    摘要:

    以汽車電子穩(wěn)定性程序（ESP）液壓控制單元的回油泵、高速開關閥等關鍵部件為研究對象，推導其數(shù)學模型，利用AMESim、Matlab軟件建立ESP液壓系統(tǒng)回油泵、高速開關閥運動的聯(lián)合仿真模型，通過仿真得出這些液壓元件參數(shù)對主動增壓下制動輪缸壓力調節(jié)的影響，為提高回油泵效率、實現(xiàn)高速開關閥的線性控制功能提供參考依據(jù)。

    Abstract:

    Taking the piston pump and high speed on-off valve, the crucial parts of automotive electronic stability program (ESP). Their mathematical models were established. Besides, the co-simulation model of ESP hydraulic control unit (HCU) was built up by AMESim and Matlab, which was also verified by test. The simulation model described the motion intrinsic characteristic of the piston pump and high speed on-off valve. Consequently, the effect of those components’ parameters on the adjustment of braking pressure during active boosting was analyzed. The result can provide references for the design and development of ESP, especially for improving the efficiency of the pump and the linear control performance of the high speed on-off valve. 
