In the standard 2-wheel steering system, the rear wheel set is always directed forward and does not play an active role in steering control. While in the 4-wheel steering system, the rear wheels play an active role for steering, which can be guided high as well as low speeds. Production cars are designed for under the ox and rarely make over the ox. If a car could automatically compensate for a steering / overflight problem, the driver would enjoy an almost neutral steering under varying operating conditions. Also in situations such as low speed curves, parking of vehicles and driving in city conditions with heavy traffic in confined spaces, driving would be very difficult due to the greater wheelbase and track width of the sedan. Therefore, there is a requirement for a mechanism that results in a smaller turning radius.
The 4-wheel steering system is used in vehicles to achieve better maneuverability at high speeds, reducing the radius of the car's turning circle and reducing steering effort. In most active 4-wheel steering systems, the guiding computer or electronic equipment plays an important role, in our project we have tried to keep the mechanism as mechanical as possible which can be easy to manufacture and maintain.
