본 발명은 인휠 구동 시스템의 고장 검출 장치 및 방법에 관한 것으로, 인휠 모터, 인휠 모터에 기어로 접속되어 모터의 회전력을 휠에 전달하는 적어도 하나 이상의 감속부, 인휠 모터 및 상기 감속부의 회전수를 각기 감지하는 센서부, 및 상기 센서부를 통해 감지한 각 회전수를 이용해 상기 인휠 모터와 감속부 간의 회전수 비를 산출하고, 상기 산출한 회전수 비에 기초하여 상기 감속부의 손상이나 고장 여부를 판단하는 제어부를 포함한다.
An apparatus for detecting a fault in an in-wheel driving system of a vehicle including: an in-wheel motor; at least one speed reduction part coupled to the in-wheel motor through a gear and transferring a rotation force of the in-wheel motor to a wheel; a sensor part sensing rpms of the in-wheel motor and the speed reduction part; and a control unit suitable for calculating an rpm ratio between the in-wheel motor and the speed reduction part by using the respective rpms sensed through the sensor parts and determining whether a damage or a fault has occurred in the speed reduction part, based on the calculated rpm ratio.
