Document Type and Number:
WIPO Patent Application WO/2020/110415
Kind Code:
A1
Abstract:
This vehicle log transmission device (10) is provided with: a vehicle log acquisition unit (110) for acquiring a vehicle log; a vehicle log division unit (120) that generates one or more divided logs by using an ID included in an acquired vehicle log to divide said vehicle log; an existing identifier storing unit (150) for storing an existing identifier list that is a list of identifiers corresponding to an existing divided log generated by using an ID included in an existing vehicle log shared between the vehicle log transmission device (10) and a vehicle log analysis server to divide said existing vehicle log; a vehicle log transmission necessity determination unit (140) that generates identifiers for each of the one or more divided logs, determines that a divided log corresponding to an identifier present in the existing identifier list among the generated identifiers is a first divided log, and determines that a divided log corresponding to an identifier not present in the existing identifier list is a second divided log; and a vehicle-side communication unit (170) that transmits the identifier corresponding to the first divided log to the vehicle log analysis server and transmits the second divided log to the vehicle log analysis server.
