Abstract[English]
A vehicle (1) includes a controllable clutch (30) with a variable clutch engagement ratio. The clutch (30) is arranged between a front axle drive output shaft (25) connected with a front axle (12) and a rear axle drive output shaft (29) connected with a rear axle (14) of the vehicle (1). A control unit (5) may determine a speed difference (V_d) between the front and rear axle drive output shafts (25, 29) and reduce the speed difference (V_d) if the speed difference (V_d) exceeds a threshold value. The threshold value may depend on a pull force of the vehicle (1) and a normalized rotational speed value of the rear axle drive output shaft (29).[French]
Un véhicule (1) comporte un embrayage pouvant être commandé (30) avec un rapport de mise en prise d'embrayage variable. L'embrayage (30) est agencé entre un arbre de sortie d'entraînement d'essieu avant (25) relié à un essieu avant (12) et un arbre de sortie d'entraînement d'essieu arrière (29) relié à un essieu arrière (14) du véhicule (1). Une unité de commande (5) peut déterminer une différence de vitesse (V_d) entre les arbres de sortie d'entraînement d'essieu avant et arrière (25, 29) et réduire la différence de vitesse (V_d) si la différence de vitesse (V_d) dépasse une valeur seuil. La valeur seuil peut dépendre d'une force de traction du véhicule (1) et d'une valeur de vitesse de rotation normalisée de l'arbre de sortie d'entraînement d'essieu arrière (29).
