The invention relates to a sensor system (1), and a method for determining an absolute rotation angle (δ) of a shaft (10) with a rotation angle range of more than one revolution and to a vehicle fitted with a sensor system (1), wherein the sensor system (1) has a main rotor (2) that can be connected rotationally synchronously to the shaft (10), a first auxiliary rotor (3) which is mechanically coupled to the main rotor (2), a second auxiliary rotor (4) mechanically coupled to the main rotor (2), a first sensor device (SE1) which is assigned to the first auxiliary rotor (3) for generating a first sensor signal dependent on a rotation angle of the first auxiliary rotor (3), a second sensor device (SE2) which is assigned to the second auxiliary rotor (4) for generating a second sensor signal dependent on a rotation angle of the second auxiliary rotor (4), a third sensor device (SE3) which is assigned to the main rotor (2) and which is used for generating a third sensor signal dependent on a relative rotation angle (γ) of the main rotor (2) and an evaluation device for determining the absolute rotation angle (δ) of the main rotor (2) from the sensor signals of the sensor devices (SE1, SE2, SE3). The detection range (α) of the third sensor device is less than 360°.
