VEHICLE DATA ANALYSIS APPARATUS, VEHICLE DATA ANALYSIS METHOD, AND DEFECT DIAGNOSIS APPARATUS

摘要

A vehicle data analysis apparatus analyzes vehicle data that indicates chronological transition of a vehicle state. The vehicle data analysis apparatus is provided with a computing unit and a recognition unit. The computing unit is configured to make obvious data fluctuation accompanying the development, in the vehicle data, of mechanical or control-related defect in a vehicle control system. The recognition unit is configured to recognize the vehicle data to be considered during vehicle defect diagnosis on the basis of a result of computation by the computing unit.
