The invention provides a hand release detection method and device for a vehicle steering wheel, and relates to the technical field of vehicle safety, and the method comprises the steps that in response to starting of a vehicle, an excitation source is controlled to generate a first excitation signal; the first electrode is used for processing the first excitation signal and then transmitting the first excitation signal to a vehicle steering wheel; receiving a second excitation signal conducted by a second electrode on the steering wheel, wherein the second excitation signal is generated after the first electrode and the second electrode act on the processed first excitation signal; and judging whether the steering wheel slips out of the hand according to the second excitation signal. Therefore, whether the hand is separated from the steering wheel or not is detected by sending the excitation signal, the steering wheel hand release detection accuracy can be improved, and the detection cost is reduced.
本公开提出了一种用于车辆方向盘的脱手检测方法及其装置,涉及车辆安全技术领域,该方法包括:响应于车辆的启动,控制激励源产生第一激励信号;对第一激励信号进行处理后传导至车辆方向盘上的第一电极;接收方向盘上第二电极传导的第二激励信号,其中第二激励信号由第一电极与第二电极对处理后的第一激励信号作用后生成;根据第二激励信号,判断方向盘是否脱手。由此,通过发送激励信号对人手是否脱离方向盘进行检测,可以提高方向盘脱手检测的准确度,并降低检测成本。
