Also in this embodiment, by executing the same connection processing and collection processing as in the first and second embodiments, it is possible to prevent the center server 50 from failing to collect vehicle information.

[remarks]
Note that the various processes executed by the CPU 20A and the CPU 30A by reading the software (program) in the above embodiment may be executed by various processors other than the CPU. The processor in this case is a PLD (Programmable Logic Device) whose circuit configuration can be changed after manufacturing such as an FPGA (Field-Programmable Gate Array), and an ASIC (Application Specific Integrated Circuit) for executing specific processing. A dedicated electric circuit or the like, which is a processor having a specially designed circuit configuration, is exemplified. Further, each of the processes described above may be executed by one of these various processors, or by a combination of two or more processors of the same or different type (for example, multiple FPGAs, and a combination of a CPU and an FPGA). combination, etc.). More specifically, the hardware structure of these various processors is an electric circuit in which circuit elements such as semiconductor elements are combined.

Further, in the above embodiments, each program has been described as being pre-stored (installed) in a computer-readable non-temporary recording medium. For example, the collection program in the vehicle-mounted device 20 is pre-stored in the ROM 20B, and the processing program 100 in the data logger 30 is pre-stored in the ROM 30B. However, not limited to this, each program is recorded on non-temporary recording media such as CD-ROM (Compact Disc Read Only Memory), DVD-ROM (Digital Versatile Disc Read Only Memory), and USB (Universal Serial Bus) memory. may be provided in any form. Also, the program may be downloaded from an external device via a network.

The flow of processing described in the above embodiment is an example, and unnecessary steps may be deleted, new steps added, or the order of processing may be changed without departing from the scope.
