The invention relates to the technical field of vehicle seat systems, in particular to a seat capacitance sensor based on conductive fabric and a measuring method. The seat capacitive sensor based on conductive fabric is characterized in that an upper layer and a lower layer of a non-woven fabric felt layer are respectively connected with a first conductive fabric layer and a second conductive fabric layer by using a binder; the first conductive fabric layer and the second conductive fabric layer are formed by plating copper or nickel on fiber cloth through an electroplating process, and the thickness of the first conductive woven fabric layer and the second conductive woven fabric layer is less than 2mm; the thickness of the capacitive sensor is less than 4mm; and the area of the first conductive weaving layer is smaller than that of the non-woven fabric felt layer and that of the second conductive weaving layer. Compared with the prior art, the capacitive sensor which is light, soft and low in cost is designed by utilizing the characteristics of the conductive fabric, and the capacitive sensor is applied to the automobile seat, so that the state of the automobile seat can be adjusted in real time according to the posture of a passenger, and the overall comfort of the automobile seat is improved.

    本发明涉及车辆座椅系统技术领域,具体地说是一种基于导电织物的座椅电容传感器及测量方法。一种基于导电织物的座椅电容传感器,其特征在于:位于无纺布毛毡层的上层及下层分别采用粘结剂连接第一导电织布层及第二导电织布层;第一导电织布层及第二导电织布层是将铜或者镍通过电镀的工艺镀在纤维布上,并且第一导电织布层及第二导电织布层的厚度小于2mm;电容传感器的厚度小于4mm;第一导电织布层的面积小于无纺布毛毡层及第二导电织布层的面积。同现有技术相比,利用导电织布的特性,设计一款轻便、柔软、成本低的电容传感器,并将该电容传感器应用在汽车座椅上,可以实时根据乘员的姿势调节汽车座椅的状态,提高汽车座椅的整体舒适性。
