为了使驾驶员获得良好的踏板感觉，通过分析影响踏板感觉的主要因素，并依据制动感觉评价指数中相关参数，设定了理想状态下踏板力、踏板行程与制动减速度三者间的相互关系。提出了一种用于电液复合制动系统的踏板模拟机构，建立了模拟机构的数学模型，分析了其中弹簧刚度和活塞面积等对踏板力与行程间关系的影响。根据理想的踏板力与行程的关系，结合样车制动系统，设计踏板模拟机构具体参数值。搭建踏板模拟机构AMEsim模型，进行仿真分析。结果表明：该踏板模拟机构在相同踏板力下得到的行程与理想行程相对差值控制在10%以内，可认为该机构能够反馈良好的踏板感觉。通过对所提出踏板模拟机构建模与仿真分析，为设计可反馈良好制动感觉的踏板模拟机构提供了设计依据。

In order to guarantee that the driver could acquire good pedal feeling and the ideal rela-tionship of pedal force, pedal stroke and braking deceleration was obtained by analyzing the factors that affect driver's braking feel according braking feel index valuation. A new structure of brake ped-al simulator was proposed and the mathematical model was established for analyzing the relationship of pedal simulator's parameters and the pedal feeling valuation. According to the vehicle's brake structure parameters, the spring stiffness and piston area of the simulator was matched and designed. The dynamic model of brake pedal simulator mechanism was established by AMESim software. The result of simulation shows that the proportional error between simulation and ideal pedal stroke at the same pedal force can be controlled by less than 10%which could be regarded as having ideal braking feel to the driver. This theory could be used to design pedal simulator mechanism of electro-hydrau-lic braking system with a good braking feel.
