Abstract
A sensor equipped wheel support bearing assembly, in which a continuous estimated load can be obtained depending on various inputted load conditions is provided. The sensor equipped wheel support bearing assembly includes a sensor unit provided in a stationary member, and a load estimating unit. The load estimating unit includes a load estimation calculating section for calculating the load using an estimation calculating equation, an evaluation value calculation section for calculating an evaluation value, which provides a parameter switching index in the estimation calculating equation, from sensor output signals, and a parameter switching section for switching the parameter based on a comparison result of the evaluation value with a threshold value. The load estimation calculating section includes a calculation correcting block for correcting the calculation result on both sides of the threshold value within a predetermined evaluation value region containing the threshold value.
