Abstract
A method of correcting temperature characteristic of a rotation angle detecting device that includes a permanent magnet, a magnetic core, a Hall element that rotates relative to the permanent magnet when a rotating object rotates to provide an output signal. The method includes a step of setting temperature correction values for correcting a temperature characteristic of the rotation angle detecting device according to magnetic flux density. The magnetic flux density is divided into a plurality of grade ranges and the temperature correction values are respectively set for the grade ranges.
