Research on Fatigue Driving Based on Pulse Blood Oxygen Signal

通过疲劳驾驶模拟实验,采集驾驶员在驾驶过程中的脉搏血氧饱和度,对不同驾驶状态下脉搏血氧的变化规律以统计学方法进行研究,分析不同驾驶状态下、不同时间窗内脉搏血氧平均值和标准差的差异性,优化出最优时间窗下的血氧疲劳特征参数,获得了较为准确的疲劳驾驶特征参数,对研究疲劳驾驶具有一定的参考价值。

Through the simulation experiment of fatigue driving, collecting the pulse blood oxygen saturation of drivers during driving. with statistical methods, conducting the research on the changes of pulse oxygen in different driving conditions, analyzing the difference of mean value and standard deviation of pulse blood oxygen in different driving conditions and different time window, optimizing the fatigue characteristic parameter of blood oxygen under optimal time window, thus, more accurate fatigue driving characteristic, parameters are obtained, which has certain reference value to study fatigue driving.
