A METHOD FOR IDENTIFYING VEHICLE PERFORMANCE

The present invention relates to a method for identifying vehicle performance, the method comprising: maintaining a database with clustered reference data based on first vehicle data, in which each cluster in the clustered reference data is associated with a cluster significant parameter being a cluster threshold indicative of the association of the corresponding cluster; collecting second vehicle data; identifying the second vehicle data with regards to the clusters of the clustered reference data by means of an associated significant parameter and a cluster threshold, and in response of not being able to classify the second vehicle data into a cluster of the clustered reference data, define the second vehicle data as an outlier; identifying vehicle performance based on the cluster identification and determined outlier of the second vehicle data.
