The invention relates to a method for predicting the consciousness level of an L3-level driving takeover driver, and the method comprises the steps: dividing a takeover road into three sections according to environment factors and a current task condition; respectively acquiring the environmental factor probability, the environmental factor relative importance, the scene awareness prediction probability and the environmental complexity of each section; and based on the environmental factor probability, the environmental factor relative importance, the scene awareness prediction probability and the environmental complexity, obtaining the scene awareness level of a single section, and summing to obtain the scene awareness level of the driver of the takeover road. The situation awareness level prediction value of the driver in the takeover process is obtained based on the prediction method, so that the automatic driving system can better know the alertness degree of the driver in different road sections and send out a takeover request in time, and therefore traffic accidents caused by driving misoperation are reduced; and intelligent cooperation between the automatic driving system and the driver is further realized, and intelligent and humanized interaction is carried out.
本申请是关于一种L3级驾驶接管驾驶人情景意识水平的预测方法,包括根据环境因素和当前任务情况,将接管道路划分为三个区段;分别获取各个区段的环境因素概率、环境因素相对重要度、情景意识预测概率和环境复杂程度;基于环境因素概率、环境因素相对重要度、情景意识预测概率和环境复杂程度得到单个区段的情景意识水平,求和得到接管道路的驾驶人情景意识水平。基于预测方法得到接管过程驾驶人的情境意识水平预测值,使自动驾驶系统可以更好地了解驾驶人在不同路段的警觉程度,及时发出接管请求,从而减少驾驶操作失误造成的交通事故;进一步实现自动驾驶系统与驾驶人的智能合作,进行智能化、人性化的交互。
