PROBLEM TO BE SOLVED: To provide a vehicle drive unit capable of more rapidly attenuating magnetic fluxes after notch-off, and to provide an inverter controller.SOLUTION: A vehicle drive unit includes an induction motor, an inverter and an inverter control part. The induction motor outputs driving force. The inverter drives the induction motor. The inverter control part controls the inverter. The inverter control part performs notch-off for stopping output from the induction motor in response to input signals, and controls the inverter so as to apply d-axis electric current in a direction opposite to the one before the notch-off, after the notch-off.SELECTED DRAWING: Figure 1

    【課題】より迅速にノッチオフ後の磁束を減衰させることができる車両駆動装置、およびインバータ制御装置を提供することである。【解決手段】誘導電動機と、インバータと、インバータ制御部とを持つ。誘導電動機は、駆動力を出力する。インバータは、前記誘導電動機を駆動する。インバータ制御部は、前記インバータを制御する。また、インバータ制御部は、入力信号に応じて前記誘導電動機の出力を停止させるノッチオフを行うと共に、前記ノッチオフ後において前記ノッチオフ前とは逆方向のd軸電流を流すように、前記インバータを制御する。【選択図】図1
