To reduce a response delay until a large torque corresponding to a sudden acceleration request is generated when the sudden acceleration request is made.SOLUTION: The rotation speed of first and second electric motors at a given vehicle speed is set to a rotation speed in a range in which an upper limit value TM1_u of the torque of a first electric motor and an upper limit value TM2_u of the torque of a second electric motor at that speed are the maximum values. When there is a sudden acceleration request, the output torque of the driving device can be set to the maximum value at that speed without changing the rotation speed of the first and second electric motors.SELECTED DRAWING: Figure 3

    【課題】急な加速要求があったとき、これに見合う大トルクの発生までの応答遅れを小さくする。【解決手段】ある車両速度における第1および第2電動機の回転速度を、その速度における第1電動機のトルクの上限値TM1_uおよび第2電動機のトルクの上限値TM2_uが最大値となる範囲の回転速度に設定する。急な加速要求があったとき、第1および第2電動機の回転速度を変更せずに、駆動装置の出力トルクを、その速度における最大値とすることができる。【選択図】図3
