Title:
WHEEL BEARING DEVICE WITH ATTACHED SENSOR
Document Type and Number:
WIPO Patent Application WO/2014/087871
Kind Code:
A1
Abstract:
Provided is a wheel bearing device with an attached sensor that is capable of estimating accurate load values, independent of the frequency of vibrations produced by the input load. A wheel bearing (100) is provided with a plurality of sensors (20) for detecting loads applied to the wheel bearing. The following are provided: a signal processing means (31) for generating signal vectors from the output signals of the sensors; a load computation processing means (32) for computing loads applied to the wheel from the signal vectors, and an input load vibration detection means (33) for detecting fluctuating components of the input loads included in the output signals of the sensors (20). The load computation processing means (32) computes loads by switching between load computation processing methods in accordance with the fluctuating components detected by the input load vibration detection means (33).
