Method and system for assessing the trip performance of a driver
First Claim
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 parameter set and in particular instantaneous vehicle energy consumption;
b) mapping each of said current-trip driving data sets to a respective basic historic group of said previous-trip driving data sets using a basic group conformity measure between a current-trip driving data set and a basic historic group of said type; and
c) calculating an energy consumption-based trip performance parameter value for the current trip based upon a respective energy consumption-based group performance parameter value for each mapped basic historic group;
whereinsaid basic parameter set comprises instantaneous velocity, instantaneous engine rotation speed, instantaneous velocity change and instantaneous engine rotation speed change, and/or the basic parameter set comprises instantaneous motor load, instantaneous energy consumption, instantaneous motor load change and instantaneous energy consumption change, and wherein these parameter values, for the data sets in question, are used for calculating said basic group conformity measure.
