Zusammenfassung:	To perform a smooth power-on downshift in a hybrid vehicle having a stepped automatic transmission.SOLUTION: When a maximum step number of a power-on downshift which is assumed from a current vehicle speed V and a gear stage of an automatic transmission is large, reserve torque TRRV is calculated with a value which becomes larger than that in the case that the maximum step number is small. (S110). Then, a difference which is obtained by subtracting the reserve torque TRRV from the maximum torque TRMAX of a M/G is set as an upper limit value of traveling assist torque TR (S130).SELECTED DRAWING: Figure 4 【課題】有段式の自動変速機を備えるハイブリッド車両での円滑なパワーオンダウンシフトを実現する。【解決手段】現在の車速Ｖ及び自動変速機のギア段から想定されるパワーオンダウンシフトの最大ステップ数が大きいときには、同最大ステップ数が小さいときよりも大きい値となる値としてリザーブトルクＴＲＲＶを演算する（Ｓ１１０）。そして、Ｍ／Ｇの最大トルクＴＲＭＡＸからリザーブトルクＴＲＲＶを引いた差を走行アシストトルクＴＲの上限値として設定するようにした（Ｓ１３０）。【選択図】図４
