20100114524 | ROTATION ANGLE DETECTION APPARATUS - A rotation angle detection apparatus has angle detection means that has detection circuits each including a detection element part having a coil and a resistor and that also has inductance changing means that changes the inductance of the coil in accordance with the rotation of a rotation measurement target. The rotation angle detection apparatus further has reference pulse voltage generating means for causing the detection circuits to generate output signals; and calculating means for calculating the output signals of the detection circuits. The calculating means obtains an integral by integrating, for a predetermined time, a transient output voltage occurring when a reference pulse voltage generated by the reference pulse voltage generating means is input to the detection circuits. The calculating means then detects, based on the integral, a rotation angle of the rotation measurement target, whereby the number of components of the rotation angle detection apparatus can be reduced and error factors of the output signal of the detection circuits can be reduced. As a result, the logic circuits and amplifier circuits can be simplified and hence the cost of the rotation angle detection apparatus can be reduced. | 05-06-2010 |
