Description:
CROSS REFERENCE TO RELATED APPLICATION  
     [0001] This application is based on and incorporates herein by reference Japanese Patent Application No. 2000-208836 filed on Jul. 10, 2000. 
    
    
     
       BACKGROUND OF THE INVENTION  
       [0002] The present invention relates to a method and apparatus for supplying vehicle information such as maintenance and parts.  
       [0003] Vehicles must be inspected regularly for safety and other reasons. Vehicle dealers inform by direct mails vehicle owners when the vehicles should be inspected, as a maintenance time management. However, the content of this information is limited. Thus each owner has to determine when various condition of the vehicle should be inspected and repaired, and when oil, filters and other parts should be replaced.  
       [0004] Service shops other than the dealers also provide vehicle users with parts information regarding respective vehicles by direct mails and advertisements on newspapers and the like. However, these parts information include parts information other than that of a specific vehicle. Therefore, each owner has to select only a part of information that relates to the specific vehicle.  
       SUMMARY OF THE INVENTION  
       [0005] It is therefore an object of the present invention to provide a method and apparatus which is capable of supplying vehicle information such as maintenance management information and parts information specific to each vehicle.  
       [0006] According to the present invention, a vehicle information supply system comprises user terminals and an information center connected to each other through a communication network. The information center stores maintenance management information of vehicles in its user-divided database in response to inputs of vehicle owners, and information regarding maintenance works provided by advertisement requesters in its advertisement requestor-divided database in response to requests from the advertisement requestors. The information center links the stored maintenance management information and the stored maintenance work information and extracts a maintenance work which is required by a user for a vehicle and corresponds to the required maintenance work. The information center transmits a message to a user terminal of the user to notify the time of next regular vehicle inspection along with information about an advertisement requester which provides the extracted maintenance work.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
     [0012] Referring first to FIG. 1, an information supply system has an information center  1 , and a plurality of information terminals (clients) that is used as user terminals by respective users, specifically vehicle owners. The information terminals  2  are connected to each other through a communication network  3 .  
     [0013] The information center  1  is an apparatus that is used by information providers for providing respective services. It has a user-divided database (first storage unit)  1   a  for storing private information regarding each user, an advertisement requester-divided database (second storage unit)  1   b  for storing information of advertisement requesters regarding vehicles, a communication server  1   c  and an information processing server  1   d.    
     [0014] The information center  1  may be comprised of a personal computer, workstation or the like, and has storage medium such as a hard disk that stores a program for executing the information supply as described below. This program is installed in the storage medium of the information center  1  from an external storage medium such as a CD-ROM.  
     [0015] The user terminal  2  is of a type that is capable of transmitting and receiving various information to and from the information center  1  through the communication network  3 . The user terminal  2  may be a personal computer at home, a cellular phone carried by a person or a navigation system mounted in a vehicle for a travel guidance.  
     [0016] The communication network  4  may be an open-type network such as INTERNET, a local network (LAN) or a personal computer communication.  
     [0017] In this information supply system, the information stored in the user-divided database  1   a  and advertisement requestor-divided database  1   b  are constructed to be updated by the information processing server  1   d  from time to time.  
     [0018] The user-divided database  1   a  has user addresses specific to respective users, and the private information of each user is stored in the corresponding user address. The private information includes maintenance management information such as an inspection time and oil exchange time of a vehicle of each user, preference information regarding optional parts such as tires and audio devices used in the vehicle of each user, and the like.  
     [0019] The advertisement requestor-divided database  1   b  has requester addresses specific to respective advertisement requesters who concluded agreements with the information provider, and the private information of each requester is stored in the corresponding requestor address. The private information includes services provided by each advertiser requester. Such services include repair shops which provide vehicle inspection work, specialized shops which sell vehicle parts, mass retailers which not only sell vehicle parts but also provide oil exchange work, and the like. These information are stored by classifying types of advertisement requesters.  
     [0020] The information of the repair shop specifies what maintenance work (vehicle inspection, body fixing repair, and the like). The information of the specialized shop specifies types and prices of optional parts, and the like. The information of the mass retailer specifies both of the maintenance work and the parts.  
     [0021] Upon an access request from a user or an advertisement requester, the server  1   c  checks such an access requestor based on the identification code (ID) of the user or the advertisement requestor. The server  1   c  connects the information center  1  and the corresponding user terminal  2  after completing the recognition of such an access requester.  
     [0022] The information processing server  1   d  transmits to the corresponding user terminal  2  a message or notification indicative of the next maintenance time in the maintenance management information stored in the user-divided database  1   b.  For instance, the server  1   d  transmits to the user terminal  2  the information regarding repair shops available for vehicle inspection among the advertisement requesters, in addition to the inspection time one month before an expiration of valid vehicle license. Thus, the user is enabled to manage maintenance of his or her vehicle by receiving necessary information regarding inspection time and available repair shops. Further, the repair shops are enabled to provide respective services to users and get compensation for the inspection and repair work.  
     [0023] The information processing server  1   d  links the user-divided database  1   a  and the advertisement requestor  1   b,  and transmits the information that are coincides each other between the databases  1   a  and  1   b.  That is, the server  1   d  compares the preference information, e.g., optional parts used in the vehicle and interested parts of a user, stored in the user-divided database  1   a  is compared with on-sale parts of the advertisement requestor stored in the advertisement requestor-divided database  1   b,  and transmits to the user terminal  2  parts information which corresponds to the preference of the user.  
     [0024] The above information supply processing is described in further detail with reference to FIGS. 2A and 2B. It is assumed in the following description that information providers conclude a contract with advertisement requesters and store private information of each advertisement requester in the advertisement requestor-divided database  1   b.    
     [0025] The information provider starts its vehicle-related information supply service such as maintenance management and parts information supply of vehicles by the use of the information center  1 . This service may be started by setting up a home page on the INTERNET (step  21 ).  
     [0026] When a user connects his/her user terminal  2  to the information center  1  (step  11 ), the information center  1  transmits data input screen to such a user terminal  2  so that the user terminal  2  displays the data input screen as shown in FIG. 3. This data input screen has various input items as the maintenance management information and preference information. These items are, for example, user&#39;s name, user&#39;s address, user&#39;s phone number, user&#39;s car, year of purchase, optional parts installed, after-market parts installed after purchase, last oil exchange and the like. The user inputs various required data regarding these items and transmits the input data to the information center  1 . Thus, the user completes data input and registration (step  12 ).  
     [0027] The information center  1  checks at step  22  whether the required data have been input and registered (step  22 ). If the data registration has been completed (YES), the information center  1  registers or stores in the corresponding address of the user-divided database  1   a  the private information (maintenance management information and preference information) which the user transmitted (step  23 ).  
     [0028] In the information center  1 , the information processing server  1   d  links the user-diviede database  1   a  and the advertisement requestor-divided database  1   b  (step  24 ) that have corresponding data. That is, the server  1   d  checks for data which correspond between stored data of the databases  11   a  and  1   b  based on the preference information of the user, because the registered data includes the user&#39;s preference. The server  1   d  thus extracts data which correspond to each other. For instance, if information regarding optional parts or interested parts which the user uses or has interests are registered in the user-divided database  1   a , a link is made to a parts-seller part of the advertisement requestor-divided database  1   b  which stores information of specialized shop or mass retailer having such optional parts or interested parts.  
     [0029] The information center  1  then transmits to the user terminal  2  the extracted parts information as well as the advertisement of the specialized shop and the mass retailer which have such parts (step  25 ). The user terminal  2  thus displays the parts information and the advertisement transmitted from the information center  1  (step  13 ), so that the user is enabled to readily find a shop which sells the optional parts and the interested parts and the shop is enabled to attract a new client.  
     [0030] The information processing server  1   d  further checks whether the registered maintenance management information of the user corresponds to maintenance contents of the advertisement requesters to extract corresponding data. For instance, because the inspection time can be specified from the registered data of year of purchase, a link is made to a part of repair shops and mass retailers registered in the advertisement requestor-divided database  1   b  to extract such shops which provide a regular vehicle inspection work. That is, the server  1   d  checks whether it is a vehicle maintenance time for the regular inspection and oil exchange (step  26 ). For instance, the regular inspection time may be checked whether the present license expires one month later, and the oil exchange time may be checked whether more than six months have passed after the last oil exchange. If it is the maintenance time (YES), the information center  1  transmits to the user terminal  2  the maintenance time information as well as the repair shop or mass retailer information (step  27 ).  
     [0031] Thus the user terminal  2  receives and displays the transmitted information (step  14 ) so that the user is enabled to manage his/her vehicle maintenance time and find a repair shop readily. It is preferred that the user inputs data indicating the completion of the vehicle maintenance work thereby to enable the information provider may manage demand of vehicle maintenance work.  
     [0032] In the above embodiment, it is preferred that the maintenance information is provided not only visually but also audibly, because the maintenance information is generally more important than the parts information and the like. This distinction between the visual information and the audible information may be defined by weighing various information with different importance. The maintenance information may be provided to the user repeatedly until the completion of the maintenance work is reported from the user or the repair shop. The maintenance information may be provided through a plurality of means, an electronic mail, a post mail, a telephone call.  
     [0033] It is also preferred that the information regarding repair shops, specialized shops and mass retailers are transmitted with respective location information such as location maps. Particularly when the user terminal  2  is a navigation system, the location of such shops can be indicated on the map of the navigation system.  
     [0034] It is also possible to store parts information of advertisement requesters in the advertisement requestor-divided database  1   b  for each vehicle model so that the information center  1  can readily link the vehicle information of the user in the database  1   a  with relevant information in the database  1   b  by specifying the vehicle model. The advertisement requesters may advertise respective shops and parts in place of asking the information provider to advertise the shops and parts on behalf of the advertisement requesters.  
     [0035] The present invention may be implemented in many other ways without departing from the spirit of the invention.
