PROBLEM TO BE SOLVED: To provide a motor controller capable of compensating influence of hysteresis and torque ripple, and smoothing a conductive state of an electric motor.SOLUTION: A motor controller of a vehicle comprises: operation amount acquisition means BPA of acquiring a control operation amount Bpa; an electric motor that allows a rotation member fixed to a wheel of the vehicle to occur a brake torque of the wheel by pressing a friction member; a controller CTL that calculates a target conductive amount Imt on the basis of the control operation amount Bpa of an operation member BP of the vehicle, and adjusts an output of the electric motor on the basis of the target conductive amount Imt; and rotation angle detection means MKA of acquiring a rotation angel Mka of the electric motor. The controller CTL determines whether or not a non-change state where the control operation amount Bpa is changed, and the rotation angel Mka is not changed on the basis of the control operation amount Bpa and the rotation angel Mka. When determined to be in the non-change state, a preset pulse waveform compensation amount Itr is overlapped to the target conductive amount Imt.SELECTED DRAWING: Figure 3

    【課題】ヒステリシス、トルクリップルの影響を補償し、且つ、電気モータの通電状態を円滑化し得るものを提供する。【解決手段】車両のモータ制御装置は、制動操作量Bpaを取得する操作量取得手段BPAと、車両の車輪に固定された回転部材に摩擦部材を押圧し車輪の制動トルクを発生させる電気モータと、車両の操作部材BPの操作量Bpaに基づいて目標通電量Imtを演算し、目標通電量Imtに基づいて電気モータの出力を調整するコントローラCTLと、さらには、電気モータの回転角Mkaを取得する回転角検出手段MKAと、を備える。コントローラCTLは、操作量Bpa、及び、回転角Mkaに基づいて、操作量Bpaが変化し、且つ、回転角Mkaが変化しない無変化状態であるか、否か、を判定し、無変化状態であることが判定された場合に、予め設定されたパルス波形状の補償通電量Itrを目標通電量Imtに重畳する。【選択図】図3
