六因子调整模糊汽车模型的研究

Study on Vehicle Model Using Fuzzy Control Theory

建立了六因子调整 (自适应 )模糊汽车模型 ,弥补了现有汽车模型都是针对某一具体车型而建立的不足。通过对模型的仿真与试验对比 ,检验了该汽车模型的通用性和正确性 。

In this paper, based on the fuzzy logic control theory, a fuzzy adaptive vehicle model adjusted by six factors was made for study on handling and stability of vehicle. The model overcomes some defects of the existing vehicle model aimed at an idiographic vehicle type. The fuzzy adaptive vehicle model is virtually a fuzzy adaptive control system which is able to adjust its control rule with six amendable factors( α 0,α 1,α 2,α 3,k *,k ** ) and integral factors( k 0,k 1,k 2,k 3 ) according to differing in vehicle construction characteristics and motive states. Therefore, the model can be used for describing the characteristics and the states of all kinds of vehicle. The comparison of the computer simulation of the model with the real experiment of Santana car (330K8DLOLSD1) and BJ212 jeep shows that the model is right and utility.
