ABNORMALITY ANALYSIS SYSTEM FOR VEHICLE AND ABNORMALITY ANALYSIS METHOD FOR VEHICLE

摘要

When an abnormality of a vehicle is detected based on a vehicle state value that indicates the vehicle state, an abnormality analysis system for the vehicle estimates a cause of the abnormality. The abnormality analysis system includes: a factor identifying information extraction unit that extracts factor identifying information which is used to identify a factor of the abnormality based on the vehicle state value; a database that contains data groups which correspond to respective categories of the factor identifying information and which store causes of abnormalities and vehicle state values at the time of occurrence of the abnormalities; and an abnormality cause estimation unit that executes a process for estimating the cause of the abnormality of the vehicle with the use of the data group that corresponds to the category of the factor identifying information extracted by the factor identifying information extraction unit.
