Abstract

The invention is related to a driver behavior diagnostic method. The method involves sampling event signal values associated with a vehicle and analyzing the event signal values. The sampling of the event signal values includes buffering the values over a limited buffer time. The analyzing of the event signal values includes reconstructing events based on the buffered event signal values. Further, the invention is related to a driver behavior diagnostic system including a sampling device for sampling event signal values associated with a vehicle and an analyzing device for analyzing the event signal values. The sampling device includes a buffer for buffering event signal values for a limited buffer time, and the analyzing device is adapted for reconstructing events based on the buffered event signal values.
