Abstract: The present disclosure relates to a mat for detecting the occupancy of a motor vehicle seat, comprising a flexible support, an interdigitated capacitive sensor borne by the flexible support, a first conductive track borne by the flexible support, the first conductive track having a first end connected to the interdigitated capacitive sensor and a second end intended to be connected to a computing unit, a second conductive track borne by the support, the second conductive track having a first free end and a second end intended to be connected to the computing unit. The present disclosure also relates to a system for determining a capacitance, a method for determining a capacitance or a state of occupancy of a seat and a method for detecting a rotation of a part of the trunk of an occupant seated on a seat.

Abstract: The present disclosure relates to a method for determining the occupancy status of a seat of a motor vehicle, the method being implemented by a determination system comprising a seat, six interdigitated capacitive sensors, and a controller comprising a reference capacitance value and a threshold value for each interdigitated capacitive sensor, the method comprising a step of measuring three capacitance values for each interdigitated capacitive sensor, the following steps being implemented by the controller for the measured capacitance values: calculating a resulting capacitance value based on the measured capacitance values, calculating the difference between the resulting capacitance value and the reference capacitance value, comparing the calculated difference to the threshold value, determining the occupancy status of the seat, based on the result of the comparison.
