一种汽车制动不同步的方法分析研究

Analysis and Research on Automobile Braking Not Synchronous Control Method

针对汽车制动时前后轮制动力分配不均产生的制动不同步问题,先对汽车制动时进行受力分析,得出制动时不同步的原因及结果。然后对不同步控制方法的影响因素和方法的分析,得出几种典型控制技术。最后在分析结果的基础上,通过MATLAB进行建立变速器变速运动规律模型建立,以及模糊控制模型、参数调试和仿真。最后,着重分析汽车的变速器调节制动力分配后的制动过程,得到良好的ABS模糊制动控制效果,为进一步制动控制研究打下良好基础。

The research is focused on the uneven distribution of the front and rear wheels braking when the car brake braking sync problems. First of all,the reasons and results of synchronous when braking is gotten through the analysis of car braking force. Through analyzing the influence factors and methods of synchronization control,some technologies are gotten. And then,speed change rules are found,at the same time,modeling,parameter debugging and simulation based on the analysis of results are also set in MATLAB environment. At last,emphatically analyzed joined the transmission after adjusting the braking force distribution of braking process,and the fuzzy control results of ABS braking system are good for further research of vehicle braking.
