Description

[Technical Field]

[0001] The present invention relates to an information processing device, an information processing method, and an information processing program, and more particularly to an information processing device, an information processing method, and an information processing program for searching for information on vehicle parts used in a vehicle. [Background technology]

[0002] Conventionally, a system has been known that stores inventory information for vehicle parts used in vehicles, searches for and outputs information on specific vehicle parts, and thereby establishes transactions between parts providers that provide vehicle parts and parts users who need the vehicle parts, thereby supporting the distribution of vehicle parts. For example, as shown in Patent Documents 1 and 2, a used parts distribution system has been proposed that supports all aspects of business transactions for both parts providers and parts users in order to promote the buying and selling of used vehicle parts. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-203998 [Patent Document 2] Japanese Patent Application Laid-Open No. 2011-164940 Summary of the Invention [Problem to be solved by the invention]

[0004] In particular, Patent Document 1 describes that inventory information regarding used parts can be viewed on a web page, and that when information specifying a used part is entered, a search is made for a used part that matches the information in an inventory database. Furthermore, Patent Document 2 describes displaying a smart catalog of automobile parts that allows a user to select vehicle parts that are necessary for repair or replacement during vehicle maintenance, or vehicle parts that may need to be repaired or replaced. As mentioned above, these patent documents merely describe how to support general business transactions for both parts providers and parts users, and further ingenuity and operations are required to search for more appropriate information about vehicle parts.

[0005] An object of the present invention is to provide an information processing device, an information processing method, and an information processing program that enable easy retrieval of appropriate vehicle part information as needed. [Means for solving the problem]

[0006] The above problem is solved by an information processing device of the present invention, which includes a memory unit that stores vehicle parts used in a vehicle for each vehicle type of the vehicle, an identification unit that identifies the vehicle type of the vehicle, a part identification unit that identifies the vehicle parts stored in the memory unit for the identified vehicle type, a search unit that searches for information on the vehicle parts using search conditions in which at least one of a first search item that searches for vehicle parts based on information on the part type of the identified vehicle part and a second search item that is different from the first search item and limits the vehicle parts more than the first search item is set to be enabled, and an output unit that outputs the information of the vehicle parts searched for by the search unit, and when an update of information on the identified vehicle part satisfies a search item change condition, the search unit searches for information on the identified vehicle part using search conditions in which the first search item is set to be enabled out of the first search item and the second search item.

[0007] As described above, the information processing device searches for information on vehicle parts using search conditions in which at least one of a first search item and a second search item that more narrows down the vehicle parts than the first search item is set to be active. Then, when an update to information on the identified vehicle part satisfies the change condition for the search item, the information processing device searches for information on the identified vehicle part using search conditions in which the first search item is set to be active. In other words, when information on the identified vehicle part is updated and the content of the update satisfies the change condition for the search item, the information processing device can search for information on the vehicle part using search conditions based on the first search item. By enabling different search items in this way, it becomes easier to search for information on vehicle parts. For example, when information on a vehicle part is updated, a parts user can search for and check the updated vehicle part.

[0008] Furthermore, according to an information processing method of the present invention, the above problem is solved by a computer having a memory unit that stores vehicle parts used in a vehicle for each vehicle type of the vehicle, identifying the vehicle type of the vehicle, specifying the vehicle parts stored in the memory unit for the identified vehicle type, searching for information on the vehicle parts using search conditions in which at least one of a first search item that searches for vehicle parts based on information on the part type of the identified vehicle part and a second search item that is different from the first search item and limits the vehicle parts more than the first search item is set to be enabled, and outputting the searched information on the vehicle parts, and when searching for information on the vehicle parts, when an update of information on the identified vehicle part satisfies a search item change condition, searching for information on the identified vehicle part using search conditions in which the first search item of the first search item and the second search item is set to be enabled.

[0009] Furthermore, according to an information processing program of the present invention, the above problem is solved by having a computer as an information processing device having a memory unit that stores vehicle parts used in a vehicle for each vehicle type of the vehicle execute the following processes: identifying the vehicle type of the vehicle; specifying the vehicle parts stored in the memory unit for the identified vehicle type; searching for information on the vehicle parts using search conditions in which at least one of a first search item that searches for vehicle parts based on information on the part type of the identified vehicle part and a second search item that is different from the first search item and limits the vehicle parts more than the first search item is set to be enabled; and outputting the searched information on the vehicle parts; and in the process of searching for information on the vehicle parts, when an update of information on the identified vehicle part satisfies a search item change condition, searching for information on the identified vehicle part using search conditions in which the first search item of the first search item and the second search item is set to be enabled. [Effects of the Invention]

[0010] The information processing device, information processing method, and information processing program of the present invention have the effect of making it possible to easily search for appropriate vehicle part information as needed. [Brief explanation of the drawings]

[0012] Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

[0013] <Outline of the information processing system> As shown in Figures 1 to 3, the information processing system S is mainly composed of an information processing device 1 that stores "vehicle parts" used in vehicles and performs information processing on information about specific vehicle parts, a first user terminal 100 that is used by a "parts provider," a second user terminal 200 that is used by a "parts user," and a third user terminal 300 that is used by a "parts demander," each of which is connected to the information processing device 1 via a network. Specifically, the information processing device 1 is a management server that provides information (stock information) on "vehicle parts" that are trade targets via a network and supports the distribution of vehicle parts. In this embodiment, the information processing device 1 is described as a device that provides information on vehicle parts and supports the distribution of vehicle parts, but the application is not limited to this. It can also be used as a device that searches for information on vehicle parts and outputs the information on the searched vehicle parts.

[0014] Here, "vehicle parts" are parts used in vehicles and are classified by part type. Part types include "first part types" classified by vehicle parts (structural parts), etc., and "second part types" classified by the distributor (sales route), quality, etc. of the vehicle parts. "First part type" is identification information such as part code, part name, part shape, part dimensions, part model year, part grade, part image, etc. "Second part type" is identification information such as genuine part, second genuine part, high-quality part, second-hand part, compatible part, etc. "Genuine parts" are parts officially sold by vehicle manufacturers. "Second-genuine parts" are parts officially sold by parts manufacturers. "Quality parts" are identical to genuine parts, but are not sold by vehicle manufacturers, but by parts manufacturers (manufacturers different from the official parts manufacturers mentioned above). Quality parts are parts that differ from genuine parts only in model number. "Used parts" are parts removed from used vehicles (used vehicles, vehicles, vehicles to be scrapped) that have been repaired, inspected, etc. so that they can be sold. "Compatible parts" are parts that are compatible with multiple vehicle models, regardless of whether they are new or used.

[0015] A "parts provider" is, for example, a parts manufacturer (genuine parts manufacturer, high-quality parts manufacturer), a used parts producer, or the like, who provides vehicle parts. The parts provider accesses the database (inventory database) of the information processing device 1 and registers the vehicle parts as products. The parts provider is also called a parts producer, and is the supplier of parts to the parts user. The used parts producer checks the condition of the received used vehicles, and if there are any resalable used parts, dismantles them in accordance with the Recycling Law. During the dismantling process, the used parts are removed and their quality is checked. The used parts are then registered as products in the database of the information processing device 1.

[0016] A "parts user" is a parts distributor, such as a parts dealer, wholesaler, or parts retailer, who purchases necessary vehicle parts and sells them to part consumers. The parts user accesses the database of the information processing device 1, checks the inventory status of the vehicle parts to be purchased, and if there are vehicle parts that meet the desired purchasing conditions, checks the condition of the vehicle parts, negotiates the purchasing conditions, and purchases the vehicle parts.

[0017] "Parts consumers" are businesses such as repair shops, body shops, gas stations, and leasing / rental companies that purchase vehicle parts sold by parts users. Parts consumers request vehicle parts to purchase, and if there are vehicle parts that meet their desired purchasing conditions, they negotiate the purchase conditions and purchase the vehicle parts. Vehicle owners then use the vehicle parts to repair or replace parts in their vehicles. It can also be said that parts consumers sell vehicle parts to vehicle owners.

[0018] The information processing device 1 has a database (DB) including a memory unit 10 that stores vehicle type information and part type information, an inventory information memory unit 11 that stores vehicle part information (inventory information), and a history memory unit 12 that stores vehicle part usage history information for each part supplier, part user, and part demander. The information processing device 1 may be provided with a database for managing the above-mentioned "vehicle part information," "information about vehicle parts," "usage history information," etc., or may be configured to acquire the latest information from an external management server that manages the above-mentioned "vehicle part information," "information about vehicle parts," "usage history information," etc., at any time and temporarily store the information.

[0019] The information processing device 1 executes information processing and provides software services to a first user terminal 100, a second user terminal 200, and a third user terminal 300 connected via a network. In detail, the information processing device 1 provides a software service for operating and managing a vehicle parts buying and selling market to a first user terminal 100 (parts provider), a second user terminal 200 (parts user), and a third user terminal 300 (parts demander). Specifically, it is as follows:

[0020] The information processing device 1 identifies users who use terminals such as the first user terminal 100, the second user terminal 200, and the third user terminal 300. Then, the information processing device 1 accepts input or selection of "vehicle part information (part type information)" and "information related to vehicle parts (information on supply conditions, information on trade promotion, etc.)" through user operation from the user-identified first user terminal 100 (parts provider), and performs supply registration of new vehicle parts. The information processing device 1 also accepts input or selection of "information related to vehicle parts" through user operation, and updates registered vehicle parts.

[0021] The information processing device 1 accepts input or selection of "vehicle type information" and "part type information" by user operation from the user-identified second user terminal 200 (parts user), and identifies the vehicle parts. Then, it searches for information (inventory information) of the vehicle parts to be purchased using search conditions based on search items set (preferred settings) for each user. Then, it outputs a list of the searched vehicle parts to the second user terminal 200. As will be described in detail later, when a parts provider updates information about the vehicle parts and the update satisfies the search item change conditions, the information processing device 1 can perform a search using search conditions that change the search items set by the user. For example, it can search for information about vehicle parts provided by a new parts provider, or search for information about vehicle parts for which the parts provider has provided information about sales promotions, and output the information about the vehicle parts. More specifically, the information processing device 1 accepts a request for a purchase (quote) from the user-identified third user terminal 300 (parts consumer), and notifies the second user terminal 200 (parts user) of information on the vehicle parts that the user wishes to purchase. Then, as described above, it searches for information on vehicle parts to be purchased using search conditions for which search items are set for each user, and outputs the search results. Then, it accepts a selection of a vehicle part from the list information of vehicle parts operated by the user, and determines the information on the vehicle parts to be notified to the parts consumer. In other words, the information processing device 1 provides the second user terminal 200 (parts user) with information (purchase information) about vehicle parts provided by the first user terminal 100 (parts provider), giving the second user terminal 200 an opportunity to purchase vehicle parts from the part provider. Also, the information processing device 1 outputs information (purchase request information) about vehicle parts requested by a third user terminal (parts demander) to the second user terminal 200, giving the second user terminal 200 an opportunity to sell the purchased vehicle parts (vehicle parts to be purchased) to the part demander.

[0022] The information processing device 1 accepts an input or selection of "information on vehicle parts required for vehicle maintenance (parts type information)" from the user-identified third user terminal 300 (parts demander) through a user operation, and outputs the information on the vehicle parts required for vehicle maintenance. Then, it accepts a purchase request (quote) through a user operation, and notifies the second user terminal 200 (parts user) of the information on the vehicle parts that the user wishes to purchase. Then, it outputs to the third user terminal 300 list information on vehicle parts that have been notified in response from each part user (parts seller). Then, it accepts a purchase selection of a vehicle part from the list information of vehicle parts through a user operation, and notifies the part user (parts seller) that sells the selected vehicle part. That is, the information processing device 1 provides information on vehicle parts necessary for vehicle maintenance to the third user terminal 300 (parts demander), and then accepts a purchase request for the necessary vehicle parts, provides list information of the vehicle parts notified by each second user terminal 200 (parts user), and gives an opportunity to purchase the most suitable vehicle part. The vehicle parts list information output to the second user terminal 200 (parts user) is different from the vehicle parts list information output to the third user terminal 300 (parts demander). For example, the former includes information on vehicle parts for each part provider (parts supplier) and information related to the vehicle parts, and the latter includes information on vehicle parts for each part user (parts seller) and information related to the vehicle parts.

[0023] The first user terminal 100 is an information terminal operated by the part provider, and specifically, is a computer such as a PC, a tablet terminal, or a smartphone. The first user terminal 100 is connected to the information processing device 1 via a network, and receives software services from the information processing device 1. Specifically, the first user terminal 100 can accept input or selection of "vehicle part type information" and "vehicle part-related information (information on purchasing conditions, etc.)" by user operation on the display screen (new part registration screen), and can register the supply of a new vehicle part. Also, registered vehicle parts can be updated. In other words, the "vehicle part registration data" shown in Fig. 2 can be sent to the information processing device 1, and the information on the vehicle part can be newly registered and updated as appropriate. Furthermore, when a registered vehicle part is selected (or not selected) by a part user, information on the selection factors of the part user ("feedback data" shown in Fig. 2) can be obtained.

[0024] The second user terminal 200 is an information terminal operated by a part user, and is a computer similar to the first user terminal 100, and receives software services from the information processing device 1. Specifically, the second user terminal 200 receives the "quotation request data" shown in FIG. 2 from the information processing device 1. Then, on the part identification screen shown in FIG. 5, the second user terminal 200 receives input or selection of "vehicle type information" and "part type information" by user operation to identify the vehicle parts to be searched for. Then, a search for vehicle parts to be purchased is performed using search conditions based on search items set (preferred settings) for each user, and the "vehicle parts purchase list data" shown in FIG. 3 is acquired. That is, the list information of the searched vehicle parts is displayed on the display screen (see the search result screen shown in FIG. 6). Then, the second user terminal 200 saves the list information of the vehicle parts, and receives a selection of a vehicle part from the list information of vehicle parts by user operation to determine the vehicle part desired to be purchased. Then, the second user terminal 200 requests the third user terminal 300 to notify the third user terminal 300 of the information of the determined vehicle parts. That is, the "quotation data" shown in FIG. 3 is transmitted. In addition, if a transaction is concluded (or is expected to be concluded) with the third user terminal 300 (parts demander), the second user terminal 200 purchases vehicle parts from the first user terminal 100 (parts provider) and sells the vehicle parts to the third user terminal 300.

[0025] The third user terminal 300 is an information terminal operated by a parts consumer, and is a computer similar to the first user terminal 100, and receives software services from the information processing device 1. Specifically, the third user terminal 300 accepts an input or selection of "information on vehicle parts required for vehicle maintenance (parts type information)" operated by the user, and displays the information on the vehicle parts required for vehicle maintenance on the display screen. Then, the third user terminal 300 requests a purchase request (quote) for the vehicle parts operated by the user from the information processing device 1. In other words, it transmits "quote request data" shown in FIG. 3. Then, it accepts list information (quote list information) of vehicle parts notified in response from each parts user (parts seller) from the information processing device 1, and displays the quote list information for the vehicle parts on the display screen. In other words, it acquires and displays the "vehicle parts quote list data" shown in FIG. 3 (see quote result screen shown in FIG. 9). Then, it accepts a purchase selection of a vehicle part from the list information of vehicle parts operated by the user, and notifies the seller (parts user) that sells the vehicle parts of the purchase request. When a transaction is concluded with the second user terminal 200 (parts user), the third user terminal 300 (parts demander) purchases the vehicle parts from the second user terminal 200.

[0026] As described above, the information processing device 1 specifies vehicle parts to be searched for by the second user terminal 200 (parts user), and searches for information on the vehicle parts using search conditions for which search items have been enabled for each user. When searching for information on the vehicle part, if the information on the identified vehicle part has been updated and the update satisfies the change condition for the search item, the information processing device 1 searches for information on the vehicle part using search conditions that have changed the validity setting of the above search item. In other words, by performing a search using search conditions based on search items that have been "preferentially set" in advance, the parts user can have vehicle parts that are superior to the parts user displayed in the search results, but it is also possible to have vehicle parts that are not extracted using search conditions based on the above search items (superior vehicle parts that the parts user is not aware of) displayed in the search results. "Best settings" are search item settings that allow parts users to extract the vehicle parts they want to display in search results. Search items are created based on vehicle part information (part type information) and other information about the vehicle part, and are items that users can enable or disable. The above search process allows parts users to obtain opportunities to purchase and sell high-quality vehicle parts that they are not aware of. Furthermore, they can review the search items in the "Quality Settings" so that newly discovered vehicle parts continue to appear in the search results. For example, if they want to continue handling vehicle parts from a new parts manufacturer, they can change the "Quality Settings" so that the new parts manufacturer appears in the search results.

[0027] In the above, the information processing device 1 performs information processing (search, output processing) regarding vehicle part transactions between the first user terminal 100 (parts provider), the second user terminal 200 (parts user), and the third user terminal 300 (parts demander), but the "supplier," "seller," and "sales destination" of the vehicle parts are not limited to those in the above embodiment. For example, the information processing device 1 may process information regarding a transaction of vehicle parts between second user terminals 200 (parts users). In this case, the first parts user becomes the "seller" and the second parts user becomes the "seller." Alternatively, the information processing device 1 may process information regarding a transaction of vehicle parts between a third user terminal 300 (parts demander) and a vehicle owner. In this case, the second user terminal 200 (parts user) becomes the "supplier," the third user terminal 300 becomes the "seller" that purchases from the supplier, and the vehicle owner becomes the "sales destination." Alternatively, the information processing device 1 may process information relating to a transaction of vehicle parts between the first user terminal 100 (parts provider) and the third user terminal 300 (parts demander). In this case, the first user terminal 100 is the "purchasing source" and the "selling source," and the third user terminal 300 is the "selling destination."

[0028] <Hardware configuration of information processing system> 2, the information processing device 1 is a computer including a CPU as a data arithmetic and control processing device (processor), a ROM, a RAM, and an HDD (SSD) as storage devices (storage unit, memory), and a communication IF for transmitting and receiving information data via the Internet. The information processing performed in the information processing device 1 is specifically performed by the processor. In addition to a main program that performs the functions necessary for a computer, the storage device of the information processing device 1 also stores an information processing program, and the functions of the information processing device 1 are realized by executing these programs by the CPU. The first user terminal 100, the second user terminal 200, and the third user terminal 300 are also computers with similar hardware configurations.

[0029] <Functions of the information processing system> As shown in FIG. 4, from a functional perspective, the information processing device 1 mainly comprises a memory unit 10 that stores various programs and various data such as “vehicle type information,” “part type information,” and “search item information,” an inventory information memory unit 11 that stores “parts inventory information,” a history memory unit 12 that stores “usage history information,” a communication unit 13, a part update unit 14, an identification unit 15, a part identification unit 16, a search unit 17, an output unit 18, a selection unit 19, a reception unit 20, and an information provision unit 21. These are composed of a CPU, ROM, RAM, HDD, communication interface, various programs, etc.

[0030] Regarding the first user terminal 100 from a functional perspective, its main components are a memory unit that stores various programs and various data, a communication unit that sends and receives various data to and from the information processing device 1, a display unit that displays information on vehicle parts transactions provided by the information processing device 1 on a screen, and an operation execution unit that accepts user operation input and executes operation processing. Similarly, the second user terminal 200 and the third user terminal 300 each include a storage unit, a communication unit, a display unit, and an operation execution unit as main components.

[0031] The functions of the information processing device 1 will be described in detail below. First, various pieces of information (data) stored in the storage unit 10, the inventory information storage unit 11, and the history storage unit 12 will be described. In this embodiment, the information processing device 1 is configured to include the storage unit 10, inventory information storage unit 11, and history storage unit 12, but this is merely an example, and the storage unit 10, inventory information storage unit 11, and history storage unit 12 may also be realized in an external storage device provided outside the information processing device 1. In this case, it is preferable that the information processing device 1 and the external storage device are connected via a communication path.

[0032] <<Various information (data)>> "Vehicle type information" is information that identifies the type of vehicle. Specifically, this information includes vehicle inspection certificate information, vehicle registration number, VIN code (individual identification number), model name, vehicle name, vehicle shape, vehicle dimensions, vehicle category, model, year, grade, engine displacement, fuel, and vehicle image. "Vehicle type" refers to a type of vehicle classified according to its intended use, such as a passenger car, a small freight vehicle, or a light four-wheeled passenger car. "Body shape" refers to a type of vehicle classified by body type, such as box type, convertible top type, station wagon, etc. By referring to this "vehicle type information," the information processing device 1 can identify the vehicle type. Furthermore, the information processing device 1 stores vehicle parts for each vehicle type, and by identifying the vehicle type, it can specify the vehicle parts (vehicle part group) corresponding to the identified vehicle type.

[0033] "Part type information" is information that identifies the type of vehicle part. Specifically, as described above, there is "first part type information" that is classified by the structural part of the vehicle, etc., and "second part type information" that is classified by the distributor (sales route) of the vehicle part, etc. The "first part type" is identification information such as a part code, a part name, a part shape, a part size, a part model year, a part grade, and a part image. The "second part type" is identification information such as genuine parts, second genuine parts, high-quality parts, second-hand parts, compatible parts, etc. By referring to this "part type information," the information processing device 1 can identify the first part type and the second part type of the vehicle parts that make up the vehicle. The storage unit 10 stores vehicle parts used in vehicles for each vehicle type based on "vehicle type information" and "part type information."

[0034] "Search item information" is information on the set items of search conditions when searching for a specific vehicle part. The information processing device 1 searches for vehicle parts using search conditions based on search items that are set to be valid from among the search item group. The search item information includes a "first search item" that searches for vehicle parts based on information about the part type of the vehicle part (part type information), and a "second search item" that is different from the first search item and that limits the vehicle parts more than the first search item. Hereinafter, the "first search item" will also be referred to as the first search item, and the "second search item" will also be referred to as the second search item.

[0035] The "first search item" is a search item for identifying the type of vehicle part. Specifically, it is a search item (list of search items) based on the above-mentioned "first part type" and "second part type." The "second search item" is a search item that further limits (narrows) the vehicle parts based on information on purchasing conditions, information on desired sales conditions, etc. Note that a search item that further limits the vehicle parts based on information on the required conditions of the parts consumer may also be included. Specifically, search items based on "purchasing conditions (purchasing status)" include purchase amount, the parts user's expected profit margin (expected gross profit), whether or not parts are in stock, the number of parts in stock for each vehicle part, purchasing speed, etc. Note that purchasing conditions are purchasing conditions set by the parts user, but can also be considered supply conditions set by the parts provider (conditions based on supply conditions). In addition, search items based on "desired sales conditions" include sales profit margin (gross sales profit), delivery speed (number of days required for delivery), return rate in past sales transactions (percentage of returns due to deformation, damage, etc.) etc. Desired sales conditions are the sales conditions desired by parts users in relation to parts demanders. The search items based on the "requirements of the parts consumer" include, for example, the desired purchase price, the desired purchase delivery date, and the requirements for the purchase.

[0036] By referring to the "search item information," the information processing device 1 can search for information on vehicle parts using search conditions based on search items that have been set as valid or invalid (preferred settings) for each user. That is, the information processing device 1 performs a search for each vehicle part using search conditions based on the "first search item" and the "second search item."Then, it outputs a list of the searched vehicle parts. For example, a parts user can search for vehicle parts to sell to a parts consumer based on the parts provider's "purchase condition information" for each vehicle part and the parts consumer's "desired sales condition information," and check the search results. The "search item information" is updated when a setting change is made based on a user operation, or when a search item change condition is met and a vehicle part extracted using the changed search item is selected.

[0037] "Parts inventory information" is inventory information for vehicle parts that are subject to purchase and sale. The parts inventory information is stored in association with at least a vehicle part ID that identifies the vehicle part, a quantity, and a provider ID that identifies the part provider. In addition, it is also possible to associate information such as a vehicle model ID (available vehicle model ID) that identifies the vehicle model for which the vehicle part can be used, and the registration date of the vehicle part. That is, the parts inventory information is information in which a vehicle part ID, registration date, quantity, part type, vehicle type, and part provider ID are associated with each vehicle part. The "Parts Inventory Information" includes information on all vehicle parts that are subject to trading, and is updated in real time as new vehicle parts are registered and existing vehicle parts are traded.

[0038] The parts inventory information is updated from time to time by receiving information on new vehicle parts to be bought and sold (vehicle parts registration data) from the first user terminal 100, and the information on all vehicle parts is centrally managed and stored in a state where it can be uniquely identified. The parts inventory information is also updated as needed by receiving information about vehicle parts from the first user terminal 100. "Information about vehicle parts" refers to information provided by parts providers (information useful to part users), such as sales promotion information (campaign information such as discount information and short delivery information). By referring to the above "parts inventory information," the information processing device 1 can output list information of vehicle parts as a search result for specific vehicle parts to the second user terminal 200 (parts user), as shown in Figures 6 to 8.

[0039] "Usage history information" is data that indicates the usage history of a vehicle part by a part user. This usage history data includes a user ID that identifies the part user, information about the vehicle part selected from the vehicle part list information searched by the part user, and information about the vehicle part that is associated with each other. Specifically, the information associates the user ID, vehicle part ID, part selection date, part quantity, part type, and vehicle type. Note that a provider ID that identifies the part provider who provided the vehicle part may also be associated with a consumer ID that identifies a part consumer who wishes to purchase the vehicle part. The usage history information also includes information on a list of vehicle parts searched by the part user. The usage history information also includes inventory information for each vehicle part held by the parts user, information regarding transactions with the parts provider, and information regarding transactions with the parts consumer. The inventory information may be input and updated by the parts user, or may be estimated based on the parts user's past search information and transaction information. The usage history information is not limited to that of part users, but may also include usage history information of part providers and part consumers.

[0040] By referring to the "usage history information," the information processing device 1 can perform a parts search not only when a parts search is performed by a user (parts user) but also when it is expected that the user will need vehicle parts, and output (automatically output) a list of searched vehicle parts. In addition, by referring to the "usage history information," the information processing device 1 may suggest to the user that the user change the settings of the search items in the search conditions. Information on vehicle parts recommended based on the usage history information may be output with priority.

[0041] <<Registration and renewal of vehicle parts>> The communication unit 13 acquires "vehicle part registration data" from the first user terminal 100 (parts provider) as information on vehicle parts to be newly traded. The parts update unit 14 updates the parts inventory information based on the "vehicle parts registration data." Specifically, the part update unit 14 accepts input or selection of "vehicle part information (part type information)" and "vehicle part information (supply condition information)" through user operation from the first user terminal 100, and registers the supply of a new vehicle part. Furthermore, the part update unit 14 accepts input or selection of "information about vehicle parts" by user operation for registered vehicle parts, and updates the information about the registered vehicle parts. "Information about vehicle parts" is information provided by the parts provider as described above, such as information about sales promotions.

[0042] Here, "updating information about vehicle parts" refers to updating information about vehicle parts stored in the storage unit 10 (inventory information storage unit 11), specifically, updating with provision information about vehicle parts provided by parts providers. The provision information about vehicle parts includes information about newly registered vehicle parts, information about vehicle parts, and information about already registered vehicle parts. The "update of information about vehicle parts" corresponds to the "conditions for changing search items" described later.

[0043] <<Identifying vehicle parts>> The identification unit 15 receives an input or selection of "vehicle type information" through a user operation from the second user terminal 200, and identifies the vehicle type of the vehicle. The part identification unit 16 identifies the vehicle parts (vehicle part group) stored in the storage unit 10 for the identified vehicle type. Furthermore, the part identification unit 16 accepts input or selection of "part type information" by user operation from the second user terminal 200, and identifies the vehicle parts to be searched for. Specifically, it is as follows:

[0044] The identification unit 15 receives "vehicle type information" input by a user operation from the second user terminal 200 via the "part identification screen" shown in FIG. A selection screen for identifying the vehicle type is displayed in the upper portion of the "parts identification screen" shown in Fig. 5. For example, vehicle type information such as the vehicle model name, model type, chassis number, year, grade, engine type, displacement, fuel, color, and trim is displayed. It can be seen that information such as the vehicle model name "AA-Wagon," model type "AA-**," chassis number "MH**," year "2002-2007," grade "**," engine model "**," displacement "6600," and fuel "gasoline" has been selected by user operation. The identification unit 15 receives the vehicle type information and identifies the vehicle type. Once the vehicle type has been identified, a list of vehicle parts (vehicle part groups) associated with the identified vehicle type is displayed in the lower part of the "part identification screen" shown in Fig. 5. Fig. 5 displays a list of vehicle parts classified by part codes.

[0045] The part identification unit 16 identifies a vehicle part group for the identified vehicle type. 5, the "Parts Identification Screen" shows that the "Parts Code" tab is selected, and that the "Parts Code List" displays a list of part code names in the order of the part codes. In other words, it shows that the vehicle parts identified by the parts identification unit 16 are displayed. The "parts code" is a code that defines the compatibility between vehicle parts.

[0046] The part identification unit 16 further receives input or selection of "part type information" through a user operation from the second user terminal 200, and identifies the vehicle part to be searched for. 5, it can be seen that the vehicle part with part code "12" and part code name "oil element" and the vehicle part with part code "14" and part code name "clean filter" have been selected from the group of vehicle parts displayed in the "part code list" (selected items are checked). In other words, it can be seen that the vehicle parts have been identified by the part identification unit 16. The part identification unit 16 may select multiple vehicle parts to be searched for, or may select one vehicle part. Note that by entering a "part code name," it is possible to narrow down the vehicle parts displayed in the "part code list." The part identification unit 16 accepts the execution of the "decision button" by the user operation and executes a search for the identified vehicle part.

[0047] In the above example, the vehicle parts to be searched are identified based on the "parts code," but vehicle parts may also be identified by a part type other than the "parts code." For example, vehicle parts may be identified based on a "vehicle parts ID" that identifies the vehicle part and is stored in association with the vehicle type. Alternatively, vehicle parts may be identified based on a "genuine parts ID" that indicates the part number of the genuine part. In this way, by identifying vehicle parts based on "parts codes" and searching for each vehicle part, it is possible to compare related vehicle part numbers, prices, stock, supplier information, etc.

[0048] <<Search for vehicle parts>> The search unit 17 searches for information on vehicle parts using search conditions in which at least one of a "first search item" that searches for vehicle parts based on information about the part type of the identified vehicle part, and a "second search item" that is different from the first search item and limits vehicle parts more than the first search item, is set to be active. The output unit 18 outputs information on the vehicle parts (list information on the vehicle parts) searched by the search unit 17. The present embodiment is specifically described below.

[0049] The search unit 17 accepts execution of the "decide button" by user operation from the second user terminal 200, and executes a search for the identified vehicle part. Specifically, the search unit 17 searches for information on the identified vehicle part using search conditions in which the "first search item" and the "second search item" are set to valid. The search conditions at this time are the "best settings" search conditions set by the user as search items. This allows information on identified vehicle parts to be searched for using search criteria based on the "first search item" that identifies the first part type and the second part type, and the "second search item" that further limits the vehicle parts based on information on purchasing conditions and desired sales conditions.

[0050] In the above search process (first search process), when the "search item change condition" is satisfied when searching for vehicle parts, the search unit 17 searches for information on the identified vehicle parts using the search condition in which the "first search item" is set to be valid, out of the "first search item" and the "second search item." In this case, the search range is broadened compared to the above search process to search for information on the identified vehicle parts (also referred to as second search process). In other words, the setting (setting range) of the second search item among the first and second search items is not enabled (disabled), or the restriction on the setting range is relaxed, and information on the identified vehicle parts is searched for. Note that the setting of the search item for the second part type among the first search items may be changed (the setting of "genuine parts" may be changed to the setting of "genuine parts, second genuine parts, and high-quality parts"). This allows parts users to obtain opportunities to purchase and sell high-quality vehicle parts that they themselves are not aware of. Furthermore, they can review the search items in the "Quality Settings" so that newly discovered vehicle parts (vehicle part manufacturers) continue to appear in search results. For example, if they want to continue handling vehicle parts from a new parts manufacturer, they can change the "Quality Settings" so that the new parts manufacturer appears in search results.

[0051] In the second search process, in order to extract vehicle parts that are more beneficial to the part user, the search unit 17 may preferentially extract vehicle parts that satisfy reference values ​​(set reference values) of advantageous search items such as the user's profit margin (sales profit margin), purchasing speed, inventory quantity, second part type, etc., based on information on the search items set by the user and the user's usage history information. Alternatively, the search items (search elements) that are advantageous to the user may be weighted, and vehicle parts with a high evaluation value based on the weighting (evaluation value exceeding a predetermined threshold) may be preferentially extracted.

[0052] In the above-mentioned second search process, when the above-mentioned "search item change conditions" are met after a search for the identified vehicle part has been performed in the past, the search unit 17 may perform the second search process at the timing when the next search for the identified vehicle part is performed. Alternatively, the search unit 17 may search for vehicle parts when a request to execute a parts search is received from a user, and may also perform a second search process when the "search item change condition" is satisfied.

[0053] In addition to the first and second search processes described above, when the "search item change conditions" are met when searching for vehicle parts, the search unit 17 can also search for information on the identified vehicle parts using search conditions in which only the "second search item" is set to be valid (also referred to as the third search process). In this case, vehicle parts for which promotional information (discount information, short delivery information, and other campaign information) is provided by the parts provider can be more easily extracted. Alternatively, vehicle parts with high trading demand can be more easily extracted.

[0054] The "condition for changing the search item" is that information about the identified vehicle part has been updated. Specifically, this is "an update of information about the vehicle part" stored in the storage unit 10 (inventory information storage unit 11), which is "an update based on the provision information of the vehicle part" provided by the part provider. The provision information of the vehicle parts includes information on the newly registered specific vehicle parts, information on the specific vehicle parts, and information on the specific vehicle parts that have already been registered. For example, when a new parts provider (a parts provider not set as a preferred by the user) updates information about a specific vehicle part, the update satisfies the "condition for changing a search item." Alternatively, when a new or existing parts provider updates sales promotion information (campaign information) about a specific vehicle part, the update satisfies the "condition for changing a search item." In this case, the search results for vehicle parts will include information on vehicle parts updated by the part provider.

[0055] As described above, the "condition for changing the search item" is satisfied by updating the information on the identified vehicle part or updating the information related to the vehicle part. Then, the information on the vehicle part identified by the search condition based on the changed search item is output. In addition, when information on a vehicle part is updated that satisfies a certain number of search items (for example, does not satisfy only one search item) out of the multiple search items set by the user, it is considered to satisfy the ``search item change conditions,'' and the vehicle part may be searched for using the changed search items. This makes it easier to extract vehicle parts that are more beneficial to part users.

[0056] The output unit 18 outputs list information (purchase list information) of the vehicle parts searched by the above search process. Specifically, the output unit 18 outputs the "parts search screen" shown in FIGS. 6 to 8 to the display screen of the second user terminal 200. The upper part of the "Parts Search Screen" displays information for identifying the vehicle type, as in Fig. 5. The lower part of the "Parts Search Screen" displays a list of vehicle parts identified as search results by the search unit 17. The "vehicle parts list information" is associated with information such as part code, part number, genuine / quality, manufacturer code, manufacturer name, product name, special notes, and part type (other part type) as "part items." These part items correspond to, for example, a "first part type." Additionally, "part items" such as whether or not there is a premium setting, QTY, standard price, selling price rate, selling price unit, cost rate, unit price, gross profit margin, gross profit amount, customer gross profit margin (estimated), delivery date and time (estimated), return rate, stock availability, warehouse code, warehouse name, current inventory, minimum inventory quantity, maximum inventory quantity, new / recycled, supplier code, supplier name, purchase date and time (estimated), group code, product markup group code, and stratification information are also associated. These part items correspond to, for example, "second part types."

[0057] According to Figure 6, the vehicle parts identified by the user are displayed as a vehicle part with part code "12" and product name "oil element (oil filter)", and also as a vehicle part with part code "14" and product name "clean filter". In addition, vehicle parts with "Yes" and "No" are displayed regarding whether or not they have a preferred setting. From this, it can be seen that the search item change conditions were met in the above search process, and the search unit 17 performed a search (second search process) using search conditions in which the first search item was set to be valid. In other words, vehicle parts with "No" preferred setting correspond to vehicle parts extracted using search conditions that do not depend on the second search item. 7, information such as the gross profit margin (%), gross profit amount (yen), and delivery date and time (estimated) is displayed as information on the vehicle parts specified by the user. The vehicle part presented third from the top (provided by supplier "Manufacturer Z") is displayed with a gross profit margin of "33%," gross profit amount of "300 yen," and delivery date and time of "March 5th," indicating that more beneficial vehicle parts are being presented to the user. 8, information on the vehicle parts specified by the user, such as new / recycled and supplier name, is displayed. It can be seen that the first vehicle part displayed from the top (provided by manufacturer A) is a "recycled part," and the third vehicle part displayed (provided by manufacturer Z) is a "new part." As shown in FIG. 8, "Manufacturer A," "Manufacturer B," and "Manufacturer Z" are displayed as supplier names (parts providers). For example, for vehicle parts with "no" premium setting, it is assumed that the vehicle parts are provided by a new parts provider, "Manufacturer Z." It is also assumed that the vehicle parts have a high "gross profit margin (gross profit amount)," a fast "delivery date and time," and a low "return rate," making them useful to users.

[0058] In the above, when the "second search item" is set as a search condition that is valid, the search unit 17 searches for vehicle parts using at least the profit margin information. At this time, the output unit 18 can output the list information of the vehicle parts searched by the search unit 17 in descending order of profitability. For example, it is advisable to sort the vehicle parts in descending order of profitability by filtering. Furthermore, when the "second search item" is set as a search condition, the search unit 17 searches for vehicle parts using at least the information on delivery speed. At that time, the output unit 18 can output the list information of vehicle parts in descending order of delivery speed.

[0059] The selection unit 19 accepts, through a user operation, a selection of a predetermined vehicle part included in the vehicle part list information (purchase list information) output by the output unit 18, and determines the vehicle part. That is, the part provider can select a predetermined vehicle part from the specific vehicle part candidates found by the part search through the "parts search screen" shown in Fig. 6. The selection unit 19 determines the vehicle part selected by the second user terminal 200 (parts user) as the "vehicle part desired to be purchased." The communication unit 13 notifies the third user terminal 300 (parts demander) of information on the determined vehicle part. In other words, the communication unit 13 notifies the third user terminal 300 of quotation information (quotation data) for the vehicle part as a response to the quotation request from the third user terminal 300. When a plurality of vehicle parts are identified, the selection unit 19 selects a predetermined vehicle part for each vehicle part.

[0060] The history storage unit 12 stores the "vehicle parts list information" searched by the search unit 17 and output by the output unit 18. Specifically, the vehicle parts list information is stored as usage history information of the user. By saving the "vehicle parts list information" searched by the user, it is possible to grasp the information on vehicle parts that the user has previously searched for, information related to vehicle parts, and the search conditions (search items) for vehicle parts.

[0061] <<Change search items (change preferred settings)>> The search unit 17 searches for information on a specific vehicle part using the search criteria in which the "first search item" is set to be valid out of the "first search item" and "second search item" by the second search process. At this time, when a "predetermined vehicle part" included in the vehicle part list searched by the above search criteria is selected, the search unit 17 changes (changes the setting of) the "second search item" set by the user. When searching for information on the specific vehicle part through the first search process, the search unit 17 searches using search conditions that have been set to enable the "first search item" and the "second search item" that has been changed to a search item that includes the "specific vehicle part." For example, the "predetermined vehicle part" is a vehicle part that is not extracted by search criteria based on the preferred search item, and corresponds to a vehicle part provided by a new parts provider or a vehicle part for which information on sales promotion has been provided by an existing parts provider. When the user selects the "predetermined vehicle part," the user's preferred setting can be changed to give the user the opportunity to continue purchasing this "predetermined vehicle part." In other words, the "second search item" can be changed. For example, a new transaction can be established with a parts manufacturer with which the user has not had a business relationship. In other words, when the search unit 17 searches for information on vehicle parts using search conditions in which the "first search item" is set to be active, the output unit 18 outputs vehicle part list information, and the selection unit 19 selects a "predetermined vehicle part," it is determined whether the "predetermined vehicle part" is not extracted using search conditions in which the "first search item" and the "second search item" are set, but is instead extracted using search conditions in which only the "first search item" is set. Then, when it is determined that the "predetermined vehicle part" is extracted using search conditions in which only the "first search item" is set, the search unit 17 changes the setting of the predetermined "second search item." That is, the "second search item" is changed to a search item that includes the "predetermined vehicle part."

[0062] In addition, when the search unit 17 searches for information on a specific vehicle part using the second search process and selects a "specified vehicle part" included in the searched vehicle part list, it is assumed that the "specified vehicle part" is a vehicle part extracted using the search criteria that have been set. In this case, it is determined that the proposed vehicle parts are not beneficial to the user, and the search unit 17 does not change the user's preferred settings. In other words, when it is determined that the "specific vehicle part" selected by the selection unit 19 is not a part extracted using search conditions in which only the "first search item" is set, the search unit 17 does not change the setting of the "second search item" but continues to search for vehicle parts using the pre-set "first search item" and "second search item."

[0063] <<Part search execution trigger>> The search unit 17 executes a search not only when a search for a specific vehicle part is executed by a user operation, but also when the user is expected to need a vehicle part (when a search for a vehicle part is required).The output unit 18 can output (automatically output) a list of searched vehicle parts. The search unit 17 refers to the "usage history information" stored in the history storage unit 12, and executes a search at a time when the user is expected to need a vehicle part. The output unit 18 uses the search results obtained by the search unit 17 to output the vehicle parts corresponding to the “use history information” of the vehicle parts stored in the history storage unit 12 . Specifically, the following cases are envisaged:

[0064] The "first case" is when a parts user does not need to use a particular vehicle part immediately, but needs to replenish the parts user's inventory. For example, this occurs when the vehicle part is out of stock or the inventory number falls below a certain number. The "usage history information" includes inventory information for each vehicle part of the parts user. In this case, the part identification unit 16 determines that the part user's inventory needs to be replenished based on the "usage history information," and identifies the vehicle part that needs to be replenished. The search unit 17 searches for the vehicle parts identified by the part identification unit 16. Then, the output unit 18 outputs list information of the searched vehicle parts. In this way, vehicle parts (requiring inventory replenishment) corresponding to the "usage history information" of the vehicle parts can be identified, searched, and output. In addition, vehicle parts corresponding to the "usage history information" are assumed to include vehicle parts for which estimate requests (purchase requests) are expected based on past transaction information, and vehicle parts for which demand is expected based on transaction information including other vendors (vehicle parts for which the market price will rise). This allows a search to be performed when a specific vehicle part needs to be replenished, and a list of vehicle parts can be output, allowing the user to select and purchase the desired vehicle part.

[0065] The "second case" is a case where a parts user is likely to use a specific vehicle part in the future, for example, when a request for a quote (advance confirmation regarding purchase) for a vehicle part is received from a parts demander. In this case, the part identifying unit 16 is triggered by receiving "quotation request data" from the third user terminal 300 (parts demander) to identify the vehicle part for which a quotation has been requested. The search unit 17 searches for the vehicle parts identified by the part identification unit 16. Then, the output unit 18 outputs list information of the searched vehicle parts. This allows the user to select the desired vehicle part and notify the estimate data for the vehicle part.

[0066] The "third case" is when a parts user immediately uses a specific vehicle part, for example, when an order for a vehicle part or an order for work that uses a vehicle part is received from a parts consumer. In this case, the part specifying unit 16 is triggered by receiving "purchase request data (parts order)" from the third user terminal 300 (parts demander) to specify the vehicle part for which a purchase request has been made. The search unit 17 searches for the vehicle parts identified by the part identification unit 16. Then, the output unit 18 outputs list information of the searched vehicle parts. This allows the user to select the desired vehicle part and sell the vehicle part.

[0067] <<Automatic selection of searched parts>> The selection unit 19 accepts a selection of a specific vehicle part included in the searched "list information of vehicle parts" through user operation and selects the vehicle part, and also selects (automatically selects) a specific vehicle part from the "list information of vehicle parts" without user operation. That is, by referring to the "use history information" stored in the history storage unit 12, the selection unit 19 can select vehicle parts that are useful (or are determined to be useful) for the user. The "usage history information" includes purchase information and sales information for each vehicle part of the part user. Specifically, the following selection process (automatic selection process) is assumed.

[0068] The "first selection process" is a process of selecting a predetermined vehicle part based on the past delivery status of the parts user to the parts consumer. For example, when delivering vehicle parts to a parts consumer who purchases a lot of used parts, it is expected that used parts will be selected with priority over genuine parts or high-quality parts. In this case, the selection unit 19 selects vehicle parts that are recycled (used parts) in the part item "new / recycled" from the candidates in the vehicle parts list information based on the "usage history information." In addition, when there are multiple candidates for recycled (used) vehicle parts, the selection unit 19 may select from the candidates for recycled (used) vehicle parts the vehicle part with the highest profit margin (gross profit rate) or the vehicle part with the fastest delivery speed (delivery date and time, purchase date and time). This allows the system to automatically select the most suitable part based on the user's needs from the "vehicle parts list information." At this time, the system may accept confirmation of the user's operation and determine the selected vehicle part.

[0069] The "second selection process" is a process in which the parts user analyzes the information on which the estimate requested by the parts purchaser is based, and selects vehicle parts according to that information. The "information that forms the basis of an estimate" is, for example, information about the requested work when a vehicle owner requests a parts purchaser (such as a repair shop) to perform a specific maintenance work (work type). The parts identification unit 16 acquires work history information (usage history information) of the parts purchaser (third user terminal 300) and identifies the past selection history (purchase history) of vehicle parts based on the information. The search unit 17 then searches for vehicle parts using the same (similar) search item setting conditions based on the identified selection history. The selection unit 19 automatically selects the searched vehicle parts. The selection process may involve using analysis using artificial intelligence (AI) to select vehicle parts based on the analysis results. More specifically, for vehicle owners who prefer new parts, it is advisable to limit the selection to new parts (genuine parts, second-hand genuine parts, high-quality parts) rather than used parts, and further select vehicle parts based on information on purchasing conditions and desired sales conditions.

[0070] The "third selection process" is a process of selecting predetermined vehicle parts based on the sales policy of the parts user. For example, it is assumed that vehicle parts with high profit margins (gross profit rates) or vehicle parts with fast delivery speeds (delivery date and time, purchase date and time) are selected with priority. In this case, the selection unit 19 selects the vehicle part with the highest value in the part item "gross profit margin" from the candidates in the vehicle part list information based on the "usage history information." Alternatively, it selects the vehicle part with the earliest delivery date in the part item "delivery date and time (purchase date and time)."

[0071] <<Feedback function>> When a specific vehicle part included in the "list information of vehicle parts" output by the output unit 18 is selected, the receiving unit 20 receives "information regarding the selection factors" for the specific vehicle part selected by user selection. Then, the information providing unit 21 provides the "information relating to the selection factors" received by the receiving unit 20 to the external terminal (first user terminal 100). "Information regarding selection factors" is information indicating the selection factors selected by the second user terminal 200 (parts user) from among multiple vehicle part candidates. Specifically, it is the reason for selecting that vehicle part and the reason for not selecting other vehicle parts. For example, it may be that the selected vehicle part had the highest profit margin (purchase profit margin) or the fastest delivery speed. The information providing unit 21 provides "information related to the selection factors" to the part provider (first user terminal 100) that provided the vehicle part selected by the selecting unit 19. In other words, the information providing unit 21 transmits "feedback data" including the "information related to the selection factors" to the first user terminal 100. Furthermore, the information providing unit 21 provides "information on selection factors" to the part provider (first user terminal 100) that provided the vehicle part that was not selected by the selecting unit 19. In other words, the result based on the reason for the selection can be fed back to the part provider whose vehicle part was not selected. This feedback allows parts providers to understand the part sales situation of other companies and use this information in their future sales strategies.

[0072] The receiving unit 20 may also receive, from the first user terminal 100 (parts demander), "information on selection factors" used to select a specific vehicle part from among candidate vehicle parts notified by a plurality of second user terminals 200. In other words, this is "information on selection factors" when the parts demander requests an estimate for a vehicle part to be purchased and decides to have a specific parts user purchase the vehicle part from a plurality of candidate parts users. The information providing unit 21 provides the "information relating to the selection factors" received by the receiving unit 20 to an external terminal (second user terminal 200).

[0073] <Information processing method> Next, the processing of the information processing program (information processing method) executed in the information processing system S will be described with reference to FIGS. The program according to this embodiment is a program for realizing the above-mentioned communication unit 13, part update unit 14, identification unit 15, part identification unit 16, search unit 17, output unit 18, selection unit 19, reception unit 20, and information provision unit 21 as functional components of information processing device 1, which is equipped with storage unit 10, inventory information storage unit 11, and history storage unit 12 (memory). The CPU (processor) of information processing device 1 executes this information processing program. The memory unit 10 of the information processing device 1 stores "vehicle type information," "parts type information," and "search item information," the inventory information memory unit 11 stores "parts inventory information," and the history memory unit 12 stores "user usage history information."

[0074] In the processing flow of the information processing method, first, the communication unit 13 acquires "vehicle part registration data" as information on a new vehicle part from the first user terminal 100 (parts provider). Then, the part update unit 14 registers the new vehicle part based on the "vehicle part registration data" (step 1 (S1)). Furthermore, the communication unit 13 acquires information about the registered vehicle parts from the first user terminal 100. Then, the part update unit 14 updates the information about the registered vehicle parts (step 2). As described above, when a new vehicle part is provided by a parts provider or when sales promotion information for an existing vehicle part is updated, the parts update unit 14 updates the parts inventory information stored in the inventory information storage unit 11.

[0075] In step 3, the communication unit 13 receives a "vehicle part quotation request (quotation request data)" required for vehicle maintenance from the third user terminal 300 (parts purchaser). Specifically, the parts purchaser specifies the type of work required for vehicle maintenance (vehicle inspection, regular inspection, oil change, etc.). Then, the purchaser searches for the work content corresponding to the specified work type and the vehicle parts required for the work content. Then, the purchaser makes a "vehicle parts quotation request" to the second user terminal (parts user) through the information processing device 1. The parts purchaser designates, for example, a preset parts user and makes a "vehicle parts quotation request" to the parts user.

[0076] In step 4, the communication unit 13 transmits the "vehicle part quotation request" received from the third user terminal 300 to the second user terminal 200 (parts user). The parts user receives a "vehicle parts quotation request", checks the stock status of the vehicle parts to be quoted, and if the parts user does not have the vehicle parts in stock, purchases the vehicle parts through the information processing device 1.

[0077] In steps 5 to 9, the communication unit 13 accepts a request from the second user terminal 200 (parts user) to execute a search for a vehicle part (specific vehicle part) to be estimated, and the search unit 17 searches for the specific vehicle part. Specifically, in step 5, the identification unit 15 identifies the vehicle type of the vehicle based on the “vehicle type information” received from the second user terminal 200. Then, in step 6, the part identification unit 16 identifies a group of vehicle parts stored in the storage unit 10 for the identified vehicle type. At this time, the part identification unit 16 further accepts a selection of "part type information" by user operation from the second user terminal 200, and identifies the vehicle parts to be searched for. The vehicle type identification process and vehicle part identification process are performed through the "part identification screen" shown in FIG. 5 as described above.

[0078] In step 7, the search unit 17 determines whether or not the "conditions for changing search items" are met when searching for a specific vehicle part. When the "search item change conditions" are met (step 7: Yes), the process proceeds to step 8, where the search unit 17 searches for information on the identified vehicle part using the search conditions for which the setting of the "first search item" is enabled out of the "first search item" and "second search item." If the "search item change conditions" are not met (step 7: No), the process proceeds to step 9, where the search unit 17 searches for information on the identified vehicle part using the search conditions in which the "first search item" and "second search item" are set to valid.

[0079] The "condition for changing a search item" is that information about a specified vehicle part has been updated. For example, in step 1, when a vehicle part newly provided by the first user terminal 100 (parts provider) is a specific vehicle part, the condition for changing a search item is met. Alternatively, in step 2, when information about a specific vehicle part (such as sales promotion information) is updated by the first user terminal 100 (parts provider), the condition for changing a search item is met.

[0080] In step 10, the output unit 18 outputs the "vehicle parts list information (purchase list information)" searched by the search unit 17. Specifically, the output unit 18 outputs the "parts search screen" shown in Figs. 6 to 8 to the second user terminal 200.

[0081] In step 11, the selection unit 19 accepts a selection of a predetermined vehicle part included in the "vehicle part list information" from the second user terminal 200 (parts user) and selects (determines) the vehicle part. Specifically, the selection unit 19 determines the vehicle part selected by the second user terminal 200 as the "vehicle part desired to be purchased." The history storage unit 12 stores the "vehicle parts list information" searched by the user.

[0082] In step 12, the communication unit 13 notifies the third user terminal 300 (parts demander) of information on the vehicle parts selected by each second user terminal 200 (each part user). Then, in step 13, the communication unit 13 outputs the "vehicle part list information (quotation list information)" notified in response from each part user. Specifically, the communication unit 13 outputs the "Parts Estimate Result Screen" shown in FIG.

[0083] In step 14, the communication unit 13 accepts a selection (purchase selection) of a vehicle part from the "list information of vehicle parts" from the third user terminal 300 (parts demander), and determines the vehicle part to be purchased. Specifically, the third user terminal 300 (parts demander) determines the vehicle parts they wish to purchase from the "vehicle parts estimate list information" and makes a purchase request for the determined vehicle parts. The parts demander then creates a "work instruction" document that includes information on the work required for vehicle maintenance and information on the vehicle parts required for the work. The parts demander also creates a "vehicle maintenance estimate" for the vehicle owner.

[0084] In step 15, the communication unit 13 notifies the second user terminal 200 (parts user) that has been notified of the estimate for the vehicle part to be purchased that the vehicle part has been selected. The second user terminal 200 (parts user) that has received the notification purchases the vehicle parts and then sells the vehicle parts to the parts demander.

[0085] In step 16, the communication unit 13 notifies the first user terminal 100 (parts provider) that has registered the vehicle part to be purchased that the vehicle part has been selected. Upon receiving the notification, the first user terminal 100 (parts provider) prepares to supply the vehicle parts, and supplies the vehicle parts to the parts user.

[0086] In step 17, the history storage unit 12 stores the vehicle part usage history information for each of the first user terminal 100 (parts supplier), the second user terminal 200 (parts user), and the third user terminal 300 (parts demander).

[0087] In step 18, when a predetermined vehicle part included in the "Vehicle Parts Purchase List Information" shown in Figures 6 to 8 is selected, the receiving unit 20 receives "information related to selection factors" of the vehicle part selected by the user. Also, when a predetermined vehicle part included in the "Vehicle Parts Estimate List Information" shown in Figure 9 is selected, the receiving unit 20 receives "information related to selection factors" of the vehicle part selected by the user. Then, the information providing unit 21 provides the "information related to the selection factors" received by the receiving unit 20 to the external terminals (the first user terminal 100 and the second user terminal 200).

[0088] After going through the above steps S1 to S18, the processes of FIGS. 10, 11, and 12 are completed. The above information processing method makes it possible to easily search for appropriate vehicle part information as needed. For example, when a parts provider updates information about a vehicle part (registration information for the vehicle part, sales promotion information), a parts user can search for and check the updated vehicle part.
