In other words, flexible operation according to the time required to prepare the internal environment of the vehicle 30 becomes possible.

[0022] The configuration of a task management device 20 according to this embodiment will be described with reference to FIG.

[0023] The task management device 20 includes a control unit 21, a storage unit 22, and a communication unit 23.

[0024] The control unit 21 includes at least one processor, at least one programmable circuit, at least one dedicated circuit, or any combination thereof.

The storage unit 22 stores data used in the operation of the task management device 20 and data obtained by the operation of the task management device 20.

[0026] The communication unit 23 includes at least one communication interface. The communication interface is, for example, an interface compatible with a wired LAN communication standard such as Ethernet (registered trademark), or an interface compatible with a wireless LAN communication standard such as IEEE802.11. "IEEE" is an abbreviation for Institute of Electrical and Electronics Engineers. The communication unit 23 communicates with the vehicle 30. The communication unit 23 receives data used in the operation of the task management device 20, and transmits data obtained by the operation of the task management device 20.

[0027] The functions of task management device 20 are realized by executing a program according to this embodiment on a processor serving as control unit 21. That is, the functions of task management device 20 are realized by software. The program causes a computer to execute the operations of task management device 20, thereby causing the computer to function as task management device 20. That is, the computer functions as task management device 20 by executing the operations of task management device 20 in accordance with the program.

[0028] The program may be stored in a non-transitory computer-readable medium. Examples of the non-transitory computer-readable medium include a flash memory, a magnetic recording device, an optical disk, a magneto-optical recording medium, or a ROM.

Then, the computer reads the program stored in the main storage device with a processor, and executes processing according to the read program with the processor. The computer may read the program directly from a portable medium and execute processing according to the program. The computer may execute processing according to the received program each time a program is transferred from the server to the computer.

"ASP" is an abbreviation for application service provider. A program is information used for processing by a computer, and includes those equivalent to a program. For example, data that is not a direct command to a computer but has the property of defining computer processing falls under "those equivalent to a program."

[0030] A part or all of the functions of the task management device 20 may be realized by a programmable circuit or a dedicated circuit as the control unit 21. In other words, a part or all of the functions of the task management device 20 may be realized by hardware.

[0031] The operation of the task management device 20 according to this embodiment will be described with reference to Fig. 3. This operation corresponds to the task management method according to this embodiment.

[0032] In step S101, the control unit 21 of the task management device 20 refers to the deterioration degree data Dd to estimate the degree of deterioration of the internal environment of the vehicle 30 caused by transporting the first object B1. The deterioration degree data Dd is data that defines the degree of deterioration of the internal environment of the vehicle 30 caused by transporting each of two or more types of objects for each type of object. As such data, for example, a correspondence table that defines the corresponding deterioration degree for each type of object, such as goods delivered by the vehicle 30, goods sold by the vehicle 30, or passengers transported by the vehicle 30, can be used. In this correspondence table, the deterioration degree corresponding to goods or goods that emit an odor, such as fresh fish or meat, may be defined higher than the deterioration degree corresponding to goods or goods that do not emit an odor, such as boxed luggage. The deterioration degree corresponding to passengers who are likely to soil the inside of the vehicle, such as children, may be defined higher than the deterioration degree corresponding to passengers who are unlikely to soil the inside of the vehicle, such as adults. The deterioration degree is expressed, for example, by the amount of dirt or the strength of the odor. The deterioration level data Dd is stored in advance in the storage unit 22 of the task management device 20 or in an external storage. The first object B1 is an object transported by the vehicle 30 in the first mode M1.

[0033] A specific procedure of the process in step S101 is shown in FIG.

[0034] In step S111, the control unit 21 of the task management device 20 waits until the type of the first object B1 is detected during the period P1 in which the vehicle 30 is operated in the first mode M1. Specifically, the type of the first object B1 is detected by the following procedure.

[0035] During the period P1, the vehicle 30 captures an image of the inside of the vehicle 30 using a camera mounted on the vehicle 30. The vehicle 30 transmits the captured image to the task management device 20 via a communication interface implemented in the vehicle 30 and compatible with a mobile communication standard such as LTE, 4G standard, or 5G standard, a V2X communication standard such as DSRC or cellular V2X, or a wireless LAN communication standard such as IEEE802.11. "LTE" is an abbreviation for Long Term Evolution. "4G" is an abbreviation for 4th generation. "5G" is an abbreviation for 5th generation. "DSRC" is an abbreviation for dedicated short range communications. "V2X" is an abbreviation for vehicle-to-everything.

[0036] The control unit 21 of the task management device 20 receives an image of the interior of the vehicle 30 from the vehicle 30 via the communication unit 23. The control unit 21 detects the type of the first object B1 by analyzing the received image. A known method can be used as a method of image analysis. Machine learning such as deep learning may also be used.

[0037] When the type of the first object B1 is detected, the process of step S112 is executed. If the type of the first object B1 is not detected during the period P1, the procedure shown in FIG.

[0038] In step S112, the control unit 21 of the task management device 20 estimates the degree of deterioration of the internal environment of the vehicle 30 caused by transporting the first object B1 by identifying the degree of deterioration defined in the deterioration degree data Dd for the type of the first object B1. For example, if the use corresponding to the first mode M1 is delivery of goods or sale of goods, when the control unit 21 detects an item or product that emits an odor, such as fresh fish or meat, in step S111, the control unit 21 estimates the degree of deterioration represented by the intensity of the odor of the internal environment of the vehicle 30 to be higher than when the control unit 21 detects an item or product that does not emit an odor, such as a boxed baggage, in step S111. If the use corresponding to the first mode M1 is transportation of passengers, when the control unit 21 detects a passenger who is likely to soil the interior of the vehicle, such as a child, in step S111, the control unit 21 estimates the degree of deterioration represented by the amount of dirt in the internal environment of the vehicle 30 to be higher than when the control unit 21 detects a passenger who is unlikely to soil the interior of the vehicle, such as an adult, in step S111.

[0039] In step S102, the control unit 21 of the task management device 20 calculates the time required for maintenance of the internal environment of the vehicle 30 before switching the vehicle 30 from the first mode M1 to the second mode M2, based on the estimation result obtained for the first object B1 in step S101. Specifically, the time required for maintenance is calculated by the following procedure.

[0040] When the control unit 21 of the task management device 20 estimates the degree of dirt inside the vehicle 30 as the deterioration level in step S101, the control unit 21 calculates the time required for the cleaning staff or cleaning robot aboard the vehicle 30 to clean the inside of the vehicle 30 as the required time for maintenance. More specifically, the control unit 21 derives the cleaning time corresponding to the degree of dirt inside the vehicle 30 estimated in step S101 as the required time for maintenance by referring to a conversion table pre-stored in the storage unit 22 or by using a pre-defined conversion formula. The derived cleaning time becomes longer as the estimated dirtiness inside the vehicle 30 increases, i.e., the deterioration level increases.

[0041] When the control unit 21 of the task management device 20 estimates the strength of the odor inside the vehicle 30 as the degree of deterioration in step S101, it calculates the time it takes for the air purifier mounted on the vehicle 30 to remove the odor inside the vehicle 30 as the required time for maintenance. More specifically, the control unit 21 derives, as the required time for maintenance, the operating time of the air purifier corresponding to the odor strength inside the vehicle 30 estimated in step S101, by referring to a conversion table pre-stored in the storage unit 22 or by using a pre-defined conversion formula. The derived operating time becomes longer as the estimated odor inside the vehicle 30 becomes stronger, i.e., the degree of deterioration becomes higher.

[0042] If the control unit 21 of the task management device 20 is unable to estimate the deterioration level in step S101, the control unit 21 may use a preset default value as the calculated value of the time required for maintenance.

[0043] In step S103, the control unit 21 of the task management device 20 adjusts the dispatch schedule of the vehicle 30 according to the required time calculated in step S102. The adjustment of the dispatch schedule of the vehicle 30 includes adjustment of the time at which the vehicle 30 is switched to the second mode M2 ​​and adjustment of the time at which the vehicle 30 starts to be operated in the second mode M2. For example, if the required time for maintenance is long, the control unit 21 delays the time at which the vehicle 30 is switched to the second mode M2. The control unit 21 also delays the time at which the vehicle 30 starts to be operated in the second mode M2. If the required time for maintenance is short, the control unit 21 does not change or advances the time at which the vehicle 30 is switched to the second mode M2. The control unit 21 also does not change or advances the time at which the vehicle 30 starts to be operated in the second mode M2.

[0044] Specifically, first, the control unit 21 of the task management device 20 transmits the first instruction data Di1, which instructs the worker to change the interior or exterior of the vehicle 30 to the interior or exterior corresponding to the second mode M2, to the worker's terminal device such as a mobile phone, smartphone, or tablet via the communication unit 23. The first instruction data Di1 includes data specifying a time. When the worker's terminal device receives the first instruction data Di1, it displays the received first instruction data Di1 on a display or outputs it by voice from a speaker. The worker changes the interior or exterior of the vehicle 30 at the specified time according to the first instruction data Di1 displayed or output by voice. For example, if the use corresponding to the second mode M2 ​​is a bus, the worker installs a rear seat for the bus passengers to sit on or moves the rear seat to a specific position. Alternatively, the worker may display operation information such as the destination of the bus on a display equipped on the vehicle 30 as part of the exterior.

[0045] In the case where the vehicle 30 has a function of automatically changing the interior or exterior of the vehicle 30, the control unit 21 of the task management device 20 may transmit, instead of or in addition to transmitting the first instruction data Di1 to the terminal device of the worker, to the vehicle 30 via the communication unit 23, second instruction data Di2 that instructs the vehicle 30 to change the interior or exterior of the vehicle 30 to the interior or exterior corresponding to the second mode M2. In such a modified example, the second instruction data Di2 includes data specifying a time. The vehicle 30 receives the second instruction data Di2 from the task management device 20 via a communication interface implemented in the vehicle 30. The vehicle 30 changes the interior or exterior of the vehicle 30 at a specified time according to the received second instruction data Di2. For example, if the use corresponding to the second mode M2 ​​is a bus, the vehicle 30 moves the rear seat for the passengers to sit in to a specific position. Alternatively, the vehicle 30 may display operation information such as the destination of the bus on a display equipped as part of the exterior of the vehicle 30.

[0046] Next, the control unit 21 of the task management device 20 transmits third instruction data Di3 to the vehicle 30 via the communication unit 23, the third instruction data Di3 instructing the vehicle 30 to start operating in the second mode M2 ​​of the vehicle 30. The third instruction data Di3 includes data specifying a time. The vehicle 30 receives the third instruction data Di3 from the task management device 20 via a communication interface implemented in the vehicle 30. The vehicle 30 starts moving at a specified time according to the received third instruction data Di3. For example, if the use corresponding to the second mode M2 ​​is a bus, the vehicle 30 departs for a location where passengers are to be picked up first.

[0047] As described above, in this embodiment, when the vehicle 30 is operated for logistics purposes, the degree of environmental deterioration such as odor inside the vehicle 30 is estimated according to the characteristics of the transported goods, the time required for environmental improvement such as removing the odor inside the vehicle 30 is calculated, and the time to switch the vehicle 30 to a bus and start operating it can be adjusted depending on whether it takes time. Similarly, in this embodiment, when the vehicle 30 is operated as a bus, the degree of environmental deterioration such as dirt inside the vehicle 30 is estimated according to the characteristics of the person transporting the goods, the time required for environmental improvement such as removing the dirt inside the vehicle 30 is calculated, and the time to switch the vehicle 30 to a logistics purpose and start operating it can be adjusted depending on whether it takes time. That is, flexible operation according to the time required for environmental improvement inside the vehicle 30 is possible. When the vehicle 30 is a BEV, the timing of charging the vehicle 30 and the timing of environmental improvement inside the vehicle 30 may be synchronized.

[0048] A modified example of the operation of the task management device 20 according to the present embodiment will be described with reference to FIG.

[0049] In step S201, the control unit 21 of the task management device 20 refers to the tolerance data Da to estimate the degree of deterioration of the internal environment of the vehicle 30 that is permitted when transporting the second object B2. The tolerance data Da is data that defines the degree of deterioration of the internal environment of the vehicle 30 that is permitted when transporting each of two or more types of objects for each type of object. As such data, for example, a correspondence table that defines the corresponding tolerance for each type of object, such as an object delivered by the vehicle 30, a product sold by the vehicle 30, or a passenger transported by the vehicle 30, can be used. In this correspondence table, the tolerance corresponding to the object or product may be defined to be higher than the tolerance corresponding to the passenger. The tolerance is expressed, for example, by the amount of dirt or the strength of the odor. The tolerance data Da is stored in advance in the storage unit 22 of the task management device 20 or an external storage. The second object B2 is an object transported by the vehicle 30 in the second mode M2.

[0050] FIG. 6 shows a specific procedure of the process in step S201.

[0051] In step S211, the control unit 21 of the task management device 20 waits until the type of the second target B2 is notified to the task management device 20 before the period P2 during which the vehicle 30 is operated in the second mode M2. The type of the second target B2 may be notified to the task management device 20 at any timing and in any manner, such as being transmitted as part of data input by the user when the user reserves the use of the vehicle 30 when the vehicle 30 is operated in the second mode M2. Instead of directly notifying the task management device 20 of the type of the second target B2, the task management device 20 may be indirectly notified of the type of the second target B2 by notifying the task management device 20 of the use corresponding to the second mode M2. For example, if the use corresponding to the second mode M2 ​​is the delivery of goods, it is at least known that the type of the second target B2 is goods. If the use corresponding to the second mode M2 ​​is the sale of goods, it is at least known that the type of the second target B2 is goods. If the use corresponding to the second mode M2 ​​is the transportation of passengers, it is at least known that the type of the second target B2 is passengers. When the type of the second target B2 is notified to the task management device 20, the process of step S212 is executed. If the type of the second target B2 is notified to the task management device 20 before the period P2, the procedure shown in FIG. 6 ends.

[0052] In step S212, the control unit 21 of the task management device 20 estimates the degree of deterioration of the internal environment of the vehicle 30 that is tolerable when transporting the second object B2 by identifying the degree of deterioration defined in the tolerance data Da for the type of the second object B2. For example, when the control unit 21 is notified in step S211 that the use corresponding to the second mode M2 ​​is delivery of goods or sale of merchandise, the control unit 21 estimates the tolerance, represented by the degree of dirtiness or the strength of odor, of the internal environment of the vehicle 30 to be higher than when the control unit 21 is notified in step S211 that the use corresponding to the second mode M2 ​​is transportation of passengers.

[0053] In step S202, the control unit 21 of the task management device 20 calculates the time required for maintenance of the internal environment of the vehicle 30 before switching the vehicle 30 from the first mode M1 to the second mode M2, based on the estimation result obtained for the second object B2 in step S201. Specifically, the time required for maintenance is calculated by the following procedure.

[0054] When the control unit 21 of the task management device 20 estimates the degree of dirtiness inside the vehicle 30 as the tolerance in step S201, the control unit 21 calculates the time required for the cleaning staff or cleaning robot aboard the vehicle 30 to clean the inside of the vehicle 30 as the required time for maintenance. More specifically, the control unit 21 derives the cleaning time corresponding to the degree of dirtiness inside the vehicle 30 estimated in step S201 as the required time for maintenance by referring to a conversion table pre-stored in the storage unit 22 or by using a pre-defined conversion formula. The derived cleaning time becomes longer as the allowable degree of dirtiness inside the vehicle 30 decreases, i.e., as the tolerance decreases.

[0055] When the control unit 21 of the task management device 20 estimates the strength of the odor inside the vehicle 30 as the tolerance in step S201, it calculates the time it takes for the air purifier mounted on the vehicle 30 to remove the odor inside the vehicle 30 as the required time for maintenance. More specifically, the control unit 21 derives the operating time of the air purifier corresponding to the odor strength inside the vehicle 30 estimated in step S201 as the required time for maintenance by referring to a conversion table pre-stored in the storage unit 22 or by using a pre-defined conversion formula. The derived operating time becomes longer as the allowable odor inside the vehicle 30 becomes weaker, i.e., the tolerance becomes lower.

[0056] If the control unit 21 of the task management device 20 is unable to estimate the tolerance in step S201, the control unit 21 may use a preset default value as the calculated value of the time required for maintenance.

[0057] The process of step S203 is similar to the process of step S103 in FIG. 3, and therefore the description thereof will be omitted.

[0058] 5, when vehicle 30 is operated for a certain purpose, the tolerable degree of environmental deterioration, such as dirt inside vehicle 30, is estimated depending on what is to be transported, the time required to improve the environment, such as removing the dirt inside vehicle 30, is calculated, and the time at which vehicle 30 starts to be operated for that purpose can be adjusted depending on whether or not the time is required. In other words, flexible operation according to the time required to improve the environment inside vehicle 30 is possible.

[0059] As a modified example of this embodiment, the process of step S201 in Fig. 5 may be added to the operation shown in Fig. 3. That is, in step S102, the control unit 21 of the task management device 20 may calculate a required time for maintenance of the internal environment of the vehicle 30 before switching the vehicle 30 from the first mode M1 to the second mode M2, based on both the estimation result obtained in step S101 for the first object B1 and the estimation result obtained in step S201 for the second object B2.

[0060] As a modified example of this embodiment, at least one vehicle 30 may be a plurality of vehicles moving on a common route or within a common area. The control unit 21 of the task management device 20 may adjust the dispatch schedule of the plurality of vehicles to operate two or more vehicles in different modes in the same period. The control unit 21 may adjust the dispatch schedule of the plurality of vehicles 30 to operate two or more vehicles in the same mode in different periods. For example, it may be determined when, in which mode, and for how long the plurality of vehicles are operated so that there is a difference between the vehicles. In other words, for each vehicle, a time frame for operation for logistics purposes, a time frame for cleaning the interior of the vehicle, and a time frame for operation as a bus may be set with a slight lag.
