Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a used car trading system for properly buying and selling used cars between general users. In addition, the present invention relates to a used car sales price prediction system used in a used car trading system for predicting an appropriate price of a used car, and a used car user auction system for executing an auction in which general users can participate.

[0002]

2. Description of the Related Art When a used car seller sells a used car, it is generally sold to a used car trader or the like, or sold as a trade-in at a new car sales company or the like. At this time, the purchase price and the trade-in price of the used car are calculated with reference to the so-called trade price between traders in a used car trade auction or the like in which the used car trader participates. In this used car auction, since a large number of used cars are traded, they are traded at almost appropriate prices based on supply and demand.

On the other hand, in addition to the above-described transaction form, there is also a transaction form in which general users who are final consumers directly buy and sell used cars. In this case, there is no need to pay commissions and the like to used car dealers and the like, so the seller can be higher and the buyer can buy and sell used cars at a lower price. In this case, the purchase price is often determined by referring to the purchase price or the retail price of the used car of the used car dealer.

[0004]

However, the direct trading by the general user described above has the following problems. In other words, since it is extremely rare that used cars with the same conditions appear on the market, the selling price of used cars that fluctuates greatly depending on the model, year, mileage, inspection time, body color, mounting options, vehicle condition, etc. Is difficult to calculate properly.

[0005] In addition, since general users cannot participate in auctions, it is difficult to know the transaction price between used car dealers. It is difficult to calculate the selling price of a used car subject to the above.

[0007] Therefore, the present invention can calculate an appropriate used car sales price that is close to the transaction price between traders even if it is a general user, and promotes the transaction between the general users, thereby promoting the general user. It is an object of the present invention to provide a used car trading system, a used car selling price prediction system, and a used car user auction system that can smoothly carry out a trade between cars.

In addition, as this user trading result information, the trading result established by the used car trading system 10 is mainly input.

The auction system 70 includes a central processing unit 71 that performs various arithmetic processing and commands and is connected to a communication line 150 such as a telephone line or the Internet. The communication line 150 includes terminals 151 to 1 on the buyer side.
53 is connected, so that the buyer can know the supplementary information and the current price Q, and can input the bid price L. The central processing unit 71 has additional information,
Predicted trading price P, current price Q, initial price S, standard value P1 of trade-in / purchase actual price, standard value P2 of actual auction actual price, standard value P3 of actual retail price, standard value P4 of actual user price Information storage unit 7 in which is stored
2 and a management unit 73 that communicates with the buyer. Note that the current price Q is the same as the initial price S at the start of the auction, but is appropriately changed according to the price input via the communication line 150.

In the used car trading system 10 configured as described above, the used car is bought and sold as follows. Note that the following preparations are made in advance in order to obtain the predicted purchase price P of the used car.

That is, the information updating unit 32 uses a terminal 111-113 of a trader and an information providing user via a communication line 110 such as a telephone line or the Internet to exchange a used car at a car dealer such as a dealer. Trade-in / purchase result information such as the purchase price of the car dealer is input. Along with the trade-in / purchase result information, a price difference due to a difference in each element (for example, body color) of the accompanying information is stored in the storage unit 33.

The information updating section 42 receives information on the auction results between used cars from an auction site held by a used car dealer through a communication line 120 such as a telephone line or the Internet. Along with this inter-trade auction result information, the price difference resulting from the difference in each element of the accompanying information is stored in the storage unit 43.

The information updating unit 52 receives retail performance information from a retailer via a communication line 130 such as a telephone line or the Internet. Along with the retail performance information, a price difference due to a difference in each element of the supplementary information is stored in the storage unit 53.

The information updating unit 62 receives user trading result information via a communication line 140 such as a telephone line or the Internet. Along with the user transaction information, the price difference resulting from the difference in each element of the supplementary information is stored in the storage unit 63.

Next, based on the trade-in / purchase record information, the auction record information between traders, the retail record information, and the user trade record information, a correlation database between these record information is obtained. That is, the predicted trading price P is closest to the price according to the user trading result information directly traded between the users. However, the user trading results information has fewer examples than the trade-in / purchase results information, the inter-trade auction results information, and the retail results information, and it is difficult to obtain the correct predicted trading price P. Therefore, supplementary information without data is complemented by obtaining a trade-in / purchase result information, an inter-trade auction result information, and a correlation database between the retail result information and the user trade result information.

For example, a case will be described in which a correlation database is actually obtained based on a used car α having user trading information. This used car α is actually the standard value P4
Let's say that it was sold for 3.5 million yen. Next, the trade-in / purchase result information of the used car most similar to the used car α is extracted from the storage unit 33, and the adjustment unit 34 is adjusted to match the used car α.
In, the price is increased or decreased according to each element of the supplementary information. The used car α is not a specific one, but a more accurate price is required if a plurality of similar used cars are comprehensively determined and determined. The price of the used car α is reduced by, for example, 100,000 yen when the model year is one year old, and increased by 50,000 yen when the car navigation system is mounted. In addition, the price is adjusted by each element of the supplementary information such as the body color and the mileage. The price after such an increase or decrease is sent to the central processing unit 21 as a standard value P1. Similarly, standard values P2 and P3 are obtained.

The standard value P1 calculated as described above
Is assumed to be 3 million yen, the standard value P2 is assumed to be 3.4 million yen, and the standard value P3 is assumed to be 4 million yen. P1: P2: P3: P4 = 100: 110: 140: 115 (1) P1 + 15 = P4 (2) P2 + 5 = P4 ~ (3) Four types of correlation databases P3-25 = P4 ~ (4) are obtained. Therefore, if the standard value P1 of another used car β is 2 million yen, the standard value P2 is 2.1 million yen, and the standard value P3 is 2.7 million yen, P4 is calculated based on the equations (1) to (4). When calculated, it can be seen that the range is 215 to 2.46 million yen. That is, the predicted trading price P is 215 to 2.46 million yen. Such a correlation database is stored in the correlation storage unit 23.

Next, a case where a used car seller sells used car γ will be described. Sellers use used cars γ
Bring in. The member store or the seller user inputs the supplementary information of the used car γ and the selling price M of the seller to the terminals 101 to 10.
Enter 3 The supplementary information and the desired sale price M are input to the central processing unit 21 via the communication line 100 and stored in the supplementary information storage unit 22.

In the central processing unit 21, an auxiliary information storage unit 22
The standard values P1 to P3 corresponding to the used car γ are calculated based on the supplementary information stored in. That is, a plurality of similar used cars δ1 having additional information similar to the additional information of the used car γ are extracted from the storage unit 33 of the trade-in / purchase result extraction unit 30, and the adjustment unit 34 determines the respective elements of the additional information. The price is increased or decreased due to the difference, and a standard value P1 is obtained.

Similarly, based on a plurality of similar used cars δ2 stored in the storage unit 43 of the inter-business auction result extraction unit 40, the standard value P2 and the similarity stored in the storage unit 53 of the retail result extraction unit 50 The standard value P3 is obtained based on a plurality of used cars δ3.

The trading price calculation unit 24 calculates the correlation value stored in the correlation storage unit 23 with the standard value P.
A predicted trading price P is obtained based on 1 to P3.

Next, a normal auction procedure in the auction system 70 will be described. The predicted trading price P obtained by the trading price prediction system 20 and the desired selling price M stored in the accompanying information storage unit 22 are input to the central processing unit 71 of the auction system 70.

The central processing unit 71 sets the initial price S of the auction based on the predicted sale price P and the desired sale price M, and stores it in the accompanying information storage unit 72 together with the accompanying information. The initial price S is disclosed to the buyer as the current price Q along with the standard values P1 to P4 via the communication line 150 such as the Web.

When the buyer wants to buy a used car δ, he inputs a bid price L higher than the initial price S through the terminals 151 to 153. Bid price L is communication line 150
, And the current price Q is updated to the bid price L. New current price Q is communication line 150
Will be released to buyers via. Similarly, a new bid is awaited, and when a new bid price L is input, the current price Q is updated.

If there is no new bid even after a certain period of time, the used car γ is sold at the current price Q.
In the management unit 73, a communication is sent to the buyer who has bid the current price Q via the communication line, and the buying and selling of the used car γ is established.

On the other hand, in the case of a so-called price down auction, the initial price S is set to be higher than the predicted trading price P. The initial price S is disclosed as the current price Q together with the accompanying information, and bidders are invited. If there is no successful bidder within a certain period, the current price Q is lowered and re-released. The same procedure is repeated, and when the successful bidder comes out, the process ends and the used car γ
Is established. When a successful bidder comes out at the same time, the current price Q is increased.

In the above-mentioned ordinary auction and price down auction, if the current price Q when oneself bids is updated by another person making a bid at a higher or lower price, the mobile phone The management unit 73 may contact a portable mobile terminal such as a mobile phone or a pager. In this case, there is an advantage that the buyer does not need to constantly monitor the Web.

Further, in the case of a push-type simultaneous auction, a plurality of buyer users participate in the auction at the same time via the Internet. For example, the initial price S is disclosed as the current price Q together with the supplementary information, and a successful bidder is invited. If any of the buyer users makes a bid using a bid key (for example, an Enter key), the current price Q increases by 10,000 yen and the current price Q becomes 1.01 million yen.

Similarly, if any of the other buyer users makes a bid using the bid key, the current price Q becomes 1.02 million yen.

This operation is repeated for a certain period of time (for example, 3
If there is no further bidding within 0 seconds) and the price exceeds the desired sale price M, the final current price bidder becomes the successful bidder.

As described above, in the used car trading system 10 according to the present embodiment, even a general user who is difficult to know the trade-in / purchase results and the inter-trade auction results can know the predicted trading price P. Can be.

Further, by using a widely used communication line such as the Internet, even a general user can easily participate in an auction.

The present invention is not limited to the above embodiments. That is, in the above-described embodiment, the correlation database is determined from the simple ratios and price differences of the standard values P1 to P4. , The trading prediction price P may be calculated more accurately. Although the trade-in / purchase record information, the inter-trade auction record information, and the retail record information are used as the record information, record information other than these may be used.

Although the telephone line and the Internet are illustrated as the communication lines, other communication lines such as a mobile phone, a PHS, and a pager may be used. In addition, it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0054]

According to the present invention, even a general user can calculate an appropriate used car sales price close to the transaction price between traders, and can promote the transaction between general users. It is an object of the present invention to provide a used car trading system, a used car trading price prediction system, and a used car user auction system that can smoothly perform trade between general users. Further, even a general user can enjoy the price advantage.
