Vehicle management system

摘要

A vehicle management system for monitoring vehicle maintenance conditions includes a self-diagnosing system mounted on a vehicle for monitoring a control system by an on-board diagnosis apparatus and for storing a diagnosis information with first data related to a target diagnosis when an abnormality is recognized and second data being close to a trouble determination level even though within a normal range. A data communication system transmits the diagnosis information to an outside receiver via a wireless communication. An external database system receives the diagnosis information to accumulate it. A network system analyzes the second data and distributes an analyzed result to at least one of a user of the vehicle and a department with an access right to the database system.
