Abstract
An angle sensor temperature correcting device includes: a zero correcting factor storing portion that stores, as a reference temperature bridge midpoint potential difference offset and a bridge total resistance indicating value, a difference from an actual correct value, for a relative angle between a bridge circuit and a magnetic field, for the bridge midpoint potential difference, and a value indicating the total resistance of the bridge circuit, at a reference temperature, and stores, as a zero correcting factor, a ratio of the bridge midpoint potential difference offset and the bridge total resistance indicating value at the reference temperature; and a temperature correcting portion that performs temperature correction on angle information obtained from the bridge midpoint potential difference of the bridge circuit at a given time, based on a zero correcting factor stored in the zero correcting factor storing portion.
