Abstract
A four-wheel independent steering system and a method of controlling the four-wheel independent steering system. The four-wheel independent steering system includes a front/rear-wheel-angle-ratio calculation unit to calculate a ratio Kss between front and rear wheel angles that allows a body slip angle to converge to '0' and allows a yaw angle and a yaw rate to maintain target values, and a control unit to perform four-wheel steering control based on the ratio Kss between the front and rear wheel angles.
