Abstract
Rotation angle computation modes include a normal mode and a simple mode. In normal mode, a rotation angle of an input shaft is computed based on output signals from first and second magnetic sensors, which are sampled at two sampling timings. In simple mode, the rotation angle of the input shaft is computed based on the output signals from the first and second magnetic sensors, which are sampled at one sampling timing, and an amplitude ratio between the output signals from the magnetic sensors set in advance. After a power supply is turned on, the rotation angle is computed in the simple mode until a condition that the rotation angle of the input shaft can be computed in the normal mode even if the immediately preceding value of the rotation angle of the input shaft is not present is satisfied. Then, the rotation angle is computed in the normal mode.
