Abstract
Provided is a sensor-equipped wheel support bearing assembly for rotatably supporting a wheel, including a sensor unit associated with one of outer and inner members that serve as a stationary member. The sensor unit includes a strain generator member that has at least three fixation contact segments fixedly in contact with the stationary member and at least two strain sensors mounted on the strain generator member. A first load estimator is provided to estimate load acting on the bearing assembly, using an average value of output signals of the sensors. A second load estimator is provided to estimate load acting on the bearing assembly, using the average value and an amplitude value of output signals of the sensors. An estimated load provider is provided to sum these outputs from the load estimators in a ratio that depends on wheel rotation speed, for outputting an estimated load.
