Title
(EN) MULTI-WHEEL DRIVE HYBRID VEHICLE WITH MULTI-MODE FUNCTIONALITY
(FR) VÉHICULE HYBRIDE À ROUES MOTRICES MULTIPLES À FONCTIONNALITÉ MULTI-MODE
Abstract
(EN) The present disclosures relate to methods and systems for a hybrid powertrain. The hybrid powertrain system includes an integrated axle configured to provide mechanical power to a first pair of wheels, the integrated axle comprising a first motor-generator and a first drive axle such that the first motor-generator and at least a portion of the first drive axle are mechanically coupled to a common housing. The system also includes a second motor-generator configured to be mechanically coupled with an engine via a first clutch and mechanically coupled with a second drive axle via a second clutch, the second drive axle mechanically coupled with a second pair of wheels. A controller is electrically coupled with the first and second motor-generators, the engine, and the first and second clutches, the controller configured to enable a fully electric mode, a series hybrid mode, a parallel hybrid mode, and a regenerative mode of operation.
(FR) Les présentes divulgations concernent des procédés et des systèmes pour un groupe motopropulseur hybride. Le système de groupe motopropulseur hybride comprend un essieu intégré conçu pour fournir de l'énergie mécanique à une première paire de roues, l'essieu intégré comprenant un premier moteur-générateur et un premier essieu moteur de telle sorte que le premier moteur-générateur et au moins une partie du premier essieu moteur soient accouplés mécaniquement à un boîtier commun. Le système comprend également un second moteur-générateur conçu pour être accouplé mécaniquement à un moteur par l'intermédiaire d'un premier embrayage et accouplé mécaniquement à un second essieu moteur par l'intermédiaire d'un second embrayage, le second essieu moteur étant accouplé mécaniquement à une seconde paire de roues. Un dispositif de commande est couplé électriquement aux premier et second moteurs-générateurs, au moteur et aux premier et second embrayages, le dispositif de commande étant conçu pour permettre un mode entièrement électrique, un mode hybride série, un mode hybride parallèle et un mode de fonctionnement régénératif.
