摘　　要：结合EPS结构特点和整车横向动力学特性，在Matlab／Simulink环境下构建集成EPS系统模型、UniTire轮胎模型以及三自由度整车模型的集成仿真模型。在此基础上分析EPS系统无助力控制及有、无PID控制的仿真效果，结果表明集成仿真模型具有较好的动态模拟特性，PID控制能够满足控制需求并具有较好的稳定性。Based on the structure characteristic of Electric Power Steering System（EPS） and vehicle lateral dynamics, the EPS integrated simulation model was built which integrated by the models of general EPS system, H. B. Pacejka tyre and 3-DOF vehicle by Matlab/Simulink. On this basis, the simulation results of EPS system with no power motor, no-PID control assist and with PID control assist were analysed. The results show that the integrated simulation model has better dynamic simulation features and PID control can meet the control requirements and has good stability.
