1. A steering control device, comprising:
a first steering control module receiving a steering angle of a steering wheel from a steering angle sensor, calculating a position of a rack corresponding to the steering angle, and transmitting the position of the rack to a road wheel actuator (RWA); and
a second steering control module to which a control right for the first steering control module is transferred when the first steering control module is determined to have a failure,
wherein the first steering control module receives, in an autonomous vehicle mode, vehicle ambient information from a plurality of sensors and calculates the position of the rack according to an ambient context of a host vehicle based on the vehicle ambient information and, in a driving mode, receives the steering angle from the steering angle sensor and calculates the position of the rack corresponding to the steering angle.
