Abstract

A used car information search method of inputting a search condition containing car type information for specifying a type of a used car, searching for used car data coincident with the search condition from a used car database containing the car type information and price information, and outputting the searched used car data. This method comprises a step of researching the price information in all records of used car data coincident with the car type information contained in the search condition, and creating price research information, and a step of transmitting the used car data coincident with the search condition and the price research information for displaying them to a user. This scheme enables an efficient search for the used car information regardless of how much a prospective purchaser is skilled at searching.

Claims

1. A used car information search method of inputting a search condition containing car type information for specifying a type of a used car, searching for used car data coincident with the search condition from a used car database containing the car type information and price information, and outputting the searched used car data, said method comprising:

a step of researching the price information in all records of used car data coincident with the car type information contained in the search condition, and creating price research information; and

a step of transmitting the used car data coincident with the search condition and the price research information for displaying them to a user.

2. A used car information search method comprising:

a step of extracting all records of first used car data coincident with search condition information for specifying a type of a used car;

a step of extracting, as price zone information, a minimum price and a maximum price mapping to the search condition information for specifying the type of the used car on the basis of the first used car data;

a step of extracting second used car data coincident with other items of search condition information designated by a user on the basis of the first used car data; and

a step of transmitting the price zone information and the second used car data for displaying them to the user.

3. A used car information search method according to claim 2, wherein the search condition information for specifying the type of the used car is at least one of a maker name and a car name.

4. A used car information search method according to claim 2, wherein said other items of search condition information contain at least one of a price, a model year, and a mileage.

5. A used car information search method according to claim 2, further comprising:

a step of creating screen display data based on the second used car data and input-indicating information for re-searching in a way that sets the price-related search condition information as a selection item; and

a step of transmitting the created screen display data for displaying the same data to the user.

6. A used car information search method according to claim 5, further comprising a step of judging whether an extraction count of the second used car data is equal to or larger than a predetermined value and enabling, when said extraction count is smaller than the predetermined value, the screen display data to be created.

7. A used car information search method according to claim 2, further comprising:

a step of obtaining a registration count per price zone on the basis of the first used car data; and

a step of transmitting the registration count per price zone for displaying the registration count to the user.

8. A used car information search program of inputting a search condition containing car type information for specifying a type of a used car, searching for used car data coincident with the search condition from a used car database containing the car type information and price information, and outputting the searched used car data, said program comprising:

a step of researching the price information in all records of used car data coincident with the car type information contained in the search condition, and creating price research information; and

a step of transmitting the used car data coincident with the search condition and the price research information for displaying them to a user.

9. A used car information search program comprising:

a step of extracting all records of first used car data coincident with search condition information for specifying a type of a used car;

a step of extracting, as price zone information, a minimum price and a maximum price mapping to the search condition information for specifying the type of the used car on the basis of the first used car data;

a step of extracting second used car data coincident with other items of search condition information designated by a user on the basis of the first used car data; and

a step of transmitting the price zone information and the second used car data for displaying them to the user.

10. A used car information search program according to claim 9, further comprising:

a step of creating screen display data based on the second used car data and input indicating information for re-searching in a way that sets the price-related search condition information as a selection item; and

a step of transmitting the created screen display data for displaying the same data to the user.

11. A used car information search program according to claim 10, further comprising a step of judging whether an extraction count of the second used car data is equal to or larger than a predetermined value and enabling, when smaller than the predetermined value, the screen display data to be created.

12. A used car information search program according to claim 9, further comprising:

a step of obtaining a registration count per price zone on the basis of the first used car data; and

a step of transmitting the registration count per price zone for displaying the registration count to the user.

13. A used car information search device for inputting a search condition containing car type information for specifying a type of a used car, searching for used car data coincident with the search condition from a used car database containing the car type information and price information, and outputting the searched used car data, said device comprising:

price researching means for researching the price information in all records of used car data coincident with the car type information contained in the search condition, and creating price research information; and

transmitting means for transmitting the used car data coincident with the search condition and the price research information for displaying them to a user.

14. A used car information search device comprising:

first extracting means for extracting all records of first used car data coincident with search condition information for specifying a type of a used car;

second extracting means for extracting, as price zone information, a minimum price and a maximum price mapping to the search condition information for specifying the type of the used car on the basis of the first used car data;

third extracting means for extracting second used car data coincident with other items of search condition information designated by a user on the basis of the first used car data; and

transmitting means for transmitting the price zone information and the second used car data for displaying them to the user.

15. A used car information search device according to claim 14, wherein the search condition information for specifying the type of the used car is at least one of a maker name and a car name.

16. A used car information search device according to claim 14, wherein other items of search condition information contain at least one of a price, a model year and a mileage.

17. A used car information search device according to claim 14, further comprising:

creating means for creating screen display data based on the second used car data and input indicating information for re-searching in a way that sets the price-related search condition information as a selection item,

wherein said transmitting means transmits the created screen display data for displaying the same data to the user.

18. A used car information search device according to claim 17, further comprising judging means for judging whether an extraction count of the second used car data is equal to or larger than a predetermined value and enabling, when smaller than the predetermined value, the screen display data to be created.

19. A used car information search device according to claim 14, further comprising calculating means for obtaining a registration count per price zone on the basis of the first used car data,

wherein said transmitting means transmits the registration count per price zone for displaying this registration count to the user.
