摘要： A capacitive seat occupancy detection and classification system (10) with a capacitive sensor having at least two distinct antenna electrodes (18, 20) and a method of operating is proposed to reduce an impact of the sensor-to-object impedance Z so on an object-to-ground impedance Z OG measurement that the system performs. By measuring the impedance between the different antenna electrodes by the system, additional information is obtainable that can be used to compensate the impact of the sensor-to-object impedance Z so on the object-to-ground impedance. As one effect of combining both impedance measurement results, the proposed system is able to determine the object-to-ground impedance Z OG completely independent from wear of ISOFIX anchorages or human objects touching the electric ground of the vehicle, thus ensuring a stable classification of the object over the entire vehicle lifetime. The method further enables high-resolution seat occupancy classification.

摘要： The present invention proposes to compensate the effect of the seat heater by either direct measurement of the current coupled into the seat heater or by indirect compensation by introducing an additional electrode into the system. This additional electrode, subsequently referred to as 'compensation electrode', may be integrated into the capacitive measurement system in such a way, that the capacitance between the sense electrode and this compensation electrode is subject to the same relative variations as the capacitance between the sense electrode and the seat heater.
