The operation of the task management device 20 according to the present embodiment will be described with reference to
In step S101, the control unit 21 of the task management device 20 detects deterioration of the internal environment of the vehicle 30 as the environmental deterioration during the period P1 in which the vehicle 30 is operated in the first mode M1. Specifically, the environmental deterioration is detected by either or both of the following procedures.
In a first procedure, the vehicle 30 captures an image of the inside of the vehicle 30 using a camera mounted on the vehicle 30 during the period P1. The vehicle 30 transmits the captured image to the task management device 20 via a communication interface that is mounted on the vehicle 30 and is compatible with mobile communication standards such as LTE, the 4G standard, or the 5G standard, V2X communication standards such as DSRC or cellular V2X, or wireless LAN communication standards such as IEEE 802.11.

The term “DSRC” is an abbreviation for “dedicated short range communications”. The term “V2X” is an abbreviation for “vehicle-to-everything”.
The control unit 21 of the task management device 20 receives the image of the inside of the vehicle 30 from the vehicle 30 via the communication unit 23. The control unit 21 detects dirt inside the vehicle 30 as the environmental deterioration by analyzing the received image. As a method of image analysis, a known method can be used. Machine learning such as deep learning may be used.
In a second procedure, the vehicle 30 measures the odor inside of the vehicle 30 using a sensor mounted on the vehicle 30 during the period P1. The vehicle 30 transmits the obtained measurement results to the task management device 20 via the communication interface mounted on vehicle 30.
The control unit 21 of the task management device 20 receives the measurement result of the odor of the vehicle 30 from the vehicle 30 via the communication unit 23. The control unit 21 detects dirt inside the vehicle 30 as the environmental deterioration with reference to the received measurement result.
In step S102, the control unit 21 of the task management device 20 calculates the time required for the maintenance of the internal environment of the vehicle in accordance with the environmental deterioration detected in step S101, and determines whether the maintenance is completed by the mode switching time limit Tm. The mode switching time limit Tm is a time line for switching the mode of the vehicle 30 to the second mode M2 that is different from the first mode M1. It is assumed that the mode switching time limit Tm is set in advance. Whether the maintenance is completed by the mode switching time limit Tm is specifically determined by the following procedure.
When the control unit 21 of the task management device 20 detects the dirt inside the vehicle 30 as the environmental deterioration in step S101, the control unit 21 calculates the time required for a cleaning staff member or a cleaning robot on board the vehicle 30 to clean the inside of the vehicle 30 as the time required for the maintenance. More specifically, the control unit 21 derives the cleaning time corresponding to parameters such as the amount or the type of dirt inside the vehicle 30 detected in step S101 as the time required for the maintenance with reference to a conversion table stored in the storage unit 22 in advance or using a predefined conversion formula.
When the odor inside the vehicle 30 is detected as the environmental deterioration in step S101, the control unit 21 of the task management device 20 calculates the time required for an air purifier mounted on the vehicle 30 to perform deodorizing inside the vehicle 30 as the time required for the maintenance. More specifically, the control unit 21 derives the operation time of the air purifier corresponding to parameters such as the intensity or the type of odor inside the vehicle 30 detected in step S101 as the time required for the maintenance with reference to a conversion table stored in the storage unit 22 in advance or using a predefined conversion formula.
The control unit 21 of the task management device 20 compares the calculated time required for the maintenance time with the remaining time until the mode switching time limit Tm. When the time required for the maintenance is shorter than the remaining time, the control unit 21 determines that the maintenance is completed by the mode switching time limit Tm. When the time required for the maintenance is the same as the remaining time, the control unit 21 may also determine that the maintenance is completed by the mode switching time limit Tm. When the time required for the maintenance is longer than the remaining time, the control unit 21 determines that the maintenance is not completed by the mode switching time limit Tm.
When the control unit 21 determines in step S102 that the maintenance is completed by the mode switching time limit Tm, the process in step S103 is executed. When the control unit 21 determines in step S102 that the maintenance is not completed by the mode switching time limit Tm, the process in step S105 is executed.
In step S103, the control unit 21 of the task management device 20 waits until the mode switching time limit Tm is reached or the use of the vehicle 30 in the first mode M1 is completed. When the mode switching time limit Tm is reached, the process in step S104 is executed. When the use of the vehicle 30 in the first mode M1 is completed even before the mode switching time limit Tm, the process in step S104 is executed.
In step S104, the control unit 21 of the task management device 20 executes the mode switching control C1 as the operational control Ci in accordance with the determination result obtained in step S102. The mode switching control C1 is control for switching the mode of the vehicle 30 to the second mode M2.
Specifically, the control unit 21 of the task management device 20 transmits first instruction data Di1 for instructing the operator to change the interior or the exterior of the vehicle 30 to the interior or the exterior corresponding to the second mode M2 to the terminal device of the operator, such as a mobile phone, a smart phone, or a tablet, via the communication unit 23, thereby executing the mode switching control C1. Upon receipt of the first instruction data Di1, the terminal device of the operator displays the received first instruction data Di1 on the display or outputs the received first instruction data Di1 by voice from the speaker. The operator changes the interior or the exterior of the vehicle 30 in accordance with the first instruction data Di1 displayed or output by voice. For example, the operator installs rear seats for bus passengers to be seated or moves rear seats to specific positions. Alternatively, the operator may cause a display provided as part of the exterior of the vehicle 30 to display operation information such as the destination of the bus.
When the vehicle 30 has a function of automatically changing the interior or the exterior of the vehicle 30, the control unit 21 of the task management device 20 may execute the mode switching control C1 by transmitting a second instruction data Di2 for instructing the vehicle 30 to change the interior or the exterior of the vehicle 30 to the interior or the exterior corresponding to the second mode M2 to the vehicle 30 via the communication unit 23, instead of or in addition to transmission of the first instruction data Di1 to the terminal device of the operator. In such a modification, the vehicle 30 receives the second instruction data Di2 from the task management device 20 via the communication interface mounted on vehicle 30. The vehicle 30 changes the interior or the exterior of the vehicle 30 in accordance with the received second instruction data Di2. For example, the vehicle 30 moves rear seats for the bus passengers to be seated to the specific positions. Alternatively, the vehicle 30 may display the operation information such as the destination of the bus on a display provided as part of the exterior of the vehicle 30.
In step S105, the control unit 21 of the task management device 20 waits until the mode switching time limit Tm is reached or the use of the vehicle 30 in the first mode M1 is completed. When the mode switching time limit Tm is reached, the process in step S106 is executed. When the use of the vehicle 30 in the first mode M1 is completed even before the mode switching time limit Tm, the process in step S106 is executed.
In step S106, the control unit 21 of the task management device 20 executes the vehicle introduction control C2 as the operational control Ci in accordance with the determination result obtained in step S102. The vehicle introduction control C2 is control for introducing an alternative vehicle operated in the second mode M2.
Specifically, the control unit 21 of the task management device 20 executes the vehicle introduction control C2 by transmitting third instruction data Di3 that instructs the alternative vehicle to transport the passengers that are supposed to be transported during a period P2 during which the vehicle 30 is scheduled to be operated in the second mode M2 after the period P1 to the alternative vehicle via the communication unit 23. When the mode of the alternative vehicle is switched by changing the interior, the exterior, or both in the same manner as the vehicle 30, the third instruction data Di3 may include data that instructs a change of the interior or the exterior of the alternative vehicle to the interior or the exterior corresponding to the second mode M2. Upon receipt of the third instruction data Di3, the alternative vehicle transports the passengers in accordance with the received third instruction data Di3.
As described above, in the present embodiment, when the vehicle 30 is operated for distribution purposes, the time required for detecting the environmental deterioration such as dirt inside the vehicle 30 and improving the environment such as removal of the dirt inside the vehicle 30 is calculated, whereby another vehicle can be dispatched as a bus when the required time is long. In other words, it is possible to perform a flexible operation in accordance with the time required to improve the internal environment of the vehicle 30.
A modification of the operation of the task management device 20 according to the present embodiment will be described with reference to
The processes in steps S111 and S112 are the same as the processes in steps S101 and S102 in
When the control unit 21 determines in step S112 that the maintenance is completed by the mode switching time limit Tm, the process in step S113 is executed. When the control unit 21 determines in step S112 that the maintenance is not completed by the mode switching time limit Tm, the process in step S115 is executed.
The processes in steps S113 and S114 are the same as the processes in steps S103 and S104 in
In step S115, the control unit 21 of the task management device 20 determines whether to execute the vehicle introduction control C2 in accordance with the environmental deterioration detected in step S111. Whether to execute the vehicle introduction control C2 is specifically determined by the following procedure.
The control unit 21 of the task management device 20 determines whether the environmental deterioration detected in step S111 is acceptable with reference to tolerance data Da that is stored in the storage unit 22 in advance. The tolerance data Da is data indicating tolerance for deterioration of the internal environment of the vehicle 30 for the application in the second mode M2. Such data can be, for example, a correspondence table that defines corresponding tolerance for each application such as delivery of articles, transportation of passengers, or sale of products. In this correspondence table, the tolerance corresponding to delivery of articles may be defined higher than the tolerance corresponding to sale of products. The tolerance corresponding to the sale of products may be defined higher than the tolerance corresponding to the transportation of passengers. The applications may be subdivided, with corresponding tolerances defined for each subdivision. The tolerance is expressed, for example, by the amount of dirt that is allowable or the intensity of odor that is allowable.
The tolerance data Da may be data indicating the tolerance for deterioration of the internal environment of the vehicle 30 for targets to be transported in the second mode M2. For such data, for example, the correspondence table that defines tolerances corresponding to articles such as luggage delivered by the vehicle 30, products such as bread sold by the vehicle 30, or passengers transported by the vehicle 30 can be used. In this correspondence table, the tolerance corresponding to the articles delivered by the vehicle 30 may be defined higher than the tolerance corresponding to the products sold by the vehicle 30. The tolerance corresponding to the products sold by the vehicle 30 may be defined higher than the tolerance corresponding to the passengers transported by the vehicle 30. The target objects may be subdivided, with corresponding tolerances defined for each subdivision.
When the control unit 21 of the task management device 20 determines that the environmental deterioration detected in step S111 is allowable, the control unit 21 determines not to execute the vehicle introduction control C2. When the control unit 21 determines that the environmental deterioration detected in step S111 is not allowable, the control unit 21 determines to execute the vehicle introduction control C2.
When a determination is made in step S115 that the vehicle introduction control C2 is not executed, the process in step S113 is executed. When a determination is made in step S115 that the vehicle introduction control C2 is executed, the process in step S116 is executed.
The processes in steps S116 and S117 are the same as the processes in steps S105 and S106 in
As described above, in the example shown in
Another modification of the operation of the task management device 20 according to the present embodiment will be described with reference to
The processes in steps S121 and S122 are the same as the processes in steps S101 and S102 in
When the control unit 21 determines in step S122 that the maintenance is completed by the mode switching time limit Tm, the process in step S123 is executed. When the control unit 21 determines in step S122 that the maintenance is not completed by the mode switching time limit Tm, the process in step S125 is executed.
The processes in steps S123 and S124 are the same as the processes in steps S103 and S104 in
In step S125, the control unit 21 of the task management device 20 changes the switching destination mode of the mode switching control C1 from the second mode M2 to the third mode M3 corresponding to the application in accordance with the environmental deterioration detected in step S121. Specifically, the switching destination mode is changed in the following procedure.
The control unit 21 of the task management device 20 determines in which mode the environmental deterioration detected in step S121 is acceptable with reference to the tolerance data Da that is stored in the storage unit 22 in advance. Since the tolerance data Da is the same as that referred to in step S115 of
When the control unit 21 of the task management device 20 determines that the environmental deterioration detected in step S121 is allowable in the mode corresponding to the delivery of the articles, the control unit 21 selects the mode corresponding to the delivery of the articles as the third mode M3. When the control unit 21 determines that the environmental deterioration detected in step S121 is allowable in the mode corresponding to the sale of the products, the control unit 21 selects the mode corresponding to the sale of the products as the third mode M3. When the control unit 21 determines that the environmental deterioration detected in step S121 is allowable in two or more modes, the control unit 21 may select an arbitrary mode from among the two or more modes as the third mode M3, or may select any one of the modes as the third mode M3 in accordance with a certain priority. The control unit 21 changes the switching destination mode of the mode switching control C1 to the selected third mode M3. When the control unit 21 determines that the environmental deterioration detected in step S121 is allowable in the second mode M2, it is not necessary to change the switching destination mode of the mode switching control C1.
After step S125, the processes in steps S123 and S124 are executed. When the switching destination mode of the mode switching control C1 is changed to the third mode M3 in step S125, in step S124, the control unit 21 of the task management device 20 executes the mode switching control C1 to switch the vehicle 30 to the third mode M3, instead of the second mode M2.
Specifically, the control unit 21 of the task management device 20 executes the mode switching control C1 by transmitting the fourth instruction data Di4 for instructing the operator to change the interior or the exterior of the vehicle 30 to the interior or the exterior corresponding to the third mode M3 to the terminal device of the operator via the communication unit 23. Upon receipt of the fourth instruction data Di4, the terminal device of the operator displays the received fourth instruction data Di4 on the display or outputs the received fourth instruction data Di4 by voice from the speaker. The operator changes the interior or the exterior of the vehicle 30 in accordance with the fourth instruction data Di4 displayed or output by voice.
When the vehicle 30 has a function of automatically changing the interior or the exterior of the vehicle 30, the control unit 21 of the task management device 20 may execute the mode switching control C1 by transmitting a fifth instruction data Di5 for instructing the vehicle 30 to change the interior or the exterior of the vehicle 30 to the interior or the exterior corresponding to the third mode M3 to the vehicle 30 via the communication unit 23, instead of or in addition to transmission of the fourth instruction data Di4 to the terminal device of the operator. In such a modification, the vehicle 30 receives the fifth instruction data Di5 from the task management device 20 via the communication interface mounted on vehicle 30. The vehicle 30 changes the interior or the exterior of the vehicle 30 in accordance with the received fifth instruction data Di5.
As described above, in the example shown in

When the control unit 21 determines in step S132 that the maintenance is not completed by the mode switching time limit Tm, the process in step S135 is executed.
The processes in steps S133 and S134 are the same as the processes in steps S103 and S104 in
In step S135, the control unit 21 of the task management device 20 transmits notification data Dn for notifying the user 11 of the environmental deterioration detected in step S131 to the terminal device 40 via the communication unit 23. The notification data Dn is specifically transmitted in the following procedure.
