Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an exhaust gas quality evaluation method,

The present invention relates to a method for evaluating the quality of a running vehicle from exhaust gas inspection information, and more particularly to a method for evaluating the quality of a running vehicle engine from an exhaust gas DB obtained from an exhaust gas inspection station.

Emissions management of automobiles is classified into production cars and exhaust gas inspection for vehicles.

Manufactured car exhaust gas inspection is applied to pre-operation vehicles manufactured by automobile manufacturers. Inspection is conducted by authorized facilities according to inspection facilities and standards to check whether exhaust gas regulations are met. As a result of the evaluation, the standard for the whole car is made.

On the other hand, the inspection of vehicle exhaust gas means the inspection of exhaust gas which is applied to automobiles that are marketed and operated in general. It is carried out by inspection facilities and specially designated inspection sites (for example, TSA and local inspection offices) , And it is judged that the vehicle is unsuitable for driving through exhaust gas inspection.

Compared to the result of the inspection of the manufactured car exhaust gas, the result of the inspection of the vehicle exhaust gas greatly varies depending on the state of the vehicle, especially the engine condition, even though the same model and the same model of the vehicle are used. The worse the engine condition, the worse the exhaust gas test result.

On the other hand, in the conventional used car transaction, the price was formed by the yearly appearance, the appearance and the option without an accurate judgment of the engine condition, and the result of the inspection of the running vehicle exhaust gas was not utilized.

Korean Registered Patent No. 10-0694821 (March 14, 2007) Korean Patent Laid-Open No. 10-2003-0089061 (November 21, 2003)

Conventionally, the used car quality authentication method and its system include a reception terminal that receives reception information of a vehicle and transmits the information to a vehicle information providing server and receives and stores corresponding vehicle information, and receives reception information from the reception terminal A function of receiving the vehicle information of the vehicle to be inspected from the vehicle selection terminal, and a function of outputting the list to the reception terminal, An inspection device and a visual inspection terminal for receiving the vehicle information of the inspection subject vehicle and performing the inspection of the vehicle and transmitting the inspection result to the diagnostic terminal, And transmits the data to the DB server or generates necessary statistical data. Bars are also configured.

Another conventional method of supporting used car evaluation and pricing with a conventional used car transaction support system is to build a transaction history DB and support the quality evaluation and pricing of the target vehicle through the data communication network, And a method for supporting the used-car quality evaluation and pricing, wherein the system is configured to record and input inspection data for evaluating the quality of the vehicle and identification information of the vehicle to be traded, respectively A recording input unit; An information processing storage unit for collecting inspection data inputted from a recording input unit to generate quality evaluation information of the vehicle and calculating a price of the vehicle according to the quality evaluation information; The quality evaluation information and the price calculation information are connected to the information processing storage unit so that they can be searched and browsed, and the quality status and price calculation information of the used car used as the transaction target are provided.

In this way, conventionally, the vehicle information of the inspection subject vehicle inputted from the diagnostic terminal for the used car transaction is received and the inspection of the vehicle is performed and the inspection result is transmitted to the diagnostic terminal. Alternatively, the inspection data And the identification information of the target vehicle, the quality status of the target vehicle and the pricing information are provided. However, since the price or quality of the used car thus determined is relative to each vehicle, it depends on the comparison target, and there is an unreasonable point that the same price is assigned to the same used car even for a consumer. In other words, there are no quantified standards such as the data on the results of the inspection of the vehicle emissions for comparison between used cars, which causes disbelief in the used car transaction price itself. Moreover, even if it is the same year (vehicle production year), the degree of aging of the vehicle varies depending on how and by whom the vehicle is used, but the evaluation of the used car price is not evaluated.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a method for evaluating the quality of a used car engine from automobile emission data based on a car name and determining a price for a used car transaction.

In order to achieve the above object, the present invention provides a method for evaluating the quality of a running vehicle according to the exhaust gas inspection information, comprising the steps of: (a) extracting exhaust gas inspection information and a mileage information Preparing an exhaust gas inspection integrated information DB for classifying exhaust gas information by the same automobile name; Deriving a relationship between a yearly and an exhaust gas amount by the same car name based on any one of several exhaust gas components from an exhaust gas inspection integrated information database; Calculating a real year model within the same car name from the relationships between the relationship between the model year-end emission amount and the mileage-emission amount relationship of the target vehicle; And a control unit.

The price of a general used car is formed according to the appearance of the vehicle or an option based on the production year of the vehicle. However, consumers who purchase and use these products are more likely to experience unexpected flaws in their used cars after purchasing, rather than appearance, options, and model year. Only by being able to make a big contribution to the activation of used car dealings.

In addition, by integrating exhaust gas inspection information and automobile name database, it is possible to expand the comparison group of quality by calculating data based on the name of the car, as in the case of the sonata and the NF sonata, .

In addition, through the concept of the yearly profit, it is possible to accurately evaluate actual vehicle performance or vehicle aging, not the production year of the previous vehicle.

1 shows a method of evaluating the quality of a running vehicle based on exhaust gas-based mileage and exhaust gas inspection information.
FIG. 2 shows a method of calculating a used vehicle price based on exhaust gas-based mileage and exhaust gas inspection information.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood that the present invention is not limited to the described exemplary embodiments, The present invention is not limited to these embodiments.

The exhaust gas inspection information is information on the exhaust gas (CO, HC, NOx, soot) as a result of the exhaust gas inspection of the close inspection among the comprehensive inspection details of the automobile. It is divided into 16 categories such as car name, model year, fuel type, engine type, exhaust amount, vehicle weight, fill weight, mileage, and the inspection information includes inspection name, inspection date, And inspection method, and the inspection result is divided into CO, HO, NOx, soot and the judgment value.

The car name or car name described in the present invention means the generic name of the car model set by the automobile manufacturer. A model can be distinguished by model year and model even if it has the same name. Therefore, the Sonata and LF Sonata are the same as the Sonata, and are different models depending on the model year, engine type, fuel, and displacement. Therefore, the scope of the classification object is different when the classification is based on the name of a car and on the basis of the model. The model has an advantage that the comparison object is more clear than the car name, and the car name is a model There are advantages.

Accordingly, it is possible to extract vehicle model (s) from the vehicle name DB and exhaust gas inspection information by using information on automobiles (eg, name of car) in the exhaust gas inspection information database and some data such as name, year, If exhaust gas inspection information is collected and DB is made, the range of the automobile covered by the same model as well as the same car name can be grasped.

By integrating with the emission gas inspection information and constructing the integrated information DB of the vehicle emission gas inspection, it can include information about the model as well as information about the name of the car. At this time, the driving vehicle emission gas inspection integrated information DB may mean a single physically integrated DB, but the present invention is not limited to this, and it can be realized that data can be retrieved by connecting each DB.

When the user inputs the vehicle number or the vehicle specification, the vehicle information such as the name and the model can be confirmed from the running vehicle emission gas inspection integrated information DB stored in the computer. Namely, an automobile name DB is combined with the information on exhaust gas inspection information for each of the automobile models. For example, in the exhaust gas inspection information, only the sonata is recognized as an LF sonata as an automobile name DB is added. Hereinafter, the processing of the exhaust gas inspection information is performed on a computer basis.

In the present invention, the concept of the yearly profit is proposed as a method of using the emission gas inspection information to evaluate the quality of the running vehicle. Yearly means the year of production of the vehicle. Yearly profit means the time (year) profit for the year of production if it is older than the year of production or vice versa. For example, even if a vehicle is produced 10 years before the year of service, it may actually have a quality equivalent to that of a car that is only 7 years, or on the contrary, it may have an aged quality of 15 years have. In this case, each yearly profit will be +3, -5 if there is no correction. From this, it is possible to know the vehicle grade, that is, the quality of the actual vehicle, which is different from the production year, by the quantitative value based on the year. The index indicating the quality of the vehicle that reflects the yearly profits is called the operating year index and is obtained by calibrating the year of production as the annual profit.

The method of evaluating the quality of service vehicle is divided into the method based on the exhaust gas, the method based on the amount of exhaust gas in detail, and the method based on the mileage according to the amount of exhaust gas.

First, the method based on the amount of exhaust gas itself involves estimating the real year model of the vehicle to be evaluated using the emission information of the same automobile name.

First, the relationship between emission gas information and vehicle production year is derived for the same car name. Since the exhaust gas information for the vehicle production year is updated every time a single vehicle carries out the emission inspection on a regular basis, the average value of the exhaust gas amount can be calculated by integrating the latest emission information for the vehicle production year of the same car name, From this, a two-dimensional graph of the average emission gas of the same car name by vehicle production year is obtained.

After obtaining a two-dimensional graph of the average exhaust gas amount per vehicle production year, the amount of exhaust gas of the vehicle to be evaluated can be substituted and the corresponding production year of the vehicle can be obtained. If the engine condition of the vehicle to be evaluated is good, the latest year of the vehicle to be evaluated will be obtained from the actual vehicle production year of the vehicle to be evaluated. On the contrary, if the engine condition of the vehicle to be evaluated is poor, Will be obtained. This is defined as real year.

The difference between the actual vehicle production year of the vehicle to be evaluated and the year obtained from the two-dimensional graph of the average exhaust gas amount per vehicle production year is the annual profit obtained from the exhaust gas amount. For example, a yearly profit of two years means that the engine has a better engine condition than the actual year of production of the vehicle by about two years. That is, the relationship between the actual yearly-vehicle production year and the yearly profit is established, and the yearly profit can be used as a yearly index of the vehicle as it is, or as a correction value for the vehicle production year.

From the two-dimensional graph of the average exhaust gas amount per vehicle production year from the exhaust gas amount of the evaluation target vehicle, the vehicle sequence is confirmed, and the yearly profit is calculated from this, and the vehicle production year is corrected. To obtain a yearly index.

For this purpose, the position (sequence) of the vehicle to be evaluated for the same car name should be confirmed. This is expressed in the form of a two-dimensional graph, in which the x-axis is the average and the y-axis is the average exhaust gas amount in the same name. That is, from the relationship between the vehicle name and the average exhaust gas amount from the vehicle information exhaust gas inspection integrated information DB including the name of the vehicle and the exhaust gas inspection information by model, the actual vehicle model corresponding to the average exhaust gas amount .

In other words, even in the exhaust gas inspection information DB, the same model name is different from the vehicle model DB. By integrating them, the relationship between the amount of exhaust gas to the same vehicle name is obtained from the exhaust gas inspection integrated information database, As the amount of exhaust gas increases, the amount of exhaust gas decreases with recent years. Therefore, the actual yearly expression is obtained from the amount of exhaust gas of the vehicle to be evaluated.

For example, in the case of an evaluation based on the CO value of the Sonata 2010 model car, first, after the exhaust gas inspection information group of the car name of the vehicle is derived from the exhaust gas inspection information DB, Can be known. The vehicle emissions can be based not only on CO but also on other emission values such as HC and CO2. The actual position can be confirmed from the correlation between the model year and the amount of exhaust gas of the evaluation vehicle based on the amount of exhaust gas of the automobile name. Here, the position means the vehicle production year or year, which is x-axis in the two-dimensional graph.

Second, the method based on the mileage according to the amount of exhaust gas is to calculate the mileage profit of the evaluated vehicle and the actual mileage from it using the annual average mileage information based on the exhaust gas of the same automobile name from the exhaust gas inspection integrated information database It relates to estimating the yearly rate.

Emissions are related to the performance of the vehicle engine, and mileage is closely related to vehicle aging. It is desirable to simultaneously consider the performance of the vehicle engine and the overall degree of aging of the vehicle in evaluating the vehicle. Of course, even if the vehicle is aged, the evaluation of the old age may be changed due to the replacement of the parts. In the present invention, however, the evaluation of the old age of the vehicle which is difficult to replace is targeted. Therefore, the evaluation of the degree of aging of the vehicle is derived from the correlation between the exhaust gas and the running distance by pointing out the point related to the running distance.

A comparison of the CO value of a vehicle to know the running vehicle rating and the average CO value by mileage can be used to find the mileage corresponding to the CO value of the vehicle to be evaluated. That is, when the CO distance is compared with the actual travel distance of the vehicle to be evaluated based on the CO value, it is possible to compare the short or long travel distance with the CO distance based on the CO value.

To this end, the relationship between the average annual mileage based on the emission gas of the same automobile name is first obtained. This is expressed in the form of a two-dimensional graph, in which the x-axis is the exhaust gas and the y-axis is the average annual running distance in the same name. When the amount of exhaust gas of the evaluation target vehicle is applied to the graph of the above relationship, an average mileage based on the amount of exhaust gas of the evaluation target vehicle is derived. This is because the engine condition of the evaluation target vehicle is the average mileage It means the same as the engine condition. Therefore, the difference between the average running distance and the actual running distance of the vehicle to be evaluated becomes the running distance gain of the vehicle to be evaluated.

The mileage profit is calculated from the formula ((vehicle model year - vehicle model year) * annual average mileage - actual mileage). The year of the vehicle is calculated from the value stored in the exhaust gas inspection integrated information database. This means that the average mileage corresponding to the actual mileage and the amount of exhaust gas And obtains the travel distance gain from the travel distance.

That is, if the actual distance traveled by the vehicle to be evaluated is larger than the average travel distance, it means that the vehicle aging has proceeded much more because the vehicle travels more despite the average distance traveled by the vehicle. On the other hand, if the actual traveling distance of the vehicle to be evaluated is less than the average traveling distance, it means that the vehicle aging is less progressed because the vehicle travels less, even though the average traveling distance is adequate.

The travel distance gain can be obtained from the relationship between the average travel distance corresponding to the amount of exhaust gas and the travel distance according to the actual year model, and this can be converted into the annual gain. For example, if a vehicle produced in 2011 corresponds to a CO mileage calculated from the CO-mileage relation calculated from the exhaust gas inspection integrated information database, the CO value measured as of 2015 is equivalent to 70,000 km, By engine performance alone, this means that it is equivalent to a 70,000 km engine. On the other hand, in order to calculate the average mileage of the same car name, the average annual mileage of the same car name is multiplied in that period (year). That is, if a vehicle with the same name carries an average of 20,000 km per year for the same period, it will be 20,000 km - 70,000 km = 30,000 km (2015 - 2011), resulting in a mileage profit of 30,000 km, The gain is 30,000 km. In other words, it means that it has engine performance that can run 30,000 km more.

The annual gain is obtained by dividing the mileage gain by the average annual mileage. That is, the annual gain is obtained by comparing the mileage with the average mileage on the basis of the exhaust gas, and when it is applied to the example, the yearly gain is 1.5 years because the mileage is 30,000 km / 20,000 km.

Based on the average mileage-based annual gain, the vehicle production year can be corrected to calculate the mileage-based vehicle mileage index. The correction method for the yearly gain of 1.5 years in the year of production of the vehicle is June 2012 only in the case of the summation method, and the correction method may set a certain ratio in addition to the summation method.

Third, the weighted average annual indicator of the operating vehicle can be calculated by weighting each of the exhaust gas-based operating mode index and the average mileage-based operating mode index calculated by the operating mode annual index calculation method. For example, a 1: 1 ratio of emissions-based and annual mileage-based driving aids is 1: 1, the emission-based driving aids are 2012, and the mileage-based driving aids are 2014 The average annual average index is 2013.

Fourth, furthermore, it can be applied to the calculation of the vehicle price by the vehicle average annual indicator by the calculation method of the vehicle age index. Generally, the driving vehicle price is calculated by the standard value of the driving car according to the appearance of the vehicle including the year of production of the vehicle. As an important factor of the performance of the vehicle, the engine condition and the fuel efficiency of the vehicle can be calculated from the average vehicle- have.

For example, the expected value of a vehicle can be calculated from the average value of the yearly price based on the weights and the year of manufacture of the vehicle, giving the original yearly, that is, the price based on the vehicle production year, twice the weight. On the other hand, if the price of the vehicle is set at the monthly unit rather than the annual unit, it can be converted to the monthly unit.

On the other hand, as in the case of the Sonata and the NF Sonata, if the names are the same, but the models are different, there is an advantage in expanding the comparative group of quality by integrating the data by treating it as the name of the sonata.
