ABSTRACT:
First and second targets, the numbers of which are coprime, are provided at a rotor. Two detecting means oppose each of the first and second targets to output detection signals having phases different from each other in accordance with each position of the targets as the rotor rotates. The rotational angle detecting apparatus has calculating means for executing a predetermined calculation based on each detection signal of the two detecting means and storage means for storing a relation between a result of calculation executed in advance by the calculating means and an electrical angle of a detection signal, obtains an electrical angle of each detection signal by referring to the storage means using a calculation result of the calculating means and detects a rotational angle of the rotor based on the obtained electrical angle. Consequently, no discontinuous portion forms in a detected steering angle signal and the differential signal thereof.
