基于驾驶行为及意图的汽车主动安全技术研究

Study on automotive active safety technology based on driving behavior and intention

针对国内汽车主动安全技术研究的现状,提出了基于驾驶员行为及意图判断的汽车主动安全研究方法,在此汽车主动安全系统中利用采集到的驾驶员各种操作信号及环境信息,进行驾驶员的驾驶行为及意图分析。根据驾驶员的各种操作信息对常见驾驶行为及意图判断的权重的不同,建立了用于判别典型驾驶行为及意图的权重矩阵。通过MATLAB软件编程仿真,建立了八种典型驾驶状态下权重判断矩阵,仿真表明,该权重矩阵设计合理,可以准确地判断和识别出典型的驾驶行为及意图,为未来汽车主动安全技术的研究提供了一种有效的方法。

To the status of domestic automotive safety technology research,the vehicle active safety research method that was based on the identifying of driver behavior and intention was proposed.it safety system,the analysis of driving behavior and intention was made by collecting a variety of driver＇s operating signal and environmental information.The weight matrix for identifying the typical driving behavior and intention was built according to the different proportion of variety operating information on identifying common intention of driving behavior and intention.Through programming emulation with MATLAB,the weight matrix under the eight typical given state of driving was established.The emulation indicates that the weight matrix was designed reasonably.The matrix can identify the driving behavior and intention exactly.It offers an effective method for researching automotive active safety technology.
