Abstract

Disclosed are a steering control device of an autonomous vehicle, an autonomous vehicle having the same, and a steering control method of an autonomous vehicle. The steering control method comprises receiving a position of an autonomous vehicle, and a first heading angle of the autonomous vehicle with respect to the north; calculating a second heading angle of the autonomous vehicle toward a tracking waypoint based on the position of the autonomous vehicle, and computing a rotation radius of the autonomous vehicle with respect to the tracking waypoint; calculating a yaw rate based on a speed of the autonomous vehicle and the computed rotation radius, and generating a steering command corresponding to the calculated yaw rate; and compensating for the steering command based on the first and second heading angles.
