[0007] In the above-mentioned warranty condition setting system, the judgment time remaining life recognition unit may be configured to recognize the judgment time remaining life based on usage history information of the target moving object by the second user when the target moving object has been used by a second user other than the first user prior to the judgment time.

[0012] [1. Configuration of the warranty condition setting system] The configuration of a warranty condition setting system 1 of this embodiment will be described with reference to Figs. 1 to 5. The warranty condition setting system 1 performs processing for setting warranty conditions for a vehicle (corresponding to a mobile object in the present disclosure) traded at a car dealer 100. Transactions include sales of new cars, sales of used cars, vehicle lease contracts, and the like. In this embodiment, a case will be described in which the warranty condition setting system 1 sets warranty conditions for a used target vehicle 60 (corresponding to a target mobile object in the present disclosure).

[0013] 1 illustrates an example in which a first user U1 (a new user of a target vehicle 60) sells a different vehicle 50 that he has been using and switches to the target vehicle 60. The different vehicle 50 and the target vehicle 60 are vehicles of the same manufacturer, traded by a car dealer 100, and their usage status is managed by a vehicle manufacturer server 210, which is the management server of the original vehicle manufacturer.

[0014] The vehicle manufacturer server 210 communicates with the other vehicle 50, the target vehicle 60, and the store management system 101 of the car dealer 100 via the communication network 200. The other vehicle 50 is equipped with sensors 52 that detect a load applied to a target part of the other vehicle 50, and an ECU (Electronic Control Unit) 51, and the ECU 51 transmits load measurement information Lmi indicating the detection result of the load detected by the sensors 52 to the vehicle manufacturer server 210 when the power of the other vehicle 50 is turned on, etc. Similarly, the target vehicle 60 is equipped with an ECU 61 and sensors 62, and the ECU 61 transmits load measurement information Lmi indicating the detection result of the load detected by the sensors 62 to the vehicle manufacturer server 210 when the power of the target vehicle 60 is turned on, etc.

[0015] When another vehicle 50 or a target vehicle 60 is brought into the car dealer 100 for maintenance such as a regular inspection, a service staff member uses a measuring device to measure the physical property values ​​of the target parts of the other vehicle 50 or the target vehicle 60. Then, the store management system 101 transmits physical property measurement information Pmi indicating the measurement results of the physical property values ​​to the vehicle manufacturer server 210.

[0016] In this embodiment, as shown in FIG. 2, the engine, suspension, electrical equipment, and seats are set as target parts for measuring the load and physical property values. For the engine, the shaft torque and rotation speed are measured as load elements, and the elastic modulus (sound speed) of the parts is measured as physical property values. For the suspension, the vibration frequency and acceleration are measured as load elements, and the elastic modulus (sound speed) of the parts is measured as physical property values. For the electrical equipment, the shaft torque and rotation speed of the electric motor, the operating time and output power of the PDU (Power Drive Unit), and the number of charge / discharge cycles and the charge / discharge amount of the battery are measured as load elements. In addition, the runout of the rotating shaft of the electric motor, the cooling performance of the PDU elements, and the charging capacity of the battery are measured as physical property values. For the seat, the number of times of use is measured as a load element, and the spring constant is measured as a physical property value. Load measurement information Lmi and physical property measurement information Pmi for each target part of the other vehicle 50 and the target vehicle 60 are transmitted to the vehicle manufacturer server 210.

[0017] The vehicle manufacturer server 210 receives the load measurement information Lmi transmitted from the other vehicle 50, the load measurement information Lmi transmitted from the target vehicle 60, and the physical property measurement information Pmi transmitted from the store management system 101, and records them for each vehicle in a vehicle management DB (database) 211. Fig. 3 shows the recorded data in the vehicle management DB 211 corresponding to the target vehicle 60 (management number: Cid-001) and the other vehicle 50 (management number: Cid-002).

[0018] For the target vehicle 60, the load measurement information (Lmi-001) and the physical property measurement information (Pmi-001) during the period of use by the first user U1 (user ID: Uid-001) are classified into the load measurement information (Lmi-002) and the physical property measurement information (Pmi-002) during the period of use by the second user U2. For the other vehicle 50, the load measurement information (Lmi-003) and the physical property measurement information (Pmi-003) during the period of use by the first user U1 are recorded.

[0019] The warranty condition setting system 1 is a computer system including a processor 10, a memory 20, a communication unit 30, etc. The warranty condition setting system 1 communicates with a vehicle manufacturer server 210, a terminal device 70 used by a service staff V of a car dealer 100, etc. via a communication network 200 using the communication unit 30. The terminal device 70 is a tablet terminal, a personal computer, a smartphone, etc.

[0020] The memory 20 stores a program 21 for controlling the warranty condition setting system 1, a map (load-fatigue map) 22 for converting the detected load value indicated by the load measurement information Lmi of the target part into a fatigue weight of the target part, and a map (physical property degradation degree-remaining life map) 23 for converting the measured physical property value indicated by the physical property measurement information Pmi of the target part into an estimated remaining life of the target part.

[0021] The processor 10 loads and executes the program 21 to function as a judgment time remaining life recognition unit 11, a remaining life consumption degree prediction unit 12, a remaining life consumption degree correction unit 13, a remaining life decrease prediction period calculation unit 14, and a warranty condition setting unit 15. The processing executed by the judgment time remaining life recognition unit 11 corresponds to the judgment time remaining life recognition step in the warranty condition setting method of the present disclosure, and the processing executed by the remaining life consumption degree prediction unit 12 corresponds to the remaining life consumption degree prediction step in the warranty condition setting method of the present disclosure. The processing executed by the remaining life decrease prediction period calculation unit 14 corresponds to the remaining life decrease prediction period calculation step in the warranty condition setting method of the present disclosure, and the processing executed by the warranty condition setting unit 15 corresponds to the warranty condition setting step of the present disclosure.

[0022] The determination time remaining life recognition unit 11 recognizes the remaining life of the target parts (engine, suspension, electrical equipment, seats) of the target vehicle 60 at the time of sale when the target vehicle 60 is sold to the first user U1 (corresponding to the determination time of this disclosure). The determination time remaining life recognition unit 11 recognizes the remaining life of each target part based on the load measurement information Lmi and physical property measurement information Pmi of each target part during the period of use by the second user U2, who was the previous user of the target vehicle 60, recorded in the vehicle management DB211, for example, by the method described in Japanese Patent Application No. 2022-172125, a previous patent application by the applicant of the present application.

[0023] The determination time remaining life recognition unit 11 applies the load recognized from the load measurement information Lmi of the target part during the period of use by the second user U2 to the load-fatigue level map 22 to obtain the corresponding weight, calculates the cumulative fatigue level by summing the weighted measurement counts for each load level, and calculates a first estimated remaining life by subtracting the cumulative fatigue level from 100%. In addition, the determination time remaining life recognition unit 11 applies the physical property degradation level recognized from the physical property measurement information Pmi to the physical property degradation level-remaining life map 23 to recognize a second estimated remaining life of the target part.

[0024] 4 illustrates a first estimated remaining life A based on the load measurement information Lmi and a second estimated remaining life B based on the physical property measurement information Pmi for a target part of a target vehicle 60, with the vertical axis representing the remaining life rate (the percentage of the remaining life when the life is 100%) and the horizontal axis representing the guaranteed traveling distance of the target vehicle 60 corresponding to the remaining life rate. In FIG. 4, when the traveling distance of the target vehicle 60 reaches Dc2, the second estimated remaining life B is longer than the first estimated remaining life A.

[0025] Therefore, in the period up to Dc2 when the second estimated remaining life B becomes longer than the first estimated remaining life A, the determination time remaining life recognizing unit 11 judges the remaining life of the target part based on the first estimated remaining life A. Also, in the period after Dc when the second estimated remaining life B becomes longer than the first estimated remaining life A, the determination time remaining life recognizing unit 11 recognizes the remaining life of the target part based on the second estimated remaining life B.

[0026] The remaining lifespan prediction unit 12 calculates the remaining lifespan of each target part (engine, suspension, electrical equipment, seat) of the target vehicle 60 after the first user U1 starts using the target vehicle 60 based on the load measurement information Lmi-003 and the physical property measurement information Pmi-003 during the use period of the other vehicle 50 by the first user U1 shown in FIG. 3. The remaining lifespan indicates the length of the remaining lifespan of the target part that is predicted to be consumed (reduced) when the first user U1 uses the other vehicle 50 for one year. The remaining lifespan of each target part is a value obtained by dividing the number of years of reduction in the remaining lifespan of each target part during the period in which the first user U1 used the other vehicle 50 by the number of years in which the first user U1 used the other vehicle 50. The number of years of reduction in the remaining lifespan of each target part is calculated by subtracting the remaining lifespan of each target part at the time when the first user U1 switched from the other vehicle 50 to the target vehicle 60 from the remaining lifespan of each target part at the time when the first user U1 started using the other vehicle 50. The remaining life of each target part is calculated by the same process as that for recognizing the remaining life by the judgment time remaining life recognizing unit 11 described above.

[0027] Here, C1 in Figure 5 shows an example of a prediction of the remaining lifespan of each target part (engine, suspension, electrical system, seats) of the target vehicle 60 during a specified period (2019 to 2020) after the first user U1 starts using the target vehicle 60, expressed as the remaining lifespan (years) to be consumed in one year.

[0028] The remaining lifespan consumption degree correction unit 13 sets the remaining lifespan consumption degree of each target part of the target vehicle 60, which reflects the actual usage status of the target vehicle 60 by the first user U1, as a new remaining lifespan consumption degree based on the load measurement information Lmi-002 and physical property measurement information Pmi-002 for the period after the first user U1 starts using the target vehicle 60 as shown in Figure 3.

[0029] C2 in Fig. 5 illustrates an example of the remaining lifespan of each target part (engine, suspension, electrical equipment, and seats) of the target vehicle 60 corrected by the remaining lifespan degree correction unit 13. In C2, the remaining lifespan of the engine and suspension has decreased, and the remaining lifespan of the seats has increased, compared to the remaining lifespan of each target part in C1 predicted when the first user U1 started using the target vehicle 60. This indicates, for example, that the first user U1 has started using the target vehicle 60 more frequently with a passenger on board, and has become more gentle in his driving.

[0030] The remaining lifespan decrease prediction period calculation unit 14 calculates a remaining lifespan decrease period, which is a prediction period during which the remaining lifespan will decrease to a predetermined judgment value or less after the first user U1 starts using the target vehicle 60, for each target part of the target vehicle 60. The warranty condition setting unit 15 sets warranty conditions for the target vehicle 60 for the first user U1 based on the remaining lifespan decrease prediction period of each target part of the target vehicle 60 calculated by the remaining lifespan decrease prediction period calculation unit 14.

[0031] [2. Setting vehicle warranty conditions] 6, a procedure for setting the warranty conditions of the target vehicle 60 for the first user U1, which is executed by the warranty condition setting system 1, will be described. The warranty condition setting system 1 sets the warranty conditions of the target vehicle 60 when the target vehicle 60 is sold to the first user U1, and changes the warranty conditions of the target vehicle 60 depending on the subsequent usage of the target vehicle 60 by the first user U1.

[0032] 6 for each target part (engine, suspension, electrical equipment, seat) of the target vehicle 60. Steps S1 to S5 and S20 are processes performed by the determination time remaining life recognition unit 11. In step S1, the determination time remaining life recognition unit 11 accesses the vehicle management DB 211 of the vehicle manufacturer server 210, and acquires the load measurement information Lmi and physical property measurement information Pmi of the target part that have been recorded in the vehicle management DB 211 up to the time of sale.

[0033] In the next step S2, the determination time remaining life recognizing unit 11 recognizes a first estimated remaining life corresponding to the accumulated fatigue degree of the target part based on the load measurement information Lmi. In the next step S3, the determination time remaining life recognizing unit 11 recognizes a second estimated remaining life corresponding to the deterioration degree of the physical property value of the target part based on the physical property measurement information Pmi. In the next step S4, the determination time remaining life recognizing unit 11 determines whether the second estimated remaining life is longer than the first estimated remaining life, and if the second estimated remaining life is longer than the first estimated remaining life, proceeds to step S20, and if the second estimated remaining life is equal to or shorter than the first estimated remaining life, proceeds to step S5.

[0034] In step S5, the judgment time remaining life recognition unit 11 sets the first estimated remaining life to the sales time remaining life of the target part. In step S20, the judgment time remaining life recognition unit 11 sets the second estimated remaining life to the sales time remaining life of the target part. The following steps S6 to S7 are processed by the remaining lifespan utilization degree prediction unit 12. In step S6, the remaining lifespan utilization degree prediction unit 12 accesses the vehicle management DB 211 of the vehicle manufacturer server 210, and acquires load measurement information Lmi and physical property measurement information Pmi (Lmi-003, Pmi-003 in Figure 3) of the target part of the other vehicle 50 recorded when the first user U1 was using the other vehicle 50, which is usage history information of the other vehicle 50 by the first user U1.

[0035] In the next step S7, the remaining lifespan utilization rate prediction unit 12 predicts the remaining lifespan utilization rate of the target part when the first user U1 uses the target vehicle based on the usage history information of the other vehicle 50 by the first user U1 (see C1 in FIG. 5). The following step S8 is a process performed by the remaining lifespan reduction prediction period calculation unit 14.

[0036] Here, the calculation process of the remaining life decrease predicted period by the remaining life decrease predicted period calculation unit 14 will be described with reference to Fig. 8. Fig. 8 shows a case where the warranty conditions are set and reviewed for one target part of the target vehicle 60. Fig. 8 shows the progress of the decrease in the remaining life of the target part according to the mileage (accumulated mileage) of the target vehicle 60, with the vertical axis set to the remaining life (remaining life rate) of the target part and the horizontal axis set to the mileage of the target vehicle. t1 in Fig. 8 is the time when the target vehicle 60 is sold to the first user U1.

[0037] 8 (0) shows the progress of the decrease in the remaining lifespan of the target part obtained by multiplying the measured remaining lifespan of the target part obtained from durability tests carried out by the vehicle manufacturer for the model of the target vehicle 60 by a weighting coefficient, and (1) shows the progress of the decrease in the remaining lifespan until the remaining lifespan at the time of sale recognized by the judgment time remaining lifespan recognition unit 11. (2) shows the progress of the decrease in the remaining lifespan of the target part when the remaining lifespan consumption degree of the target part predicted by the remaining lifespan consumption degree prediction unit 12 when the first user U1 uses the target vehicle 60 is applied.

[0038] (3) is the trend of the decrease in the remaining lifespan of the target part, which is (2) multiplied by a burden coefficient to provide some leeway in the warranty conditions, and the remaining lifespan of the target part becomes zero at the point in time t2 (the point in time when the mileage of the target vehicle 60 becomes b). Therefore, the remaining lifespan decrease prediction period calculation unit 14 calculates the period from t1 to t2 as the remaining lifespan decrease prediction period.

[0039] The subsequent steps S10 to S11 are processes performed by the warranty condition setting unit 15. The warranty condition setting unit 15 sets the shortest remaining life reduction prediction period and the predicted distance corresponding to this prediction period among the remaining life reduction prediction periods of each target part (engine, suspension, electrical equipment, seat) calculated by the processes of steps S1 to S8 and step S20 as the warranty conditions (warranty period, guaranteed distance) of the target vehicle 60 at the time of sale. Note that if the remaining life reduction prediction period is shorter than the period until d when the remaining life of the target part becomes zero in the transition (0) of the reduction in remaining life due to the durability test shown in FIG. 8, the warranty condition setting unit 15 sets the period from t1 to d and the distance corresponding to this period as the warranty conditions (warranty period, guaranteed distance) of the target vehicle 60 at the time of sale.

[0040] In the next step S11, the warranty condition setting unit 15 transmits warranty condition information indicating the warranty conditions of the target vehicle to the terminal device 70 of the service staff V. The service staff V shows the warranty conditions of the target vehicle 60 displayed on the terminal device 70 to the first user U1 and explains the warranty conditions, etc.

[0041] [3. Changing vehicle warranty conditions] According to the flowchart shown in FIG. 7, the process steps executed by the warranty condition setting system 1 to reset the warranty conditions of the target vehicle 60 in accordance with the usage status of the target vehicle 60 by the first user U1 after the first user U1 starts using the target vehicle 60 will be described.

[0042] Steps S50 to S53 in Fig. 7 are processes performed by the remaining lifespan utilization degree correction unit 13. In step S30, the remaining lifespan utilization degree correction unit 13 accesses the vehicle management DB 211 of the vehicle manufacturer server 210 to acquire mileage information of the target vehicle 60. In the following step S51, the remaining lifespan utilization degree correction unit 13 determines whether the mileage of the target vehicle 60 has become equal to or greater than the guaranteed distance at the time of sale -α (margin value). Then, when the mileage of the target vehicle 60 has become equal to or greater than the guaranteed distance at the time of sale -α, the remaining lifespan utilization degree correction unit 13 advances the process to step S52, and when the mileage of the target vehicle 60 is less than the guaranteed distance at the time of sale -α, the remaining lifespan utilization degree correction unit 13 advances the process to step S50.

[0043] In step S52, the remaining lifespan utilization correction unit 13 accesses the vehicle management DB 211 of the vehicle manufacturer server 210 and acquires load measurement information Lmi and physical property measurement information Pmi (Lmi-001, Pmi-001 in Figure 3) of each target part of the target vehicle 60 recorded after the first user U1 started using the target vehicle 60, which is usage history information of the target vehicle 60 by the first user U1.

[0044] In the next step S53, the remaining lifespan consumption degree correction unit 13 corrects the consumption degree of each target part of the target vehicle 60 based on the usage history information of the target vehicle 60 by the first user U1 (see C2 in FIG. 5). The next step S54 is processing by the remaining lifespan reduction prediction period calculation unit 14. In step S54, the remaining lifespan reduction prediction period calculation unit 14 recalculates the remaining lifespan reduction prediction period for each target part based on the corrected remaining lifespan consumption degree of each target part.

[0045] The subsequent steps S55 to S65 and S60 are processes performed by the warranty condition setting unit 15. In step S55, the warranty condition setting unit 15 sets the shortest remaining life decrease prediction period of the remaining life decrease prediction periods of each target part recalculated in step S54 as a comparison prediction period. In the next step S56, the warranty condition setting unit 15 determines whether the comparison prediction period is longer than the warranty period of the target vehicle 60 at the time of sale.

[0046] Then, when the comparison target prediction period is longer than the warranty period of the target vehicle 60 at the time of sale, the warranty condition setting unit 15 proceeds to step S60 to extend the warranty period of the target vehicle 60 and proceeds to step S57. On the other hand, when the comparison target prediction period is less than or equal to the warranty period of the target vehicle 60 at the time of sale, the warranty condition setting unit 15 proceeds to step S57, and in this case, the warranty period of the target vehicle 60 is not changed.

[0047] Here, (5) in FIG. 8 is the transition of the decrease in the remaining life of the target part recalculated by the remaining life decrease prediction period calculation unit 14 based on the remaining life consumption rate of the target part corrected by the remaining life consumption rate correction unit 13 at or immediately before time t2. Further, (6) in FIG. 8 is the transition of the decrease in the remaining life of the target part multiplied by the weighting coefficient for giving a margin to the warranty conditions in (5), and at time t3 (when the mileage of the target vehicle 60 reaches c), the remaining life of the target part becomes zero. Therefore, the warranty condition setting unit 15 extends the warranty distance of the target part by the period from b - a in (7) at the time of sale to c - b in (8).

[0048] [4. Other Embodiments] In the above embodiment, by the process according to the flowchart shown in FIG. 7, when the mileage of the target vehicle 60 approaches the warranty distance at the time of sale, the remaining life consumption rate of the target part is corrected based on the usage history information during the entire usage period of the target vehicle 60 by the first user U1, and the warranty conditions of the target vehicle 60 are changed. As another embodiment, as shown in FIG. 9, the degree of decrease in the remaining life may be corrected based on the usage history information during a predetermined period immediately before, instead of during the entire usage period of the target vehicle 60 by the first user U1.

[0049] Similar to FIG. 8, FIG. 9 shows the transition of the decrease in the remaining life of the target part according to the mileage of the target vehicle 60, with the vertical axis set to the remaining life (remaining life rate) of the target part and the horizontal axis set to the mileage of the target vehicle. The same elements as in FIG. 8 are denoted by the same reference numerals. t11 in FIG. 9 is the time when the mileage of the target vehicle 60 reaches a' (a < a' < b).

[0050] (4)' in FIG. 9 is the actual remaining lifespan of the target part from t11 to t2. The remaining lifespan utilization degree correction unit 13 corrects the remaining lifespan deterioration degree of the target part based on (4)'. (2)' is the progress of the decrease in the remaining lifespan of the target part calculated based on the remaining lifespan deterioration degree corrected based on (4)'. (3)' is the progress of the decrease in the remaining lifespan of the target part calculated by multiplying (2)' by a weighting coefficient to allow some leeway in the warranty conditions, and the remaining lifespan of the target part becomes zero at the point in time t21 (the point in time when the mileage of the target vehicle 60 becomes b').

[0051] In this way, by correcting the degree of remaining life deterioration of the target parts based on the actual degree of remaining life utilization in a specified period immediately prior, rather than the entire period of use of the target vehicle 60 by the first user U1, the warranty conditions of the target vehicle 60 can be changed to better reflect changes in the usage conditions of the first user U1 while the first user U1 is using the target vehicle 60.

[0052] In the above embodiment, the engine, suspension, electrical equipment, and seats are given as examples of target parts for predicting the degree of remaining lifespan. However, other parts whose degree of reduction in remaining lifespan changes depending on the vehicle usage conditions, such as the battery, may also be used as target parts.

[0053] In the above embodiment, a vehicle is shown as the moving body of the present disclosure, but the moving body of the present disclosure may be an aircraft, a ship, or the like.

[0054] In the above embodiment, a remaining lifespan consumption degree correction unit 13 was provided to correct the remaining lifespan consumption degree of each target part of the target vehicle 60 based on the usage history of the target vehicle 60 by the first user U1, but the configuration may also omit the remaining lifespan consumption degree correction unit 13.

[0055] In the above embodiment, the remaining lifespan utilization rate was predicted and the remaining lifespan reduction prediction period was calculated for four target parts (engine, suspension, electrical equipment, and seats) of the target vehicle 60, but the remaining lifespan utilization rate may also be predicted and the remaining lifespan reduction prediction period calculated for three or less or five or more target parts.

[0056] In the above embodiment, a used target vehicle 60 is shown, but the target vehicle 60 may be a new vehicle.

[0059] [5. Configuration supported by the above embodiment] The above embodiment is a specific example of the following configuration.

[0060] (Configuration 1) A warranty condition setting system comprising: a judgment time remaining lifespan recognition unit that recognizes the judgment time remaining lifespan, which is the remaining lifespan of a target moving object at the judgment time; a remaining lifespan consumption degree prediction unit that predicts the remaining lifespan consumption degree, which is the degree of consumption of the remaining lifespan of the target moving object per specified period when a first user uses the target moving object, based on usage history information of other moving objects other than the target moving object by a first user who will start using the target moving object after the judgment time; a remaining lifespan consumption prediction period calculation unit that calculates a remaining lifespan reduction prediction period, which is a predicted period during which the remaining lifespan of the target moving object will reduce from the judgment time remaining lifespan to a specified judgment value or less, assuming that the first user will use the target moving object after the judgment time, based on the remaining lifespan consumption degree; and a warranty condition setting unit that sets warranty conditions for the target moving object based on the remaining lifespan reduction prediction period. According to the warranty condition setting system of configuration 1, the warranty conditions of a moving object such as a vehicle can be appropriately set according to the usage status of the moving object by the user.

[0061] (Configuration 2) A warranty condition setting system as described in Configuration 1, comprising a remaining lifespan consumption degree correction unit that corrects the remaining lifespan consumption degree based on the usage status of the target moving object by the first user, wherein the remaining lifespan decrease prediction period calculation unit recalculates the remaining lifespan decrease prediction period based on the corrected remaining lifespan consumption degree, and the warranty condition setting unit resets the warranty conditions based on the remaining lifespan decrease prediction period calculated by the remaining lifespan decrease prediction period calculation unit based on the corrected remaining lifespan consumption degree. According to the warranty condition setting system of configuration 2, the degree of remaining lifespan consumption can be corrected in accordance with the usage status after the user actually starts using the mobile object, thereby making it possible to set the warranty conditions of the mobile object more appropriately.

[0062] (Configuration 3) A guarantee condition setting system as described in Configuration 1 or Configuration 2, wherein the determination time remaining life recognition unit recognizes the determination time remaining life based on usage history information of the target moving object by a second user other than the first user if the target moving object was used by the second user before the determination time. According to the guarantee condition setting system of configuration 3, the remaining life span at the time of determination can be appropriately recognized according to the usage record of the target moving object by the past users.

[0063] (Configuration 4) A warranty condition setting system as described in Configuration 1 or Configuration 2, wherein the judgment time remaining life recognition unit recognizes the judgment time remaining life for each of multiple target parts provided on the target moving body, the remaining life consumption prediction unit predicts the remaining life consumption degree for each of the multiple target parts, the remaining life reduction prediction period calculation unit calculates the remaining life reduction prediction period for each of the multiple target parts, and the warranty condition setting unit sets the warranty conditions of the target moving body based on the remaining life reduction prediction periods of the multiple target parts. According to the warranty condition setting system of configuration 4, the degree of decrease in the remaining lifespan of each target part differs depending on the usage of the target moving object, so that warranty conditions can be set according to the usage of the target moving object by the first user based on the predicted period of decrease in the remaining lifespan of multiple target parts.

[0064] (Configuration 5) A warranty condition setting method executed by a computer, the warranty condition setting method including: a judgment time remaining life calculation step for calculating a judgment time remaining life, which is the remaining life of a moving body at a judgment time, based on specified remaining life calculation conditions; a remaining life consumption degree prediction step for predicting the consumption degree of the remaining life of the moving body per specified period when a user uses the moving body based on driving history information of the user who will start using the moving body after the judgment time; a remaining life consumption transition prediction step for predicting the consumption degree of the remaining life of the moving body when it is assumed that the user will use the moving body after the judgment time, based on the consumption degree; and a warranty condition setting step for setting, as a warranty condition of the moving body at the judgment time, a period until a specific time point at which the difference between the remaining life of the moving body predicted by the remaining life consumption transition prediction step and the judgment time remaining life is equal to or less than a specified value, or an estimated moving distance of the moving body from the judgment time at the specific time point. By executing the warranty condition setting method of configuration 3 by a computer, it is possible to obtain the same effects as the warranty condition setting system of configuration 1.
