  • Patent number: 10533878
    Abstract: An angle sensor includes a plurality of composite magnetic field information generation units and an angle computing unit. The plurality of composite magnetic field information generation units detect, at a plurality of detection positions, a composite magnetic field of a magnetic field to be detected and a noise magnetic field other than the magnetic field to be detected, and thereby generate a plurality of pieces of composite magnetic field information including information on the direction of the composite magnetic field. The angle computing unit generates a detected angle value by performing an operation using the plurality of pieces of composite magnetic field information so that an error of the detected angle value caused by the noise magnetic field is made smaller than in the case where the detected angle value is generated on the basis of any and only one of the plurality of pieces of composite magnetic field information.
