PROBLEM TO BE SOLVED: To shorten the time for engagement instruction pressure of an engagement element to reach optimal pressure in a drive control apparatus for a vehicle that is provided with a transmission including the engagement element having a clutch pack.SOLUTION: A drive control apparatus is used for a hybrid vehicle that includes an engine, a second motor, and an automatic transmission having an input shaft directly connected to the second motor. The apparatus includes: input torque estimation means (S2) for estimating AT input torque on the basis of output torque of the second motor in the case of changing gears of the automatic transmission during a travel on drive power of the second motor; and learning means (S4-S7) for obtaining, as a learning value, packing pressure on the basis of engagement instruction pressure at the time of inertia phase start in the case of the estimated input torque being within a prescribed range (S3). Further learning means is configured so as to set a correction amount based on the learning value obtained during an EHV travel at a value larger than a correction amount based on the learning value obtained during an EV travel.SELECTED DRAWING: Figure 6

    【課題】クラッチパックを有する係合要素を含む変速機を備えた車両の駆動制御装置において、係合要素の係合指示圧が最適圧へ到達するまでの時間を短縮する。【解決手段】エンジンと、第2電動機と、入力軸が第2電動機に直結される自動変速機と、を備えるハイブリッド車両の駆動制御装置である。第2電動機の駆動力を用いた走行中に自動変速機の変速を行う場合に、第2電動機の出力トルクに基づいてAT入力トルクを推定する入力トルク推定手段(S2)と、推定入力トルクが所定範囲内にある場合(S3)に、イナーシャ相開始時点での係合指示圧に基づいてパック詰め圧を学習値として取得し、学習値に基づいて係合指示圧を補正する学習手段(S4〜S7)と、を備えている。学習手段は、EV走行時に取得した学習値に基づく補正量を、EHV走行時に取得した学習値に基づく補正量よりも大きくするように構成されている。【選択図】図6
