Abstract: The disclosure relates to a steering control device and method. Specifically, according to the disclosure, a steering control device comprises a first steering control module controlling a first reaction force motor to generate a reaction force torque for a steering wheel through a first inverter and a second steering control module controlling a second reaction force motor to generate a reaction force torque for the steering wheel through a second inverter. The first steering control module or the second steering control module generates the reaction force torque by conducting one of the first inverter and the second inverter when the first inverter and the second inverter fail.
