摘要
针对串联主缸踏板行程模拟器展开研究,分析了在正常工况和前、后腔分别漏油工况下踏板力的传递途径、踏板感觉及其影响因素,采用模糊自适应PID控制方法对影响参数进行在线自整定,以控制电磁阀来建立良好的模拟制动感觉。最后,采用Matlab-AMESim联合仿真,研究了踏板行程模拟器的主要参数变化时对踏板力与行程特性关系的影响,仿真实验结果表明,本文控制方法可使制动踏板特性在正常工况和前、后腔漏油工况下均满足设计要求。
The tandem master cylinder pedal stroke simulator is studied in this work. First, the pedal force transmission ways under normal condition and oil leakage condition of the front and back cavities, and the parameters influencing the pedal feeling are analyzed. Then, the fuzzy adaptive PID control method is adopted to set the influencing parameters online, thus to control the solenoid valve to create a good simulation brake feeling. Finally, the effects of the main parameters of the pedal stroke simulator on the pedal force-stroke relationship are investigated by Matlab-AMESim co- simulation. Results show that the proposed control method enables the brake pedal to meet the design requirements both in normal condition and in oil leakage condition of the front and back cavities.
