Automotive electric power steering system is a new steering system , compared with previous automotive steering system with active safe , light weight , good road feel , energy saving and environmental protection , turning light and many other advantages . Very much in line with the modern automotive electronics development , electronics , intelligence requirements , is gradually replacing the traditional hydraulic power steering system , vehicle development technology hotspot . Topic First -depth analysis of the basic structure of the EPS system , the establishment of a mathematical model of the electric power steering system , the model based on the analysis of the characteristics of electric power steering system booster , determine the target current control program , and help features simulation . Then , according to the requirements of the design parameters , the electric power steering system of the main portion of the motor , the torque sensor , a vehicle speed sensor , the speed reduction mechanism , etc. analysis and selection , and to conduct a study of the control circuit for EPS system , the design of the motor drive control circuit , and CATIA three-dimensional modeling of the system . MicroAutoBox controller to establish a bench , power steering control strategy is developed based on MATLAB / simulink establish rapid control model , turn in situ experiments in the experimental stage , the control strategy was validated .
