Abstract

An Electric Power Steering (EPS) System will be considered in this paper. We will discuss electrical power steering (EPS) design by utilizing information related to road surface conditions. Information regarding varying road surface conditions includes both pertinent information and ineffective information, which can be separated by frequency. These frequencies can be utilized in designing an EPS system more effectively in comparison to a conventional hydraulic power steering system. a means of combining EPS design with information based on road surface conditions to create a robust EPS system has been achieved. Furthermore, for this purpose, mechanical element designs such as a reduction gear, rack and pinion, and torque sensor are also described. The feasibility of our approach to design is also confirmed by experiments.
