Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a method and an apparatus for estimating the price of a used vehicle.

[0002]

2. Description of the Related Art In general, the assessment price of a used vehicle is generally determined from two factors: "market needs for a used vehicle" and "state of the used vehicle itself". The "market needs for used vehicles" can be determined almost completely from past market trends if the vehicle manufacturer, model, paint color, the presence of equipment, etc. are known, but the "state of used vehicles themselves" is accurate. It is generally difficult to judge. The "condition of the used vehicle itself" includes a state that can be determined by appearance such as the presence or absence of scratches and the degree of dirt on the vehicle body and interior parts, and a state that cannot be determined by appearance such as the degree of deterioration of the vehicle due to use of the vehicle. In particular, in the latter case, in particular, it is often difficult to determine the exact location unless the vehicle is actually maintained.
However, since vehicle maintenance cannot be performed at the time of the assessment, it has generally been determined from the relationship between the number of years of use and the mileage (for example, Japanese Unexamined Patent Publication No. 9-044563).
JP, JP-A-11-184910, JP-A-11-184910
1950069, JP-A-9-251486).

[0003]

The years of use and mileage are important indicators for judging the "condition of a used vehicle itself". The condition of the used vehicle itself is greatly affected by the status of maintenance, such as when the vehicle has been replaced, the road used (paved road or mountain road, etc.), and the location of use (shore, etc.). If the "state of the used vehicle itself" is determined based on only the distance (merely the accumulated traveling distance), the determination may be erroneous. In the past, it was difficult to know the actual maintenance status and usage status as described above, so from the current surface condition of the vehicle such as years of use, mileage, appearance (scratch, tire wear, corrosion, etc.) Evaluation had to be done with items that could be judged. Therefore, when buying or selling or trading in used vehicles, we will make an assessment lower than the actual value in anticipation of the risk for the actual condition of the used vehicle itself that is not available and the guarantee at the time of problem occurrence, There was a problem that the seller (user of the vehicle) was likely to be dissatisfied. Also, when conducting maintenance after purchasing a used vehicle, since the status of the maintenance up to now is unknown, excessive maintenance may be performed, so unnecessary maintenance costs may increase and the used vehicle sales price may increase. There was also a problem.

The present invention has been made to solve the problems of the prior art as described above, and the maintenance status and the usage status are fetched into a database and utilized for evaluation, whereby the "state of the used vehicle itself" can be obtained. It is an object of the present invention to provide a used vehicle evaluation method and apparatus that can accurately detect and enable more accurate evaluation.

[0005]

The effect is obtained.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the general concept of the present invention. In FIG. 1, a vehicle user (owner) 1, a vehicle 2, a management company 3, a vehicle maintenance company 4, a vehicle sales company 5, a used vehicle purchase company 6, and an auction for buying and selling vehicles at an auction. The company 7, the assessment database (abbreviated as DB in the figure) 8, the maintenance status database 9, and the usage status database 10 can communicate with each other via the Internet 11.

The management company 3 manages this evaluation system, and is separately shown in FIG. 1, but may be shared by the maintenance company 4, the sales company 5, the purchase company 6, the auction company 7, and the like. Note that the above 3 to 7 are described as “company”, but are not limited to legal corporations, and are used in the sense of so-called “traders”. Although the assessment database 8, the maintenance status database 9, and the usage status database 10 are shown to be directly connected to the Internet 11, they may be connected via the management company 3. The Internet 11 is an example of a communication method, and may be another type of two-way communication network. The user 1 can connect to the Internet 11 via a personal computer or a mobile device, and the vehicle 2 can be connected to a communication device (for example, also used as a navigation device) from a vehicle-mounted computer.
Can be connected to the Internet 11 via. Alternatively, as shown by a broken line in FIG. 1, the information may be directly input to the maintenance status database 9 or the usage status database 10.

Hereinafter, the assessment database 8, the maintenance status database 9, and the usage status database 10 will be described. First, the assessment database 8 is a database that stores data corresponding to general assessment items that have been conventionally used when assessing used vehicles. The assessment items include a manufacturer name, a vehicle type, a type, and a grade. , Year, and paint color, and current items such as optional parts and body appearance such as wear of the vehicle (those that can be discriminated by the appearance, including the interior).

Next, the maintenance status database 9 roughly includes the following four types of data. (1) Replacement data of consumable parts such as tires, brake pads, oil, etc. (2) Inspection and maintenance data such as periodic inspections and vehicle inspections (3) Accident and failure repair data (4) Engine control system and drive controlling the vehicle Basically, the above data are input to the maintenance status database 9 by the maintenance company when maintenance or repair is performed by the maintenance company. For example, when a sales company first sells a vehicle,
Enter the number of the vehicle in the maintenance status database 9 and register it. After that, when a maintenance company performs replacement of consumable parts, periodic inspection and maintenance, vehicle inspection maintenance, or repair in the event of an accident or breakdown, the content of the operation is Is input to the maintenance status database 9. The above maintenance status is input together with the accumulated traveling distance up to that point. Further, in a vehicle in which replacement of oil, brake pads, and the like can be detected by a vehicle-mounted control computer, the contents may be input to the maintenance status database 9 via communication means such as a navigation device. Further, when the user 1 performs maintenance independently, the contents of the maintenance may be input to the maintenance status database 9 via the Internet 11. The storage contents of the on-board control computer and the maintenance contents of the user are stored in the control computer, and are stored in the maintenance status database 9 at the time of maintenance or assessment through a removable disk or card. You may enter it.

If the failure data is stored as described above, when a similar failure occurs, the sales company or maintenance company checks the maintenance status database 9 to determine the location of the problem from the past maintenance contents. And it is easy to investigate the cause.

Next, the usage status database 10 is roughly divided into the following three types of data. (1) Driving distance data for each traveling road (2) Location data (3) Data for each weather The traveling road data is an accumulated traveling distance for each road surface condition on which the vehicle actually traveled, and is, for example, a plain area. (Pavement roads) and mountain areas (uneven terrain) are calculated separately. Recently, vehicles for rough terrain such as RVs and SUVs are popular. However, users of these vehicles do not necessarily travel on rough terrain such as mountain roads, but often use only on urban paved roads. Since the wear of the vehicle has a large difference between traveling on paved roads and traveling on uneven terrain such as mountain roads, if the contents of paved road traveling and traveling on irregular terrain in the total accumulated traveling distance are known,
Evaluation can be performed accurately. In order to separately calculate the pavement road and the mountain road as described above, a current position confirmation process using a vehicle navigation device or the like is used. That is, when the current position of the vehicle is in a city or a plain area, the travel distance is integrated as a plain area, and when the vehicle is at a mountain position, the travel distance is integrated as an irregular land. This content is stored in the usage status database 10 via communication means such as a navigation device.
Can be input to the computer, or stored in a vehicle-mounted computer, and used during maintenance or assessment via a removable disk or memory card.
It may be input to 0.

The location data is data of the location where the vehicle was mainly located, that is, the location where the vehicle was used or parked. For example, a vehicle used at the seaside often loses evaluation because the body often rusts due to salt damage. This data uses the current location confirmation processing by a vehicle navigation device or the like in the same manner as the data for each traveling route,
Remember over time.

The weather-specific data is data indicating the degree of wear due to snow, hail, hail, etc., and is also data for evaluation loss. This data can be obtained by detecting with the output of the temperature sensor or rain sensor on the vehicle (when the temperature is below the freezing point and the output of the rain sensor is detected), or by the current location confirmation processing by the navigation device of the vehicle or the like by the Meteorological Agency or Meteorological Company. It can be obtained by a method that is used in combination with weather information.

FIG. 2 is a block diagram of an embodiment of the arithmetic unit according to the present invention. In FIG. 2, the first calculating means 1
2 calculates a basic evaluation value based on the contents of the assessment database 8. The details of the operation will be described later. As shown in FIG. 2, the assessment item may be directly input to the first calculation means 12 using the input means 17 such as a keyboard without using the assessment database 8. In particular, it is often easier for the inspector to determine the current items such as the accumulated mileage and the appearance at the time of the assessment according to the appearance and the like at the site.

The second calculating means 13 calculates a maintenance state evaluation value based on the contents of the maintenance state database 9. The details of the operation will be described later. The third calculating means 14 calculates a usage evaluation value based on the contents of the usage database 10. The details of the operation will be described later. The fourth calculating means 15 calculates the assessed price from the basic evaluation value, the maintenance status evaluation value and the usage status evaluation value. Although the first to fourth calculation means are separately described, they can be constituted by one computer or the like. The display means 16 is composed of, for example, a liquid crystal display device, and displays an evaluation price of the calculation result, a basic evaluation value in the middle, a maintenance status evaluation value, a use status evaluation value and the like.

Next, FIG. 3 is a flowchart showing the arithmetic processing in the present invention. In FIG. 3, step S
In step 1, data of an assessment item is input from the assessment database 8, and a basic evaluation value is calculated in step S2. The calculation of the basic evaluation value is, as described in an example described later, a maker name (eg, Nissan), a vehicle type (eg, Sunny), a grade (eg, super saloon), a year model (eg, late 1998), Basic points determined in advance according to the vehicle-specific items such as type (eg, passenger car), a color-added point (eg, 0 for white), and an optional point (eg, +20000 for a navigation device) , And a point according to the vehicle condition such as the appearance (eg, +20000 when the degree is good) is added to calculate the overall basic evaluation value.

Next, in step S3, maintenance status data and maintenance status basic data (standard values serving as determination criteria) are input from the maintenance status database 9. Step S
In step 4, it is determined whether or not there is maintenance status data information. In the case of "no information" (for example, when the vehicle is near a new car and the first maintenance deadline has not yet been reached), the process immediately proceeds to step S6. If "information exists", a maintenance status evaluation value is calculated using the data in step S5.

Next, in step S6, the use situation data and the use situation basic data (the standard value as the basis of the decision) are inputted from the use situation database 10. In step S7, it is determined whether or not there is use status data information. If the information is "no information" (for example, the vehicle is almost unused because it is close to a new car), the process immediately proceeds to step S9.
If "information exists", a use state evaluation value is calculated using the data in step S8.

Next, in step S9, an assessment price is calculated from the above-described basic evaluation value, maintenance status evaluation value and use status evaluation value. This calculation is performed, for example, by adding a maintenance status evaluation value that takes a positive or negative value and a usage status evaluation value to the basic evaluation value, as described in the following example. Note that the maintenance status evaluation value and the usage status evaluation value may be values obtained by multiplying a value obtained by calculation by a vehicle type coefficient. The vehicle type coefficient is a coefficient depending on the type of vehicle such as a passenger car, a wagon, an RV, a van, and the like. For example, a passenger car or a wagon has a large coefficient value, and an RV or a van that is easily worn out has a small value.

Therefore, the calculation in step S9 is, for example, as follows. Assessed price = basic evaluation value + (maintenance evaluation value x vehicle type coefficient)
+ (Use situation evaluation value x vehicle type coefficient).

The calculation of the maintenance status evaluation value in step S5 and the calculation of the usage status evaluation value in step S8 will be described below. FIG. 4 is a flowchart showing the calculation contents of the maintenance status evaluation value in step S5 in FIG. In FIG. 4, first, in step S10, various frequencies such as replacement of consumables, inspection, maintenance, accident, and breakdown, and the accumulated traveling distance and time at that time are calculated. Next, in step S11, an addition / subtraction point due to replacement of consumables such as tires and oil is calculated. In this case, using the result of step S10, if the tires, oils, etc. are replaced more frequently than the standard values (may be a predetermined range instead of a single value) in the basic maintenance data, the points, the period and the running If the distance is longer than the standard value, it will be penalized. Next, in step S12,
Calculate the addition and subtraction points due to inspection and maintenance. This is step S1
Using the result of 0, it is determined whether or not regular inspections and maintenance have been received within the standard value of the mileage within the regular period, and if it is in the regular state, additional points, outside the period, and mileage are large. In this case, the points will be deducted. Next, in step S13, an add / drop point due to an accident or a failure is calculated. Failure is good if it is completely repaired, but it will be penalized if it cannot be completely repaired or in the case of an accident. Next, in step S14, the above-mentioned respective adjustment points are added to calculate a maintenance state evaluation value.

FIG. 5 is a flowchart showing a process of calculating data to be input to the usage database 10. In FIG. 5, in a step S15, an in-vehicle computer,
The user inputs position information and the like of a vehicle-mounted distance sensor and a navigation device. Next, in step S16, map data and weather data (weather information of the Meteorological Agency and a weather company, and outputs of vehicle temperature sensors and rainfall sensors) are input. Next, in step S17, the location of the vehicle and the weather are calculated from the input data, and in step S18, the data is input to the usage database.

Next, FIG. 6 is a flowchart showing the contents of calculation of the usage status evaluation value in step S8 in FIG. In FIG. 6, first, in step S19, various measured values and time are calculated from the contents of the input use situation database. In other words, the location and time (eg
A time on coast, B time on mountains), weather conditions and time (C time on snow, hail, hail), travel location and travel distance (X in city)
km, Ykm in mountains). Next, in step S20, an adjustment value according to the location is calculated. For example, if the time on the coast is long, the degree of damage due to salt damage is large, so the adjustment point is negative. Next, step S
At 21, an add / drop point due to weather is calculated. For example, snow,
In the case of hail, hail, etc., especially in the case of hail, there is a large adverse effect on the painting, so even a short time can be a significant negative point. Next, in step S22, an addition / subtraction point for each traveling path is calculated. For example, when the traveling distance of an urban paved road is long, the adjustment point is improved even when the entire traveling distance is large, and when the traveling distance is high on mountainous terrain, the value is negative and large. Next, in step S23, the above step S2
The calculation results at 0, 21, and 22 are added to obtain a usage evaluation value.

FIGS. 7 and 8 are tables showing the outline of each database and each evaluation value calculation and their actual examples. FIG. 7 shows an assessment database and a use situation database.
FIG. 8 shows the maintenance status database. In FIGS. 7 and 8, each basic amount of each arithmetic expression is a value appropriately set so as to conform to the actual situation for the corresponding event. In the example of FIG. 8, the evaluation value of the maintenance status of the oil change performed by the user by himself is a low value, but the self-reported value by the user is more reliable than the maintenance by a maintenance shop or the like. This is because the coefficient is set to a small value (1.0 → 0.2) assuming that the characteristics are low.

In the above description, an assessment database, a maintenance situation database, and a use situation database are provided, and a basic valuation amount, a maintenance situation valuation amount, and a use situation valuation amount are calculated, and a final assessment price is calculated from them. Although the case of calculation was described, the basic evaluation value and the maintenance status evaluation value are calculated from the assessment database and the maintenance status database without using the usage status database and the usage status evaluation value, and the final assessment price is calculated from them. It may be a method. Further, as described above, a configuration may be adopted in which some or all of the assessment items are input directly, not from the assessment database.

In the present invention, a user (owner of a vehicle) and a sales company, a maintenance company, a management company, a purchase company, an auction company, and the like access the maintenance status database and the usage status database through a network such as the Internet. Accurate assessments can be performed by sharing data on changes over time in maintenance status and usage status.
For this reason, the purchaser can reduce the unexpected risk of poor maintenance and accidents, so that purchase at a relatively high price becomes possible. Further, since the maintenance status database is made public, opaque over-maintenance and the like are not performed, so that a relatively inexpensive purchase can be made for the next purchaser. The maintenance status database and the usage status database are open to general vehicle users and owners free of charge.However, sales companies, maintenance companies, purchase companies, auction companies, etc. refer to these databases when referring to these databases. You may be made to collect the cost.

Further, by providing the used car retail database, the maintenance situation database, and the use situation database together, the contents of the used car on sale can be accurately checked, and the non-stock sales using the Internet or the like can be performed. Will also be easy to use. In addition, a used car dealer browses the maintenance status database and the usage status database, so that high-quality vehicles with good maintenance can be sold at a low cost without newly adding maintenance costs. In this case as well, the maintenance status database and the usage status database are open to general users free of charge, but a fee may be collected from a sales company or the like when referring to these databases.

Also, in the case of a net auction by an auction company, by combining the auction database, the maintenance status database, and the usage status database, it is possible to prevent maintenance problems at the time of sale. In this case as well, the maintenance status database and the usage status database are open to general users free of charge, but an auction company may collect a fee when referring to these databases.
