Other characteristics of the movement detection of a conductor of a vehicle, in view of a diagnosis of the lowering of vigilance of said conductor

摘要

The present invention relates to a method for the detection of the characteristic movements of a vehicle driver, in view of a diagnosis of the lowering of vigilance of the said driver. According to the invention, and in a preliminary phase, it divides the surface of the seat (a) and of the back (d) of the seat (s) into a plurality of elementary surfaces in each of which is implanted a pressure sensor (an, n - dn, n) is able to detect the supports and the relaxation exerted by the driver on the said pressure sensor, and it selects a plurality of specific movements, which is characterized by the determination of at least one geographic zone subjected to a "support " or" releasing " resulting from the said movement. In addition, the data processing consists in analyzing the measurement signals delivered by the pressure sensors, and to compare, at each sampling instant t, any geographic zones and of releasing detected with each of the geographical zones are stored, so as to provide an information for the detection of a specific movement during a correlation between the geographical zones.
