Abstract
A method for estimating a bearing load in a bearing having a first ring, a second ring and a row of rolling elements arranged between the first ring and the second ring, the method including: equipping the first ring with at least one strain sensor probe, transmitting a strain signal waveform from the at least one strain sensor probe to an electronic control unit, extracting shape information of the waveform of the strain signal using a first harmonic component (u) and a second harmonic component (v) of the strain signal, and calculating a bearing load estimation as a polynomial function of the first and second harmonic components (u, v) of the strain signal.
