智能驾驶员模型用于自由流和拥堵流状态下的行驶车辆行为的描述,具有物理意义明确,模型参数少等优点。利用Excel软件的迭代计算和动态模拟功能实现了该模型的计算机仿真,动态的实现了车辆的跟驰行驶过程。仿真中实现模型参数化,可以观察到各种参数对模型的影响,对车辆跟驰过程中车辆运动参数的变化和模型的特征进行分析带来便利。仿真方法中各种公式和数值计算过程清晰可见,而且不需要开发者有计算机编程经验,也可对其他类型的跟驰模型仿真、验证及实验教学提供参考。
The intelligent driver model is used to describe the vehicle behavior under free and jammed flow conditions with the advantages of clear physical meaning and less model parameters. The computer simulation of the model is realized by iterative calculation and dynamic simulation function of Excel software, which dynamically implements the following process of the vehicle. In the simulation, the parameterization of the model can be realized, and the influence of various parameters on the model can be observed. It is convenient to analyze the change of the vehicle motion parameters and the characteristics of the model during the following process. The simulation method in a variety of formulas and numerical calculation process is clearly visible, and does not require developers to have computer programming experience, but also to other types of car model simulation, verification and experimental teaching to provide a reference.
