防疲劳驾驶系统的设计

The Design of Fatigue Driving Preventing System

设计一套集疲劳驾驶计时功能、疲劳驾驶检测功能、疲劳驾驶警示灯显示功能、GPS疲劳语音提示功能及GPS定位功能于一体的防疲劳驾驶系统,绘制工作流程图。通过模拟驾驶器模拟实际驾驶,对比分析头部位置检测系统、车道偏离报警系统、转向盘监测系统、驾驶员警示系统及PERCLOS系统检测疲劳驾驶的优缺点,得出了PERCLOS系统为最优疲劳驾驶检测方法。依据人因工程理论,给出了车体外部警示灯的位置和颜色的设计方案。

In this paper, a Fatigue Driving Prevention System（FDPS） was designed which includes chronograph functions of fa- tigue driving, detection function of fatigue driving, warning light display function of fatigue driving, GPS audio prompt function of fa- tigue driving and Global Positioning System function. The workflow flowchart of the system was drawn. Through comparing and analy- zing the advantages and disadvantages among the Head Position Detection System, the Lane Departure Warning System, the Steering Wheel Monitoring System, the Driver Warning System and the Percent Eyes Closure（PERCLOS）System, it is concluded that the last one PERCLOS system is the best way to test the Fatigue Driving. According to the ergonomics projects themT, a design solution of the outside warning light position and color was made.
