본 발명의 바람직한 실시예에 따른 스티어링 휠의 핸즈 온/오프 감지 장치 및 방법은, 스티어링 휠(steering wheel)의 토크(torque) 값을 기반으로 주파수 분석을 수행하여 핸즈 온/오프(hands on/off)를 감지함으로써, 핸즈 온/오프 감지를 위한 추가적인 센서를 구비하지 않아도, 기존의 토크 센서(torque sensor)만을 이용하여 핸즈 온/오프 판단의 성능을 향상시킬 수 있다. The present disclosure detects hands on/off by performing a frequency analysis based on a torque value of a steering wheel, so that it is possible to improve performance of hands on/off determination by using only an existing torque sensor even without requiring an additional sensor for detecting hands on/off.
