| 摘 要： | 驾驶员行为状态的识别对机动车驾驶的安全性有很重要的意义。采用汽车方向盘角度α作为输入，汽车偏离路面车道中心线的垂直位移S作为输出来建立模型，并观察模型参数（自然频率和阻尼比）的变化规律，用于判断驾驶员是否处于疲劳状态。同时，用疲劳时位移序列S的方差会不断变大来验证上述方法的正确性。

| Abstract: | Identification of driver state is a desirable element of many proposed vehicle active safety systems. In this study, a black-box system identification approach, using steering wheel position α as the input and vehicle lateral position S as the output, is used to develop a model and to update its parameters during driving. It is possible that changes in physical system parameters （damping ratio and natural frequency） can be related to fatigue. Additionally, another identification method is to use the variance of the vehicle lateral position S to monitor driver＇s state and to confirm the validity of the above method. |
