摘要
采用基于驾驶员驾驶操作行为及车辆行驶状态的方法研究驾驶疲劳问题,阐述了系统识别的原理,取车辆转向、座椅压力分布、座椅压力分布不对称系数Cu作为驾驶疲劳的识别特征指标。利用模块化思想,设计了系统的硬件/软件部分,对采集的数据利用设计的驾驶疲劳识别算法进行分析,确定方向盘动作频率和座椅压力变化情况与疲劳状态的相关性。
This paper researches the driving fatigue problem based on drivers' operation behavior and the status of the vehicle driving,elaborates the principles of system recognition by using the vehicle steering,the pressure distribution of seats,asymmetry coefficient Cu of pressure distribution of seats as the characteristic indexes of driving fatigue recognition. By using the advantages of modularization thought,it designs the hardware part and software part,and analyzes the collected date by driving fatigue recognition algorithm to confirm the correlation between steering wheel frequency and change of seat pressure and fatigue status.
