Vehicle-onboard apparatus system, portable terminal, and vehicle-onboard machine

摘要

A vehicle-onboard apparatus system, comprises a portable terminal and a vehicle-onboard machine (10) that are configured to be coupled to each other for communication. The portable terminal (20) and the vehicle-onboard machine (10) each store operation logs including operation contents thereof. When an operation of the vehicle-onboard machine (10) and an operation of the portable terminal (20) relate to each other, an operation log resulting from the operation of the vehicle-onboard machine (10) and an operation log resulting from the operation of the portable terminal (20) are associated with each other by first identification information. The vehicle-onboard machine (10) makes a user to recognize the first identification information corresponding to an operation causing detected predetermined state. When the portable terminal (20) receives an input of the first identification information presented by the vehicle-onboard machine (10), the portable terminal (20) acquires the operation log associated with the input first identification information. The portable terminal (20) analyzes the acquired operation log.
