利用预瞄跟随理论、模糊决策理论和非线性系统描述函数法建立了一个驾驶员速度控制模型,即驾驶员最优预瞄纵向加速度模型。仿真结果表明,该模型通过对驾驶安全性、合法性、轻便性、驾驶员自身滞后特性及汽车动力学系统强非线性特性的考虑,可以有效地模拟驾驶员控制汽车速度的行为特性,为人-车-路闭环系统中速度控制研究提供了一条可行途径。
Using preview-following theory, fuzzy decision theory and nonlinear system description function method, a driver’s speed control model is established, which is the driver’s optimal preview longitudinal acceleration model. The simulation results show that the model can effectively simulate the driver’s behavior of controlling vehicle speed through consideration of driving safety, legality, portability, driver’s own hysteresis characteristics and strong non-linear characteristics of vehicle dynamics system. Vehicle - road closed-loop system speed control provides a viable way.
