1. A sensor system for a motor vehicle, which comprises:
a flat shielding element comprising a fabric of metal threads which is electrically conductive and to which a first electric potential is applied, and
at least one capacitive sensor element, which includes an electrically conducting structure which is arranged on a first side of the shielding element, wherein as electrically conducting structure, the at least one capacitive sensor element includes at least one sensor conductor which forms a sewing thread and is sewn onto the first side of the shielding element,
wherein a second potential is applied to the at least one sensor conductor, such that the fabric of metal threads of the shielding element masks any parasitic capacitance between the at least one sensor conductor and any electrically conductive material disposed adjacent a second side of the shielding element, wherein the second side of the shielding element is opposite and spaced apart from the first side of the shielding element,
a holding thread,
wherein the sensor conductor and the holding thread together form a seam, wherein the sensor conductor and/or the holding thread at least partially extend through the shielding element.
