Title (EN) METHOD AND APPARATUS FOR CONTROLLING DIFFERENTIALLY DRIVEN WHEEL SLIP
(FR) PROCEDE ET APPAREIL DE COMMANDE DU PATINAGE DES ROUES ENTRAINEES DIFFERENTIELLEMENT
Abstract: front page image
(EN)A slip control system for vehicles having spaced apart differentially driven wheels (200, 202) including means (220) for calculating wheel slip according to the ratio of wheel speeds, means (242, 230, 232) for entering a slip control mode wherein a braking force is applied to the slipping wheel and incrementally varied on a periodic review basis according to recalculated slip values. If slip increases or holds steady, the brake force is incrementally increased. As slip becomes less, the brake force is incrementally reduced, the particular increments of force reduction being selected in accordance with successive measurements of slip. A drive shaft signal (226) is compared to the high wheel speed signal to identify a wheel speed transducer failure.
(FR)Un systeme de commande du patinage pour des vehicules ayant des roues espacees entrainees differentiellement (200, 202) comprend des moyens (220) pour calculer le patinage des roues en fonction du rapport des vitesses des roues, des moyens (242, 230, 232) pour entrer un mode de commande de patinage ou une force de freinage est appliquee a la roue qui patine et on fait varier par increments cette force periodiquement d"apres des valeurs de patinage recalculees. Si le patinage augmente ou persiste, la force de freinage est augmentee par increments. Lorsque le patinage diminue, la force de freinage est reduite par increments, les increments particuliers de reduction de la force etant choisis en fonction des mesures successives du patinage. Un signal de l"arbre de transmission (226) est compare au signal de vitesse elevee d"une roue pour identifier la defaillance d"un transducteur de vitesse d"une roue.
