【摘要】 本文研究了电动液压助力转向控制系统中转向盘角速度、车速和电动机转速之间非线性关系的控制算法。通过在AMESIM中仿真对比表明,运用该算法能够得到较理想的助力曲线,验证了该算法在电动液压助力转向系统中应用的可行性。通过台架实验表明,该系统助力效果明显,控制算法中参数变换对控制系统的影响与实际控制系统控制效果相吻合。更多还原

【Abstract】 This paper studies the control algorithm of electro hydraulic power steering(EHPS) system,which expresses the nonlinear relationship of steering speed,vehicle speed and motor revolution speed.Compared with the other control algorithm,more perfect power control characteristic curve is got by using this improved control algorithm in the EHPS system which is simulated by AMESIM.The feasibility is proved in this control system by above result.The assist result is strong through experiment.The effect of control system changing parameters in control algorithm is same as actual control system.更多还原
