摘要
从驾驶员视角出发,构建汽车行驶轨迹跟踪数学模型,运用Matlab/Simulink工程软件和C语言,建立驾驶员-环境-汽车闭环系统仿真模型。利用Matlab平台遗传算法(GA)仿真包,以驾驶员道路跟随精度、车辆侧向加速度和转向盘忙碌程度所构成的综合评价指标为目标函数进行分析,获得模型参数最优值。模拟和试验结果表明:模型设计合理,能较好地反应熟练驾驶员正常驾驶特征。
In this paper, a driver model based on the driver＇s heading angle was set up, and with the application of Matlab/Simulink and C language, the driver-environment-vehicle closed-loop simulation model was developed. The model was simulated with the genetic algorithm （GA） toolbox on the Matlab platform. The model parameters＇ optimal values were obtained by an object function of the genetic algorithm, which comprehensive evaluation index considers the task performance, driver＇s physical workload and mental pressure. The simulation and experimental results showed that the design of model is reasonable, and the model can describe the driving character of the sophisticated driver.
