Title (EN) BRAKING CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE DE FREINAGE
(JA) 制動制御装置
Abstract:
(EN) A braking control device in an embodiment cooperatively controls, for example, an upstream mechanism for increasing/decreasing the hydraulic pressure of a brake fluid in a master cylinder and a downstream mechanism which is connected to the upstream mechanism via a hydraulic pressure circuit and which is for increasing/decreasing the hydraulic pressure of the brake fluid output from the upstream mechanism and supplying same to a wheel cylinder, the cooperative control being performed on the basis of a target wheel pressure which is a target value for the hydraulic pressure in the wheel cylinder. The braking control device switches, when hydraulic pressure hunting occurs, the control of the downstream mechanism from an FB control based on the hydraulic pressure detected by a hydraulic pressure sensor to an FF control based on an upstream target hydraulic pressure, thereby eliminating mutual interference between control of the upstream mechanism and control of the downstream mechanism and swiftly resolving the hydraulic pressure hunting.
(FR) Dans un mode de réalisation, un dispositif de commande de freinage commande par exemple un mécanisme amont pour augmenter/réduire la pression hydraulique d'un liquide de frein dans un maître-cylindre et un mécanisme aval qui est raccordé au mécanisme amont par l'intermédiaire d'un circuit de pression hydraulique et qui est destiné à augmenter/réduire la pression hydraulique du liquide de frein délivré par le mécanisme amont et à le fournir à un cylindre de roue, la commande coopérative étant réalisée sur la base d'une pression de roue cible qui est une valeur cible pour la pression hydraulique dans le cylindre de roue. Le dispositif de commande de freinage commute, lorsque la chasse de pression hydraulique se produit, la commande du mécanisme aval à partir d'une commande FB sur la base de la pression hydraulique détectée par un capteur de pression hydraulique vers une commande FF sur la base d'une pression hydraulique cible amont, ce qui permet d'éliminer les interférences mutuelles entre la commande du mécanisme amont et la commande du mécanisme aval et de résoudre rapidement la chasse de pression hydraulique.
(JA) 実施形態における制動制御装置は、例えば、マスタシリンダ内のブレーキ液の液圧を増減する上流機構と、前記上流機構に液圧回路を介して接続され、前記上流機構から出力された液圧を増減させてホイールシリンダに供給する下流機構と、を前記ホイールシリンダ内の液圧の目標値である目標ホイール圧に基づいて協調制御する。制動制御装置は、液圧ハンチングが発生した場合、下流機構の制御を、液圧センサによる検知液圧に基づいたFB制御から、上流目標液圧に基づいたFF制御に切り替えることで、上流機構と下流機構での制御の相互干渉を無くし、液圧ハンチングを速やかに解消する。
