Power-assisted rack and pinion steering. Also known as motorized power steering (MDPS), it uses an electric motor to assist the vehicle's driver. Adjusting the steering feel for a new car required varying the fluid flow selectively by adjusting valves. The benefits of providing assist electrically are multifold: it improves fuel economy by a few percent, as the electric motor only draws power when needed; it eliminates the hydraulic fluid maintenance mentioned above; and it also enables a variety of features. Electric power steering systems are relatively simple and consist of just a few components. The 'feel' Where hydraulic power steering systems used pressurised fluid divided between two chambers in the steering gears cavity to provide steering assistance, most electric setups use an electric motor mounted to the side of the steering rack that drives a ball-screw mechanism that engages a spiral cut in the outside of the steering rack. Another positive of electric setups is ever-so-slightly increased fuel economy. What are the benefits of electric power steering? Sensors detect the position and torque of the steering column, and a computer module applies assistive torque via the motor, which connects to either the steering gear or steering column.
