The ECU 24 stores the year of the vehicle 22, body color, and whether genuine manufacturer options such as a sunroof are installed in the ROM, and also stores information on the interior and exterior conditions and repair history in the flash memory.

The ECU 24 stores in flash memory the last time the parts were replaced for parts that are regularly replaced during legal inspections and the like. Examples of parts that are regularly inspected and replaced include engine oil, oil filters, LLC that circulates in the engine cooling system, tires, and the like.

For parts that are replaced irregularly, the ECU 24 stores the usage frequency distribution of each part in a flash memory. Examples of parts that are replaced irregularly include the engine's spark plug, GPF, throttle motor, and turbocharger. For the usage frequency distribution, a histogram of parameters related to the deterioration of each part is created every predetermined time (for example, every few milliseconds) after the vehicle 22 was manufactured, and the histogram is stored in the flash memory. For example, in the case of the distribution of the usage frequency of spark plugs, the engine operating points (engine speed and load factor (engine speed and load factor per engine cycle) every predetermined time (for example, every few msec) after the vehicle 22 was manufactured A histogram of points determined from the ratio of the volume of air actually taken in in one cycle to the stroke volume is created, and the histogram is stored in a flash memory.

The ECU 24 controls the display 28 so that a predetermined display is displayed on the display 28. FIG. 2 is an explanatory diagram showing an example of the display on the display 28. As shown in FIG. A tab 280 is displayed on the display 28, and "value display" is written on the tab 280. When the tab 280 is pressed, a tab press signal Spush is output from the display 28 to the ECU 24.

The DCM 26 transmits information about the vehicle 22 to the data analysis server 30, used car information server 32, and dealer server 34, and receives various information from the data analysis server 30, used car information server 32, and dealer server 34. or

The data analysis server 30 is configured as a well-known computer installed in a data management center, and includes a CPU, ROM, RAM, flash memory, storage device (for example, HDD, SSD, etc.), input/output ports, communication ports, etc. Be prepared. The data analysis server 30 exchanges information with the vehicle 22 and the used car information server 32 through wired or wireless communication.

Various programs such as a used car sales program are installed in the dealer server 33. The used car sales program is a program that displays information on used cars for sale on an information terminal (not shown) in the dealership and updates a web page containing information on used cars for sale.

The mobile terminal 36 is configured as a smartphone, a tablet terminal, or the like. The mobile terminal 36 is carried by a user different from the user of the vehicle 22, and exchanges information with the store server 34 by wireless communication. Various applications such as an application for purchasing a used car are installed on the mobile terminal 40. The used car purchase application is an application for accessing a web page updated by the dealer server 33 and displaying information on used cars for sale on the mobile terminal 36.

Next, the operation of the used car trading system 20 configured in this way will be explained. FIG. 3 is a flowchart showing an example of processing executed by the data analysis server 30, the ECU 24 of the vehicle 22, and the used car information server 32. These processes are executed at predetermined intervals.

First, the ECU 24 of the vehicle 22 transmits vehicle data Datav stored in the ROM to the data analysis server 30 (step S100). The vehicle data Datav is a set of multiple data that affects the used car price of the vehicle 22. Data that affects the used car price of Vehicle 22 include the model year and body color of Vehicle 22, the presence or absence of genuine manufacturer options such as a sunroof, information on the interior and exterior condition and repair history, and the total mileage of Vehicle 22. Examples include Dt, the last time the parts that are replaced regularly for legal inspections were replaced, and the frequency distribution (histogram) of parts that are replaced irregularly.

The data analysis server 30 that has received the vehicle data Datav creates vehicle value information Imfv using the received vehicle data Datav, transmits the created vehicle value information Imfv to the used car information server 32 (step S110), and processes it. end. The vehicle value information Imfv includes vehicle information and health status information of the vehicle 22. The vehicle information includes the model year and body color of the vehicle 22, whether genuine manufacturer options such as a sunroof are installed, information on the interior and exterior conditions and repair history, and the total mileage Dt of the vehicle 22. The health condition information of the vehicle 22 includes the last time when parts that are regularly replaced in legal inspections and the like were last replaced, and the remaining life of parts that are replaced irregularly. The remaining life of a part that is replaced irregularly is based on the usage frequency distribution of the part and a prediction model of the usage frequency distribution of the part when the current user of the vehicle 22 uses the vehicle 22 in the future. , the remaining mileage is estimated as the mileage required for the part to reach a state where replacement is recommended, and the estimated remaining mileage is taken as the remaining life.

The used car information server 32 that has received the vehicle value information Imfv inputs the market price database DB (step S120). The market price database DB identifies factors that change the selling price when selling the vehicle 22 in the current used car transaction market (for example, whether it is a limited edition car, whether it is a limited edition car, whether it is a popular car model or not). This is a database of market prices of cars (e.g.) and fluctuating amounts, which fluctuate depending on transaction results and distribution conditions in the current used car market. For example, when the vehicle 22 is a limited edition car, the used car price may be increased compared to when the vehicle 22 is not a limited edition car.

Subsequently, a price reference value Pss is calculated as a reference value for the price when the vehicle 22 is sold as a used car (step S130). The price reference value Pss is calculated by adding a fluctuation value Pv1 based on transaction results and distribution circumstances in the used car market to a standard price Pvb based on vehicle information, and adding a fluctuation value Pv2 based on the health condition of the vehicle 22. .

The standard price Pvb is a basic price element that does not change as long as the type of vehicle 22 is the same regardless of the individual vehicle 22, and is the first price Pr1 determined based on the model year and total mileage Dt of the vehicle 22. The price is set by adding a second price Pr2 based on whether genuine manufacturer options are installed or not, and a third price Pr3 based on the interior/exterior condition and the scale of repair (=Pr1+Pr2+Pr3). The first price Pr1 is set so that when the vehicle 22 is older, it is cheaper than when it is newer, and when the total mileage Dt is longer, it is cheaper than when it is shorter. The second price Pr2 is set to be lower when the genuine manufacturer option is not installed than when it is installed. The third price Pr3 is set to be cheaper when the interior and exterior are in poor condition than when they are in good condition, and to be cheaper when the past repair of the vehicle 22 is large in scale than when it is small. The second and third prices Pr2 and Pr3 are set to negative values when they are to be reduced.

The fluctuation value Pv1 is a price element that fluctuates depending on the market price of the used car transaction market depending on the individual vehicle 22, and is set based on the equipment of the vehicle 22 and the market price database DB. is set to The market price database DB is a price element whose sale price fluctuates in the current used car transaction market (for example, limited edition cars, limited grades, popular car models), so it changes every moment.

The variable value Pv2 is a price element that changes depending on the health condition of the vehicle 22, and is set to be higher when the health condition of the vehicle 22 is good than when it is bad, and is set to a negative value when reducing the price. be done. The fluctuation value Pv2 changes from moment to moment depending on the health condition of the vehicle 22.

When the used car information server 32 calculates the price reference value Pss, the price reference value Pss becomes a predetermined value from the price reference value Pss (previous Pss) set when step S130 was previously executed within a predetermined time (for example, within several minutes). It is determined whether there has been a change (increase or decrease) by the amount of change dPss or more (step S140). The predetermined variation amount dPss is a threshold value for determining whether the price reference value Pss has changed significantly. When the price reference value Pss does not fluctuate by the predetermined fluctuation amount dPss or more, the process ends.

When the price reference value Pss fluctuates by the predetermined fluctuation amount dPss or more in step S140, the used car information server 32 uses the fluctuated price element of the standard price Pv, fluctuation values Pv1, and Pv2 as information and displays the vehicle 22 as the fluctuation factor Rv. (step S150), and the process ends.

The ECU 24 of the vehicle 22 determines whether or not the fluctuation factor Rv has been received (step S160). If the variation factor Rv has not been received, the process ends. When the fluctuation factor Rv is received, a message 282 indicating that the value of the vehicle 22 in the used car trading market is fluctuating and the fluctuation factor Rv is displayed on the display 28 (step S170), and the process ends. . FIG. 4 is an explanatory diagram showing an example of the display of the message 282. In step S170, when the fluctuation factor Rv is the standard price Pvb, a character string ``There has been a change in the residual value of your car due to a change in the standard price'' is displayed on the display 28 as a message 282. When the fluctuation factor Rv is the fluctuation value Pv1, a character string ``There has been a change in the residual value of your car due to a change in the trading market'' is displayed on the display 28 as a message 282. When the fluctuation factor Rv is the fluctuation value Pv2, a character string ``There has been a change in the residual value of the beloved car due to a change in the health condition of the beloved car'' is displayed on the display 28 as a message 282. Thereby, the user can be made aware of the timing and reason for the change in the reference price, and the user can be encouraged to consider selling the vehicle 22 at a more appropriate timing.

Furthermore, when the tab 280 on the display 28 is pressed, the ECU 24 of the vehicle 22 receives the price reference value Pss calculated in step S130 from the used car information server 32, and displays it on the display 28. Thereby, the user can recognize the value of the vehicle 22, that is, the price reference value Pss.

Next, the operation when an instruction to consider selling the vehicle 22 is given will be described. FIG. 5 is a flowchart showing an example of processing executed by the ECU 24 of the vehicle 22, the used car information server 32, and the dealer server 34. In these processes, after the process of step S170 is executed, the sale consideration tab is displayed on the display 28 configured as a touch panel, the display 28 detects that the sale consideration tab has been pressed by the user, and a detection signal is sent from the display 28. It is executed when input to the ECU 24.

First, the ECU 24 of the vehicle 22 transmits a sale consideration signal to the used car information server 32 (step S200), and ends the process. The used car information server 32 that has received the sale consideration signal transmits the vehicle value information Imfv and the price reference value Pss transmitted from the data analysis server 30 in step S110 described above to the dealer server 34 (step S210). Finish the process. The dealership server 34 that has received the vehicle value information Imfv and the price reference value Pss starts a used car sales program and displays the vehicle value information Imfv and the price reference value Pss as information on the used car to be sold in a diagram in the dealership. The used car information is displayed on an information terminal that does not use the used car, or the web page containing the used car information is updated (step S220), and the process ends. Through such processing, the vehicle value information Imfv and the price reference value Pss of the vehicle 22 can be made known to the customer of the used car dealership. Such processing is executed when the user of the vehicle 22 presses the sale consideration tab displayed on the display 28, so the vehicle value information Imfv and price reference value Pss of the vehicle 22 can be easily obtained at the dealership. can be displayed.

Next, the operation when an instruction to purchase the vehicle 22 is given will be described. FIG. 6 is a flowchart showing an example of processing executed by the ECU 24 of the vehicle 22, the used car information server 32, and the dealer server 34. These processes are performed as a signal instructing the purchase of the vehicle 22 from the mobile terminal 36 by instructing the purchase of the vehicle 22 from a used car purchase application installed on the mobile terminal 36 by a user different from the user of the vehicle 22. The purchase instruction signal is transmitted and executed when the store server 33 receives this purchase instruction signal.

The dealer server 34 that has received the purchase instruction signal sets the purchase price Pb based on the price reference value Pss and transmits it to the used car information server 32 (step S300), and ends the process. As the purchase price Pb, the price reference value Pss may be set as is, or a price higher or lower than the price reference value Pss may be set. The used car information server 32 that has received the purchase price Pb transmits the received purchase price Pb to the vehicle 22 (step S310), and ends the process. The ECU 24 of the vehicle 22 that has received the purchase price Pb displays the purchase request and the purchase price Pb on the display 28 (step S320), and ends the process. The user of the vehicle 22 who visually recognizes such a display is able to consider the purchase price Pb, carry out the procedure for selling the vehicle 22 to the dealership where the used car information server 32 is installed, and then deliver the vehicle 22. In this way, in the used car transaction system 20 of the embodiment, the vehicle 22 remains owned by the user until the user of the vehicle 22 completes the sale procedure. Therefore, it is possible to prevent the vehicle 22 from being parked at the dealership for a long period of time, and it is possible to prevent the dealership from having inventory. This makes it possible to trade used cars efficiently.

According to the used car transaction system 20 of the embodiment described above, when the amount of fluctuation in the calculated price reference value Pss exceeds the predetermined fluctuation amount dPss, it is determined that the price reference value Pss is fluctuating and that the price reference value Pss By transmitting information on the variation factor Rv to the vehicle 22, it is possible to prompt the user to consider selling the vehicle 22 at an appropriate timing.

In the used car trading system 20 of the embodiment, it is determined in step S140 whether or not the fluctuation in the price reference value Pss is actually large. However, in step S140, it may be determined whether the amount of change in the price reference value Pss is expected to exceed the predetermined amount of change dPss, and when it is predicted, the process may proceed to step S150. Examples of times when the amount of variation in the price reference value Pss is expected to exceed the predetermined amount of variation dPss include when the amount of variation in the price reference value Pss is gradually increasing.
