Title (EN) LIQUID PRESSURE CONTROL DEVICE
(FR) DISPOSITIF DE RÉGULATION DE PRESSION DE LIQUIDE
(JA) 液圧制御装置
Abstract:
(EN) Provided is a liquid pressure control device which enables improvement in the braking feel experienced by a driver and improvement in the durability of components involved in control. The present invention is a liquid pressure control device in which a valve part is configured to allow, for a prescribed period of time, fluctuations of the actual pressure associated with the movement of a liquid in a liquid pressure chamber in accordance with, even after a retention signal is inputted, a pressure increase/decrease signal inputted prior to the input of the retention signal. The liquid pressure control device is provided with: a state determination unit that determines whether or not the state of the liquid pressure chamber is a state in which the actual pressure is fluctuating even though a retention signal has been inputted to the valve part; and a control unit that executes a specific control to maintain the actual pressure at a liquid pressure level falling within a dead zone when the state determination unit has determined that the state of the liquid pressure chamber is the fluctuating state as mentioned above.
(FR) La présente invention concerne un dispositif de régulation de pression de liquide qui permet une amélioration de la sensation de freinage subie par un conducteur et une amélioration de la durabilité de composants mis en œuvre dans la régulation. La présente invention concerne un dispositif de régulation de pression de liquide dans lequel une partie de soupape est configurée pour permettre, pendant une durée prescrite, des fluctuations de la pression réelle associées au déplacement d'un liquide dans une chambre de pression de liquide en fonction, même après qu’un signal de rétention ait été entré, d’un signal d'augmentation/diminution de pression entré avant l'entrée du signal de rétention. Le dispositif de régulation de pression de liquide est pourvu de : une unité de détermination d'état qui détermine si l'état de la chambre de pression de liquide est ou non un état dans lequel la pression réelle fluctue même si un signal de rétention a été entré dans la partie de soupape ; et une unité de commande qui exécute une commande spécifique pour maintenir la pression réelle à un niveau de pression de liquide situé dans une zone morte lorsque l'unité de détermination d'état a déterminé que l'état de la chambre de pression de liquide est l'état fluctuant comme mentionné ci-dessus.
(JA) 運転者のブレーキフィーリングを向上させ、制御に関する部品の耐久性を向上させることができる液圧制御装置を提供する。 本発明は、弁部が、保持信号が入力された後にも、その入力直前に入力されていた増減圧信号に従って、所定期間だけ液圧室内の流体の移動に伴う実圧の変動が許容されるように構成されている液圧制御装置であって、液圧室の状態が、保持信号が弁部に入力されているにもかかわらず実圧が変動している状態であるか否かを判定する状態判定部と、状態判定部により液圧室の状態が上記変動状態であることが判定されている場合に、実圧を不感帯内の液圧に維持する特定制御を実行する制御部と、を備える。
