Patent ID: 8260491

Claim:
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.
