1. A motor control device for a steering system, the motor control device comprising:
a dual winding steering motor unit generating a steering force and a steering reaction force, and comprising a first driving module formed of a first winding and a second driving module formed of a second winding; and
a first electronic control unit controlling an operation of the first driving module, and a second electronic control unit controlling an operation of the second driving module, on the basis of steering information obtained by a driver's steering wheel manipulation,
wherein any one of the first electronic control unit and the second electronic control unit determines a failure mode on the basis of failure information when the failure information about any one of the driving modules controlled by the corresponding electronic control unit is acquired, and then transmits the failure mode to a remaining electronic control unit,
wherein the remaining electronic control unit selects a compensation value for the failure mode to control an operation of a remaining driving module according to the compensation value,
wherein the first electronic control unit comprises a first memory unit storing a lookup table for a plurality of failure modes to select the compensation value, and
wherein the second electronic control unit comprises a second memory unit storing a lookup table for a plurality of failure modes to select the compensation value.
