摘要

摘要: 在分析传统液压制动系统踏板特性的基础上,以试验得到的踏板特性为目标,设计了以弹性元件和液压单元为基本模拟单元的踏板模拟器;分析了"制动感觉"指数(BFI)评价指标;以AMESim和Matlab/Simulink为仿真平台,建立踏板模拟器仿真模型并进行了仿真计算.计算结果表明,模拟器输出的踏板反力随踏板行程的增加而增大,其踏板特性能够跟随目标踏板特性而变化;改变弹性元件的刚度和液压缸的压力,可以得到不同的踏板特性;对3种不同弹簧刚度的模拟器"制动感觉"进行评价,BFI达到92.4分,具有良好的制动感觉;通过调整模拟器参数,可以适应不同的车型或满足不同的驾驶员需求.

Abstract: The pedal characteristic from experiments for target, a pedal simulator with elastic components and hydraulic unit as the basic simulation unit was designed, which based on the analysis on the pedal characteristics in traditional hydraulic braking system. The "breaking feeling" evaluation index was analyzed. The simulation model of pedal simulator was established by using AMESim and Matlab/Simulink. The pedal characteristic was simulated. The simulation results show that, the pedal reaction force increases with the increase of the pedal stroke, the pedal characteristics could be able to change following the target pedal characteristics; the different pedal characteristics could be obtained by changing the stiffness of elastic component and the pressure of hydraulic cylinder; the "breaking feeling" index was evaluated on three different simulators, and the maximum braking feel index value is 92.4 points, which means a "good" brake feeling. The pedal characteristics could adapt to different vehicle or meet needs of different drivers by adjusting the parameters of simulator.
