Electrical Power Assisted System Hardware in the Loop(HIL)Simulator Design

To deal with the problems of high cost and great difficulty in the current development of HIL simulator for Electrical Power Assisted system（EPS）,this paper has designed and conducted some experimental verification by building hardware in the loop simulator and adopting simulation methods.By using the modular technology of Virtual C＋＋ and adjusting real-time parameters on-line and hardware in-the-loop simulation,this paper indicates that the device works well in the function of in-the-loop simulation,and it is capable to simulate all kinds of EPS working conditions for the actual tests,which provides basis and reference for real tests and products development.
