Disclosed are a steering control device in an autonomous driving system and a method thereof, which allow manual vehicle operation of a driver without canceling autonomous driving in an autonomous driving situation. The steering control device in an autonomous driving system comprises: an impedance pinion angle generator calculating a steering following angle (x_3_i) in which a following error caused by driver torque is reflected based on an error relation formula between a given following steering angle (x_3_d) and a steering wheel angle in an autonomous driving mode; and a following controller calculating torque control input to allow a steering angle (x_3) of a vehicle to follow the steering following angle (x_3_i).
