초록 The development of the steering feel performance of a vehicle is primarily carried out by tuning the motor-driven power steering(MDPS). The motor-driven power steering provides a lot of parameters for developers in order to maximize the steering feel performance. However, it needs a lot of time and effort, so the development efficiency is not favorable. In order to improve the development efficiency, this paper proposes an optimal design method and process of MDPS logic as follows. First is the definition of quantitative targets for multiple tests that may indicate steering feel performance, second is the construction of the vehicle and control model for checking the steering feel performance, and third is the process proposal to optimize the MDPS logic parameters. This method and process is validated through the comparison of the simulation and test results.
