Research Of Electric Power Steering System Of Hafei Cars

This paper is based on car electric power steering system of Hafeiauto.I mainly do thefollowing research work：Review the development of car electric power steering technology and the advantagesof electric power system. State the background and purpose of this paper.Simply discusse the structure and principle of electric power steering system,analyzing the performance characteristics of electric power steering system. State thedesign of the assembly parts of car electric power of Hafeiauto. Based on the new humanoriented design, steering mechanism can be designed according to fold up and deformationwhen collision happen to reduce the damage of personnel, improve vehicle passive safetyperformance.Controller is designed using the reliability concept, with abnormal warning and failuretreatment function to improve the maximum security of the system.Controller has frictioncompensation logic control, damp compensation, and return control function to improve theability of the steering system to adapt to all kinds of steering conditions.Briefly state the experiment of steering system assembly and controller, to guaranteethe reliability of steering system. Evaluate the characteristics of a full speed car boostersystem of Hafeiauto.Testing the performance of electric power steering system to satisfythe design requirements based on low and high speed.Analyse and verify the car electric power steering system of Hafeiauto.Optimizedesign and accumulate experience. The research of this paper has help to the design ofother models of electric power steering system.
