PROBLEM TO BE SOLVED: To provide a power train control device of a vehicle which can reduce a burden of a driver at an accelerator operation without complicating a vehicle structure.SOLUTION: In a power train control device of a vehicle having a controller 21 which controls a drive force at traveling on the basis of a drive force characteristic which indicates a target drive force corresponding to an accelerator opening, the controller 21 comprises: a tactile sensor 27 which detects a drive attitude of a driver D; an ankle burden estimation part 31 which estimates magnitude of an ankle burden at an accelerator operation of the driver D on the basis of a vertical friction force which is detected by the tactile sensor 27; and a target drive force calculation part 32 which sets the drive force characteristic to a standard characteristic, when the ankle burden is estimated to be relatively small, and changes the drive force characteristic to a correction characteristic which is smaller than the standard characteristic in the target drive force, when the ankle burden is estimated to be relatively large.

    【課題】車両構造を複雑化することなく、アクセル操作時のドライバーの負担を軽減することができる車両のパワートレイン制御装置を提供すること。【解決手段】アクセル開度に応じた目標駆動力を示す駆動力特性に基づいて走行時の駆動力を制御するコントローラ21を備えた車両のパワートレイン制御装置において、前記コントローラ21は、ドライバーDの運転姿勢を検出する触覚センサ27と、触覚センサ27によって検出された上下方向摩擦力に基づき、ドライバーDのアクセル操作時の足首負担の大きさを推定する足首負担推定部31と、足首負担が比較的小さいと推定されたときには駆動力特性を標準特性に設定し、足首負担が比較的大きいと推定されたときには駆動力特性を、標準特性よりも目標駆動力が小さい補正特性に変更する目標駆動力演算部32と、を有する構成とした。【選択図】図9
