PROBLEM TO BE SOLVED: To provide a motor torque control device capable of operating a regenerative brake even in low speed time, by adjusting a size of creep torque in a low speed area, in response to a will of a driver.SOLUTION: An electric vehicle for generating a creep torque by operating motor torque as a value of a plus when an accelerator is turned off and a speed of the vehicle is a low speed area less than a predetermined value, by generating low speed regenerative torque by operating the motor torque of a driving motor 21 as a value of a minus when the accelerator is turned off, comprises a motor torque setting part 11 capable of optionally setting a size of the motor torque by operation of a driver when the accelerator is turned off and the speed is the low speed area and a torque control part 19 for controlling the size of the motor torque in response to a setting state of the motor torque setting part 11, and the motor torque setting part 11 constitutes a motor torque control device capable of setting the size of the motor torque up to the value of the minus from the plus.SELECTED DRAWING: Figure 1

    【課題】ドライバの意思に対応して、低速領域におけるクリープトルクの大きさを調整可能とし、低速時にも回生ブレーキを働かせることを可能としたモータトルク制御装置を提供する。【解決手段】アクセルオフのときに駆動用モータ21のモータトルクをマイナスの値に働かせることで低速回生トルクを発生させ、アクセルオフかつ車両の速度が所定値以下の低速領域のときに前記モータトルクをプラスの値に働かせることでクリープトルクを発生させる電動車両であって、アクセルオフかつ前記速度が前記低速領域であるときの前記モータトルクの大きさを、ドライバの操作により任意に設定可能なモータトルク設定部11と、モータトルク設定部11の設定状態に対応して、前記モータトルクの大きさを制御するトルク制御部19と、を有し、モータトルク設定部11は、前記モータトルクの大きさをプラスからマイナスの値まで設定できるモータトルク制御装置を構成する。【選択図】図1
