(FR) DISPOSITIF DE COMMANDE DE VÉHICULE ÉLECTRIQUE À QUATRE ROUES MOTRICES
Abstract: front page image
(EN) The purpose of the present invention is to prevent shock from occurring due to the intervention of regenerative control while operating in the four-wheel drive state. The drive source has a motor/generator (4), and an electronically controlled coupling (42) is provided on the drive power transmission path leading from the drive source to the front and rear wheels. This FF base four-wheel drive hybrid vehicle is comprising a 4WD control unit (85) that outputs to the electronically controlled coupling (42) a transmission torque command value to bring about the four-wheel drive state, in accordance with the vehicle state. The 4WD control unit (85) has a regenerative control intervention-coordinating controller that, when regenerative control by the motor/generator (4) has intervened during the four-wheel drive state, brings the transmission torque of the electronically controlled coupling (42) to zero before initiating regenerative control.
(FR)  La présente invention a pour objet d'empêcher la survenue d'un choc en raison de l'intervention d'une commande régénérative tout en fonctionnant dans l'état d'entraînement à quatre roues motrices. La source de puissance comprend un moteur-générateur (4), et un couplage à commande électronique (42) est agencé sur le trajet de transmission de puissance d'entraînement allant de la source de puissance aux roues avant et arrière. Ce véhicule hybride à quatre roues motrices de type traction comprend une unité de commande de quatre roues motrices (85) qui transmet au couplage à commande électronique (42) une valeur de commande de couple de transmission pour provoquer un état d'entraînement à quatre roues motrices selon l'état du véhicule. L'unité de commande de quatre roues motrices (85) comprend un dispositif de commande coordonnant l'intervention de commande régénérative qui, lorsqu'une commande régénérative par le moteur-générateur (4) est intervenue pendant l'état d'entraînement à quatre roues motrices, amène le couple de transmission du couplage à commande électronique (42) à zéro avant le début de la commande régénérative.
