Abstract – In today’s world, safe operation of the vehicle
demands that the operator be able to maintain absolute control of the vehicle’s critical operating dynamics: (1) Control of the direction of motion of the vehicle (steering) (2) Control of the velocity of the vehicle, i.e. the ability to slow and fully stop the vehicle (braking). This paper provides an overview of electric assisted vehicular steering including brief description of various conventional systems and the basics of steering; particular attention in addressed to ―Electric Power Assisted Steering (EPAS). Electric power assisted steering has temped automotive engineer since the 1950. Even so, the promise of smaller, lighter, and more efficient systems never quite matched the low cost and performance of hydraulic power assisted steering (HYPAS) advance in microelectronics; however have rekindled interest in EPAS. Motor drive stages, electronic control units and torque sensor can now be manufactured relatively cheaply. These components, coupled with complex control algorithms implemented in software can rival or better the performance and functionality of conventional hydraulic steering systems. Key Words: Need of EPAS, Future Steering Systems, System Structures of Safe Electrical Steering Systems, Electric Power Assisted Steering, Components of EPAS, Selection of Materials, Specifications of Components, Cost Estimation.
and its accessories greatly simplifies manufacturing and maintenance. While offering these benefits, as it does not contain any steering oil, the environment is not polluted both when the steering system is produced and discarded.

1. INTRODUCTION The steering system of an automobile serves two main functions: firstly it allows the driver to make the vehicle follow a desired path or trajectory without requiring excessive physical effort and secondly it assists the driver to judge the driving conditions by allowing some feedback. The later is a subtle aspect of steering system with the driver in the feedback loop striving to minimize the error which the vehicle may have from the desired path. The electric power steering, EPS, does not have any beltdriven steering pump constantly running, so it is lightweight and the motor consumes energy only when the steering wheel is turned by the driver, and this leads to improvement in fuel efficiency. Also, the elimination of a belt-driven pump © 2017, IRJET
