1. A method for automatically assessing performance of a driver of a current vehicle for a particular current trip, wherein updated current-trip driving data sets are repeatedly read from the vehicle, the current-trip driving data sets each comprises data from at least a predetermined set of basic driving data parameters, wherein new such current-trip driving data sets are read from the vehicle at consecutive observation time points separated by at the most a predetermined observation time period, wherein the method comprises the steps of:

  • a) collecting previous-trip driving data sets, observed at a plurality of different observation time points, for a plurality of different previous trips made by a plurality of different drivers and a plurality of different vehicles, the previous-trip driving data sets each comprises parameter values for at least a certain predetermined set of qualified driving data parameters in turn comprising the basic driving data parameters and in particular instantaneous vehicle energy consumption;

    b) classifying said previous-trip driving data sets into a set of collections, wherein each of said collections only comprises previous-trip driving data sets for a particular class of vehicles, wherein all previous-trip driving data sets of one and the same vehicle are classified into one and the same collection, based upon a basic class conformity measure between driving data sets for the vehicle in question and a set of class-defining parameters;

    c) classifying the current vehicle into a particular current class based upon said basic class conformity measure; and

    d) calculating an energy consumption-based trip performance parameter value for the current trip based upon respective energy consumption-based performance parameter values for previous-trip driving data sets in said current collection;

    whereinthe basic driving data parameters comprises instantaneous vehicle velocity and instantaneous engine rotation speed and/or the basic driving data parameters comprises instantaneous motor load and instantaneous energy consumption, and wherein the class-defining parameters comprise, for each class of vehicles, a characteristic engine rotation speed for a particular vehicle velocity and/or a characteristic energy consumption for a particular motor load.
