Description

deux culasses (9).two cylinder heads (9).

La présente invention est relative à un dispositif de traction du type " hybride parallèle" notamment pour véhicule automobile, c'est-à-dire au moyen duquel les puissances mécaniques d'un moteur thermique et d'une machine électrique peuvent  The present invention relates to a traction device of the "parallel hybrid" type, in particular for a motor vehicle, that is to say by means of which the mechanical powers of a heat engine and an electric machine can

être combinées pour obtenir la puissance désirée à la roue.  be combined to obtain the desired power at the wheel.

On connait du brevet français n 2 787 395 déposé par la Demanderesse un dispositif de ce type comprenant: - une chaine de traction mécanique comportant un moteur thermique pouvant mettre en rotation un vi lebrequ in, un système de transmission comportant au moins un arbre de transmission primaire pouvant étre couplé mécaniquement audit vilebrequin et au moins un arbre de transmission secondaire en relation d'entranement avec au moins une roue dudit véhicule et pouvant étre couplé mécaniquement audit arbre de transmission primaire, - une machine électrique comportant un stator et un rotor, pouvant fonctionner sélectivement en moteur ou en générateur, led it rotor pouvant étre sélectivement s couplé mécaniquement audit arbre de transmission primaire ou audit arbre de  We know from French patent n 2 787 395 filed by the Applicant a device of this type comprising: - a mechanical traction chain comprising a heat engine which can rotate a vi lebrequ in, a transmission system comprising at least one transmission shaft primary which can be mechanically coupled to said crankshaft and at least one secondary transmission shaft in drive relation with at least one wheel of said vehicle and which can be mechanically coupled to said primary transmission shaft, - an electric machine comprising a stator and a rotor, which can selectively operate as a motor or generator, the rotor led can be selectively mechanically coupled to said primary drive shaft or to said drive shaft

transmission secondaire.secondary transmission.

La possibilité de coupler mécaniquement le rotor à l'arbre de transmission primaire ou à l'arbre de transmission secondaire présente notamment les avantages suivants: - Utilisation d'une machine électrique de puissance relativement faible et peu encombrante; - Démarrage du moteur thermique et rechargement de moyens de stockage d'énergie électrique, au moyen de la machine électrique, sans être pénalisé par le rendement du système de transmission; - Maintien de la continuité de la traction lors d'un changement de vitesse, et donc suppression de la sensation de décélération à cet instant; - Possibilité de transmettre aux roues du véhicule de la puissance mécanique produite par la machine électrique, et réciproquement de récupérer l'énergie de  The possibility of mechanically coupling the rotor to the primary drive shaft or to the secondary drive shaft has the following advantages in particular: - Use of an electric machine of relatively small and space-saving power; - Starting the internal combustion engine and recharging electrical energy storage means, using the electric machine, without being penalized by the performance of the transmission system; - Maintaining the continuity of traction during a gear change, and therefore eliminating the feeling of deceleration at this time; - Possibility of transmitting to the vehicle wheels mechanical power produced by the electric machine, and vice versa to recover the energy of

freinage, sans étre pénalisé par le rendement du système de transmission.  braking, without being penalized by the performance of the transmission system.

so Dans ce dispositif, les moyens daccouplement de la machine électrique aux arbres de transmission primaire et secondaire comprennent un pignon entra né par ie rotor de la machine électrique et monté libre en rotation sur l'arbre de transmission primaire, un pignon en relation d'entrainement avec le premier et monté libre en rotation sur i'arbre de transmission secondaire, et des crabots, déplacés par des actionneurs, permettant de craboter sélectivement ces pignons sur leurs arbres respectifs. L'utilisation de crabots nécessite une synchronisation des vitesses de rotation d'un pignon et de l'arbre correspondant préalablement à leur accouplement. Ces  n / a In this device, the means for coupling the electric machine to the primary and secondary transmission shafts comprise a pinion entered by the rotor of the electric machine and mounted to rotate freely on the primary transmission shaft, a pinion in relation to drive with the first and mounted free in rotation on the secondary transmission shaft, and dogs, moved by actuators, making it possible to selectively clutch these pinions on their respective shafts. The use of clutch dogs requires synchronization of the speeds of rotation of a pinion and of the corresponding shaft prior to their coupling. These

moyens d'accouplement sont complexes et délicats à mettre en _uvre.  coupling means are complex and delicate to implement.

En outre, la transmission de puissance par le seul intermédiaire de pignons offre peu de souplesse, le rapport des vitesses et celui des couples du rotor et de l'arbre de transmission secondaire étant déterminés par les dimensions de ces pignons. Il est 1C ainsi possible que, dans certaines conditions de roulage, le point de fonctionnement (régime, couple) de la machine électrique ne soit pas optimal, ce qui dégrade le  In addition, the transmission of power by the sole intermediary of pinions offers little flexibility, the speed ratio and that of the torques of the rotor and of the secondary transmission shaft being determined by the dimensions of these pinions. It is therefore possible that, under certain driving conditions, the operating point (speed, torque) of the electric machine is not optimal, which degrades the

rendement énergétique du véhicule.  vehicle fuel efficiency.

Si le moteur thermique participe à la transmission de puissance aux roues, son régime et la vitesse de rotation de l'arbre de transmission secondaire sont liés selon un s rapport déterminé par le système de transmission. Si ce rapport n'est pas adapté aux conditions de roulage, le point de fonctionnement du moteur thermique peut également ne pas être optimal, ce qui dégrade le rendement énergétique du véhicule  If the heat engine participates in the transmission of power to the wheels, its speed and the speed of rotation of the secondary drive shaft are linked according to a ratio determined by the transmission system. If this ratio is not adapted to the driving conditions, the operating point of the heat engine may also not be optimal, which degrades the fuel efficiency of the vehicle.

L'inertie mécanique du moteur thermique MT applique un couple résistif à la couronne 22, et permet ainsi à la machine électrique ME de transmettre un couple moteur à l'arbre de transmission secondaire 9 par l'intermédiaire du planétaire 24, des satellites 26 et du portesatellites 28, en bénéficiant de la démultiplication du train épicycloidal 20. Réciproquement, dans la méme configuration, pendant le freinage du véhicule V, les roues 14 peuvent entrainer en rotation ie rotor 15, par l'intermédiaire de l'arbre de transmission secondaire 9, des premier et deuxième pignons et du train épicyclodal 20, et permettre ainsi un fonctionnement en générateur électrique de la  The mechanical inertia of the thermal engine MT applies a resistive torque to the crown 22, and thus allows the electric machine ME to transmit a driving torque to the secondary transmission shaft 9 via the sun gear 24, the satellites 26 and of the satellite doors 28, while benefiting from the reduction of the planetary gear train 20. Conversely, in the same configuration, during the braking of the vehicle V, the wheels 14 can drive in rotation ie the rotor 15, by means of the secondary transmission shaft 9, first and second pinions and planetary gear 20, and thus allow operation as an electric generator of the

machine électrique ME.ME electric machine.

Si le couple résisitif exercé par le moteur thermique MT est insuffisant, des moyens de blocage ou de freinage du vilebrequin 1, non représentés, peuvent être prévus. Le dispositif selon l'invention permet, dans la configuration du mode a tout i5 électrique " décrite ci-dessus, de démarrer le moteur thermique MT, en roulage et sans démarreur, de deux manières: - Augmentation du couple moteur de la machine électrique ME de manière à produire un << surcouple ". Ce surcouple moteur est transmis partiellement au porte satellites 28 et aux roues 14 et partiellement à la couronne 22 et au vilebrequin 1,  If the resistive torque exerted by the heat engine MT is insufficient, means for blocking or braking the crankshaft 1, not shown, can be provided. The device according to the invention makes it possible, in the configuration of the all electric i5 "mode described above, to start the heat engine MT, while driving and without starter, in two ways: - Increase in the engine torque of the electric machine ME so as to produce an "overtorque". This engine overtorque is partially transmitted to the planet carrier 28 and to the wheels 14 and partially to the crown 22 and to the crankshaft 1,

2 o ce qui met en rotation ce dernier et permet de démarrer le moteur thermique MT.  2 o which sets the latter in rotation and makes it possible to start the thermal engine MT.

- Patinage de l'embrayage 7 après engagement d'une vitesse. L'engagement de la vitesse permet à l'arbre de transmission secondaire 9, entrainé par la machine éiectrique ME, de mettre en rotation l'arbre de transmission primaire 5. Le patinage  - Slipping of clutch 7 after engagement of a gear. The engagement of the speed allows the secondary transmission shaft 9, driven by the electric machine ME, to rotate the primary transmission shaft 5. Slippage

met en rotation le vilebrequin 1 et permet de démarrer le moteur thermique MT.  rotates the crankshaft 1 and allows the MT heat engine to be started.

En mode de propuision hybride, la machine électrique ME peut fonctionner  In hybrid propulsion mode, the ME electric machine can operate

en moteur ou en générateur.as an engine or generator.

Conformément à la règle de conservation de l'énergie, la somme des puissances fournies au dispositif, par le moteur thermique MT et/ou la machine électrique, égale, aux pertes par frottement près, la somme des puissance fournies par  In accordance with the energy conservation rule, the sum of the powers supplied to the device by the heat engine MT and / or the electric machine, equal to the friction losses, the sum of the powers supplied by

so le dispositif, aux roues 14 et/ou à la machine électrique ME.  so the device, to the wheels 14 and / or to the electric machine ME.

Ainsi, si la machine électrique ME foncnne en moteur, la puissance qu'elle produit s'ajoute à celle produite par le moteur thermique MT, la puissance résultante étant essentiellement transmise aux roues 14 (mode "boost"). Ce mode convient particulièrement aux situations de forte demande de puissance pour la traction, par  Thus, if the electric machine ME operates as an engine, the power it produces is added to that produced by the heat engine MT, the resulting power being essentially transmitted to the wheels 14 ("boost" mode). This mode is particularly suitable for situations of high power demand for traction, for example

exemple en cas de dépassement d'un autre véhicule.  example when passing another vehicle.

Si la machine électrique ME fonctionne en générateur, elle absorbe une part de la puissance produite par le moteur thermique MT, la fraction restante de cette puissance étant essentiellement transmise aux roues 14. Lors des phases de freinage, les roues 14 fournissent de la puissance à l'arbre de transmission primaire et au porte-satellites 28. Cette puissance est répartie, par l 'intermédiaire du vi lebrequ in 1 et du train épicyclodal 20, entre le moteur thermique  If the electric machine ME operates as a generator, it absorbs part of the power produced by the heat engine MT, the remaining fraction of this power being essentially transmitted to the wheels 14. During the braking phases, the wheels 14 supply power to the primary transmission shaft and to the planet carrier 28. This power is distributed, via the vi lebrequ in 1 and the planetary gear 20, between the heat engine

MT (u frein moteur ") et la machine électrique ME fonctionnant en générateur.  MT (u engine brake ") and the ME electrical machine operating as a generator.

Le dispositif selon l'invention offre la possibilité de combiner les puissances produites par le moteur thermique MT et par la machine électrique ME au moyen de la bolte de vitesses 3 (mode " hybride via la bolte de vitesses ") ou au moyen du train  The device according to the invention offers the possibility of combining the powers produced by the heat engine MT and by the electric machine ME by means of the gearbox 3 ("hybrid via the gearbox" mode) or by means of the train

épicyclodal 20 (mode " hybride via le train épicyclodal ").  epicyclodal 20 ("hybrid via the epicyclodal train" mode).

Le mode " hybride via la bolte de vitesses " nécessite l'enclenchement d'une vitesse et l'activation de l'embrayage 7. Dans cette configuration, les vitesses de rotation des arbres primaire 5 et secondaire 9, et donc celles de la couronne 22 et du planétaire 24, sont déterminées par la vitesse du véhicule V et par le rapport de vitesses enclenché dans la bolte de vitesses 3. La vitesse du véhicule V imposant également la vitesse du porte-satellites 28, toutes les vitesses de rotation des éléments zo du train épicyclodal 20, du moteur thermique MT et de la machine électrique ME sont toujours proportionnelles, le rapport de proportionnalité dépendant du rapport de la  The "hybrid via the gearbox" mode requires the engagement of a gear and the activation of the clutch 7. In this configuration, the speeds of rotation of the primary 5 and secondary 9 shafts, and therefore those of the crown 22 and planetary 24, are determined by the speed of the vehicle V and by the gear ratio engaged in the gearbox 3. The speed of the vehicle V also imposes the speed of the planet carrier 28, all the rotational speeds of the elements zo of the planetary gear train 20, the heat engine MT and the electric machine ME are always proportional, the proportionality ratio depending on the ratio of the

vitesse enclenchée.gear engaged.

Si la vitesse enclenchée n'est pas adaptée aux conditions de roulage, par exemple parce que la quatrième vitesse est engagée alors que l'allure du véhicule est faible, les couples produits par le moteur thermique MT et par la machine électrique ME sont mal adaptés à leurs régimes respectifs. La consommation énergétique et la  If the gear engaged is not adapted to the driving conditions, for example because the fourth gear is engaged while the speed of the vehicle is low, the torques produced by the heat engine MT and by the electric machine ME are unsuitable to their respective regimes. Energy consumption and

pollution émise sont importantes.pollution emitted are significant.

Il convient donc, comme pour un véhicule thermique traditionnel, d'adapter  It is therefore appropriate, as for a traditional thermal vehicle, to adapt

la vitesse enclenchée aux conditions de roulage.  the speed set to the driving conditions.

o Dans le mode " hybride via la bo^'te de vitesses ", une partie de la puissance transmise aux roues 14 transite par la bolte de vitesses 3, ce qui permet de profiter de  o In the "hybrid via the gearbox" mode, part of the power transmitted to the wheels 14 passes through the gearbox 3, which makes it possible to take advantage of

la démultiplication du rapport de vitesses enclenché.  the reduction of the gear ratio engaged.

Le mode " hybride via la boite de vitesses " est particulièrement avantageux quand le véhicule roule à vive allure et que des grands rapports de vitesses sont utilisés. Quand des petits rapports sont utilisés, le mode " hybride via le train  The "hybrid via the gearbox" mode is particularly advantageous when the vehicle is traveling at high speed and large gear ratios are used. When small ratios are used, the "hybrid via train" mode

épicycloidal >> est préférable, comme on le verra ci-après.  epicycloidal >> is preferable, as will be seen below.

Le mode " hybride via le train épicyclo7dal >' s'obtient en désactivant l'embrayage 7 ou en mettant la bolte de vitesses 3 au point mort. Toute la puissance transitant entre les roues 14 d'une part et le moteur thermique MT et la machine électrique ME d'autre part est ainsi transférée par l'intermédiaire du train épicyclodal 20. Pour une vitesse des roues 14 donnée, donc du porte-satellites 28, les vitesses de la couronne 22 et du planétaire 24 sont liées l'une à l'autre, mais ne sont pas nécessairement proportionnelles. Elles peuvent évoluer de manière continue, même si  The mode "hybrid via the planetary gear train> 'is obtained by deactivating the clutch 7 or by putting the gearbox 3 in neutral. All the power passing between the wheels 14 on the one hand and the heat engine MT and the electric machine ME on the other hand is thus transferred via the planetary gear train 20. For a given speed of the wheels 14, therefore of the planet carrier 28, the speeds of the crown 22 and of the sun gear 24 are linked one to the other, but are not necessarily proportional. They can evolve continuously, even if

la vitesse des roues 14 reste constante.  the speed of the wheels 14 remains constant.

Pour transmettre une puissance donnée aux roues, il est donc non seulement possible de fixer les contributions respectives du moteur thermique MT et de la machine électrique ME, comme dans le mode hybride via la bo^'te de vitesses, mais aussi de déterminer avec une grande souplesse les couples fourni par le moteur  To transmit a given power to the wheels, it is therefore not only possible to fix the respective contributions of the heat engine MT and of the electric machine ME, as in the hybrid mode via the gearbox, but also to determine with a great flexibility the torques provided by the motor

thermique MT et fourni ou absorbé par la machine électrique ME.  thermal MT and supplied or absorbed by the ME electric machine.

Très avantageusement, il est ainsi possible de faire varier ces couples, et ainsi les couples transmis aux roues 14, de manière continue. Le mode " hybride via le train épicyclodal " est donc également appelé < mode en transmission continue ". Pour le conducteur du véhicule, le train épicycloidal 20 se comporte à la manière d'une bote de vitesses qui aurait une multitude de rapports croissants, infiniment proches, le changement de rapport étant imperceptible et n'exigeant aucune intervention de sa part.  Very advantageously, it is thus possible to vary these torques, and thus the torques transmitted to the wheels 14, continuously. The mode "hybrid via the planetary gear train" is therefore also called "continuous transmission mode". For the driver of the vehicle, the planetary gear train 20 behaves like a gearbox which would have a multitude of increasing ratios, infinitely close, the gear change being imperceptible and requiring no intervention on his part.

La transmission continue offre donc un confort accru au conducteur.  The continuous transmission therefore offers increased comfort to the driver.

Le superviseur 34 peut adapter le point de fonctionnement (régime, couple) du moteur thermique MT et de la machine électrique ME de manière à optimiser la gestion énergétique globale du véhicule et à limiter les émissions polluantes, ce qui est  The supervisor 34 can adapt the operating point (speed, torque) of the heat engine MT and of the electric machine ME so as to optimize the overall energy management of the vehicle and to limit polluting emissions, which is

so particulièrement avantageux pour les parcours urbains.  so particularly advantageous for urban routes.

Comme dans le mode hybride via la boite de vitesses, ia machine électrique  As in the hybrid mode via the gearbox, the electric machine

ME peut fonctionner en générateur ou en moteur.  ME can operate as a generator or a motor.

La plage de rapports de vitesses que permet le train épicyclodal 20 est cependant étroite. Le mode hybride via la bolte de vitesses reste donc indispensable  The range of speed ratios that the planetary gear 20 allows is however narrow. The hybrid mode via the gearbox therefore remains essential

pour disposer de rapports élevés.to have high ratios.

Pour passer du mode de roulage hybride via le train épicyclodal 20 au mode de roulage hybride via la boite de vitesses, le régime du moteur thermique MT est asservi au régime de l'arbre de transmission primaire 5 par un contrôle en régime de la  To switch from hybrid driving mode via the planetary gear train 20 to hybrid driving mode via the gearbox, the engine speed MT is controlled by the speed of the primary drive shaft 5 by a speed control of the

machine électrique ME. Après synchronisation, I'embrayage 7 est activé.  ME electric machine. After synchronization, clutch 7 is activated.

Le couple de la machine électrique ME peut alors être progressivement diminué afin d'augmenter la puissance transmise par le moteur thermique MT à travers  The torque of the electric machine ME can then be gradually reduced in order to increase the power transmitted by the heat engine MT through

la boite de vitesses 3.gearbox 3.

Le dispositif selon la présente invention permet avantageusement de supprimer l'effet de décélération occasionné par un passage de vitesses en maintenant l'arbre de transmission secondaire 2 sous couple, grâce à la puissance mécanique fournie par la machine électrique ME. Pour cela, le superviseur 34 gère simultanément s 1es couples du moteur thermique MT et de la machine électrique ME, de manière à transférer toute la puissance du moteur thermique MT à travers la couronne 22. Toute cette puissance est fournie à l'arbre de transmission secondaire 9 à travers le train épicycloidal 20. L'embrayage 7 peut alors être désactivé sans que le conducteur ne ressente de décélération du véhicule V. Le véhicule roule alors en mode <. hybride via  The device according to the present invention advantageously makes it possible to eliminate the deceleration effect caused by a gear change by maintaining the secondary drive shaft 2 under torque, thanks to the mechanical power supplied by the electric machine ME. For this, the supervisor 34 simultaneously manages the couples of the heat engine MT and of the electric machine ME, so as to transfer all the power of the heat engine MT through the crown 22.
