Title (EN) FOUR-WHEEL DRIVE VEHICLE CONTROL SYSTEM AND METHODS
(FR) SYSTÈME ET PROCÉDÉS DE COMMANDE DE VÉHICULE À QUATRE ROUES MOTRICES
Abstract:
(EN) Methods and systems are provided for operating a four-wheel drive powertrain of a vehicle. In one example, a method may comprise: in response to a desired shift from a four- wheel drive mode to a two wheel-drive mode: decreasing a transfer case torque output to a secondary driveline to a lower first level and disengaging a disconnect device of the secondary driveline; increasing the transfer case torque output from the lower first level to a higher second level over a duration; and after the duration, reducing the transfer case torque.
(FR) L'invention concerne des procédés et des systèmes utilisés pour faire fonctionner un groupe motopropulseur à quatre roues motrices d'un véhicule. Dans un exemple, un procédé peut comprendre : en réponse à un changement souhaité d'un mode quatre roues motrices à un mode deux roues motrices : la réduction d'un couple de boîte de transfert produit en sortie vers une chaîne cinématique secondaire à un premier niveau inférieur et le désaccouplement d'un dispositif de déconnexion de la chaîne cinématique secondaire; l'augmentation du couple de boîte de transfert produit en sortie pour passer du premier niveau inférieur à un second niveau supérieur pendant une durée; et après cette durée, la réduction du couple de boîte de transfert.
