[Description of vehicle information management method]
A vehicle information management method executed by the vehicle information management system S according to this embodiment will be described in detail below. FIG. 3 is a schematic diagram of a vehicle information management method executed by the vehicle information management system S according to this embodiment. In the example of FIG. 3, three or more information processing apparatuses 1 include a first information processing apparatus 1A, a second information processing apparatus 1B and a third information processing apparatus 1C.

The operation schedule storage unit 123 of the information processing device 1 stores the information of the vehicle 2 and the operation schedule of the vehicle 2, and is updated appropriately according to changes in the operation schedule. The information of the vehicle 2 is, for example, information in which identification information of the vehicle 2 (automobile registration number, etc.) and driver information of the vehicle 2 (user ID, name, telephone number, etc.) are associated with each other. The operation schedule of the vehicle 2 includes, for example, the operation route of the vehicle 2, the positions of the transportation source and transportation destination of the luggage loaded on the vehicle 2, and the like.

While the vehicle 2 is transporting a package, in the information processing device 1 associated with the vehicle 2 , the information acquisition unit 111 acquires an evaluation value indicating the quality of transportation of the package by the driver of the vehicle 2 . The evaluation value is a value that indicates at least one of information about time and information about vehicle speed. The information acquisition unit 111 may acquire a plurality of different evaluation values. The travel history (vehicle speed, acceleration/deceleration, travel position, etc.) of the vehicle 2 used to calculate the evaluation value is collected by a computer (ECU: Engine Control Unit, etc.) mounted on the vehicle 2, and is associated with the vehicle 2. It is sent to the processing device 1 . The computer of the vehicle 2 collects various information of the vehicle 2 by, for example, CAN (Controller Area Network) communication.

FIG. 4 is a schematic diagram for explaining evaluation values acquired by the information acquisition unit 111. As shown in FIG. The information about the time indicated by the evaluation value includes, for example, the difference between the planned time and the actual time for transporting the package from the transportation source to the transportation destination, and the continuous running time of the vehicle 2 .

The scheduled time is preset in the information processing device 1 . The driver uses the operation unit 14 of the information processing device 1 to perform a predetermined operation (for example, pressing a button or inputting time) when the package is collected from the transportation source and when the package is delivered to the transportation destination. conduct.

The information acquisition unit 111 calculates the time from the time when the package is collected from the transportation source to the time when the package is delivered to the transportation destination as the actual time. Then, the information acquisition unit 111 acquires the difference between the planned time and the actual time by subtracting the actual time from the scheduled time. The information acquisition unit 111 also acquires the continuous travel time during transportation of the package based on the travel history recorded by the computer mounted on the vehicle 2 .

The information about the vehicle speed indicated by the evaluation value includes, for example, maximum acceleration/deceleration, variations in acceleration/deceleration, and the number of overspeeding. The information acquisition unit 111 acquires the maximum acceleration/deceleration during transportation of the cargo based on the travel history recorded by the computer mounted on the vehicle 2, and also detects variations in acceleration/deceleration during transportation of the cargo (for example, acceleration/deceleration). variance or standard deviation).

Furthermore, based on the travel history recorded by the computer mounted on the vehicle 2, the information acquisition unit 111 calculates the number of overspeeding times, which is the number of times the vehicle speed exceeds the speed limit while the cargo is being transported. The speed limit may be a uniform speed (for example, 80 km/h) or a legal speed set for each travel position.

The information acquisition unit 111 is not limited to the information shown here, and may acquire other information indicating the quality of transportation of the package by the driver as the evaluation value.

Returning to FIG. 3, in the first information processing device 1A associated with the vehicle 2 when the vehicle 2 completes transportation of the package, the reliability calculation unit 112 calculates the Based on the evaluation value described above and the reference value stored in advance in the reference value storage unit 122, a reliability indicating the reliability of the transportation of the package by the driver of the vehicle 2 is calculated.

Specifically, the reliability calculation unit 112 acquires a reference value stored in advance in the reference value storage unit 122 . The reference value is a reference value for calculating the reliability, and includes a plurality of evaluation values (difference between the above-mentioned scheduled time and actual time, continuous running time of the vehicle 2, maximum acceleration/deceleration, variation in acceleration/deceleration, speed limit) is set for each. Then, the reliability calculation unit 112 calculates reliability by comparing each of the plurality of evaluation values acquired by the information acquisition unit 111 during transportation of the package with the reference value acquired from the reference value storage unit 122 .

The reliability calculation unit 112 calculates the reliability by converting the difference between each of the plurality of evaluation values and the reference value according to a predetermined rule. For example, if the difference between the evaluation value and the reference value is less than 10% of the reference value, the reliability calculation unit 112 sets the reliability to “○” (high), If it is , the reliability is set to "Δ" (intermediate), and if it is 50% or more of the reference value, the reliability is set to "X" (low). As a result, the reliability calculation unit 112 can calculate the reliability so that the larger the difference between the evaluation value and the reference value in the positive direction, the lower the reliability, and the smaller the difference, the higher the reliability.

The method by which the reliability calculation unit 112 calculates the reliability is not limited to the specific method shown here. The reliability calculation unit 112 may use the value itself of the difference between each of the plurality of evaluation values and the reference value as the reliability. Furthermore, the reliability calculation unit 112 may calculate one reliability by integrating the reliability calculated for each of the plurality of evaluation values according to a predetermined rule.

The reliability calculation unit 112 adds the reliability calculated by the reliability calculation unit 112 based on the evaluation value and the identification information of the driver to the evaluation value obtained by the information acquisition unit 111 during transportation of the package. Acquire the evaluation value D1. The driver's identification information is, for example, a user ID assigned to the driver who drives the vehicle 2 . When the driver and the vehicle 2 correspond one-to-one, the identification information of the driver may be the same as the identification information of the vehicle 2 . The reliability calculation unit 112 causes the evaluation value storage unit 121 to store an evaluation value D obtained by adding the new evaluation value D1 to the stored evaluation value D2 that has already been stored.

The transmitting unit 113 transmits a determination request including the stored evaluation value D2 and the evaluation value D indicating the new evaluation value D1 to the other information processing apparatuses 1B and 1C together with the identification information of the first information processing apparatus 1A. The identification information of the first information processing device 1A is information that can identify the first information processing device 1A, such as an ID and a serial number.

Although the processing performed in the second information processing device 1B will be described below, the same processing is performed in the third information processing device 1C. In the second information processing device 1B, the reception unit 114 receives the determination request from the first information processing device 1A.

The determination unit 115 compares the evaluation value D stored in the evaluation value storage unit 121 with the evaluation value D included in the determination request received by the reception unit 114, thereby determining whether the evaluation value D included in the determination request is illegal. Determine whether or not it has been rewritten.

Specifically, the determination unit 115 stores the stored evaluation value D2 of the evaluation value D stored in the evaluation value storage unit 121 and the stored evaluation value D2 of the evaluation value D included in the determination request received by the reception unit 114. Compare with At this time, the determination unit 115 may compare the stored evaluation value D2 itself, or may compare a hash value calculated according to a predetermined rule from the stored evaluation value D2. Further, the determination unit 115 may compare both the evaluation value and reliability included in the stored evaluation value D2, or may compare only the evaluation value included in the stored evaluation value D2.

If the stored evaluation value D2 of the evaluation value D stored in the evaluation value storage unit 121 matches the stored evaluation value D2 of the evaluation value D included in the determination request received by the reception unit 114, the determination unit 115 determines that the evaluation value D included in the determination request has not been rewritten. On the other hand, when the stored evaluation value D2 of the evaluation value D stored in the evaluation value storage unit 121 and the stored evaluation value D2 of the evaluation value D included in the determination request received by the reception unit 114 do not match , the determination unit 115 determines that the evaluation value D included in the determination request has been rewritten.

Storage control unit 116 stores evaluation value D included in the determination request (that is, driver identification The evaluation value associated with the information and the reliability calculated based on the evaluation value) are stored in the evaluation value storage unit 121 . At this time, the storage control unit 116 may store the entire evaluation value D included in the determination request in the evaluation value storage unit 121, or store only the new evaluation value D1 of the evaluation value D included in the determination request in the evaluation value storage unit 121. 121 may be added.

On the other hand, when the determination unit 115 determines that the evaluation value D included in the determination request received by the reception unit 114 has been rewritten, the storage control unit 116 stores the evaluation value D included in the determination request in the evaluation value storage unit 121 . is discarded without being stored in the At this time, the storage control unit 116 may transmit information indicating that the evaluation value D included in the determination request has been discarded to the other information processing device 1 .

In this way, each information processing device 1 of the vehicle information management system S stores the evaluation value D (stored evaluation value D2) already stored in the evaluation value storage unit 121 and the evaluation value D (stored evaluation value D2) included in the received determination request. By comparing with the completed evaluation value D2), it is determined whether or not the evaluation value D has been rewritten. As a result, even if the evaluation value D already stored in one information processing device 1 has been illegally rewritten, it will not be stored in another information processing device 1 .

The vehicle information management system S may record the evaluation value D using known blockchain technology. That is, the storage control unit 116 regards the new evaluation value D1 included in the determination request as one block, and combines the new evaluation value D1 included in the determination request with the blocks already stored in the evaluation value storage unit 121 to obtain the new evaluation value D1 included in the determination request. is added to the evaluation value storage unit 121 .

Specifically, the storage control unit 116 calculates a hash value and a nonce value that satisfy a predetermined condition based on blocks already stored in the evaluation value storage unit 121 and the new evaluation value D1 included in the determination request. do. Then, the storage control unit 116 connects the new evaluation value D1 to which the calculated hash value and nonce value are added to the block already stored in the evaluation value storage unit 121 and stores the new evaluation value D1 in the evaluation value storage unit 121 . Any of the three or more information processing apparatuses 1 may calculate the hash value and the nonce value.

In this way, when the evaluation value D is recorded using blockchain technology, it is necessary to recalculate the hash value of a series of past blocks in order to rewrite the already recorded evaluation value D. rewriting becomes more difficult.

In the present embodiment, the information processing device 1 that is the transmission source of the evaluation value calculates the reliability based on the evaluation value, but the information processing device 1 that is the transmission destination of the evaluation value calculates the reliability based on the evaluation value. You may In this case, when receiving the determination request, the information processing apparatus 1 calculates the reliability based on the evaluation value indicated by the determination request by the method described above.

Next, the information processing apparatus 1 accepts designation of driver selection conditions and weights from pre-registered users, selects a driver based on the reliability, and notifies the user of the reliability of the selected driver. A user is, for example, an operator of one of three or more information processing apparatuses 1 . When searching for a driver, the user designates a driver selection condition on the display unit 13 of the information processing device 1, and displays information on the selected driver.

FIG. 5 is a front view of the information processing device 1 displaying a condition designation screen for receiving designation of selection conditions by the driver. The condition specifying screen includes a condition column 131 for specifying a selection condition, a weight column 132 (important item column) for specifying a weight for an evaluation value, and a button 133 . The condition column 131 includes, for example, the date, the location of the transportation source of the package, and the location of the transportation destination.

The weight column 132 receives a weight for each of the plurality of evaluation values by allowing the user to select the evaluation value that the user attaches importance to among the plurality of evaluation values. For example, when the user wishes to request transportation of a fragile package such as a precision machine, the user specifies a small maximum acceleration/deceleration and a small amount of uneven operation in the weight column 132 . On the other hand, if the user wishes to request transportation of a package such as perishables whose deadline is important, the user specifies observance of the scheduled time in the weight column 132 . In the example of FIG. 5, the weight column 132 accepts weights for multiple evaluation values.

The button 133 is a virtual button (icon) that can be pressed by the user on the display unit 13 . The user presses the button 133 after specifying each item in the condition column 131 and the weight column 132 using the operation unit 14 . When the button 133 is pressed, the selection unit 117 receives the selection condition specified by the user in the condition column 131 and the weight specified in the weight column 132 .

Based on the evaluation value D stored in the evaluation value storage unit 121 and the operation schedule stored in the operation schedule storage unit 123, the selection unit 117 selects the vehicle 2 that satisfies the selection condition specified by the user. For example, the selection unit 117 selects the vehicle 2 whose operation route indicated by the operation schedule stored in the operation schedule storage unit 123 is close to the specified transportation source and transportation destination positions on the specified date.

Further, the selection unit 117 selects a predetermined number of drivers from among the drivers of the vehicle 2 who satisfy the selection conditions, based on the reliability with the weight specified by the user. For example, the selection unit 117 selects a predetermined number of drivers of the vehicle 2 who satisfy the selection condition in descending order of reliability corresponding to the evaluation values to which the weights specified by the user are set. The selection unit 117 may select a predetermined number of drivers in descending order of reliability from a plurality of weighted evaluation values.

The notification unit 118 notifies the user of the reliability of the driver selected by the selection unit 117 by displaying it on the display unit 13 in association with information on the driver.

FIG. 6 is a front view of the information processing device 1 displaying a notification screen for notifying the reliability of the selected driver. The notification screen includes driver information 134 and reliability 135 . The driver information 134 is stored in the operation schedule storage unit 123 as information about the vehicle 2 and the driver associated with the identification information of the driver selected by the selection unit 117 (for example, the vehicle registration number of the vehicle 2, the name of the driver, the telephone number, etc.).

The reliability 135 represents the reliability associated with the identification information of the driver selected by the selection unit 117 in the evaluation value storage unit 121 . As the reliability 135, the reliability itself stored in the evaluation value storage unit 121 may be displayed. may be displayed. Also, as the reliability 135, an evaluation value used for calculating the reliability may be displayed.

In this way, the vehicle information management system S accepts designation of an evaluation value to which the user attaches importance, and weights the reliability corresponding to the designated evaluation value, thereby selecting a highly reliable driver who is important to the user. to notify the user.

In the examples of FIGS. 5 and 6, the information processing apparatus 1 displays the search results based on the selection conditions and weights specified on the screen. The reliability of the driver may be automatically notified to the information processing device 1 of the user.

In the examples of FIGS. 5 and 6, the vehicle information management system S notifies any of the three or more information processing devices 1 of the reliability of the driver. The reliability of the driver may be notified to the terminal. In this case, the information terminal receives designation of selection conditions and weights from the user, and transmits the designated selection conditions and weights to any one of the three or more information processing apparatuses 1 . The selection unit 117 of the information processing device 1 selects a driver based on the selection conditions and weights received from the information terminal. The notification unit 118 notifies the user of the reliability of the driver selected by the selection unit 117 by transmitting it to the information terminal. As a result, the information processing device 1 can notify information terminals other than the information processing device 1 of the reliability of the driver.

As described above, the vehicle information management system S according to the present embodiment selects a driver who satisfies the conditions specified by the user based on the reliability of the driver whose reliability is enhanced by decentralized management, and the selected driver is selected. The user can be notified of the reliability of the driver.

[Flow chart of vehicle information management method]
FIG. 7 is a diagram showing a flowchart of a method for acquiring an evaluation value and reliability in a vehicle information management method (information processing method) executed by the vehicle information management system S according to this embodiment. While the vehicle 2 is transporting a package, in the information processing device 1 associated with the vehicle 2, the information acquisition unit 111 acquires an evaluation value indicating the quality of transportation of the package by the driver of the vehicle 2 (S11 ). The information acquisition unit 111 temporarily holds the acquired evaluation value.

When the vehicle 2 has not completed transportation of the package (NO in S12), the information acquisition unit 111 repeats acquisition of evaluation values. When the vehicle 2 has completed transportation of the package (YES in S12), the reliability calculation unit 112 calculates the evaluation value acquired by the information acquisition unit 111 during transportation of the package and the reference value storage unit 122 pre-stored. Based on the reference value, a reliability indicating the reliability of the transportation of the cargo by the driver of the vehicle 2 is calculated (S13).

The reliability calculation unit 112 obtains a new evaluation value obtained by adding the reliability calculated by the reliability calculation unit 112 based on the evaluation value and the identification information of the driver to the evaluation value obtained by the information obtaining unit 111 during transportation of the package. Get D1. The reliability calculation unit 112 causes the evaluation value storage unit 121 to store an evaluation value D obtained by adding the new evaluation value D1 to the stored evaluation value D2 that has already been stored.

The transmission unit 113 sends a determination request including the evaluation value D indicating the stored evaluation value D2 and the new evaluation value D1, with the identification information of the information processing device 1 (the first information processing device 1A in the example of FIG. 3) as the transmission source. together with the information processing device 1 (in the example of FIG. 3, the second information processing device 1B and the third information processing device 1C) (S14).

FIG. 8 is a diagram showing a flowchart of a method for storing and notifying evaluation values and reliability in the vehicle information management method (information processing method) executed by the vehicle information management system S according to this embodiment. The flowchart of FIG. 8 is executed in each of one or a plurality of information processing apparatuses 1 to which determination requests are sent.

The receiving unit 114 receives a determination request from another information processing device 1 (S21). The determination unit 115 compares the stored evaluation value D2 of the evaluation value D stored in the evaluation value storage unit 121 with the stored evaluation value D2 of the evaluation value D included in the determination request received by the reception unit 114 ( S22).

If the stored evaluation value D2 of the evaluation value D stored in the evaluation value storage unit 121 matches the stored evaluation value D2 of the evaluation value D included in the determination request received by the reception unit 114 (YES in S23 ), the determination unit 115 determines that the evaluation value D included in the determination request has not been rewritten (S24). Storage control unit 116 stores evaluation value D included in the determination request in evaluation value storage unit 121 on condition that determination unit 115 determines that evaluation value D included in the determination request received by reception unit 114 has not been rewritten. Store (S25).

If the stored evaluation value D2 of the evaluation value D stored in the evaluation value storage unit 121 and the stored evaluation value D2 of the evaluation value D included in the determination request received by the reception unit 114 do not match (S23 NO), the determination unit 115 determines that the evaluation value D included in the determination request has been rewritten (S26). The storage control unit 116 discards the evaluation value D included in the determination request without storing it in the evaluation value storage unit 121 .

When searching for a driver, the user specifies weights for driver selection conditions and evaluation values on the display unit 13 of the information processing device 1 . The selection unit 117 receives selection conditions and weights specified by the user (S27).

Based on the evaluation value D stored in the evaluation value storage unit 121 and the operation schedule stored in the operation schedule storage unit 123, the selection unit 117 selects the vehicle 2 that satisfies the selection condition specified by the user. Further, the selection unit 117 selects a predetermined number of drivers from among the drivers of the vehicle 2 who satisfy the selection conditions, based on the reliability with the weight specified by the user (S28).

The notification unit 118 notifies the user of the reliability of the driver selected by the selection unit 117 by displaying it on the display unit 13 in association with the information on the driver (S29).

In the exemplary flowchart of FIG. 8, the processing for storing the evaluation value and reliability and the processing for notifying the evaluation value and reliability are performed successively, but these processing may be performed independently. .

[Effect of this embodiment]
According to the vehicle information management system S according to the present embodiment, each information processing device 1 stores the evaluation value D (stored evaluation value D2) already stored in the evaluation value storage unit 121 and the evaluation included in the received determination request. By comparing with the value D (stored evaluation value D2), it is determined whether the evaluation value D has been rewritten.

Since multiple information processing apparatuses 1 distribute and manage the common evaluation value D, even if one subject or a third party illegally rewrites the evaluation value D stored in some of the information processing apparatuses 1, The rewritten evaluation value D is discarded without being stored in another information processing apparatus 1 . Therefore, the vehicle information management system S can select a driver based on the reliability indicated by the evaluation value D whose reliability has been enhanced by decentralized management, and notify the user of the reliability of the selected driver. can.

In addition, since advanced security measures are not required to prevent access from third parties, the cost is low. Further, even if the evaluation values D stored in some of the information processing apparatuses 1 are lost due to an accident or the like, the common evaluation values D are held in the other information processing apparatuses 1, so fault tolerance is high.

[Modification]
In the above description, all the information processing apparatuses 1 determine whether or not the evaluation value D has been illegally rewritten when storing the new evaluation value D1 included in the determination request in the evaluation value storage unit 121. In this modification, at least some of the information processing apparatuses 1 determine whether or not the evaluation value D has been illegally rewritten at a predetermined timing.

FIG. 9 is a schematic diagram of a vehicle information management method executed by the vehicle information management system S according to this modification. Differences from FIG. 3 will be mainly described below. In this modification, the information processing apparatuses 1A, 1B, and 1C store the received evaluation values D in the evaluation value storage unit 121 without determining whether or not they have been illegally rewritten. In this modification, the information processing apparatuses 1A, 1B, and 1C may receive the stored evaluation value D2 and the new evaluation value D1 and store them in the evaluation value storage unit 121, or may receive only the new evaluation value D1. may be additionally written in the evaluation value storage unit 121.

In the state of FIG. 9, the evaluation value storage unit 121 of each of the information processing apparatuses 1A, 1B, and 1C already stores the evaluation value D indicating the stored evaluation value D2 and the new evaluation value D1.

In at least one information processing device 1 (the second information processing device 1B in the example of FIG. 9) among the three or more information processing devices 1, the receiving unit 114 receives the evaluation value D from the other information processing devices 1A and 1C. receive a decision request containing Receiving unit 114 may periodically receive determination requests from other information processing apparatuses 1A and 1C, or may receive determination requests from other information processing apparatuses 1A and 1C at the timing when determination unit 115 performs determination. may

When the current time satisfies a predetermined condition (once a day, once a month, etc.), or when a predetermined instruction is received from the user (that is, the operator of the information processing apparatus 1), the determination unit 115 By comparing the evaluation value D stored in the evaluation value storage unit 121 and the evaluation value D included in the determination request received from each of the other information processing apparatuses 1A and 1C, the evaluation value D included in the determination request is rewritten. Determine whether or not A specific determination method is the same as the method described with reference to FIG. Furthermore, the determination unit 115 compares the evaluation values D included in the determination requests received from the plurality of information processing apparatuses 1A and 1C to determine whether or not the evaluation values D included in the determination requests have been rewritten. good too.

As described above, in the vehicle information management system S according to the present modification, at least some of the information processing devices 1 determine whether or not the evaluation value D has been illegally rewritten at a predetermined timing. Therefore, each information processing apparatus 1 does not need to determine whether or not the evaluation value D has been illegally rewritten each time it receives the evaluation value D, so the processing load for determination can be reduced.

Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of the gist thereof. be.
