| Abstract: | The simulation models of EPS system,H.B.Pacejka tyre and 3-DOF vehicle were built based on Matlab/Simulink.Then the integrated simulation model was built by the system integration method,the impact of EPS system on the transient state response quality of steering wheel was analyzed and the assistance control strategy was validated.The results show that the integrated simulation model has better dynamic simulation feature,EPS has better stability and the control strategy can coordinate successfully the contradiction between steering agility and road feel. |
