(ZH) 混合动力汽车及其动力系统
Abstract:
(EN) Disclosed are a hybrid vehicle (200) and a power system (100) thereof, wherein the power system (100) comprises: an engine (1); a power motor (2), the power motor (2) comprising a power motor controller (21), and the power motor controller (21) comprising a first regulator (211); a power battery (3); a DC-DC converter (4); an assistant motor (5), the assistant motor (5) comprising an assistant motor controller (51), and the assistant motor controller (51) comprising an inverter (511) and a second regulator (512); and a voltage stabilizing circuit (6) connected between the assistant motor (5) and the DC-DC converter (4), the voltage stabilizing circuit (6) performing a voltage stabilizing treatment on the direct current that is output to the DC-DC converter (4) when the assistant motor (5) generates power, wherein the second regulator (512) is used to control the voltage stabilizing treatment of the voltage stabilizing circuit (6) when the connection between the power battery (3) and the DC-DC converter (4) is cut off and the assistant motor controller (51) is in effect, and the first regulator (211) is used to control the voltage stabilizing treatment of the voltage stabilizing circuit (6) when the connection between the power battery (3) and the DC-DC converter (4) is cut off and the assistant motor controller (51) fails, such that the output voltage of the DC-DC converter (4) is kept stable in the case where the power battery (3) fails or where both the power battery (3) and the assistant motor controller (51) fail, etc.
(FR) L'invention concerne un véhicule hybride (200) et un système électrique (100) de celui-ci, lequel système électrique (100) comprend : un moteur à combustion (1) ; un moteur électrique (2), le moteur électrique (2) comprenant un dispositif de commande de moteur électrique (21), et le dispositif de commande de moteur électrique (21) comprenant un premier régulateur (211) ; une batterie de puissance (3) ; un convertisseur courant continu-courant continu (4) ; un moteur d'assistance (5), le moteur d'assistance (5) comprenant un dispositif de commande de moteur d'assistance (51), et le dispositif de commande de moteur d'assistance (51) comprenant un onduleur (511) et un second régulateur (512) ; et un circuit de stabilisation de tension (6) connecté entre le moteur d'assistance (5) et le convertisseur courant continu-courant continu (4), le circuit de stabilisation de tension (6) effectuant un traitement de stabilisation de tension sur le courant continu qui est délivré au convertisseur courant continu-courant continu (4) quand le moteur d'assistance (5) génère de l'énergie, le second régulateur (512) étant utilisé pour commander le traitement de stabilisation de tension du circuit de stabilisation de tension (6) quand la connexion entre la batterie de puissance (3) et le convertisseur continu-courant continu (4) est interrompue et que le dispositif de commande de moteur d'assistance (51) est en fonctionnement, et le premier régulateur (211) étant utilisé pour commander le traitement de stabilisation de tension du circuit de stabilisation de tension (6) quand la connexion entre la batterie de puissance (3) et le convertisseur continu-courant continu (4) est interrompue et que le dispositif de commande de moteur d'assistance (51) subit une défaillance, de telle sorte que la tension de sortie du convertisseur continu-courant continu (4) est maintenue stable dans le cas où la batterie de puissance (3) subit une défaillance, ou bien dans le cas où la batterie de puissance (3) et le dispositif de commande de moteur d'assistance (51) subissent tous deux une défaillance, etc.
