Provided is a contact determination method in which a sheet-like electrode section, which is configured by laminating a first electrode and a second electrode with an insulator interposed therebetween, is provided so as to cover the outer peripheral section of a steering wheel, and contact of a driver with the steering wheel is determined on the basis of an electric signal detected from the electrode section. The contact determination method includes: a detection step of detecting capacitance and impedance generated in the electrode portion; and a determination step for determining, on the basis of the capacitance and impedance detected in the detection step, whether or not the driver's hand has contacted the steering wheel and whether or not the electrode part is abnormal. In the determination step, when the capacitance exceeds a first threshold value and the impedance is lower than a second threshold value, it is determined that the electrode portion is abnormal.

    一种接触判定方法,将使第一电极与第二电极隔着绝缘体层叠而构成的片状的电极部以覆盖方向盘的外周部的方式设置,基于从电极部检测到的电信号,来判定驾驶员对方向盘的接触。该接触判定方法包括以下步骤:检测步骤,检测在电极部中产生的静电电容及阻抗;以及判定步骤,基于在检测步骤中检测到的静电电容及阻抗,来判定驾驶员的手是否接触了方向盘、以及电极部是否异常。在判定步骤中,在静电电容超过第一阈值、且阻抗低于第二阈值的情况下,判定为电极部异常。
