The invention discloses a method and device for detecting disengagement from a steering wheel in a hand motion state of a driver. The detection method comprises the steps that S1, first equipment andsecond equipment are used for collecting driver hand motion data and vehicle driving state data at each moment respectively; S2, a first time window is searched according to the relative motion stateof the first equipment and the second equipment; S3, a characteristic value of first steering data under a world coordinate system is extracted in the first time window; and S4, a vehicle steering detection model is established, vehicle steering recognition is conducted on data collected in real time. The detection device is based on the method. The method is high in detection precision, is not liable to be affected by external interference, can complete detection without other sensing equipment, and is just suitable for large-scale popularization in the field.

    本发明公开了一种驾驶员手部运动状态下脱离方向盘检测方法及装置,检测方法包括:S1:利用第一设备和第二设备分别采集每一时刻的驾驶员手部运动数据和车辆行驶状态数据;S2:根据第一设备和第二设备的相对运动状态,寻找第一时间窗口;S3:在所述第一时间窗口中提取世界坐标系下的第一转向数据的特征值;S4:建立车辆转向检测模型,对实时采集到的数据进行车辆转向识别,检测装置基于上述方法。本发明检测精度高,不易受到外界的干扰,不安装其他传感设备,即可完成检测,只得在本领域大量推广。
