RECALIBRATION OF A TORQUE MEASUREMENT DEVICE WITH RECALIBRATION INTERVAL PREDICTION

WIPO Patent Application WO/2024/040459

A9

A method is provided for recalibrating an torque measurement device configured to determine a torque value of an applied torque using a calibration function derived during a calibration of the torque measurement device. The method includes performing a recalibration of the torque measurement device in which a second calibration function is derived and written to the torque measurement device(502). The method includes determining a deviation in the torque value determined using the calibration function relative to the second calibration function(504). The method includes predicting an interval from the recalibration to a next recalibration of the torque measurement device, for a different deviation over the next interval, based on the deviation, the different deviation, and the interval from the calibration to the recalibration(506). And the method includes outputting an indication of the interval from the recalibration to the next recalibration(508).
