Summary:To perform the panic neutral control on the basis of the criterion set according to the normal or abnormal status of an ABS device.SOLUTION: A control apparatus of an automatic transmission equipped with a torque converter having a lock-up clutch capable of connecting an engine output axis and an automatic transmission input axis, comprises: a release determination part, when a brake operation is detected, for determining whether the engagement state of an engagement mechanism, which constitutes a gear stage of the automatic transmission which has been set, is to be released on the basis of the deceleration and the reference deceleration; a control part for controlling the engagement mechanism on the basis of the determination of the release determination part; and a storage part for storing the set gear stage of the automatic transmission and an engagement state of the engagement mechanism constituting the gear stage when a brake operation is detected during traveling. The control part controls the engagement mechanism to return to the gear stage stored in the storage part when returning from the released state to the engaged state.SELECTED DRAWING: Figure 7 【課題】ABS装置の正常、または異常の状態別に設定した判定基準に基づいてパニックニュートラル制御を行うこと。【解決手段】エンジンの出力軸と自動変速機の入力軸とを連結可能なロックアップクラッチを有するトルクコンバータを備えた自動変速機の制御装置は、ブレーキ操作が検出されたときに、設定されている自動変速機の変速段を構成する係合機構の係合状態を解放状態にするか否かを、減速度および基準減速度に基づいて判定する解放判定部と、解放判定部の判定に基づいて、係合機構を制御する制御部と、走行中においてブレーキ操作が検出されたときに、設定されている自動変速機の変速段と、変速段を構成する係合機構の係合状態と、を記憶する記憶部と、を備える。制御部は、解放状態から係合状態に復帰する場合、記憶部に記憶されている変速段へ復帰するように係合機構を制御する。【選択図】図7
