If the speed v102 of the preceding vehicle 102 increases, or the distance to this vehicle increases, although the hybrid vehicle 100 has maintained its speed, an acceleration process of the vehicle 102 can be concluded. It is therefore expected that the driver of the hybrid vehicle 100 will also soon accelerate to swim in the traffic flow. Therefore, it is not appropriate to switch off the engine 2, even if it makes sense for other reasons, since the internal combustion engine 2 for the

Abstract

L'invention concerne un procédé de commande d'un véhicule (100) doté d'un système d'entraînement hybride, comprenant au moins un moteur à combustion interne (2) et au moins une machine électrique (4). En vue d'obtenir une optimisation du comportement routier du véhicule (100), des paramètres de fonctionnement des véhicules sont détectés à partir de l'environnement du véhicule (100), au moyen d'un système de détection d'environnement (101). Le système d'entraînement hybride (1) est commandé en fonction des paramètres de fonctionnement détectés.
