摘　　要：为分析某型乘用车电动液压助力转向系统(EHPS)液压泵驱动电机转速特性,设计和搭建了电动液压泵转速、车速、方向盘角速度、方向盘力矩及车身侧向加速度车载数据采集系统。设计了多种典型驾驶试验工况和试验步骤,进行了实车试验,获得了较为全面的电动液压助力转向系统实时控制数据。通过对试验采集数据的处理,得到了非转向及转向工况下电动液压泵目标转速特性图;分析了不同操纵工况下电动液压泵目标转速的控制特点和控制效果,为电动液压助力转向系统的设计提供参考。For the analysis of the motor speed characteristics of electro-hydraulic power steering system（EHPS）,this paper design and build a test data acquisition system for collecting the motor-pump speed,car speed,steering wheel angular velocity,torque and the vehicle body lateral acceleration data. To get more comprehensive data of the motor-pump speed,variety of typical driving conditions and test procedure are designed,and carried out. Through the data processing,motorpump target speed graphs under steering and straight line running conditions are obtained. The characteristics of the target speed graphs and their control effects are discussed,which provide a reference for the design of electro-hydraulic power steering system.
