Title
(EN) METHOD AND DEVICE FOR CONTROLLING THE PLACING IN THE SLIPPING STATE OF A CLUTCH OF A VEHICLE WITH ROBOTIC GEARBOX
(FR) PROCÉDÉ ET DISPOSITIF DE CONTRÔLE DU PLACEMENT DANS L'ÉTAT DE GLISSEMENT D'UN EMBRAYAGE D'UN VÉHICULE À BOÎTE DE VITESSES ROBOTISÉE
Abstract
(EN)
A control method is implemented in a vehicle comprising a heat engine providing the torque on a crankshaft to which an engine flywheel is rigidly attached, a robotic gearbox comprising a primary shaft and a secondary shaft providing N forward gear ratios, where N > 2, a clutch coupling the primary shaft to the engine flywheel and that can be placed in the slipping state, and a first mapping defining N first primary zones associated respectively with the N ratios, each first primary zone being delimited by primary delimitations defined by operating points. This method comprises a step (10-20) in which the placing of the clutch in a slipping state is imposed when the current operating point is in at least a first secondary zone contiguous with a predefined first primary zone.
(FR)
Un procédé de contrôle est mis en oeuvre dans un véhicule comprenant un moteur thermique fournissant du couple sur un vilebrequin auquel est solidarisé un volant moteur, une boîte de vitesses robotisée et comprenant un arbre primaire et un arbre secondaire offrant N rapports de marche avant, avec N > 2, un embrayage couplant l'arbre primaire au volant moteur et plaçable dans un état de glissement, et une première cartographie définissant N premières zones primaires associées respectivement aux N rapports, chaque première zone primaire étant délimitée par des délimitations primaires définies par des points de fonctionnement. Ce procédé comprend une étape (10-20) dans laquelle on impose le placement de l'embrayage dans un état de glissement lorsque le point de fonctionnement en cours est compris dans au moins une première zone secondaire contigüe d'une première zone primaire prédéfinie.
