[0008] We can provide an information processing device that provides information about how used a used car has been. [Brief explanation of the drawing]

[0009] [Figure 1] This figure shows an example configuration of a used car information provision system according to this embodiment. [Figure 2] This is an example of a functional block diagram of the various components in a used car information provision system. [Figure 3] This is an example of a sequence diagram illustrating the flow of processes or operations performed by a user purchasing a used car, a used car dealership, and a used car information center. [Modes for carrying out the invention]

[0010] The following describes a used car information provision system and an information provision method performed by the used car information provision system as an example of an embodiment for carrying out the present invention.

[0011] <Example System Configuration> Figure 1 shows an example configuration of the used car information provision system 100 according to this embodiment. First, the used car dealership and the used car information center are in partnership. The used car dealership's server device 30 and the used car information center's server device 50 can communicate with each other. A user who wants to purchase a used car operates the terminal device 10 to connect to the server device 50 operated by the used car information center and displays a web page about the desired used car.

[0012] In this configuration, the used car information provision system 100 of this embodiment processes or operates as follows.

[0013] (1) The used car dealership operator's server device 30 stores vehicle condition information and attribute information about the previous vehicle owner in association with the used car information center's server device 50. Attribute information includes individual / corporate status, gender, age, or driving history.

[0014] (2) When the used car information center's server device 50 receives a vehicle inquiry request from the terminal device 10 operated by the user, the used car information center's server device 50 provides the terminal device 10 with not only vehicle information but also attribute information about the previous vehicle owner himself.

[0015] Therefore, users of the used car information provision system 100 of this embodiment can make a decision on whether or not to purchase a used car after understanding personal attribute information. Users can understand how the used car was used and what kind of person (corporate / individual, gender, age, driving history, etc.) used it. Therefore, the used car information provision system 100 can provide a sense of security to customers considering purchasing a used car.

[0016] Referring to FIG. 1, the system configuration of the used car information providing system 100 will be described. The used car information providing system 100 is a system that supports the transaction of used cars when they are traded. Support means, for example, enabling the search for used cars, providing information on each used car, and introducing used car dealership operators. The used car information providing system 100 includes a terminal device 10, a server device 30 of a used car dealership operator, and a server device 50 of a used car information center. However, the terminal device 10 does not necessarily need to be always connected to the network N1.

[0017] The terminal device 10 and the server device 30 of the used car dealership operator communicate via the network N1. The network N1 in this embodiment is a network using a public line such as 3G, 4G, 5G, or LTE. A public line is a communication line connecting bases, in which unspecified users physically share the same line for use. For example, a mobile phone network and a PHS communication network can be mentioned. In addition, the terminal device 10 can also connect to an access point via a wireless LAN such as Wi-Fi (registered trademark) and communicate with the information processing system 20 via the Internet.

[0018] The server device 30 of the used car dealership operator and the server device 50 of the used car information center communicate via the network N2. The network N2 in this embodiment is assumed to be a LAN constructed in a facility where these server devices are installed, a WAN having a plurality of LANs, the Internet, etc. The server devices 30 and 50 do not necessarily need to be constructed in the same LAN, and the network N2 may be a VPN (Virtual Private Network), a wide area Ethernet (registered trademark), etc. It is only necessary for these server devices 30 and 50 to be able to communicate. The network N2 may be constructed either wired or wirelessly, or may be a combination of wired and wireless.

[0019] The terminal device 10 has functions as a computer, such as the function of sending a used car inquiry request input by the user to the server device 50 of the used car information center, and the function of displaying detailed information of the queried used car (for example, a web browser). Also, as one aspect of the inquiry, the terminal device 10 has the function of sending a used car search request to the server device 50 of the used car information center, and obtaining and displaying a list of used cars that match the search in a list.

[0020] Also, the used car dealership operator may use the terminal device 10. In this case, the terminal device 10 sends the vehicle information input by the used car dealership operator and the attribute information of the previous vehicle owner to the server device 50 of the used car information center. Note that a web browser may operate on the terminal device 10, or a dedicated native app may operate on the used car information center.

[0021] Specifically, the terminal device 10 includes, but is not limited to, smartphones, mobile phones, tablet terminals, car navigation systems, game consoles, PDAs (Personal Digital Assistants), digital cameras, PCs (Personal Computers), wearable PCs such as wristwatch types, and game consoles.

[0022] A used car dealership operator is an operator who conducts used car sales contracts using an EC site or face-to-face customer service. The server device 30 of the used car dealership operator is, for example, one or more information processing devices on the Internet. A server is a computer or software that fulfills the function of providing information and processing results in response to requests from clients. Also, the server device 30 of the used car dealership operator may support cloud computing. Cloud computing refers to a usage form in which resources on a network are used without being aware of specific hardware resources.

[0023] The used car information center's server device 50 is one or more information processing devices on the Internet that hold vehicle information and attribute information of the previous vehicle owner. The used car dealer's server device 30 registers vehicle information and attribute information of the previous vehicle owner related to the used car dealer that it has purchased with the used car information center's server device 50. Note that used car dealers are not necessarily required to purchase used cars; they may also act as intermediaries and register vehicle information and attribute information of the previous vehicle owner related to the used car dealer with the used car information center's server device 50.

[0024] The Used Car Information Center maintains a centralized, searchable database of used car information collected from multiple used car dealerships. The Used Car Information Center then introduces users with a high probability of purchasing a used car to the relevant dealership. The Used Car Information Center may also function as a used car sales system, allowing for the entire used car sale to be completed on an e-commerce website.

[0025] The used car information center's server device 50 responds to used car inquiry requests sent from the terminal device 10 by returning vehicle information and attribute information of the previous vehicle owner to the terminal device 10. The used car information center's server device 50 also searches for vehicle information and attribute information of the previous vehicle owner based on the search criteria sent from the terminal device 10 and returns the search results to the terminal device 10.

[0026] Furthermore, information processing devices that provide information, such as the server device 50 of the used car information center, are sometimes called file servers. The server device 50 of the used car information center has storage for saving vehicle information and attribute information of the previous vehicle owner. This storage may also be storage used in a service that provides disk space on the internet to users. Storage for saving vehicle information and attribute information of the previous vehicle owner is sometimes called online storage (whether paid or free).

[0027] The server device 30 of the used car dealership and the server device 50 of the used car information center may be implemented as a single information processing device. Alternatively, the server device 50 of the used car information center may be an HDD or SSD (Solid State Drive) built into or attached to the server device 30 of the used car dealership.

[0028] <Hardware Configuration> The terminal device 10, the used car dealer's server device 30, and the used car information center's server device 50 can all be general-purpose computers. The computer is equipped with a CPU, ROM, RAM, HDD, display, external device connection interface, network interface, bus line, keyboard, pointing device, optical storage drive, media interface, etc.

[0029] The terminal device 10 is equipped with an OS such as Windows®, MacOS®, Android®, or iOS®, and runs a web browser or a dedicated native application on the used car dealer's server device 30 or the used car information center's server device 50. The user operates the web browser or native application to display information obtained from the used car dealer's server device 30 on the terminal device 10.

[0030] The server devices 30 of the used car dealership and 50 of the used car information center are equipped with Windows®-based server OS, Unix®-based server OS, etc., and provide information and perform processing in response to requests from the terminal device 10.

[0031] <About the features> Figure 2 shows a functional block diagram of each device in the used car information provision system 100 of this embodiment.

[0032] <<Regarding the functionality of server equipment for used car dealerships>> The used car dealership's server device 30 includes a communication unit 31, a screen generation unit 32, and an information registration unit 33. Each of these functional units in the used car dealership's server device 30 is a function or means realized by the operation of computer components by instructions from the CPU according to a program deployed from the HDD to RAM.

[0033] The communication unit 31 connects to the network N1 and transmits and receives various types of data with the terminal device 10. In this embodiment, the communication unit 31 mainly receives requests from the terminal device 10 for information acquisition and registration, and sends the information and processing results (screen information displayed by the terminal device 10) corresponding to the request to the terminal device 10 as a response.

[0034] The screen generation unit 32 generates screen information for the screen displayed by the terminal device 10. The screen information is a program written in HTML, XML, a scripting language (e.g., JavaScript®), and CSS (Cascading Style Sheet), etc., with HTML mainly specifying the structure of the web page, the scripting language defining the behavior of the web page, and CSS specifying the style of the web page. When a native application is running on the terminal device 10, the native application maintains the screen configuration, so the screen generation unit 32 transmits the content to be displayed.

[0035] The information registration unit 33 registers the vehicle information of the used car and attribute information about the previous vehicle owner entered by the used car dealer to the server device 50 of the used car information center. The used car dealer may enter the vehicle information and attribute information about the previous vehicle owner from the terminal device 10, or they may directly enter the vehicle information and attribute information about the previous vehicle owner by operating the console of the used car dealer's server device 30. Alternatively, the used car dealer may enter the vehicle information and attribute information about the previous vehicle owner into the terminal device 10, and the terminal device 10 may transmit this information to the used car dealer's server device 30.

[0036] <<About the functions of the used car information center's server equipment>> The used car information center's server device 50 includes a communication unit 51, a screen generation unit 52, an information registration reception unit 53, a search unit 54, and an information storage unit 55. Each of these functional units in the used car information center's server device 50 is a function or means realized by computer components operating according to instructions from the CPU based on a program deployed from the HDD to RAM. The information storage unit 55 is built on computer components such as the HDD and RAM.

[0037] First, the functions of the communication unit 51 and the screen generation unit 52 can be the same as those of the server device 30 of a used car dealership.

[0038] The information registration receiving unit 53 receives registration of vehicle information and attribute information about the previous vehicle owner from the information registration unit 33. In other words, the information registration receiving unit 53 receives the vehicle information and attribute information about the previous vehicle owner transmitted from the information registration unit 33 and stores it in the information storage unit 55.

[0039] The search unit 54 searches for used car vehicle information stored in the information storage unit 55 using the search conditions specified by the user. The search unit 54 may also search for attribute information about the previous vehicle owner.

[0040] The screen generation unit 52 generates a screen based on the search results from the search unit 54. Search conditions include, but are not limited to, vehicle type, vehicle name, year of manufacture, price, mileage, and various options (car navigation, advanced safety equipment, rearview monitor, smart entry system, automatic folding door mirrors, floor mats, sunroof, remote engine starter).

[0041] <<Vehicle Information>> This section explains vehicle information. Vehicle information includes information about the vehicle's condition, such as maintenance and driving history. Examples of vehicle information include accident history, flood history, recall history, warning light illumination history, mileage, driving frequency (number of rides per month, etc.), maintenance history, actual fuel efficiency, and drive battery condition (hybrid or electric vehicle). Maintenance history includes replacements of engine oil, oil filter, brake fluid, spark plugs, lead-acid battery, and drive battery.

[0042] Next, we will explain the attribute information of the previous vehicle owner. The attribute information of the previous vehicle owner is information used to identify what kind of person the previous owner of the used car was, without including personal information. The attribute information of the previous vehicle owner may also include how the vehicle was used. This is because the driver's attributes are often reflected in how the vehicle was used. The attribute information of the previous vehicle owner may include, for example, whether the owner is an individual or a corporation, gender, age, driving history (how the vehicle was used), etc. In addition, the attribute information of the previous vehicle owner may include smoking history, traffic violation history, or whether or not they have a gold driver's license, etc.

[0043] From a user's perspective, knowing that the previous vehicle owner was a corporation indicates that the vehicle was used relatively frequently. From a user's perspective, knowing that the previous vehicle owner was a woman indicates that the vehicle was used relatively carefully. From a user's perspective, knowing that the previous vehicle owner was elderly indicates that the vehicle was used relatively carefully.

[0044] Driving history includes factors such as the degree of sudden acceleration, sudden braking, sharp turns, the degree of speed limit violations, frequency of driving in rain or snow, frequency of driving on mountain roads, and frequency of driving along the coast. While this is objective information, it is related to attribute information about the previous vehicle owner's preferred driving style. The degree of sudden acceleration can be measured by, for example, the average acceleration from zero (or near zero) to a certain speed, the highest daily value, and the frequency of exceeding a threshold. A previous vehicle owner who preferred sudden acceleration may have been putting excessive stress on the vehicle. The degree of sudden braking can be measured by, for example, the average deceleration from when the vehicle speed falls below a certain level until it reaches zero (or nearly zero), the highest value per day, or the frequency of exceeding a threshold. A previous vehicle owner who frequently performed sudden braking may have been putting excessive stress on the vehicle. The degree of sharp turns can be measured by factors such as the daily maximum value of lateral acceleration and the frequency of exceeding the threshold. A previous vehicle owner who favored sharp turns may have been putting excessive stress on the vehicle. The severity of a speed limit violation is determined by the frequency with which the actual vehicle speed exceeded the legal speed limit when the vehicle obtained the legal speed limit from image capture of road signs or the navigation system, and the maximum amount of the speed limit exceedance. A previous vehicle owner who frequently exceeded the legal speed limit may have been putting excessive stress on the vehicle. The frequency of driving in rain or snow depends on the weather information the vehicle receives from external sources while it is in motion. On rainy or snowy days, the wipers are activated, water droplets can enter the vehicle, and freezing is more likely to occur, putting a strain on the vehicle. Mountain roads are often narrow and unpaved, so frequent driving on them can easily cause minor scratches. Whether or not a vehicle has driven on mountain roads can be determined from location information and the navigation system. • The seashore has a high salt content, and frequent driving along the coast can easily damage metal parts. Whether or not a vehicle has driven along the coast can be determined from location information and the navigation system.

[0045] As a user, you can infer how much stress the vehicle has been subjected to based on the previous owner's driving history and other attribute information.

[0046] Furthermore, information such as vehicle acceleration, deceleration, lateral acceleration, and vehicle speed can be obtained via CAN (Controller Area Network) data and is stored by the vehicle as needed.

[0047] <<About the functions of the terminal device>> The terminal device 10 includes a communication unit 11, a display control unit 12, and an operation reception unit 13. Each of these functional units of the terminal device 10 is a function or means realized by any of the components of the computer operating according to instructions from the CPU in accordance with a program (web browser or native application) deployed from the HDD to RAM.

[0048] The communication unit 11 connects to the network N1, sends various HTTP requests to the information processing system 20, and receives HTTP responses. As described above, the communication unit 11 connects to public networks (3G / 4G / LTE, etc.) or wireless LANs, etc., and receives screen information for used car search screens and detailed screens for each used car. The terminal device 10 may be used not only by users but also by used car dealerships. In this case, the communication unit 11 sends vehicle information and attribute information of the previous vehicle owner to the used car information center server device 50.

[0049] The display control unit 12 generates the UI (user interface) screen and displays it on the display. The display control unit 12 may be implemented by a web browser.

[0050] The operation reception unit 13 receives various operations for the terminal device 10. For example, the operation reception unit 13 receives search conditions entered by the user, as well as vehicle information and attribute information of the previous vehicle owner entered by the used car dealership operator.

[0051] <Action or process> Next, Figure 3 will be used to explain the processes or operations performed by the used car information provision system 100. Figure 3 is a sequence diagram illustrating the flow of processes or operations performed by a user purchasing a used car, a used car dealership, and the used car information center. The processes in Figure 3 include the processes of the terminal device 10 and the server devices 30 and 50.

[0052] <<Conventional processing or operation>> First, let's explain how to view used car information in the traditional way, where the attribute information of the previous vehicle owner is not registered. The user profile of a used car buyer is one that is concerned with details such as who drove the car before, whether it was a corporation or not, and how the car was used.

[0053] S1: First, the used car dealership enters into a sales contract with the previous vehicle owner for the used car. In this case, the used car dealership purchases the used car from the previous vehicle owner.

[0054] S2: The used car dealership obtains vehicle information from the previous owner who wishes to sell the vehicle, after obtaining their consent for the appraisal. The used car dealership then obtains vehicle information that is generally available from the vehicle to be appraised. The used car dealership registers the vehicle information on the used car dealership's server device 30. The used car dealership may use the terminal device 10 or register the vehicle information directly on the server device 30.

[0055] S3: The user connects the terminal device 10 to the used car dealer's server device 30 and performs an operation to display a web page about used cars provided by the used car dealer's server device 30. The operation reception unit 13 of the terminal device 10 receives the operation, and the communication unit 11 sends a used car inquiry request to the used car dealer's server device 30.

[0056] S4: The communication unit 31 of the used car dealer's server device 30 receives an inquiry request, the screen generation unit 32 generates a screen from existing used car information (vehicle information only), and the communication unit 31 transmits the screen information to the terminal device 10. The communication unit 11 of the terminal device 10 receives the screen information, and the display control unit 12 displays the search results and detailed information of each used car. Conventionally, only the vehicle information of the used cars is displayed, but users can select a used car by viewing this information.

[0057] <<Processing or operation of this embodiment>> Next, we will describe how to inquire about and view used car information in this embodiment, which allows users to view attribute information of the previous vehicle owner.

[0058] S11, S12: The processing in steps S11 and S12 may be the same as in steps S1 and S2.

[0059] S13: The used car dealership operator registers the attribute information of the previous vehicle owner in the used car dealership operator's server device 30. Of the attribute information of the previous vehicle owner, whether it is an individual or a corporation, gender, and age are clear from the contract documents. Driving history is obtained by extracting and analyzing CAN data from the vehicle using a prescribed tool. The used car dealership operator may use the terminal device 10 or register the vehicle information directly in the server device.

[0060] S14: The information registration unit 33 of the used car dealership's server device 30 registers vehicle information and previous vehicle owner attribute information with the used car information center's server device 50. The information registration reception unit 53 of the used car information center's server device 50 receives the vehicle information and previous vehicle owner attribute information, associates them, and stores them in the information storage unit 55.

[0061] S15: Next, a user who wants to purchase a used car connects terminal device 10 to the used car dealer's server device 30 and displays the portal site's web page (service startup).

[0062] S16: The user inputs an operation to inquire about used cars into the terminal device 10. That is, the user inputs search conditions as part of the inquiry operation. The operation reception unit 13 receives the operation.

[0063] S17: The communication unit 11 of the terminal device 10 sends an inquiry request along with the search conditions to the server device 50 of the used car information center. The communication unit 51 of the server device 50 of the used car information center receives the inquiry request, and the search unit 54 searches for vehicle information using the search conditions. If the user can include attribute information of the previous vehicle owner in the search conditions, the search unit 54 may also search for the attribute information of the previous vehicle owner. The user can narrow down the used cars using the desired attribute information of the previous vehicle owner. The user may also search for used cars using only the attribute information of the previous vehicle owner.

[0064] The communication unit 51 of the used car information center's server device 50 transmits screen information generated by the screen generation unit 52 from the search results (including vehicle information and attribute information of the previous vehicle owner) to the terminal device 10.

[0065] S18: The communication unit 11 of the terminal device 10 receives screen information including search results, and the display control unit 12 displays the search results. The user can view not only vehicle information but also attribute information of the previous vehicle owner to confirm what kind of previous owner had driven the vehicle.

[0066] S19: If the user finds a used car they like, they purchase it. At the time of purchase, the user goes to the used car dealership that handles the used car and concludes a prescribed sales contract. The user may also complete the used car purchase procedure by communicating with the server device 50 of the used car information center.

[0067] Next, we will explain the cases in which users sell their used cars for various reasons (such as no longer needing the car or needing a different vehicle).

[0068] S21: Users bring their used cars to used car dealerships, have them appraised, and then sell them.

[0069] S22: The used car dealership enters into a sales contract with the user (current owner) for the used car. In this case, the used car dealership purchases the used car from the current owner.

[0070] S23: Used car dealership operators register vehicle information that is generally available to the public on their server device 30. Used car dealership operators may use terminal devices 10 or register vehicle information directly on the server device.

[0071] S24: The used car dealership operator registers the current owner's attribute information on the used car dealership operator's server device 30. The used car dealership operator may use the terminal device 10 or register the vehicle information directly on the server device.

[0072] In this way, each time a vehicle changes ownership, the previous owner's attribute information is registered with the used car information center, allowing the next user to check the previous owner's attribute information and decide whether or not to purchase the used car.

[0073] <Main effects> Users of the used car information provision system 100 of this embodiment can make a decision on whether or not to purchase a used car after understanding personal attribute information. Users can understand how the used car was used and what kind of person (corporate / individual, gender, age, driving history, etc.) used it. Therefore, the used car information provision system 100 can provide a sense of security to customers considering purchasing a used car.

[0074] <Other application examples> Although the best mode for carrying out the present invention has been described above using examples, the present invention is not limited in any way to these examples, and various modifications and substitutions can be made without departing from the spirit of the present invention.

[0075] For example, a used car dealership operator's server device 50 may provide the terminal device 10 with attribute information of all past owners, not just the most recent owner. In this case, the information storage unit 55 stores the attribute information in association with the vehicle identification number (a unique identification number assigned to each vehicle), which does not change even if the owner changes.

[0076] The previous vehicle owner may register their own attribute information in the attribute information of the previous vehicle owner. For example, the previous vehicle owner connects terminal device 10 to the used car information center's server device 50 and displays the input screen for the attribute information of the used car they sold. Since the used car dealer has access rights to the input screen for the used car they sold, the previous vehicle owner may input under the supervision of the used car dealer, or they may be given a temporary password. The previous vehicle owner inputs their own attribute information. The previous vehicle owner may, for example, input a self-introduction in free writing, or input by answering a personality test that affects driving. [Explanation of Symbols]
