A Comparison Study of Vehicle’s Electro-Hydraulic (EHPS), Electric (EPS) and Hydraulic (HPS) Power Steering System

Year: 2024

Type: conference-paper

Abstract: The aim of this study is to calculate the energy efficiency of an electro-hydraulic power steering system (EHPS), as electric power steering (EPS) system also can be an energy savings solution instead of traditional hydraulic power steering (HPS) system. EHPS consist of electrical, mechanical steering system and hydraulic system. It is an approach to minimize the energy consumption and improve the steering feel of the power steering system of a vehicle. We have developed an electro-hydraulic power steering system and designed a fuzzy-pid controller that can follow the command motor speed. We have calculated, the available motor shaft power to hydraulic efficiency is 53.03%. The mechanical loss includes hydraulics and, rack and pinion loss. This study also focuses on comparison of electrohydraulic (EHPS), hydraulic power steering (HPS) and electric power steering (EPS) system.
