| 摘 要： | 将驾驶方向盘运动信息及道路偏移值作为驾驶员疲劳表征信息，通过模拟器的模拟驾驶实验，采集10名驾驶员疲劳表征数据，建立神经网络模型对驾驶员疲劳状态进行检测.基于PVT（Psychomotor Vigilance Task）测试结果及驾驶录像，采集清醒状态与疲劳状态的实验数据，并进行分析；然后对数据进行离散化和归一化，作为神经网络模型的输入.采用BP算法对神经网络模型进行训练，直至满足误差要求.实验结果表明，该方法检测驾驶员疲劳状态的准确率较高，实用性较强.

| Abstract: | The steering wheel motion and lateral position were used to evaluate the driver's fatigue based on the driving experiments on driving simulator.The driver's fatigue detection system was developed by neural network.Data of ten driver's driving experiments are collected and divided into two levels of fatigue based on the PVT(psychomotor vigilance task) testing and record video.And then,the data are processed off-line to find the difference between alert and fatigue.As the input data of neural network,the stee... |
