본 발명의 스티어링휠 핸즈온오프 감지장치는 운전자의 움직임을 촬영하는 차량 내 촬상수단; 차량의 동역학적 움직임을 측정하는 동역학 센서; 촬상수단으로부터 획득된 이미지 처리를 하는 영상처리부; 영상처리부는 이미지로부터 운전자의 행동 유형을 도출하는 운전자 모니터링부; 및 운전자의 키포인트를 추출하는 키포인트 추출부를 포함하고, 운전자의 키포인트에 최적 토크 및 최적 접촉힘이 적용됨으로서 운전자의 위치를 추종하도록 최적제어되는 운전자 동역학 모델이 적용되고, 운전자 동역학 모델로부터 추정된 스티어링휠에 가해지는 힘의 크기에 의해 스티어링휠 핸즈온오프를 판단하는 차량안전제어부를 포함한다.

    A steering wheel hands-on/off detection device includes: an imaging part provided in a vehicle and configured to capture a motion of a driver; a dynamic sensor configured to measure a dynamics motion of the vehicle; an image processor configured to process an image obtained from the imaging part; and a vehicle safety controller. The image processor includes a driver monitoring part configured to derive a behavior type of the driver from the image and a keypoint extraction part configured to extract keypoints of the driver. An optimal torque and an optimal contact force are applied to the keypoints of the driver so that a driver dynamics model optimally controlled to follow a position of the driver is applied. The vehicle safety controller configured to determine steering wheel hands-on/off on the basis of a magnitude of a force applied to the steering wheel, which is estimated from the driver dynamics model.
