1. A steering device comprising:
an electronic control unit electrically connected with a steering wheel of a vehicle;
a road wheel actuator electrically connected with the electronic control unit; and
a display unit electrically connected with the electronic control unit,
wherein
when the vehicle starts, the electronic control unit rotates the steering wheel in one direction or an opposite direction to the one direction by driving the road wheel actuator and measures data of the road wheel actuator to detect an error of the road wheel actuator,
the data of the road wheel actuator includes motor torque data,
the electronic control unit measures the motor torque data and compares the measured motor torque data with an input reference motor torque data,
when the motor torque data is larger than the reference motor torque data by a predetermined size or more, the electronic control unit displays a first error of the road wheel actuator on the display unit,
the road wheel actuator includes an electric assembly and a sensor assembly, and
the first error of the road wheel actuator displayed on the display unit indicates that rust is generated in the electric assembly and the sensor assembly.
