Abstract
Automotive steering systems have gone through the transitions from non-assisted type to hydraulic-assist type, and then, to electric-assist type for its assist. Still, some issues are remaining to adopt the electric-assist type steering to heavier duty vehicles. Therefore, we are depending more on the technology of electrically controlled hydraulic power steering.
This paper covers the technical trends in regard to power steering (PS) energy saving, especially focuses on electronic control of hydraulic PS.
