[0013] The above is the outline of the method according to this embodiment. Hereinafter, the configuration and operation of this embodiment will be described.

[0014] [Configuration of the Automatic Driving System] FIG. 2 is a block diagram showing the configuration of the automatic driving system 10 according to an embodiment of the present disclosure. As shown in FIG. 2, the automatic driving system 10 includes a plurality of vehicles 80, an operator terminal 90 operated by an operator, and a remote support device 100 connected via a network N. Note that the configurations of the vehicle 80 and the operator terminal 90 may be the same as those in the general method of remote support for vehicles in Patent Document 1 and the like, so the specific configurations are omitted.

[0015] FIG. 3 is a block diagram showing the hardware configuration of the remote support device 100. As shown in FIG. 3, the remote support device 100 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a storage 14, an input unit 15, a display interface (I / F) 16, and a communication interface (I / F) 17. Each component is connected to be communicable with each other via a bus 19.

[0016] The CPU 11 is a central processing unit that executes various programs including a remote support program and controls each unit. That is, the CPU 11 reads a program from the ROM 12 or the storage 14 and executes the program using the RAM 13 as a work area. The CPU 11 performs control of each of the above components and various arithmetic processes according to the programs stored in the ROM 12 or the storage 14. In the present embodiment, a remote support program is stored in the ROM 12 or the storage 14.

[0017] The ROM 12 stores various programs and various data. The RAM 13 temporarily stores a program or data as a work area. The storage 14 is composed of a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and stores various programs including an operating system and various data.

[0018] The input unit 15 includes a pointing device such as a mouse and a keyboard, and is used to perform various inputs.

[0019] The display interface 16 is, for example, a liquid crystal display and displays various information. The display interface 16 may adopt a touch panel method and function as the input unit 15.

[0020] The communication interface 17 is an interface for communicating with other devices such as terminals. For example, standards such as Ethernet (registered trademark), FDDI, Wi-Fi (registered trademark), Bluetooth (registered trademark), and cellular communication systems are used. The above is an explanation of an example of the hardware configuration of the remote support device 100.

[0021] Hereinafter, the functional configuration of the remote support device 100 will be described.

[0022] The remote support device 100 includes an autonomous driving information storage unit 102, a location information storage unit 104, a reservation information storage unit 106, a communication unit 110, a remote control unit 112, a prediction unit 120, and a reservation unit 122.

[0023] The autonomous driving information storage unit 102 stores vehicle information related to remote support of the vehicle, route plans (driving routes), driving plans, operator information, support task information, and the like.

[0024] The location information storage unit 104 stores location information for each support location. The location information includes support content, support time, service target time, etc. for each location. The support content is associated with a support occurrence probability and a priority. The support occurrence probability is based on probability reference information including past statistical information, and the probability reference information includes support logs of other vehicles. The support log is information such as the support content and support time performed at that location. The priority is set to levels 1 to 4 for each support content, for example, with the highest priority being level 1 at the highest level and the lowest priority being level 4 at the lowest level. The highest level is an example of a high level above a predetermined level of the present disclosure, and the lowest level is an example of a low level below a predetermined level of the present disclosure. Note that the support occurrence probability is the probability that support is required, and the priority is the importance when support is required. An example of an increase in the support occurrence probability will be described. For example, in the case of a right-turn support at an intersection where an oncoming vehicle is approaching and the predicted trajectory of the vehicle entering the intersection overlaps with the predicted trajectory of the own vehicle, the support occurrence probability is set high. Also, in the case of overtaking support, on a road with many vehicles waiting to enter a warehouse or parked on the roadside, the support occurrence probability is set high. Also, in the case of a bus stop departure support (in-vehicle safety check), when there are passengers getting on and off, the support occurrence probability is set high. Thus, information such as the situation of a support location that is not statistical information is also used for determining the necessity of a reservation.

[0025] The reservation information storage unit 106 stores reservation information (reservation frame and reservation period) set by the reservation unit 122. Also, the reservation information storage unit 106 stores a setting (for example, a threshold) of a criterion corresponding to the support occurrence probability and priority for determining the necessity of a reservation. The application example of the criterion will be described in the reservation unit 122.

[0026] The communication unit 110 communicates with the vehicle 80 and the operator terminal 90 via the network N and transmits and receives necessary information.

[0027] The remote control unit 112 performs all controls related to remote support. The controls related to remote support include route planning of the vehicle 80, creation of driving plans, and assignment of support tasks to the operator, etc. Note that for route planning, not only can it be performed by the remote control unit 112, but also the following three functional arrangements are assumed. (1) It is arranged in the remote support device 100 or other devices in the automatic driving system 10. (2) It is arranged in the cooperating operation management system. (3) It is arranged in the cooperating vehicle. In the cases of (2) and (3) above, the automatic driving system 10 does not perform route planning, but has a functional arrangement for acquiring route planning information. Note that for other various functions, since they may be the same as those in Patent Document 1 etc., specific descriptions are omitted.

[0028] The prediction unit 120 predicts the support occurrence probability that vehicle support is required, which is associated with the support content of the location information, and the priority when support is required. The prediction is performed, for example, based on the driving route including the support location and the location information related to the support location. The prediction can be implemented, for example, by referring to the location information of each support location and the statistical information on the driving route, and obtaining the support occurrence probability and priority for each support content. For example, by referring to the past statistical information etc. in the automatic driving information storage unit 102, extracting the "assumed support content" on the driving route, and predicting the support occurrence probability and priority of the support content. Note that when the support occurrence probability changes according to time, the arrival scheduled time to the support location in the driving plan can be used to estimate the support occurrence probability according to time.

[0029] The reservation unit 122 determines whether a reservation for operator support is necessary based on the support occurrence probability and the priority, and sets a reservation for support. The criteria stored in the reservation information storage unit 106 are used for determining whether a reservation is necessary. Below, specific examples of the reservation process, the reservation period, and the determination of whether a reservation is necessary are explained respectively.

[0030] The reservation period will be described. The reservation by the reservation unit 122 is made, for example, at the time of the operation plan of the vehicle 80. After referring to the table of support occurrence probability and priority, and the threshold value, and determining whether reservation of support is necessary, if it is determined to make a reservation, the reservation period is set. FIG. 4 is a diagram showing an example of setting the reservation period. Regarding the reservation period (operator support frame reservation period), in the upper part of FIG. 4 (1) when considering the support time of other tasks (that is, when including the waiting time until the start of reservation), in the lower part of FIG. 4 (2) when not considering the support time of other tasks. It is assumed that the reservation period sets the support time associated with the support content with the estimated support start scheduled time (min) estimated from the scheduled arrival time as the reference for the start point (or an arbitrary position up to max may be used as the reference for the start point).

[0031] In the example of FIG. 4, an example of reservation update when support for another support task newly occurs will be described. For the reserved support in (1) of FIG. 4, when the priority of the occurred support of other tasks is the same or higher, the reservation content is changed from the reserved support to the occurred support. This is because even when the priorities are the same, it is assumed that what is certain to require support should take precedence over what may require support. The reserved support makes a reservation change at the time after the end of the occurred support or cancels the reservation. Also, when the estimated end time of the occurred support is shorter than the estimated start time of the reserved support, the start time of the reservation period is changed to the estimated end time of the occurred support. In the case of (2) of FIG. 4, it is confirmed whether there is reserved support whose estimated end time of the occurred support of other tasks overlaps with the reservation period. If there is overlapping reserved support and the priority of the occurred support is the same or higher for the reserved support, the reservation content is changed from the reserved support to the occurred support. The reserved support makes a reservation change at the time after the end of the occurred support or cancels the reservation. If there is no reserved support whose estimated end time of the occurred support overlaps with the reservation period, no reservation update is performed. This is because it is considered that it does not affect the reserved support, and it is sufficient to handle in the order of occurred support → reserved support.

[0032] Specific examples of reservation necessity determination will be described. FIG. 5 is an example of a reservation necessity determination table related to support occurrence probability and priority. In FIG. 5, in addition to priority, support content, and support occurrence probability, the support execution probability is shown as the SLO (Service Level Objective) of availability. The support execution probability is a requirement for a predetermined service level. Examples of options for the specific reservation necessity determination method include the criteria (1) to (4). Thresholds may be determined appropriately for each criterion. (1) If the combination of priority and support occurrence probability exceeds the threshold, reservation is possible. (2) Calculate the operator reservation frame that satisfies the support execution probability. The reservation frame is set to one frame per operator, and the allocation during the period is managed for the entire reservation process. It can be calculated how many operators should be allocated from the support occurrence probability and the reservation frame to satisfy the support execution probability. (3) When the priority is low to high (except for the highest or lowest), reservation is possible when the total support occurrence probability is greater than the reservation frame. For example, if the support occurrence probability is 30%, up to three support tasks can be set in one reservation frame. (4) When the priority is low to high, reservation is possible according to the support occurrence probability. For example, if the support occurrence probability is 30%, the reservation frame +1 is set with a probability of 0.3. Details of (1) and (2) will be described below.

[0033] The case of using the threshold of the combination in (1) will be described. FIG. 6 is a table representing the threshold of the combination based on rules. The left side of FIG. 6 is the determination criterion for the necessity of reservation considering priority and support occurrence probability, and the right side of FIG. 6 is the determination criterion for the necessity of reservation considering priority, support occurrence probability, and service target time. In the case of the right side of FIG. 6, for example, when the priority is 2 and the support occurrence probability is 0.2, it is determined that reservation is required, and when the priority is 2 and the support occurrence probability is 0.1, it is determined that reservation is not required, which is defined as the determination criterion. The left side of FIG. 6 is the case where the service target time is defined for the support content. For example, for the support content with a priority of 3, a support occurrence probability of 0.5, and a service target time of 10 s, it is determined that reservation is required, and for the support content with a service target time of 60 s, it is determined that reservation is not required. In this way, the allowable length of the waiting time is determined by the service target time. It can be said that the shorter the service target time, the higher the importance, the higher the necessity of reservation, and the longer the service target time, the lower the importance and the lower the assumption of urgency. Therefore, even if the priority and support occurrence probability are the same, the necessity of reservation is made different. The case of (1) shown in FIG. 6 corresponds to the typical example of reservation described in FIG. 1.

[0034] The support execution probability in (2) will be described. For example, the support execution probability may be obtained and determined based on this. The SLO of availability is set to 100% in any of the following (note that it is not 100% for the entire operation time). [1] Support occurrence candidates including non-occurrence of support, and [2] the number of support executions after the occurrence of support. [1] is calculated from the operator's perspective (considering the wasted effort when support does not occur), and [2] is calculated from the vehicle's perspective.

[0035] FIG. 7 shows a calculation example of the support execution probability. The case of calculating the operator reservation frame that satisfies the support execution probability will be described. The example of FIG. 7 is a case where it is expected that three tasks with medium priority levels will occur. The probability for each number of support occurrences is obtained using the support occurrence probability. The probability that the number of support occurrences is 3 is the lowest at 0.001, and the probability that the number of support occurrences is 0 is the highest at 0.729. The support execution probability is obtained from this probability and the fulfillment rate of the operator reservation frame with respect to the number of support occurrences. Since the requirement for the support execution probability with medium priority in FIG. 5 is 90%, it can be seen that the support execution probability can be satisfied by reserving one frame of the operator whether or not support occurs.

[0036] Next, the operation of the remote support device 100 will be described. FIG. 8 is a flowchart showing the reservation process according to the embodiment of the present disclosure. The CPU 11 functions as each part of the remote support device 100 and executes the reservation process. The reservation process is to be executed at the time of the operation plan of the vehicle 80, and it is assumed that the travel route has been acquired.

[0037] In step S100, the CPU 11 acquires the location information of the support location on the travel route.

[0038] In step S102, the CPU 11 predicts the support occurrence probability that vehicle support is required, which is associated with the support content of the location information, and the priority level when support is required. The prediction is made based on the travel route including the support location and the location information related to the support location. Thereby, the support occurrence probability and the priority level of the support location are predicted.

[0039] In step S104, the CPU 11 determines whether reservation of support is necessary based on the predicted support occurrence probability and the priority level. Details of the determination process will be described later.

[0040] In step S106, if the CPU 11 determines in step S104 that reservation is necessary, it proceeds to step S108, and if it determines that reservation is not necessary, the process ends.

[0041] In step S108, the reservation period for operator assistance is set. Regarding the reservation period, it can be arbitrarily set whether to consider the assistance time of other tasks. After the reservation process, if other assistance tasks that have occurred occur, the above-mentioned reservation update may be performed. The reservation update may be changed or canceled by moving the reservation period. The determination of the change may be made according to the priority and the assistance occurrence probability as described with reference to FIG. 1 above. Also, if no assistance task has occurred during a certain period, the reservation may be canceled.

[0042] Next, the details of the determination of the necessity of reservation in step S104 will be described. Since the cases of the criteria (1) to (4) described in the above criteria can be applied to the determination of the necessity of reservation, each will be described. Note that since (3) and (4) can be the same determination routine for the necessity of reservation, only (3) will be described. The determination routine for the necessity of reservation may be performed in descending order of priority for each assistance content of the vehicle 80.

[0043] FIG. 9 is a determination routine for the necessity of reservation based on the threshold values of the combination of priority and assistance occurrence probability.

[0044] In step S200, the CPU 11 determines whether the priority is equal to or higher than the threshold value. If the priority is equal to or higher than the threshold value, the process proceeds to step S206, and if the priority is not equal to or higher than the threshold value, the process proceeds to step S202. In the present embodiment, the threshold value of the priority is set to be level 1 or higher, which is the highest level.

[0045] In step S202, the CPU 11 refers to the reservation necessity determination table using the assistance occurrence probability and priority predicted in step S102. This is the table illustrated in FIG. 5. When the assistance content includes the service target time, the service target time is also used.

[0046] In step S204, the CPU 11 determines whether the corresponding record in the reservation necessity determination table requires reservation. If reservation is required, the process proceeds to step S206, and if reservation is not required, the process ends.

[0047] In step S206, the CPU 11 allocates a reservation frame for the operator. The information of the reservation frame is stored in the reservation information storage unit 106.

[0048] FIG. 10 is a determination processing routine for calculating an operator reservation frame that satisfies the support execution probability.

[0049] In step S210, the CPU 11 determines whether the priority is equal to or higher than a threshold value. If the priority is equal to or higher than the threshold value, the process proceeds to step S218. If the priority is lower than the threshold value, the process proceeds to step S212.

[0050] In step S212, the CPU 11 acquires the information of the reservation frame for the current period based on the scheduled arrival time.

[0051] In step S214, the CPU 11 calculates the required reservation frame based on the support occurrence probability and the support execution probability. As shown in the example shown in FIG. 7, the required reservation frame may be calculated.

[0052] In step S216, the CPU 11 determines whether the required reservation frame is larger than the current reservation frame. If the reservation frame is larger, the process proceeds to step S218. If the reservation frame is not larger, the process ends.

[0053] In step S218, the CPU 11 allocates the reservation frame for the current period of the operator as +1. The information of the reservation frame is stored in the reservation information storage unit 106. By performing the determination process of reservation necessity for each support content, it is possible to comprehensively determine the required reservation frame for the support execution probability. Also, an appropriate reservation frame that is assumed to be necessary is allocated at the support location.

[0054] In addition, in the determination of step S216, the reservation frame can also be reduced in consideration of the service target time. FIG. 11 shows an example of a case where the reservation frame is reduced by delaying the support start timing by the amount of the service target time. For taskA (assumed support content), since the service target time is long, the reservation frame can be reduced by shifting the corresponding period. Without the service target time, up to three tasks need to be supported simultaneously, which may result in waiting time. However, with the service target time, it can be reduced to up to two tasks being supported simultaneously, reducing the risk of waiting time.

[0055] FIG. 12 shows a determination processing routine when the total support occurrence probability is greater than the reservation frame.

[0056] In step S220, the CPU 11 determines whether the priority is equal to or higher than the threshold value. If the priority is equal to or higher than the threshold value, the process proceeds to step S226. If the priority is not equal to or higher than the threshold value, the process proceeds to step S222.

[0057] In step S222, the CPU 11 acquires the information of the reservation frame for the corresponding period based on the scheduled arrival time.

[0058] In step S224, the CPU 11 adds the support occurrence probability for the corresponding period.

[0059] In step S226, the CPU 11 determines whether the cumulative occurrence probability after addition is greater than the probability of the reservation frame (the probability of the reservation frame is 1) for the corresponding period. If the cumulative occurrence probability is greater, the process proceeds to step S228. If the cumulative occurrence probability is not greater, the process ends.

[0060] In step S228, the CPU 11 assigns the reservation frame of the operator for the corresponding period as +1. The information of the reservation frame is stored in the reservation information storage unit 106. By performing the determination process of whether reservation is required for each support content, it is possible to comprehensively determine the necessary reservation frame for the support occurrence probability. Also, at the support location, an appropriate reservation frame assumed to be necessary is assigned.

[0061] As described above, according to the remote support device 100 related to the automatic driving system 10 of the embodiment of the present disclosure, smooth operation by remote support can be enabled.

[0062] Note that the present disclosure is not limited to the above-described embodiments, and various modifications and applications are possible without departing from the gist of the invention.

[0063] For example, when the driving plan is changed, such as when a change occurs in the driving route or the scheduled arrival time, the reservation may be updated. When the driving route is changed, the support location and the support occurrence probability also change. Therefore, when the driving route is changed, the reservation availability determination result and the reservation period are updated. Thereby, the prediction accuracy of the reservation availability determination and the reservation period is improved, and it is possible to reduce the delay in the start of support due to the occurrence of a new support request at a timing when there is no availability for the operator, and the operation loss of the secured operator. When a change occurs in the scheduled arrival time due to a change in the driving plan or due to the influence of surrounding traffic, etc., the scheduled support start time changes. Therefore, when a change in the scheduled arrival time is detected, the prediction accuracy can be improved by updating the reservation period. In addition, since the accuracy of the scheduled arrival time improves as the vehicle approaches the support location, the estimated accuracy of the reservation period may be increased by periodically updating the reservation, and the reservation frame may be calculated more accurately.

[0064] Also, in the present specification, although the embodiment in which the program is pre-installed has been described, it is also possible to store the program in a computer-readable recording medium and provide it.
