To provide a control device of a rotary electrical machine capable of properly detecting an occurrence of abnormality in the control device while restraining the occurrence of a situation where abnormal time processing is performed in spite of being not in a state where abnormal time processing should be performed.SOLUTION: A control device 100 includes a vehicle control unit 50 and a monitoring unit 70. The vehicle control unit 50 calculates a target torque Tac of a rotary electrical machine 20 based on an accelerator pressing amount Acc, a vehicle speed Vs and a shift position SP, and a travel mode signal Mo. The monitoring unit 70 calculates a target monitoring torque based on the Acc, the Vs, and the Sp. The monitoring unit 70 does not calculate a deviation between the target torque Tac and the target monitoring torque when the target torque Tac is less than a first judgement value while the vehicle 10 is advancing forward. The monitoring unit 70 does not calculate the deviation between the target torque Tac and the target monitoring torque when the target torque Tac exceeds a second judgement value while the vehicle 10 is advancing backward.SELECTED DRAWING: Figure 1

    【課題】異常時処理を実行すべき状況でないにもかかわらず異常時処理が実行されてしまう事態の発生を抑制しつつ、制御装置内の異常の発生を適正に検知できる回転電機の制御装置を提供する。【解決手段】制御装置100は、車両制御部50及び監視部70を備えている。車両制御部50は、アクセル操作量Acc、車速Vs及びシフトポジションSPと、走行モード信号Moとに基づいて、回転電機20の目標トルクTacを算出する。監視部70は、上記Acc,Vs,SPに基づいて、目標監視トルクを算出する。監視部70は、車両10の前進時において、目標トルクTacが第1判定値を下回る場合、目標トルクTacと目標監視トルクとの偏差を算出しない。監視部70は、車両10の後進時において、目標トルクTacが第2判定値を上回る場合、目標トルクTacと目標監視トルクとの偏差を算出しない。【選択図】 図1
