PROBLEM TO BE SOLVED: To provide a motor drive unit which can prevent that a driver feels incongruity when the driver of a vehicle which is mounted with the motor drive unit operates accelerator operation means.SOLUTION: This motor drive unit has an electric motor 5, a control device 6 and vehicle speed detection means 7. The control device 6 has an ECU 8 and a torque control part 11. Vehicle-speed correspondence torque control means 10 is interposed between the ECU 8 and the torque control part 11. The vehicle-speed correspondence torque control means 10 has an accelerator sensitivity adjustment part which adjusts a torque command value imparted to the torque control part 11 according to an operation amount so that current vehicle-speed correspondence maximum torque which is uniquely defined from vehicle-speed correspondence maximum torque which is changed by a vehicle speed reaches a maximum value of the torque command value which is imparted to the torque control part 11 from the vehicle-speed correspondence means 10 at a maximum operation amount of accelerator operation means 12, and that the torque command value is proportioned to the operation amount of the accelerator operation means 12.SELECTED DRAWING: Figure 2

    【課題】 このモータ駆動装置を搭載した車両の運転者がアクセル操作手段を操作するとき、運転者に違和感を与えることを防止することができるモータ駆動装置を提供する。【解決手段】 このモータ駆動装置は、電動モータ5と制御装置6と車速検出手段7とを有する。制御装置6は、ECU8とトルク制御部11とを有する。ECU8とトルク制御部11との間に車速対応トルク制御手段10を介在させる。車速対応トルク制御手段10は、車速によって変化する車速対応最大トルクから一意に定まる現在の車速対応最大トルクが、アクセル操作手段12の最大操作量で車速対応トルク制御手段10からトルク制御部11に与えられるトルク指令値の最大値となり、かつアクセル操作手段12の操作量にトルク指令値が比例するように、操作量に応じてトルク制御部11に与えられるトルク指令値を調整するアクセル感度調整部を有する。【選択図】 図2
