The present invention relates to a diagnosis apparatus and a diagnosis method of a wheel bearing, and the wheel bearing having the same. According to one embodiment of the present invention, provided is the diagnosis apparatus for diagnosing whether a wheel bearing is malfunctioning or operating abnormally. The diagnosis apparatus of the wheel bearing according to one embodiment of the present invention may comprise: a sensing unit detecting information related to an operating state of a vehicle; and a diagnosis unit diagnosing the wheel bearing based on operation state information of the vehicle detected by the sensing unit. According to one embodiment of the present invention, the sensing unit includes an acceleration sensor for detecting acceleration information. In addition, the acceleration sensor may be configured to detect acceleration along equal to or more than two axes, including the acceleration along the axle direction and the acceleration along the vertical direction of the vehicle. The diagnosis unit may be configured to diagnose the wheel bearing in a state where the acceleration along the axle direction detected by the acceleration sensor is located within a range of ±0.3 G. An objective of the present invention is to provide the diagnosis apparatus and the diagnosis method of the wheel bearing and the wheel bearing having the same, configured to perform a more stable and reliable diagnosis.
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.
