Abstract
A method for operating a sensor system of an electric bicycle is disclosed. The sensor system includes a torque sensor formed as a magnetoelastic sensor and configured to ascertain a torque on a shaft based on a detection of changes of a magnetic field. The method includes (i) detecting a homogeneous magnetic flux density by way of the torque sensor, (ii) ascertaining a torque on the shaft by way of the torque sensor, and (iii) detecting a torque error of the ascertained torque when the detected homogeneous magnetic flux density is greater than or equal to a predetermined first threshold value.
