DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of a vehicle-mounted device management system according to the present invention. This in-vehicle device management system includes an in-vehicle device management device 10 fixedly installed in a service center. This in-vehicle device management device 10
Has an input operation device 11 such as a keyboard and a mouse, a computer 12, a display 13, and a wireless device 14.

The computer 12 activates a web browser (hereinafter referred to as a service-side web browser) by an input operation of the input operation device 11 and executes the web browser according to the flowchart shown in FIG. During this execution, the computer 12 performs a process of transmitting a CGI command via the wireless device 14 and a process of receiving, via the wireless device 14, management data relating to in-vehicle devices, which will be described later, and displaying it on the display 13. The service-side web browser is stored in advance in the ROM of the computer 12 as software.

The wireless device 14 transmits the transmission data from the computer 12 to a later-described wireless device 21 via the public line P, and receives the later-described transmission data from the wireless device 21 and inputs the same to the computer 12.

The in-vehicle device management system includes an in-vehicle device 20 mounted on a delivery truck on the user side. The in-vehicle device 20 includes a wireless device 21, a web server 22 as a computer, and an in-vehicle device 23. It consists of. In the present embodiment, the in-vehicle device 23 includes a navigator 23a, a telephone 23b, a barcode reader 23c,
It comprises a computer 23d, a display 23e connected to the computer, and various electronic control units 23f (hereinafter, ECU 23f) such as a fuel injection control unit.

The web server 22 executes a web browser (hereinafter, referred to as a user-side web browser) according to the flowchart shown in FIG. 3, and during this execution, a failure diagnosis program (hereinafter, CGI) accompanying the reception of the CGI command. A process for diagnosing the presence or absence of an abnormality in the vehicle-mounted device 23 is performed by executing the program. The user-side web browser is stored in advance in the ROM of the web server 22 as software.

The wireless device 21 receives a signal from the wireless device 14 via the public line P.
Is transmitted to the web server 22 and the transmission data from the web server 22 is transmitted to the wireless device 14 via the public line P.

In this embodiment configured as described above, when an abnormality of the on-vehicle equipment 23 occurs during delivery by the delivery truck, when the occupant of the delivery truck reports the occurrence of the abnormality to the service center by telephone, the service On the center side, a service person performs a start operation of the service side web browser by the input operation device 11 in the in-vehicle device management device 10. On the other hand, the web server 22 executes the user-side web browser according to the flowchart of FIG. 3, and repeats the determination of NO in Step 40.

In such a state, the computer 12
Executes the service-side web browser according to the flowchart of FIG. 2, and in step 30, performs a CGI command transmission process. Then, the wireless device 14 sets the CG
The I command is received from the computer 12 and transmitted to the wireless device 21 of the delivery truck through the public line P.

When the transmitted CGI command is received by the wireless device 21 and input to the web server 22, the web server 22 determines YES in step 40, and determines in step 41 that the CGI program Execute In the execution of the CGI program, the presence or absence of an abnormality in the vehicle-mounted device 23 is diagnosed. Then, the diagnosis result is used as diagnosis data in step 42.
Is transmitted from the web server 22 to the in-vehicle device management device 10 via the wireless device 21 and the public line P.

Along with this, in the on-vehicle equipment management device 10, the computer 12 receives the diagnostic data via the wireless device 14, determines YES in step 31, and receives the diagnostic data in step 32. Then step 3
At step 3, the received data is displayed. Along with this, the display 13 displays data by the display processing. At this time, the display 13 displays the presence / absence of each abnormality such as the navigator 23a of the in-vehicle device 23 together with the cause of each abnormality.

Thus, the service person can use the onboard equipment 2
It is possible to reliably ascertain which of the devices 3 is abnormal due to what cause, without having to go to the site of the delivery truck and staying at the service center. As a result, the serviceman can surely prepare measures for eliminating the abnormality of the vehicle-mounted device while staying at the service center, and then go to the site where the delivery truck is located. Accordingly, the serviceman can quickly and accurately repair equipment such as the navigator 23a having an abnormality among the in-vehicle equipment, and does not hinder the work of the crew of the delivery truck.

The above-described operation and effect can be obtained by including the web server 22 in the on-board device 20 of the delivery truck, and activating the service-side web browser by the computer 12 in the on-board equipment management device 10 of the service center by the computer 12. This can be achieved by remotely controlling the web server.

In practicing the present invention, the present invention is applied not only to the on-board equipment of a delivery truck but also between the on-board equipment of various vehicles such as passenger cars and buses and the on-board equipment management apparatus of a service center. Is also good.

In implementing the present invention, the radio 14
Instead, a wired machine (wired circuit) such as a public line may be adopted.
