Capacitive proximity sensing

The invention discloses capacitive proximity sensing. A capacitive proximity sensor may include a proximity sensing capacitor to provide a voltage output based on a voltage input, the capacitor including a ground plane and an electrode loop capacitivelycoupled to the ground plane. The proximity sensor may include a processor to detect an object proximity based on a change in the voltage output. The proximity sensor provides automated detection of aperson, and thereby reduces the need for a vehicle occupant or child caregiver to activate a sensor by pressing a button. The use of a capacitance-based proximity sensor reduces issues associated with fabric, clothing, or other materials separating the proximity sensor from a person. 本申请公开了电容式邻近度感测。电容式邻近度传感器可包括邻近度感测电容器，用于基于电压输入提供电压输出，该电容器包括接地平面以及电容耦合至接地平面的电极回路。邻近度传感器可包括处理器，用于基于电压输出的改变来检测物体邻近度。此邻近度传感器提供对人的自动检测，从而减少车辆乘员或儿童看护者通过按下按钮来激活传感器的需要。基于电容的邻近度传感器的使用减少了与织物、衣物、或其他材料将邻近度传感器与人分隔开相关联的问题。
