Abstract
(EN) A control method and system after a hybrid vehicle battery failure, and a hybrid vehicle. The control method comprises: after monitoring that a failure occurs to a power battery, determining whether the failure is a specific type of failure, the specific type of failure being a battery failure where a motor of a hybrid vehicle can perform voltage control (S402); if yes, configuring a relay of the power battery to be turned off after a preset time (S404); before the relay is turned off, performing coordination control on the power battery, an engine, a transmission, and the motor of the hybrid vehicle, so that the running states of the power battery, the engine, the transmission, and the motor satisfy preset voltage control entry conditions (S406); and controlling the motor to enter a voltage control mode (S408).In this way, the motor can smoothly enter the voltage control mode and stably runs, and the problems such as battery overtemperature and severe voltage fluctuation caused by directly performing voltage control by the motor after the failure occurs to the power battery are avoided.
(FR) La présente invention concerne un procédé et un système de commande après une défaillance de batterie de véhicule hybride et un véhicule hybride. Le procédé de commande comprend : après la surveillance d'une apparition de défaillance dans une batterie d'alimentation, la détermination si oui ou non la défaillance est un type spécifique de défaillance, le type spécifique de défaillance étant une défaillance de batterie où un moteur électrique d'un véhicule hybride peut réaliser une commande de tension (S402); si tel est le cas, la configuration d'un relais de la batterie d'alimentation pour son extinction après un temps prédéfini (S404); avant l'extinction du relais, la réalisation d'une commande de coordination sur la batterie d'alimentation, un moteur, une transmission et le moteur électrique du véhicule hybride, de sorte que les états de fonctionnement de la batterie d'alimentation, du moteur, de la transmission et du moteur électrique remplissent des conditions d'entrée de commande de tension prédéfinies (S406); et la commande du moteur électrique pour son entrée dans un mode de régulation de tension (S408). De cette manière, le moteur peut entrer sans à-coups dans le mode de régulation de tension et fonctionne de manière stable, et les problèmes tels qu'une température excessive de batterie et une fluctuation de tension sévère provoqués par la réalisation directe d'une commande de tension par le moteur électrique après l'apparition de la défaillance sont évités.
(ZH) 一种混合动力车辆电池故障后的控制方法和系统以及混合动力车辆。该控制方法包括:在监测到动力电池发生故障后,判断故障是否为特定类型故障,其中,特定类型故障为混合动力车辆的电机在其下可进行电压控制的电池故障(S402);若是,设置动力电池的继电器在预设时间后断开(S404);在继电器断开前,协调控制混合动力车辆的动力电池、发动机、变速器和电机,使它们的运行状态满足预设的电压控制进入条件(S406);控制电机进入电压控制模式(S408)。可使电机顺利进入电压控制且运行平稳,避免在动力电池故障后直接进行电机的电压控制而导致的电池超温、电压波动严重等问题。
