其中，C为电容，d为两个传感器电阻丝之间的距离，A为传感器电阻丝的接触面积，ε为介电常数。

本发明采用车载微控制器MCU芯片，通过车载总线汽车总线相接，为了自适应不同厂家的总线通讯协议，硬件上集成了CAN总线、LIN线总线物理接口。
电源模块采用LDO电源系统，通过MCU对功耗进行管理。电源管理分为深度睡眠与轻度睡眠两种情况，极大的降低了终端的静态功耗，完全通过汽车低功耗的认证。
电容量检测模块采用专有的电容采取模块，采用总线方式读取电容导线的电容量，相对于空位置的电容量，通过数据去冗余和抖动等方法，获取乘员位置的变化，进一步驱动座椅舒适系统的控制阀门，以十分精准的方式控制阀门开启与关闭，从而调整系统内各个针对人体各部位气袋的支撑的位置，满足乘员的舒适性。同时为了系统可靠性，电路上增加短路与开路检测功能。
