Abstract:
An angle sensor includes detection units and an angle computation unit. The detection units detect a composite magnetic field of a magnetic field to be detected and a noise magnetic field. Each detection unit generates a first detection signal representing the strength of a component in a first direction of the composite magnetic field, and a second detection signal representing the strength of a component in a second direction of the composite magnetic field. The angle computation unit generates a detected angle value by performing computations using a plurality of pairs of first and second detection signals generated at the detection units wherein an error of the detected angle value resulting from the noise magnetic field is made smaller than in the case of generating the detected angle value on the basis of only a pair of first and second detection signals generated at any one of the detection units.

Claim (Index 6):
The angle sensor according to  claim 5 , wherein\n the angle computation unit assumes first unknown magnetic field information, second unknown magnetic field information, a plurality of first assumed detection values, a plurality of second assumed detection values, a plurality of first residuals, and a plurality of second residuals, the first unknown magnetic field information corresponds to strengths, at a predetermined position, of a component in the first direction and a component in the second direction of the magnetic field to be detected, the second unknown magnetic field information corresponds to strengths of a component in the first direction and a component in the second direction of the noise magnetic field, each of the plurality of first assumed detection values is a value that corresponds to one of the first detection signals generated at the plurality of detection units and is assumed on the basis of the first and second unknown magnetic field information, each of the plurality of second assumed detection values is a value that corresponds to one of the second detection signals generated at the plurality of detection units and is assumed on the basis of the first and second unknown magnetic field information, each of the plurality of first residuals is a difference between one of the first detection signals generated at the plurality of detection units and a corresponding one of the first assumed detection values, each of the plurality of second residuals is a difference between one of the second detection signals generated at the plurality of detection units and a corresponding one of the second assumed detection values, and the angle computation unit estimates the first and second unknown magnetic field information so as to minimize the sum of squares of the plurality of first residuals and to minimize the sum of squares of the plurality of second residuals, and determines the detected angle value on the basis of the estimated first unknown magnetic field information.
