Abstract
A magnetic-field-based angle sensor system includes a stator component and a rotor component rotatable relative thereto, a magnetic field sensor operating in saturation operation and a magnetic field sensor operating in linear operation, wherein the magnetic field sensor operating in saturation operation is configured to determine a rotation angle of the rotor component relative to the stator component, and wherein the magnetic field sensor operating in linear operation is configured to ascertain an external magnetic stray field acting on the angle sensor system. The angle sensor system further includes a control device configured, based on the ascertained external magnetic stray field, to compensate for a stray-field-dependent measurement deviation in the determination of the rotation angle carried out.
