Electric Hydraulic Power Steering System

Electronic power steering system it is the latest type of power steering system in which the hydraulic system from the hydraulic power steering is completely replaced with electric motors and electric sensors instead of using hydraulic force the motor driven by the vehicle s battery is used to apply force on the steering gear and torque.

Electric hydraulic power steering system. Japanese auto major nissan has developed world s first and very innovative power steering system for its upcoming hybrid car nissan fuga hybrid which is due for its launch in year 2011. Electric power steering eps or motor driven power steering mdps uses an electric motor rather than hydraulic system to assist the driver of a vehicle. They all work together to create the hydraulic power which the steering wheel needs to turn so easily. The steering torque sensor measures the steering force applied by the driver and enables sensitive control of the electric steering support.

How hydraulic power steering works. By providing power assist via hydraulic pressure this system delivers a naturally smooth steering feel and thanks to the flexibility of control allowed by electric power offers more precise steering power characteristics. Earlier it did not have any difference in steering response with speed of the car but the new age of hydraulic power steering are speed sensitive and work better than the older hydraulic. This system is comprised of various components and parts such as a pump pulley drive belt hoses and power steering fluid.

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. The electric power steering system is typically part of the hi speed can bus on the vehicle. Hydraulic power steering is a primitive technology used for decades and has improved a lot with time. It also improves fuel economy since the electric powered pump operates only when steering assist is needed.

Hydraulic power steering is one of the earliest forms of power steering technology. We have already covered technical article on the two most popular power steering systems electric power steering vs hydraulic power steering. It serves the same function as a spool valve in a hydraulic power steering system. Understanding general details related to widely used and popular hydraulic power steering system will help to troubleshoot and maintain the system for reducing expensive damage.
