摘要

The method involves detecting offset errors that concern a torque sensor, and combining the offset errors to a total offset error (20), which represents an offset error to be determined of the sensor. The total offset error is provided as a mean value or median value of the detected offset errors or a sub-group of the detected offset errors by an extrapolation of the offset errors, where the sub-group is formed from a predetermined number of last detected offset errors. The extrapolation is compensated based on offset error drift (40) or a detected operating parameter such as temperature. An independent claim is also included for a device for determining an offset error of a torque sensor of a bicycle pedal drive.
