Abstract

L'invention porte principalement sur un procédé de pilotage d'un moteur thermique de véhicule automobile (1), caractérisé en ce que, pour suivre un profil de vitesse (P_cy) définissant une pluralité de vitesses de consigne en fonction du temps, ledit procédé comporte les étapes suivantes: - une étape de modélisation d'un retard d'exécution d'un couple (tr) lié à une capacité du moteur thermique à fournir un couple, - une étape de calcul d'une accélération (a) permettant d'atteindre une vitesse cible, ladite accélération tenant compte du retard d'exécution du couple (tr), - une étape de calcul d'un couple appliqué par des roues motrices pour obtenir l'accélération (a) préalablement calculée, - une étape de détermination d'un couple moteur (Cm) correspondant, et - une étape d'activation d'un organe de commande (P) du véhicule pour obtenir le couple moteur précédemment déterminé.The invention relates mainly to a method for controlling a heat engine of a motor vehicle (1), characterized in that, to follow a speed profile (P_cy) defining a plurality of set speeds as a function of time, said method includes the following steps: - a step of modeling a delay in the execution of a torque (tr) linked to a capacity of the heat engine to provide a torque, - a step of calculating an acceleration (a) allowing d '' reach a target speed, said acceleration taking into account the torque execution delay (tr), - a step of calculating a torque applied by driving wheels to obtain the previously calculated acceleration (a), - a step of determination of a corresponding engine torque (Cm), and - a step of activating a control member (P) of the vehicle to obtain the engine torque previously determined.
