摘要
本文介绍了电动助力转向(Electric Power Steering,EPS)系统的结构和工作原理,建立了EPS系统数学模型,并与车辆动力学仿真软件veDYNA联合起来,构建了EPS仿真系统。利用该仿真系统对直线型助力特性曲线进行仿真分析,说明该仿真系统可以很方便地对各种路况和工况下的车辆转向进行仿真,可用于EPS系统性能分析以及控制算法验证。
This paper introduces the mathematical model of the electric power steering（EPS） system.Then the EPS simulation system is constructed by combining the EPS system model with the veDYNA（Vehicle Dynamics Analysis） software.The straight-line characteristic curves of the EPS simulation system show that the EPS simulation system work well under all kinds of road conditions and driving situations,and can be used to analyse the EPS system performance and verify the control algorithm.
