摘要： In addition to the loading mode of a capacitive sensing device (12) of a seat occupancy detection and classification system (10), a second measurement mode is introduced, which allows a discrimination of objects (CRS or human) with and without grounding condition. Depending on the value of the second measurement, the data is allocated to different groups which are subject to different thresholds in the loading mode. This means that if the second measurement indicates a grounding condition of the object, a higher threshold in the loading mode will be applied. In this way a Child Restraint System grounded by Isofix anchorages will be classified by means of the higher threshold, resulting in a robustness increase. Typical human sitting positions do not show a grounding condition and will be classified by the lower threshold.
摘要翻译：除了座位占用检测和分类系统（10）的电容式感测设备（12）的加载模式之外，还引入了第二测量模式，其允许区分物体（CRS或人）有和没有接地条件。根据第二次测量的值，将数据分配给在加载模式下受不同阈值影响的不同组。这意味着如果第二次测量指示物体的接地状况，则将应用加载模式中较高的阈值。通过这种方式，通过更高的阈值将被Isofix锚固点固定的儿童约束系统分类，导致稳健性增加。典型的人体坐姿不会显示接地情况，并会按照较低的阈值进行分类。

摘要： The upholstered seat element of a vehicle seat includes a cushion, a trim cover fixed to the cushion along an attachment seam and an integrally formed planar textile electrode extending substantially parallel to the trim cover, the textile electrode being formed of interwoven conductive fibres. The electrode comprises a first electrode region arranged on one side of the attachment seam, a second electrode region arranged on the other side of the attachment seam and a transition region connecting the first electrode region to the second electrode region where the electrode overlaps with the attachment seam. The electrode comprises, in the transition region, only such conductive fibres that extend from the transition region into at most one of the first and second electrode regions, so that, in response to stress acting along a direction across the attachment seam, those conductive fibres extending from the transition region only into the first electrode region may be shifted with respect to those conductive fibres extending from the transition region only into the second electrode region, thereby enabling an elongation of the transition region in the direction of the stress.

摘要： A capacitive occupant detection system has an oscillator and an electrode operatively coupled to the oscillator, to which the oscillator applies an oscillating voltage signal. In response to the oscillating voltage being applied, an electric current is caused to flow in the electrode, the current being responsive to an electric-field-influencing property of an object or occupant proximate to the electrode. The current caused to flow in the electrode has a first current component in phase with the oscillating voltage signal and a second current component 90°-phase-offset with respect to the oscillating voltage signal. A sensing circuit is operatively coupled to the electrode and to the oscillator so as to generate a first signal indicative of the first current component and a second signal indicative of the second current component. The first signal indicative of the first current component and the second signal indicative of the second current component are provided to a processor, which is operatively coupled to the sensing circuit and which determines an occupancy state based upon the first and second signals indicative of the first and second current components, respectively, and outputs an output signal indicative of the occupancy state.

摘要： An automotive vehicle has arranged therein a vehicle seat and is equipped with an occupant detection system for detecting whether an occupant is present on the vehicle seat. The occupant detection system includes a first antenna electrode arranged in the seat and a sensing circuit associated with the seat. The sensing circuit comprises an oscillation circuit connected to the first antenna electrode for applying to the first antenna electrode a first oscillating signal and a current detection circuit also connected to the first antenna electrode for determining a first current flowing in the first antenna electrode in response to the first oscillating signal being applied. 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 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. In particular, the occupant detection system includes a second antenna electrode arranged together with the appliance control device. An oscillator is operatively connected to the second antenna electrode for applying a second oscillating signal to the second antenna electrode and the current detection circuit is configured for determining a second current flowing in the first antenna electrode in response to the second oscillating signal being applied to the second antenna electrode. The second current thus indicates whether an occupant of the vehicle seat has a part of their body proximate to the appliance control device.

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.
