| description | PROBLEM TO BE SOLVED: To provide a control device which has high learning accuracy of a reference position and can detect abnormality in function relevant to reference position learning.SOLUTION: A control device comprises: a current limit circuit 75 for limiting a current flowing through a winding wire 22 and MOSs 61, 62, 63 in a manner such that a current value detected by a current detection circuit 74 selectively coincides with any of a predetermined first current limit value and a predetermined second current limit value; and an MPU 80 which causes a motor 20 to rotate until a detent plate 32 stops at a limit position of a movable range while limiting a current flowing through the winding wire 22 and the MOSs 61, 62, 63 by the current limit circuit 75 to lean a reference position. The MPU 80 calculates an amount of change of a rotation angle of the detent plate 32 when changing from a first state where the current value coincides with the first current limit value to a second state where the current value coincides with the second current limit value, and determines that the current detection circuit 74 is abnormal when the amount of change is out of a predetermined range.
【課題】基準位置の学習精度が高く、基準位置学習に関する機能の異常を検出可能な制御装置を提供する。【解決手段】電流制限回路７５は、電流検出回路７４により検出される電流値が所定の第１電流制限値および第２電流制限値のどちらかに選択的に一致するよう、巻線２２およびＭＯＳ６１、６２、６３を流れる電流を制限する。ＭＰＵ８０は、電流制限回路７５により巻線２２およびＭＯＳ６１、６２、６３を流れる電流を制限しつつ、ディテントプレート３２が可動範囲の限界位置で停止するまでモータ２０を回転させ、モータ２０の基準位置を学習する。また、ＭＰＵ８０は、電流値が第１電流制限値と一致する第１状態から、電流値が第２電流制限値と一致する第２状態まで変化させたときのディテントプレート３２の回転角の変化量を算出し、この変化量が所定範囲外である場合、電流検出回路７４が異常であると判定する。【選択図】図１ |
