Here, the task information is one or more of the following: passenger number information indicating the number of passengers, passenger characteristic information indicating the characteristics of the passengers, baggage type information indicating the type of baggage to be loaded, destination information indicating the destination, and usage purpose information indicating the usage purpose of the user.

[0031] The map information storage unit 204d stores map information including the route conditions of each of the multiple routes. Here, the map information is map data used by each of the vehicles 101 to 10n during autonomous driving based on the position information of the vehicle itself. The route conditions are one or more of the road width, gradient, noise level of the surrounding environment, and roughness. Here, the roughness is a value based on the result of tallying up the amount of change in gravity in the vertical direction detected by the sensor group 105 of the vehicles 101 to 10n.

[0032] The control unit 205 is configured using a memory and a processor having hardware such as a CPU. The control unit 205 controls the operation of each unit constituting the management server 20. The control unit 205 has an acquisition unit 205a, an allocation unit 205b, a decision unit 205c, a setting unit 205d, a display control unit 205e, a communication control unit 205f, a determination unit 205g, and a drive control unit 205h. In one embodiment, the control unit 205 functions as a processor.

[0033] The acquisition unit 205a acquires vehicle specification information from the vehicle specification information storage unit 204b, task information including a plurality of tasks on a specified date specified by the operator from the task information storage unit 204c, and map information including the route status of each of a plurality of routes from the map information storage unit 204d.

[0034] The allocation unit 205b allocates the vehicle 10 based on the vehicle specification information and task information acquired by the acquisition unit 205a. 1 ~Vehicle 10 n For example, when a task involves transporting fragile items such as glass, fruits, valuables, or electronic equipment, the allocation unit 205b generates allocation information that allocates a vehicle 10 with high vibration damping properties based on the vehicle specification information.

[0035] The determination unit 205c determines whether or not the vehicle 10 is located on the basis of the allocation information generated by the allocation unit 205b and the map information acquired by the acquisition unit 205a. 1 ~Vehicle 10 n For example, in the case of a vehicle 10 with high vibration damping assigned with a task of transporting fragile items such as glass, fruits, valuables, or cargo such as electronic equipment, when there are multiple routes to the destination, the determination unit 205c generates the driving route information by determining the route with the least bumps and grooves based on the route conditions included in the map information, excluding places with gradients where the bottom of the vehicle 10 scrapes against the ground. Also, the determination unit 205c generates the driving route information by determining the route with the least bumps and grooves based on the driving route information. 1 ~Vehicle 10 nFor each of the above, the system generates driving route information including an overtaking point for allowing a following vehicle to proceed when a traffic jam occurs on the driving route. Here, the overtaking point is at least one of a straight road having a predetermined road width and a place where the target vehicle can leave the driving route and make a temporary stop. The place where the target vehicle can make a temporary stop is, for example, a bus stop or a parking lot where passengers board when the vehicle 10 travels along the driving route.

[0036] The setting unit 205d determines whether the vehicle 10 is traveling on the road based on the allocation information generated by the allocation unit 205b, the map information acquired by the acquisition unit 205a, and the driving route information generated by the determination unit 205c. 1 ~Vehicle 10 n The controller 10 generates speed information that sets the speed at which each of the vehicles travels.

[0037] The display control unit 205e outputs to the display unit 202 the allocation information generated by the allocation unit 205b, the driving route information generated by the determination unit 205c, and the speed information generated by the setting unit 205d.

[0038] The communication control unit 205f transmits, via the communication unit 201, the allocation information generated by the allocation unit 205b, the driving route information generated by the determination unit 205c, and the speed information generated by the setting unit 205d to the vehicle 10. 1 ~Vehicle 10 n The output is sent to each of the following.

[0039] The determination unit 205g determines whether the vehicle 10 1 ~Vehicle 10 n Based on the position information of each of the vehicles 10, the determination unit 205g determines whether or not a traffic jam has occurred on a predetermined travel route. 1 ~Vehicle 10 n Based on the position information of each of the vehicles 10 within a predetermined area (for example, 100 m x 100 m), 1 ~Vehicle 10 n The density of vehicles is calculated, and it is determined whether or not this density is equal to or greater than a threshold value. If the density is equal to or greater than the threshold value, it is determined that a traffic jam is occurring on a predetermined travel route.

[0040] The drive control unit 205h instructs the target vehicle, which is in a traffic jam on the predetermined travel route determined by the determination unit 205g to be in a traffic jam, to move to an overtaking point. Specifically, the drive control unit 205h instructs the target vehicle to move to the overtaking point and stop temporarily for a predetermined time via the communication unit 201. In addition, after a following vehicle following the target vehicle has overtaken the target vehicle, the drive control unit 205h stops the target vehicle at the overtaking point until a predetermined time has elapsed or the distance between the following vehicle and the target vehicle becomes a predetermined distance. Furthermore, the drive control unit 205h acquires the number of passengers of the target vehicle via the communication unit 201, and when the target vehicle is stopped at the overtaking point and the number of passengers of the target vehicle exceeds half of the capacity of the target vehicle, the drive control unit 205h opens an openable door of the target vehicle.

[0041] [Management Server Processing] Next, a description will be given of the processing executed by the management server 20. FIG 3 is a flowchart showing an outline of the processing executed by the management server 20.

[0042] As shown in FIG. 3, first, the acquisition unit 205a acquires vehicle specification information from the vehicle specification information storage unit 204b, task information including a plurality of tasks for a specified date specified by the operator via the input unit 203 from the task information storage unit 204c, and map information from the map information storage unit 204d (step S101).

[0043] Next, the allocation unit 205b assigns the vehicle 10 to the vehicle 10 based on the vehicle specification information and task information acquired by the acquisition unit 205a. 1 ~Vehicle 10 nThe allocation unit 205b generates allocation information in which each of the above is assigned to a plurality of tasks (step S102). For example, when the task is to transport fragile items such as glass, fruits, valuables, or electronic equipment, the allocation unit 205b generates allocation information in which the vehicle 10 with high vibration damping is assigned based on the vehicle specification information. When the task is to transport athletes for the Olympics or the like, the allocation unit 205b generates allocation information in which the large vehicle 10 is assigned based on the vehicle specification information. When the task is to transport a large number of people, the allocation unit 205b generates allocation information in which the large vehicle 10 is assigned based on the vehicle specification information. When the task is to transport a large number of people, the allocation unit 205b generates allocation information in which the large vehicle 10 is assigned based on the vehicle specification information. When the task is to transport a large number of people, the allocation unit 205b generates allocation information in which the large vehicle 10 is assigned based on the vehicle specification information. When the task is to transport people staying overnight, the allocation unit 205b generates allocation information in which the large vehicle 10 is assigned based on the vehicle specification information. Furthermore, when the task is to pick up or drop off a guest, the allocation unit 205b generates allocation information that allocates a luxury vehicle 10. The allocation unit 205b allocates a vehicle 10 according to the task based on the vehicle specification information, excluding a vehicle 10 under maintenance.

[0044] Thereafter, the determination unit 205c determines whether or not the vehicle 10 is to be parked on the basis of the allocation information generated by the allocation unit 205b and the map information acquired by the acquisition unit 205a. 1 ~Vehicle 10 nThe determination unit 205c generates driving route information that determines the route along which each of the vehicles 10 will travel (step S103). For example, in the case of a vehicle 10 with high vibration damping properties that is assigned a task of transporting fragile items such as glass, fruits, valuables, or luggage such as electronic devices, when there are multiple driving routes to the destination, the determination unit 205c generates the driving route information by selecting a driving route with the least bumps and grooves, excluding places with gradients where the bottom of the vehicle 10 rubs against the ground, based on the route state included in the map information. In addition, in the case of a large vehicle 10 that is assigned a task of transporting athletes, when there are multiple driving routes to the destination, the determination unit 205c generates the driving route information by selecting a driving route, excluding places where the vehicle body protrudes more than expected when the vehicle 10 turns right or left, based on the route state included in the map information. Specifically, the determination unit 205c calculates the expected turning radius R when turning right or left, based on the minimum turning radius included in the vehicle specification information of the large vehicle 10 that is assigned a task of transporting athletes and the road width of the route state included in the map information. The determination unit 205c then determines whether the turning radius R is equal to or greater than a preset threshold, and generates driving route information by excluding routes with turning radius R equal to or greater than the threshold from among the multiple driving routes. In addition, in the case of a vehicle 10 that is assigned a task of transporting people staying overnight, when there are multiple routes to the destination, the determination unit 205c generates driving route information by selecting a route in ascending order of noise level based on the route conditions included in the map information. Furthermore, the determination unit 205c generates driving route information by selecting a route in ascending order of noise level from the route conditions included in the map information for the vehicle 10 based on the driving route information. 1 ~Vehicle 10 n For each of the above, driving route information is generated including overtaking points for allowing a following vehicle to proceed ahead when congestion occurs on the driving route.

[0045] Next, the setting unit 205d determines whether the vehicle 10 is to be driven based on the allocation information generated by the allocation unit 205b, the map information acquired by the acquisition unit 205a, and the route information generated by the determination unit 205c. 1 ~Vehicle 10 nThen, the speed information is generated by setting the speed at which each of the above travels (step S104). For example, in the case of a vehicle 10 with high vibration damping properties that is assigned the task of transporting fragile items such as glass, fruits, valuables, electronic equipment, or other cargo, when a travel route to the destination that has many bumps is determined, the speed information is generated by setting a slower speed based on the route state included in the map information so that the vehicle 10 does not vibrate up and down at places with a slope where the bottom of the vehicle 10 rubs against the ground.

[0046] Next, the display control unit 205e outputs the assignment information, the route information, and the speed information to the display unit 202 (step S105). This allows the operator managing the management system 1 to grasp the tasks, the travel routes, and the speeds of each vehicle 10 on the designated date designated via the input unit 203.

[0047] After that, the communication control unit 205f transmits the vehicle 10 1 ~Vehicle 10 n The vehicle 10 outputs the allocation information, the route information, and the speed information to each of the vehicles 10 (step S106). 1 ~Vehicle 10 n Each of the vehicles 10 is set with assignment information, route information including overtaking points, and speed information, and drives according to the task. In this case, a passenger or a driver on board each vehicle 10 can check the task, driving route, and speed.

[0048] Next, the acquisition unit 205a acquires the vehicle 10 via the communication unit 201. 1 ~Vehicle 10 n The position information is acquired from each of the above (step S107).

[0049] After that, the determination unit 205g determines whether the vehicle 10 1 ~Vehicle 10 n Based on the position information of each of the vehicles 10, it is determined whether or not a traffic jam occurs on the predetermined travel route (step S108). 1 ~Vehicle 10 nBased on the position information of each of the vehicles 10 in a predetermined area, 1 ~Vehicle 10 n The determination unit 205g calculates the density of vehicles 10 that are present within a predetermined area on the predetermined travel route, and determines whether the density is equal to or greater than a threshold. If the density is equal to or greater than the threshold, the determination unit 205g determines that a traffic jam is occurring on the predetermined travel route. 1 ~Vehicle 10 n The actual speed is obtained from each of the vehicles 10. 1 ~Vehicle 10 n In this case, the determination unit 205g may determine whether or not a traffic jam occurs on a predetermined travel route based on the position information of the vehicle 10 within a predetermined area. 1 ~Vehicle 10 n The speed information set for each of the vehicles 10 in a given area is 1 ~Vehicle 10 n The actual speed of each of the vehicles 10 in a given area is compared with 1 ~Vehicle 10 n The actual speed of each vehicle is 1 ~Vehicle 10 n If the speed is slower than the speed information set in each of the above, it is determined that congestion has occurred on the predetermined travel route. If the determination unit 205g determines that congestion has occurred on the predetermined travel route (step S108: Yes), the management server 20 proceeds to step S109, which will be described later. On the other hand, if the determination unit 205g determines that congestion has not occurred on the predetermined travel route (step S108: No), the management server 20 proceeds to step S110, which will be described later.

[0050] In step S109, the drive control unit 205h instructs the target vehicle that is in a traffic jam on the predetermined travel route determined by the determination unit 205g to be congested to move to an overtaking point. 1 ~Vehicle 10 nThe speed information set in each of the above is compared with the actual speed, and a vehicle 10 whose difference between the speed information and the actual speed falls within a predetermined range is specified as a target vehicle. Then, the drive control unit 205h instructs the target vehicle to move to the overtaking point and stop temporarily for a predetermined time via the communication unit 201. In this case, the ECU 110 of the target vehicle moves to the overtaking point by controlling the drive unit 102 based on the instruction from the management server 20 and the driving route information including the overtaking point stored in the storage unit 109. At this time, the drive control unit 205h stops the target vehicle at the overtaking point until a predetermined time has elapsed or the distance between the target vehicle and the following vehicle becomes a predetermined distance after the following vehicle of the target vehicle has overtaken the target vehicle. Furthermore, the drive control unit 205h acquires the number of passengers of the target vehicle via the communication unit 201, and when the target vehicle is stopped at the overtaking point and the number of passengers of the target vehicle exceeds half of the capacity of the target vehicle, the drive control unit 205h opens the openable door of the target vehicle. This allows ventilation of the target vehicle. Note that, after the vehicle following the target vehicle has overtaken the target vehicle, the drive control unit 205h may decelerate the speed of the target vehicle until the distance between the following vehicle and the target vehicle becomes a predetermined distance.

[0051] If the task for each vehicle 10 is completed (step S110: Yes), the management server 20 ends this process. On the other hand, if the task for each vehicle 10 is not completed (step S110: No), the management server 20 returns to step S107.

[0052] According to the embodiment described above, the drive control unit 205h instructs the target vehicle that is in a traffic jam on a predetermined travel route, which is determined by the determination unit 205g to be in a traffic jam, to move to an overtaking point. 1 ~Vehicle 10 n Even if the vehicle is moving, 1 ~Vehicle 10 n can be operated.

[0053] According to one embodiment, the determination unit 205c determines whether the vehicle 10 1 ~Vehicle 10 n For each of the vehicles 10, when a traffic jam occurs on the travel route, travel route information is generated and set including an overtaking point for allowing the following vehicle to proceed ahead. Therefore, the operator who manages the management system 1 does not need to instruct the target vehicle on the overtaking point, and the vehicle 10 can proceed smoothly. 1 ~Vehicle 10 n can be operated.

[0054] According to one embodiment, since the overtaking point is a straight road having a predetermined road width, the following vehicle can overtake the target vehicle without any delay. 1 ~Vehicle 10 n can be operated.

[0055] According to one embodiment, the overtaking point is a place where the vehicle can depart from the travel route and make a temporary stop (for example, a bus stop), so the following vehicle can overtake the target vehicle without any delay. 1 ~Vehicle 10 n can be operated.

[0056] According to one embodiment, the drive control unit 205h temporarily stops the vehicle following the target vehicle at the overtaking point after the target vehicle has overtaken the target vehicle until a predetermined time has elapsed or until the distance between the target vehicle and the following vehicle becomes a predetermined distance. 1 ~Vehicle 10 n can be operated.

[0057] Furthermore, according to one embodiment, the drive control unit 205h acquires the number of occupants of the target vehicle via the communication unit 201, and when the target vehicle is stopped at an overtaking point and the number of occupants of the target vehicle exceeds half of the target vehicle's capacity, the openable and closable doors of the target vehicle are opened, thereby allowing ventilation of the target vehicle.

[0058] In one embodiment, the drive control unit 205h may decelerate the speed of the target vehicle after the vehicle following the target vehicle has passed the target vehicle until the distance between the following vehicle and the target vehicle becomes a predetermined distance. 1 ~Vehicle 10 n can be operated.

[0059] Furthermore, in the management system according to an embodiment, the word "unit" can be read as "circuit" etc. For example, a server control unit can be read as a server control circuit.

[0060] In addition, the program to be executed by the management system of one embodiment is provided as file data in an installable or executable format recorded on a computer-readable recording medium such as a CD-ROM, a flexible disk (FD), a CD-R, a Digital Versatile Disk (DVD), a USB medium, or a flash memory.

[0061] Furthermore, the program executed by the management system according to one embodiment may be configured to be stored on a computer connected to a network such as the Internet and provided by being downloaded via the network.

[0062] In the description of the flowcharts in this specification, the order of processing between steps is clearly indicated using expressions such as "first," "then," and "continue," but the order of processing required to implement this embodiment is not uniquely determined by these expressions. In other words, the order of processing in the flowcharts described in this specification can be changed as long as there is no contradiction.

[0063] Further advantages and modifications may readily occur to those skilled in the art.
