Title (EN) AWD SYSTEM WITH ROAD CONDITION ANALYSIS SYSTEM
(FR) SYSTÈME DE TRANSMISSION INTÉGRALE À SYSTÈME D'ANALYSE D'ÉTAT DE LA ROUTE
Abstract:
(EN) A method of controlling a drive train of a vehicle includes collecting acceleration data from the vehicle as vehicle tires travel across a road surface. The data is analyzed to determine a condition of the road surface. The drive train is preemptively switched from a two-wheel drive mode to a four-wheel drive mode prior to a wheel slip based on the analysis of the data.
(FR) L'invention porte sur un procédé de commande d'une transmission d'un véhicule, lequel procédé comprend la collecte de données d'accélération provenant du véhicule à mesure que les pneus du véhicule se déplacent sur une surface de route. Les données sont analysées pour déterminer un état de la surface de route. La transmission est commutée de façon préventive d'un mode de transmission à deux roues motrices à un mode de transmission à quatre roues motrices avant un patinage basé sur l'analyse des données.
