METHOD AND APPARATUS FOR CONTROLLING DIFFERENTIALLY DRIVEN WHEEL SLIP FOR AN ARTICULATED VEHICLE
An anti-spin apparatus (100) for a vehicle is disclosed. The vehicle is articulated and has at least one axle set (118) with at least two driven wheels (101, 103). The anti-spin apparatus (100) includes braking mechanisms (131, 133) which controllably apply braking forces to each of the driven wheel...

| description | An anti-spin apparatus (100) for a vehicle is disclosed. The vehicle is articulated and has at least one axle set (118) with at least two driven wheels (101, 103). The anti-spin apparatus (100) includes braking mechanisms (131, 133) which controllably apply braking forces to each of the driven wheels. A controller (160) produces a slip signal having a value responsive to the difference in rotational velocity between the wheels (101, 103) of the axle set (118). A transducer (165) produces an articulation signal having a value responsive to the angle of articulation of the vehicle. Further, a microprocessor (205) receives the slip signal and the articulation signal, controllably modifies the slip signal in response to the value of the articulation signal. The microprocessor (205) then compares the modified slip signal with a first predetermined reference value, and produces a braking control signal in response to the modified slip signal value exceeding the first predetermined reference value. Finally, one of the braking mechanisms (131, 133) receives the braking control signal and controllably applies the braking forces to the faster rotating wheel (101, 103) in response to the received signal.
On décrit un dispositif anti-patinage (100) destiné à un véhicule articulé doté d'au moins un essieu (118) comportant au moins deux roues motrices (101, 103). Ce dispositif anti-patinage (100) est muni de mécanismes de freinage (131, 133) qui appliquent des forces de freinage modulables à chacune des roues motrices. Un régisseur (160) produit un signal de dérapage dont la valeur correspond à la différence de vitesse de rotation enregistrée pour les roues (101, 103) de l'essieu (118). Un transducteur (165) produit un signal d'articulation dont la valeur correspond à l'angle d'articulation du véhicule. De plus, un microprocesseur (205) reçoit le signal de dérapage et le signal d'articulation et module le premier en fonction du second. Puis il compare le signal de dérapage modifié avec une première valeur de référence prédéterminée et produit un signal de contrôle de freinage en réponse à la valeur du signal de dérapage modifié lorsqu'elle dépasse la première valeur de référence prédéterminée. Enfin, l'un des mécanismes de freinage (131, 133) reçoit le signal de commande de freinage et applique en la modulant une force de freinage à la roue qui tourne le plus vite (101, 103) en réponse au signal reçu. |
