PROBLEM TO BE SOLVED: To suppress the occurrence of an occasion that the drive of a motor is limited.SOLUTION: In the case S110 that a motor is regeneratively driven, and an electric system temperature is not lower than a prescribed temperature, a change amount of a gear change ratio to a downshift side is set on the basis of the electric system temperature and motor regeneration torque S140, and a target gear change ratio is set so that the gear change ratio is changed to the downshift side from a current gear change ratio by the change amount S150. By this constitution, a rise of the electric system temperature can be further properly suppressed by reducing a current flowing in an inverter. As a result, the occurrence of a limit of the drive of the motor can be suppressed.SELECTED DRAWING: Figure 2

    【課題】モータの駆動が制限される機会の発生を抑制する。【解決手段】モータを回生駆動しており、且つ、電気系温度が所定温度以上であるときS110には、電気系温度とモータ回生トルクとに基づいて変速比のダウンシフト側への変更量を設定S140し、変速比が現在の変速比からダウンシフト側へ変更量だけ変化するように目標変速比を設定S150する。これにより、より適正に、インバータに流れる電流を小さくして、電気系温度の上昇を抑制することができる。この結果、モータの駆動の制限の発生を抑制することができる。【選択図】図2
