摘要： A capacitive occupant detection system (10) comprises a sine signal generator (12) to apply a sine voltage signal to an antenna electrode (14) and a current measurement circuit (18, 20, 28, 30, 40) to measure current signals, based upon which a control and evaluation unit determines and outputs an occupancy state. The signal generator (12) is coupled to the antenna electrode via an amplitude adjustment stage (13), configured to adjust the amplitude of said sine voltage signal applied to said antenna electrode to an amplitude selected among at least two discrete amplitudes. The control and evaluation circuit selects one of the discrete amplitudes at a time and causes the amplitude adjustment stage to adjust the amplitude of said the voltage signal applied to the antenna electrode accordingly. The control and evaluation circuit carries out an interference detection mode and an occupant detection mode. In interference detection mode, the current signals are measured while a low one of the at least two discrete amplitudes is selected and it is determined whether the antenna electrode is exposed to interference. In occupant detection mode, the current signals are measured while a high one of the at least two discrete amplitudes is selected and occupancy state is determined based upon the current signals thus measured.

摘要： The method concerns operating a capacitive occupant classification system that comprises a sensing electrode and a shielding electrode arranged in a vehicle seat. The method comprises a measurement routine for classifying an occupancy state of the vehicle seat and a system check routine. In particular, the system check routine includes applying a first DC voltage difference between the sensing electrode and the shielding electrode and determining a leakage current caused by this first voltage difference between the sensing and shielding electrodes. Applying of the first voltage difference is terminated as soon as the testing indicates that the determined leakage current is not comprised in the predefined range of acceptable values, e.g. if the leakage current exceeds a certain reference value that indicates the highest tolerable leakage current.

The first current indicates whether an occupant is present on the vehicle seat. The vehicle is further equipped with an appliance including an appliance control device (600) arranged in the vehicle compartment at a location where it can be operated by an occupant of the seat. The occupant detection system is configured for detecting whether the occupant attempts to interact with the appliance control device.

摘要： A method for detecting an occupant of a vehicle seat using a capacitive occupant detector equipped with a transmission antenna electrode and a reception antenna electrode having between them a space that can be occupied by an occupant of the vehicle seat comprises the steps: applying oscillating signals to the transmission antenna electrode and thereby inducing corresponding received oscillating signals in the reception antenna electrode, detecting the received oscillating signals and deciding on an occupancy state of the vehicle seat based upon capacitive coupling strength between the transmission antenna electrode and the reception antenna electrode through the space. At least one of the transmission and reception antenna electrodes comprises a first end portion, a second end portion and an intermediate portion resistively interconnecting the first and second end portion. The method comprises further determining capacitive coupling strengths between the end portions of the antenna electrode that comprises a first end portion, a second end portion and an intermediate portion and the other antenna electrode, as well as the derivation of an occupancy state of the vehicle seat based upon the capacitive coupling strengths determined.
