Abstract

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 valuesat 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.

Description

technical field [0001] The present invention generally relates to an abnormality analysis system for a vehicle and an abnormality analysis method for a vehicle. More specifically, the present invention relates to an abnormality analysis system for a vehicle and an abnormality analysis method for a vehicle for estimating the cause of the abnormality if it is determined that an abnormality has occurred in the vehicle based on a vehicle state value representing the state of the vehicle. Background technique [0002] For example, Japanese Patent Application Publication No. JP-A-2006-251918 (JP-A-2006-251918) describes a failure analysis system that includes: a plurality of in-vehicle sensors that constantly obtain State information of the state; an in-vehicle information storage unit that stores state information related to equipment obtained by a plurality of in-vehicle sensors; a shared information database that is set outside the car and will be related to the failure phenome...
