Title (EN) METHOD FOR CALCULATING POSITIONS FOR SYNCHRONISING A DUAL-CLUTCH TRANSMISSION
(FR) PROCEDE DE CALCUL DE POSITIONS POUR LA SYNCHRONISATION D'UNE BOITE DE VITESSES A DOUBLE EMBRAYAGE
Abstract:
(EN) The invention relates to a method for calculating positions of specific points of synchroniser sleeves of a dual-clutch transmission driven by an engine for a vehicle, said transmission including two half-transmissions each controlled by one clutch, characterised in that, during a preparation phase for each gear engaged in a half-transmission, it applies a set engine torque curve comprising different fixed torque levels, and it engages gears of the other half-transmission during said levels, measuring and memorising positions of specific points (120, 122, 124) of the synchroniser sleeves during said engagements, and then, during driving phases of the vehicle, it calculates forecast positions for the specific points (120, 122, 124) by comparison with the memorised positions of the specific points (120, 122, 124) during similar driving conditions.
(FR) L'invention porte sur un procédé de calcul des positions de points particuliers de manchons de synchronisation d'une boîte de vitesses à double embrayage entraînée par un moteur pour un véhicule, cette boîte comportant deux demi-boîtes commandées chacune par un embrayage, caractérisé en ce que dans une phase de préparation pour chaque rapport de vitesse engagé d'une demi-boîte, il applique une courbe de consigne de couple moteur comprenant différents paliers de couples fixes, et il engage pendant ces paliers des rapports de l'autre demi-boîte, en mesurant et en mémorisant des positions de points particuliers (120, 122, 124) des manchons de synchronisation pendant ces engagements, ensuite lors des phases de roulage du véhicule il calcule pour les points particuliers (120, 122, 124) des positions prévisionnelles par comparaison avec les positions mémorisées des points particuliers (120, 122, 124) pendant des conditions de roulage similaires.
