Description

La présente invention se rapporte à un groupe motopropulseur pour véhicule automobile de type hybride. The present invention relates to a powertrain for a hybrid-type motor vehicle.

Ce type de véhicule comporte un groupe motopropulseur qui utilise un moteur thermique à combustion interne avec un dispositif de variation de vitesse et/ou une machine électrique rotative reliée à une source électrique, telle qu'un ou plusieurs accumulateurs électriques. This type of vehicle comprises a powertrain which uses an internal combustion engine with a speed variation device and / or a rotary electric machine connected to an electrical source, such as one or more electric accumulators.

Une telle utilisation a pour avantage d'optimiser les performances de ce 10 véhicule, à réduire les émissions de polluants dans l'atmosphère et à diminuer la consommation en carburant du groupe motopropulseur dans sa globalité. Such use has the advantage of optimizing the performance of this vehicle, reducing emissions of pollutants into the atmosphere and reducing the fuel consumption of the entire powertrain.

Ainsi et comme cela est généralement connu, lorsque l'on souhaite déplacer le véhicule avec un couple important sur une grande plage de vitesses 15 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. Par contre, le moteur thermique est utilisé pour déplacer ce véhicule lors d'utilisations où une puissance d'entraînement élevée et une grande autonomie 20 de fonctionnement sont demandées. Thus and as is generally known, when it is desired to move the vehicle with a large torque over a wide range of speeds while limiting the generation of exhaust and noise, as in an urban site, the use of the electric machine is preferred to drive this vehicle on the move. On the other hand, the heat engine is used to move this vehicle in applications where high drive power and high operating autonomy are required.

Dans l'exemple décrit dans le document FR 2 931 399, un groupe motopropulseur comprend un moteur thermique et une machine électrique avec un rotor relié à la couronne d'un pont différentiel. Ce pont est généralement 25 utilisé pour l'entraînement d'un essieu moteur qui porte les roues de ce véhicule. Cette machine électrique est reliée à la couronne du pont au travers d'un étage de réduction qui permet de délivrer un couple important pour le démarrage de ce véhicule (ou décollage), ainsi que pour de basses vitesses de 30 déplacement de ce véhicule. In the example described in document FR 2 931 399, a powertrain comprises a heat engine and an electric machine with a rotor connected to the crown of a differential bridge. This bridge is generally used for driving a drive axle which carries the wheels of this vehicle. This electric machine is connected to the crown of the bridge through a reduction stage which allows to deliver a significant torque for the starting of this vehicle (or takeoff), as well as for low speeds of displacement of this vehicle.

Ceci nécessite donc d'utiliser une machine électrique de grande capacité et d'encombrement important, ce qui ne peut que grever le coût de revient d'un tel groupe motopropulseur. De plus, lors du déplacement du véhicule par le moteur thermique et dans le cas où la vitesse du véhicule est telle que le régime de la machine électrique peut dépasser son régime maximal, cette machine électrique doit être déconnectée de la couronne. Ceci permet d'éviter que le rotor de cette machine ne subisse un emballement en rotation pouvant entraîner sa détérioration lors du déplacement à grandes vitesses du véhicule. This therefore requires the use of an electric machine of large capacity and large size, which can only burden the cost of such a powertrain. In addition, during the movement of the vehicle by the engine and in the case where the speed of the vehicle is such that the speed of the electric machine can exceed its maximum speed, this electrical machine must be disconnected from the crown. This prevents the rotor of this machine from experiencing a rotational runaway that can cause its deterioration when moving at high speeds of the vehicle.

En outre, ce document ne décrit qu'un seul étage de réduction et un choix doit être fait entre les performances du véhicule pour son décollage ou pour ses vitesses élevées, sauf à surdimensionner la machine électrique pour pouvoir réaliser les deux fonctions. In addition, this document describes only one reduction stage and a choice must be made between the performance of the vehicle for takeoff or for high speeds, except oversize the electric machine to perform both functions.

La présente invention se propose de remédier aux inconvénients ci-dessus avec un groupe motopropulseur dont la machine électrique peut être utilisée sur toute la plage de fonctionnement du véhicule et avec une puissance de cette machine électrique moins grande. The present invention proposes to overcome the above drawbacks with a powertrain whose electric machine can be used throughout the range of operation of the vehicle and with a power of this smaller electric machine.

A cet effet, l'invention concerne un groupe motopropulseur de véhicule automobile à entraînement hybride comprenant un moteur thermique, une boîte de vitesses reliée au moteur au travers d'un accouplement débrayable, une machine électrique avec un rotor relié à un pont différentiel d'entrainement d'un essieu moteur au travers d'un dispositif de transmission, caractérisé en ce que le dispositif de transmission comprend au moins deux voies alternatives de transmission de mouvement entre le rotor de la machine électrique et le pont différentiel. To this end, the invention relates to a powertrain of a hybrid drive motor vehicle comprising a heat engine, a gearbox connected to the engine through a disengageable coupling, an electric machine with a rotor connected to a differential bridge. driving a driving axle through a transmission device, characterized in that the transmission device comprises at least two alternative channels of motion transmission between the rotor of the electric machine and the differential bridge.

Le dispositif de transmission peut comprendre un arbre moteur relié à la 30 machine électrique par un train d'engrenage et un arbre récepteur relié au pont différentiel. The transmission device may comprise a motor shaft connected to the electrical machine by a gear train and a receiver shaft connected to the differential bridge.

Le dispositif de transmission peut comprendre au moins deux roues dentées fixes portées par l'un des arbres et qui coopèrent chacune avec une roue dentée montée folle sur l'autre des arbres. The transmission device may comprise at least two stationary gear wheels carried by one of the shafts and which each cooperate with a toothed wheel mounted idle on the other of the shafts.

Les voies de transmission de mouvement peuvent comprendre chacune une roue dentée fixe engrenant avec une roue dentée montée folle. The motion transmission channels may each comprise a stationary gear meshing with an idle gear.

Le dispositif de transmission peut comprendre au moins un accouplement débrayable pour solidariser en rotation l'une ou l'autre des roues dentées folles avec l'arbre qui les portent. The transmission device may comprise at least one disengageable coupling for locking in rotation one or the other of the idler gear wheels with the shaft carrying them.

Le dispositif transmission de vitesse peut comprendre un accouplement à glissement contrôlé pour solidariser en rotation l'une ou l'autre des roues dentées folles avec l'arbre qui les portent. L'accouplement à glissement contrôlé est un embrayage multidisques dans l'huile. The speed transmission device may comprise a controlled slip coupling for rotating one or the other of the idler gearwheels to the shaft carrying them. The controlled slip coupling is a multi-plate clutch in the oil.

Les autres caractéristiques et avantages de l'invention vont apparaître à la 20 lecture de la description qui va suivre, donnée à titre uniquement illustratif et non limitatif, et à laquelle est annexée la figure unique qui montre une vue schématique du groupe motopropulseur selon l'invention. The other features and advantages of the invention will become apparent on reading the following description, given solely by way of illustration and not limitation, and to which is appended the single figure which shows a schematic view of the powertrain according to the invention. invention.

Le groupe motopropulseur 10 pour un véhicule à entraînement hybride 25 illustré sur la figure unique comprend un moteur thermique à combustion interne 12, une boîte de vitesses 14 et une machine électrique 16. Le moteur thermique 12 est un moteur de type Essence mais tout autre type de moteur thermique, qu'il soit à injection directe ou indirecte de carburant, peut être utilisé, comme un moteur de type Diesel ou ceux fonctionnant à 30 l'essence, au Gaz Naturel pour Véhicules (GNV),...15 La boîte de vitesses 14, qui est ici à titre d'exemple une boîte de vitesses robotisée, comprend un carter de boîte 18 logeant un arbre primaire 20 et un arbre secondaire 22 disposés sensiblement parallèles l'un à l'autre. L'arbre primaire est relié au vilebrequin 24 du moteur thermique au travers d'un accouplement débrayable 26 dont l'ouverture et la fermeture sont contrôlées par un actionneur (non représenté), de préférence électromagnétique. L'arbre primaire porte une multiplicité de roues dentées fixes 28 qui engrènent avec des pignons fous 30 portés par l'arbre secondaire. L'arbre secondaire porte également des baladeurs translatifs 32 qui permettent de solidariser les pignons fous avec cet arbre. L'arbre secondaire porte aussi un pignon fixe 34, ici en bout d'arbre, qui coopère avec un pont différentiel 36 et plus particulièrement avec la couronne 38 de ce pont. The power train 10 for a hybrid drive vehicle 25 shown in the single figure comprises an internal combustion engine 12, a gearbox 14 and an electric machine 16. The engine 12 is a gasoline type engine but any other type of a heat engine, whether direct or indirect fuel injection, can be used, such as a diesel type engine or those running on gasoline, natural gas for vehicles (CNG), ... 15 The box 14, which is here by way of example a robotized gearbox, comprises a box housing 18 housing a primary shaft 20 and a secondary shaft 22 arranged substantially parallel to each other. The primary shaft is connected to the crankshaft 24 of the heat engine through a disengageable coupling 26 whose opening and closing are controlled by an actuator (not shown), preferably electromagnetic. The primary shaft carries a multiplicity of stationary gear wheels 28 which mesh with idle gears 30 carried by the secondary shaft. The secondary shaft also carries translational players 32 which make it possible to secure the idle gears with this shaft. The secondary shaft also carries a fixed gear 34, here at the end of the shaft, which cooperates with a differential bridge 36 and more particularly with the crown 38 of this bridge.

Un essieu moteur 40 est relié à ce pont différentiel pour entraîner les roues du véhicule (non représentées). A driving axle 40 is connected to this differential bridge to drive the wheels of the vehicle (not shown).

La machine électrique 16 comprend un rotor 42 et est reliée électriquement à des accumulateurs électriques ou batteries (non représentés). The electric machine 16 comprises a rotor 42 and is electrically connected to electric accumulators or batteries (not shown).

Cette machine fonctionne en tant que moteur électrique d'entraînement pour le véhicule ou en tant que générateur d'énergie électrique pour assurer la charge des batteries et/ou l'alimentation des différentes parties électriques du véhicule, comme ses accessoires. This machine functions as an electric drive motor for the vehicle or as an electric power generator to ensure the charging of the batteries and / or the power supply of the various electrical parts of the vehicle, such as its accessories.

De façon à pouvoir raccorder cinématiquement la machine électrique à l'essieu moteur 40 ou au moteur thermique 12 ou aux deux à la fois, le rotor 42 de cette machine est relié par un dispositif de transmission 44 à la couronne 38 du pont différentiel 36 sans pour cela nécessiter des modifications importantes tant au niveau de la boîte de vitesse qu'à celui du pont différentiel.30 Ce dispositif de transmission comprend ici deux voies alternatives débrayables de transmission de mouvement de rotation entre le rotor 42 de la machine électrique et le pont différentiel 36. In order to be able to kinematically connect the electric machine to the driving axle 40 or to the heat engine 12 or to both at the same time, the rotor 42 of this machine is connected by a transmission device 44 to the ring gear 38 of the differential bridge 36 without for this to require significant changes both in the gearbox and that of the differential bridge.30 This transmission device here comprises two alternative ways of disengageable transmission of rotational movement between the rotor 42 of the electric machine and the bridge differential 36.

Plus précisément, le dispositif comprend une cascade de roues dentées, ici trois roues dentées 46, 48, 50, partant du rotor 42 de la machine 16 et arrivant à une roue dentée fixe 52 portée par un arbre, dit arbre moteur 54. Les roues dentées 46, 48, 50 et 52 forment ainsi un train d'engrenage moteur. More specifically, the device comprises a cascade of gears, here three gears 46, 48, 50, starting from the rotor 42 of the machine 16 and arriving at a fixed gear 52 carried by a shaft, said drive shaft 54. The wheels teeth 46, 48, 50 and 52 thus form a gear motor.

10 Cet arbre moteur porte également deux roues dentées fixes 56, 58 à distance l'une de l'autre qui coopèrent chacune avec une roue dentée 60, 62 montée folle sur un arbre récepteur 64 sensiblement parallèle à l'arbre moteur. Cet arbre récepteur comprend aussi une roue dentée fixe 66 qui coopère à engrènement avec la couronne 38 du pont différentiel. 15 Ce dispositif de transmission comprend ainsi deux voies alternatives débrayables avec deux étages de réduction (ou deux rapports de vitesses) différents, l'une formée par la roue fixe 56 et la roue folle 60 et l'autre formée par la roue fixe 58 et la roue folle 62. 20 De manière à pouvoir activer l'un ou l'autre (ou aucun) de ces étages de réduction, le dispositif de transmission comprend un accouplement débrayable 68, ici à engagement positif. A titre d'exemple, cet accouplement est un actionneur à griffes 70 coopérant avec des ouvertures 72 prévues sur les voiles 25 des roues dentées 60 et 62. Pour cela, cet actionneur est un baladeur translatif sur l'arbre récepteur 64 mais fixe en rotation sur cet arbre (avec des dispositifs de crabots et de synchros) et qui est commandé en translation par tous moyens connus, tel qu'un vérin électromagnétique 74. Ce baladeur permet ainsi, soit de solidariser l'une ou l'autre des roues folles 60 ou 62 avec cet arbre (position 1 30 ou 2), soit de laisser libre en rotation les deux roues folles (position N). This drive shaft also carries two fixed gears 56, 58 spaced apart from each other which each cooperate with a toothed wheel 60, 62 mounted idle on a receiving shaft 64 substantially parallel to the drive shaft. This receiver shaft also comprises a stationary gear 66 which cooperates meshing with the crown 38 of the differential bridge. This transmission device thus comprises two disengageable alternative paths with two different reduction stages (or two gear ratios), one formed by the fixed wheel 56 and the idle wheel 60 and the other formed by the fixed wheel 58 and the idler wheel 62. In order to activate either (or none) of these reduction stages, the transmission device comprises a disengageable coupling 68, here positive engagement. By way of example, this coupling is a claw actuator 70 cooperating with openings 72 provided on the webs 25 of the toothed wheels 60 and 62. For this, this actuator is a translative sliding device on the receiving shaft 64 but is fixed in rotation. on this shaft (with jaw and synchro devices) and which is controlled in translation by any known means, such as an electromagnetic cylinder 74. This player thus allows either to secure one or the other of the idlers 60 or 62 with this shaft (position 1 30 or 2), or to leave free in rotation the two idlers (position N).

Bien entendu, il est à la portée de l'homme du métier de prévoir les caractéristiques (dimensions, nombre de dents, ...) des différentes roues dentées 46 à 52, 56 et 60, 58 et 62 pour obtenir le rapport de vitesse souhaité entre le rotor 42 et l'arbre récepteur 64. De même, la cascade de roues dentées 46, 48, 50 et 52 peut être remplacée par tout autre élément assurant la transmission de mouvement de rotation entre le rotor 42 et l'arbre moteur 54, comme une courroie crantée. Of course, it is within the abilities of those skilled in the art to provide the characteristics (dimensions, number of teeth, ...) of the different gears 46 to 52, 56 and 60, 58 and 62 to obtain the gear ratio. desired between the rotor 42 and the receiver shaft 64. Similarly, the gear cascade 46, 48, 50 and 52 can be replaced by any other element ensuring the transmission of rotational movement between the rotor 42 and the motor shaft 54, as a toothed belt.

10 Avantageusement, le dispositif de transmission 44 est logé dans un boîtier fermé 76 qui porte des paliers 78 pour les arbres 54 et 64. Ces paliers permettent ainsi d'éviter d'induire des efforts parasites sur le rotor de la machine électrique. Le boîtier 76 de la transmission 44 est rapporté sur le pont différentiel 36 15 en étant fixé à celui-ci par tous moyens connus, comme par vissage, de telle sorte que la roue dentée 66 de l'arbre récepteur 64 coopère à engrènement avec la couronne 38 au travers d'une ouverture 80 pratiquée dans le carter de ce pont. Advantageously, the transmission device 44 is housed in a closed housing 76 which carries bearings 78 for the shafts 54 and 64. These bearings thus make it possible to avoid inducing parasitic forces on the rotor of the electric machine. The housing 76 of the transmission 44 is attached to the differential bridge 36 by being fixed thereto by any known means, such as by screwing, so that the toothed wheel 66 of the receiving shaft 64 co-meshes with the crown 38 through an opening 80 made in the housing of this bridge.

20 Ainsi, cette machine électrique avec son dispositif de transmission raccordé au pont différentiel permet de pouvoir réaliser l'entraînement du véhicule sur toute sa plage de fonctionnement grâce aux deux rapports de vitesses. De plus, le dimensionnement du premier rapport permet de décoller le 25 véhicule en mode électrique sur de fortes pentes, telles que celles des parkings souterrains. En outre, la présence d'un dispositif de transmission avec deux rapports améliore le rendement de fonctionnement de la machine électrique. Thus, this electric machine with its transmission device connected to the differential bridge makes it possible to drive the vehicle over its entire operating range thanks to the two gear ratios. In addition, the sizing of the first gear makes it possible to take off the vehicle in electric mode on steep slopes, such as those of the underground car parks. In addition, the presence of a two-speed transmission device improves the operating efficiency of the electric machine.

30 Sans sortir du cadre de l'invention, il peut être envisagé de remplacer l'actionneur à griffes 68 par tout autre moyen équivalent, comme un5 accouplement à glissement contrôlé, tel qu'un embrayage multidisques à bain d'huile. A titre d'exemple non limitatif, cet embrayage contient deux jeux de disques ou lamelles, le premier étant lié au côté "machine électrique", l'autre 5 côté "roues" (ou pont différentiel). Un moyen à ressort maintient cet embrayage fermé en mettant en contact les jeux de disques entre eux de façon à assurer la liaison entre le côté "machine électrique" et le cotés "roues". Pour pouvoir ouvrir cet embrayage, une pression hydraulique est appliquée à l'encontre du moyen à ressort pour 10 pouvoir desserrer les disques. L'avantage de cette variante est de permettre le changement de rapport sous charge, de manière à minimiser la rupture de couple à la roue et ce au bénéfice de l'agrément de conduite. Ce groupe motopropulseur permet ainsi d'entraîner le véhicule en mode 15 thermique par le moteur 12, en mode électrique par la machine 16 au travers de son dispositif de transmission 44, ou en mode assistance électrique (plus connu sous le terme de "Boost Electrique"). Il permet également de faire fonctionner le groupe motopropulseur en mode démarrage électrique, ou en mode récupération d'énergie. 20 Pour le mode thermique d'entrainement du véhicule, le moteur thermique 12 est en fonctionnement, l'accouplement débrayable 26 est fermé en assurant la liaison entre le vilebrequin 24 et la boîte de vitesse 14. Le véhicule se déplace donc sous l'impulsion de l'essieu moteur 40 via le pont différentiel 36 et 25 selon le rapport de vitesse enclenché de la boîte de vitesse. Le rotor 42 de la machine électrique 16 peut être entrainé en rotation par l'intermédiaire de la couronne 38 et du dispositif de transmission 44 en fonction de la position d'enclenchement de l'actionneur 68 (position 1 ou 2). Par cela, la machine électrique est utilisée en tant que génératrice 30 électrique pour alimenter les différentes parties électriques du véhicule et/ou pour assurer la recharge des batteries auxquelles elle est reliée. Without departing from the scope of the invention, it may be envisaged to replace the claw actuator 68 by any other equivalent means, such as a controlled slip coupling, such as an oil bath multi-disk clutch. By way of nonlimiting example, this clutch contains two sets of disks or slats, the first being linked to the "electrical machine" side, the other to the "wheels" side (or differential bridge). A spring means maintains this clutch closed by contacting the sets of disks together so as to ensure the connection between the "electric machine" side and the "wheels" side. In order to open this clutch, hydraulic pressure is applied against the spring means to loosen the discs. The advantage of this variant is to allow the gear shift under load, so as to minimize the breaking of torque to the wheel and the benefit of driving pleasure. This powertrain thus enables the vehicle to be driven in thermal mode by the engine 12, in electrical mode by the machine 16 through its transmission device 44, or in electrical assistance mode (better known as "Electric Boost" "). It also makes it possible to operate the powertrain in electric starting mode, or in energy recovery mode. For the thermal drive mode of the vehicle, the heat engine 12 is in operation, the disengageable coupling 26 is closed by ensuring the connection between the crankshaft 24 and the gearbox 14. The vehicle is therefore moving under the impulse. of the drive axle 40 via the differential bridge 36 and 25 according to the speed gear engaged gearbox. The rotor 42 of the electric machine 16 can be rotated through the ring gear 38 and the transmission device 44 depending on the engagement position of the actuator 68 (position 1 or 2). By this, the electric machine is used as an electric generator to power the various electrical parts of the vehicle and / or to recharge the batteries to which it is connected.

Dans le mode d'entraînement électrique, le moteur thermique 12 ne fonctionne pas, l'accouplement débrayable 26 est en position ouverte et la machine électrique 16 est alimentée électriquement en devenant ainsi un moteur électrique d'entraînement pour le véhicule. In the electric drive mode, the heat engine 12 does not operate, the disengageable coupling 26 is in the open position and the electric machine 16 is electrically powered thereby becoming an electric drive motor for the vehicle.

Le couple de ce moteur électrique est ainsi transmis aux roues dentées 46, 48, 50 et 52 pour aboutir à l'arbre moteur 54. En fonction de la position d'enclenchement de l'actionneur à griffes 68, il est possible d'obtenir deux régimes de vitesses différents sur la couronne 38 et par conséquent à l'essieu moteur 40 en combinant la vitesse de rotation du rotor 42 avec l'un ou l'autre des rapports du dispositif de transmission 44. The torque of this electric motor is thus transmitted to the gears 46, 48, 50 and 52 to reach the drive shaft 54. Depending on the engagement position of the claw actuator 68, it is possible to obtain two different speeds of speeds on the ring gear 38 and consequently on the driving axle 40 by combining the speed of rotation of the rotor 42 with one or other of the ratios of the transmission device 44.

Dans la position 1 de cet actionneur, il est obtenu un premier étage de réduction sur l'arbre récepteur par l'engrènement de la roue dentée fixe 56 de l'arbre moteur 54 avec la roue dentée 60 rendue solidaire en rotation avec l'arbre 64 par l'actionneur 68. Ce rapport de vitesse entre le moteur électrique et l'arbre récepteur est ensuite transmis par la roue dentée fixe 66 de l'arbre récepteur à la couronne 38 du pont différentiel. Dans la position alternative 2 de l'actionneur 68, un deuxième étage de réduction est réalisé par engrènement de la roue dentée fixe 58 avec la roue dentée 62 solidarisée à l'arbre récepteur par cet actionneur. De même, cet autre rapport de vitesse entre le moteur électrique et l'arbre récepteur est transmis par la roue dentée fixe 66 de l'arbre récepteur au pont différentiel 36. In the position 1 of this actuator, a first reduction stage is obtained on the receiving shaft by meshing of the fixed gear wheel 56 of the drive shaft 54 with the gear wheel 60 made integral in rotation with the shaft 64 by the actuator 68. This speed ratio between the electric motor and the receiving shaft is then transmitted by the fixed gear 66 of the receiving shaft to the ring 38 of the differential bridge. In the alternative position 2 of the actuator 68, a second reduction stage is formed by meshing of the stationary gear 58 with the gearwheel 62 secured to the output shaft by this actuator. Likewise, this other speed ratio between the electric motor and the receiver shaft is transmitted by the fixed gear 66 of the receiving shaft to the differential bridge 36.

Dans la position N de l'actionneur 68, le rotor 42 ne transmet pas de 25 couple aux roues et n'est pas entraîné en rotation. Ce mode est avantageusement engagé lorsque seul le moteur thermique 12 est utilisé. In the position N of the actuator 68, the rotor 42 does not transmit torque to the wheels and is not rotated. This mode is advantageously engaged when only the heat engine 12 is used.

Bien entendu, toutes les autres configurations d'utilisation de la machine électrique sont possibles comme décrits ci-après à titre d'exemple. 30 Pour le mode assistance électrique ("Boost Electrique"), le moteur thermique 12 fonctionne, l'accouplement débrayable 26 est en position de fermeture et la machine électrique 16 est alimentée pour agir en tant que moteur électrique. Le moteur électrique apporte ainsi un couple supplémentaire à celui du moteur thermique, couple dont la valeur dépendra du rapport de réduction (position 1 ou 2 de l'actionneur). Of course, all other configurations of use of the electric machine are possible as described hereinafter by way of example. For electric boost mode, the heat engine 12 operates, the disengageable coupling 26 is in the closed position and the electric machine 16 is energized to act as an electric motor. The electric motor thus provides additional torque to that of the engine, torque whose value depends on the reduction ratio (position 1 or 2 of the actuator).

Pour assurer le démarrage électrique du moteur thermique lorsque le véhicule est en déplacement sous l'effet de la machine électrique, l'accouplement débrayable 26 est en position de fermeture, un rapport de vitesse de la boîte est enclenché et un étage de réduction du dispositif de transmission est actif. Le moteur électrique fournit ainsi le couple nécessaire au démarrage du moteur thermique 12 au travers du dispositif de transmission 44, du pont 36 et de la boîte de vitesses 14. Ceci permet de passer du mode électrique au mode thermique sans à-coups pendant le déplacement du véhicule, ce qui améliore le confort de conduite. To ensure the electric start of the engine when the vehicle is in motion under the effect of the electric machine, the disengageable coupling 26 is in the closed position, a speed ratio of the box is engaged and a reduction stage of the device transmission is active. The electric motor thus provides the necessary torque for starting the heat engine 12 through the transmission device 44, the bridge 36 and the gearbox 14. This makes it possible to switch from electric mode to thermal mode smoothly during the displacement of the vehicle, which improves driving comfort.

Dans les phases de décélération ou de freinage du véhicule, la machine électrique 16 permet de récupérer une grande partie de l'énergie dégagée lors de ces phases. Le couple de décélération ou de freinage sur les roues du véhicule est 20 transmis au pont 36 puis au rotor 42 de cette machine par le dispositif de transmission 44 où l'un des étages de réduction est opérationnel. La machine électrique est donc transformée en génératrice électrique qui permet de recharger les accumulateurs électriques et/ou d'alimenter les différentes parties électriques du véhicule dans toutes les phases de 25 décélération du véhicule. In the deceleration or braking phases of the vehicle, the electric machine 16 makes it possible to recover a large part of the energy released during these phases. The deceleration or braking torque on the vehicle wheels is transmitted to the bridge 36 and then to the rotor 42 of this machine by the transmission device 44 where one of the reduction stages is operational. The electric machine is thus transformed into an electric generator that recharges the electric accumulators and / or power the various electrical parts of the vehicle in all phases of deceleration of the vehicle.
