Abstract

Le procédé comprend les étapes de a) déterminer un couple minimum (CPAVmin) délivrable par un groupe motopropulseur thermique de train avant ; b) comparer le couple minimum à une consigne optimale (CVC_AV) du groupe motopropulseur thermique et respectant une répartition optimale de couple ; c) dans le cas où le couple minimum est supérieur à la consigne optimale et n’excède par un seuil haut (SVC_AV), affecter le couple minimum à une première consigne effective (CCAV) du groupe motopropulseur thermique et déterminer une deuxième consigne (CCAR) d’un groupe motopropulseur électrique de train arrière qui autorise un maintien d’une consigne de couple total (CVC) voulue par le conducteur; et d) dans le cas où le couple minimum est supérieur à la consigne optimale et excède le seuil haut, affecter le couple minimum à la première consigne et déterminer la deuxième consigne de façon à respecter la répartition optimale. Fig.2The method comprises the steps of a) determining a minimum torque (CPAVmin) deliverable by a front axle thermal powertrain; b) compare the minimum torque to an optimal setpoint (CVC_AV) of the thermal powertrain and respecting optimal torque distribution; c) in the case where the minimum torque is greater than the optimal setpoint and does not exceed a high threshold (SVC_AV), assign the minimum torque to a first effective setpoint (CCAV) of the thermal powertrain and determine a second setpoint (CCAR ) an electric rear axle powertrain which allows maintenance of a total torque setting (CVC) desired by the driver; and d) in the case where the minimum torque is greater than the optimal setpoint and exceeds the high threshold, assign the minimum torque to the first setpoint and determine the second setpoint so as to respect the optimal distribution.
