Abstract

L'invention concerne un procédé pour réduire le patinage d'entraînement de roues de véhicule qui sont entraînées par des moteurs différents (3, 4). Le patinage d'entraînement peut être réglé de manière particulièrement simple et économique en réalisant une régulation du patinage au niveau d'un premier groupe de roues (2a, 2b) qui sont entraînées par un premier moteur (3), et en réalisant une commande du couple d'entraînement au niveau d'un deuxième groupe de roues (2c, 2d) qui sont entraînées par un deuxième moteur (4).
