This paper, while introduce development trend, basic structure and working principle for auto power steering system, is analyzing on characteristic curve of steering force in steering system. The paper proposed a control mode for electric power steering system, which, analyzing control strategy for power steering system based on control module, providing a new design thought and method for electric power steering system using MATLAB simulation analysis for steering dynamic features of electric power steering system and affects of road obstruction on steering system performance.
Research on control strategy of the vehicle electric power steering system based on brushless DC motor
