PROBLEM TO BE SOLVED: To effectively reduce vibration when a power train mounted on an electric automobile inclines to a front side or a rear side related to a reference position.SOLUTION: A motor control device 20 of an electric automobile 1 including a power train 10 having a motor 11 includes: an inclination determination part 21 for determining that when inclination in a cross direction of the power train 10 is changed to a front side or a rear side related to a reference position which is a position of the power train 10 in a vehicle stop state, the inclination is changed; and a torque control part 22 for increasing and decreasing torque of the motor 11 at more gradual torque increase and decrease rate than that after it is determined that the inclination is changed until it is determined by the inclination determination part 21 that the inclination is changed.

    【課題】電気自動車に搭載されたパワートレーンが基準位置に対して前後に傾くときの振動を効果的に低減する。【解決手段】モータ11を有するパワートレーン10を備えた電気自動車1のモータ制御装置20において、パワートレーン10の前後方向の傾きが、車両停止状態でのパワートレーン10の位置である基準位置に対して、前方側へ、あるいは後方側へと切り替わるとき、傾きが切り替わったことを判定する傾き判定部21と、傾き判定部21により傾きが切り替わったと判定されるまでは、傾きが切り替わったと判定された後よりも緩やかなトルク増減レートで、モータ11のトルクを増減させるトルク制御部22と、を設ける。【選択図】図1
