The invention provides a driver distraction state rapid discrimination and grading warning method and system, and relates to the technical field of automatic driving, and the method comprises the steps: obtaining the driving posture characteristics of a driver in real time, and carrying out the discrimination of various distraction behaviors of the driver according to the driving posture characteristics; related feature vectors are extracted from the vehicle dynamics data collected in real time, and driver distraction judgment is conducted according to the related feature vectors; and performing comprehensive analysis on the two judgment results, determining the vehicle operation risk level, performing warning of different levels, and starting automatic driving takeover under the high-level risk. According to the method, the distraction state of the driver can be quickly and accurately judged, corresponding warning and even automatic driving takeover are performed according to the distraction degree, and the safety of the automatic driving vehicle is improved.

    本发明提供了一种驾驶员分心状态快速判别与分级警示方法及系统,涉及自动驾驶技术领域,该方法包括:实时获取驾驶员的驾驶姿态特征,根据驾驶姿态特征进行驾驶员多类分心行为判别;从实时采集的车辆动力学数据中提取相关特征向量,根据相关特征向量进行驾驶员分心判别;对两次判别结果进行综合分析,确定车辆运行风险等级,并进行不同级别的警告,在高级风险下启动自动驾驶接管。本发明可以快速准确地判别驾驶员的分心状态,并根据分心程度进行相应的警示甚至自动驾驶接管,提高自动驾驶车辆的安全性。
