要約
(EN)
A valve opening/closing timing control device capable of quickly determining that an intermediate locked phase has been attained, said control device being equipped with: an intermediate lock mechanism capable of switching between a locked state, wherein a lock member provided on a drive-side rotary member protrudes and fits into a recess provided on a driven-side rotary member, thereby holding the relative rotational phase in an intermediate locked phase, and an unlocked state, wherein the lock member withdraws from the recess, thereby releasing the hold; a phase control unit that controls the supply of fluid to a retard chamber and the discharge of fluid from an advance chamber, or controls the discharge of fluid from the retard chamber and the supply of fluid to the advance chamber, so as to enable the lock member to attain the intermediate locked phase; and a determination unit which, after the execution of a control whereby fluid is supplied to the retard chamber and fluid is discharged from the advance chamber or whereby fluid is discharged from the retard chamber and fluid is supplied to the advance chamber, and the lock member is controlled so as to move toward a determination phase that has been set at a different positon than the intermediate locked phase in the recess, determines whether the lock member has attained the determination phase. When the result of the determination is that the lock member has not attained the determination phase, the determination unit determines that the relative rotation phase is in the locked state.

La présente invention concerne un dispositif de commande de synchronisation d'ouverture/fermeture de soupape pouvant déterminer rapidement qu'une phase verrouillée intermédiaire a été atteinte, ledit dispositif de commande étant équipé de : un mécanisme de verrouillage intermédiaire pouvant commuter entre un état verrouillé, dans lequel un organe de verrouillage placé sur un organe rotatif du côté d'entraînement fait saillie et s'adapte dans un évidement placé sur un organe rotatif du côté entraîné, ce qui permet de bloquer la phase de rotation relative dans un état verrouillé intermédiaire, et un état déverrouillé, dans lequel l'organe de verrouillage se retire de l'évidement, ce qui permet de libérer le blocage ; une unité de commande de phase qui commande l'alimentation d'un fluide dans une chambre de retard et l'évacuation du fluide d'une chambre d'avance, ou commande l'évacuation du fluide de la chambre de retard et l'alimentation du fluide dans la chambre d'avance, de façon à permettre à l'organe de verrouillage d'atteindre la phase verrouillée intermédiaire ; et une unité de détermination qui, après l'exécution d'une commande par laquelle le fluide est alimenté dans la chambre de retard et le fluide est évacué de la chambre d'avance, ou par laquelle le fluide est évacué de la chambre de retard et le fluide est alimenté dans la chambre d'avance, et après que l'organe de verrouillage est commandé de façon à se déplacer vers une phase de détermination qui a été définie en une position différente de celle de la phase verrouillée intermédiaire dans l'évidement, détermine si l'organe de verrouillage a atteint la phase de détermination. Lorsque le résultat de la détermination est que l'organe de verrouillage n'a pas atteint la phase de détermination, l'unité de détermination détermine que la phase de rotation relative est dans l'état verrouillé.

中間ロック位相への到達を迅速に判定可能な弁開閉時期制御装置は、駆動側回転部材に設けられたロック部材が突出して、従動側回転部材に設けられた凹部に嵌入することにより相対回転位相を中間ロック位相に拘束するロック状態と、ロック部材が凹部から引退することにより拘束が解除されたロック解除状態とに切り替え可能な中間ロック機構と、ロック部材が中間ロック位相に達するように、遅角室への流体の供給及び進角室からの流体の排出、又は遅角室からの流体の排出及び進角室への流体の供給を制御する位相制御部と、当該遅角室への流体の供給及び進角室からの流体の排出と、遅角室からの流体の排出及び進角室への流体の供給との一方の制御を実施した後に、ロック部材が凹部における中間ロック位相とは異なる位置に設定された判定位相に向かって移動するように制御された時、当該判定位相にロック部材が達するか否かを判定し、判定結果に基づき、ロック部材が判定位相に未到達であると判定したとき、相対回転位相がロック状態であると判定する判定部と、を備える。
