Claims (1)
化をともなう調整が行われるようしたエンジンか
らの動力を入力され、各種摩擦要素の選択的油圧
作動の切換えにより変速を行うようにした自動変
速機において、 前記調整を検知するエンジン調整検知手段と 前記切換えにより作動されることとなつた摩擦
要素の作動進行中における作動油圧を、前記調整
にともなうトルク変化に応じて補正する作動油圧

変速機の変速油圧制御装置。[Scope of Utility Model Registration Claim] Power is input from an engine in which adjustments are made that involve torque changes that are different from the driver's accelerator operation, and gears are changed by selectively switching hydraulic operation of various friction elements. In the automatic transmission, the engine adjustment detection means detects the adjustment, and the hydraulic pressure during the operation of the friction element that is activated by the switching is corrected in accordance with the torque change accompanying the adjustment. 1. A shift hydraulic control device for an automatic transmission, comprising a hydraulic pressure correction means.
