摘　　要：为研究液压控制系统的工作过程及与整车的匹配,基于AMEsim/Matlab联合仿真技术,在AMEsim中建立了ESP液压系统模型,对其进行动态特性分析,将液压系统模型与Mat-lab中建立的整车模型及控制器连接建立了联合仿真模型,对其控制效果进行联合仿真。结果表明:通过对液压系统参数的合理匹配,ESP可以对汽车进行较好的控制,提高汽车的操纵稳定性。As the actuator of the vehicle ESP,the hydraulic control device is a high-speed response system.It is of great significance for ESP control effect to study of the actuator＇s dynamics characteristics.For research on the working of the hydraulic device and its reasonable matching with vehicle dynamics model,based on co-simulations of AMEsim and Matlab,ESP hydraulic device model is built with AMEsim and the analysis of its dynamics characteristics is done.The hydraulic device model is co-simulated with dynamics model and controller built in Matlab.The results show that ESP can control the vehicle well and the stability of the vehicle is enhanced through matching the parameters of the hydraulic device reasonably.
