摘要： An occupant detection system comprises an electrode arrangement for placement into a seat of an automotive vehicle and an evaluation circuit operatively connected to the electrode arrangement. The latter includes a first electrode for emitting an electric field into a detection region above the vehicle seat, a second electrode and an electric insulator layer sandwiched between the first and second electrodes. When the electrode arrangement is in place in the seat, the first electrode forms with vehicle ground a first capacitor having a first capacitance, which is influenceable by an occupying item in the detection region through interaction of the occupying item with the electric field, the first electrode forms with the second electrode a second capacitor having a second capacitance and the second electrode forms with at least one of vehicle ground and a third electrode a third capacitor having a third capacitance. As a first indicator of the seat occupancy state, a measure of the first capacitance is determined while the first electrode is caused to emit an electric field into said detection region and the second electrode is operated as a driven shield for the first electrode. The fluctuations of at least one of the first, second and third capacitances are measured and the frequency spectrum of the measured fluctuations is analysed, which yields a second indicator of the occupancy state. The derivation of the occupancy state of the seat is then based on both the first indicator and the second indicator.

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.

摘要： A capacitive sensing circuit is disclosed, wherein the transimpedance amplifier in front of the mixer in prior art is removed respectively replaced by an amplifier with low gain and consequently high dynamic range. The mixer DC offset voltage or current together with the large amplification factor required after the mixer now would result in an inacceptable DC offset at the output of the signal chain. In order to eliminate the effect of the mixer offset, the amplifying stages after the mixer are AC coupled to the mixer output and one of the signals entering the mixer is phase modulated or amplitude modulated with a known low frequency signal. An additional mixer after the AC coupled amplifying stages is driven with the same low frequency modulating signal, resulting in the wanted DC output signal responsive to the capacitance to be measured.

摘要： A combined seat heater and capacitive occupancy sensor comprises a heater network including a heating element (11) and a capacitive sensing circuit connected to the heating element to sense a capacitive load. A first and a second interface are provided for connecting the heating element to a first and a second terminal of a power source, respectively. Each interface comprises electronically controlled switches (3, 5; 4, 6) arranged in series and defining an intermediate node (20; 21). An oscillator (8) is AC-coupled to the intermediate nodes to apply an oscillating voltage thereto. A current measuring means (9), AC-coupled between the oscillator and the heating element, keeps the AC-potential of the heating element at least substantially equal, in amplitude and phase, to the oscillating voltage on the intermediate nodes and to derive the capacitive load from a thus resulting current flowing into the heating element.
