摘要
基于BrakeHydraulics软件库和MK20型压力调节器建立了液压制动系统仿真模型,并在此基础上定量分析了制动系统阶梯减压控制周期或占空比和压差与轮缸压力变化率的关系,为ABS、ASR、ESP等与制动相关的控制系统中确定阶梯减压控制占空比提供了依据。
Based on RT BrakeHydraulics software library and MK20 pressure modulator,a simulation model for hydraulic brake system is built,based on which a quantitative analysis is conducted on the relationship among stepped release control cycle （or duty cycle）,pressure difference and the changing rate of wheel cylinder pressure,so providing a basis for determining the duty cycle of stepped release control for braking-related control systems such as ABS,ASR and ESP etc.
