Abstract:
(EN) The purpose of the present invention is to enable stable braking without being affected by age-related deterioration of a brake device or the like. The brake ECU 30 of a vehicle 1 has a brake device 11 capable of adjusting the braking force according to supplied hydraulic pressure. The vehicle 1 is provided with a master pressure sensor 17 for measuring the hydraulic pressure supplied to the brake device 11, and a G sensor 44 and wheel speed sensor 12 for measuring acceleration information whereby the acceleration of the vehicle 1 can be detected. The brake ECU 30 is configured so as to comprise a pressure command value calculation section 36 that determines, on the basis of a preset coefficient, the hydraulic pressure to be supplied to the brake device 11 at the time of deceleration of the vehicle 1 and supplies the determined hydraulic pressure to the brake device 11, and a brake torque coefficient calculation section 31 that, on the basis of the relationship between the hydraulic pressure and acceleration, learns a candidate coefficient serving as a candidate in changing the coefficient and changes the coefficient to the candidate coefficient.
(FR) Le but de la présente invention est de permettre un freinage stable sans être affecté par la détérioration liée à l'âge d'un dispositif de frein ou similaire. L'ECU de frein 30 d'un véhicule 1 comporte un dispositif de frein 11 pouvant régler la force de freinage en fonction d'une pression hydraulique apportée. Le véhicule 1 est pourvu d'un capteur de pression maître 17 pour mesurer la pression hydraulique apportée au dispositif de frein 11, et d'un capteur G 44 et d'un capteur de vitesse de roue 12 pour mesurer des informations d'accélération, l'accélération du véhicule 1 pouvant être détectée. L'ECU de frein 30 est conçue de façon à comprendre une section de calcul de valeur d'instruction de pression 36 qui détermine, sur la base d'un coefficient prédéfini, la pression hydraulique à apporter au dispositif de frein 11 au moment du ralentissement du véhicule 1 et apporte la pression hydraulique déterminée au dispositif de frein 11, et une section de calcul de coefficient de couple de frein 31 qui, sur la base de la relation entre la pression hydraulique et l'accélération, apprend un coefficient candidat servant de candidat pour le changement du coefficient et change le coefficient par rapport au coefficient candidat.
(JA) 制動装置の経年劣化等の影響によらず、安定した制動を実現することができるようにする。 供給される液圧に応じて制動力を調整可能な制動装置11を有する車両1の制動ECU30であって、車両1は、制動装置11に供給される液圧を測定するマスター圧センサ17と、車両1の加速度を検出可能な加速度情報を測定するGセンサ44及び車輪速センサ12と、を備え、予め設定された係数に基づいて、車両1の減速時に制動装置11に供給する液圧を決定し、決定された液圧を制動装置11に供給させる圧力指令値演算部36と、液圧と、加速度との関係に基づいて、係数を変更する候補となる係数候補を学習し、係数を係数候補に変更する制動トルク係数演算部31と、を備えるように構成する。
