According to an embodiment of the present invention, a diagnostic device for diagnosing whether a wheel bearing is broken or abnormally operated is provided. A diagnostic device for a wheel bearing according to an embodiment of the present invention comprises: a sensing unit for detecting information related to the operating state of a vehicle; and a diagnostic unit for diagnosing a wheel bearing based on the vehicle's operating state information detected by the sensing unit. According to an embodiment of the present invention, the sensing unit includes an acceleration sensor for detecting acceleration information. The acceleration sensor can be configured to detect acceleration in two or more axes, including acceleration in an axle axis and acceleration in an up-down direction of a vehicle. The diagnostic unit can be configured to diagnose the wheel bearing in a state in which the acceleration in an axle direction detected by the acceleration sensor is located within a range of ±0.3 G. The present invention can stably and reliably perform fault diagnosis on the wheel bearing.

    본 발명의 일 실시예에 따르면, 휠베어링의 고장 또는 이상 작동 여부를 진단하는 진단장치가 제공된다. 본 발명의 일 실시예에 따른 휠베어링의 진단장치는 차량의 작동 상태와 관련된 정보를 검출하는 센싱부와, 센싱부에서 검출된 차량의 작동 상태 정보를 기초로 휠베어링을 진단하는 진단부를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 센싱부는 가속도 정보를 검출하는 가속도 센서를 포함하고, 가속도 센서는 차축방향을 따르는 가속도 및 차량의 상하방향을 따르는 가속도를 포함해 2축 이상의 가속도를 검출하도록 구성될 수 있으며, 진단부는 가속도 센서에 의해 검출된 차축방향을 따르는 가속도가 ±0.3G 이내의 범위에 위치하는 상태에서 휠베어링을 진단하도록 구성될 수 있다.
