Description

{CAR VALUATION AND REWARD SYSTEM USING COLLECTED AND ANALIZED CAR DATA THROUGH PLATFORM BASED ON BLOCK-CHAIN AND USED CAR DEALING SYSTEM USING THE SAME}

The present invention relates to a vehicle value assessment and compensation system based on vehicle data collected and analyzed through a blockchain-based platform and a used car transaction system using the same.

In particular, the present invention supports safe and efficient driving by measuring vehicle data such as real-time fuel efficiency and carbon emissions based on vehicle data that monitors the electrical and electronic operating status of the vehicle, and tokens given as compensation for this contribute to carbon neutrality and can also be effectively utilized for vehicle maintenance, automobile insurance, used car transactions, etc.

Blockchain is a technology that stores data based on cloud technology and P2P (Peer-to-Peer) distributed network technology.

A P2P distributed network consists of clients and nodes, and when a client generates a new transaction, the nodes share and execute the transaction through a distributed consensus process.

Nodes have a DB that stores a list of transactions, and the DB that stores the list of transactions is structured as a blockchain. The blockchain is structured in which blocks are linked in chronological order, and each block contains a list of transactions in a set order.

Transactions store a hash of the data to ensure the authenticity of the transaction, but do not store the data itself.

Therefore, if this blockchain technology is combined with data that analyzes real-time vehicle data and configured as a network for reducing carbon emissions, automobile insurance, and used car transactions, it will be a very useful technology.

In general, when buying and selling used cars, transactions are often made through used car dealers or dealers rather than through direct transactions between individuals. This is a situation where the market price is checked and traded using the offline used car market or the used car market price online is used as a reference price.

However, various information on used cars is used not only by dealers but also by various other places such as capital companies and repair shops, making it vulnerable to information leaks such as hacking. Recently, there has been an increase in cases of abuse such as manipulation of mileage and accident history.

In particular, although we are trying to ensure complete security by building a separate security server, this is a very contradictory situation and we are still vulnerable to information alteration and distortion due to hacking.

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

As illustrated in FIGS. 1 to 5, the vehicle value assessment and compensation system using vehicle data collected and analyzed through the blockchain-based platform of the present invention and the used car transaction system using the same include: a management server (1) that controls the entire system for vehicle value assessment and compensation and used car transaction using vehicle data; a vehicle owner or driver smartphone (100) that receives vehicle data in real time from the vehicle through an OBD2 (On-Board Diagnostics) interface; a vehicle data server (200) that receives and stores the vehicle data received by the smartphone (100) and manages it; a blockchain server (300) that maps the vehicle data stored and managed in the vehicle data server (200) to a blockchain network; an AI server (400) that diagnoses and predicts the vehicle condition based on the vehicle data, analyzes the vehicle value, and converts it into a vehicle price; a local government server (500) and a government server (550) that monitor carbon emissions based on the vehicle data; an automobile insurance server (600) that manages vehicle accident history information, etc. based on the vehicle data; and a used car transaction server between a buyer and a seller for used car transactions. It consists of a vehicle transaction server (700) that controls transaction operations.

The above automobile insurance server (600) may be networked with an automobile insurance company (650), and the used car transaction server (700) may be networked with a used car company (seller) (750).

The above management server (1) may be configured as a business model platform in which, as another embodiment, a vehicle owner or driver purchases an OBD2 scanner on an automobile transaction platform according to the present invention and registers the vehicle as a for-sale vehicle, and a certain transaction fee is received when the transaction is completed, and in connection therewith, a franchise fee for automobile repair shops and insurance companies may also be received as a fee.

In addition, it can be configured as a business model platform that can provide the rights to export and trade used cars overseas (such as in Southeast Asia) by linking with other platforms, and can also obtain commissions and franchise fees for maintenance, refueling, and insurance subscriptions by linking with repair shops, gas stations, and insurance companies.

The above maintenance may be performed after the maintenance shop is authenticated by the platform, as there may be cases where a clear authentication of the vehicle is required in P2P transactions, and a service may also be provided where the maintenance shop provides information on vehicle breakdowns and parts replacement to the vehicle owner or driver through the platform.

The vehicle value assessment and compensation system using vehicle data collected and analyzed through the blockchain-based platform configured as described above and the used car transaction system using the same, when vehicle data transmitted from a vehicle through an OBD2 interface is received by a smartphone (100), the smartphone (100) transmits the vehicle data to a vehicle data server (300).

The above vehicle data may include vehicle type, year, specifications, price, mileage, accident maintenance/history, vehicle and parts condition, vehicle price, insurance premium (vehicle mileage/condition), insurance premium calculation period, carbon emissions, parts usage rate, parts replacement cycle, coolant, brake oil, engine oil, engine RPM, vibration, sound, tire pressure, vehicle acceleration, average speed, abnormalities in safety equipment such as ABS and airbags, battery voltage, engine temperature, engine wear, tire pressure, and brake belt wear, but is not necessarily limited to these.

The AI server (400) analyzes and processes the above vehicle data based on deep learning to provide diagnostic information, and the blockchain server (300) provides the diagnostic information analyzed and processed by the AI server (400) to a smartphone (100), a local government server (500), an automobile insurance server (600), and a used car transaction server (700) through each node.

The AI server (400) collects usage information and status information of the engine, transmission, steering device, suspension device, safety device, etc., and continuously identifies flow information for the relevant parts. This analyzes basic statistical analysis and patterns of sensor information of the vehicle to check the response time and activity history of each sensor, and attempts additional data analysis using machine learning. Afterwards, the response time and response processing are checked based on time series analysis of the sensor data.

In addition, a predictive model is implemented to enable additional verification of sections where maintenance may be required. This confirms that the degree of vehicle aging varies depending on the vehicle's history and user management, and thus identifies sections with a high number of vehicle uses.

Data on equipment aging between vehicle device sections due to rapid acceleration, rapid deceleration, etc. is also analyzed and processed to analyze accumulated information on actual occurrences. Afterwards, additional analysis is conducted on the aging section based on accumulated information on the driver's long-term usage habits.

The above diagnostic information may include vehicle monitoring information, vehicle failure diagnosis information, and carbon reduction information as information transmitted to a smartphone (100), and the information processed in this way may be applied to automobile maintenance, automobile insurance, used car transactions, automobile parts sales, etc.

In addition, the carbon reduction amount information as the above diagnostic information can be used as compensation information for reducing carbon emissions, and the vehicle information provided through the smartphone can also be used as compensation information.

The above compensation may be implemented in the form of providing Stable Coins, and may be, for example, paid in Stable Coins for providing vehicle data, paid in Stable Coins equivalent to the current vehicle price determined by the AI server (400), paid in Stable Coins for reducing carbon emissions, etc.

The above Stable Coin can be converted into points when trading used cars and used for escrow and vehicle insurance premiums.

The present invention, configured in this way, also enables direct automobile transactions between sellers and buyers based on P2P blockchain. In other words, in the future, individual transactions between individuals are possible reliably based on blockchain vehicle data without the need for a used car dealer to intervene.

This operation can be performed in a system consisting of a vehicle owner, an insurance company, and an automobile manufacturer, where the vehicle owner provides his or her vehicle information, the insurance company provides accident history, etc., and the automobile manufacturer exchanges coins and points to enable vehicle transactions. The accident history may include the date and time of the accident, the location of the accident, the type of accident (the other vehicle number, if necessary), the details of the accident (brief description), the cost of repairs (parts, labor, painting), the details of the main repairs, and the name of the repair company (business registration number). However, it is not necessarily limited to these.

Vehicle information provided by the above owner may include, but is not limited to, mileage, accident maintenance/history, vehicle and parts condition data, vehicle price, insurance premium (vehicle mileage/condition), and insurance premium calculation period.

At this time, when trading used cars through P2P, capital can play a role in payment, lending, and escrow.

As illustrated in FIG. 6, vehicle information collection and analysis according to one embodiment of the present invention can be performed by a system comprised of an OBD2 interface (vehicle information collection device) (10), a monitoring device (20), and a blockchain-based app (platform) (30).

The OBD2 interface (10) is an international diagnostic standard for checking and controlling the electrical and electronic operation status of a vehicle, and is mainly intended for monitoring exhaust gas. In the present invention, an OBD2 device is used to collect vehicle data, and this device is purchased by the vehicle owner or driver and installed in a designated slot in the vehicle.

The OBD2 interface (10) recognizes the values defined by each brand of automobile and calculates real-time fuel efficiency and carbon emissions based on these values. The calculation results are used to guide safe and fuel-efficient driving.

In addition, we measure whether carbon emissions are reduced through safe driving and fuel efficiency improvement efforts, and provide compensation in the form of carbon tokens (Stable Coins).

The above carbon token is a blockchain-based digital currency that can be used like cash within the system of the present invention.

The monitoring device (20) monitors and displays the electrical and electronic operation status of the vehicle in real time using the OBD2 interface (10), and is used for fuel-efficient driving guide, consumables management, vehicle inspection requirement notification, etc., to support safe and fuel-efficient driving.

The monitoring device (20) is an electronic dashboard designed to simplify vehicle data collection using the OBD2 interface (10), thereby eliminating the need to connect to a smartphone app, thereby eliminating user inconvenience, and integrating aesthetic elements to provide real-time vehicle status information.

The monitoring device (20) is configured to be continuously connected to the OBD2 interface (10) via Bluetooth, and can be configured to display desired information on the screen by connecting to a smartphone when necessary. Such visual functions enable various in-vehicle presentations.

Unlike domestic OBD2 interface competitors that only provide the ability to view vehicle information through Android or iPhone apps, this invention provides a comprehensive platform. It is not a one-time service that can potentially distract the driver, but a platform that allows the user to manage the status of the vehicle from new vehicle to trade-in. This provides a much more holistic and user-friendly experience.

The app (platform) (30) collects and analyzes vehicle data from various angles to evaluate the vehicle value. When a user's vehicle is registered, the app (30) receives the entire vehicle history from the vehicle data server (CAR 365) and collects and analyzes data such as vehicle status, abnormal signs, and driving habits through the OBD2 interface (10). These data are organized using big data technology, and then a value evaluation is performed using artificial intelligence.

Through this vehicle value assessment, if fuel efficiency is improved and carbon emissions are reduced, carbon tokens, a blockchain-based digital currency, will be provided as a means of compensation, which can be used for vehicle maintenance, automobile insurance, and used car transactions.

This series of operation flows are implemented as operations in which, when a vehicle owner's vehicle is registered, the platform (30) receives the entire history of the vehicle from CAR 365, collects data such as vehicle status, abnormal signs, and driving habits through the OBD2 interface (10), analyzes the driver's driving habits and consumables management records to evaluate the driver's reliability, evaluates the vehicle's value based on the inspection records of CAR 365 and the vehicle's internal status data obtained through the OBD2 interface (10), and provides carbon tokens when fuel efficiency is improved and carbon emissions are reduced so that they can be used as a means of exchange for vehicle maintenance, automobile insurance, and used car transactions.

Hereinafter, the vehicle value assessment and compensation and used car transaction operations according to one embodiment of the present invention are explained by dividing them into value assessment, compensation, carbon emission reduction, insurance, used car transaction, etc. In the operation flow diagram, the interface server is the same server as the management server of Fig. 1.

Figure 7 is a flow chart of a vehicle value assessment operation using vehicle data collected and analyzed through a blockchain-based platform according to one embodiment of the present invention.

When the interface server transmits vehicle data to the AI server, the AI server analysis unit learns the vehicle status (learning model) based on the collected big data and analyzes it according to existing rules. In other words, the vehicle data is analyzed using the learning model and analysis.
