Title (EN) ELECTRIC BRAKING DEVICE AND CONTROLLER
(FR) DISPOSITIF DE FREINAGE ÉLECTRIQUE ET CONTRÔLEUR
(JA) 電動ブレーキ装置、および、コントローラ
Abstract:
(EN) The present invention allows a redundant braking device for higher reliability to be installed in less space. This electric braking device is disposed distributed between the vehicle body side and the wheel side of a vehicle, the wheel side being provided with a motor for delivering braking power to the wheels, a first motor drive unit for driving a first winding group of the motor, and a second motor drive unit for driving a second winding group of the motor, and the vehicle body side being provided with a controller for controlling the first motor drive unit and the second motor drive unit. A first communication line that connects the first motor drive unit and the controller, and a second communication line that connects the second motor drive unit and the controller, are provided between the vehicle body side and the wheel side.
(FR) La présente invention permet à un dispositif de freinage redondant servant à une fiabilité accrue d'être installé dans moins d'espace. Le dispositif de freinage électrique est disposé de manière distribuée entre le côté carrosserie de véhicule et le côté roue d'un véhicule, le côté roue étant pourvu d'un moteur destiné à fournir une puissance de freinage aux roues, d'une première unité d'excitation de moteur destinée à exciter un premier groupe d'enroulements du moteur, et d'une deuxième unité d'excitation de moteur destinée à exciter un deuxième groupe d'enroulements du moteur, et le côté carrosserie de véhicule étant pourvu d'un contrôleur destiné à commander la première unité d'excitation de moteur et la deuxième unité d'excitation de moteur. Une première ligne de communication qui relie la première unité d'excitation de moteur et le contrôleur, et une deuxième ligne de communication qui relie la deuxième unité d'excitation de moteur et le contrôleur, sont disposées entre le côté carrosserie de véhicule et le côté roue.
(JA) 高信頼化のために冗長化したブレーキ装置を省スペースで設置させる。 本発明の電動ブレーキ装置は、車両の車体側と車輪側に分散して配置され、前記車輪側には、車輪に制動力を与えるモータと、該モータの第一の巻線組を駆動する第一のモータ駆動部と、前記モータの第二の巻線組を駆動する第二のモータ駆動部と、を設け、前記車体側には、前記第一のモータ駆動部と前記第二のモータ駆動部を制御するコントローラを設け、前記車体側と前記車輪側の間には、前記第一のモータ駆動部と前記コントローラを接続する第一の通信線と、前記第二のモータ駆動部と前記コントローラを接続する第二の通信線と、を設けた。
