Electric Power Steering Concepts

The video tutorial explores the evolution of steering systems, from manual to hydraulic and finally to electric power steering. It highlights the inefficiencies of hydraulic systems and the advantages of electric power steering, such as improved efficiency, addressability, accuracy, and compactness. The tutorial also discusses the challenges faced by electric systems and the future potential of steer-by-wire technology.
