| description | To suppress a reduction in the learning frequency while suppressing erroneous learning of packing learning of a lockup clutch when starting or stopping an engine is overlapped while executing the packing learning.SOLUTION: During execution of packing learning, in a case where an engine is started or stopped when an elapsed period of time from a start point of packing control is longer than a target value of a packing completion time, a point of time of starting or stopping the engine is determined to be a point of time where the packing is completed, and instruction pressure of a lockup clutch to be used for the next packing control is corrected toward higher pressure side. Therefore, in a case where the instruction pressure of the lockup clutch is determined to be in shortage at the point in time of starting or stopping the engine, the instruction pressure can be corrected toward higher pressure, and it is possible to prevent the packing completion time from being unstably calculated during a start transition or stop transition of the engine.SELECTED DRAWING: Figure 3
【課題】ロックアップクラッチのパック詰め学習の実行中にエンジンの始動又は停止が重なる際に、パック詰め学習の誤学習を抑制しつつ学習頻度の低下を抑制する。【解決手段】パック詰め学習の実行中において、パック詰め制御の開始時点からの経過時間がパック詰め完了時間の目標値よりも長くなっているときに、エンジンの始動又は停止が開始された場合には、エンジンの始動又は停止が開始された時点がパック詰め完了状態とされた時点と判断されると共に、次回のパック詰め制御に用いられるロックアップクラッチの指示圧が増圧側に補正されるので、エンジンの始動又は停止の開始時点でロックアップクラッチの指示圧が不足していると判断できるときにはその指示圧を増圧側に補正することができると共に、エンジンの始動過渡中又は停止過渡中にパック詰め完了時間が不安定に算出されることが回避される。【選択図】図３ |
