汽车防抱自适应模糊控制方法

Adapting Fuzzy Control for Anti-lock Braking System and its Experiment of Rapid Control Prototyping

为了改善制动防抱系统的制动性能和制动踏板感觉,提出了一种基于相对滑移率和相对车轮加速度的汽车防抱自适应模糊控制方法,利用dSPACE快速控制原型系统将该方法在实车控制中予以实现,并进行了实车试验。试验结果表明,该控制方法能够达到理想的控制效果,轮速和轮缸制动压力波动幅度比传统控制方法(逻辑门限控制方法)减小了50%,且没有出现制动抱死现象。

In order to improve the braking performance of the ABS system and the feeling of the brake pedal, an automobile ABS fuzzy control based on relative wheel slip ratio and relative wheel acceleration was introduced, and its application on the vehicle control system by dSPACE RCP （Rapid Control Prototyping） system, and the RCP experiment on real automobile were implemented. The experiment results show that this control method could achieve an ideal control effect and superior 50% in lessening fluctuation amplitude of wheel speed and wheel braking pressure to the control method of logic limits, and there is no occurrence of braking lock. 1 tab, 9 figs, 8 refs.
