La présente invention se rapporte à un procédé de commande d'un dispositif de transmission à variation de vitesse d'un groupe motopropulseur, en particulier pour véhicule hybride.The present invention relates to a method for controlling a speed variation transmission device of a powertrain, in particular for a hybrid vehicle.

Elle concerne plus particulièrement un dispositif de transmission à variation de vitesse à trains épicycloïdaux coaxiaux.It relates more particularly to a speed variation transmission device with coaxial planetary gears.

Comme cela est déjà connu, un véhicule hybride comporte un groupe motopropulseur qui utilise, seul ou en combinaison, comme mode d'entraînement en traction/propulsion, un moteur thermique à combustion interne avec un dispositif de transmission à variation de vitesse, et/ou une machine motrice/réceptrice, comme une machine électrique rotative reliée à une source électrique, telle qu'une ou plusieurs batteries.As is already known, a hybrid vehicle comprises a powertrain which uses, alone or in combination, as a traction / propulsion drive mode, an internal combustion engine with a variable speed transmission device, and / or a motor / receiver machine, such as a rotary electric machine connected to an electric source, such as one or more batteries.

Cette combinaison a pour avantage d'optimiser les performances de ce véhicule, notamment en réduisant les émissions de polluants dans l'atmosphère et en diminuant la consommation en carburant.This combination has the advantage of optimizing the performance of this vehicle, in particular by reducing the emission of pollutants into the atmosphere and by reducing fuel consumption.

Ainsi, lorsque l'on souhaite déplacer le véhicule avec un couple important sur une grande plage de vitesses tout en limitant la génération de gaz d'échappement et de bruit, comme dans un site urbain, l'utilisation de la machine électrique est privilégiée pour entraîner en déplacement ce véhicule.Thus, when it is desired to move the vehicle with a high torque over a large speed range while limiting the generation of exhaust gases and noise, as in an urban site, the use of the electric machine is preferred for drive this vehicle.

Par contre, le moteur thermique est utilisé pour déplacer ce véhicule lors d'utilisations où une puissance d'entraînement élevée et une grande autonomie de fonctionnement sont demandées.On the other hand, the heat engine is used to move this vehicle during uses where high driving power and long operating autonomy are required.

Comme cela est déjà connu par la demande de brevet français N°2 955 165 du demandeur, un tel groupe motopropulseur de véhicule automobile comprend un moteur thermique avec un arbre relié à un dispositif de transmission à variation de vitesse comportant un train épicycloïdal avec un planétaire et une couronne reliés chacun à l'arbre du moteur thermique par un accouplement à commande contrôlée et à une partie fixe du groupe par un accouplement automatique unidirectionnel, et un porte-satellites transmettant la variation de vitesse à l'essieu moteur du véhicule par l'intermédiaire d'une voie de transmission.As is already known from French patent application No. 2,955,165 of the applicant, such a motor vehicle powertrain comprises a heat engine with a shaft connected to a speed variation transmission device comprising an epicyclic train with a planetary gear and a crown each connected to the engine shaft by a controlled coupling and to a fixed part of the group by a one-way automatic coupling, and a planet carrier transmitting the speed variation to the driving axle of the vehicle by l via a transmission channel.

De façon à augmenter la capacité de variation de vitesse lors de l'entraînement du véhicule par la machine électrique, le demandeur a associé, au dispositif de transmission à variation de vitesse du document précité, un autre train épicycloïdal reliant le train épicycloïdal de moteur à la voie de transmission de mouvement à l'essieu moteur de ce véhicule, comme cela est décrit dans la demande de brevet français N°2 962 697 du demandeur.In order to increase the speed variation capacity when the vehicle is driven by the electric machine, the applicant has associated, with the speed variation transmission device of the aforementioned document, another planetary gear train connecting the engine planetary gear train to the movement transmission path to the driving axle of this vehicle, as described in French patent application No. 2,962,697 to the applicant.

Bien que donnant satisfaction, le demandeur a encore amélioré ce dispositif de variation de vitesse en offrant la possibilité d'augmenter le nombre de rapport de vitesse grâce à un dispositif de transmission à variation de vitesse de conception simple et peu coûteuse tout en réduisant son encombrement et en assurant une commande simple et efficace de cette transmission.Although satisfactory, the applicant has further improved this speed variation device by offering the possibility of increasing the number of gear ratios by means of a speed variation transmission device of simple and inexpensive design while reducing its size. and ensuring simple and efficient control of this transmission.

A cet effet, l'invention concerne un procédé de commande d'un dispositif de transmission à variation de vitesse d'un groupe motopropulseur, en particulier pour véhicule hybride, comportant un moteur thermique, une machine motrice/réceptrice, un dispositif de variation de vitesse comprenant un train épicycloïdal de moteur avec un planétaire et une couronne reliés chacun à l'arbre de moteur par un accouplement à commande contrôlée et à une partie fixe du groupe par un accouplement automatique unidirectionnel et un porte-satellites, et un train épicycloïdal de machine placé concentriquement au train épicycloïdal de moteur et reliant le train épicycloïdal de moteur à une voie de transmission de mouvement vers un essieu moteur, ledit train épicycloïdal de machine comprenant un planétaire, une couronne et un porte satellites, caractérisé en ce qu'on bloque le planétaire avec la couronne du train épicycloïdal de machine pour assurer le déplacement du véhicule par la machine électrique seule ou en association avec le moteur).To this end, the invention relates to a method of controlling a device for transmitting a speed variation of a powertrain, in particular for a hybrid vehicle, comprising a heat engine, a driving / receiving machine, a device for varying the speed comprising an epicyclic engine train with a sun gear and a crown each connected to the engine shaft by a controlled coupling and to a fixed part of the group by a one-way automatic coupling and a planet carrier, and an epicyclic train of machine placed concentrically with the planetary engine train and connecting the planetary engine train to a movement transmission path to a driving axle, said planetary machine train comprising a planet gear, a crown and a planet carrier, characterized in that one blocks the sun gear with the crown of the planetary gear train to move the vehicle p by the electric machine alone or in combination with the motor).

On peut placer un accouplement à commande contrôlée entre la couronne et le planétaire.A controlled coupling can be placed between the crown and the sun gear.

On peut placer un accouplement à commande contrôlée sur l'arbre qui porte la couronne du train épicycloïdal de machine.A controlled coupling can be placed on the shaft which carries the crown of the planetary gear train.

Les autres caractéristiques et avantages de l'invention vont apparaître maintenant à la lecture de la description qui va suivre, donnée à titre uniquement illustratif et non limitatif, et à laquelle est annexée la figure unique qui est un schéma montrant un dispositif de transmission à variation de vitesse d'un groupe motopropulseur selon l'invention.The other characteristics and advantages of the invention will now appear on reading the description which follows, given by way of illustration only and not limiting, and to which is appended the single figure which is a diagram showing a transmission device with variation speed of a powertrain according to the invention.

Sur la figure unique, le groupe motopropulseur comprend un moteur thermique 10, notamment un moteur à combustion interne, avec un arbre moteur 12, ici issu du vilebrequin de ce moteur, un dispositif de variation de vitesse 14 et un essieu moteur 16 qui permet d'entraîner les roues motrices 18 du véhicule, avantageusement par l'intermédiaire d'un pont différentiel 20.In the single figure, the powertrain comprises a heat engine 10, in particular an internal combustion engine, with an engine shaft 12, here coming from the crankshaft of this engine, a speed variation device 14 and a drive axle 16 which allows driving the driving wheels 18 of the vehicle, advantageously by means of a differential bridge 20.

Le groupe motopropulseur comprend également une machine électrique 22 avec un rotor 24, qui peut fonctionner en tant que moteur électrique d'entraînement pour le véhicule ou en tant que générateur d'énergie électrique et plus particulièrement en tant qu'alternateur pour assurer la charge des batteries (non représentées).The powertrain also includes an electric machine 22 with a rotor 24, which can function as an electric drive motor for the vehicle or as an electric power generator and more particularly as an alternator for ensuring the charge of batteries (not shown).

Le dispositif de variation de vitesse 14 comprend un train épicycloïdal principal 26, baptisé train épicycloïdal de moteur thermique, avec deux embrayages à commande contrôlée 28, 30 et deux accouplements unidirectionnels automatiques, comme des roues libres 32, 34.The speed variation device 14 comprises a main planetary gear 26, called an epicyclic train of a heat engine, with two controlled clutches 28, 30 and two automatic one-way couplings, such as freewheels 32, 34.

Plus précisément, le train épicycloïdal de moteur 26 comprend un planétaire denté extérieurement 36 et monté fixement sur un arbre creux 38, dit arbre de planétaire, venant coiffer l'arbre 12 du moteur en étant libre en rotation mais fixe en translation par rapport à celui-ci. L'extrémité libre de cet arbre creux se continue par un arbre plein 40 qui prend appui dans un palier 42 porté par une partie fixe 44 du groupe motopropulseur du véhicule, comme le carter, au travers de l'accouplement unidirectionnel 32, baptisé roue libre planétaire.More specifically, the planetary gear train 26 includes an externally toothed sun gear 36 and fixedly mounted on a hollow shaft 38, called a sun gear shaft, coming to cover the shaft 12 of the motor while being free in rotation but fixed in translation relative to that -this. The free end of this hollow shaft is continued by a solid shaft 40 which is supported in a bearing 42 carried by a fixed part 44 of the powertrain of the vehicle, like the casing, through the one-way coupling 32, called free wheel planetary.

Ce train comprend également une couronne dentée 46 placée concentriquement au planétaire et reliée à un arbre creux 48, dit arbre de couronne, venant entourer l'arbre creux 38 du planétaire tout en étant libre en rotation mais fixe en translation par rapport à celui-ci. Cette couronne est reliée extérieurement à la partie fixe 44 du groupe motopropulseur du véhicule par l'accouplement unidirectionnel 34, baptisé roue libre couronne.This train also includes a toothed crown 46 placed concentrically with the sun gear and connected to a hollow shaft 48, called the crown shaft, which surrounds the hollow shaft 38 of the sun gear while being free in rotation but fixed in translation relative to the latter. . This crown is externally connected to the fixed part 44 of the vehicle's powertrain by the one-way coupling 34, known as the crown freewheel.

Bien entendu, les deux roues libres 32 et 34 sont placées de manière telle que la couronne et le planétaire ne puissent tourner que dans le même sens et préférentiellement dans le même sens que l'arbre 12 du moteur.Of course, the two freewheels 32 and 34 are placed in such a way that the crown and the sun gear can only rotate in the same direction and preferably in the same direction as the shaft 12 of the engine.

Enfin, ce train épicycloïdal de moteur comprend un porte-satellites 50 avec avantageusement trois satellites 52, en forme de roue à denture extérieure, placés dans un même intervalle angulaire l'un par rapport à l'autre (ici à 120°) et engrenant avec la couronne et le planétaire.Finally, this planetary gear train comprises a planet carrier 50 with advantageously three satellites 52, in the form of an external gear wheel, placed in the same angular interval relative to each other (here at 120 °) and meshing with the crown and the planetary.

Pour cela, la couronne, le planétaire et les satellites sont situés dans un même plan, ici dans un plan vertical en considérant la figure.For this, the crown, the planet and the satellites are located in the same plane, here in a vertical plane considering the figure.

Ces satellites sont portés par une paroi verticale 54 reliée à un arbre tubulaire 56, dit arbre de porte-satellites, qui vient entourer l'arbre plein de planétaire 40 en étant libre en rotation sur celui-ci.These satellites are carried by a vertical wall 54 connected to a tubular shaft 56, called the planet carrier shaft, which comes to surround the solid sun gear shaft 40 while being free to rotate thereon.

Les extrémités libres des arbres du planétaire et de la couronne portent chacune un accouplement à commande contrôlée 28 et 30, de préférence un embrayage à friction, commandé par un actionneur de débrayage 58, 60, ici sous la forme d'un levier basculant sur un point fixe du groupe motopropulseur entre une position embrayée (Position N) et une position débrayée (Position 1).The free ends of the sun shafts and of the crown each carry a controlled coupling 28 and 30, preferably a friction clutch, controlled by a declutch actuator 58, 60, here in the form of a lever rocking on a fixed point of the powertrain between a engaged position (Position N) and a disengaged position (Position 1).

Comme mieux illustré sur la figure, la paroi verticale 54 du porte-satellites 50 se poursuit sur sa périphérie par un bandeau horizontal 62 denté intérieurement qui est porté par l'arbre de porte-satellites 56. Ce bandeau forme la couronne d'un autre train épicycloïdal additionnel 64, dénommé dans la suite de la description train épicycloïdal de machine électrique.As best illustrated in the figure, the vertical wall 54 of the planet carrier 50 continues on its periphery by a horizontal strip 62 internally toothed which is carried by the planet carrier shaft 56. This strip forms the crown of another additional planetary gear train 64, called in the following description the planetary gear train of an electric machine.

Ce train épicycloïdal de machine 64 est placé coaxialement au train épicycloïdal de moteur thermique 26 en entourant l'arbre plein de planétaire 40. Ce train comprend aussi un porte-satellites 66 avec avantageusement trois satellites 68, en forme de roue à denture extérieure, engrenant avec la denture de la couronne 62.This planetary gear train 64 is placed coaxially with the planetary engine train 26 by surrounding the solid sun gear shaft 40. This train also includes a planet carrier 66 with advantageously three satellites 68, in the form of an external gear wheel, meshing with the teeth of the crown 62.

Ces satellites coopèrent également à engrènement avec un planétaire 70 monté fixement sur un arbre tubulaire 72, dit arbre de planétaire additionnel, qui vient entourer, librement en rotation mais fixement en translation, l'arbre de porte-satellites 56 qui est aussi l'arbre de la couronne 62. L'extrémité libre de l'arbre tubulaire 72 porte fixement une roue dentée 74 qui coopère avec une autre roue dentée 76 portée fixement par le rotor 24 de la machine électrique 22.These satellites also cooperate in engagement with a sun gear 70 fixedly mounted on a tubular shaft 72, called an additional sun gear shaft, which surrounds, freely rotating but fixedly in translation, the planet carrier shaft 56 which is also the shaft of the crown 62. The free end of the tubular shaft 72 fixedly carries a toothed wheel 74 which cooperates with another toothed wheel 76 fixedly carried by the rotor 24 of the electric machine 22.

Bien entendu, comme pour le train épicycloïdal de moteur thermique 26, la couronne 62, les satellites 68 et le planétaire 70 sont situés dans un même plan, ici dans un plan vertical en considérant la figure unique.Of course, as for the planetary gear train of the heat engine 26, the crown 62, the satellites 68 and the sun gear 70 are located in the same plane, here in a vertical plane considering the single figure.

Les axes des satellites 68 sont portés par un plateau vertical 78 relié à un arbre tubulaire de porte-satellites 80 entourant librement en rotation mais fixement en translation l'arbre tubulaire de planétaire 72.The axes of the satellites 68 are carried by a vertical plate 78 connected to a tubular shaft of planet carrier 80 freely surrounding in rotation but fixedly in translation the tubular planetary shaft 72.

Cet arbre tubulaire de porte-satellites 80 porte fixement une roue dentée 82 qui coopère avec une roue dentée 84 liée à l'essieu moteur 16. Cet ensemble des deux roues dentées forme ainsi une voie de transmission de mouvement entre le train épicycloïdal de machine 64 et l'essieu 16.This tubular planet carrier shaft 80 fixedly carries a toothed wheel 82 which cooperates with a toothed wheel 84 linked to the drive axle 16. This set of two toothed wheels thus forms a path for transmitting movement between the planetary gear train 64 and axle 16.

Le train épicycloïdal de machine 64 comprend également un accouplement à commande contrôlée 86 permettant de relier sa couronne 62, soit à l'arbre de planétaire 72 avec le planétaire 70 et la roue dentée 74, soit à la partie fixe 44 du groupe motopropulseur.The planetary gear train 64 also includes a controlled coupling 86 making it possible to connect its crown 62, either to the sun gear shaft 72 with the sun gear 70 and the toothed wheel 74, or to the fixed part 44 of the powertrain.

De manière avantageuse, cet accouplement est placé sur l'extrémité libre de l'arbre de porte-satellites 56.Advantageously, this coupling is placed on the free end of the planet carrier shaft 56.

A titre uniquement d'exemple, cet accouplement comprend un synchroniseur avec deux positions d'engrènement (1, 2) et une position neutre (N). Ce synchroniseur est porté fixement en rotation par l'arbre de porte-satellites 56 tout en étant mobile en translation axiale sur celle-ci. Ce synchroniseur est prévu pour coopérer, soit avec la partie fixe 44 du groupe motopropulseur (position 1), soit avec l'arbre de planétaire 72 avec la roue dentée de planétaire 74 (position 2), soit être en position neutre sans être en liaison avec aucun de ces deux éléments. Pour cela, le synchroniseur est soumis à un moyen de commande 88 lui permettant de réaliser sa translation axiale.As an example only, this coupling comprises a synchronizer with two engagement positions (1, 2) and a neutral position (N). This synchronizer is fixedly rotated by the planet carrier shaft 56 while being movable in axial translation thereon. This synchronizer is designed to cooperate, either with the fixed part 44 of the powertrain (position 1), or with the sun gear shaft 72 with the planetary gear wheel 74 (position 2), or be in neutral position without being connected with neither of these two elements. For this, the synchronizer is subjected to a control means 88 allowing it to perform its axial translation.

Le fonctionnement de cette transmission, permet de réaliser les rapports, comme cela est indiqué dans le tableau ci-dessous.The operation of this transmission allows reports to be made, as indicated in the table below.

Actionneur Actuator Rapport Report 28 28 30 30 Position Position 1 1 1 1 0 0 N NOT 1 1 1 1 1 1 N NOT 2 2 N NOT N NOT 3 3

Le tableau ci-dessus, sans l’état de l’actionneur, 86 définit le moyen d’obtenir les 3 rapports entre le moteur thermique et le train épicycloïdal de machine 64. Pour obtenir ces 3 rapports, le train 26, les deux roues libres 32 et 34, ainsi que les d’accouplement 28 et 30 sont utilisés. Les 3 rapports découlent de la combinaison des états des accouplements 28 et 30 comme décrit dans le tableau ci-dessus.The table above, without the state of the actuator, 86 defines the means of obtaining the 3 ratios between the thermal engine and the planetary gear train of machine 64. To obtain these 3 ratios, the train 26, the two wheels free 32 and 34, as well as coupling 28 and 30 are used. The 3 reports result from the combination of the states of the couplings 28 and 30 as described in the table above.

L'accouplement à trois positions 86 sert au changement de mode.The three-position coupling 86 is used for mode change.

Lorsque l’accouplement 88 est en position 1, la couronne du train 64 et le porte satellites du train épicycloïdal 26 sont bloqués au carter. Ce mode correspond au mode électrique pur sur un premier rapport. Dans ce cas, la machine peut être utilisée en mode motrice ou en mode génératrice.When the coupling 88 is in position 1, the crown of the train 64 and the planet carrier of the planetary gear 26 are locked to the casing. This mode corresponds to the pure electric mode on a first gear. In this case, the machine can be used in drive mode or in generator mode.

Lorsque l'accouplement 88 est en position 2, le planétaire 70 et la couronne 62 du train épicycloïdal 64 sont couplés, tous les arbres du train 64 ont le même régime. Dans ce mode, il est possible, soit d’utiliser la transmission en mode électrique pur sur un second rapport électrique en mode motrice, soit d’utiliser le moteur thermique seul sur un des 3 rapports, soit d’utiliser le groupe motopropulseur en mode hybride parallèle avec un des 3 rapports (3 modes hybride parallèle).When the coupling 88 is in position 2, the sun gear 70 and the ring gear 62 of the planetary gear 64 are coupled, all the shafts of the gear 64 have the same speed. In this mode, it is possible either to use the transmission in pure electric mode on a second electric report in drive mode, or to use the heat engine alone on one of the 3 reports, or to use the powertrain in mode parallel hybrid with one of the 3 reports (3 parallel hybrid modes).

La position centrale (position neutre) de l’actionneur 88, permet d’accéder aux modes e-CVT. Le mode e-CVT est accessible avec chacun des rapports décrits dans le tableau ci-dessus. Ce qui revient à disposer de 3 modes e-CVT.The central position (neutral position) of the actuator 88 allows access to the e-CVT modes. The e-CVT mode is accessible with each of the reports described in the table above. This amounts to having 3 e-CVT modes.

Les avantages procurés par le blocage de la couronne et du planétaire de train 64, résident principalement dans la réalisation de la solution. En effet, cette disposition permet une conception plus compacte et simplifie les contraintes de guidages des arbres du train 64.The advantages provided by the blocking of the crown and of the planetary gear 64, mainly reside in the realization of the solution. Indeed, this arrangement allows a more compact design and simplifies the constraints of guiding the shafts of train 64.
