Abstract
The steering system includes: a first steering device to-steer left and right wheels in a mechanically associated manner by changing an angle of left and right chassis frame components; and a second steering device to drive a supplementary turning actuator to change angles of the wheels relative to the chassis frame components. The second steering device includes a supplementary turning control section to perform a control to cause turning by a steering angle that is a difference between a steering angle determined by a numerical model of vehicle motion on the basis of the steering command angle and the vehicle velocity and an actual steering angle.
