Four wheel steering system for Automobile

Abstract

A Four wheel steering system also known asQuadra steering system.In this paper, bothfront wheel and rear wheels can be steered according to speed other vehicle and space available for turning.Quadra steer gives full size vehicle greater ease while driving at low speed, improvesstability,handling and controlat higher speed.Production-built cars tend to under steer or, in few instances, overseer. If a car could automatically compensate for an under steer overseer problem, the driver would enjoy nearly neutral steering under varying conditions. Four wheel systemsis a seriouseffort on the part of automotive design engineers to provide near-neutral steering.
