DETAILED DESCRIPTION

[0028] [1. Structure of warranty condition setting system]

[0029] Reference Figure 1 to Figure 5 , the structure of the warranty condition setting system 1 of this embodiment is described. The warranty condition setting system 1 performs the following processing: setting the warranty conditions of the vehicle (equivalent to the mobile body of the present disclosure) traded by the automobile dealer 100. The transaction includes the sale of a new car, the sale of a used car, a vehicle lease contract, etc. In this embodiment, the warranty condition setting system 1 sets the warranty conditions of the used target vehicle 60 (equivalent to the target mobile body of the present disclosure).

[0030] Figure 1 The example shows a case where the first user U1 (new user of the target vehicle 60) sells the other vehicle 50 used so far and replaces it with the target vehicle 60. The other vehicle 50 and the target vehicle 60 are vehicles of the same manufacturer, and are traded through the car dealer 100. The usage status is managed by the vehicle manufacturer server 210, which is the management server of the vehicle manufacturer as the manufacturer.

[0031] The vehicle manufacturer server 210 communicates with the other vehicle 50, the target vehicle 60, and the store management system 101 of the automobile dealer 100 via the communication network 200. The other vehicle 50 is provided with a sensor 52 for detecting a load applied to a target component of the other vehicle 50 and an ECU (Electronic Control Unit) 51, and the ECU 51 transmits load measurement information Lmi indicating a detection result of the load detected by the sensor 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 provided with an ECU 61 and a sensor 62, and the ECU 61 transmits load measurement information Lmi indicating a detection result of the load detected by the sensor 62 to the vehicle manufacturer server 210 when the power of the target vehicle 60 is turned on, etc.

[0032] When the automobile dealer 100 brings another vehicle 50 or a target vehicle 60 for maintenance such as regular inspection, the service personnel use 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 value measurement information Pmi indicating the measurement results of the physical property values ​​to the vehicle manufacturer server 210.

[0033] In this embodiment, as the object component to be measured for load and physical property values, Figure 2 As shown, an engine, chassis, electronic equipment and seats are set. Regarding the engine, the shaft torque and rotation speed are measured as elements of the load, and the elastic modulus (speed of sound) of the component is measured as a physical property value. Regarding the chassis, the vibration frequency and acceleration are measured as elements of the load, and the elastic modulus (speed of sound) of the component is measured as a physical property value. Regarding the electronic equipment, the shaft torque and rotation speed of the motor, the working time and output power of the PDU (Power Drive Unit), and the number of charge and discharge times and the charge and discharge amount of the battery are measured as elements of the load. In addition, the shaking of the rotating shaft of the motor, the cooling performance of the components of the PDU, and the charging capacity of the battery are measured as physical property values. Regarding the seat, the number of uses is measured as an element of the load, and the spring constant is measured as a physical property value. The load measurement information Lmi and the physical property value measurement information Pmi related to each object component of the other vehicle 50 and the object vehicle 60 are sent to the vehicle manufacturer server 210.

[0034] The vehicle manufacturer server 210 receives the load measurement information Lmi sent from other vehicles 50 , the load measurement information Lmi sent from the target vehicle 60 , and the physical property value measurement information Pmi sent from the store management system 101 , and records them in a vehicle management DB (database) 211 for each vehicle. Figure 3The recorded data of the vehicle management DB 211 corresponding to the target vehicle 60 (management No.: Cid-001) and the other vehicle 50 (management No.: Cid-002) are shown.

[0035] For the target vehicle 60, the load measurement information (Lmi-001) and the physical property value measurement information (Pmi-001) during the use period of the first user U1 (user ID: Uid-001) and the load measurement information (Lmi-002) and the physical property value measurement information (Pmi-002) during the use period of the second user U2 are divided. For the other vehicles 50, the load measurement information (Lmi-003) and the physical property value measurement information (Pmi-003) during the use period of the first user U1 are recorded.

[0036] 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 person V of the automobile dealer 100, etc. through the communication unit 30 via a communication network 200. The terminal device 70 is a tablet terminal, a personal computer, a smart phone, etc.

[0037] The memory 20 stores a control program 21 for the warranty condition setting system 1, a mapping (load-fatigue mapping) 22 for converting the detected value of the load indicated by the load measurement information Lmi of the object component into a weight of the fatigue degree of the object component, and a mapping (physical property value degradation degree-remaining life mapping) 23 for converting the measured value of the physical property value indicated by the physical property value measurement information Pmi of the object component into an estimated remaining life of the object component.

[0038] The processor 10 functions as a judgment moment remaining life recognition unit 11, a remaining life consumption degree prediction unit 12, a remaining life consumption degree correction unit 13, a remaining life reduction prediction period calculation unit 14, and a warranty condition setting unit 15 by reading and executing the program 21. The processing performed by the judgment moment remaining life recognition unit 11 is equivalent to the judgment moment remaining life recognition step in the warranty condition setting method of the present disclosure, and the processing performed by the remaining life consumption degree prediction unit 12 is equivalent to the remaining life consumption degree prediction step in the warranty condition setting method of the present disclosure. The processing performed by the remaining life reduction prediction period calculation unit 14 is equivalent to the remaining life reduction prediction period calculation step in the warranty condition setting method of the present disclosure, and the processing performed by the warranty condition setting unit 15 is equivalent to the warranty condition setting step of the present disclosure.

[0039] The determination time remaining life recognition unit 11 recognizes the remaining life of the target components (engine, chassis, electronic equipment, seat) 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 the present disclosure). The determination time remaining life recognition unit 11 recognizes the remaining life of each target component based on the load measurement information Lmi and physical property value measurement information Pmi of each target component during the use period of the target vehicle 60 by the second user U2, which is the user up to that time, recorded in the vehicle management DB 211, for example, by the method described in the prior patent application of the applicant of the present application, namely Japanese Patent Application No. 2022-172125.

[0040] The judgment time remaining life recognition unit 11 applies the load recognized from the load measurement information Lmi of the target component during the use period of the second user U2 to the load-fatigue degree map 22, obtains the corresponding weight, calculates the cumulative fatigue degree by summing up the weighted measurement times for each load level, and calculates the first estimated remaining life by subtracting the cumulative fatigue degree from 100%. In addition, the judgment time remaining life recognition unit 11 applies the physical property value degradation degree recognized from the physical property value measurement information Pmi to the physical property value degradation degree-remaining life map 23 to recognize the second estimated remaining life of the target component.

[0041] exist Figure 4 In the figure, for the target parts of the target vehicle 60, the vertical axis is set to the remaining life rate (the ratio of the remaining life when the life is set to 100%), and the horizontal axis is set to the travel warranty distance of the target vehicle 60 corresponding to the remaining life rate, and the first estimated remaining life A based on the load measurement information Lmi and the second estimated remaining life B based on the physical property value measurement information Pmi are illustrated. Figure 4 In FIG. 5 , when the travel distance of the target vehicle 60 is Dc2 , the second estimated remaining life B is longer than the first estimated remaining life A. In FIG.

[0042] Therefore, the determination time remaining life recognition unit 11 determines the remaining life of the target component based on the first estimated remaining life A until Dc2 when the second estimated remaining life B is longer than the first estimated remaining life A. Furthermore, the determination time remaining life recognition unit 11 recognizes the remaining life of the target component based on the second estimated remaining life B during the period after Dc2 when the second estimated remaining life B is longer than the first estimated remaining life A.

[0043] The remaining life consumption degree prediction unit 12 is based on Figure 3The first user U1 shown uses the load measurement information Lmi-003 and the physical property value measurement information Pmi-003 during the use period of the other vehicle 50 to calculate the remaining life consumption degree of each target component (engine, chassis, electronic equipment, seat) of the target vehicle 60 after the first user U1 starts to use the target vehicle 60. The remaining life consumption degree indicates the length of the remaining life of the target component that is predicted to be consumed (reduced) when the first user U1 uses the other vehicle 50 for 1 year. The remaining life consumption degree of each target component is the value obtained by dividing the number of years of reduction in the remaining life of each target component during the period when the first user U1 uses the other vehicle 50 by the number of years the first user U1 uses the other vehicle 50. The number of years of reduction in the remaining life of each target component is calculated by subtracting the remaining life of each target component at the time when the first user U1 changes from the other vehicle 50 to the target vehicle 60 from the remaining life of each target component at the time when the first user U1 starts to use the other vehicle 50. The remaining life of each target component is calculated by the same processing as the above-mentioned determination time remaining life recognition unit 11 recognizes the remaining life.

[0044] Here, Figure 5 C1 shows the following example: predicting the remaining life consumption degree of each target component (engine, chassis, electronic equipment, seat) of the target vehicle 60 within a specified period (2019-2020) after the first user U1 starts using the target vehicle 60 according to the remaining life consumed in 1 year (years).

[0045] The remaining life consumption degree correction unit 13 is based on Figure 3 The load measurement information Lmi-002 and the physical property value measurement information Pmi-002 shown in the period after the first user U1 starts using the target vehicle 60 will set the remaining life consumption degree of each target component of the target vehicle 60 reflecting the usage status of the target vehicle 60 by the first user U1 as a new remaining life consumption degree.

[0046] Figure 5 C2 shows the remaining life consumption of each object component (engine, chassis, electronic equipment, seat) of the target vehicle 60 corrected by the remaining life consumption correction unit 13. In C2, compared with the remaining life consumption of each object component of C1 predicted when the first user U1 starts to use the target vehicle 60, the remaining life consumption of the engine and chassis is reduced, and the remaining life consumption of the seat is increased. This means that, for example, the first user U1 uses the target vehicle 60 more often with a fellow passenger, and the driving becomes stable.

[0047] The remaining life reduction prediction period calculation unit 14 calculates a remaining life reduction period, which is a prediction period during which the remaining life of each target component of the target vehicle 60 is reduced to or less than a predetermined determination value from the time when the first user U1 starts using the target vehicle 60. The warranty condition setting unit 15 sets a warranty condition for the target vehicle 60 of the first user U1 based on the remaining life reduction prediction period of each target component of the target vehicle 60 calculated by the remaining life reduction prediction period calculation unit 14.

[0048] [2. Setting of vehicle warranty conditions]

[0049] according to Figure 6 The flowchart shown in the figure explains the steps of setting the warranty conditions of the target vehicle 60 for the first user U1, which are executed by the warranty condition setting system 1. 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 according to the usage status of the target vehicle 60 by the first user U1 thereafter.

[0050] The warranty condition setting system 1 executes a warranty condition setting for each target component (engine, chassis, electronic equipment, seat) of the target vehicle 60. Figure 6 Steps S1 to S8 and S20 are the processing 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 to obtain the load measurement information Lmi and the physical property value measurement information Pmi of the target part recorded in the vehicle management DB 211 until the time of sale.

[0051] In the next step S2, the determination time remaining life recognition unit 11 recognizes the first estimated remaining life corresponding to the accumulated fatigue degree of the target component based on the load measurement information Lmi. In the next step S3, the determination time remaining life recognition unit 11 recognizes the second estimated remaining life corresponding to the degradation degree of the physical property value of the target component based on the physical property value measurement information Pmi. In the next step S4, the determination time remaining life recognition unit 11 determines whether the second estimated remaining life is longer than the first estimated remaining life. If the second estimated remaining life is longer than the first estimated remaining life, the process proceeds to step S20. If the second estimated remaining life is less than the first estimated remaining life, the process proceeds to step S5.

[0052] In step S5, the judgment time remaining life recognition unit 11 sets the first estimated remaining life as the remaining life of the object component at the time of sale. In step S20, the judgment time remaining life recognition unit 11 sets the second estimated remaining life as the remaining life of the object component at the time of sale. The following steps S6 to S7 are processed by the remaining life consumption degree prediction unit 12. In step S6, the remaining life consumption degree prediction unit 12 accesses the vehicle management DB 211 of the vehicle manufacturer server 210, obtains the load measurement information Lmi and physical property value measurement information Pmi (of the object component of the other vehicle 50, which is the usage history information of the first user U1 on the other vehicle 50, recorded when the first user U1 uses the other vehicle 50) Figure 3 Lmi-003, Pmi-003).

[0053] In the next step S7, the remaining life consumption rate prediction unit 12 predicts the remaining life consumption rate of the target component 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 (refer to Figure 5 The next step S8 is a process performed by the remaining life reduction prediction period calculation unit 14.

[0054] Here, refer to Figure 8 , the calculation process of the remaining life reduction prediction period performed by the remaining life reduction prediction period calculation unit 14 is described. Figure 8 The following illustrates a case where warranty conditions are set and re-evaluated for one target component of the target vehicle 60 . Figure 8 The vertical axis is set to the remaining life (remaining life rate) of the target component, and the horizontal axis is set to the travel distance of the target vehicle, and the transition of the reduction of the remaining life of the target component corresponding to the travel distance (cumulative travel distance) of the target vehicle 60 is shown. Figure 8 t1 is the time when the target vehicle 60 is sold to the first user U1.

[0055] Figure 8 (0) is a transition of the reduction in the remaining life obtained by multiplying the measured value of the remaining life of the target component obtained from the durability test conducted by the vehicle manufacturer on the model of the target vehicle 60 by a weighting coefficient, and (1) is a transition of the reduction in the remaining life until the remaining life at the time of sale recognized by the determination time remaining life recognition unit 11. (2) is a transition of the reduction in the remaining life of the target component when the remaining life consumption degree of the target component when the first user U1 uses the target vehicle 60 is applied, which is predicted by the remaining life consumption degree prediction unit 12.

[0056] (3) is the transition of the reduction of the remaining life of the target component obtained by multiplying (2) by a weighting coefficient for providing a margin for the warranty condition. At time t2 (time when the travel distance of the target vehicle 60 reaches b), the remaining life of the target component becomes zero. Therefore, the remaining life reduction prediction period calculation unit 14 calculates the period from t1 to t2 as the remaining life reduction prediction period.

[0057] The next steps S10 to S11 are processed 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 the prediction period among the remaining life reduction prediction periods of each target component (engine, chassis, electronic equipment, seat) calculated by the processing of steps S1 to S8 and step S20 as the warranty condition (warranty period, warranty distance) of the target vehicle 60 when it is sold. It should be noted that the warranty condition (warranty period, warranty distance) is set when the remaining life reduction prediction period is shorter than that of the target component (engine, chassis, electronic equipment, seat). Figure 8 In the case where the period from t1 to d when the remaining life of the target component becomes zero in the transition (0) of the decrease in the remaining life based on the durability test shown is short, the warranty condition setting unit 15 sets the period from t1 to d and the distance corresponding to the period as the warranty conditions (warranty period, warranty distance) of the target vehicle 60 when it is sold.

[0058] 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 personnel V. The service personnel 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.

[0059] [3. Changes to vehicle warranty conditions]

[0060] according to Figure 7 The flowchart shown describes the steps of a process executed by the warranty condition setting system 1 to reset the warranty conditions of the target vehicle 60 according to the usage status of the target vehicle 60 by the first user U1 after the first user U1 starts using the target vehicle 60 .

[0061] Figure 7Steps S50 to S53 are processes performed by the remaining life consumption degree correction unit 13. In step S50, the remaining life consumption degree correction unit 13 accesses the vehicle management DB 211 of the vehicle manufacturer server 210 to obtain the driving distance information of the target vehicle 60. In the next step S51, the remaining life consumption degree correction unit 13 determines whether the driving distance of the target vehicle 60 is greater than the warranty distance - α (remaining value) at the time of sale. Then, the remaining life consumption degree correction unit 13 causes the process to enter step S52 when the driving distance of the target vehicle 60 is greater than the warranty distance - α at the time of sale, and causes the process to enter step S50 when the driving distance of the target vehicle 60 is less than the warranty distance - α at the time of sale.

[0062] In step S52, the remaining life consumption degree correction unit 13 accesses the vehicle management DB 211 of the vehicle manufacturer server 210, and obtains the load measurement information Lmi and the physical property value measurement information Pmi of each object component of the object vehicle 60 recorded after the first user U1 starts using the object vehicle 60 as the usage history information of the first user U1 using the object vehicle 60 ( Figure 3 Lmi-001, Pmi-001).

[0063] In the next step S53, the remaining life consumption degree correction unit 13 corrects the remaining life consumption degree of each target component of the target vehicle 60 based on the usage history information of the target vehicle 60 used by the first user U1 (see Figure 5 The next step S54 is a process performed by the remaining life reduction prediction period calculation unit 14. In step S54, the remaining life reduction prediction period calculation unit 14 recalculates the remaining life reduction prediction period for each target component based on the corrected remaining life consumption degree of each target component.

[0064] The following steps S55 to S65 and S60 are processes executed by the warranty condition setting unit 15. In step S55, the warranty condition setting unit 15 uses the shortest remaining life reduction prediction period among the remaining life reduction prediction periods of each target component recalculated in step S54 as the comparison target prediction period. In the following step S56, the warranty condition setting unit 15 determines whether the comparison target prediction period is longer than the warranty period of the target vehicle 60 at the time of sale.

[0065] 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 advances the process to step S60, extends the warranty period of the target vehicle 60, and advances the process to step S57. On the other hand, when the comparison target prediction period is less than the warranty period of the target vehicle 60 at the time of sale, the warranty condition setting unit 15 advances the process to step S57, and in this case, the warranty period of the target vehicle 60 is not changed.

[0066] Here, Figure 8 (5) is the decrease in the remaining life of the target component calculated again by the remaining life reduction prediction period calculation unit 14 based on the remaining life consumption degree of the target component corrected by the remaining life consumption degree correction unit 13 at time t2 or immediately before t2. Figure 8 (6) is the decrease in the remaining life of the target component obtained by multiplying (5) by a weighting coefficient for providing a margin for the warranty condition. At time t3 (when the travel distance of the target vehicle 60 reaches c), the remaining life of the target component becomes zero. Therefore, the warranty condition setting unit 15 extends the warranty distance of the target component from ba at the time of sale (7) by the period of cb (8).

[0067] [4. Other embodiments]

[0068] In the above embodiment, by Figure 7 According to the process of the flowchart shown in FIG. 1 , when the driving distance of the target vehicle 60 becomes close to the warranty distance at the time of sale, the remaining life consumption degree of the target component is corrected based on the usage history information of the first user U1 during the entire use period of the target vehicle 60, and the warranty condition of the target vehicle 60 is changed. As another embodiment, Fig. 9 As shown, the remaining life consumption degree may be corrected based on usage history information in a previous predetermined period instead of usage history information in the entire usage period of the target vehicle 60 used by the first user U1 .

[0069] Fig. 9 and Figure 8 Similarly, the vertical axis is set to the remaining life (remaining life rate) of the target component, and the horizontal axis is set to the travel distance of the target vehicle, and the decrease in the remaining life of the target component corresponding to the travel distance of the target vehicle 60 is shown. Figure 8 The same elements are provided with the same reference numerals. Fig. 9 t11 is the time when the travel distance of the target vehicle 60 reaches a′ (a<a′<b).

[0070] Fig. 9(4)' is the actual situation of the remaining life consumption degree of the object component between t11 and t2. The remaining life consumption degree correction unit 13 corrects the remaining life consumption degree of the object component based on (4)'. (2)' is the transition of the reduction of the remaining life of the object component calculated based on the remaining life consumption degree after correction of (4)'. (3)' is the transition of the reduction of the remaining life of the object component obtained by multiplying (2)' by a weighting coefficient used to allow room for warranty conditions. At the time t21 (the time when the travel distance of the object vehicle 60 becomes b'), the remaining life of the object component becomes zero.

[0071] In this way, the remaining life consumption degree of the target component is corrected based not on the entire usage period of the target vehicle 60 by the first user U1, but on the actual situation of the remaining life consumption degree in the immediately preceding specified period. This can further reflect the change in the usage status of the first user U1 during the use of the target vehicle 60 by the first user U1 to change the warranty conditions of the target vehicle 60.

[0072] In the above embodiment, the engine, chassis, electronic equipment, and seat are exemplified as target components for predicting the degree of remaining life consumption, but other components such as batteries whose degree of reduction in remaining life varies depending on the use of the vehicle may also be used as target components.

[0073] In the above-mentioned embodiment, a vehicle is shown as the movable body of the present disclosure, but the movable body of the present disclosure may be an airplane, a ship, or the like.

[0074] In the above embodiment, the remaining life consumption degree correction unit 13 is provided to correct the remaining life consumption degree of each target component of the target vehicle 60 based on the actual usage of the target vehicle 60 by the first user U1. However, a configuration in which the remaining life consumption degree correction unit 13 is omitted may be adopted.

[0075] In the above embodiment, the remaining life consumption degree is predicted for the four target components (engine, chassis, electronic equipment, and seat) of the target vehicle 60 and the remaining life reduction prediction period is calculated, but the remaining life consumption degree can also be predicted for less than three or more than five target components and the remaining life reduction prediction period can be calculated.

[0076] In the above embodiment, a used target vehicle 60 is shown, but the target vehicle 60 may be a new vehicle. When the target vehicle 60 is a new vehicle, the determination time remaining life recognition unit 11 recognizes the standard remaining life of each target component corresponding to the model or model of the target vehicle 60 as the remaining life of each target component of the target vehicle 60 at the time of sale.

[0077] In the above embodiment, the warranty condition setting system 1 that communicates with the vehicle manufacturer server 210 and the terminal device 70 is shown, but the structure of the warranty condition setting system 1 may be partially or entirely constituted by the store management system 101, the vehicle manufacturer server 210, and the terminal device 70. When the warranty condition setting system 1 is constituted as a part of the function of the vehicle manufacturer server 210, the warranty condition information WTi is sent from the vehicle manufacturer server 210 to the terminal device 70. When the warranty condition setting system 1 is constituted as a part of the function of the store management system 101, the load measurement information Lmi is sent from the vehicle manufacturer server 210 to the store management system 101, and the warranty condition information WTi is sent from the store management system 101 to the terminal device 70.

[0078] also, Figure 1 This is a schematic diagram that distinguishes the structure of the warranty condition setting system 1 according to the main processing content in order to facilitate understanding of the present invention. The warranty condition setting system 1 can also be configured by other distinction methods. In addition, the processing of each structural element can be performed by one hardware unit or by multiple hardware units. In addition, Figure 6 , Figure 7 The processing of each component shown may be executed by one program or by a plurality of programs.

[0079] [5. Structure supported by the above-mentioned embodiment]

[0080] The above-mentioned embodiment is a specific example of the following structure.

[0081] (Structure 1) A warranty condition setting system comprising:

[0082] A judgment-time remaining life identification unit, which identifies the remaining life of the object mobile body at the judgment time, i.e., the judgment-time remaining life; a remaining life consumption degree prediction unit, which predicts the degree of consumption of the remaining life of the object mobile body for each specified period when the first user uses the object mobile body, i.e., the remaining life consumption degree, based on the usage history information of other mobile bodies other than the object mobile body used by the first user who starts using the object mobile body after the judgment time; a remaining life reduction prediction period calculation unit, which calculates the prediction period during which the remaining life of the object mobile body is reduced from the remaining life at the judgment time to below a specified judgment value based on the remaining life consumption degree, i.e., the remaining life reduction prediction period, assuming that the first user uses the object mobile body after the judgment time; and a warranty condition setting unit, which sets the warranty condition of the object mobile body based on the remaining life reduction prediction period.

[0083] According to the warranty condition setting system of configuration 1, it is possible to appropriately set warranty conditions for a mobile object such as a vehicle according to the usage conditions of the mobile object by the user.

[0084] (Structure 2) A warranty condition setting system according to Structure 1, wherein the warranty condition setting system has a remaining life consumption degree correction unit, which corrects the remaining life consumption degree based on the usage status of the object movable body by the first user, and the remaining life reduction prediction period calculation unit recalculates the remaining life reduction prediction period based on the corrected remaining life consumption degree, and the warranty condition setting unit re-sets the warranty condition based on the remaining life reduction prediction period calculated by the remaining life reduction prediction period calculation unit according to the corrected remaining life consumption degree.

[0085] According to the warranty condition setting system of configuration 2, the remaining life consumption degree is corrected according to the usage status after the user actually starts using the mobile body, thereby enabling the warranty conditions of the mobile body to be set more appropriately.

[0086] (Structure 3) A warranty condition setting system according to Structure 1 or Structure 2, wherein the remaining life identification unit at the judgment time identifies the remaining life at the judgment time based on the usage history information of the object movable body used by a second user other than the first user when the second user has used the object movable body before the judgment time.

[0087] According to the warranty condition setting system of configuration 3, it is possible to appropriately identify the remaining life at the time of determination based on the actual usage of the target moving body by past users.

[0088] (Structure 4) A warranty condition setting system according to Structure 1 or Structure 2, wherein the remaining life identification unit at the moment of determination identifies the remaining life at the moment of determination according to each of a plurality of object parts possessed by the object movable body, the remaining life consumption degree prediction unit predicts the remaining life consumption degree according to each of a plurality of the object parts, the remaining life reduction prediction period calculation unit calculates the remaining life reduction prediction period according to each of a plurality of the object parts, and the warranty condition setting unit sets the warranty condition of the object movable body based on the remaining life reduction prediction periods of the plurality of the object parts.

[0089] According to the warranty condition setting system of structure 4, since the degree of reduction in the remaining life of each object component varies depending on the usage condition of the object movable body, it is possible to set warranty conditions corresponding to the usage condition of the object movable body by the first user based on the predicted period of reduction in the remaining life of multiple object components.

[0090] (Structure 5) A warranty condition setting method, which is executed by a computer, and the warranty condition setting method includes: a judgment time remaining life identification step, identifying the remaining life of the object movable body at the judgment time, i.e., the judgment time remaining life; a remaining life consumption degree prediction step, based on the usage status of other movable bodies other than the object movable body by a first user who starts using the object movable body after the judgment time, predicting the degree of consumption of the remaining life of the object movable body for each specified period when the first user uses the object movable body, i.e., the remaining life consumption degree; a remaining life reduction prediction period calculation step, assuming that the first user uses the object movable body after the judgment time, calculating the predicted period during which the remaining life of the object movable body decreases from the remaining life at the judgment time to below a specified judgment value based on the remaining life consumption degree; and a warranty condition setting step, setting the warranty condition of the object movable body based on the remaining life reduction prediction period.

[0091] By executing the warranty condition setting method of configuration 5 by a computer, the same operational effects as those of the warranty condition setting system of configuration 1 can be obtained.
