The invention discloses a fatigue driving early warning method and system based on multiple fusion fatigue characteristics, the fatigue driving early warning method is applied to an intelligent automobile, and the method comprises the steps: carrying out the model matching of multiple different fatigue characteristics, and obtaining a matching degree result; the fatigue features comprise eye features, body motion features and physiological parameter features; performing weighted fusion processing based on the matching degree result to obtain a fatigue degree quantized value; determining that the quantized value of the fatigue degree is higher than a preset value, and generating a user perception early warning instruction; and in response to the user perception early warning instruction, carrying out user early warning prompt on the vehicle driver and/or the passenger. Fatigue detection is carried out through different fatigue characteristics, the accuracy of fatigue detection is improved, a user is prompted to pay attention to safe driving through different touch feelings, and the safety of vehicle driving is improved.

    本发明公开基于多种融合疲劳特征的疲劳驾驶预警方法及系统,该疲劳驾驶预警方法,应用于智能汽车,包括:对多种不同疲劳特征分别进行模型匹配得到匹配度结果;所述疲劳特征包括眼部特征、身体运动特征及生理参数特征;基于所述匹配度结果进行加权融合处理得到疲劳程度量化值;确定所述疲劳程度量化值高于预设值,生成用户感知预警指令;响应于所述用户感知预警指令,对所述车辆驾驶员和/或乘客进行用户预警提示。本发明通过不同疲劳特征进行疲劳检测,提高疲劳检测的准确度,并以不同触感提示用户注意安全驾驶,提高车辆驾驶的安全性。
