It was not possible to know the exact value of many types of cars with the same name.

[0004]

By the way, the price of a used car has various factors other than the depreciation factor over time.

For example, there is a big difference in price between a popular model and a popular color vehicle in the used car market and other vehicles even if they are of the same grade.

Further, high-performance models sold for a limited production period are still popular in the market even after 10 years have passed, and there are specialty stores handling these old-model vehicles.

Further, the market situation of the used car market as described above is constantly changing, and even if the vehicle is traded at a high price for a certain period of time, its popularity is often reduced thereafter.

[0008] In addition to this, the market price of a used car may be different even if the specification of the vehicle is slightly changed (minor change).

For this reason, it is indispensable for a dealer handling a used car to grasp the exact model and detailed specifications of the vehicle and further grasp the market trend.

However, although general depreciation tables for automobiles are relatively easy to obtain, it is difficult to grasp various information unique to used cars as described above, which is an obstacle to distribution of used cars. Was there.

Further, there are cases where the original specifications are unclear when a mark that can identify individual specifications such as a vehicle emblem is removed.

The present invention has been made in order to solve the above-mentioned matters, and it is possible to easily and accurately retrieve the market price of a used car that varies according to detailed specifications and conditions. To provide the technology.

[0013]

In order to solve the above-mentioned problems, the present invention has the following means.

That is, the vehicle attribute data regarding the used vehicle for which the price search is performed is accepted, and the used vehicle price data including the market price data and the variable price data of the vehicle is calculated from the storage means based on the vehicle attribute data. .

By such means, the present invention makes it possible to easily and accurately retrieve the market price of a used car that differs according to detailed specifications and conditions.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a used car price search method according to the present invention will be described below with reference to the drawings.

In this embodiment, the used car price search method of the present invention is implemented by connecting a server device and a search terminal to the Internet (TC).
P / IP: Transmission Control Protocol / Internet P
It is realized as a system that is connected through a general-purpose network such as a data transfer network by rotocol) and performs necessary data search from the server device or the search terminal side.

FIG. 1 is a diagram showing an outline of an example of a system configuration for realizing the used car price search method according to the present embodiment. In FIG. 1, the server device and the search terminal are denoted by reference numerals 100 and 200, respectively. The server device 100 and the search terminal 200 are connected to a general-purpose network such as the Internet described above.

Next, the server device 1 according to the present embodiment
00 will be described with reference to the schematic configuration diagram shown in FIG.

First, the server device 100 has a CPU (ce
ntral processing unit) 101 and main memory (MM)
And an arithmetic processing unit 103 configured to perform processing based on an application program.

A storage device 104 is connected to the arithmetic processing unit 103 as a storage means of the present invention via a bus 108. A large-capacity storage medium such as a hard disk device is usually used as the storage device 104.

An operating system (OS) required for the server device 100 to function normally is installed in the storage device 104.

An existing application program is installed in the storage device 104.

Further, the storage device 104 is created to implement the used car price search method of the present invention.
A second-hand car price search program that can be executed by a computer is installed.

These programs are stored on a CD-not shown.
The CD-ROM drive device 1 shown in FIG. 2 stored in a storage medium such as a ROM and provided to the server device 100.
09, etc., and is installed in the storage device 104 in an executable state.

Then, the CPU 101 loads (reads) the used car price search program in the storage device 104 into the main memory 102 as needed, and sequentially executes the program, whereby the server device 100 executes the used car price search method of the present invention. The vehicle attribute data receiving means and the used vehicle price data calculating means for implementing the above are realized.

Further, in the storage device 104, various databases necessary for realizing the used car price search method of the present invention are stored.

In the present embodiment, the databases stored in the storage device 104 are a vehicle type database, an year model database, a specification database, a mileage deviation database, and a market situation database.

The vehicle type database is a group of vehicles classified by model designation number and classification. The model designation number is a number given when the vehicle is approved by the Ministry of Transport, and the category classification is a number indicating the grade of the vehicle (number of doors, setting of equipment such as sunroof).

The year database is an array of market prices for each year associated with the vehicle model database. In the case of automobiles, the market price reduction is generally calculated on a monthly basis.

The specification database is a database of so-called grade differences as price differences, and independent prices are attached even with slight differences in specifications.

Generally, there are several tens of types of automobiles, even if they have the same name, due to differences in displacement and grade, and if a slight difference in grade is added, there will be several hundreds in a permutation combination formula. Sometimes it becomes. In the present embodiment, prices are attached to all of these vehicle types. The price setting due to the color difference is also stored here.

The mileage deviation database is designed to give a high evaluation amount to a vehicle having a short mileage.

The database is constructed in this way in order to obtain a higher evaluation amount for a vehicle having a shorter mileage in the market of used cars. Therefore, according to the present invention, a more substantial price calculation can be performed by adding the mileage deviation database. In this database, a reasonable annual mileage is set for each vehicle type, and a large depreciation is set for those that greatly exceed this.

The market status database is a database that stores market status information indicating popularity such as transaction volume and transaction price in the used car market of each vehicle type. Automobiles are also a subject of hobbies, so whether or not there is a market situation greatly affects the used car market. Therefore, a popular vehicle may be traded at a higher price than its real value as an automobile. It should be noted that it is preferable to regularly update the data in this database because the market situation at the market price changes from moment to moment.

In addition to the above, an OS is stored in the storage device 104.
Alternatively, a database used by various normal application software is stored.

Further, the arithmetic processing unit 1 of the server device 100
Input means and output means are connected to 03 via a bus 108. First, an input device such as a keyboard 107 or a mouse for inputting various information is provided as an input unit.

Next, an example of the database in the present embodiment is shown in FIG.

In the database 10, [approved model]
All have the same symbolic numbers, but the classification is vehicle 10
001 for a, 004 for vehicle 10b, and vehicle 10
c is different, such as 006. This is because the equipment of each model is different, which means that the grade of the car is different.

In the database 10, [shape] indicates the style of the vehicle body. An example of the abbreviation is S
D: Sedan, HB: Hatchback, LB: Liftback, CO: Coupe, HT: Hardtop, WG: Wagon, SW: Station Wagon, MB: Minivan, O
P: Indicates open, respectively. In addition, all the vehicles on the database 10 in the present embodiment are hatchbacks.

On the other hand, the abbreviations of the equipments are P / W: power window, P / S: power steering, A / C: air conditioner, S / T: stereo, A / W: aluminum wheel, AB
S: ABS, A / B: airbag, S / R: sunroof, NAV: navigation system, respectively.

In the database 10, the number of doors (3), capacity (5 persons), mission type (5-stage manual mission), drive system (front engine full time 4WD), and fuel (gasoline) are stored in the database 10. Shown,
Finally, the price of the car body is stored. In the present embodiment, as an example, the first half and the second half of 1999 are displayed separately.

Next, the server device 1 according to the present embodiment
The processing performed by 00 will be described with reference to FIGS. 4 and 5.
