Abstract
An angle sensor includes a detection signal generation unit for generating detection signals, an angle detection unit for generating a detected angle value on the basis of the detection signals, and a condition determination apparatus. The condition determination apparatus includes a determination value generation unit for generating a determination value to be used for determining the condition of the angle sensor, and a determination unit for determining the condition of the angle sensor. The angle detection unit includes a common correction processing unit for performing common correction processing for converting uncorrected signals, which have correspondence with the detection signals, into common corrected signals to be used for the generation of the detected angle value and the generation of the determination value. The common correction processing reduces an angular error occurring in the detected angle value, and narrows the variation range of the determination value.
