The invention belongs to the technical field of safe driving, and particularly relates to a detection method for preventing a driver from disability based on steering wheel holding induction, and the method comprises the following steps: S1, obtaining a face image of a driver in real time, and judging whether the driver is in a fatigue state or not according to the face image; s2, detecting the time when the two hands of the driver break away from the steering wheel, and judging whether the driver is in an abnormal driving state or not according to the time when the two hands break away from the steering wheel. The face image of the driver is obtained in real time, whether the driver is in the fatigue state or not is judged according to the face image, when the time when the driver is in the fatigue state or in the abnormal driving state exceeds the set safety time threshold value, the vibration reminding device is triggered, it is guaranteed that the driver focuses on attention when driving the automobile, and the driving safety is improved. Whether the two hands of the driver hold the steering wheel or not is determined by detecting the human body infrared signals, the detection efficiency of the situation that the two hands of the driver do not hold the steering wheel can be improved, and the real-time requirement of safe driving is met.
本发明属于安全驾驶技术领域,尤其是一种基于方向盘握持感应的防驾驶员失能的检测方法,包括以下步骤:S1:实时获取驾驶员的面部图像,并根据面部图像判断驾驶员是否处于疲劳状态;S2:检测驾驶员的双手脱离方向盘的时间,根据双手脱离方向盘的时间判断驾驶员是否处于非正常驾驶状态。本发明通过实时获取驾驶员的面部图像,根据面部图像判断驾驶员是否处于疲劳状态,当驾驶员处于疲劳状态或驾驶员处于非正常驾驶状态的时间超过设定的安全时间阈值,触发震动提醒装置,保证了驾驶员在驾驶汽车时的注意力集中,通过检测人体红外信号确定驾驶员双手是否握持方向盘,能够提高对驾驶员双手未握持方向盘的检测效率,满足安全驾驶的实时性要求。
