Abstract: Systems and methods of shielding a hand sensor system in a steering wheel are disclosed herein. An exemplary hand sensor system includes a sensor mat and a heater mat that is disposed between the sensor mat and a frame of the steering wheel. A power source selectively provides a heating current to the heater mat to provide heat to the steering wheel and a shielding voltage signal to the heater mat to provide electrical shielding for the sensor mat when heating is not needed or when sensing takes priority over heating. Alternatively, the system may include a shield mat that is separate from the heater mat and is disposed between the sensor mat and the heater mat. In addition, to isolate the signal carried by individual sensor return wires, a metallic or insulating covering or conduit may be provided around the wires or portions thereof.

Abstract translation: 本文公开了在方向盘中屏蔽手传感器系统的系统和方法。 示例性的手感传感器系统包括传感器垫和设置在传感器垫和方向盘的框架之间的加热垫。 电源选择性地向加热器垫提供加热电流以向方向盘提供热量，并且向加热器垫提供屏蔽电压信号，以在不需要加热时或者当感测优先于加热时为传感器垫提供电屏蔽。 或者，系统可以包括与加热垫分离并且设置在传感器垫和加热器垫之间的屏蔽垫。 此外，为了隔离由各个传感器返回线承载的信号，可以在电线或其部分周围设置金属或绝缘覆盖物或导管。

Abstract: An occupant detection system includes a controller, a sensing electrode, and a shield electrode, the electrodes disposed in a vehicle seat. The controller is electrically coupled to the sensing electrode and shield electrode by a sensing circuit. The controller is configured to send an input signal to the sensing electrode, the shield electrode, or both and measures current, impedance, or capacitance values to determine the presence of an object on the seat, to classify the object, or both.
