Abstract
A method for determining an angle of rotation between a sensor array and a magnetic field of a magnet, whereby the magnetic field is formed substantially parallel and perpendicular to the rotation axis, and the magnet is arranged rotationally symmetric relative to the rotation axis. A first measurement signal and a second measurement signal are generated by the two subsensors of the first magnetic field sensor unit, and the first measurement signal is assigned a first relation and the second measurement signal is assigned a second relation. A third measurement signal and a fourth measurement signal are generated by the two subsensors of the second magnetic field sensor unit, whereby the third measurement signal is assigned a third relation and the fourth measurement signal is assigned a fourth relation. The angle of rotation is then determined.
