Two wheel steering mechanism used in common vehicles are having a high turning radius and also difficult in high speed maneuvering. This results in low stability. The four wheel steering mechanism currently used in heavy vehicles, which drives the rear wheels at a same angle as that of the front wheels may result in over steer. So this cannot be implemented in light vehicles. An innovative four wheel steering mechanism which rectifies the above mentioned drawbacks are proposed which serves as our project work. In this steering mechanism the rear wheels are not actually following the front wheels, but turns at a specific ratio. There are two modes of steering mechanism that is for low speed and high speed. At slow speeds, the rear wheels turn in opposite direction of the front wheels. At faster speeds, the rear wheels turn in the same direction as that of front wheels. This steering mechanism improves steering response, increase vehicle stability, improves control etc. In situations like low speed cornering, vehicle parking and driving in city conditions with heavy traffic in tight spaces becomes easy, this is because of rear wheel turn in opposite direction to front wheel. At high speed it increases vehicle stability while maneuvering at and lane changing.
