  • Publication number: 20210278315
    Abstract: There is provided a method for diagnosing the presence of failure or abnormal operation of a wheel bearing. The method includes detecting acceleration information by an acceleration sensor mounted to a rotational central axis of the wheel bearing or at a position radially spaced apart from the rotational central axis and configured to rotate together with the wheel bearing; calculating speed information based on the acceleration information detected by the acceleration sensor; and diagnosing the wheel bearing based on the acceleration information detected by the acceleration sensor and the speed information calculated from the acceleration information. In the acceleration detection step, the acceleration sensor collects the acceleration information in at least one of a first direction extending radially from the rotational central axis of the wheel bearing and a second direction perpendicular to the first direction on a plane perpendicular to the rotational central axis of the wheel bearing.
