To provide a rotary electric machine control device capable of reducing a calculation load.SOLUTION: An ECU 10 controls the drive of a motor 80 that outputs at least a part of a torque required to steer a vehicle, and includes control units 150 and 250. The control units 150 and 250 can switch a control mode between an ADS mode for controlling the drive of the motor 80 on the basis of an angle command value and an EPS mode for controlling the drive of the motor 80 on the basis of a basic assist command value which is a torque command value. The control units 150 and 250 make the calculation cycle different according to the selected control mode for at least a part of the calculation related to the drive control of the motor 80. As a result, an appropriate calculation cycle can be set for each calculation related to the drive control of the motor 80 according to the control mode, and a calculation load can be reduced.SELECTED DRAWING: Figure 5

    【課題】演算負荷を低減可能な回転電機制御装置を提供する。【解決手段】ECU10は、車両の操舵に要するトルクの少なくとも一部を出力するモータ80の駆動を制御するものであって、制御部150、250を備える。制御部150、250は、角度指令値に基づいてモータ80の駆動を制御するADSモード、および、トルク指令値である基本アシスト指令値に基づいてモータ80の駆動を制御するEPSモードを含む制御モードを切替可能である。制御部150、250は、モータ80の駆動制御に係る演算の少なくとも一部について、選択された制御モードに応じて演算周期を異ならせる。これにより、制御モードに応じ、モータ80の駆動制御に係る演算ごとに適切な演算周期とすることができ、演算負荷を低減することができる。【選択図】 図5
