Hydraulic Control Unit Modeling of Electronic Stability Program Based on AMESim

Article Preview

Abstract:

Hydraulic Control Unit(HCU) is the actuator for braking force distribution of Electronic Stability Program(ESP), the modeling and simulation of HCU have significant impact for ESP control logic research. According to the research on scheme of HCU hydraulic system, HCU model is establishes based on AMESim, and calibrates the property parameters of hydraulic component. A test platform for ESP system research is built. By comparison of results between test and simulation, the HCU model can well describe the property of HCU of test car environment, provide accurate actuator model for ESP development simulation and ESP pressure estimation algorithm.
