  The HDD 99 has an exchange record database 99c, which corresponds to the exchange record storage means in the present invention. As shown in FIG. 6, the exchange record database 99c assigns device identification numbers to a plurality of navigation devices 1, and parts such as “engine oil” and “oil filter” are assigned to each of the navigation devices 1. For each time, store values such as the “replacement period”, which is the period required from the previous replacement, the “replacement distance”, which is the distance the vehicle has traveled within the period, and the “replacement date”, which is the date of replacement. Yes. In addition, although not shown in the figure, “accumulated travel distance” at the time of replacement, “vehicle type” of the vehicle, “type of part” such as manufacturer and model number of the replaced part, and the like are also stored.

  Further, the parts list database 99d stores an input item list to be output to the display device 51 next when one part in the parts list is selected by the input unit of the navigation device 1 ( (See FIG. 5). The input item list corresponds to the items stored in the area related to each part by the replacement record database 99c, and can be input by an input means such as the operation switch group 41 of the navigation device 1. The item “exchange date” can be omitted because it can be obtained from the RTC 16 of the control circuit 10 as described above.

(4) Processing Performed by Navigation Device 1 and Maintenance Information Server 100 Next, operations of the navigation device 1 and the maintenance information server 100 described above will be described with reference to FIGS. 8 and 9 are flowcharts showing the process of the navigation program 12p executed by the CPU 11 of the navigation apparatus 1 and the process of the maintenance information server program 99b executed by the CPU 91 of the maintenance information server 100. The flowchart of FIG. 8 shows an exchange record information registration process for registering vehicle part exchange record information from the navigation device 1 in the exchange record database 99c of the maintenance information server 100. Further, the flowchart of FIG. 9 shows a component replacement recommendation process that the maintenance information server 100 performs on the navigation device 1 when the recommended next replacement comes.

(4-1) Exchange Record Information Registration Process The exchange record information registration process in FIG. 8 will be described. When the user of the vehicle on which the navigation device 1 is mounted exchanges vehicle parts, the replacement record information is registered in the maintenance information server 100. That is, first, when the CPU 11 of the navigation device 1 detects that the user has requested a replacement part list request by the input means 41 or the like (step S11), the CPU 11 of the navigation apparatus 1 transmits the replacement part list request from the mobile phone 62 to the maintenance information server 100. (Step S12).

  When the CPU 91 of the maintenance information server 100 detects the reception of the replacement parts list request from the navigation device 1 (step S21), the CPU 91 reads the parts list stored in the parts list database 99d and sends the parts list from the network control unit 96 to the navigation device 1. Transmit (step S22). Then, when the CPU 11 of the navigation device 1 detects that the parts list has been received from the maintenance information server 100 (step S13), the parts list is displayed on the screen of the display device 51 as shown in FIG. 4 (step S14). .

  The parts list has a touch switch in the lower right corner of the screen. The user operates the “up scroll” key or “down scroll” key to move the cursor to the relevant part and select it by operating the “decision” key. Do. Thereafter, when the CPU 11 of the navigation device 1 detects that a part has been selected (step S15), it sends a part selection notification from the mobile phone 62 to the maintenance information server 100 (step S16). When the CPU 91 of the maintenance information server 100 detects the reception of the part selection notification (step S23), it reads out the input item list stored in the parts list database 99d and transmits it to the navigation device 1 from the network control unit 96 (step S24). ). Then, when the CPU 11 of the navigation device 1 detects that the input item list has been received from the maintenance information server 100 (step S17), the input item list is displayed on the screen of the display device 51 as shown in FIG. 5 (step S17). S18).

  The input item list has input fields for replacement record information such as part replacement information (replacement date, replacement period, replacement distance, part type, etc.) and vehicle information (cumulative mileage, etc.) at the time of replacement. The user inputs the replacement record information in the input field using an input means such as the operation switch group 41. As described above, the replacement date can be acquired by the RTC 16 of the control unit 10. When the CPU 11 detects that the exchange record information is input and the “send” key is operated (step S19), the CPU 11 transmits the exchange information from the mobile phone 62 to the maintenance information server 100 (step S20).

  In step S19, when the CPU 11 detects that the input item list has not been input as a required input item, a screen for prompting input again is displayed (not shown). Here, regarding the “exchange period” and “exchange distance” in the exchange record information, as will be described later, if the date and the total travel distance at the previous exchange are already stored in the exchange information database 99c, the maintenance information server Since it can be calculated on the 100 side, it does not have to be an essential input item.

  When the CPU 91 of the maintenance information server 100 detects that the exchange record information has been received from the navigation device 1 (step S25), it stores the received exchange record information in the exchange record database 99c (step S28). If necessary, the replacement period and replacement distance are calculated. That is, when the date and the total travel distance at the time of the previous replacement are already stored in the replacement information database 99c, it is determined that the replacement period and the replacement distance need to be calculated (step S26) and received from the navigation device 1. The replacement period and replacement distance are calculated by comparing the date and cumulative travel distance of the current part replacement included in the replacement record information with the date and cumulative travel distance of the previous replacement stored in the replacement information database 99c. (Step S27). Even if the exchange period and the exchange distance are included in the exchange record information received from the navigation device 1, if the date and the accumulated travel distance at the previous exchange are already stored in the exchange information database 99c, Since it is possible to obtain more accurate data when the CPU 91 of the maintenance information server 100 calculates the replacement period and the replacement distance, the calculated result is adopted.

  Thereafter, the CPU 91 of the maintenance information server 100 stores the replacement record information in the replacement information database 99c (step S28). Thus, the exchange record information registration process is completed. When the navigation device 1 registers the exchange record information in the exchange information database 99c for the first time, the CPU 91 of the maintenance information server 100 gives a new device identification number to the navigation device 1, and then the device identification number. The exchange record information is stored in this area. That is, for example, as shown in FIG. 6, device identification numbers “0001” to “0006” are assigned to the exchange information database 99c for the other six navigation devices before this, and exchange record information is stored. In the case where it is assumed, the CPU 91 of the maintenance information server 100 gives the next device identification number “0007” to the navigation device 1 that transmits the replacement record information for the first time, and exchanges the received replacement record information. It is stored in the area of the device identification number “0007” in the database 99c (see FIG. 6). On the other hand, if the navigation device 1 that transmits the replacement record information previously registered the replacement record information in the replacement record database 99c and already has the device identification number, the CPU 91 of the maintenance information server 100 has received it. The replacement record information is overwritten in the corresponding device identification number area.

(4-2) Statistics of Replacement Record Information and Calculation at Next Recommended Replacement Next, statistics of replacement record information and calculation at the next recommended replacement by the CPU 91 of the maintenance information server 100 will be described. The maintenance information server program 99b includes a program that causes the CPU 91 of the maintenance information server 100 to periodically perform the following processing. The CPU 91 reads “exchange period” and “exchange distance” from the exchange record information stored in the exchange record database 99c, collects the statistics, and stores the average value for each component in the average value of the exchange record database 99c. It memorize | stores in an area | region (refer FIG. 6). Then, the obtained “average replacement period” is added to the “replacement date” of each device identification number (navigation device 1), and the value is further stored in the replacement record database 99c as the next recommended replacement (see FIG. 6). ). As a calculation method at the next recommended replacement, for example, a statistical value such as an average value + σ or an average value + 3σ considering not only the average value but also the standard deviation σ is used, and the value is added to the “exchange date”. It is also possible to adopt a method such as the next recommended replacement.

  Further, the statistics of the replacement record information can be individually performed according to, for example, the type of replacement part or the type of vehicle. That is, since the replacement record information includes the type of replacement part (manufacturer name, model number, etc.) and the type of vehicle, as shown in FIG. It can be taken separately (for example, engine oil of the type “A”). Then, the average value for each type of part is stored in the average value area of the replacement record database 99c, and added to the “replacement date” of the corresponding device identification number (navigation device 1). And As a result, more reliable information can be provided to the user.

(4-3) Component Replacement Recommendation Processing Next, the component replacement recommendation processing of FIG. 9 will be described. The maintenance information server program 99b includes a program for causing the CPU 91 of the maintenance information server 100 to periodically determine whether or not the next recommended replacement time has arrived for each component of each navigation device 1. If there is a part for which the next recommended replacement time has arrived (step S41), the CPU 91 causes the network control unit 96 to transmit the part replacement recommendation information to the navigation device 1 (step S42). When the CPU 11 of the navigation device 1 detects the reception of the exchange recommendation information (step S31), it outputs it to the screen of the display device 51 as shown in FIG. 7 (step S32).

  Specifically, if the recommended next replacement target is the engine oil of the device identification number 0007, the CPU 91 of the maintenance information server 100 determines the average value of the replacement period and replacement distance and the final replacement from the replacement record database 99c. The replacement date and the total travel distance at the time are read out and included in the replacement recommendation information and transmitted from the network control unit 96 to the navigation device 1 corresponding to the device identification number 0007. When the CPU 11 of the navigation device 1 receives the replacement recommendation information, the CPU 11 outputs a message prompting the replacement of the parts to the display device 51 as shown in FIG. 7, and the average value of the replacement period and the replacement distance. The date of replacement at the time of the last replacement and the total travel distance are output. Thus, by displaying the average value of the replacement period and the replacement distance, it is possible to make a component replacement recommendation with higher reliability for the user.

  Further, the replacement recommendation information in the above processing can display the average value of the replacement period and the replacement distance for the type of the component, for example, the engine oil of the type “A” (see FIG. 7). In other words, as described above, the replacement record database 99c can store the replacement period and the average value of the replacement distance for each type of part, so that the CPU 91 of the maintenance information server 100 can store the replacement date and the last replacement time. Along with the accumulated travel distance, the type of the part related to the corresponding navigation device 1, the replacement period and the average value of the replacement distance related to the type of the part are read from the replacement record database 99c and included in the replacement recommendation information. Then, as shown in FIG. 7, the CPU 11 of the navigation device 1 outputs to the display device 51 the average value of the part type (for example, engine oil “A”) and the replacement period and replacement distance related to the part type. . As a result, the user can obtain average replacement information about the parts used by the user.

  The terminal device 200 can be installed under a parts replacement company such as a card dealer, motors, or a repair shop. In other words, there are not many cases where parts are replaced by individuals. In practice, it is common to request parts replacement from a car dealer, motors, repair shop, etc. Each time, the trader registers the exchange record information on the terminal device 200 on behalf of the user. This saves the user trouble and allows the maintenance information server 100 to collect detailed and accurate replacement record information that cannot be expected by user input. In addition, since the component replacement recommendation is made directly to the user's navigation device 1, the user can obtain a more reliable component replacement recommendation without any effort.

  The terminal device 200 will be described. FIG. 11 is a block diagram illustrating the overall configuration of the terminal device 200.

The network control unit 86 controls communication with the maintenance information server 100 through the network.

  The HDD 89 stores an operating system program (hereinafter referred to as OS) 89a and an exchange record registration program 89b. The exchange record registration program 89b operates in such a manner that the registration program work memory 83b secured in the RAM 83 on the OS 89a is used as a work area. In the RAM 83, a work memory 83a of the OS 89a is also formed. With this configuration, the terminal device 200 functions as a terminal device according to the present invention when the exchange recording registration program 89b is started by the CPU 81.

  The operation of the terminal device 200 described above will be described. The CPU 81 of the terminal device 200 performs exchange record information registration processing by executing the exchange record registration program 89b. The exchange record information registration process is the same as the exchange record information registration process according to the first embodiment of FIG. 9 except that the navigation device 1 is replaced with the terminal device 200 according to the present embodiment. Therefore, the parts list shown in FIG. 4 and the registered item list shown in FIG. 5 are displayed on the screen of the display device 88 of the terminal device 200. Each list is obtained by operating the operation input unit 87 such as a keyboard and a mouse. Input is made. When the exchange record information is registered by the terminal device 200 in this way, the subsequent processing is the same as in the first embodiment. That is, the maintenance information server 100 calculates the average value of the replacement period and the replacement distance and calculates the recommended next replacement time, and transmits the replacement recommendation information to the corresponding navigation device 1 when the recommended next replacement time arrives. To do.
