Patent ID: 8359134

Claim:
An in-vehicle component assessment system for assessing severity of usage conditions degree for a specified component equipped in a vehicle, said system comprising: an in-vehicle terminal, which is equipped in the vehicle and comprises: an operation data acquisition unit, which sequentially, over time, acquires operation data regarding the specified component, and an operation data output unit, which outputs the operation data acquired by the operation data acquisition unit; and a center unit comprising: an operation data input unit, which receives the operation data output from the operation data output unit, an operation data storage unit, which stores the operation data received by the operation data input unit, an assessment regulation storage unit, which is prestored with assessment regulations which specify a relationship between the operation data and assessment information corresponding to degrees of the severity of the usage conditions for the specified component, an assessment information storage unit, which is prestored with relative comparison assessment information which is a reference for determining a value of the degree of the severity of the usage conditions for the specified component, a center control unit, which generates assessment information of the specified component based on the operation data stored in the operation data storage unit and the assessment regulations stored in the assessment regulation storage unit, and generates report information for producing a report to compare the generated assessment information to the relative comparison assessment information, and a report information output unit, which outputs the report information generated by the center control unit; and a user terminal which comprises a display unit and is connected to the center unit via a predetermined network, wherein: the report information output unit of the center unit is a transmitter-receiver which transmits and receives information via the network, the user terminal transmits report request information requesting provision of the report information to the center unit via the network, the transmitter-receiver of the center unit transmits the report information generated by the center control unit to the user terminal upon reception of the report request information, the display unit displays the report information received by the user terminal, the assessment information of the specified component displayed in the report includes the value of the degree of the severity of usage conditions for the specified component, the generated assessment information corresponds to a specific vehicle, the relative comparison assessment information includes assessment information corresponding to other vehicles, and the report is displayed in a user viewable form to compare the assessment information corresponding to the specific vehicle in a predetermined period to the relative comparison assessment information corresponding to the other vehicles in the predetermined period.
