A system for the detection of a seat occupancy in a vehicle, comprises first and second capacitive electrodes (1,2), said first and second capacitive electrodes being arranged in a compartment of said vehicle, and a driver and evaluation circuit (20), operatively connected to said first and second capacitive electrodes. According to the invention, the first capacitive electrode (1) is arranged in a seat (22) of the vehicle while the second capacitive electrode (2) is arranged in a foot-area of the vehicle, and the driver and evaluation circuit comprises means for driving said first capacitive electrode and determining a capacitive coupling with a conductive object placed on said seat and means for driving said second electrode and determining a capacitive coupling between said second electrode and said first electrode. |
