Abstract

The internal combustion engine (1) drives an electrical coupling machine (3) rotor (5) and the satellite carriers (15) of an epicylic gear train (11). The rotor /stator (7) of the electrical machine is connected to the epicyclic planet (13) and the epicyclic crown is connected to the road wheels (19). Two other connection architectures are available and a supervisor directs energy flow to/from batteries and wheels as driving conditions require

On se réfère à présent à la figure 5 du dessin annexé, sur laquelle on a représenté un mode de réalisation du dispositif selon l'invention conforme à l'architecture c) susmentionnée.  Referring now to Figure 5 of the accompanying drawing, which shows an embodiment of the device according to the invention according to the architecture c) above.

La stratégie de commande du superviseur s'appuie sur la connaissance de divers paramètres, notamment : - la demande de couple moteur formulée par le conducteur du véhicule, telle que cette demande est traduite par l'enfoncement d'une pédale d'accélérateur, - l'intensité du freinage, telle qu'elle est traduite par l'enfoncement d'une pédale de freinage, - l'état des batteries (état décharge, puissance, tension, température), connu par l'intensité qu'elles délivrent et par leur capacité, - la vitesse de rotation du moteur thermique 1, et - les vitesses de rotation des différents organes constitutifs du train épicycloïdal 11.  The supervisor's control strategy is based on the knowledge of various parameters, in particular: the demand for engine torque formulated by the driver of the vehicle, such that this request is translated by the depression of an accelerator pedal; the braking intensity, as reflected by the depression of a brake pedal, - the state of the batteries (state of discharge, power, voltage, temperature), known by the intensity they deliver and by their capacity, the speed of rotation of the heat engine 1, and the speeds of rotation of the various constituent members of the epicyclic gear train 11.

La stratégie de commande du superviseur peut donner lieu aux modes de fonctionnement suivants, décrits en référence aux figures 6 à 17 sur lesquelles on a  The control strategy of the supervisor can give rise to the following operating modes, described with reference to FIGS. 6 to 17, on which

<Desc/Clms Page number 5><Desc / Clms Page number 5>

représenté les flux d'énergie en cause dans le cas d'un mode de réalisation du dispositif selon l'invention conforme à la figure 1.  represented the energy flows involved in the case of an embodiment of the device according to the invention according to Figure 1.

Mode traction tout électrique
Dans ce mode de fonctionnement, le moteur thermique 1 est arrêté, et le rotor/stator 7 fournit au planétaire 13 l'énergie nécessaire au déplacement du véhicule, et transmet en tournant une énergie magnétique au rotor 5. All-electric traction mode
In this mode of operation, the heat engine 1 is stopped, and the rotor / stator 7 supplies the sun gear 13 with the energy necessary for the displacement of the vehicle, and transmits by turning a magnetic energy to the rotor 5.

Cette énergie magnétique est transformée en énergie mécanique fournie au porte-satellites 15 pour garantir la stabilité du train épicycloïdal 11.  This magnetic energy is converted into mechanical energy supplied to the planet carrier 15 to guarantee the stability of the epicyclic gear train 11.

Le rotor 5 récupère (figure 6) au fournit (figure 7) de l'énergie électrique, selon que l'énergie magnétique susmentionnée est inférieure ou non à l'énergie mécanique nécessaire pour assurer la stabilité du train épicycloïdal 11.  The rotor 5 recovers (FIG. 6) from the supply (FIG. 7) of the electrical energy, depending on whether the aforementioned magnetic energy is less than the mechanical energy necessary to ensure the stability of the epicyclic gear train 11.

Mode traction hybride
Dans ce mode de fonctionnement, le moteur thermique 1 est en marche et fournit de l'énergie mécanique qui est utilisée pour entraîner la roue 19 du véhicule via le porte-satellites 15 et éventuellement pour recharger les batteries. Hybrid traction mode
In this operating mode, the heat engine 1 is running and provides mechanical energy that is used to drive the wheel 19 of the vehicle via the planet carrier 15 and possibly to recharge the batteries.

Les batteries peuvent aussi fournir de l'énergie par l'intermédiaire du coupleur 3 : on parle alors de mode hybride avec boost électrique.  The batteries can also supply energy via the coupler 3: this is called hybrid mode with electric boost.

Le tableau suivant récapitule les quatre configurations possibles du mode hybride, en fonction des entrées et sorties en couple (C) et en vitesse (N) du coupleur 3 :

The following table summarizes the four possible configurations of the hybrid mode, according to the inputs and outputs in torque (C) and speed (N) of the coupler 3:

En phase de démarrage du moteur thermique 1, la puissance fournie par ce moteur peut être inférieure à celle demandée au porte-satellites 15. In the starting phase of the heat engine 1, the power supplied by this engine may be less than that requested at the planet carrier 15.

<Desc/Clms Page number 6> <Desc / Clms Page number 6>

C'est le cas dans les configurations représentées aux figures 12 et 13, dans lesquelles le coupleur 3 doit fournir de l'énergie à la fois au porte-satellites 15 et au planétaire 13 : c'est une phase de boost électrique.  This is the case in the configurations shown in Figures 12 and 13, in which the coupler 3 must supply energy to both the planet carrier 15 and the sun gear 13: it is an electric boost phase.

La configuration représentée à la figure 13 se différencie de celle représentée à la figure 12 en ceci qu'elle comprend une boucle de recirculation d'énergie électromagnétique.  The configuration shown in FIG. 13 differs from that shown in FIG. 12 in that it comprises an electromagnetic energy recirculation loop.

Mode freinage récupérai
Le véhicule passe dans ce mode de fonctionnement dès qu'on lâche la pédale d'accélérateur. Braking mode recovered
The vehicle goes into this mode of operation as soon as you release the accelerator pedal.

Une partie de l'énergie mécanique disponible à la roue 19 est réinjectée sous forme électrique dans les batteries.  Part of the mechanical energy available to the wheel 19 is reinjected into electrical form in the batteries.

Le moteur thermique 1 est alors amené à son régime minimal, s'il est démarré.  The engine 1 is then brought to its minimum speed, if it is started.

Les figures 14 à 17 représentent différentes configurations de freinage récupératif : en mode hybride (figure 14), avec recirculation magnétique (figure 15), en mode tout électrique (figure 16), et en mode tout électrique avec recirculation magnétique (figure 17).  FIGS. 14 to 17 show different regenerative braking configurations: in hybrid mode (FIG. 14), with magnetic recirculation (FIG. 15), in all-electric mode (FIG. 16), and in all-electric mode with magnetic recirculation (FIG. 17).

Le choix d'un mode de réalisation parmi ceux qui ont été décrits plus haut pourra être fait en fonction d'un cahier des charges spécifiant différentes contraintes à respecter : coût, encombrement, etc.  The choice of an embodiment among those described above may be made according to a specification specifying different constraints to be respected: cost, size, etc.

On notera en effet par exemple que les modes de réalisation dans lesquels le coupleur 3 est coaxial avec le moteur thermique 1 et le train épicycloïdal 11 (voir figures 1 et 3) sont particulièrement compacts, et peuvent donc convenir pour des véhicules dans lesquels il y a peu de place disponible pour le groupe motopropulseur.  It will be noted for example that the embodiments in which the coupler 3 is coaxial with the heat engine 1 and the epicyclic gear train 11 (see FIGS. 1 and 3) are particularly compact, and may therefore be suitable for vehicles in which there is has little space available for the powertrain.

Bien entendu, la présente invention n'est pas limitée au mode de réalisation décrit et représenté, fourni à titre d'exemple illustratif et non limitatif. Of course, the present invention is not limited to the embodiment described and shown, provided by way of illustrative and non-limiting example.
