A method and a system for controlling braking of a waist steered engine powered work vehicle (1) having wheels and a steering joint (4) in the form of a bucket loader having a loading bucket and at least two wheel axes, said vehicle exhibiting individually activated braking units (16-19) for each one of the wheels (2a,b,3a,b), and a transmission including a driving gear (13) for transferring of torque to a propeller axis (11) between the wheel axes (20,21), and a differential gear (14,15) between the propeller axis and each one of the wheel axes as well as a rotational rigid cardan joint in the area of the steering joint. At least one is-value is sensed or calculated for at least one condition variable influencing the vehicle, which is representative for parasitic torque occurring in the vehicle transmission during braking, and outgoing from said is-value at least one braking unit (16- 19) is controlled for reducing the magnitude of applied braking force and thereby for reduction of said parasitic torque. The invention also concerns a work vehicle (1).

L'invention concerne un procédé et un système permettant de commander le freinage d'un véhicule de travail (1) propulsé par un moteur guidé à la taille présentant des roues et un joint de guidage (4) en forme de chargeuse à godet dotée d'un godet de chargement et d'au moins deux axes de roues. Ledit véhicule présente : des unités de frein actionnées individuellement (16-19) pour chacune des roues (2a,b, 3a,b), et une transmission comportant une roue motrice (13) pour le transfert de couple vers un axe de propulsion (11) entre les axes de roues (20, 21), et un engrenage différentiel (14, 15) entre l'axe de propulsion et chacun des axes de roue, ainsi qu'un joint de cardan rigide rotatif dans la zone du joint de guidage. Au moins une valeur donnée est détectée ou calculée pour au moins une variable d'état influençant le véhicule, qui est représentative d'un couple parasite survenant dans la transmission du véhicule durant le freinage, et découlant de ladite valeur donnée, au moins une unité de freinage (16-19) est commandée de façon à réduire l'amplitude de la force de freinage appliquée, ce qui permet de réduire le couple parasite. L'invention concerne également un véhicule de travail (1).
