FIG. 1 is a block diagram showing an example of the configuration of a management device 10 according to one embodiment. The management device 10 constitutes a management system that manages the use of a loaned mobile object 30. The management device 10 is connected to a communication device 32 provided in the mobile object 30 via a communication network 20. An example of the communication network 20 is the Internet. The management device 10 is connected to a terminal device 42 carried by a driver 40 of the mobile object 30 via the communication network 20. The mobile object 30 is loaned to the driver 40.

The moving body 30 is, for example, a vehicle. In this embodiment, the moving body 30 is described as a vehicle. The moving body 30 may be another moving body such as a robot or an aircraft. The driver 40 is prohibited from lending the loaned moving body 30 to another person. Despite this, the driver 40 may lend the loaned moving body 30 to another person. The management device 10 can detect such inappropriate use of the moving body 30 by the driver 40.

The management device 10 may be configured by a server computer or the like, but is not limited to this. The management device 10 may be provided with a calculation unit 50, a memory unit 52, a communication unit 54, and an alarm unit 56. The management device 10 may also be provided with components other than these components, but a description of these will be omitted here. The calculation unit 50 may be configured by a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). In other words, the calculation unit 50 may be configured by a processing circuit.

The calculation unit 50 may include a control unit 70, an acquisition unit 72, a judgment unit 74, and a warning unit 76. The calculation unit 50 may also include components other than these components, but the description of these components will be omitted here. At least some of the control unit 70, acquisition unit 72, judgment unit 74, and warning unit 76 may be realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array).

In addition, at least some of the control unit 70, acquisition unit 72, determination unit 74, and warning unit 76 may be configured with electronic circuits including discrete devices.

The control unit 70 is responsible for the overall control of the management device 10. The control unit 70, the acquisition unit 72, the determination unit 74, and the warning unit 76 can be realized by the calculation unit 50 executing a program stored in the memory unit 52.

The memory unit 52 may include a volatile memory (not shown) and a non-volatile memory (not shown). An example of the volatile memory may be a RAM (Random Access Memory). The volatile memory is used as a working memory for the processor, and temporarily stores data and the like required for processing or calculations. An example of the non-volatile memory may be a ROM (Read Only Memory), flash memory, and the like. The non-volatile memory is used as a storage memory, and stores programs, tables, maps, and the like.

At least a part of the storage unit 52 may be provided in a processor, an integrated circuit, or the like as described above. The storage unit 52 may further include a hard disk drive (HDD), a solid state drive (SSD), or the like. An application program for causing a computer to execute the management method by the management device 10 is pre-installed in the storage unit 52.

The storage unit 52 may also include a mobile unit rental information storage unit 90 and a driving history information storage unit 92. The mobile unit rental information storage unit 90 stores mobile unit rental information. The driving history information storage unit 92 stores driving history information. Driver judgment information is generated using the driving history information. Details of the mobile unit rental information, driving history information, and driver judgment information will be described later. At least a portion of the storage unit 52 may be configured by a storage (not shown) that is provided separately from the management device 10.

As described above, the management device 10 may be provided with a communication unit 54. The communication unit 54 may include, for example, a communication module (not shown). The communication unit 54 may communicate with a communication device 32 mounted on the mobile object 30 via the communication network 20. The communication unit 54 may also communicate with a terminal device 42 carried by the driver 40 via the communication network 20.

As described above, the management device 10 may be provided with an alarm unit 56. The alarm unit 56 is provided with a display element (not shown). For example, a liquid crystal display element, an organic electroluminescence display element, etc. may be used as the display element.

As described above, the mobile body 30 may be equipped with a communication device 32. The communication device 32 generates driving history information based on information collected by various sensors provided in the mobile body 30. The sensors provided in the mobile body 30 include, for example, a positioning sensor, a speed sensor, an acceleration sensor, a throttle position sensor, and a brake sensor. The communication device 32 transmits the driving history information to the management device 10 via the communication network 20.

As described above, the calculation unit 50 of the management device 10 may be provided with an acquisition unit 72. The acquisition unit 72 acquires the driving history information transmitted from the communication device 32 to the management device 10 via the communication network 20 and the communication unit 54. The acquisition unit 72 stores the acquired driving history information in the driving history information storage unit 92 of the management device 10.

As described above, the calculation unit 50 of the management device 10 may be provided with a judgment unit 74. The judgment unit 74 reads out two pieces of driving history information obtained in a first period and a second period, which are different from each other, from the driving history information storage unit 92. The second period is a period after the first period. The judgment unit 74 uses the two pieces of driving history information to generate driver judgment information for the first period and driver judgment information for the second period. The judgment unit 74 judges the difference between the driver judgment information obtained in the first period and the driver judgment information obtained in the second period.

As described above, the calculation unit 50 of the management device 10 may be provided with a warning unit 76. The warning unit 76 issues a warning based on the difference determined by the determination unit 74. Specifically, the warning unit 76 supplies information for notifying the warning to the notification unit 56. The warning unit 76 may also supply information for outputting the warning to the terminal device 42 carried by the driver 40.

FIG. 2 is a diagram for explaining the period during which the driver 40 drives the mobile unit 30. The mobile unit 30 is loaned to the driver 40. For example, the first week is set as the period starting from the day the driver 40 drives the loaned mobile unit 30 for the first time. The period including the day the driver 40 drives the mobile unit 30 for the first time is called the trial period TA. The trial period TA is a period during which whether the driver 40 who has borrowed the mobile unit 30 is performing good driving is evaluated.

The driver's 40 driving of the mobile unit 30 is evaluated based on the driving history information acquired during the trial period TA. If the driver's 40 driving during the trial period TA is evaluated as good, the mobile unit 30 is officially loaned to the driver 40 from the second week after the trial period TA ends. From the second week onwards, driving history information is acquired for each weekly period. If the Nth week has passed up to the present time, the Nth week is the latest period TB. In other words, the latest period TB is the period that includes the day the driver 40 last drove the mobile unit 30.

Let us assume that at some point after the second week, individual IA, who is the driver 40 who rented the mobile unit 30, lends the mobile unit 30 to individual IB, who is a driver 40 different from individual IA. As described above, this constitutes an inappropriate use of the loaned mobile unit 30. In each period after the mobile unit 30 is loaned to individual IB, individual IB drives the mobile unit 30. That is, individual IA drives the mobile unit 30 as driver 40 during trial period TA, and individual IB drives the mobile unit 30 as driver 40 during the latest period TB.

In that case, a difference may occur between the driver judgment information obtained during the trial period TA and the driver judgment information obtained during the latest period TB. Therefore, based on this difference, inappropriate use of the loaned mobile unit 30 may be detected. Note that the trial period TA corresponds to the first period described above. The latest period TB corresponds to the second period described above.

FIG. 3 is a diagram illustrating an example of mobile unit rental information. The mobile unit rental information is stored in the mobile unit rental information storage unit 90. The mobile unit rental information includes a mobile unit ID for identifying the mobile unit 30, a driver ID for identifying the driver 40, and a terminal ID for identifying the terminal device 42.

The mobile unit ID and driver ID are input and stored by the person lending the mobile unit 30 when the mobile unit 30 is lent to the driver 40. The terminal ID is input and stored by the driver 40 operating the terminal device 42. In the example shown in FIG. 3, the driver ID of the driver 40 who has rented a mobile unit 30 with a mobile unit ID of M1 is D1. The terminal ID of the terminal device 42 held by the driver 40 with the driver ID of D1 is C1.

FIG. 4 is a diagram illustrating an example of driving history information. Driving history information is stored in the driving history information storage unit 92 for each moving body 30. The driving history information may include information indicating a time and information indicating the position of the moving body 30 at that time. The driving history information may include information indicating the speed of the moving body 30 and information indicating the acceleration of the moving body 30. The time and position information is collected by the positioning sensor described above. The position is represented by latitude and longitude. The speed information is collected by the speed sensor described above. The acceleration information is collected by the acceleration sensor described above.

The driving history information may further include information on the throttle opening degree when the driver 40 drives the mobile body 30, and information on the brake operation when the driver 40 drives the mobile body 30. The throttle opening degree information is collected by the throttle position sensor described above. The brake operation information is collected by the brake sensor described above. The driving history information generated based on the information collected by the various sensors described above is stored in the driving history information storage unit 92.

In the example shown in FIG. 4, the position of the moving body 30 with a moving body ID of M1 at time T1 is P1. The speed of the moving body 30 at time T1 is V1. The acceleration of the moving body 30 at time T1 is A1. The throttle opening of the moving body 30 at time T1 is QA1. The brake operation of the moving body 30 at time T1 is QB1. Driving history information is accumulated based on information collected by various sensors at various times. Using the driving history information accumulated in this manner, driver judgment information is generated by the judgment unit 74.

FIG. 5 is a diagram illustrating an example of the correspondence between driver determination information and driving history information. The driver determination information is used to determine the driver 40 who drives the mobile unit 30. The driver determination information includes, for example, storage location information indicating the location of the storage location where the mobile unit 30 is stored. After daily use by the driver 40, the mobile unit 30 may be stored unattended and powered off in a storage location, for example, on the driver's 40's home premises or near the driver's home. The storage location of the mobile unit 30 is where the mobile unit 30 may stay for the longest time during each period shown in FIG. 2. Therefore, as driving history information used for storage location information for a certain period, for example, information on the location where the mobile unit 30 stayed for the longest time during that period is used.

The driver determination information includes, for example, workplace location information indicating the location of the workplace to which the driver 40 drives the mobile unit 30 each day. During working hours when the driver 40 is working at the workplace, the mobile unit 30 may stay within the workplace premises or near the workplace. However, the working hours are shorter than the storage time during which the mobile unit 30 is stored in the storage location described above. Therefore, as driving history information used for the workplace location information for a certain period, for example, information on the location of the point where the mobile unit 30 stayed for the second longest time during that period, after the storage time, is used.

The driver determination information includes, for example, destination position information indicating the positions of destinations visited daily by the driver 40 while driving the mobile unit 30. When the driver 40 travels to a destination using the mobile unit 30, the driver spends time at the destination. Therefore, the mobile unit 30 stays at the destination for a certain length of time. Therefore, as driving history information used for destination position information for a certain period of time, for example, information on the positions of points where the mobile unit 30 stayed for a predetermined time threshold or more during that period of time is used. However, the positions of the storage place and workplace described above are not used for the destination position information. The distribution of destination positions obtained in this way may represent the living area of the driver 40.

The driver determination information includes, for example, information indicating the driving history when the driver 40 drove the mobile body 30, among the driving history information shown in FIG. 4. As described above, the driving history information is generated based on information collected by various sensors provided in the mobile body 30. The information collected by the various sensors specifically indicates the sensor values collected by the various sensors. The amount of change in the various sensor values when the driver 40 drives the mobile body 30 may suggest the driving characteristics of the driver 40. A specific example of a driving characteristic is, for example, sudden acceleration at a specific point. Therefore, information on the amount of change in the various sensor values of the mobile body 30 driven by the driver 40 is used as information indicating the driving history for a certain period of time.

FIG. 6A is a diagram illustrating a state in which a warning message 120 is displayed on the notification unit 56 of the management device 10. The warning unit 76 issues a warning to the notification unit 56 based on the difference determined by the determination unit 74. The warning issued by the warning unit 76 indicates that the management device 10 has determined that the mobile unit 30 has been rented to an individual IB, who is a driver 40 different from individual IA, who is a driver 40 during the trial period TA.

The notification unit 56 displays a warning message 120 on the screen based on the warning issued by the determination unit 74. The notification unit 56 may also play a warning sound based on the warning issued by the determination unit 74. The lender of the mobile unit 30 who visually recognizes the warning message 120 may take measures to stop the driver 40 from inappropriately using the mobile unit 30.

FIG. 6B is a diagram illustrating a state in which a warning message 120 is displayed on the terminal device 42. The terminal device 42 displays a warning message 120 similar to that shown in FIG. 6A on the screen based on the warning issued by the determination unit 74. The terminal device 42 may play a warning sound based on the warning issued by the determination unit 74. The driver 40 who sees the warning message 120 may be motivated to stop inappropriate use of the mobile object 30.

FIG. 7 is a flowchart showing an example of the operation of the management device 10. FIG. 7 illustrates a processing procedure for acquiring driving history information by the acquisition unit 72. This processing procedure is started when driving history information is transmitted from the communication device 32 mounted on the mobile object 30 to the management device 10.

When this processing procedure starts, in step S1, the acquisition unit 72 acquires driving history information from the communication device 32 via the communication network 20 and the communication unit 54. In step S2, the acquisition unit 72 stores the acquired driving history information in the driving history information storage unit 92. When the processing of step S2 is completed, this processing procedure ends.

FIG. 8 is a flowchart showing an example of the operation of the management device 10. FIG. 8 illustrates an example of the processing procedure of the driver judgment process performed by the management device 10. This processing procedure is started each time each period shown in FIG. 2 elapses. When this processing procedure is started, in step S11, the judgment unit 74 reads out the driving history information acquired in the first period and the driving history information acquired in the second period after the first period from the driving history information storage unit 92. The first period is, for example, the trial period TA shown in FIG. 2. The second period is, for example, the latest period TB shown in FIG. 2.

In step S12, the determination unit 74 generates information for driver determination in the first period using the driving history information acquired in the first period. The determination unit 74 also generates information for driver determination in the second period using the driving history information acquired in the second period.

In step S13, the determination unit 74 determines the difference between the driver determination information obtained in the first period and the driver determination information obtained in the second period. By determining the difference in the driver determination information, inappropriate use of the mobile body 30 loaned to the driver 40 can be detected. In step S14, the determination unit 74 determines whether or not a difference was determined in step S13. If the answer is YES in step S14, the process proceeds to step S15. If the answer is NO in step S14, the process ends.

In step S15, the warning unit 76 issues a warning to the notification unit 56 of the management device 10 and to the terminal device 42 carried by the driver 40. By issuing a warning, inappropriate use of the vehicle 30 loaned to the driver 40 can be stopped. When the processing of step S15 is completed, this processing procedure ends.
