Description
ARCHITECTURE DE TRACTION AMÉLIORÉE DE TYPE HYBRIDE BASSE TENSION POUR VÉHICULE AUTOMOBILEIMPROVED LOW VOLTAGE HYBRID TYPE TRACTION ARCHITECTURE FOR MOTOR VEHICLE
La présente invention porte sur une architecture de traction améliorée de type hybride basse tension pour véhicule automobile.The present invention relates to an improved traction architecture of the low-voltage hybrid type for a motor vehicle.
De façon connue en soi, une chaîne de traction de véhicule automobile comporte un moteur thermique accouplé à une boîte de vitesses par l'intermédiaire d'un embrayage. La boîte de vitesses est reliée mécaniquement aux roues par l'intermédiaire d'un différentiel.In a manner known per se, a motor vehicle traction chain comprises a heat engine coupled to a gearbox by means of a clutch. The gearbox is mechanically connected to the wheels via a differential.
Une machine électrique réversible est accouplée au moteur thermique via la façade accessoires. Cette machine électrique, appelée communément alterno-démarreur, est apte à fonctionner dans un mode générateur pour recharger une batterie du véhicule ainsi que dans un mode moteur pour assurer un démarrage du moteur thermique. Cette machine électrique pourra également être utilisée pour fournir de l'énergie à la batterie lors d'une phase de freinage récupératif.A reversible electric machine is coupled to the heat engine via the accessories front. This electric machine, commonly called alternator-starter, is capable of operating in a generator mode for recharging a vehicle battery as well as in an engine mode for ensuring a starting of the thermal engine. This electric machine can also be used to supply energy to the battery during a regenerative braking phase.
Il est connu également d'utiliser une autre machine électrique réversible accouplée à la boîte de vitesses. Cette machine électrique est apte à fonctionner en mode moteur pour assurer une traction du véhicule seule ou en combinaison avec le moteur thermique. Cette machine est également apte à fonctionner en mode générateur pour fournir de l'énergie à la batterie du véhicule.It is also known to use another reversible electric machine coupled to the gearbox. This electric machine is capable of operating in engine mode to provide traction for the vehicle alone or in combination with the heat engine. This machine is also able to operate in generator mode to supply energy to the vehicle battery.
Ces machines électriques sont généralement des machines de forte puissance, de l'ordre de 50kW, connectées sur un réseau électrique présentant une tension de fonctionnement de 300 Volts.These electrical machines are generally high-power machines, of the order of 50 kW, connected to an electrical network having an operating voltage of 300 volts.
Il a été observé qu'avec ce type d'architecture les émissions de dioxyde de carbone et autres particules polluantes sont élevées sur les grandes distances de roulage. En effet, sur ces distances, les conditions de roulage sont telles que le véhicule fonctionne le plus souvent en mode thermique. Or, le poids des batteries alimentant le réseau haute tension étant important, le moteur thermique consomme beaucoup de carburant pour assurer seul la traction du véhicule, ce qui engendre une émission importante de dioxyde de carbone et autres particules polluantes.It has been observed that with this type of architecture, emissions of carbon dioxide and other polluting particles are high over long driving distances. Indeed, over these distances, the driving conditions are such that the vehicle most often operates in thermal mode. However, the weight of the batteries supplying the high voltage network being significant, the heat engine consumes a lot of fuel to ensure only the traction of the vehicle, which generates a significant emission of carbon dioxide and other polluting particles.
En outre, malgré les formations techniques reçues par les opérateurs pour réparer des pannes électriques, il existe un risque sécuritaire d'électrocution compte tenu des tensions élevées utilisées pour alimenter les machines électriques de traction.In addition, despite the technical training received by operators to repair electrical failures, there is a risk of electric shock given the high voltages used to power electric traction machines.
La présente invention vise à remédier efficacement à ces inconvénients en proposant une architecture de traction pour véhicule automobile comportant:The present invention aims to effectively remedy these drawbacks by proposing a traction architecture for a motor vehicle comprising:
- un moteur thermique,- a heat engine,
- une boîte de vitesses ayant un arbre d'entrée et un arbre de sortie,- a gearbox having an input shaft and an output shaft,
- un embrayage interposé entre le moteur thermique et l'arbre d'entrée de la boîte de vitesses, caractérisée en ce que ladite architecture de traction comporte en outre une machine électrique tournante de type réversible, ladite machine électrique tournante étant accouplée avec l'arbre de sortie de la boîte de vitesses,- a clutch interposed between the heat engine and the input shaft of the gearbox, characterized in that said traction architecture further comprises a rotary electrical machine of reversible type, said rotary electrical machine being coupled with the shaft gearbox output,
- la machine électrique tournante étant connectée à un réseau électrique présentant une tension de fonctionnement inférieure à 60Volts.- the rotating electrical machine being connected to an electrical network having an operating voltage of less than 60Volts.
L'invention permet ainsi, grâce à l'utilisation d'un réseau électrique inférieur à 60 Volts, d'embarquer des batteries moins lourdes que sur un réseau haute tension classique, ce qui permet de minimiser les émissions de particules polluantes sur les grandes distances lorsque le véhicule fonctionne dans un mode de roulage thermique. L'invention permet en outre de réduire le coût de l'architecture de traction du fait de la taille réduite des machines électriques tournantes. L'invention permet en outre de supprimer le risque sécuritaire, dans la mesure où les tensions mises en œuvre ne sont pas susceptibles de causer une électrocution à l'opérateur intervenant sur le véhicule automobile.The invention thus makes it possible, thanks to the use of an electrical network less than 60 Volts, to carry on lighter batteries than on a conventional high voltage network, which makes it possible to minimize the emissions of polluting particles over long distances. when the vehicle is operating in a thermal driving mode. The invention also makes it possible to reduce the cost of the traction architecture due to the reduced size of the rotating electrical machines. The invention also makes it possible to eliminate the security risk, insofar as the voltages used are not likely to cause electrocution to the operator working on the motor vehicle.
Selon une réalisation, la tension de fonctionnement du réseau électrique est de 48 Volts.According to one embodiment, the operating voltage of the electrical network is 48 Volts.
Selon une réalisation, la machine électrique tournante est montée de façon coaxiale avec l'arbre de sortie de la boîte de vitesses.According to one embodiment, the rotary electric machine is mounted coaxially with the output shaft of the gearbox.
Selon une réalisation, la machine électrique tournante est montée parallèlement à l'arbre de sortie de la boîte de vitesses.According to one embodiment, the rotary electric machine is mounted parallel to the output shaft of the gearbox.
Selon une réalisation, la machine électrique tournante est reliée mécaniquement à l'arbre de sortie par l'intermédiaire d'un dispositif de transmission de mouvement.According to one embodiment, the rotary electric machine is mechanically connected to the output shaft by means of a movement transmission device.
Selon une réalisation, la machine électrique tournante est montée à l'intérieur de la boîte de vitesses.According to one embodiment, the rotary electric machine is mounted inside the gearbox.

Les figures 1a et 1b montrent une architecture de traction 10 pour véhicule 20 automobile comportant une chaîne de traction 11 implantée sur le train avant d'un véhicule automobile.FIGS. 1a and 1b show a traction architecture 10 for a motor vehicle 20 comprising a traction chain 11 installed on the front axle of a motor vehicle.
Cette chaîne de traction 11 comporte un moteur thermique 13 et une boîte de vitesses 16 munie d'un arbre d'entrée 16.1 et d'un arbre de sortie 16.2 connecté aux roues par l'intermédiaire d'un différentiel 17.This traction chain 11 comprises a heat engine 13 and a gearbox 16 provided with an input shaft 16.1 and an output shaft 16.2 connected to the wheels by means of a differential 17.
Un embrayage 18 est interposé entre le moteur thermique 13 et l'arbre d'entrée 16.1 de la boîte de vitesses 16.A clutch 18 is interposed between the heat engine 13 and the input shaft 16.1 of the gearbox 16.
Une machine électrique tournante 21 de type réversible est accouplée au moteur thermique 13 via la façade accessoires. Le dispositif de transmission de mouvement 22 entre le moteur thermique 13 et la machine électrique 21 pourra par exemple comporter une courroie coopérant avec des poulies portées respectivement par le vilebrequin et l'arbre de la machine électrique 21.A rotating electrical machine 21 of the reversible type is coupled to the heat engine 13 via the accessories front. The movement transmission device 22 between the heat engine 13 and the electric machine 21 may for example include a belt cooperating with pulleys carried respectively by the crankshaft and the shaft of the electric machine 21.
Cette machine électrique 21, appelée communément alterno-démarreur, est apte à fonctionner dans un mode générateur pour recharger une batterie 24 du véhicule ainsi que dans un mode moteur pour assurer un démarrage du moteur thermique 13 alors que le véhicule est à l'arrêt ou lors d'une transition d'un mode de roulage électrique vers un mode de roulage thermique. Cette machine électrique 21 pourra également être utilisée pour fournir de l'énergie îo à la batterie 24 lors d'une phase de freinage récupératif. En variante, la machine électrique 21 est un alternateur pouvant fonctionner uniquement en mode générateur.This electric machine 21, commonly called alternator-starter, is capable of operating in a generator mode for recharging a battery 24 of the vehicle as well as in an engine mode for ensuring a starting of the thermal engine 13 while the vehicle is stopped or during a transition from an electric driving mode to a thermal driving mode. This electric machine 21 can also be used to supply energy to the battery 24 during a regenerative braking phase. As a variant, the electric machine 21 is an alternator capable of operating only in generator mode.
En outre, une deuxième machine électrique tournante 26 de type réversible est accouplée avec l'arbre de sortie 16.2 de la boîte de vitesses 16. La machine électrique 26 est apte à fonctionner dans un mode générateur lors d'une phase de freinage récupératif pour recharger la batterie 24 ainsi que dans un mode moteur pour assurer un roulage électrique du véhicule.In addition, a second rotary electrical machine 26 of reversible type is coupled with the output shaft 16.2 of the gearbox 16. The electrical machine 26 is capable of operating in a generator mode during a regenerative braking phase for recharging. the battery 24 as well as in an engine mode to ensure an electric running of the vehicle.
La machine électrique 26 est associée à un onduleur qui pourra être fixé à l'arrière de la machine 26 ou être séparé de la machine 26. Le circuit de refroidissement de l'onduleur et des machines électriques 21, 26 pourra être à base d'eau ou d'huile.The electric machine 26 is associated with an inverter which can be fixed to the rear of the machine 26 or can be separated from the machine 26. The cooling circuit of the inverter and the electric machines 21, 26 can be based on water or oil.
Dans le mode de réalisation de la figure 1a, la machine électrique 26 est montée de façon coaxiale avec l'arbre de sortie 16.2 de la boîte de vitesses 16. La machine électrique 26 présente alors la même vitesse de rotation que celle du moteur thermique 13.In the embodiment of FIG. 1a, the electric machine 26 is mounted coaxially with the output shaft 16.2 of the gearbox 16. The electric machine 26 then has the same speed of rotation as that of the heat engine 13 .
Dans le mode de réalisation de la figure 1b, la machine électrique tournante 26 est montée parallèlement à l'arbre de sortie 16.2 de la boîte de vitesses 16. A cet effet, la machine électrique 26 est reliée mécaniquement à l'arbre de sortie 16.2 par l'intermédiaire d'un dispositif de transmission de mouvement 27, par exemple à engrenages, à chaîne, ou à courroie.

Comme on peut le voir sur la figure 2, les deux machines électriques tournantes 21, 26 sont connectées à un premier réseau électrique 30 sur lequel est également branchée la batterie 24. Ce réseau électrique 30 présente une tension de fonctionnement inférieure à 60 Volts. Avantageusement, la tension de fonctionnement du réseau électrique 30 est de 48 Volts. D'autres charges électriques 31 pourront également être connectées sur le réseau électrique 30.As can be seen in FIG. 2, the two rotating electrical machines 21, 26 are connected to a first electrical network 30 to which the battery 24 is also connected. This electrical network 30 has an operating voltage of less than 60 volts. Advantageously, the operating voltage of the electrical network 30 is 48 Volts. Other electrical charges 31 may also be connected to the electrical network 30.
Chaque machine électrique 21,26 pourra présenter une puissance comprise entre 15kW et 25 kW et fournir un couple compris entre 55Nm et 80Nm en fonction de sa longueur. Les machines électriques 21, 26 pourront par exemple être des machines de type synchrone à aimants permanents.Each electric machine 21,26 can have a power between 15 kW and 25 kW and provide a torque between 55Nm and 80Nm depending on its length. The electric machines 21, 26 could for example be machines of the synchronous type with permanent magnets.
Le réseau électrique 30 est interfacé avec un deuxième réseau électrique 34 basse tension par l'intermédiaire d'un convertisseur continu/continu 35. Un démarreur 36 assurant les démarrages à froid du moteur thermique 13, ainsi que des consommateurs électriques 37 du véhicule de type éclairage, actionneurs de vitres ou de sièges, et contrôle moteur, sont connectés au réseau électrique 34. Ce réseau électrique 34 associé à une batterie 40 présente une tension de fonctionnement inférieure à celle du premier réseau électrique 30. La tension de fonctionnement du réseau électrique 34 est de préférence de l'ordre de 12 Volts. Suivant certaines configurations, il est possible de supprimer la présence du démarreur 36.The electrical network 30 is interfaced with a second low voltage electrical network 34 by means of a DC / DC converter 35. A starter 36 ensuring the cold starts of the heat engine 13, as well as electrical consumers 37 of the type vehicle lighting, window or seat actuators, and engine control are connected to the electrical network 34. This electrical network 34 associated with a battery 40 has an operating voltage lower than that of the first electrical network 30. The operating voltage of the electrical network 34 is preferably of the order of 12 Volts. According to certain configurations, it is possible to remove the presence of starter 36.
Dans un mode de réalisation particulier, il sera possible d'implanter l'onduleur de la machine électrique 26 ainsi que le convertisseur 35 à l'intérieur d'un même boîtier.In a particular embodiment, it will be possible to install the inverter of the electric machine 26 as well as the converter 35 inside the same housing.
Comme cela est illustré par la figure 3, une telle architecture 10 permet, grâce à la première machine électrique 21, d'assurer une fonction d'arrêt et de redémarrage automatique du moteur thermique 13 en fonction des conditions de circulation (fonction dite STT pour stop and start en anglais).As illustrated by FIG. 3, such an architecture 10 makes it possible, thanks to the first electric machine 21, to provide an automatic stop and restart function for the heat engine 13 as a function of traffic conditions (so-called STT function for stop and start in English).
Une fonction dite boost en anglais permet à l'une et/ou l'autre des machines électriques 21, 26 d'assister ponctuellement le moteur thermiqueA so-called boost function allows one and / or the other of the electric machines 21, 26 to punctually assist the heat engine
13 lors d'une phase de roulage en mode thermique.13 during a rolling phase in thermal mode.
Une fonction de freinage récupératif permet à l'une et/ou l'autre des machines électriques 21,26 de fournir de l'énergie électrique à la batterie 24 lors d'une phase de freinage. L'utilisation simultanée des deux machines électriques 21,26 permet de maximiser l'énergie récupérée par la batterie 24 îo lors du freinage.A regenerative braking function allows one and / or the other of the electric machines 21, 26 to supply electrical energy to the battery 24 during a braking phase. The simultaneous use of the two electric machines 21, 26 makes it possible to maximize the energy recovered by the battery 24 during braking.
Une fonction de roue libre, dite de coasting en anglais, permet d'automatiser l'ouverture de la chaîne de traction 11 sans action explicite du conducteur pour réduire le régime moteur ou l'arrêter afin de minimiser la consommation en carburant ainsi que les émissions polluantes. S'il a été arrêté, la machine électrique avant 21 ou la machine 26 ou le démarreur pourra assurer le re-démarrage du moteur thermique 13.A freewheeling function, called coasting in English, makes it possible to automate the opening of the traction chain 11 without any explicit action by the driver to reduce the engine speed or stop it in order to minimize fuel consumption as well as emissions polluting. If it has been stopped, the electric machine before 21 or the machine 26 or the starter will be able to restart the thermal engine 13.
En outre, par rapport à un alterno-démarreur 21 seul, l'architecture 10 permet de disposer d'un couple électrique à l'arrêt du véhicule pour assurer notamment un décollage du véhicule (fonction dite de take off en anglais).In addition, compared to an alternator-starter 21 alone, the architecture 10 makes it possible to have an electric torque when the vehicle is stopped in order to ensure in particular a take-off of the vehicle (so-called take off function in English).
La machine électrique 26 permet également d'assurer un roulage électrique pur. Le roulage électrique pourra être sollicité juste après une sortie de phase de roulage en roue libre. Dans certaines situations de vie dans lesquelles la batterie 24 est vide, la machine électrique 21 pourra fournir directement une énergie électrique à la machine électrique 26 pour assurer une traction du véhicule.The electric machine 26 also makes it possible to ensure pure electric driving. The electric drive may be requested just after a freewheeling phase exit. In certain life situations in which the battery 24 is empty, the electric machine 21 can directly supply electric energy to the electric machine 26 to ensure traction of the vehicle.
Grâce au roulage électrique pur, à la fonction de freinage récupératif par les deux machines électriques 21, 26, ainsi qu'au poids réduit des batteries utilisées 24, 40, l'invention permet un gain en carburant de l'ordre de 20% lors des roulages sur de longues distances.Thanks to the pure electric driving, to the regenerative braking function by the two electric machines 21, 26, as well as to the reduced weight of the batteries used 24, 40, the invention allows a gain in fuel of the order of 20% during taxiing over long distances.
Lors de la transition du mode de roulage électrique vers le mode de roulage thermique, l'énergie de la batterie 24 est utilisée afin de démarrer le moteur thermique 13 avec la machine 21. Il sera possible de contrôler un niveau de charge suffisant de la batterie 24 permettant le démarrage du moteur thermique 13. Si ce n'est pas le cas, le calculateur moteur pourra commander l'arrêt du mode de roulage électrique afin de disposer d'un niveau d'énergie minimum. Le convertisseur 35 pourra également être utilisé pour transférer de l'énergie depuis la batterie 12 Volts vers la batterie 48Volts afin de garantir le démarrage du moteur thermique 13 par la machine électrique 21.During the transition from the electric driving mode to the thermal driving mode, the energy of the battery 24 is used in order to start the heat engine 13 with the machine 21. It will be possible to control a sufficient level of charge of the battery 24 allowing the engine 13 to start. If this is not the case, the engine control unit can order the stopping of the electric driving mode in order to have a minimum energy level. The converter 35 can also be used to transfer energy from the 12-volt battery to the 48-volt battery in order to guarantee the starting of the heat engine 13 by the electric machine 21.
En variante, il est possible de supprimer la machine électrique 21 accouplée îo avec le moteur thermique 13.As a variant, it is possible to omit the electric machine 21 coupled to the heat engine 13.
