In the following figures, the same numbers or symbols are given to the same elements throughout the description of the embodiments.

[Basic concept/basic configuration]
FIG. 1 is a diagram for explaining an overview of a vehicle information management system 1 according to an embodiment of the present invention.

The vehicle information management system 1 includes a vehicle information management device 10 and a plurality of vehicles 20, and is a system in which the vehicle management device 10 acquires and manages vehicle information from the vehicles 20. The plurality of vehicles 20 are connected to the vehicle management device 10 via a wireless network such as 4G or Wi-Fi (registered trademark). Vehicle information managed by the vehicle information management system 1 is used by a client terminal 30 or the like connected to the vehicle management device 10 via a network.

The vehicle information management system 1 acquires vehicle information from a plurality of vehicles 20. Vehicle information includes unique information and vehicle operation information. Here, the unique information includes information for identifying the vehicle type, parts, or vehicle, such as a vehicle identification number, model number, vehicle body number, and engine model number. The operation information includes information indicating the operation status, such as speed, engine cooling water temperature, and engine rotation speed. Items such as vehicle identification number and engine speed are called management items.

When the management items of the vehicle information acquired from the vehicle 20 are only standard words (Case 1: the flow is shown by solid arrows in FIG. 1), the vehicle information management system 1 refers to the Nayoro dictionary database 121 and selects the management items. is determined to be a standard language, and the management items are recorded and managed in the vehicle information database 122 in association with the operation information.

In addition, when a management item of vehicle information includes a synonym (case 2: the flow is indicated by a broken line arrow in FIG. 1), the vehicle information management system 1 refers to the Nayoro dictionary database 121 to determine whether the management item is a synonym. It is determined that the management item exists, and after collating the management item with the standard word associated with the synonym, it is recorded in the vehicle information database 122 and managed.

Furthermore, the vehicle information management system 1 refers to the Nayoro dictionary database 121 when the vehicle information management item does not include either a standard word or a synonym (case 3: the flow is indicated by a long chain line arrow in FIG. 1). , determines that the management item is neither a standard language nor a synonym, performs natural language processing on the management item to name the management item with the standard language, and then records and manages the management item in the vehicle information database 122. . In this case, the vehicle information management system 1 performs natural language processing and records the management items whose names have been merged into standard words in the Nayoro dictionary database 121 in association with the standard words as synonyms.

In this way, when the vehicle information management item is not in a preset standard language, the vehicle information management system 1 uses the Nayoro dictionary database 121 or natural language processing to merge the management item with the standard language and Information management items can be unified and managed using standard language. Therefore, even if the management items of the vehicle information are different, the vehicle information can be acquired from the vehicle 20 and managed in an integrated manner.

[Functional configuration]
FIG. 2 is a diagram for explaining the functional configuration of the vehicle information management system 1 according to the embodiment of the present invention. The vehicle information management system 1 includes a vehicle 20 and a vehicle information management device 10 connected to the vehicle 20 via a wireless network. Although the vehicle information management device 1 is a cloud server in this embodiment, it may be an on-premises device.

(Functional configuration of vehicle)
The vehicle 20 includes an on-vehicle terminal 21 and a control device 22.

The in-vehicle terminal 21 is connected to a control device 22 via an in-vehicle network such as a CAN (Controller Area Network), and acquires vehicle information from the control device 22. Further, the in-vehicle terminal 21 is connected to the vehicle management device 10 via a wireless network, and transmits vehicle information to the vehicle management device 10.

The control device 22 is a device that performs various controls on the vehicle 20, and is also referred to as an ECU (Electronic Control Unit) 22 in this embodiment. The ECU 22 includes an OBD (On Board Diagnosis) 23.

A plurality of ECUs 22 are provided for each function of the vehicle 20, such as an engine ECU, a vehicle control ECU, and a brake ECU, and acquire operation information from various connected sensors under predetermined conditions and timing. For example, the operation information is "3000 rpm" of the "engine speed" that the engine ECU acquires from the engine speed sensor.

The OBD 23 detects vehicle malfunctions and stores them in a predetermined storage area of the ECU 22. Specifically, the OBD 23 determines whether or not the vehicle 20 is out of order under predetermined conditions based on the values of various sensors acquired by the ECU 22, and generates an identification code according to the details of the fault. Remember.

(Functional configuration of vehicle information management device)
The vehicle information management device 10 includes a communication section 11 that communicates with the in-vehicle terminal 21 of the vehicle 20 via a wireless network, a storage section 12, an acquisition section 13, and a nayoro processing section 14.

The storage unit 12 includes a Nayoro dictionary database 121 (hereinafter, the database may be referred to as DB) used for Nayoro processing, and a vehicle information database 122 that stores vehicle information acquired from the vehicle 20. In addition, since the vehicle information management device 10 is a cloud server in this embodiment, it is desirable that the storage unit 12 is constructed using cloud storage or a distributed ledger.

The acquisition unit 13 acquires vehicle information from the vehicle 20 via the communication unit 11 . As described above, the vehicle information includes at least management items and operation information associated with the management items, and may also include acquisition date and time of operation information, acquisition location information of operation information, and the like.

The nayoro processing unit 14 performs nayoro processing to aggregate the management items of the vehicle information acquired by the acquisition unit 13. Specifically, first, the Nayoro processing unit 14 extracts management items from the vehicle information acquired by the acquisition unit 13, and collates the extracted management items (hereinafter referred to as extracted management items in this specification) with the Nayoro dictionary DB 121. do.

FIG. 3 is a diagram schematically showing the Nayoro dictionary DB 121 according to the embodiment of the present invention. In this embodiment, the Nayoro dictionary DB 121 stores standard words and synonyms in association with each other. Here, the standard language is a term that is used as a standard for management items of operation information, and is a term that is aggregated by Nayoro processing. A synonym is a term that has a different form from a standard word but has the same meaning. Standard words and synonyms in the Nayoro dictionary DB 121 are used in a preset state, and then synonyms are added by natural language processing to be described later.

Returning to FIG. 2, as a result of comparing the extracted management item with the Nayoro dictionary DB 121, if the extracted management item matches the standard language, the Nayoro processing unit 14 ends the Nayoro processing. On the other hand, as a result of comparing the extraction management item with the Nayoro dictionary DB 121, if the extraction management item matches a synonym, the Nayoro processing unit 14 performs Nayoro processing to change the extraction management item to a standard word associated with the synonym. I do.

Furthermore, as a result of comparing the extraction management item with the Nayoro dictionary DB 121, if the extraction management item does not match with either standard words or synonyms, the Nayoro processing unit 14 executes natural language processing to update the extraction management item. Performs Nayoro processing to change to standard language.

Specifically, the Nayoro processing unit 14 performs morphological analysis on the extracted management items, divides them into words, and determines the part of speech. For example, if the management item is "traveling speed", when morphological analysis is performed, it will be decomposed into "driving" (noun) and "speed" (noun). Next, the Nayoro processing unit 14 performs syntax analysis on the words that have been decomposed into the extracted management items, and analyzes relationships between words, such as relationships such as modification and being modified.

The Nayoro processing unit 14 then performs semantic analysis on the parsed words to create meaningful words. Specifically, the Nayoro processing unit 14 combines the parsed words to create a plurality of phrases. Then, using a pre-recorded collection of example sentences, a sentence example that matches the created phrase with the word and the relationship between the words is searched, and if the phrase can be searched, it is determined that the phrase is meaningful. On the other hand, if it cannot be determined that the word is a meaningful word or phrase, the Nayoro process is ended.

Here, it is preferable that the collection of sentence examples includes many sentence examples that include words used in vehicle information management items, and preferably includes materials related to failure diagnosis devices of each vehicle manufacturer, service manuals, and the like.

The Nayoro processing unit 14 collates the words obtained through natural language analysis with the Nayoro dictionary DB 121. As a result of comparing the word with the Nayoro dictionary DB 121, the Nayoro processing unit 14 associates the word with a standard word if the word matches a standard word, and associates the word with a matching synonym if the word matches a synonym. Nayoro processing is performed to change words to standard Japanese. Then, the Nayoro processing unit 14 adds the extraction management item that is the generation source of the phrase that has been Nayoro-processed into a standard word to the synonyms, and updates the Nayoro dictionary DB 121.

Further, the Nayoro processing unit 14 aggregates units of operation information. Specifically, the Nayoro processing unit 14 performs a process of converting the unit of operation information into a standard unit when a standard unit is set in advance in association with a standard word in the Nayoro dictionary DB 121. For example, if the standard unit of engine rotation speed is "rpm" and the unit of the acquired operation information is "rev/sec", the unit of the acquired operation information is converted to "rpm". Also, if the standard unit of temperature is "Celsius (℃)" and the unit of the acquired operation information is "Fahrenheit", the unit of the acquired operation information is converted to "Celsius (℃)". .

The Nayoro processing unit 14 performs Nayoro processing and manages the management items summarized in standard language and the operation information associated with the management items in the vehicle information DB 122.

FIG. 4 is a diagram schematically showing the vehicle information DB 122 according to the embodiment of the present invention. In the present embodiment, the vehicle information DB 122 stores vehicle identification information for identifying the vehicle 20, management items of the vehicle information, operation information associated with the management items, and date and time of acquisition of the operation information in association with each other. By storing the acquisition date and time of the operation information in the vehicle information DB 122, the operation information can be organized in chronological order.

The functional configuration of the present system described above is just an example, and one functional block (database and functional processing unit) may be divided, or multiple functional blocks may be combined into one functional block. Each functional processing unit is stored in a storage device (storage unit) such as a ROM (Read Only Memory), flash memory, SSD (Solid State Drive), or hard disk by a CPU (Central Processing Unit) built into the device or terminal. This is realized by reading out a computer program (for example, core software or an application that causes the CPU to execute the various processes described above), and executing the computer program by the CPU. In other words, each functional processing unit reads and writes necessary data such as tables from a database (DB) stored in a storage device or a storage area in memory, and in some cases, This is realized by controlling hardware (for example, input/output devices, display devices, communication interface devices). Further, the database (DB) in the embodiment of the present invention may be a commercial database, but it also means a simple collection of tables and files, and the internal structure of the database itself does not matter.

Vehicle information processing of the vehicle information management system 1 according to the embodiment of the present invention will be described using FIG. 5. This process is executed by the vehicle information management device 10.

First, the acquisition unit 13 acquires vehicle information including management items and operation information associated with the management items from the vehicle 20 (S1). Next, the Nayoro processing unit 14 extracts the management items of the vehicle information acquired in S1, and collates the extracted management items with the Nayoro dictionary DB 121 (S2).

Next, if the synonym in the Nayoro dictionary DB 121 matches the extraction management item as a result of S2, the Nayoro processing unit 14 changes the extraction management item to the standard word associated with the synonym that matches the extraction management item. Nayoro processing is performed (S3). Note that if the standard words in the Nayoro dictionary DB 121 match the extracted management items, the Nayoro processing is not performed.

Next, as a result of S2, the Nayoro processing unit 14 determines whether there are any extraction management items that do not match any of the standard words and synonyms in the Nayoro dictionary DB 121 and for which the Nayoro processing of S3 could not be performed. That is, after S3, it is determined whether there is an extraction management item that is not a standard word. If there is an extraction management item that is not a standard language (YES), the Nayoro processing unit 14 advances the process to S5, whereas if there is only a standard language extraction management item (NO), the process advances to S9 (S4).

Next, the Nayoro processing unit 14 performs natural language processing on the extracted management items that are not standard words, and obtains phrases for the extracted management items (S5). Next, the Nayoro processing unit 14 compares the phrase acquired in S5 with the Nayoro dictionary DB 121, and if it matches a standard word or a synonym in the Nayoro dictionary DB 121, performs Nayoro processing to convert the phrase into a standard word ( S6).

Next, as a result of S6, the Nayoro processing unit 14 determines whether there is a word or phrase that does not match any of the standard words or synonyms in the Nayoro dictionary DB 121 and for which the Nayoro processing could not be performed in S6. Determine whether there is an extraction management item that is not a standard word after . If there is an extraction management item that is not a standard language (YES), the Nayoro processing unit 14 ends the process, whereas if there is only a standard language extraction management item (NO), the process proceeds to S8 (S7).

Next, the Nayoro processing unit 14 updates the Nayoro dictionary DB 121 by adding the extracted management items that were Nayoro-processed in S6 to synonyms (S8). Finally, the name processing unit 14 records the management items named in standard language and the operation information associated with the management items in the vehicle information DB 122 (S9).

As explained above, in the vehicle information management system 1, when a management item of vehicle information is not in a preset standard language, the management item is aggregated by using the Nayoro dictionary DB 121 or natural language processing. can do. Therefore, the vehicle information management system 1 can acquire vehicle information from the vehicle 20 and manage the acquired vehicle information in an integrated manner even if the management items of vehicle information are different.

As a result, clients such as transportation companies that own the vehicles 20, maintenance shops that maintain the vehicles 20, and leasing companies that lease the vehicles 20 can use unified vehicle information about the vehicles 20, so they can improve maintenance and value. It can be used for evaluation work.

In addition, in the vehicle information management system 1, if a management item that is neither a standard word nor a synonym in the Nayoro dictionary DB 121 is similar to a standard word or a synonym as a result of natural language analysis, the management item is transferred to the Nayoro dictionary. Add to synonyms of DB121. This makes it possible to improve the accuracy of Nayoro processing.

Note that in this embodiment, the storage unit 12 may include a vehicle master database that stores basic information about the vehicle 20. Specifically, the vehicle master DB stores vehicle identification information and vehicle attribute information such as the vehicle type, size, manufacturer name, model, and year of manufacture in association with each other. The vehicle master DB is set in advance for the vehicle 20 for which vehicle information is to be acquired, and by managing it together with the vehicle information DB 122, it is possible to centrally manage the information regarding the vehicle required by the client.
