A method for determining slip-page of at least one wheel of at least one vehi-cle having a motor and a processor that com-municates velocity commands to the motor for varying a velocity of the vehicle is presented. The method includes determining an actual ve-locity of the vehicle over regular intervals; comparing, over regular intervals, the actual ve-locity of the vehicle to the expected velocity from the magnitude of the velocity commands to determine whether there is slip of the wheel of the vehicle; and reducing the magnitude of the velocity commands to equal approximately the actual velocity of the vehicle where there is slip of the wheel. A system and circuit carrying out the method are also presented.

L'invention porte sur un procédé pour déterminer le dérapage d'au moins une roue d'au moins un véhicule possédant un moteur et un processeur qui communique des instructions de vitesse au moteur pour modifier une vitesse du véhicule. Le procédé comprend la détermination d'une vitesse réelle du véhicule à des intervalles réguliers; la comparaison, à des intervalles réguliers, de la vitesse réelle du véhicule avec la vitesse attendue à partir de l'amplitude des instructions de vitesse pour déterminer s'il y a un dérapage de la roue du véhicule; et la réduction de l'amplitude des instructions de vitesse pour atteindre approximativement la vitesse réelle du véhicule dans laquelle il y a un dérapage de la roue. L'invention porte également sur un système et un circuit mettant en uvre le procédé.
