Apparatus and method for reducing vibrations of electronic power steering apparatus

An apparatus for reducing vibrations of an electronic steering apparatus, comprising:

• a vibration filter unit which extracts a steering vibration signal that is a radio frequency component of a torque signal transmitted from a torque sensor;
• a signal generation unit which generates a reference signal based on one of a wheel speed and a wheel vibration number transmitted from a sensor mounted in a vehicle;
• an adaptive filter which receives the reference signal generated by the signal generation unit and generates a current control signal;
• a motor which receives the current control signal;
• and
• an error unit which stores a steering vibration component value generated based on the steering vibration signal and the current control signal applied to the motor, wherein the steering vibration component value stored in the error unit is provided as feedback to the adaptive filter to update the adaptive filter with a coefficient,
• wherein the error unit provides the steering vibration component value as feedback to the adaptive filter so that the steering vibration component value becomes ‘0’ or approaches ‘0’.
