Abstract
(EN)
A management method of a hybrid drive assembly for vehicles, in particular scooters, comprising at least one engine (3) and an electric machine (32). The method comprises the phases of operating the engine that it does not provide torque and operating the electric machine that it functions as generator for charging an accumulator (36) when the torque requested is negative. Operating the engine and/or the electric machine to satisfy the required torque, and/or bring the accumulator to a pre-established charge level and/or run the engine under maximum efficiency regime conditions, when the torque required is positive and lower than the maximum torque which can be supplied by the internal combustion engine; and operating the internal combustion engine and/ or the electric machine with the supply of a propulsive torque so as to satisfy the torque required, when the desired torque is positive and higher than the maximum torque which can be supplied by the engine. Furthermore, when requested by the pilot and in accordance with the charge level of the batteries (36), the control method switches off the engine and drives the electric machine only to supply the torque requested.

L'invention concerne un procédé de gestion du mode de fonctionnement d'un ensemble de propulsion hybride pour des véhicules, en particulier des scooters, ainsi qu'un ensemble de propulsion hybride utilisant ce procédé, cet ensemble de propulsion hybride comprenant au moins un moteur à combustion interne et un moteur électrique. Le procédé selon l'invention consiste à déterminer un couple requis et un état du véhicule d'après un ensemble de commandes et/ou de paramètres d'entrée reçus et se caractérise en ce qu'il consiste à commander le moteur à combustion interne de sorte qu'il ne fournisse pas de couple et à commander le moteur électrique de sorte qu'il fonctionne comme un générateur pour charger un accumulateur, lorsque le couple requis est négatif; à commander le moteur à combustion interne et/ou le moteur électrique de façon à obtenir le couple requis et/ou amener l'accumulateur à un niveau de charge préétabli et/ou faire fonctionner le moteur à combustion interne dans des conditions de régime à efficacité maximale, lorsque le couple requis est positif et inférieur au couple maximum pouvant être fourni par le moteur à combustion interne; et à commander le moteur à combustion interne et/ou le moteur électrique avec fourniture d'un couple de propulsion de façon à obtenir le couple requis, lorsque le couple requis est positif et supérieur au couple maximum pouvant être fourni par le moteur à combustion interne. En outre, en cas de demande du conducteur et en fonction du niveau de charge des batteries, le procédé de commande arrête le moteur à combustion interne et commande uniquement le moteur électrique pour fournir le couple requis.
