基于人-车-路-环境的车辆安全运行区域研究

Vehicle's Safe Operation Region Research Based on Person-Vehicle-Road-Environment

车辆安全运行区域的确定对于提高行车安全具有重要的意义。以高速公路为背景,作者通过综合考虑车辆的行驶状态、驾驶员疲劳程度以及天气状况等因素对车辆的安全运行区域的影响进行了研究。目的是根据车辆当前状态,结合运行参数对危险行驶区域做出警示,减少驾驶员的负担和判断错误。算法部分分别针对跟车模式和超车模式搭建模型,对安全运行距离和区域进行了求取,最后设计了虚拟现实仿真场景对车辆的行驶过程进行了模拟。多次实验表明,本文安全运行区域模型具有很好的稳定性和准确率。

Vehicle＇s safe operation region detenmination has a great significance to improve the traffic safety. Taking highway as a background, this article conducted a research for the vehicle＇s safe operation region through the evaluation factors of automobile＇s transport condition, driver＇s fatigue degree, weather conditions and so on. According to the vehicle＇s current condition and conbined with the operational factor, we aimed to caution the dangerous travel region, to reduce driver＇s burden and error in judgment. The algorithm part aimed at building the models separately by the following operation mode for seeking the safe operation distance and region. At last, tcavel process was simulated. Lots of experiments showed that Hiodel has good stability and accuracy. mode and passing operation a virtual scene of vehicles＇ this safe operation region
