Abstract: A sensor system for a motor vehicle is provided. The sensor system comprises a flat shielding element which is electrically conductive and to which an electric potential can be applied, and at least one capacitive sensor element which includes an electrically conducting structure which is arranged on one side of the shielding element. As electrically conducting structure the sensor element includes at least one sensor conductor which forms a sewing thread and is sewn onto the one side of the shielding element.

Abstract: A method and a device for testing an electronic appliance for determining at least one variable of a system. The electronic appliance is designed in the form of a sensor. The method includes defining an expected minimum and/or maximum value of the variable and producing an electric signal by means of the electronic appliance depending on the variable. The method also includes detecting at least one value of a parameter of the produced electric signal and defining an expected minimum and/or maximum value of the parameter depending on the defined minimum and/or maximum value of the variable of the system. A determination is made, based on whether the detected value of the parameter is greater than the minimum value defined for the parameter and/or smaller than the maximum value, whether there is a malfunction of the electronic appliance provoked by an external electromagnetic interference field.

Abstract: A capacitive sensor assembly for a motor vehicle is provided. The capacitive sensor assembly includes a capacitive sensor element which has at least one first electrical conductor element, and a reference conductor element defining an electrical reference potential and being interspaced from the first electrical conductor element. The first electrical conductor element is designed as an outer conductor surrounding the reference conductor element which represents the inner conductor.

Abstract: A vibrator assembly for a vehicle for generating an oscillation of a vehicle part detectable by a person is provided. The vibrator assembly comprising a vehicle part having a supporting structure and a case connected with said supporting structure, and a vibrator surrounded by the case which is formed to stimulate the case to oscillate whereby the oscillations are perceivable by a person. The vibrator for stimulating the oscillations of the case is coupled via at least one spring element differing from the case with the supporting structure of the vehicle part so that the oscillations of the case are stimulated via the supporting structure.

Abstract: A sensor system for a steering wheel of a motor vehicle is provided, characterized in that, in one form, in and/or on a steering wheel rim at least one sensor device for recording the effects of an acceleration is arranged. Rapid and effective reactions can thus be made to impact events, for example.

Abstract: A measuring system is provided. The measuring system comprising at least a first measuring means for detecting at least one frequency-independent electrical quantity and an evaluation unit for detecting the temporal behaviour of the frequency-independent electrical quantity. The evaluation unit automatically generates from the detection of the temporal course of the frequency-independent electrical quantity a signal that is at least partially equivalent to a frequency-dependent signal. Furthermore a measuring method is provided, in which at least a first measuring means detects at least a frequency-independent electrical quantity and an evaluation unit detects the temporal behaviour of the frequency-independent quantity. The evaluation unit automatically generates a signal from the detection of the temporal course of the frequency-independent electrical quantity, which signal is at least partially equivalent to a frequency-dependent quantity.
