Abstract
A method for steering a four-wheeled vehicle includes: determining a front wheel steering angle; determining a responsive low-speed steering angle of the two rear wheels, the responsive low-speed steering angle being (i) negative when the front wheel steering angle is positive, and (ii) positive when the front wheel steering angle is negative; determining a responsive high-speed steering angle of the two rear wheels, the responsive high-speed steering angle being (i) non-negative when the front wheel steering angle is positive, and (ii) non-positive when the front wheel steering angle is negative; determining a responsive rear wheel steering angle being a sum of the responsive low-speed and high-speed steering angles; and controlling a steering actuator to steer the two rear wheels in accordance with the responsive rear wheel steering angle.
