Zusammenfassung:To provide a vehicular control device that can suppress decrease in output torque by a driving motor involved in completion of temporary power-up.SOLUTION: Output (generated electric power) of a power generation motor at the time of completing temporary power-up is predicted during the temporary power-up. A limit value of the output of the driving motor during the temporary power-up is set so that output (MG2 consumption power) of the driving motor at the time of completing the temporary power-up is not more than an additional value of the predicted value of the output of the power generation motor and electric power (output of a battery for MG2) determined by subtracting output other than output to the driving motor from rated power of a battery 11. During the temporary power-up, when the MG2 consumption power reaches the limit value, the MG2 consumption power is limited to the limit value until a limited time set in accordance with the limit value and an increase rate of the MG2 consumption power elapses thereafter.SELECTED DRAWING: Figure 2 【課題】一時アップの終了に伴う駆動モータの出力トルクの低下を抑制できる、車両用制御装置を提供する。【解決手段】一時アップ中に、一時アップの終了時点における発電モータの出力(発電電力)が予測される。そして、一時アップの終了時点での駆動モータの出力(MG2使用電力)が発電モータの出力の予測値と電池11の定格電力から駆動モータ以外への出力分を差し引いた電力(MG2用電池出力)との加算値以下となるように、一時アップ中における駆動モータの出力の制限値が設定される。一時アップ中に、MG2使用電力が制限値に達すると、その時点から制限値とMG2使用電力の上昇率に応じて設定される制限時間が経過するまで、MG2使用電力が制限値に制限される。【選択図】図2
