1. A vehicle data analysis method for analyzing vehicle data reflecting a driver'"'"'s driving operation, comprising:
- collecting a plurality of pieces of vehicle data based on a plurality of types of driving operations;
grouping these collected pieces of the vehicle data into at least two groups based on an evaluation criterion that is an index for evaluating a level of the driving operation;
extracting characteristic values of vehicle data differing between the groups; and
obtaining a degree of influence exerted by the extracted characteristic value of vehicle data on the vehicle data evaluated based on the evaluation criterion.

Abstract
The invention provides a vehicle data analysis method that enables quantitative analysis of characteristics of vehicle data indicating transition in a driver'"'"'s driving operation, and a vehicle data analysis system using this analysis method. A plurality of vehicle data are collected based a plurality of types of driving operations. Based on an evaluation criterion as an index for evaluating levels of the driving operations, the collected vehicle data are grouped into at least two groups. Characteristic values of the vehicle data differing between these groups are extracted.
