The present invention relates to a method for reducing vibration caused by a tire flat spot in the MDPS, wherein vibration generated by a flat spot of a tire mounted on a vehicle is reduced by using the motor driven power steering (MDPS) of the vehicle. To this end, the method for reducing vibration caused by a tire flat spot in the MDPS according to the present invention comprises: a compensation entrance determination step (S100) in which it is determined whether vibration of a tire (10), which is inputted through a steering wheel (30), is compensated; a flat spot vibration determination step (S200) in which it is determined whether the vibration is generated by the flat spot of the tire (10); and a vibration compensation step (S300) which generates inverse-phase torque to offset the vibration delivered from the tire (10).

    본 발명은 차량에 장착된 타이어의 플랫 스팟(Flat Spot)에 의해 발생하는 진동을 차량의 MDPS(Motor Driven Power Steering)를 이용하여 저감하는 MDPS에서 타이어 플랫 스팟에 의한 진동 저감 방법 진동 저감 방법에 관한 것이다. 본 발명에 따른 MDPS에서 타이어 플랫 스팟에 의한 진동 저감 방법 진동 저감 방법은, 스티어링 휠(30)을 통하여 입력된 타이어(10)의 진동을 보상할 것인지를 판단하는 보상 진입 판단 단계(S100)와, 상기 진동이 상기 타이어(10)의 플랫 스팟에 의한 것인지를 판단하는 플랫 스팟 진동 판단 단계(S200)와, 상기 타이어(10)로부터 전달되는 진동을 상쇄하기 위한 역상토크를 발생시키는 진동 보상 단계(S300)를 포함한다.
