摘要
液压制动系统压力调节装置的调压特性对系统控制性能有着重要的影响,采用稳态压力变化值表征轮缸压力变化率,基于BrakeHydraulics和MK20型压力调节器建立了制动系统仿真模型,推导轮缸稳态压力变化值的计算公式,试验方法测得制动系统阶梯减压控制周期或占空比以及压差与轮缸压力变化率的关系图。计算结果表明:不同占空比下轮缸压力变化率曲线的拐点对应的轮缸压力大体相同,压力变化率与占空比之间的关系呈近似线性。该结果为ABS、ASR、ESP等制动相关控制系统中确定阶梯减压控制占空比提共了依据。
It is very important to control system that the regulation features of hydraulic modulator for vehicle brake system.The pressure variation rate was represented by the stable pressure variation value.Based on the Brake Hydraulics software and the prototype of MK20 modulator,simulation models of brake system are built.The formula to calculate the stable pressure variation value was deduced. Some experiments were carried out to measure the stable pressure variation values under different initial pressures and duty cycles. Calculation result shows that inflection points at different duty cycles appear at the nearly same cylinder pressure,the relationship between the pressure rate and the duty cycle is approximate linear in working pressure range.It is useful to determine the duty cycle of stepped release for brake control system such as ABS,ASR,and ESP etc.
