Description
まず図2を参照して、フューエルカット制御から復帰した後に、減速S&S制御を実施する場合の車両制御装置2の動作について説明する。図2のタイムチャートには、回転数、LU指示圧(ロックアップクラッチ24への供給油圧の指令値)、C1指示圧(C1クラッチ36への供給油圧の指令値)、エンジン点火時期、D/Sトルク(動力伝達経路のドライブシャフト19で発生するトルク)の時間遷移がそれぞれ示されている。 First, with reference to FIG. 2, the operation of the vehicle control device 2 when the deceleration S & S control is performed after returning from the fuel cut control will be described. In the time chart of FIG. 2, the rotational speed, LU command pressure (command value of hydraulic pressure supplied to the lockup clutch 24), C1 command pressure (command value of hydraulic pressure supplied to the C1 clutch 36), engine ignition timing, D / Time transitions of S torque (torque generated in the drive shaft 19 of the power transmission path) are shown.
時刻t2において、ロックアップクラッチ24の開放が完了すると共に、フューエルカット制御から復帰する。このとき、エンジンの点火時期が遅角側に設定されてエンジン10への燃料噴射が再開される。ロックアップクラッチ24の開放に伴い、D/Sトルクが急激に増大し振動しはじめる。つまり、D/Sトルクは、ロックアップクラッチ24の開放後の時刻t2以降では、エンジン10を引き摺っていた負荷が急に抜けて揺り返しを生じている。 At time t2, the release of the lockup clutch 24 is completed and the fuel cut control is resumed. At this time, the ignition timing of the engine is set to the retard side, and fuel injection to the engine 10 is resumed. As the lock-up clutch 24 is released, the D / S torque suddenly increases and starts to vibrate. That is, the D / S torque swings back after the time t2 after the lock-up clutch 24 is released and the load that is dragging the engine 10 suddenly comes off.
時刻t4にてクラッチ36の開放が完了した後には、エンジン10側からドライブシャフト19側へのトルク伝達は無くなる。但し、クラッチ36からドライブシャフト19側の動力伝達経路の引き摺り分の影響により、図2に示すように、D/Sトルクは時刻t4以降では僅かにゼロ以下で一定となっている。また、時刻t4にてクラッチ36の開放が完了した後には、図2には図示しないが減速S&S制御によりエンジン10が停止される。 After the release of the clutch 36 is completed at time t4 , torque transmission from the engine 10 side to the drive shaft 19 side is lost. However, due to the drag of the power transmission path on the drive shaft 19 side from the clutch 36, as shown in FIG. 2, the D / S torque is constant at slightly below zero after time t4. Further, after the release of the clutch 36 is completed at time t4, the engine 10 is stopped by the deceleration S & S control (not shown in FIG. 2).
