Title (EN) BRAKE CONTROL DEVICE FOR VEHICLE
(FR) DISPOSITIF DE COMMANDE DE FREIN POUR VÉHICULE
(JA) 車両の制動制御装置
Abstract:
(EN) A control device 100 is provided with: a flow rate derivation part 143 for deriving a pressure-holding-valve flow rate on the basis of a WC pressure command value and a previous WC pressure command value; a differential pressure derivation part 144 for deriving a differential-pressure-valve differential pressure value so that the differential-pressure-valve differential pressure value increases with an increase in the difference obtained by subtracting the pressure-holding-valve flow rate from a pump-discharge flow rate; and a pressure-holding-valve processing part 145 for performing an aperture derivation process to derive a command aperture so that the command aperture decreases with an increase in the difference obtained by subtracting the WC pressure command value from the sum of an MC pressure value and the differential-pressure-valve differential pressure value, and driving a holding pressure valve 64 at the command aperture.
(FR) L'invention concerne un dispositif de commande (100) pourvu : d'une partie de dérivation de débit (143) pour dériver un débit de soupape de maintien de pression sur la base d'une valeur d'instruction de pression de WC et d'une valeur d'instruction de pression de WC précédente ; d'une partie de dérivation de pression différentielle (144) pour dériver une valeur de pression différentielle de soupape de pression différentielle de telle sorte que la valeur de pression différentielle de soupape de pression différentielle augmente avec une augmentation de la différence obtenue en soustrayant le débit de soupape de maintien de pression d'un débit de refoulement de pompe ; et d'une partie de traitement de soupape de maintien de pression (145) pour effectuer un processus de dérivation d'ouverture pour dériver une ouverture d'instruction de telle sorte que l'ouverture d'instruction diminue avec une augmentation de la différence obtenue en soustrayant la valeur d'instruction de pression de WC de la somme d'une valeur de pression de MC et de la valeur de pression différentielle de soupape de pression différentielle et en entraînant une soupape de pression de maintien (64) au niveau de l'ouverture d'instruction.
(JA) 制御装置100は、WC圧指示値とWC圧指示値の前回値とを基に保持弁通過流量を導出する通過流量導出部143と、ポンプ吐出流量から保持弁通過流量を減じた差が大きいほど差圧弁差圧が大きくなるように、差圧弁差圧を導出する差圧導出部144と、MC圧と差圧弁差圧との和からWC圧指示値を減じた差が大きいほど指示開度が小さくなるように、指示開度を導出する開度導出処理を実施し、この指示開度で保持弁64を駆動させる保持弁処理部145とを備える。
