In today’s world due to Modern development and economical progression there is increase in number of cars on roads. Because of increase in number of cars, car parking is the major problem faced in most parts of the country. In a typical front wheel steering system the rear wheel do not turn in the direction of the curve . In situations like low speed cornering, vehicle parking and driving in city conditions with heavy traffic in tight spaces, high speed lane changing would be very difficult due to vehicle’s larger wheelbase and track width which brings high inertia and traction into consideration. Due to this the efficiency of two wheel steering reduces. Hence there is a requirement of a mechanism which result in less turning radius and increase stability and it can be achieved by implementing four wheel steering mechanism instead of regular two wheel steering. Implementing 4WS allows the vehicle to turn in a significantly smaller radius, sometimes judgmental for large trucks or vehicles with trailers. 4-wheel steering is a system employed by some vehicles to improve steering response, increase vehicle stability while steering at high speed and to decrease turning radius at low speed. It also helpful in avoiding skidding as well as parking problems occurs in metro cities, highways and in rural areas.
