摘要
在6DOF运动平台系统基础上,集成汽车半物理模型、NDI位置跟踪器、工业相机等硬件,建立了支持驾驶员疲劳测试的驾驶模拟器系统。系统采用Matlab/Simulink建立汽车物理模型进行运动学/动力学仿真;光学跟踪器对驾驶员头部运动信息进行采集;PVT测试记录驾驶员反应时间;并利用网络进行仿真同步。实验验证表明,开发的驾驶模拟器系统可以逼真的模拟驾驶过程,并采集相关疲劳参数,为驾驶疲劳测试提供了一种有效的实验工具。
A driver fatigue testing simulating platform is established based on 6DOF motion platform and integrated with the semi- physical car model, NDI position tracking system, industry camera and so on. A kinetic car model is built up with Matlab/ Simulink to simulate the car’s kinetics and dynamics, and the driver’s head position is captured by the NDI device, driver’s responding time is acquired by the PVT testing, all the sub-system are synchronized through network. Experiment results shows that the fatigue driving simulator can simulate driving process realistically and acquire fatigue-related parameters.
