Abstract
An electronic steering system is disclosed. The electronic steering system comprises a steering feedback actuator comprising a motor connected to a steering wheel and configured to generate reaction torque for steering feel, and an inverter configured to control the motor. The system includes a plurality of resistance units, each having one end connected between the motor and the inverter, and a plurality of switching units, each having one end connected to different another ends of the resistance units, and each having another end mutually short-circuited or connected to ground. The plurality of switching units become a closed state when there is an abnormality in power supply to the steering feedback actuator.
