Abstract
This research offered a comparison of hydraulic (HPS) and electro-hydraulic power steering (EHPS) hydraulic pressure characteristics. The goal is to assess the potential for energy savings if an electric motor replaces hydraulic pressure. The purpose is to calculate the potential energy efficiency if an electric motor replaces hydraulic pressure. For this comparison, HPS and EHPS were both modeled. A PI controller was developed based on these models to regulate the steering wheel position and angular motor speed. In addition, the systems are compared by using the same input reference and transient response system, and the energy consumption is computed. Thus, with the installation of an electric motor in the power steering, it has a good response, functions in an optimal region, stabilizes, and has a 59.95% increase in energy efficiency.
