Title
(EN) CONTROL DEVICE FOR IN-VEHICLE POWER SOURCE DEVICE
(FR) DISPOSITIF DE COMMANDE POUR UN DISPOSITIF D'ALIMENTATION ÉLECTRIQUE EMBARQUÉ
(JA) 車載電源装置の制御装置
Abstract
(EN) A control device (21) for an onboard power source device is applied to an onboard power source device comprising: a storage battery (11) connected to an electric apparatus (14); a switch (SW1) provided to an electric route (L1) joining the storage battery and the electric apparatus; and a first voltage sensor (25) and second voltage sensor (26) that detect a voltage that is on the storage-battery side, among the two ends of the switch. When the voltage that is on the storage-battery side, among the two ends of the switch, is a prescribed overvoltage, turning the switch on is prohibited. The control device comprises a voltage acquisition unit that acquires a first voltage detected by the first voltage sensor and a second voltage detected by the second voltage sensor, and a switch control unit that allows the switch to be turned on when one of the first voltage and the second voltage is a normal value and the other is an overvoltage value.
(FR) La présente invention concerne un dispositif de commande (21) pour un dispositif de source d'alimentation embarqué, ledit dispositif de commande étant appliqué à un dispositif de source d'alimentation embarqué comprenant : une batterie de stockage (11) raccordée à un appareil électrique (14) ; un commutateur (SW1) disposé sur un itinéraire électrique (L1) reliant la batterie de stockage et l'appareil électrique ; et un premier capteur de tension (25) et un second capteur de tension (26) qui détectent une tension qui est du côté de la batterie de stockage, parmi les deux extrémités du commutateur. Lorsque la tension qui est du côté de la batterie de stockage, parmi les deux extrémités du commutateur, est une surtension prescrite, la mise sous tension du commutateur est empêchée. Le dispositif de commande comprend une unité d'acquisition de tension qui acquiert une première tension détectée par le premier capteur de tension et une seconde tension détectée par le second capteur de tension, et une unité de commande de commutation qui permet au commutateur d'être activé lorsque l'une de la première tension et de la seconde tension est une valeur normale et que l'autre est une valeur de surtension.
(JA) 車載電源装置の制御装置(21)は、電気機器(14)に接続される蓄電池(11)と、蓄電池及び電気機器を繋ぐ電気経路(L1)に設けられたスイッチ(SW1)と、スイッチの両端のうち蓄電池の側の電圧を検出する第1電圧センサ(25)及び第2電圧センサ(26)と、を備える車載電源装置に適用され、スイッチの両端のうち蓄電池の側の電圧が所定の過大電圧である場合に、スイッチをオンすることを禁止する。制御装置は、第1電圧センサにより検出された第1電圧、及び第2電圧センサにより検出された第2電圧を取得する電圧取得部と、第1電圧及び第2電圧のうち一方が正常値であり、他方が過大電圧値である場合に、スイッチをオンすることを許可するスイッチ制御部と、を備える。
