The invention provides a fatigue driving behavior detection method and a fatigue degree judgment model training method. The detection method comprises the following steps: acquiring inertial measurement data acquired by an inertial measurement unit arranged on a steering wheel; steering wheel rotation angle separation and gravity factor elimination are carried out to obtain steering wheel rotation angle data and linear acceleration data; performing feature extraction on the steering wheel angle data and the linear acceleration data to obtain fatigue features and vehicle operation features; the fatigue features and the vehicle operation features are input into a fatigue degree judgment model for fatigue degree recognition, and a fatigue driving behavior detection result is obtained; and performing fatigue reminding according to a fatigue driving behavior detection result. Only one inertial measurement unit installed on the steering wheel is adopted to collect inertial measurement data, the inertial measurement data are processed, fatigue detection is achieved in combination with the trained fatigue degree judgment model, fatigue reminding is conducted on a driver, and cost is low.

    本申请提供了一种疲劳驾驶行为检测方法以及疲劳程度判断模型的训练方法。其中检测方法包括:获取设置于方向盘上的惯性测量单元所采集的惯性测量数据;对进行方向盘转角分离和重力因素消除得到方向盘转角数据和线性加速度数据;对所述方向盘转角数据和线性加速度数据进行特征提取得到疲劳特征和车辆操作特征;将疲劳特征和车辆操作特征输入疲劳程度判断模型进行疲劳程度识别得到疲劳驾驶行为检测结果;根据疲劳驾驶行为检测结果做出疲劳提醒。仅采用一个安装于方向盘上的惯性测量单元采集惯性测量数据,对惯性测量数据进行数据处理,并结合训练好的疲劳程度判断模型实现疲劳检测,并对驾驶者进行疲劳提醒,成本低。
