Road vehicle driver behaviour analysis method
First Claim
1. A road vehicle (1) driver behaviour analysis method, the analysis method comprising the steps of:
- determining and memorizing an instantaneous position of the vehicle (1) expressed in geographic coordinates;
determining and memorizing at least one dynamic characteristic characterizing motion of the vehicle (1);
classifying a current road section just travelled by the vehicle (1) and defined by a start point and an end point having respective geographic coordinates;
determining a space-dependent pattern of the dynamic characteristic along and from the start point to the end point of the current road section;
determining a deviation between the space-dependent pattern of the dynamic characteristic along the current road section, and a space-dependent mean pattern or statistical distribution of the dynamic characteristic along the same or a similar road section and determined in previous runs of the vehicle (1);
updating, only using the space-dependent pattern of the dynamic characteristic along the current road section, the space-dependent mean pattern or statistical distribution of the dynamic characteristic along the same or similar road section, if an absolute value of the deviation is below a first threshold; and
identifying anomalous driver behaviour, and not using the space-dependent pattern of the dynamic characteristic along the current road section to update the space-dependent mean pattern or statistical distribution of the dynamic characteristic along the same or similar road section, if the absolute value of the deviation is above a second threshold;
wherein an analysis unit is utilized to perform at least the classifying, determining the space-dependent pattern, determining a deviation, updating and identifying steps.

Abstract
A road vehicle (1) driver behavior analysis method, the analysis method including the steps of determining and memorizing the instantaneous position of the vehicle (1) expressed in geographic coordinates; determining and memorizing at least one dynamic characteristic characterizing motion of the vehicle (1); classifying a current road section just travelled by the vehicle (1); determining the space-dependent pattern of the dynamic characteristic along the current road section; determining a deviation between the space-dependent pattern of the dynamic characteristic along the current road section, and a space-dependent mean pattern or statistical distribution of the dynamic characteristic along the same or a similar road section and determined in previous runs of the vehicle (1); and identifying anomalous driver behavior if the absolute value of the deviation is above a given threshold.
