JP7471115B2 - Information processing device, information processing method, and program for used car buying and selling system - Google Patents

Description

The present invention relates to an information processing device, an information processing method, and a program for a used car buying and selling system.

Conventionally, there is known a buying and selling intermediation system that matches sellers and buyers based on product information entered by sellers who wish to sell products and purchase information entered by buyers who wish to purchase products (Patent Document 1).

However, in a sales intermediation system that handles sales between two parties, the potential buyer must decide whether or not to purchase the target product (especially whether the target product is worth the purchase price) based on the product information entered by the potential seller.

Patent Document 2 proposes a technology that allows appraisers to participate in the system. The automobile buying and selling support system proposed in Patent Document 2 requests an appraiser to appraise the target vehicle when a new sales request is registered by a seller, and registers the obtained appraisal result (appraisal amount) in the automobile buying and selling support system.

JP 2005-115434 A JP 2017-16224 A

In the technology proposed in Patent Document 2, an appraiser assesses the target product and provides an objective assessed price, allowing the potential purchaser to determine whether the purchase price is reasonable based on objective information. However, while the technology proposed in Patent Document 2 can alleviate a certain degree of anxiety of the potential purchaser by confirming the product value, it does not confirm the accuracy of the information entered by the seller. In other words, there is a demand for technology in a system that mediates the buying and selling of vehicles that can objectively confirm the accuracy and veracity of the information about the vehicle entered by the potential seller.

In addition, the same reference numbers are used for the same or similar configurations, and duplicate descriptions are omitted.

[System Overview]
1 is a diagram showing an example of the configuration of a used car buying and selling system according to this embodiment. The used car buying and selling system 10 is a system that supports transactions for buying and selling used vehicles between individuals, and includes an information processing device 100, a seller communication device 101 (also simply referred to as communication device 101), a buyer communication device 102 (also simply referred to as communication device 102), and a third party communication device 103 (also simply referred to as communication device 103).

The information processing device 100 is, for example, an information processing server, and executes the operation of the vehicle information provision process (details of which will be described later) of the used car buying and selling system. The information processing device 100 can communicate with each of the communication devices 101, 102, and 103 via a network to send and receive various information.

The information processing device 100 registers information (vehicle information) about vehicles for sale registered by the seller 104, and transmits vehicle information corresponding to a search request or viewing request from the potential buyer 105. In response to a request from the potential buyer 105, the information processing device 100 presents the vehicle information to a third party 106 to confirm the accuracy of the vehicle information. The third party 106 checks and inspects the vehicles put up for sale by the seller 104, confirms the accuracy of the items stated in the vehicle information, checks items related to defects, and creates evaluation information.

The information processing device 100 receives the evaluation information created by the third party 106 and associates it with the corresponding vehicle information. The evaluation information can be viewed upon request from the potential purchaser 105, but part of the evaluation information can be viewed after consent is obtained from the seller 104. For example, the information processing device 100 allows the potential purchaser 105 to view without restriction, the evaluation information, including the results of confirmation of the accuracy of the items described in the vehicle information. On the other hand, the information processing device 100 allows the potential purchaser 105 to view, from the evaluation information, information regarding defects newly discovered by the third party 106 after consent to disclosure is obtained from the seller 104.

The communication device 101 is a communication device used by the seller 104, and may be, for example, a smartphone or a tablet terminal, or may be a personal computer. The communication device 101 transmits information about the vehicle to be put up for sale to the information processing device 100 in response to the operation of the seller 104. The communication device 101 also receives evaluation information created by a third party 106 from the information processing device 100 in response to the operation of the seller 104, and displays it on the display unit. The communication device 101 receives whether or not the seller 104 has agreed to the evaluation information, and transmits information about the agreement to the information processing device 100.

The communication device 102 is a communication device used by the potential purchaser 105, and may be, for example, a smartphone or tablet terminal, or may be a personal computer. It transmits a search request or a viewing request to the information processing device 100 in response to the operation of the potential purchaser 105, and displays the vehicle information, which is the response result from the information processing device 100, on the display unit. The communication device 102 can also transmit information on inquiries and negotiations made to the seller 104 to the information processing device 100, and transmit a request to confirm vehicle information from a third party 106 to the information processing device 100. The communication device 102 also receives at least a portion of the evaluation information created by the third party 106 from the information processing device 100 and displays it on the display unit.

The communication device 102 can receive, in addition to the evaluation information provided by the third party 106, repair cost estimate information, delivery cost estimate information, and the like provided by the third party 106, and display them on the display unit. In response to the operation of the potential purchaser 105, a request for repair or delivery can be made (either via the information processing device 100 or directly).

The communication device 103 is a communication device used by a third party 106, and may be, for example, a smartphone or a tablet terminal, or may be a personal computer. The third party is, for example, a service provider that can provide vehicle maintenance services, such as a vehicle dealer.

[Example of functional configuration of information processing device]
2 is a block diagram showing an example of a functional configuration of the information processing device 100. The control unit 200 includes one or more processors (CPU 201: Central Processing Unit), a ROM (Read Only Memory) 202, and a RAM (Random Access Memory) 203. The CPU 201 reads and executes computer programs (simply referred to as programs) stored in the ROM 202 to control various processes described below. The ROM 202 is a non-volatile storage area, and stores programs corresponding to various processes. The RAM 203 is a volatile storage area, and is used as, for example, a work memory. The control unit 200 may further include a graphics processing unit (GPU), an application specific integrated circuit (ASIC), a dedicated circuit, etc. Furthermore, each component of the control unit 200 may be configured to be virtualized.

The power supply unit 204 supplies external power to the information processing device 100. The communication unit 205 is configured to communicate with the communication devices 101 to 103, etc., via a communication network, and the communication method, communication protocol, etc. are not particularly limited.

[Software configuration of information processing device]
3 is a diagram showing an example of the software configuration of the information processing device 100 according to this embodiment. In this embodiment, each unit is realized by the CPU 201 reading and executing a program stored in the ROM 202 or the like. Note that the software configuration shows only an example of the configuration necessary for implementing this embodiment, and each software configuration such as firmware, OS, middleware, and web service modules is omitted.

The vehicle information acquisition unit 301 acquires information about the vehicle being put up for auction (vehicle information) from the communication device 101. The vehicle information is transmitted from the communication device 101 at the time of registration. In addition, the vehicle information may be transmitted from the communication device 101 in order to add personal information (such as when requesting confirmation of the vehicle information from a third party 106).

The vehicle information, details of which will be described later, includes general information such as the model, year, and grade, information related to defects, and personal information. The vehicle information transmitted from the communication device 101 includes at least general information such as the model and year. Information related to defects and personal information are not required information when registering vehicle information, so they may or may not be included in the vehicle information transmitted from the communication device 101.

The vehicle information management unit 302 writes and reads the vehicle information acquired by the vehicle information acquisition unit 301 to and from the vehicle information DB 310. The vehicle information DB 310 is a database that stores vehicle information.

The evaluation information acquisition unit 303 acquires evaluation information created by the third party 106 from the communication device 103. As will be described in detail later, the evaluation information includes information indicating the accuracy of each item of the vehicle information entered by the seller 104, and information on items similar to those related to defects in the vehicle information. The service information management unit 304 writes and reads service information such as evaluation information, repair cost estimate information, or delivery cost estimate information provided from the communication device 103 of the third party 106 to and from the service information DB 311. The service information DB is a database that stores service information provided by the third party 106, i.e., evaluation information, repair cost estimate information, and delivery cost estimate information.

The additional information acquisition unit 305 acquires the repair cost estimate information and delivery cost estimate information from the service information from the communication device 103 of the third party 106.

The user evaluation value acquisition unit 306 acquires information indicating the evaluation of the seller's 104 transaction from the communication device 102 of the potential purchaser 105. The user evaluation value acquisition unit 306 also acquires information indicating the evaluation of the buyer's 105 transaction from the communication device 101 of the seller 104. The information acquired by the user evaluation value acquisition unit 306 is stored in the user evaluation value DB 312, which stores evaluations of transactions.

The information providing unit 307 acquires information stored in each database through the vehicle information management unit 302, the service information management unit 304, etc., and provides display information to the communication device 101 of the seller 104 and the communication device 102 of the potential buyer 105.

[Vehicle information]
Next, the data format of the vehicle information will be described with reference to FIG. 6. The vehicle information 600 includes a vehicle ID 601, general items 602, items related to defects 603, and personal information 604. The vehicle information shown in FIG. 6 is managed for each vehicle ID, which is an identifier for identifying the vehicle information. The general items 602 are general items that represent the attributes of the vehicle to be put up for sale. The general items 602 include, as sub-items, information on the vehicle model, year, grade, exterior color, interior color, mileage, vehicle inspection expiration date, tires, air conditioner, navigation, aftermarket products, and other accessories, or information on whether they are installed. Usually, the information on the general items 602 is input by the seller 104 using the communication device 101. These items are information used as information indicating the attributes of the vehicle when buying and selling a new or used vehicle, and are not limited to these examples and may be other information. The seller 104 may input the information on defects 603 and personal information 604 using the communication device 101 and transmit them to the information processing device 100.

The vehicle information identified by the vehicle ID may include images, videos, and other VR images of the vehicle, so that the condition of the vehicle being offered for sale can be more accurately understood, either in terms of general matters or matters related to defects. Alternatively, the vehicle information may include questions about the vehicle from the potential buyer 105 and information (comment information) related to the seller's responses to those questions.

[Evaluation information]
Next, the data format of the evaluation information will be described with reference to Fig. 7. The evaluation information 700 includes an evaluation ID 701, general information 702, and information regarding defects 703. The evaluation ID 701 is an identifier for identifying the evaluation information. The general information 702 and the information regarding defects 703 each include, for each sub-item 704, information 705 that the seller has written in the vehicle information, an evaluation result 706 by a third party, and information regarding the presence or absence of consent 707 from the seller 104 to disclosure.

In the example shown in FIG. 7, for the evaluation with evaluation ID "IDz", each piece of information such as {Vehicle model 1, Grade 1, Year 1, Color 1, ...} is stored in the row of information 705. Also, in the row of evaluation result 706 by a third party, "OK" is stored, indicating that the contents written by the seller have been checked by the third party 106 and there are no errors. In other words, in the example shown in FIG. 7, the general information written by the seller 104 was checked by the third party 106 and the results showed that all of the contents were correct.

In addition, in the defect-related item 703, the seller 104 wrote "scratch on P1" for the "information on scratches and dents" in subitem 704, but did not write anything about the "information on possibility of replacement or repair" in subitem 704. On the other hand, in the result of evaluation by a third party (row 706 of evaluation result by a third party), the information "dent on P2" has been added to the "information on scratches and dents" in addition to "scratch on P1". This indicates that the information on scratches and dents that the seller 104 had overlooked (or forgot to write) has been updated to more correct information through confirmation by the third party 106. In addition, through confirmation by the third party 106, information has been added to the "information on possibility of replacement or repair" that "P3 needs to be replaced by XX", indicating that the replacement deadline is approaching. The possibility of replacement or repair is often not known to the actual user (seller), and is added through confirmation by a third party with expertise who can provide vehicle maintenance services. On the other hand, if the potential purchaser 105 can grasp such information before the transaction, they can separately consider the costs of replacement or repair if replacement or repair is required in the near future.

However, if the third party 106 discovers unfavorable information (e.g., information regarding the possibility of replacement or repair) that the seller 104 does not know in the process of checking the vehicle of the seller 104, and the information written by the third party 106 is unconditionally disclosed to the potential buyer 105, this may lead to a disadvantage for the seller 104. Therefore, the seller 104 can set whether or not to consent to the disclosure of each piece of information related to defect matters 703 when evaluation information is written by the third party 106. For example, as shown in FIG. 7, the type of consent can be set for each item of defect matters 703. In this way, in a system that mediates the buying and selling of used cars, the reliability of the seller's information regarding the vehicle can be improved by the third party's confirmation, and disadvantages to the seller that may arise as a result of the confirmation can be suppressed.

[Service Information]
Next, the data format of the service information will be described with reference to Fig. 8. The service information is information that stores information provided by a third party 106 as a business that can provide vehicle maintenance services. The third party 106 can check the condition of the put-up vehicle, as well as provide repair services for parts that need repairs and delivery-related services until the prospective purchaser 105 starts using the purchased vehicle.

As shown in FIG. 8, the service information integrates information provided by a third party 106. In this example, the service ID 805 is managed in association with vehicle information (vehicle ID 801), evaluation information (evaluation ID 802), repair estimate information, and delivery information. In other words, for a given vehicle information, the evaluation information and repair and delivery estimate information can be extracted.

The repair estimate information 803 associates the estimated cost for repairing each defect that the seller 104 has described in the vehicle information (e.g., a scratch in part P1) and each defect that the third party 106 has discovered when inspecting the vehicle (e.g., a dent in part P2). The delivery estimate information 804 also describes the estimated costs for necessary items such as vehicle inspection and registration procedures.

[User evaluation value information]
The user evaluation value information is set for each user and stored in the user evaluation value DB 312 .
The user evaluation value information can be used by both the seller 104 and the prospective purchaser 105 to give an evaluation to the other party after a transaction between them is completed. The evaluation information can be referenced by other users when the seller 104 or the prospective purchaser 105 conducts another transaction.

User evaluation value information is, for example, information that records the user who made the evaluation and the evaluation content for the party receiving the evaluation (the seller 104 in the case where the purchaser 105 is inputting it). For example, when the purchaser 105 inputs user evaluation value information for the seller 104, a user ID that identifies the evaluator (the purchaser 105 in this case) and the evaluation content by the purchaser 105 are associated with the user ID indicating the seller 104. The evaluation content may be, for example, information specifying one of the levels from 1 to 5, or may be information in the form of a comment such as "the response was very prompt," or may be both.

[Example of functional configuration of communication device 101]
Next, a functional configuration example of the communication device 101 used by the seller will be described. FIG. 4 shows a block diagram showing a functional configuration example of the communication device 101. The communication device 102 used by the potential buyer 105 may have the same configuration as the communication device 101. The control unit 410 includes one or more CPUs 411, a ROM 412, and a RAM 413. The CPU 411 reads and executes a program stored in the ROM 412 to control various processes in the communication device. The ROM 412 is a non-volatile storage medium, and stores programs corresponding to various processes. The RAM 413 is a volatile storage medium, and is used as, for example, a work memory. The control unit 410 may further include a GPU, an ASIC, or a dedicated circuit.

Furthermore, the communication device 101 according to this embodiment includes various components that provide an interface for information with the outside world and the power required for the operation of the communication device 101. Each component shown below operates under the control of the control unit 410.

The operation unit 414 accepts various operations on the communication device, and includes, for example, a switch and a touch panel. For example, the operation unit 414 accepts input of vehicle information about the vehicle to be put up for auction (user operation on a vehicle information input screen described below) and an operation to set whether or not to disclose evaluation information by a third party 106 (user operation on a disclosure permission screen described below). The operation unit 141 may also include a software keyboard for entering characters.

The communication unit 415 is configured to communicate with an external device (e.g., the information processing device 100) via a network, and the communication method and communication protocol are not particularly limited. For example, the communication unit 415 transmits vehicle information and settings related to disclosure items to the information processing device 100, and receives evaluation information from a third party 106.

The power supply unit 416 is configured to supply power to each part of the communication device 101, and corresponds to, for example, a battery. The display unit 417 is configured to display an operation menu and various user interfaces related to the listing of a vehicle, and includes a display. The display unit 417 and the operation unit 414 may be configured together as, for example, a touch panel display.

The sensor unit 421 includes various sensors such as a GPS (Global Positioning System) and a camera for detecting the vehicle's own location information. The imaging unit 422 is, for example, a camera, and can capture images of the vehicle being put up for auction.

[Example of functional configuration of communication device 103]
Next, an example of the functional configuration of the communication device 103 will be described. Fig. 5 shows a block diagram showing an example of the functional configuration of the communication device 103. The control unit 510 includes one or more CPUs 511, a ROM 512, and a RAM 513. The CPU 511 controls various processes in the communication device by reading and executing a program stored in the ROM 512. The ROM 512 is a non-volatile storage medium, and stores programs corresponding to various processes. The RAM 513 is a volatile storage medium, and is used as, for example, a work memory.

Furthermore, the communication device 103 according to this embodiment includes various components that provide an interface for information with the outside world and the power required for the operation of the communication device 103. Each component shown below operates under the control of the control unit 510.

The operation unit 514 accepts various operations for the communication device, and includes, for example, a mouse, a keyboard, a touch panel, and the like. In this embodiment, the operation unit 514 is used when the third party 106 checks and inspects the vehicle of the seller 104 and then creates evaluation information based on the results of the inspection.

The communication unit 515 communicates with an external device (e.g., the information processing device 100) via a network, and the communication method and communication protocol are not particularly limited. For example, the communication unit 515 transmits input evaluation information to the information processing device 100 and receives vehicle information input by the seller 104 from the information processing device 100.

The power supply unit 516 is a component that supplies power to each component of the communication device 103, and corresponds to a battery. The display unit 517 is a component that outputs various information such as an operation menu, and includes a display.

[A series of operations in vehicle information provision processing]
Next, a series of operations of the vehicle information provision process executed by the information processing device 100 in the used car buying and selling system will be described with reference to Figures 11A and 11B. Note that this process is performed when the used car buying and selling service provided by the information processing device 100 is in operation and the seller and the potential buyer are each logged in to the service using their own user ID. Note that the operation of each device is realized by the CPU executing a program stored in the ROM of each device.

In S1101, the communication device 101 inputs vehicle information of the vehicle to be put up for sale in accordance with the operation of the seller 104, and transmits it to the information processing device 100. FIG. 9 shows an example of a vehicle information input screen 901 that is displayed on the display unit 417 when the seller 104 inputs vehicle information. The vehicle information input screen 901 is configured to allow input of information corresponding to the vehicle information described above, and includes, for example, a field 902 for inputting general information such as the type of the put-up vehicle, and a field 903 for inputting information related to defects of the put-up vehicle. In the example shown in FIG. 9, for information related to defects, for example, an input field 904 for scratches and an input field 905 for accident history are provided.

Furthermore, the communication device 101 can attach images, videos, and other VR images of the vehicle that have been taken in advance or taken while inputting information to the vehicle information on the vehicle information input screen 901. In S1102, the information processing device 100 acquires the vehicle information from the communication device 101 and stores it in the vehicle information DB 310.

In S1103, the communication device 102 searches for vehicle information through the operation of the prospective buyer 105, and then transmits a viewing request specifying the specific vehicle information. Note that in the sequence diagram shown in FIG. 11A, in consideration of the visibility of the diagram, the process of transmitting a search request from the communication device 102 to the information processing device 100 and transmitting the search results from the information processing device 100 is omitted.

In S1104, the information processing device 100 transmits the specified vehicle information (e.g., by a vehicle information ID) to the communication device 102. In S1105, the communication device 102 receives the target vehicle information and displays the vehicle information on the display unit 417. The potential purchaser 105 can check the general information and any defects in the vehicle information. At this time, if the potential purchaser 105 further requests confirmation by a third party, for example, by pressing a button on the display screen requesting confirmation by a third party, causing the information processing device 100 to send a request for confirmation by a third party.

In S1106, when the information processing device 100 receives the confirmation request from the communication device 102, it notifies the seller 104 and requests evaluation information from the third party 106. Although not shown in FIG. 11A, when the seller 104 receives a notification from the potential purchaser 105 that a confirmation request has been made by a third party, the seller 104 transports the vehicle being offered for sale to a maintenance facility for the third party (for confirmation). The information processing device 100 transmits the vehicle information to be evaluated by the third party 106 to the communication device 103.

In the example of this embodiment, the seller 104 transported the vehicle to a third party in response to receiving a request for evaluation by the third party, but the timing of transporting the vehicle may be other timing. For example, the seller may transport the vehicle to a third party in response to transmitting vehicle information of the vehicle to be put up for sale to the information processing device 100.

In S1107, when the communication device 103 of the third party 106 receives a request for evaluation information from the information processing device 100, it displays the received vehicle information so that the third party can confirm it. After that, when the third party confirms and evaluates the vehicle based on the vehicle information, the communication 102 transmits the evaluation information including the evaluation result to the information processing device 100. For example, when the third party receives the seller's vehicle that has been delivered, the third party confirms and evaluates the vehicle while looking at the vehicle information written by the seller. As described above, if there are no errors in the description of the vehicle information, the third party 106 adds information indicating that there are no errors to the evaluation information. In addition, if the third party 106 discovers a new defect or a condition that may require replacement or repair, it records information about the defect, etc. in the evaluation information.

When buying and selling used cars using the vehicle information provision process according to this embodiment, the seller's vehicle is transported to the third party when an evaluation by a third party is requested. Therefore, after the subsequent processes are completed and the transaction is concluded, there is no need to transport the vehicle to the dealer (i.e., the third party) for delivery procedures, etc. This makes it possible to shorten the time from the conclusion of the transaction to delivery.

The third party also creates estimate information 803 for repairs and estimate information 804 for delivery, as shown in FIG. 8, and transmits them to the information processing device 100. Note that in this embodiment, an example is described in which estimate information for repairs and estimate information for delivery are transmitted to the information processing device 100 at the same time as the evaluation information. However, the prospective purchaser 105 and the third party 106 may further adjust the details of the repairs and delivery procedures at a later time, and the third party 106 may transmit the adjusted estimate to the information processing device 100 to update the information.

In S1108, the information processing device 100 receives the evaluation information and information regarding the quotation from the communication device 102 and stores them in the evaluation information DB and the service information DB, respectively. In addition, the information processing device 100 notifies the seller 104 of the evaluation result in response to storing the evaluation information and quotation information in the DB.

In S1109, the communication device 101 displays a disclosure item consent screen based on the evaluation results from the information processing device 100, and sets the disclosure items according to the seller's instructions. The disclosure item consent screen is, for example, a screen as shown in FIG. 10, and displays the evaluation results 1002 by a third party. The evaluation results by the third party include general items 1003 and defect-related items 1006, and in the general items 1003, confirmation results 1005 for the descriptions of each subitem 1004 are displayed. In the example shown in FIG. 10, the confirmation results 1005 indicate that there were no errors in the information provided by the seller. In addition, in the defect-related items 1006, the confirmation result 1008 indicates that the "scratch on part P1" in item 1007 was confirmed by a third party.

Item 1010 indicates any defects or items that may require replacement or repair that have been newly discovered through a third-party inspection. The seller agrees to disclose such information to potential buyers by operating buttons 1009-1011. In the example shown in FIG. 10, setting a button to ON indicates consent to the disclosure of the corresponding defect. On the other hand, setting a button to OFF indicates not consent to the disclosure of the corresponding defect.

In S1110, the information processing device 100 updates the evaluation information based on the received evaluation information. In S1111, the information processing device 100 transmits the updated evaluation information to the communication device 102 of the potential purchaser.

In S1112, the communication device 102 displays the received evaluation information on the display unit. This allows the prospective purchaser 105 to view the evaluation information confirmed by the third party. The evaluation information displayed by the communication device 102 may have content similar to the disclosure consent screen shown in FIG. 10. For example, display items 1002 to 1009 may be displayed, and of the evaluation information in 1010, the description up to "dent in P2" that the seller agreed to may be displayed. In this way, the evaluation information can be viewed while comparing the items described by the seller with the third party's evaluation results (check marks and new defects noted).

In S1113, if the potential purchaser 105 decides to purchase the vehicle while viewing the evaluation information, the communication device 102 transmits information indicating a transaction offer to the information processing device 100 in response to an operation by the potential purchaser 105.

In S1114, when a transaction is concluded with the seller based on the transaction application from the communication device 102, the information processing device 100 transmits information indicating the conclusion of the transaction to the communication device 101 of the seller 104 and the communication device 103 of the third party. By notifying the third party of the transaction, the third party 106 can promptly begin work such as replacement and repair, or work for delivery, after the transaction is concluded. In other words, it is possible to shorten the time until delivery, compared to when the potential buyer contacts the buyer individually.

When a transaction for a vehicle is completed, the information processing device 100 acquires information indicating the seller's evaluation of the transaction and information indicating the buyer's evaluation of the transaction from each communication device, and updates the evaluation information for each user's transaction based on the acquired evaluation information. The evaluation information for the transaction is used as information indicating the reliability of the user when the user makes another transaction.

As described above, in this embodiment, the vehicle information written by the seller is evaluated by a third party, and the evaluation results are obtained. Then, from the evaluation result information, predetermined information including the evaluation results regarding vehicle defects is transmitted to the communication device of the prospective buyer. In addition, the predetermined information including the evaluation results regarding vehicle defects is controlled based on the seller's consent. In this way, vehicle information in which the accuracy or veracity of the defect-related matters cannot be obtained can be provided as more reliable information. In other words, in a system that mediates the buying and selling of used cars, it is possible to improve the reliability of the information regarding the vehicle provided by the seller.
