[Technical Field]

[0001] The present invention relates to an information processing device, a program, and an information processing method. [Background technology]

[0002] In recent years, battery-powered vehicles have become popular, and many of these vehicles are being sold on the market as used cars. Patent Document 1 discloses a technology for appraising used cars based on input information. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-357256 Summary of the Invention [Problem to be solved by the invention]

[0004] The condition of a vehicle can be calculated as an assessed price by using the technology disclosed in Patent Document 1. However, because the desired condition of a vehicle differs depending on the intended use of the vehicle by the vehicle user, there is a problem in that even if the condition of a vehicle is calculated using the above technology, it is not clear whether the vehicle can be used for the intended purpose of the vehicle user.

[0005] The present invention has been made in view of these points, and has as an object, for example, to evaluate whether a vehicle can be used for a predetermined purpose. [Means for solving the problem]

[0006] An information processing device according to a first aspect of the present invention includes an acquisition unit that acquires information indicating the usage history of a battery-powered vehicle; a history identification unit that identifies the usage history of the battery based on the usage history; an estimation unit that estimates the degree of deterioration of the battery of the current vehicle and the degree of deterioration of a body of the current vehicle that is composed of multiple components other than the battery based on the usage history of the vehicle and the usage history of the battery; an evaluation unit that evaluates whether the vehicle can be used for a specified purpose based on the degree of deterioration of the battery and the degree of deterioration of the body estimated by the estimation unit; and an output unit that outputs the evaluation result evaluated by the evaluation unit.

[0007] The estimation unit may estimate the current degree of deterioration of the body based on the period of use during which the vehicle has been used as indicated by the vehicle usage history and the purpose of the vehicle as identified by the vehicle usage history. The estimation unit may estimate a current degree of deterioration of the body based on a result of multiplying the period of use by the predetermined coefficient corresponding to the purpose of the vehicle.

[0008] The estimation unit may refer to data correlating the use of the vehicle, a body deterioration coefficient corresponding to the body, and a battery deterioration coefficient corresponding to the battery, and estimate the degree of deterioration of the body by multiplying the period of use by the body deterioration coefficient associated with the use of the vehicle identified by the vehicle usage history, and may estimate the degree of deterioration of the battery by multiplying the period of use by the battery deterioration coefficient associated with the use of the vehicle identified by the vehicle usage history.

[0009] The estimation unit may refer to data associating the use of the vehicle with component deterioration coefficients corresponding to each of multiple components other than the battery that make up the vehicle, and estimate the degree of deterioration of the body by adding up the results of calculating the degree of deterioration of each of the multiple components based on the period of use and the component deterioration coefficients associated with the use of the vehicle identified by the vehicle's usage history.

[0010] The estimation unit may refer to first data that associates the use of the vehicle with a plurality of actions by the driver of the vehicle that affect the deterioration of any of the plurality of components, and second data that associates each of the plurality of actions with the component deterioration coefficient for each of the plurality of components, and estimate the degree of deterioration of the body by summing up the results of multiplying, for each of the plurality of components, the period of use and the component deterioration coefficient corresponding to the action in the use of the vehicle identified by the vehicle's usage history.

[0011] The evaluation unit may evaluate the vehicle as usable for the specified purpose for the specified period if the battery degradation value estimated by the estimation unit, which increases as the degree of degradation of the battery increases, is less than a first threshold value, and if the body degradation value estimated by the estimation unit, which increases as the degree of degradation of the body increases, is less than a second threshold value, and may evaluate the vehicle as unusable for the specified purpose if at least one of the following conditions is met: the battery degradation value is equal to or greater than the first threshold value, or the body degradation value is equal to or greater than the second threshold value.

[0012] If the evaluation unit evaluates that the vehicle cannot be used for the specified purpose within the specified period, and if the battery deterioration value is equal to or greater than the first threshold value and the body deterioration value is less than the second threshold value, the evaluation unit may evaluate that the vehicle can be used for the specified purpose by replacing the battery.

[0013] When the evaluation unit evaluates that the vehicle cannot be used for the specified purpose, if the battery deterioration value is less than the first threshold value and the body deterioration value is equal to or greater than the second threshold value, the evaluation unit may evaluate that the battery can be used as a battery for another of the vehicles.

[0014] The information processing device may further have a use identification unit that, when the evaluation unit evaluates that the vehicle can be used for the specified purpose, identifies the number of times each of a plurality of components of the vehicle has been used based on the usage history of the vehicle, and if any of the identified plurality of components has been used more than a threshold value set for each component of the vehicle, identifies a use of the vehicle for which the overused component has been used less frequently, and the output unit may further output the use of the vehicle identified by the use identification unit.

[0015] A program according to a second aspect of the present invention causes a computer to function as an acquisition unit that acquires information indicating the usage history of a battery-powered vehicle; an identification unit that identifies the usage history of the battery based on the usage history; an estimation unit that estimates the degree of deterioration of the battery of the current vehicle and the degree of deterioration of the body of the current vehicle, which is composed of multiple components other than the battery, based on the usage history of the vehicle and the usage history of the battery; an evaluation unit that evaluates whether the vehicle can be used for a specified purpose for a specified period of time based on the degree of deterioration of the battery and the degree of deterioration of the body estimated by the estimation unit; and an output unit that outputs the evaluation result evaluated by the evaluation unit.

[0016] An information processing method according to a third aspect of the present invention includes the steps of: acquiring information indicating the usage history of a battery-powered vehicle, executed by a computer; identifying the usage history of the battery based on the usage history; estimating the degree of deterioration of the battery of the current vehicle and the degree of deterioration of a body of the current vehicle composed of multiple components other than the battery based on the usage history of the vehicle and the usage history of the battery; evaluating whether the vehicle can be used for a specified purpose within a specified period of time based on the estimated degree of deterioration of the battery and the estimated degree of deterioration of the body; and outputting the evaluation results. [Effects of the Invention]

[0017] According to the present invention, for example, it is possible to evaluate whether or not a vehicle can be used for a predetermined purpose. [Brief explanation of the drawings]

[Figure 6] 10 is a flowchart showing a flow of processing by the information processing device. DETAILED DESCRIPTION OF THE INVENTION

[0019] [Outline of Information Processing System S] FIG. 1 is a diagram for explaining an overview of an information processing system S. The information processing system S is a system used to provide an information provision service to a user. The information provision service is a service that provides evaluation information. The evaluation information is information that indicates the evaluation results of whether or not a vehicle V can be used for a specified purpose. The user is the manager of the vehicle V, for example, a leasing company that leases the vehicle V to a user. The information processing system S has a vehicle V, an information processing device 1, and an external terminal 2.

[0020] Vehicle V is an electric vehicle powered by battery E, and includes battery E and body B. Battery E is, for example, a lithium-ion secondary battery. Body B is made up of multiple components other than battery E, such as doors, seats, and tires. Note that vehicle V is not limited to an electric vehicle, and may also be a plug-in hybrid vehicle (hereinafter referred to as a "PHEV (Plug-in Hybrid Electric Vehicle)") that has a motor powered by battery E and an engine that runs on fuel such as gasoline.

[0021] The vehicle V has various sensors for collecting historical data and a communication unit for connecting to the network N, and transmits the historical data collected by the various sensors to an information processing device 1 (described later) via the communication unit. The historical data is information indicating the usage history of the vehicle V.

[0022] The information processing device 1 is a computer that provides evaluation information. The information processing device 1 manages information about a vehicle V managed by a user.

[0023] The external terminal 2 is a terminal used by a user. The external terminal 2 is, for example, a smartphone, a personal computer, or a car navigation system of a vehicle V. The external terminal 2 displays the evaluation information provided by the information processing device 1 in response to a request for evaluation information.

[0024] When a vehicle V used by a user is returned after the usage period (e.g., lease period) has expired, the user inspects the vehicle V and determines whether the vehicle V can be leased again. However, even if the vehicle V is inspected, it is difficult to determine the extent of unseen deterioration, making it difficult to determine whether the vehicle V can be leased again. Therefore, the information processing system S estimates the degree of deterioration of the vehicle V based on the historical data of the vehicle V, and evaluates whether the vehicle V can be used for a specified purpose based on the estimated degree of deterioration of the vehicle V.

[0025] Specifically, first, the information processing device 1 acquires historical data of the vehicle V to be evaluated, and then estimates the degree of deterioration of the battery E and the degree of deterioration of the body B as the degree of deterioration of the vehicle V based on the usage history of the vehicle V indicated by the historical data. The information processing device 1 evaluates whether the vehicle V can be used for a predetermined purpose based on the estimated degree of deterioration of the battery E and the degree of deterioration of the body B. The predetermined purpose is, for example, the purpose for which the desired condition of the vehicle V is the lowest (for example, a private car among a private car, a public car, and a logistics delivery vehicle) out of multiple purposes for which the vehicle V can be used (for example, a private car among a private car, a public car, and a logistics delivery vehicle).

[0026] Then, the information processing device 1 transmits evaluation information indicating the evaluation result of the vehicle V to the external terminal 2. After that, when the external terminal 2 acquires the evaluation information, it displays the evaluation information.

[0027] In this way, the information processing system S can evaluate whether the vehicle can be used for a predetermined purpose. This allows the user to determine whether the vehicle V can be leased again. As a result, the user can provide the user with a vehicle V that suits the user's purpose. The configuration of the information processing device 1 will be described below.

[0028] [Configuration of information processing device 1] 2 is a diagram showing the configuration of information processing device 1. Information processing device 1 has a communication unit 11, a storage unit 12, and a control unit 13. Control unit 13 has a reception unit 131, an acquisition unit 132, a history identification unit 133, an estimation unit 134, an evaluation unit 135, a use identification unit 136, and an output unit 137.

[0029] The communication unit 11 is an interface for connecting to the network N, and is configured to include, for example, a LAN (Local Area Network) controller. The storage unit 12 is a storage medium such as a ROM (Read Only Memory), a RAM (Random Access Memory), or a hard disk. The storage unit 12 stores a program executed by the control unit 13.

[0030] The memory unit 12 stores information for identifying the vehicle V managed in the information provision service. The information for identifying the vehicle V includes, for example, vehicle identification information for identifying the vehicle V. The memory unit 12 stores information about the vehicle V managed by the user. The information about the vehicle V includes at least vehicle identification information for identifying the vehicle V. The memory unit 12 stores a coefficient management database that manages coefficients used to estimate the degree of deterioration of the vehicle V. Details of the coefficient management database will be described later.

[0031] The control unit 13 is, for example, a CPU (Central Processing Unit). The control unit 13 executes the programs stored in the storage unit 12, thereby functioning as a reception unit 131, an acquisition unit 132, a history identification unit 133, an estimation unit 134, an evaluation unit 135, a use identification unit 136, and an output unit 137.

[0032] The receiving unit 131 receives a request for providing evaluation information of the vehicle V from the external terminal 2. The request for providing includes vehicle identification information.

[0033] The acquisition unit 132 acquires history data indicating the usage history of the vehicle V. The history data includes, for example, location information, the number of times the battery E has been charged (the number of times rapid charging and the number of times normal charging), the number of times the vehicle has suddenly started, the number of times the doors have been opened and closed, the number of times the seat has been reclined, etc. The location information is, for example, position coordinates indicating the position of the vehicle V, and each position coordinate is associated with the measurement time at which the position coordinates were measured.

[0034] For example, when the receiving unit 131 receives a provision request, the acquiring unit 132 acquires history data of the vehicle V identified by the vehicle identification information included in the provision request. The acquiring unit 132 may acquire the history data at predetermined intervals (for example, hourly, daily, monthly, etc.) during the usage period. For example, the acquiring unit 132 acquires the history data from the vehicle V. The acquiring unit 132 may acquire the history data from a server (not shown) managed by the manufacturer of the vehicle V.

[0035] The history identification unit 133 identifies the usage history of the battery E based on the usage history of the vehicle V indicated by the history data acquired by the acquisition unit 132. The usage history of the battery E includes, for example, information indicating the number of discharge and charge cycles of the battery E, temperature information of the battery E, etc.

[0036] The information indicating the number of discharge and charge cycles of battery E includes, for example, a discharging period and a charging period, but is not limited to this and may further include the amount of discharged power and the amount of charged power. For example, the memory unit 12 stores the number of discharge and charge cycles of battery E per unit traveling distance (for example, 1 kilometer) for each speed of vehicle V. In this case, first, the history identification unit 133 identifies the traveling distance traveled by vehicle V and the speed of vehicle V at which the traveling distance was traveled, based on the position information included in the history information of vehicle V. Then, the history identification unit 133 identifies the number of discharge and charge cycles of battery E based on the identified traveling distance and the identified speed.

[0037] The temperature information of battery E is information indicating changes in the temperature of battery E. For example, the storage unit 12 stores the rate of increase in battery E per unit time (e.g., per minute, per hour, etc.) for each number of discharge and charge cycles of battery E. In this case, the history determination unit 133 determines changes in the temperature of battery E based on the air temperature at the position of vehicle V specified by the position information and the specified number of discharge and charge cycles of battery E. The history determination unit 133 obtains information indicating the air temperature at the position of vehicle V specified by the position information from, for example, a server (not shown) that manages weather forecasts.

[0038] The estimation unit 134 estimates the current degree of deterioration of the battery E of the vehicle V and the current degree of deterioration of the body B based on the usage history of the vehicle V indicated by the history data acquired by the acquisition unit 132 and the usage history of the battery E identified by the history identification unit 133. The degree of deterioration of the battery E and the degree of deterioration of the body B are indicated, for example, by numerical values ​​that indicate larger values ​​as the degree of deterioration increases.

[0039] The estimation unit 134 may estimate the degree of deterioration of battery E based on the number of discharge and charge cycles of battery E included in the usage history of battery E identified by the history identification unit 133. Battery E has an appropriate temperature range (for example, a range from 16°C to 25°C), and when the temperature of battery E exceeds at least the appropriate temperature range, deterioration of battery E progresses. For example, the greater the number of discharge and charge cycles of battery E, that is, the higher the density of discharge and charge in a certain period, the greater the degree of heat generation may be. Therefore, the estimation unit 134 estimates the degree of deterioration of battery E to be higher the greater the number of discharge and charge cycles, and estimates the degree of deterioration of battery E to be lower the fewer the number of discharge and charge cycles.

[0040] The estimation unit 134 may estimate the degree of deterioration of battery E based on the number of times battery E has been charged, which is included in the history data. For example, when battery E is charged by rapid charging, the degree of heat generation may be higher when battery E is charged by normal charging than when battery E is charged by fast charging. Therefore, the estimation unit 134 estimates the degree of deterioration of battery E to be higher the more times battery E has been fast charged, and estimates the degree of deterioration of battery E to be lower the less times battery E has been fast charged.

[0041] The estimation unit 134 may estimate the degree of deterioration of battery E based on the temperature information of battery E included in the usage history of battery E identified by the history identification unit 133. For example, the estimation unit 134 estimates the degree of deterioration of battery E to be higher the longer the period in which the temperature exceeds the appropriate temperature range, and estimates the degree of deterioration of battery E to be lower the shorter the period in which the temperature exceeds the appropriate temperature range.

[0042] The estimation unit 134 may estimate the degree of deterioration of the body B based on the travel distance of the vehicle V identified by the history data. For example, the estimation unit 134 estimates the degree of deterioration of the body B to be higher the longer the travel distance of the vehicle V, and estimates the degree of deterioration of the body B to be lower the shorter the travel distance of the vehicle V.

[0043] The estimation unit 134 may estimate the degree of deterioration of each component of the vehicle V based on the usage history of the vehicle V, and estimate the degree of deterioration of the body B based on the estimated degree of deterioration of each component. For example, first, the estimation unit 134 estimates the degree of deterioration of each component to be higher the greater the number of times each component operates (for example, the number of times a door is opened and closed and the number of times a seat is reclined, etc.), and estimates the degree of deterioration of each component to be lower the fewer the number of times each component operates. Then, the estimation unit 134 estimates the degree of deterioration of the body B by summing up the numerical values ​​indicating the estimated degree of deterioration of each component.

[0044] The estimation unit 134 may estimate the current degree of deterioration of the body B based on the usage period during which the vehicle V has been used, which is indicated by the usage history of the vehicle V, and the purpose of the vehicle V, which is identified by the usage history of the vehicle V. Specifically, the estimation unit 134 first identifies the purpose of the vehicle V based on the usage history of the vehicle V. Then, the estimation unit 134 estimates the degree of deterioration of the body B when the vehicle V is used for the identified purpose during the usage period of the vehicle V.

[0045] For example, a vehicle V used as a "logistics delivery vehicle" has a long mileage. Therefore, when the mileage of the vehicle V identified by the location information included in the history data is equal to or greater than a predetermined threshold, the estimation unit 134 determines that the use of the vehicle V is a "logistics delivery vehicle." Furthermore, for example, a vehicle V used as a "public vehicle" is frequently used during the daytime on weekdays. Therefore, when the frequency of use of the vehicle V on weekdays identified by the location information included in the history data is equal to or greater than a predetermined threshold, the estimation unit 134 determines that the use of the vehicle V is a "public vehicle." Note that information indicating the use of the vehicle V may be included in the history data in advance, or may be included in the provision request received by the reception unit 131.

[0046] The memory unit 12 stores, for example, a predetermined coefficient for each use of the vehicle V. The predetermined coefficient is, for example, a numerical value indicating the degree of deterioration of the body B per unit period (e.g., one day, one month, etc.). In this case, the estimation unit 134 estimates the current degree of deterioration of the body B based on the predetermined coefficient corresponding to the identified use of the vehicle V. Specifically, the estimation unit 134 estimates the current degree of deterioration of the body B based on the result of multiplying the usage period of the vehicle V by the predetermined coefficient corresponding to the use of the vehicle V identified by the usage history of the vehicle V.

[0047] For example, suppose the predetermined coefficient corresponding to the use of a certain vehicle V is "5," the unit period of the predetermined coefficient is "1 month," and the period of use of the vehicle V is "12 months." In this case, the estimation unit 134 estimates "60," which is the result of multiplying the period of use "12 months" by the predetermined coefficient "5," as the current degree of deterioration of the body B. In this way, the information processing device 1 can estimate the degree of deterioration of the body B according to the use of the vehicle V.

[0048] The estimation unit 134 may estimate the degree of deterioration of the body B based on a predetermined coefficient corresponding to each component of the vehicle V. Fig. 3 is a diagram showing an example of the configuration of a coefficient management database. The coefficient management database shown in Fig. 3 stores, for each use of the vehicle V, the use of the vehicle V and component deterioration coefficients (doors, seats, etc.) corresponding to each of multiple components other than the battery that constitute the vehicle V, in association with each other.

[0049] In this case, the estimation unit 134 refers to the coefficient management database and estimates the degree of deterioration of the body B by adding up the results of calculating the degree of deterioration of each of multiple components based on the period of use of the vehicle V and the component deterioration coefficient associated with the use of the vehicle V.

[0050] For example, suppose that the use of a certain vehicle V is "official vehicle," the unit period of the component deterioration coefficient is "1 month," and the period of use of vehicle V is "12 months." In this case, first, the estimation unit 134 multiplies each component deterioration coefficient associated with the use of vehicle V as "official vehicle" in the counting management database by the period of use of vehicle V, "12 months," to calculate a deterioration degree of "36" for the door and a deterioration degree of "24" for the seat. Then, the estimation unit 134 estimates the deterioration degree of body B as "60," which is the sum of the calculated deterioration degrees of each component. In this way, the information processing device 1 can improve the accuracy of estimating the deterioration degree of body B.

[0051] The estimation unit 134 may refer to a behavior management database that manages the behaviors that the driver of the vehicle V can take depending on the use of the vehicle V, and a coefficient management database, and estimate the degree of deterioration of the body B based on predetermined behaviors identified by the use of the vehicle V.

[0052] FIG. 4 is a diagram showing an example of a database stored in the storage unit 12. The behavior management database shown in FIG. 4(a) stores first data associating the use of the vehicle V with an influencing behavior. An influencing behavior is a behavior by the driver of the vehicle V that affects the deterioration of one of multiple components. For example, when the driver takes the behavior of using the seat reclining function, this affects the deterioration of the seat. Also, for example, when the driver takes the behavior of opening and closing the door to load or unload cargo in the vehicle V, this affects the deterioration of the door. The coefficient management database shown in FIG. 4(b) stores second data associating each of multiple influencing behaviors with a component deterioration coefficient for each of multiple components.

[0053] In this case, the estimation unit 134 refers to the behavior management database and the coefficient management database, and estimates the degree of deterioration of the body B by summing the results of multiplying the period of use of the vehicle V by the component deterioration coefficient corresponding to the driver's behavior in the use of the vehicle V for each of the multiple components.

[0054] For example, suppose the use of a certain vehicle V is a "logistics delivery vehicle," the unit period for each component deterioration coefficient is "1 month," and the usage period of vehicle V is "12 months." In this case, first, the estimation unit 134 identifies "loading and unloading cargo" and "using the seat reclining function," which are associated with the use of vehicle V as a "logistics delivery vehicle" in the behavior management database, as influencing behaviors. The estimation unit 134 multiplies the usage period of vehicle V, "12 months," by the component deterioration coefficient for the door, "5," which is associated with the identified influencing behavior, "loading and unloading cargo," in the coefficient management database, to calculate a deterioration degree of "60" for the door.

[0055] Furthermore, the estimation unit 134 calculates the degree of deterioration of the seat as "36" by multiplying the period of use of the vehicle V, "12 months," by the seat component deterioration coefficient of "3," which is associated with the identified influencing behavior "use of the seat reclining function," in the coefficient management database. Then, the estimation unit 134 estimates the degree of deterioration of the body B as "96," which is the sum of the degree of deterioration of the door, "60," and the degree of deterioration of the seat, "36." In this way, the information processing device 1 can estimate the degree of deterioration of the body B according to the behavior of the driver that is expected when the vehicle V is used for the intended purpose of the vehicle V.

[0056] The estimation unit 134 may estimate the degree of deterioration of the body B using a component deterioration coefficient that is varied according to the frequency of use of the component. For example, the estimation unit 134 sets a larger value for the component deterioration coefficient of the seat stored in the coefficient management database as the number of times the seat reclining function is operated included in the history information of the vehicle V increases. The estimation unit 134 may set a larger value for the component deterioration coefficient of the seat stored in the coefficient management database when the number of times the seat reclining function is operated included in the history information of the vehicle V is equal to or greater than a preset threshold. On the other hand, the estimation unit 134 sets a smaller value for the component deterioration coefficient of the seat stored in the coefficient management database as the number of times the seat reclining function is operated included in the history information of the vehicle V decreases.

[0057] The estimation unit 134 may estimate the degree of deterioration of the body B and the deterioration coefficient of the battery E based on the period of use of the vehicle V and the purpose of the vehicle V. The body deterioration coefficient is a predetermined coefficient corresponding to the body B. The battery deterioration coefficient is a predetermined coefficient corresponding to the battery E.

[0058] Fig. 5 is a diagram showing an example of the configuration of the coefficient management database. The coefficient management database shown in Fig. 5 stores, for each use of vehicle V, the use of vehicle V, a body deterioration coefficient corresponding to body B, and a battery deterioration coefficient corresponding to battery E in association with each other. In this case, the estimation unit 134 refers to the coefficient management database and estimates the degree of deterioration of body B by multiplying the usage period of vehicle V by the body deterioration coefficient, and estimates the degree of deterioration of battery E by multiplying the usage period of vehicle V by the battery deterioration coefficient.

[0059] For example, suppose the use of a certain vehicle V is a "public vehicle," the unit period of each deterioration coefficient is "1 month," and the period of use of vehicle V is "12 months." In this case, first, the estimation unit 134 calculates a deterioration degree of "36" for body B by multiplying the period of use of vehicle V ("12 months") by the body deterioration coefficient of "3" associated with the use of vehicle V ("public vehicle") in the coefficient management database. The estimation unit 134 also calculates a deterioration degree of "12" for battery E by multiplying the period of use of vehicle V ("12 months") by the battery deterioration coefficient of "1" associated with the use of vehicle V ("public vehicle") in the coefficient management database. In this way, the information processing device 1 can estimate the deterioration degrees of battery E and body B according to the use of vehicle V.

[0060] The estimation unit 134 may estimate the degree of deterioration of battery E using a battery deterioration coefficient that is varied according to the usage history of battery E identified by the history identification unit 133. For example, the estimation unit 134 sets the battery deterioration coefficient to a larger value the greater the number of discharge / charge cycles, the greater the number of times rapid charging of battery E, or the longer the period in which battery E is above the appropriate temperature range. On the other hand, the estimation unit 134 sets the battery deterioration coefficient to a smaller value the fewer the number of discharge / charge cycles, the fewer the number of times rapid charging of battery E, or the shorter the period in which battery E is above the appropriate temperature range.

[0061] If the vehicle V is a PHEV, the estimation unit 134 may further estimate the degree of engine deterioration. The memory unit 12 stores, for example, an engine deterioration coefficient for each use of the vehicle V. The engine deterioration coefficient is, for example, a numerical value indicating the degree of engine deterioration per unit period (e.g., one day, one month, etc.). In this case, the estimation unit 134 estimates the current degree of engine deterioration based on a predetermined coefficient corresponding to the identified use of the vehicle V. Specifically, the estimation unit 134 estimates the current degree of engine deterioration based on the result of multiplying the usage period of the vehicle V by a predetermined coefficient corresponding to the use of the vehicle V identified by the usage history of the vehicle V.

[0062] The evaluation unit 135 evaluates whether or not the vehicle V can be used for a predetermined purpose based on the degree of deterioration of the battery E and the degree of deterioration of the body B estimated by the estimation unit 134. Specifically, the evaluation unit 135 evaluates whether or not the vehicle V can be used for a predetermined purpose for a predetermined period based on the relationship between a battery deterioration numerical value indicating the degree of deterioration of the battery E estimated by the estimation unit 134, a body deterioration numerical value indicating the degree of deterioration of the body B estimated by the estimation unit 134, and a predetermined threshold value.

[0063] The battery deterioration numerical value is a numerical value that increases as the degree of deterioration of the battery E estimated by the estimation unit 134 increases. The body deterioration numerical value is a numerical value that increases as the degree of deterioration of the body estimated by the estimation unit 134 increases. The predetermined threshold value is set in advance in the information processing device 1, and is determined, for example, based on the relationship between the maintenance costs incurred according to the degree of deterioration of the vehicle V and the compensation that the user will receive by leasing the vehicle V.

[0064] More specifically, if the battery degradation value is less than a first threshold and the body degradation value is less than a second threshold, the evaluation unit 135 evaluates that the vehicle V can be used for a predetermined purpose for a predetermined period of time. The first threshold is a predetermined threshold corresponding to the battery degradation value. The second threshold is a predetermined threshold corresponding to the body degradation value. For example, the predetermined period is the shortest period for which leasing is possible (e.g., one month, one year, etc.). On the other hand, if the battery degradation value is equal to or greater than the first threshold or the body degradation value is equal to or greater than the second threshold, the evaluation unit 135 evaluates that the vehicle V cannot be used for the predetermined purpose. In this way, the information processing device 1 can prevent vehicles V that are in a working condition but cannot be used for the predetermined purpose from being distributed.

[0065] When the evaluation unit 135 evaluates that the vehicle V cannot be used for a predetermined purpose within a predetermined period of time, the evaluation unit 135 may evaluate whether the vehicle V can be used for the predetermined purpose under predetermined conditions. Specifically, when the evaluation unit 135 evaluates that the vehicle V cannot be used for the predetermined purpose within a predetermined period of time, if the battery degradation numerical value is equal to or greater than a first threshold and the body degradation numerical value is less than a second threshold, the evaluation unit 135 evaluates that the vehicle V can be used for the predetermined purpose by replacing the battery E. On the other hand, when the evaluation unit 135 evaluates that the vehicle V cannot be used for the predetermined purpose within a predetermined period of time, if the battery degradation numerical value is less than the first threshold and the body degradation numerical value is less than the second threshold, the evaluation unit 135 evaluates that the vehicle V cannot be used for the predetermined purpose even if the battery E is replaced.

[0066] Even if the evaluation unit 135 evaluates that the vehicle V cannot be used for a predetermined purpose within a predetermined period of time, if the deterioration levels of the battery E and the body satisfy predetermined conditions, the evaluation unit 135 may evaluate whether the vehicle V can be used for another purpose. Specifically, if the evaluation unit 135 evaluates that the vehicle V cannot be used for a predetermined purpose and the battery deterioration numerical value is less than a first threshold and the body deterioration numerical value is equal to or greater than a second threshold, the evaluation unit 135 evaluates that the battery E can be used as the battery E for another vehicle V. On the other hand, if the evaluation unit 135 evaluates that the vehicle V cannot be used for a predetermined purpose and at least the battery deterioration numerical value is less than the first threshold, the evaluation unit 135 evaluates that the battery E cannot be used as the battery E for another vehicle V.

[0067] If the estimation unit 134 further estimates the degree of engine deterioration, the evaluation unit 135 further evaluates whether the vehicle V can be used for a predetermined purpose within a predetermined period of time based on an engine deterioration numerical value indicating the degree of engine deterioration. For example, if the battery deterioration numerical value is less than a first threshold, the body deterioration numerical value is less than a second threshold, and the engine deterioration numerical value is less than a third threshold, the evaluation unit 135 evaluates that the vehicle V can be used for a predetermined purpose within a predetermined period of time. The third threshold is a predetermined threshold value corresponding to the engine deterioration numerical value. On the other hand, if the engine deterioration numerical value is equal to or greater than the third threshold, the evaluation unit 135 evaluates that the vehicle V cannot be used for a predetermined purpose.

[0068] The output unit 137 outputs evaluation information indicating the evaluation result obtained by the evaluation unit 135. The output unit 137 transmits the evaluation information to, for example, the external terminal 2 from which the receiving unit 131 has received the provision request.

[0069] When the evaluation unit 135 evaluates that the vehicle V can be used for a predetermined purpose, the output unit 137 may further output information indicating a purpose suitable for the vehicle V. Specifically, first, when the evaluation unit 135 evaluates that the vehicle V can be used for a predetermined purpose, the purpose identification unit 136 identifies the number of times each of multiple components of the vehicle V has been used based on the usage history of the vehicle V. When there are overused components of the vehicle V that exceed a threshold value set for each component of the vehicle V among the identified multiple components, the purpose identification unit 136 identifies a purpose of the vehicle V for which the overused components have been used less frequently. Then, the output unit 137 further outputs the purpose of the vehicle V identified by the purpose identification unit 136.

[0070] For example, when the vehicle V is used as a "logistics delivery vehicle," if the number of times the door is opened and closed exceeds the threshold value corresponding to the door among the number of times the door is opened and closed and the number of times the seat is reclined, the use identification unit 136 identifies a use of the vehicle V in which the door is opened and closed less frequently (for example, a use other than a logistics delivery vehicle, such as a private car or a public car). In this way, the information processing device 1 can extend the time when the vehicle V cannot be used for the specified use, i.e., the lifetime of the vehicle V.

[0071] [Processing of information processing device 1] Next, a description will be given of the processing flow of the information processing device 1. Fig. 6 is a flowchart showing the processing flow of the information processing device 1. This processing starts when the receiving unit 131 receives a provision request including vehicle identification information from the external terminal 2 (S1).

[0072] The acquisition unit 132 acquires history data of the vehicle V identified by the vehicle identification information included in the provision request accepted by the acceptance unit 131 (S2). The history identification unit 133 identifies the usage history of the battery E based on the usage history of the vehicle V indicated by the history data acquired by the acquisition unit 132 (S3).

[0073] The estimation unit 134 estimates the current degree of deterioration of the battery E of the vehicle V and the current degree of deterioration of the body B based on the usage history of the vehicle V indicated by the historical data acquired by the acquisition unit 132 and the usage history of the battery E identified by the history identification unit 133 (S4).

[0074] The evaluation unit 135 evaluates whether the vehicle V can be used for a predetermined purpose based on the degree of deterioration of the battery E and the degree of deterioration of the body B estimated by the estimation unit 134. Specifically, the evaluation unit 135 determines whether the battery deterioration numerical value is less than a first threshold value and the body deterioration numerical value is less than a second threshold value (S5).

[0075] If the evaluation unit 135 determines that the battery degradation numerical value is less than the first threshold and that the body degradation numerical value is less than the second threshold (YES in S5), it evaluates that the vehicle V can be used for a predetermined purpose for a predetermined period of time (S6). On the other hand, if the evaluation unit 135 determines that the battery degradation numerical value is less than the first threshold and that the body degradation numerical value is not less than the second threshold (NO in S5), it determines whether the battery degradation numerical value is less than the first threshold (S7).

[0076] If the evaluation unit 135 determines that the battery degradation numerical value is less than the first threshold value (YES in S7), it evaluates that the battery E can be used as the battery E of another vehicle V (S8). On the other hand, if the evaluation unit 135 determines that the battery degradation numerical value is not less than the first threshold value (NO in S7), it determines whether the body degradation numerical value is less than the second threshold value (S9).

[0077] If the evaluation unit 135 determines that the body deterioration numerical value is less than the second threshold value (YES in S9), it evaluates that the vehicle V can be used for the predetermined purpose under a predetermined condition (replacing the battery E) (S10). On the other hand, if the evaluation unit 135 determines that the body deterioration numerical value is not less than the second threshold value (NO in S9), it evaluates that the battery E cannot be used as the battery E of another vehicle V, and that the vehicle V cannot be used for the predetermined purpose even if the battery E is replaced (S11). Then, the output unit 137 outputs evaluation information indicating the evaluation result evaluated by the evaluation unit 135 (S12).

[0078] [Effects of this embodiment] As described above, the information processing device 1 estimates the degree of deterioration of the battery E and the degree of deterioration of the body B based on the usage history of the vehicle V indicated by the historical data, and evaluates whether the vehicle V can be used for a predetermined purpose based on the estimated degree of deterioration of the battery E and the degree of deterioration of the body B. In this way, the information processing device 1 can evaluate whether the vehicle can be used for a predetermined purpose. This allows the user to determine whether the vehicle V can be leased again. As a result, the user can provide the user with a vehicle V that suits the user's purpose.
