[1. Overview of vehicle management system]
FIG. 1 is an explanatory diagram showing an overview of a vehicle management system 1 according to the present embodiment. The vehicle management system 1 provides a vehicle V and executes a vehicle provision service. The vehicle management system 1 includes a vehicle management device 100. Vehicle management system 1 may include an evaluator terminal 220 that communicates with vehicle management device 100 via communication network 500. Further, the vehicle management system 1 may include a user terminal 210. The vehicle management system 1 corresponds to an example of an information management system. Further, the vehicle management device 100 can be called an information management device.

The vehicle provision service provided by the vehicle management system 1 is, for example, a vehicle rental service in which a vehicle V is rented out. Vehicle rental services include car sharing, rental cars, and car leases. In this embodiment, an example will be described in which the vehicle management system 1 implements a car sharing service. User U is, for example, a person registered in advance in vehicle management device 100 as a member of a car sharing service, and is a user of the service. Further, in this embodiment, an example will be described in which the vehicle V is a four-wheeled vehicle.

The vehicle management device 100 is a device operated by a company that provides car sharing services, and is, for example, a server device.
The vehicle management device 100 communicates with a user terminal 210, which is a terminal device used by the user U, and executes various data processing for lending the vehicle V to the user U. Vehicle management device 100 accepts an application for lending vehicle V in response to user U's request. The vehicle V has means (not shown) that allows the user U to unlock and lock the vehicle V under the control of the vehicle management device 100. For example, the doors of the vehicle V can be unlocked and locked by wireless communication between an IC card or user terminal 210 owned by the user U and an in-vehicle device (not shown) installed in the vehicle V. It is. Furthermore, the on-vehicle device mounted on the vehicle V can start and stop the system of the vehicle V, start and stop the engine of the vehicle V, and release and operate the parking brake of the vehicle V according to the operations of the user U. . This allows the user U to use the vehicle V and return the vehicle V without an employee of the business providing the car sharing service being present at the rental.

Vehicle management device 100 communicates with evaluator terminal 220, which is a terminal device used by evaluator Vo who evaluates the state of vehicle V. The vehicle management device 100 acquires the results of the evaluation by the evaluator Vo from the evaluator terminal 220. The evaluator Vo evaluates the state of the vehicle V in response to a request from a company that operates the vehicle management system 1. For example, evaluator Vo evaluates the exterior and interior of vehicle V after user U returns vehicle V. Details of the evaluation by evaluator Vo will be described later. It is preferable that the evaluator Vo is not a person related to the service provider that operates the vehicle management system 1 and the vehicle management device 100, nor is the user U who uses the service provided by the vehicle management system 1. In this case, it is ensured that the evaluator Vo evaluates the vehicle V from a neutral standpoint.

The user terminal 210 and the evaluator terminal 220 are mobile devices or portable computers called handheld computers. For example, a smartphone or a tablet computer. The evaluator terminal 220 corresponds to an example of an external device for the vehicle management device 100.

The user terminal 210 of this embodiment has a touch panel 211, and the evaluator terminal 220 has a touch panel 221. The touch panels 211 and 221 are devices in which a display panel such as a liquid crystal display panel or an organic EL panel and a touch sensor that detects a touch operation are superimposed. Touch panels 211 and 221 function as a display device and an input device.

The user terminal 210 displays an input screen on the touch panel 211 and receives input from the user U in a process such as applying for rental of the vehicle V. A screen displayed on touch panel 211 functions as a user interface.
The evaluator terminal 220 displays an input screen on the touch panel 221 and receives input from the evaluator Vo in a process in which the evaluator Vo inputs the evaluation results of the vehicle V. The screen displayed on the touch panel 221 functions as a user interface.
The above configuration is an example; for example, the user U may use a desktop computer as the user terminal 210.

Evaluator Vo can use odor sensor 230 as a device for evaluating the odor in the cabin of vehicle V. The odor sensor 230 detects organic compounds contained in the air and outputs a detected value indicating at least one of the strength of the odor, the quality of the odor, and the quality of the air. The odor sensor 230 is connected to the evaluator terminal 220 by, for example, wireless communication such as Bluetooth (registered trademark) or a communication cable. The evaluator terminal 220 communicates with the odor sensor 230 according to the operation of the evaluator Vo, and acquires the detection value of the odor sensor 230. Evaluator Vo may evaluate the odor using his/her sense of smell without using odor sensor 230.

Vehicle management device 100 is connected to communication network 500 and performs data communication with user terminal 210 and evaluator terminal 220 via communication network 500. The communication network 500 may be any data communication network, such as a wide area communication network including a public line network, a LAN (Local Area Network), and the like. The management device 200 is, for example, a server device, and may be a cloud-type server.

The vehicle management device 100 has a vehicle information storage section 110. The vehicle information storage unit 110 stores information regarding the vehicle V provided by the vehicle management system 1 and various accompanying information. Although details will be described later, the vehicle information storage unit 110 stores information including an evaluation result that is the result of the evaluation of the vehicle V by the evaluator Vo. Vehicle information storage section 110 corresponds to an example of an evaluation storage section.
Vehicle management device 100 transmits information stored in vehicle information storage unit 110 to user terminal 210 when user U requests rental of vehicle V. For example, user U can know the evaluation result of vehicle V before renting vehicle V.

FIG. 2 is a schematic diagram showing an example of information stored in the vehicle information storage unit 110.
Vehicle information storage section 110 stores vehicle information 120, vehicle evaluation information 130, rental history information 140, and evaluator information 150.
The vehicle information 120 includes a vehicle ID 121 and a registration number 122 of the vehicle V provided by the vehicle management system 1. The vehicle information storage unit 110 stores one piece of vehicle information 120 for one vehicle V provided by the vehicle management system 1. Vehicle ID 121 is unique identification information given to vehicle V. The registration number 122 is a number given to the vehicle V by an administrative system, and is the number of a so-called license plate or vehicle registration plate. The registration number 122 may be omitted, or the registration number 122 may be used as the vehicle ID 121.

Vehicle evaluation information 130 includes vehicle ID 131, vehicle evaluation 132, evaluation date and time 133, and evaluator ID 134. The vehicle information storage unit 110 stores one piece of vehicle evaluation information 130 for one vehicle V provided by the vehicle management system 1. Vehicle ID 131 is the same information as vehicle ID 121. Vehicle evaluation 132 is the result of evaluation of vehicle V by evaluator Vo. The evaluation date and time 133 is information indicating the date and time when the evaluator Vo evaluated the vehicle V. The evaluator ID 134 is identification information that can identify the evaluator Vo who performed the evaluation. The evaluation date and time 133 may be omitted.

In the vehicle management system 1, an evaluator Vo evaluates one vehicle V periodically or at a specific timing. Every time the evaluator Vo evaluates the vehicle V, the vehicle evaluation information 130 associated with the evaluated vehicle V is updated. When the vehicle evaluation information 130 is updated, the vehicle management system 1 stores the vehicle evaluation information 130 before the update in the vehicle information storage unit 110 for a certain period of time. The vehicle management system 1 stores the vehicle evaluation information 130 before the update and the vehicle evaluation information 130 after the update in a distinguishable form in the vehicle information storage unit 110.

FIG. 3 is a schematic diagram showing an example of vehicle evaluation information 130, and shows an example of information included in vehicle evaluation 132 in detail.
In the example shown in FIG. 3, the vehicle evaluation 132 includes an exterior rank 132a, an interior rank 132b, an exterior image 132c, an interior image 132d, an odor evaluation value 132e, and additional information 132f. The exterior rank 132a is an evaluation value obtained by evaluating the state of the exterior of the vehicle V by the evaluator Vo. The exterior rank 132a and the interior rank 132b are determined and evaluated by evaluator Vo by visual observation, touch, and the like. The evaluation of the exterior rank 132a and the interior rank 132b is performed, for example, by the evaluator Vo determining whether preset evaluation items are applicable or not applicable. The evaluation item is, for example, a combination of parts and damage on the vehicle V. In this case, the evaluation result of the exterior rank 132a is a numerical value that is a summation of the evaluations of evaluation items regarding the exterior of the vehicle V, and the evaluation result of the interior rank 132b is a numerical value that is a summation of the evaluations of evaluation items regarding the interior of the vehicle V. Moreover, the evaluation of the exterior rank 132a and the interior rank 132b may be, for example, values subjectively ranked by the evaluator Vo. These are just examples, and the vehicle evaluation 132 does not need to include all of the exterior rank 132a, interior rank 132b, exterior image 132c, interior image 132d, odor evaluation value 132e, and additional information 132f.

The vehicle exterior image 132c is a photographed image of the exterior of the vehicle V taken with a digital camera, and the vehicle interior image 132d is a photographed image of the interior of the vehicle V taken with a digital camera. For example, the evaluator Vo takes a picture with a camera (not shown) included in the evaluator terminal 220, and uploads the captured image from the evaluator terminal 220 to the vehicle management device 100. The vehicle management device 100 stores the uploaded images in the vehicle information storage unit 110 as an outside-vehicle image 132c and an inside-vehicle image 132d. The vehicle evaluation information 130 may include information indicating the shooting date and time of the vehicle exterior image 132c and the vehicle interior image 132d.

The odor evaluation value 132e is an evaluation result of the strength and quality of the odor in the cabin of the vehicle V. The odor evaluation value 132e may be the result of evaluation by the evaluator Vo using his or her sense of smell. Further, the odor evaluation value 132e may be a measurement result measured by the evaluator Vo using the odor sensor 230.

The additional information 132f is information input by the evaluator Vo regarding the state of the vehicle V. For example, when evaluator Vo records information regarding the condition of vehicle V that does not correspond to exterior rank 132a, interior rank 132b, and odor evaluation value 132e, this information is stored in vehicle information storage unit 110 as additional information 132f. Ru.

Returning to FIG. 2, the rental history information 140 includes a vehicle ID 141, a rental date and time 142, a return date and time 143, a user ID 144, and a user evaluation 145. Vehicle information 120 is generated each time one vehicle V provided by vehicle management system 1 is lent to user U once. That is, the vehicle information storage unit 110 stores one piece of lending history information 140 in response to one lending of one vehicle V. Vehicle ID 141 is the same information as vehicle ID 121. The rental date and time 142 indicates the date and time when the vehicle V was rented to the user U. The return date and time 143 indicates the date and time when the vehicle V was returned by the user U. The user ID 144 is identification information that can identify the user U who borrowed the vehicle V. User evaluation 145 is the evaluation result of user U evaluating vehicle V. This is just an example, and the rental history information 140 only needs to include at least the vehicle ID 141 and the user evaluation 145.

The evaluator information 150 includes an evaluator ID 151 and evaluator characteristics 152. The evaluator ID 151 is identification information of the evaluator Vo, and is the same information as the evaluator ID 134. The vehicle information storage unit 110 stores one piece of evaluator information 150 for one evaluator Vo who evaluates the vehicle V provided by the vehicle management system 1. The evaluator characteristics 152 are information indicating the characteristics of the evaluator Vo. In this embodiment, the evaluator characteristics 152 include an evaluation value for evaluator Vo and an evaluation tendency of evaluator Vo. The evaluation value is an index indicating the validity of the evaluation performed by the evaluator Vo, and is, for example, a value that quantifies the validity of the evaluation by the evaluator Vo. This numerical value corresponds to an index indicating the quality of the evaluation results performed by the evaluator. The evaluation tendency indicates the evaluation tendency of the evaluator Vo. For example, it can be set to either "severe" indicating that the evaluator tends to evaluate vehicles harshly, or "severe" indicating that the evaluator tends to lightly evaluate vehicle stains, etc.

[3. Operation of vehicle management system]
FIG. 5 is a sequence diagram showing the operations of the vehicle management device 100 and the evaluator terminal 220. FIG. 5 shows an operation in which the evaluator Vo evaluates the vehicle V and uploads the evaluation results to the vehicle management device 100. Steps SA11 to SA16 are operations of the evaluator terminal 220. Steps SB11 to SB16 are operations of the vehicle management device 100, and are executed by the evaluation acquisition unit 11.

Evaluator terminal 220 transmits an evaluation start request to vehicle information storage unit 110 in accordance with the operation of evaluator Vo (step SA11). The evaluation start request is data indicating that the evaluation of the vehicle V is to be started, and includes information specifying the vehicle V to be evaluated and information specifying the evaluator Vo. The information that identifies the vehicle V is, for example, a vehicle ID or a registration number. The information identifying the evaluator Vo is, for example, the evaluator ID.

Vehicle management device 100 receives the evaluation start request (step SB11). Vehicle management device 100 collates the information included in the evaluation start request with vehicle information 120 and evaluator information 150. Vehicle management device 100 identifies evaluator Vo based on evaluator information 150 (step SB12), and identifies vehicle V to be evaluated based on vehicle information 120 (step SB13).

Vehicle management device 100 transmits an evaluation input user interface (hereinafter abbreviated as UI) for evaluator Vo to input evaluation results to evaluator terminal 220 (step SB14). Evaluator terminal 220 receives the evaluation input UI from vehicle management device 100 and displays it on touch panel 221 (step SA12).

FIG. 6 is a diagram showing an example of a screen displayed by the evaluator terminal 220. The evaluation input screen 301 shown in FIG. 6 is an example of a user interface for evaluation input.
On the evaluation input screen 301, a vehicle information display section 302 and an evaluator information display section 303 are arranged. The vehicle information display section 302 displays the vehicle ID and registration number of the vehicle V to be evaluated. The vehicle information display section 302 displays the evaluator ID of the evaluator Vo who performs the evaluation. The information displayed on the vehicle information display section 302 and the evaluator information display section 303 is information acquired by the vehicle management device 100 from the vehicle information 120 and evaluator information 150 in the vehicle information storage section 110. The evaluator Vo performs the evaluation after checking the information displayed on the vehicle information display section 302 and the evaluator information display section 303.

The evaluation input screen 301 includes an evaluation input section 310. The evaluation input section 310 includes input areas 311, 312, 316, and 317 for the evaluator Vo to input evaluation results. The evaluator Vo inputs the evaluation result of the appearance rank of the vehicle V into the input area 311. The evaluation result input into the input area 311 is stored as an exterior rank 132a. The evaluator Vo inputs the evaluation result of the interior rank of the vehicle V into the input area 312. The evaluation result input into the input area 312 is stored as an interior decoration rank 132b.

The evaluator Vo inputs additional information regarding the evaluation of the vehicle V into the input area 317. Information input into the input area 317 is stored as additional information 132f.

The evaluator Vo inputs the evaluation result of the odor inside the vehicle V into the input area 316. The evaluation input screen 301 includes an input area 316 and a button 315. The button 315 is a button for connecting the odor sensor 230 to the evaluator terminal 220 and instructing the odor sensor 230 to obtain a measurement value. When the button 315 is operated, the evaluator terminal 220 communicates with the odor sensor 230 and acquires the detected value of the odor sensor 230. When the button 315 is operated by the evaluator Vo, the information input into the input area 316 is canceled.

The evaluation input screen 301 has buttons 313 and 314. Button 313 is a button for instructing selection of a captured image of the exterior of vehicle V. Button 314 is a button for instructing selection of a photographed image of the inside of vehicle V.
When the evaluator Vo operates the button 313 or the button 314, the evaluator terminal 220 performs an operation of selecting an image to be transmitted to the vehicle management device 100 from the images taken by the camera included in the evaluator terminal 220. The evaluator terminal 220 transmits data of the image selected by the evaluator Vo to the vehicle management device 100.

In this way, the evaluator Vo uses the user interface displayed on the touch panel 221 to input the evaluation results for the vehicle V, and also sends the captured image data and the detection value of the odor sensor 230 to the vehicle management device 100. can be sent to.

Returning to FIG. 5, evaluator Vo inputs the evaluation result using the evaluation input UI (step SA13). Here, the evaluator terminal 220 determines whether connection with the odor sensor 230 has been instructed by operating the button 315 (step SA14). If button 315 is operated (step SA14; YES), evaluator terminal 220 acquires a detected value from odor sensor 230 (step SA15), and proceeds to step SA16. If button 315 is not operated (step SA14; NO), evaluator terminal 220 moves to step SA16.

The evaluator terminal 220 transmits the evaluation results input by the evaluator Vo using the evaluation input UI and data such as photographed image data and the detected value of the odor sensor 230 to the vehicle management device 100 (step SA16). . In step SA16, the evaluator terminal 220 manages the evaluation results input into the input areas 311, 312, 316, and 317 in FIG. The information is transmitted to the device 100. Further, when the button 315 is operated, the evaluator terminal 220 transmits the detection value acquired from the odor sensor 230 according to the operation of the button 315 to the vehicle management device 100 in step SA16.

Vehicle management device 100 receives the evaluation results and data transmitted from evaluator terminal 220 (step SB15). Vehicle management device 100 updates vehicle evaluation information 130 using the evaluation results and data received in step SB15 (step SB16).

In step SB16, vehicle management device 100 may update vehicle evaluation information 130 after correcting the evaluation result received in step SB15 based on the evaluation tendency included in evaluator characteristics 152. For example, if the evaluation tendency of the evaluator characteristic 152 of the evaluator Vo is "severe", there is a possibility that the evaluation result received in step SB15 is a more severe evaluation than the actual state of the vehicle V. In this case, the vehicle management device 100 updates the vehicle evaluation information 130 by correcting the evaluation result received in step SB15 so that it becomes a good evaluation result. For example, the vehicle management device 100 corrects the exterior rank 132a and the interior rank 132b by predetermined steps toward a good evaluation. Further, when the odor evaluation value 132e is the value input by the evaluator Vo, the odor evaluation value 132e is corrected by a predetermined value in the direction of a good evaluation. Here, if the odor evaluation value 132e is a detection value acquired from the odor sensor 230, the vehicle management device 100 does not correct the odor evaluation value 132e. Similarly, for example, if the evaluation tendency of the evaluator characteristic 152 of evaluator Vo is "poor", the vehicle management device 100 corrects the evaluation result received in step SB15 so that it becomes a bad evaluation result. Vehicle evaluation information 130 is updated. By this correction, it is possible to correct the tendency of the evaluations by the evaluators Vo, and it is possible to suppress the dispersion in the evaluations for each evaluator Vo.

FIG. 7 is a sequence diagram showing operations of the vehicle management device 100 and the user terminal 210. FIG. 7 shows a series of operations when the vehicle V is lent to the user U. Steps SC11 to SC21 are operations of the user terminal 210. Steps SB31 to SB40 are operations of the vehicle management device 100 and are executed by the rental processing unit 12.

The user terminal 210 transmits an application start request requesting a rental application to the vehicle management device 100 in accordance with the operation of the user U (step SC11). Vehicle management device 100 receives the application start request (step SB31). Vehicle management device 100 transmits vehicle evaluation information 130 regarding vehicles V that can be lent to user U to user terminal 210 (step SB32). The operation of vehicle management device 100 transmitting vehicle evaluation information 130 to user terminal 210 corresponds to outputting vehicle evaluation 132. The lending processing unit 12 that performs this operation corresponds to an example of an output unit.

In step SB32, the vehicle management device 100 uses the vehicle management system 1 to search for a vehicle V that can be lent to the user U, acquires the vehicle evaluation information 130 of the corresponding vehicle V from the vehicle information storage unit 110, and stores it in the user terminal 210. Send to. Here, the user terminal 210 may transmit the location information of the user U in step SC11, and the vehicle management device 100 may search for a vehicle V that can be rented near the user U based on the location information of the user U. Further, the vehicle management device 100 may transmit information regarding the rental fee of the vehicle V together with the vehicle evaluation information 130 in step SB32.

User terminal 210 receives vehicle evaluation information 130 transmitted by vehicle management device 100, and displays it on touch panel 211 (step SC12). When the information received from the vehicle management device 100 includes the vehicle evaluation information 130 of the plurality of vehicles V, the user terminal 210 displays a list of information regarding the plurality of vehicles V.
The user terminal 210 transmits a rental request for renting the vehicle V to the vehicle management device 100 in accordance with the operation of the user U (step SC13). The rental request transmitted by the user terminal 210 in step SC13 may include information specifying the vehicle V for which rental is requested.

Vehicle management device 100 receives a lending request from user terminal 210 (step SB33). Vehicle management device 100 generates rental history information 140 based on the rental request (step SB34). Vehicle management device 100 generates unlocking information for user U to unlock the door of vehicle V (step SB34), and transmits the unlocking information to user terminal 210 (step SB35). The user terminal 210 receives the unlocking information from the vehicle management device 100 (step SC14), and the user U uses the unlocking information to unlock the door of the vehicle V and gets into the vehicle V (step SC14). ).

For example, in a configuration in which the user terminal 210 and an on-vehicle device (not shown) mounted on the vehicle V perform wireless communication to unlock the vehicle V, the unlocking information may be electronic information sent by the user terminal 210 to the on-vehicle device. This is key data. The vehicle management device 100 may communicate with an on-vehicle device of the vehicle V to unlock the doors of the vehicle V by remote control. In this case, the vehicle management device 100 notifies the user terminal 210 that the door of the vehicle V has been unlocked. The method by which the user U unlocks the door of the vehicle V and puts the vehicle V into a drivable state is not limited to the above, and various known methods can be employed.

When returning the vehicle V, the user U operates the user terminal 210 after parking the vehicle V at the designated parking place Pa. The user terminal 210 transmits a return procedure request requesting execution of the return procedure to the vehicle management device 100 in accordance with the operation of the user U (step SC16). Vehicle management device 100 receives the return procedure request (step SB36), and transmits a user evaluation input UI for user U to input user evaluation to user terminal 210 (step SB37).

The user evaluation input UI is a user interface through which the user U inputs the evaluation result of the vehicle V. The user evaluation may be, for example, one value by which the user U evaluates the overall state of the vehicle V. Further, the user evaluation may be the degree of satisfaction of the user U with respect to the service of renting out the vehicle V. Further, the user evaluation may be the evaluation result of the user U evaluating the vehicle V for each of a plurality of items including the exterior, interior, and odor of the vehicle V, similar to the evaluation by the evaluator Vo.

The user terminal 210 receives the user evaluation input UI from the vehicle management device 100, and displays it on the touch panel 211 (step SC17). The user U inputs a user evaluation using the user evaluation input UI displayed on the touch panel 211 (step SC18). User terminal 210 transmits the user evaluation input by user U to vehicle management device 100 (step SC19).

Vehicle management device 100 receives the user evaluation from user terminal 210 (Step SB38), and updates rental history information 140 generated in Step SB34 based on the received user evaluation (Step SB39). Vehicle management device 100 transmits locking information for user U to lock vehicle V to user terminal 210 (step SB40).
The user terminal 210 receives the locking information from the vehicle management device 100 (step SC20), and the user U gets off the vehicle V and locks the door of the vehicle V using the locking information (step SC21).

For example, in a configuration in which the user terminal 210 and an on-vehicle device (not shown) mounted on the vehicle V perform wireless communication to lock the vehicle V, the locking information may be the electronic key information that the user terminal 210 sends to the on-vehicle device. It is data. Similar to the configuration described regarding the unlocking information, the vehicle management device 100 may communicate with the on-vehicle device of the vehicle V and lock the door of the vehicle V by remote control. The method by which the user U locks the door of the vehicle V is not limited to the above, and various known methods may be employed.

FIG. 8 is a flowchart showing the operation of the vehicle management device 100. FIG. 8 shows an operation in which the vehicle management device 100 corrects the evaluation by the evaluator Vo based on the user evaluation acquired from the user terminal 210. The operation in FIG. 8 is executed by the correction unit 13.

Vehicle management device 100 identifies vehicle V to be processed (step SB51). For example, the vehicle management device 100 may execute the process shown in FIG. 8 on the returned vehicle V every time the rental history information 140 is updated by the operation shown in FIG. In this case, the vehicle management device 100 selects the vehicle V whose rental history information 140 has been updated in step SB51. Further, the vehicle management device 100 may perform the process shown in FIG. 8 on all vehicles V periodically, for example. In this case, the vehicle management device 100 sequentially selects all the vehicles V handled by the vehicle management system 1 in step SB51, and executes the process of FIG. 8.

The vehicle management device 100 extracts the rental history information 140 related to the vehicle V identified in step SB51 from the rental history information 140 stored in the vehicle information storage unit 110, and obtains the user evaluation 145 (step SB52). ). In step SB52, it is preferable that the user evaluation 145 that was previously subjected to the process of FIG. 8 is removed.

Vehicle management device 100 acquires vehicle evaluation information 130 presented to user U when renting vehicle V from vehicle information storage unit 110 (step SB53). At step SB53, vehicle management device 100 acquires vehicle evaluation information 130 transmitted to user terminal 210 at step SB32 (FIG. 7) based on rental history information 140 corresponding to user evaluation 145 acquired at step SB52. This vehicle evaluation information 130 is information referenced by the user U when the user U inputs the user evaluation.

Vehicle management device 100 acquires evaluator ID 134 from vehicle evaluation information 130 acquired in step SB53, and identifies it as the evaluator ID to be processed (step SB54).

The vehicle management device 100 compares the user evaluation 145 acquired in step SB52 with the vehicle evaluation 132 included in the vehicle evaluation information 130 acquired in step SB53, and calculates the difference in evaluation (step SB55).

In step SB55, the vehicle management device 100 calculates the degree of deviation between the evaluation result of the vehicle V input by the evaluator Vo and the evaluation of the vehicle V perceived by the user U as a numerical value.
For example, when the user evaluation 145 is an evaluation value for the state of the vehicle V, the vehicle management device 100 converts the vehicle evaluation 132 into a numerical value that can be compared with the user evaluation 145 in step SB55, and the converted numerical value and the user evaluation 145 is calculated.
When the user evaluation 145 is an index indicating the degree of satisfaction of the user U, the vehicle management device 100 digitizes the degree of satisfaction of the user U and uses the obtained numerical value as a value indicating the difference in evaluation.

Vehicle management device 100 determines whether the difference in evaluation is greater than or equal to the first threshold (step SB56). If the difference in evaluation is greater than or equal to the first threshold (step SB56; YES), the vehicle management device 100 performs a process of updating the evaluator characteristic 152 of the evaluator Vo identified in step SB54 by lowering it by one rank (step SB57). ). Specifically, the vehicle management device 100 acquires the evaluator information 150 including the evaluator ID specified in step SB54, and updates the evaluator characteristics 152 included in this evaluator information 150 to a value lowered by one rank. .
That is, when the degree of deviation between the evaluation result of the vehicle V input by the evaluator Vo and the evaluation of the vehicle V perceived by the user U is large, the evaluation for the evaluator Vo is lowered. The first threshold value is set in advance together with a second threshold value and a reference value, which will be described later, and is stored in the storage unit 20 as reference value data 22.

Vehicle management device 100 determines whether or not updated evaluator characteristics 152 are equal to or less than a reference value (step SB58). If the evaluator characteristics 152 are below the reference value (step SB58; YES), the vehicle management device 100 includes the evaluator ID specified in step SB54 from the vehicle evaluation information 130 stored in the vehicle information storage unit 110. Vehicle evaluation information 130 is selected (step SB59). In step SB59, the vehicle management device 100 may search for the corresponding vehicle evaluation information 130 from all the vehicle evaluation information 130 stored in the vehicle information storage section 110. Further, in step SB59, the vehicle management device 100 may select the corresponding vehicle evaluation information 130 from among the vehicle evaluation information 130 updated within a predetermined period.

Vehicle management device 100 determines whether or not old vehicle evaluation 132 is stored in vehicle information storage unit 110 for selected vehicle evaluation information 130 (step SB60). As described above, when updating the vehicle evaluation information 130 in the process of FIG. 5, the vehicle management device 100 stores the vehicle evaluation information 130 before the update in the vehicle information storage unit 110 for a certain period of time. At step SB60, vehicle management device 100 determines whether vehicle evaluation information 130 before update is stored.

If the old vehicle evaluation 132 is stored in the vehicle information storage unit 110 (step SB60; YES), the vehicle management device 100 overwrites the vehicle evaluation information 130 selected in step SB59 based on the old vehicle evaluation 132 (step SB61). If the old vehicle evaluation 132 is not stored in the vehicle information storage unit 110 (step SB60; NO), the vehicle management device 100 deletes the vehicle evaluation 132 from the vehicle evaluation information 130 selected in step SB59 (step SB62). After performing the process of step SB61 or step SB62 for all the vehicle evaluation information 130 selected in step SB59, the vehicle management device 100 ends this process. Through the processing in steps SB61 and SB62, the vehicle evaluation 132 evaluated by the evaluator Vo whose evaluator characteristic 152 is equal to or less than the reference value is not output to the user U.

Furthermore, if the evaluator characteristics 152 updated in step SB57 is not less than the reference value (step SB58; NO), the vehicle management device 100 ends this process.

Furthermore, if the difference in the evaluations obtained in step SB55 is not equal to or greater than the first threshold (step SB56; NO), the vehicle management device 100 determines whether the difference in the evaluations is equal to or less than the second threshold (step SB63). . If the difference in evaluation is less than or equal to the second threshold (step SB63; YES), the vehicle management device 100 updates the evaluator characteristic 152 of the evaluator Vo identified in step SB54 by raising it by one rank (step SB64). In step SB54, vehicle management device 100 acquires evaluator information 150 including the evaluator ID identified in step SB54, and updates evaluator characteristics 152 included in this evaluator information 150 to a value that is one rank higher. . That is, when the degree of deviation between the evaluation result of the vehicle V input by the evaluator Vo and the evaluation of the vehicle V perceived by the user U is small, the evaluation for the evaluator Vo increases.
After processing step SB64, vehicle management device 100 ends this processing.

Further, if it is determined in step SB63 that the difference in evaluation is not equal to or less than the second threshold (step SB63; NO), the vehicle management device 100 updates the evaluation tendency of the evaluator characteristics 152 based on the tendency of the difference in evaluation. (Step SB65). In step SB65, vehicle management device 100 determines the direction of the difference in the evaluations obtained in step SB55. If evaluator Vo's evaluation is worse, the evaluation tendency of evaluator characteristics 152 is set to "severe", and if evaluator Vo's evaluation is better, it is set to "lenient". and updates the evaluator characteristics 152. Here, the vehicle management device 100 may aggregate the direction of the difference in evaluation for multiple evaluations performed by the evaluator Vo, and may change the evaluator characteristics 152.

Although the execution order of the processes shown in FIGS. 5, 7, and 8 can be changed arbitrarily, for example, after the evaluator Vo evaluates the vehicle V in the process in FIG. 5, the process in FIG. Preferably, it is lent to user U, and then the process of FIG. 8 is executed. In this case, the vehicle evaluation 132 by the evaluator Vo before the first user U borrows the vehicle V and before the second user U uses the vehicle The user evaluation 145 at the time is compared with the user evaluation 145 in the process shown in FIG. In other words, after the vehicle evaluation 132 of the vehicle V is generated based on the evaluation by the evaluator Vo, the user evaluation 145 by the user U to whom the vehicle V was first lent is compared with the vehicle evaluation 132, and the vehicle evaluation 132 is The characteristics of are determined. In this case, since there is almost no change in the state of the vehicle V from the generation of the vehicle evaluation 132 until the generation of the user evaluation 145, it is possible to more accurately determine and evaluate the characteristics of the evaluator Vo. becomes.
