Method and system for assessing the trip performance of a driver
First Claim
1. A computer-implemented 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 and electronically read from the vehicle, the current-trip driving data sets each comprise data from at least a predetermined set of basic driving data parameters, wherein the current-trip driving data sets are electronically read from the vehicle at consecutive observation time points separated by no more than a predetermined observation time period, wherein the method comprises determining a value of a second trip performance parameter by the steps:
- a) collecting previous-trip driving data sets, each electronically observed at a respective one of 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 comprise parameter values for at least a certain predetermined set of qualified driving data parameters that comprise the basic parameter set, and the parameter values are each read either as a respective instantaneous value or a respective average value read across a certain respective time period of at the most 5 seconds of length;
b) for each of said current-trip driving data sets, automatically selecting at least one corresponding previous-trip data set according to at least one of;
i) a predetermined basic driving data set similarity measure that indicates similarity between driving data sets, or ii) a predetermined basic group conformity measure that indicates conformity of the current-trip data set to a basic historic group of previous-trip driving data sets; and
c) determining the value of said second trip performance parameter from the respective values of a first trip performance parameter for each of said selected previous-trip driving data sets, wherein each first trip performance parameter is calculated for the respective previous-trip data set as a relative trip performance of the previous-trip data set in relation to the trip during which the previous-trip data set was observed, and wherein the second trip performance parameter value is calculated by and communicated, via a wireless link, from a central server to at least one of the vehicle or a portable electronic device, and presented to the driver.

Abstract
Method for automatically assessing performance of a driver (110) of a vehicle (100) for a particular trip, wherein current driving data sets, comprising basic driving data are repeatedly read from the vehicle, which method comprises the steps a) collecting previous-trip driving data sets, comprising instantaneous vehicle energy consumption, for different previous trips, different drivers and different vehicles; b) for each of said current-trip driving data sets, selecting a corresponding previous-trip data set; c) calculating the value of said second trip performance parameter based upon the respective values of a first trip performance parameter for each of said selected previous-trip driving data sets, which first trip performance parameter is calculated for the previous-trip data set in question as a relative trip performance of the previous-trip data set in question in relation to the trip during which the previous-trip data set was observed. The invention also relates to a system.
