A Research on Impact Compensation Control Strategy of Electric Power Steering System Based on Whole Vehicle Dynamics

Abstract:

In order to improve the vehicles steering performance, based on a whole vehicle dynamics model，the electric power steering system(EPS) control strategy is studied under road surface impact condition. An AIS controller is executed on the output current of assist motor hence further improving control effects. Accompanied the methodology of combining the full vehicle model in CarSim and EPS model in MATLAB, this co-simulation model is verified by test data. By comparison yaw rate and slip angle of the results show that: implementing the control of EPS by AIS compensation strategy is an effective way of enhancing the capability of steering and the stability of operation, which can make it more accurate and flexible.
