1. An electronic steering apparatus for a vehicle, comprising:
an input module configured to receive signals indicating a vehicle state and a steering state;
a first driving module configured to drive a reaction motor of a steering wheel;
a second driving module configured to drive a steering motor that steers a controlled wheel;
a memory in which an execution program for steering control is stored; and
a processor operatively coupled to the input module, the first driving module, the second driving module, and the memory,
wherein the processor, when executing the program, controls the first driving module and the second driving module to generate reaction torque on the steering wheel and steering torque on the controlled wheel, respectively, so that the steering wheel and the controlled wheel are aligned based on the vehicle state and steering state, and
wherein the processor, when executing the program, further controls the second driving module by limiting the steering torque when an interference state of the controlled wheel is determined, and drives the first driving module to generate the reaction torque based on a limit value of the steering torque;
wherein the interference state of the controlled wheel is determined as a state in which locations of the steering wheel and the controlled wheel have not been changed and a steering end has not been reached.
