Model-based development for an electric power steering system

Abstract

A model-based development method for electric power steering (EPS) system has been explored. A practicable model for the EPS system has been established in a full vehicle mechanical system environment. The performance of the electric control system of the EPS system has been evaluated in this static analysis environment. The model has then been used in a dynamic test environment based on dSPACE hardware and software, including Software-in-the-Loop and Hardware-in-the-Loop. The test result validates the simulation model, and shows that this development method can be used to evaluate the conceptual design of the EPS system as well as the control software design and testing.
