1. A steering assist device, comprising:
an input-side steering control module controlling an input-side steering actuator to assist an input-side mechanism connected with a steering wheel;
an output-side steering control module controlling an output-side steering actuator to assist an output-side mechanism mechanically separated from the input-side mechanism and connected with a wheel;
an output-side linear position sensor providing a linear position sensing value of a sliding bar provided to be axially slidable inside a housing and connected with a wheel; and
an output-side steering motor position sensor providing the position sensing value of the output-side steering motor,
wherein the output-side steering control module checks whether each of the linear position sensing value of the sliding bar and the position sensing value of the output-side steering motor is normal, compares a normal linear position sensing value of the sliding bar with the normal position sensing value of the output-side steering motor to thereby verify the validity for the normal position sensing values, and controls the output-side steering motor based on a target position value of the sliding bar received from the input-side steering control module and one normal position sensing value of the normal linear position sensing value of the sliding bar and the normal position sensing value of the output-side steering motor verified for validity.
