METHOD FOR DETECTING CHARACTERISTIC MOVEMENTS OF A VEHICLE DRIVER FOR VIGILANCE DECLINE DIAGNOSIS OF SAID DRIVER

摘要

The invention relates to a method for detecting characteristic movements of a vehicle driver with a view to a diagnosis of a decrease in vigilance of said driver. According to the invention, and in a prior phase, the surface of the seat (A) and the seat back (D) of the seat (S) is divided into a plurality of elementary surfaces in each of which a pressure sensor is installed (An , n - Dn, n) adapted to detect the supports and relaxations exerted by the driver on said pressure sensor, and a plurality of specific movements is selected which are each characterized by the determination of at least one geographical area subject to "support" or "relaxation" resulting from the said movement. In addition, the data processing consists in analyzing the measurement signals delivered by the pressure sensors, and in comparing, at each sampling instant t, the possible geographic areas of support and relaxation detected with each of the stored geographical areas. , so as to provide information for detecting a specific movement during a correlation between said geographical areas.
