| 摘 要： | 解决制动初期的制动力分配难题对汽车安全性具有重要意义。在对汽车制动特性进行分析的基础上,提出含有控制级和协调级的电子制动力分配(EBD)分级控制方法,设计了基于模糊推理的各轮预分配制动力控制策略,并根据各轮参考滑移率对各轮预分配制动力进行调整。利用汽车电子控制单元的嵌入式系统开发平台,在不同条件下进行了汽车EBD与ABS硬件在回路仿真试验试验结果表明,EBD分级控制在制动初期ABS起作用前,能够有效调整汽车制动力分配,提高了整车制动的安全性。

| Abstract: | It is very important to solve the brake force distribution difficulty at the first braking period of automobile.Based on analysis of automobile braking characteristics,a hierarchical control(HC) method of electronic brake force distribution (EBD)was proposed,which included control and coordination levels.Firstly,the fuzzy reasoning was used to calculate pre-distribution braking force of each wheel.Secondly,a whole vehicle coordination rules was proposed to adjust pre-distribution braking force of each wheel... |
