摘要
在对传统动力学临界安全车距数学模型分析的基础上,给出了一种基于驾驶特征安全车距的建模方法,建立了适应驾驶特征的汽车纵向避撞安全车距模型.通过实时检测驾驶员的驾驶行为,建立了驾驶特征辨识模型,将驾驶特征、车况、路况、环境因子等因素融合到数学模型中,最后通过计算分析比较,验证了所建立的数学模型具有较高的准确性和实时性,对汽车主动避撞系统的研究具有较高的应用价值.
A safety distance mathematical model of vehicle longitudinal is estabished based on modeling method of driving characteristic and traditional kinetic analysis of safety distance. Through the real-time detection of driving behavior, the driving characteristics identification model, the driving characteristics , vehicle, road, environment factor and other factors are integrated into the mathematical mode. By calculating and comparing the mathematical model is proven to be higher accuracy and real-time, which has a high application value in vehicle collision avoidance systems research.
