基于Speed Dreams的驾驶员应激响应分析系统

为了研究应激状态下的驾驶员行为,提出了一种驾驶员应激响应分析系统.硬件系统以罗技赛车方向盘为基础并进行相应的机械改造,软件系统采用Speed Dreams引擎创建典型应激场景；采用Joystick监控方法以及多线程通讯技术,高速动态采集并记录驾驶行为.对采集数据进行滤波、去噪、微分等处理和分析后,得出驾驶员的应激响应时间及数据间的相关规律.该研究成果可以为应激状态下的驾驶员行为研究提供可靠的数据支持.

Drivers' critical response analysis system based on speed dreams engine

In order to research drivers’ behavior under emergent situations,a drivers’ critical response analysis system is presented.The hardware system is a Logitech racing wheel with corresponding mechanical reconstruction.The software system creates typical critical scenes with Speed Dreams and high-speed dynamic collects and records driving behaviors with Joystick monitor method and multi-thread communication technology.Then we obtain drivers’ critical response time and summarize relevant laws of data after doing filtering,noise reduction,differential and other data processing and analysis.The results provide reliable support for further research on driving behavior under emergent situations.
