To prevent that an accumulation device reaches overdischarging.SOLUTION: When a requirement drive force is equal to a first upper limit drive force or smaller, a control device sets the requirement drive force as a target drive force. On the other hand, when the requirement drive force is larger than the first upper limit drive force, the control device sets the target compensation power of an accumulation device on the basis of a difference between the requirement drive force and the first upper limit drive force, outputs upper limit power from an engine, sets the second upper limit power of a drive shaft when the accumulation device performs an accumulator-power compensation for performing charging and discharging by power based on the target compensation power, and sets a smaller one out of the requirement drive force and the second upper limit drive force as the target drive force. Also, the control device employs a type-1 gear change line as a gear change line for changing a gear change stage, and when a prescribed condition including a condition that an accumulation ratio of the accumulation device is a first ratio or lower is established, the control device changes the gear change line to a type-2 gear change line for recommending a low-speed stage lower than that of the type-1 gear change line.SELECTED DRAWING: Figure 15

    【課題】蓄電装置が過放電に至るのを抑制する。【解決手段】制御装置は、要求駆動力が第1上限駆動力以下のときには、要求駆動力を目標駆動力として設定する。一方、制御装置は、要求駆動力が第1上限駆動力よりも大きいときには、要求駆動力と第1上限駆動力との差分に基づいて蓄電装置の目標補填パワーを設定し、エンジンから上限パワーを出力すると共に蓄電装置が目標補填パワーに基づくパワーで充放電する蓄電装置パワー補填を行なうときの駆動軸の第2上限駆動力を設定し、要求駆動力および第2上限駆動力のうちの小さい方を目標駆動力として設定する。更に、制御装置は、変速段を変更するための変速線として第1種変速線が用いられていて、且つ、蓄電装置の蓄電割合が第1割合以下である条件を含む所定条件が成立すると、変速線を第1種変速線よりも低速段を推奨する第2種変速線に変更する。【選択図】図15
