Absolute measurement steering angle sensor arrangement

An angle sensor arrangement for measuring the rotational angle of a shaft having a defined rotational angle measuring range comprising:

• a first gearwheel and a first magnetic encoder with at least one encoder track and having one or more pole pairs, wherein the first gearwheel and the first magnetic encoder rotate with the shaft, and
• a second gearwheel and a second magnetic encoder with at least one encoder track and having one or more pole pairs, wherein the second encoder rotates with the second gearwheel, and the first and second gearwheels interact, and wherein at least one magnetic field sensor element is assigned to the first encoder and to the second encoder, respectively, wherein the first and second gearwheels are embodied in terms of a common transmission ratio and the first and second magnetic encoders are embodied in terms of their pole numbers in such a way that a first magnetic field sensor element which is assigned to the first or second encoder detects n poles or pole pairs over the entire rotational angle measuring range of the angle sensor arrangement, and a second magnetic field sensor element which is assigned to the other encoder detects n−1+Δ poles or pole pairs over the entire rotational angle measuring range of the angle sensor arrangement, where A is defined as a real number between 0 and 1, and n is defined as a natural number.
