PROBLEM TO BE SOLVED: To provide a control device which is hardly influenced by a variation of an output voltage of a sensor, and easy in the detection of an abnormal sensor, in the control device 20 of a shift position detection device 60 composed of at least four pieces sensors 64, 64, 66 and 68.SOLUTION: In all shift positions Psh, a detection value D for discriminating an output voltage of a sensor group P1 composed of two pieces of sensors, and an output voltage of a sensor group P2 composed of remaining two pieces sensors is set, it is determined that an abnormality exists when the output voltage of the sensor in the same group has an output voltage which is divided into a high output voltage and a low output voltage with respect to the determination value D, and then, the sensor having the output voltage at the same side as that of the remaining group with respect to the determination value D is specified as abnormal, thus detecting an abnormal sensor.SELECTED DRAWING: Figure 8
【課題】少なくとも4個のセンサ64、64、66、68からなるシフト位置検出装置60の制御装置20において、センサの出力電圧のばらつきの影響を受けにくく、異常なセンサの検出が容易な制御装置を提供する。【解決手段】全てのシフト位置Pshにおいて、2個のセンサからなるセンサ組P1の出力電圧と残りの2個のセンサからなるセンサ組P2の出力電圧とを判別する判定値Dを設定し、同じ組のセンサの出力電圧が判定値Dに対して大小に分かれた出力電圧を持つ場合に異常があると判定し、判定値Dに対し残りの組と同じ側の出力電圧を持つセンサを異常と特定することで異常なセンサを検出する。【選択図】図8
