ELECTRONIC STEERING APPARATUS FOR VEHICLE AND METHOD OF CONTROLLING SAME

Disclosed herein is an electronic steering apparatus for a vehicle. The apparatus includes a first driver and a second driver configured to drive a drive motor by being supplied, respectively, with electric power from a first electric-power source and a second electric-power source, a first sensor and a second sensor configured to recognize states, respectively, of the first electric-power source and the second electric-power source, and states, respectively, of the first driver and second driver, a first output controller and a second output controller coupled to a vehicle control device, and a first processor and a second processor operatively coupled, respectively, to the first and second drivers, the first and second sensors, and the first output and second output controllers. The processors are configured to determine whether electric-power states of the first electric-power source and the second electric-power source are normal, by comparing the electric-power states with each other.
