In order to research ATV electric power steering system, the structare of the control system was analyzed; the model of electric power steering system and simplified model of steering power motor for ATV were established. Through the model simulation test results, PID control parameters of EPS were preliminarily determined. The program flow chart of PID control was analyzed, and the PID control algorithm was verified by real vehicle test data. The curve results show ATV EPS motor runs stably and respond quickly. The test results indicate that the test data meet the design requirements and the electric motor control algorithm is feasible.
