Description

  The present invention relates to a vehicle quality management system and a vehicle quality management method for determining validity of quality information of a used vehicle.

  Conventionally, used vehicles are traded by used auctions among used vehicle dealers. When dealing with a used vehicle, the price of the used vehicle is determined in consideration of the mileage, the presence or absence of an accident, the model, the model year, and the like.

  Here, the following evaluation method of a used vehicle is proposed by Unexamined-Japanese-Patent No. 2002-259753 (patent document 1). This evaluation method calculates the basic evaluation value from the vehicle type, grade, etc., calculates the maintenance status evaluation value from the maintenance status data, and evaluates the price of the used vehicle.

By the way, among used vehicle dealers, there are those who increase the price of used vehicles by falsifying the meter to reduce the travel distance. Therefore, there is a used vehicle information system for registering quality information (travel distance, presence / absence of accident, presence / absence of submergence, etc.) of used vehicles by an auction dealer when used vehicles are listed in the auction. This used vehicle information system can be browsed / registered by a used vehicle dealer and the like, and by browsing the registered quality information, it is possible to identify the camouflaged vehicle after registration.
JP 2002-259753 A

  However, since the used vehicle information system described above can also register used vehicle quality information even by used vehicle dealers who perform camouflage, it is possible to detect impersonation by registering quality information after performing camouflage. It can be difficult. Thus, in the above-mentioned used vehicle information system, only accurate information is not necessarily registered.

  In such a situation, a used vehicle dealer purchases a camouflaged vehicle at the auction or the like. This camouflaged vehicle will eventually be purchased by the general consumer, and the disguised trader will benefit and the general consumer will suffer damage.

  In view of the above-described conventional situation, an object of the present invention is to provide a vehicle quality management system and a vehicle quality management method that improve accuracy of quality information of used vehicles.

  In order to solve the above-mentioned problems, a vehicle quality management system according to the present invention is a vehicle quality management system that determines the legitimacy of quality information (travel distance, presence / absence of an accident, presence / absence of submersion, etc.) of a used vehicle, Regular quality information that stores quality information acquisition means for judgment used to obtain quality information for judgment input by used vehicle dealers, etc., and regular quality information for used vehicles (information on dealers, manufacturers, insurance companies, specific traders, etc.) Normal quality information acquisition means for acquiring normal quality information of the same vehicle as the determination target quality information from the information database, and the determination target quality information and the normal quality information are compared to determine the validity of the determination target quality information And a calculation means for performing the operation.

  According to the said structure, a legitimacy can be determined effectively by comparing with the regular quality information the judgment object quality information of the used vehicle which a user inputs. In addition, when using the quality information of a used vehicle that has been validated by this judgment, the accuracy of this quality information can be confirmed by proving that the system has been validated in some form. become.

  Preferably, the calculation means compares the prediction information with the determination target quality information by calculating the prediction information of the determination target quality information predicted over time from the registration of the regular quality information. As a result of the comparison, when the determination target quality information satisfies a predetermined standard, it is determined to be valid.

  According to the above configuration, it is possible to more effectively determine the legitimacy of the determination target quality information, and to find out the quality information input by a trader who skillfully disguises the quality information. Therefore, the validity of the quality information can be determined more effectively.

Preferably, the calculation means is configured to determine the validity level by quantifying the validity of the determination target quality information.
According to the above configuration, it becomes easy to manage the validity determination result of the determination target quality information, and the validity result can be effectively used by accumulating the user's validity level.

  Preferably, storage means for storing the validity level of the determination target quality information determined by the calculation means as user information of a user who has input the determination target quality information, and the calculation means includes the normal quality When the information acquisition unit cannot acquire the regular quality information, the determination target quality information input by the user within a certain standard is determined as valid.

  According to the above configuration, the determination target quality information from the legitimacy of the quality information that the user has requested for determination in the past by using the user information as a reference for determination in addition to the regular quality information of the same vehicle as the determination target quality information Therefore, it is possible to effectively determine the validity of the quality information. In addition, even if normal quality information of the same vehicle as the determination target quality information is not obtained, user information can be used as a determination criterion, so that variations of the validity determination criteria are widened, and the quality information is more effective. Can be determined.

  Preferably, a user registration database in which the user can register the quality information only for the determination target quality information that is determined to be valid by the calculation means and the user information is input by a user within a certain standard. It is further provided with a registration means for registering to the above.

  According to the above configuration, the quality information approved by the system is attached and the quality information to be judged is registered in the user registration database on behalf of the user registration database, so that Information can be increased and accuracy of quality information can be improved.

  In the present invention, the determination target quality information and the regular quality information are acquired and compared to determine the validity of the determination target quality information. As a result, it is possible to determine the validity of the quality information of the used vehicle input by the user, and when using the quality information of the used vehicle for which the validity is recognized by this determination, the system is validated in some form. Proving that it is recognized also confirms the accuracy of this quality information. Therefore, the accuracy of used vehicle quality information can be improved by using this system.

Hereinafter, a vehicle quality management system and a vehicle quality management method according to embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
FIG. 1 is a block diagram showing a vehicle quality management system connected to a network according to the first embodiment of the present invention.

  In the figure, a vehicle quality management system 1 includes a determination target quality information acquisition unit 2, a regular quality information acquisition unit 3, and a calculation unit 4, and is connected to a user terminal 5 and a regular quality information database 6 through a network 10. Has been.

  The determination target quality information acquisition unit 2 determines the determination target quality information (chassis number, model, year, driving) of the determination target used vehicle input by the user (for example, used vehicle dealer, auction trader) via the network 10. Distance, travel category, accident category, etc.) can be acquired from the user terminal 5.

  The regular quality information acquisition unit 3 can acquire regular quality information of used vehicles from the regular quality information database 6 via the network 10. Here, the regular quality information is quality information obtained from a manufacturer, a dealer, an insurance company, a reliable specific supplier, or the like. Further, the regular quality information database 6 may be a database that the vehicle quality management system 1 itself stores regular quality information obtained from information sources such as manufacturers and dealers, and is owned by the manufacturer or dealer described above. It may be a database.

In addition, although mentioned later in detail, the calculating part 4 compares said determination object quality information and regular quality information, and determines the validity of determination object quality information.
Next, FIG. 2 will be described. This figure is a flowchart showing the validity determination of the quality information by the vehicle quality management system.

  This process includes a computer having a very standard configuration, that is, as shown in FIG. 3, a CPU 11 that controls each component by executing a control program, a ROM, a RAM, a magnetic storage device, and the like. A storage unit 12 for controlling each component, a storage unit 12 used as a work area when the CPU 11 executes the control program or a storage region for various data, an input unit 13 for acquiring various data, A computer including an output unit 14 that presents various data on a display and the like and an I / F unit 15 that provides an interface function for data exchange with other devices is performed. In order to cause the computer to perform such processing, for example, a control program for causing the computer to perform the processing of the procedure shown in FIG. 2 is created and recorded on a computer-readable recording medium. The program may be read out from the recording medium by a computer and executed, and as a result, the computer functions as the vehicle quality management system 1.

  As a recording medium from which the recorded control program can be read by a computer, for example, a memory such as a RAM, a ROM, or a hard disk device provided as an internal or external accessory device in the computer, or an FD (flexible disk) Portable recording media such as MO (magneto-optical disk), CD-ROM, and DVD-ROM can be used.

  Further, the recording medium may be a storage device provided in a computer that functions as a program server and is connected to the computer via a line. In this case, a transmission signal obtained by modulating a carrier wave with a data signal representing a control program is transmitted from the program server through a line as a transmission medium, and the computer demodulates the received transmission signal to control the program. The control program can be executed by playing back.

Hereinafter, the above-described quality information validity determination will be described with reference to the flowchart of FIG.
First, the determination target quality information acquisition unit 2 acquires the determination target quality information input by the user at the user terminal 5 (S11). Next, the regular quality information acquisition unit 3 acquires the regular quality information of the same vehicle as the determination target quality information from the regular quality information database 6 (S12). When the normal quality information of the same vehicle can be acquired from the normal quality information database 6, the calculation unit 4 compares the determination target quality information with the normal quality information, and performs a validity determination (S13). For example, when the normal quality information includes an accident but the determination target quality information includes no accident, the validity determination is performed as invalid. In addition, for example, when the travel quality is 10000 km in the regular quality information, but the travel quality less than that is included in the determination target quality information, it is determined to be invalid.

  Moreover, the calculating part 4 is good to calculate prediction information from regular quality information as follows. As shown in FIG. 4, half a year later (July 1, 2005) of a used vehicle that was a travel distance of 40000 km in the regular quality information (regular quality information 1) one year ago (January 1, 2005). An example will be described in which the regular quality information (regular quality information 2) is a travel distance of 50000 km, and the travel distance is 80000 km at the time of determination six months later (January 1, 2006).

  First, a predicted distance is calculated from a set value of an allowable error range that is arbitrarily set (here, 50 to 150%). In this case, since the travel distance has increased by 10,000 km in half a year from the regular quality information 1 to the regular quality information 2, it can be predicted to be 60000 km at the time of determination after half a year. This corresponds to 100% of the allowable error range. If the allowable error range is set to 50 to 150%, the travel distance of the prediction information is 55,000 to 65000 km. Since the determination target quality information exceeds 15000 km with respect to this error tolerance range, when the validity level is set to -0.1 for every 10% outside the error tolerance range, the validity level is -1. 5 If the determination target quality information is determined on the basis of the validity level, more effective validity determination can be performed.

  In the above-described calculation of the validity level, the travel distance of the determination target quality information is greater than the travel distance of the regular quality information. Is registered in a user registration database (to be described later) that can be registered and browsed by the user, and can be performed when raising the estimated amount of the self (fake trader) over other used vehicle dealers.

  On the other hand, when the travel distance of the determination target quality information is smaller than the travel distance of the regular quality information, it is possible to determine that the determination target quality information is not valid without calculating the validity level. Further, in the above-described calculation of the validity level, the validity level is evaluated only with a minus, but if the quality information is valid, a positive evaluation may be considered.

  After the above procedure is completed, it will be described in each embodiment described later. In addition to this, for example, it is confirmed that the system 1 has validated the judgment target quality information judged to be valid. It is good to use with a guarantee.

  In the vehicle quality management system 1 according to the present embodiment, the determination target quality information and the regular quality information are acquired, and the legitimacy of the determination target quality information is determined by comparing them. As a result, it is possible to determine the validity of the quality information of the used vehicle input by the user, and when using the quality information of the used vehicle for which the validity is recognized by this determination, the system is validated in some form. Proving that it is recognized also confirms the accuracy of this quality information. Therefore, according to the vehicle quality management system 1 which concerns on this embodiment, the accuracy of the quality information of a used vehicle can be improved.

  Further, in the present embodiment, the quality information inputted by a trader who is skillfully impersonating the quality information is also legitimate by calculating the prediction information of the quality information to be judged that is predicted with the passage of time from the registration of the regular quality information. It can be recognized that it is not. Therefore, the validity of the quality information can be determined more effectively.

[Second Embodiment]
FIG. 5 is a block diagram showing a vehicle quality management system connected to a network according to the second embodiment of the present invention.

  In the figure, the vehicle quality management system 21 includes a determination target quality information acquisition unit 22, a regular quality information acquisition unit 23, a calculation unit 24, and further includes a storage unit 27, as in the first embodiment. . The vehicle quality management system 21 is connected to the user terminal 25 and the regular quality information database 26 via the network 20.

  The determination target quality information acquisition unit 22 determines the determination target quality information (chassis number, model, year, travel) of the determination target used vehicle that is input by the user (for example, used vehicle dealer, auction dealer) via the network 20. Distance, travel category, accident category, etc.) can be acquired from the user terminal 25.

  The regular quality information acquisition unit 23 can acquire regular quality information of used vehicles from the regular quality information database 26 via the network 20. Here, the regular quality information is quality information obtained from a manufacturer, a dealer, an insurance company, a reliable specific supplier, or the like. Further, the regular quality information database 26 may be a database that the vehicle quality management system 21 itself stores regular quality information obtained from a plurality of information sources such as manufacturers and dealers. It may be an owned database.

  The calculation unit 24 compares the determination target quality information with the regular quality information or user information described later, and determines the validity of the determination target quality information. Further, the storage unit 27 stores the validity level shown in FIG. 4 described in the first embodiment as a validity level (user information) for each user as shown in FIG. 7, for example.

  FIG. 6 is a flowchart showing the validity determination of the quality information by the vehicle quality management system. Also in the present embodiment, the following validity determination may be performed by a computer as shown in FIG.

  First, the determination target quality information acquisition unit 22 acquires determination target quality information input by the user at the user terminal 25 (S21). Next, the regular quality information acquisition unit 23 acquires the regular quality information of the same vehicle as the determination target quality information from the regular quality information database 26 (S22). And when the regular quality information of the same vehicle cannot be acquired from the regular quality information database 26, the user information of the user is acquired from the storage unit 27 (S23). When the normal quality information or the user information can be acquired, the calculation unit 24 determines the validity (S24). For example, in the case where there is an accident in the regular quality information, there is no accident in the determination target quality information. For example, it is determined that the determination target quality information is not valid. Further, as described in the first embodiment, the prediction information may be calculated based on the passage of time since the registration of the regular quality information. When the determination is made based on the user information, as shown in FIG. 7, for example, the validity level of the past two months is referred to, and information from a user whose validity level is minus 10 or less is recognized as valid. It is also possible not to. Further, when the determination is performed based on the user information, it is also effective to perform the validity determination by referring to the validity levels of the past several times instead of the technique of the past few months.

  Then, the storage unit 27 stores the result of the above-described legitimacy determination (legitimacy level) as user information as shown in FIG. 7, for example (S25). If neither the regular quality information nor the user information can be acquired, the name of the user who input the determination target quality information and the content of the determination target quality information may be stored as user information. Here, in the present embodiment, the procedure for acquiring the user information only when the normal quality information could not be acquired has been described. However, the normal quality information is acquired and the procedure for acquiring the user information is further used. This is an effective method because the validity can be determined from the quality information and user information and the determination target quality information.

  In the vehicle quality management system 21 according to the present embodiment, the legitimacy of the quality information that the user has requested for determination in the past by using the user information as a criterion for determination in addition to the regular quality information of the same vehicle as the determination target quality information. By judging the legitimacy of the judgment target quality information from the above, the legitimacy of the quality information can be judged effectively. In addition, even if normal quality information of the same vehicle as the determination target quality information is not obtained, user information can be used as a determination criterion, so that variations of the validity determination criteria are widened, and the quality information is more effective. Can be determined. Therefore, according to the vehicle quality management system 21 according to the present embodiment, the accuracy of the quality information of the used vehicle can be improved more effectively.

[Third Embodiment]
FIG. 8 is a block diagram showing a vehicle quality management system connected to a network according to the third embodiment of the present invention.

  In the figure, the vehicle quality management system 31 includes a determination target quality information acquisition unit 32, a regular quality information acquisition unit 33, a calculation unit 34, and a storage unit 37, as well as the registration unit 38, as in the second embodiment. It has. The vehicle quality management system 31 is connected to the user terminal 35, the regular quality information database 36, and the user registration database 39 via the network 30.

  The determination target quality information acquisition unit 32 receives the determination target quality information (vehicle stand number, model, year, driving) of the determination target used vehicle input by the user (for example, used vehicle dealer, auction dealer) via the network 30. Distance, travel classification, accident classification, etc.) can be acquired from the user terminal 35.

  The regular quality information acquisition unit 33 can acquire regular quality information of used vehicles from the regular quality information database 36 via the network 30. Here, the regular quality information is quality information obtained from a manufacturer, a dealer, an insurance company, a reliable specific supplier, or the like. Further, the regular quality information database 36 may be a database that the vehicle quality management system 31 itself stores regular quality information obtained from a plurality of information sources such as manufacturers and dealers. It may be an owned database.

  In addition, the calculating part 34 compares said determination object quality information with regular quality information or user information, and determines the validity of determination object quality information. Further, the storage unit 37 gives the past validity determination result (correctness level) of the determination target quality information, for example, by adding a point of, for example, plus 5 points to minus 5 points, as shown in FIG. And stored as a legitimacy level (user information) for each user. The registration unit 38 is connected to the user registration database 39 via the network 30. The user registration database 39 is a database in which a user can register quality information independently. Here, the quality information can be viewed or changed.

  FIG. 9 is a flowchart showing validity determination of quality information by the vehicle quality management system. Also in the present embodiment, the following validity determination may be performed by a computer as shown in FIG.

  First, the determination target quality information acquisition unit 32 acquires determination target quality information input by the user at the user terminal 35 (S31). Next, the regular quality information acquisition unit 33 acquires the regular quality information of the same vehicle as the determination target quality information from the regular quality information database 36 (S32). And when the regular quality information of the same vehicle cannot be acquired from the regular quality information database 36, the user information is acquired from the storage unit 37 (S33). When the normal quality information or the user information can be acquired, the calculation unit 34 determines the validity (S34). For example, in the case where there is an accident in the regular quality information, but there is no accident in the determination target quality information, it is determined that the determination target quality information is not valid. Further, as described in the first embodiment, the prediction information may be calculated based on the passage of time since the registration of the regular quality information.

  When the determination is made based on the user information, as shown in FIG. 7, for example, the validity level of the past two months is referred to, and information from a user whose validity level is minus 10 or less is recognized as valid. It is also possible not to. In addition, it is also effective to refer to the validity levels of the past several times and perform the validity judgment instead of the past months.

  Here, it is confirmed whether or not the quality information to be judged is valid (S35), and whether or not the validity level (user information) is a user within a certain standard (S36) and registered. The unit 38 determines whether the validity is greater than a certain standard (for example, a criterion that the quality information to be judged is information consistent with the regular quality information) and the validity level is input by a user within the certain standard. Only the target quality information is registered in the user registration database 39 on behalf of the user (S37). In this proxy registration, it is desirable to add to the above quality information that the system has registered as a proxy. Here, the user information is referred to twice for the validity determination (S34) and for the proxy registration (S37), but the user information (validity level) standard and the proxy in the validity determination (S34) The standard of user information (legitimacy level) in registration (S37) may be different.

  Next, the storage unit 37 stores the validity determination result of the determination target quality information as, for example, a validity level (user information) for each user (S38). If neither the regular quality information nor the user information can be acquired, the name of the user who input the determination target quality information and the content of the determination target quality information may be stored as user information. Also, the registration result registered on behalf of the user may be stored.

  Here, in the present embodiment as well, the procedure for acquiring user information only when normal quality information cannot be acquired in the validity determination (S34) has been described. A more effective determination can be made by obtaining quality information and further obtaining user information.

  In the vehicle quality management system 31 according to the present embodiment, the determination target quality information determined to be legitimate is registered in the user registration database 39 as a proxy. Thereby, legitimate quality information can be increased in the user registration database 39, and the accuracy of quality information can be improved. Further, the quality information approved by the system 31 is added and the judgment target quality information is registered in the user registration database 39 as a proxy to increase the more reliable quality information in the user registration database 39. , Can improve the accuracy of quality information effectively.
