To prevent rotational elements engaged with each other from causing abnormal gear rattle and damage when a neutral range of an automatic transmission is released during a changeover of gear stages of an auxiliary transmission.SOLUTION: A vehicle power transmission device performs: a changeover of gear stages of an auxiliary transmission 20 with a clutch sleeve moved from either one of a high gear position or a low gear position to the other under the condition that an automatic transmission 13 is in a neutral range and a vehicle C is stopped; torque limit control which limits torque of an engine 10 in a case where the clutch sleeve positioned, at the start of being moved, in a torque limit execution range including the low gear position; and return control which returns the gear stage of the auxiliary transmission 20 to the gear stage before the changeover thereof in a case where the clutch sleeve is positioned in the torque limit execution range when the neutral range of the automatic transmission 13 is released during the changeover of the gear stages of the auxiliary transmission 20.SELECTED DRAWING: Figure 1

    【課題】副変速機のギア段の切替中に自動変速機のニュートラルレンジが解除された場合の係合する回転要素の歯打ちによる異音や損傷を抑える。【解決手段】ハイギア位置及びローギア位置の一方から他方へとクラッチスリーブを移動しての副変速機20のギア段の切替を、自動変速機13がニュートラルレンジの状態にあり、かつ車両Cが停車中であることを条件に実施するとともに、ローギア位置を含むトルク制限実施範囲にクラッチスリーブが移動開始時に位置している場合にエンジン10のトルク制限を実施するトルク制限制御と、副変速機20のギア段の切替中に自動変速機13のニュートラルレンジが解除されたときにクラッチスリーブがトルク制限実施範囲に位置している場合に副変速機20のギア段を切替開始前のギア段に戻す戻し制御と、を実行する。【選択図】図1
