To provide an electrically-driven vehicle driving device which can reflect a drive force of a motor on a drive force for traveling backward more reliably.SOLUTION: An electrically-driven vehicle driving device includes: a first motor; a second motor; a transmission mechanism connected to the first motor and the second motor; and a control part controlling operation of the first motor and the second motor. The transmission mechanism is provided with: a first planetary gear mechanism; a second planetary gear mechanism; a one-way clutch restricting a rotation direction of a first carrier which the first planetary gear mechanism has to a prescribed normal rotation direction; and a detection part detecting rotary speed of the first motor. The control part controls the first motor on the basis of either rotary speed or torque when rotating the first motor in the reverse rotation direction to the prescribed normal rotation direction and rotating the second motor in the normal rotation direction and determines rotary speed of the second motor within the range shown by the equation (1) in accordance with rotary speed of the first motor.SELECTED DRAWING: Figure 17

    【課題】モータの駆動力を後進のための駆動力により確実に反映可能な電動車両駆動装置を提供すること。【解決手段】電動車両駆動装置は、第1モータと、第2モータと、第1モータ及び第2モータに連結される変速機構と、第1モータ及び第2モータの動作を制御する制御部と、を備え、変速機構は、第1遊星歯車機構と、第2遊星歯車機構と、第1遊星歯車機構が有する第1キャリアの回転方向を所定の正回転方向に制限するワンウェイクラッチと、第1モータの回転速度を検出する検出部を備える。制御部は、第1モータを所定の正回転方向とは逆回転方向に回転させ且つ第2モータを正回転方向に回転させる場合、第1モータの制御を回転速度又はトルクのいずれかに基づいて行い、第1モータの回転速度に応じて、式(1)が示す範囲内で第2モータの回転速度を決定する。【選択図】図17
