The steering efforts significantly influences vehicle handling and driver comfort, making it a critical parameter in automotive design. This research focuses on analyzing and optimizing steering effort in both mechanical and hydraulic power steering systems. The study investigates the relationship between steering effort and factors such as vehicle speed, steering angle, and axle load. Emphasis is placed on differentiating the effort required during low-speed maneuvers, such as parking, versus high-speed driving conditions. Mechanical steering systems are assessed in terms of direct driver input and torque requirements, while hydraulic systems are evaluated for their assistance mechanism through pumps and fluid pressure. Experimental and simulation-based methodologies are used to quantify steering effort, followed by optimization strategies to reduce physical demand on the driver without compromising steering feel or vehicle control. The results highlight the advantages and limitations of each system, offering insights into design improvements for enhanced performance and driver ergonomics.
