Description
ARCHITECTURE DE TRACTION POUR VÉHICULE AUTOMOBILE À RÉPARTITION VECTORIELLE DE COUPLETRACTION ARCHITECTURE FOR MOTOR VEHICLE WITH VECTOR TORQUE DISTRIBUTION
La présente invention porte sur une architecture de traction pour véhicule automobile à répartition vectorielle de couple. L'invention trouve une application particulièrement avantageuse avec les véhicules automobiles à deux ou quatre roues motrices.The present invention relates to a traction architecture for a motor vehicle with vector distribution of torque. The invention finds a particularly advantageous application with motor vehicles with two or four-wheel drive.
De façon connue en soi, les architectures de traction peuvent comporter différentiel à répartition vectorielle de couple (dite technologie de Torque vectoring en anglais) apte à imposer un couple différent à chacune des roues motrices d’un véhicule automobile.In a manner known per se, traction architectures can include a differential vector distribution of torque (known as Torque vectoring technology) capable of imposing a different torque on each of the drive wheels of a motor vehicle.
Par exemple, lors d'une phase de roulage en virage, le dispositif fournit un couple élevé à la roue extérieure pour aider à l’inscription dans la courbe. En sortie de virage, le calculateur du système cherche à contrecarrer l'effet de survirage et aide à la ré-accélération en répartissant le couple sur l’autre roue. Ce système met généralement en œuvre des dispositifs mécaniques basés sur des ensembles à trains épicycloïdaux et/ou des systèmes hydrauliques.For example, during a cornering phase, the device provides a high torque to the outer wheel to help the entry into the curve. At the end of a turn, the system's computer seeks to counteract the oversteer effect and helps re-acceleration by distributing the torque on the other wheel. This system generally implements mechanical devices based on sets of planetary gears and / or hydraulic systems.

La figure 1 est une représentation schématique d'une architecture de traction pour véhicule automobile selon la présente invention à répartition vectorielle de couple;FIG. 1 is a schematic representation of a traction architecture for a motor vehicle according to the present invention with vector distribution of torque;
La figure 2 est une représentation schématique d'une première variante de réalisation de l'architecture de traction selon l'invention munie d'un onduleur et d'un dispositif de commande d'embrayages électroniques intégrés à l'intérieur d'un même boîtier;Figure 2 is a schematic representation of a first alternative embodiment of the traction architecture according to the invention provided with an inverter and an electronic clutch control device integrated inside the same housing ;

Les éléments identiques, similaires, ou analogues, conservent la même référence d’une figure à l’autre.Identical, similar, or analogous elements retain the same reference from one figure to another.
La figure 1 montre une architecture de traction 10 pour véhicule automobile comportant, sur le train avant 11, un moteur thermique 12 accouplé à une boîte de vitesses 13 par l'intermédiaire d'un embrayage 15. La boîte de vitesses 13 est reliée mécaniquement à un différentiel 16 du train avant 11. L'embrayage 15 et la boîte de vitesses 13 pourront être ou non de type piloté, c’est-à-dire que leur fonctionnement (ouverture et fermeture de l'embraye ainsi que le passage d'un rapport de vitesse) est commandé de façon automatique par un calculateur moteur du véhicule sans action de la part du conducteur. En variante, la boîte de vitesses 13 est de type manuelle ou automatique.FIG. 1 shows a traction architecture 10 for a motor vehicle comprising, on the front axle 11, a heat engine 12 coupled to a gearbox 13 by means of a clutch 15. The gearbox 13 is mechanically connected to a differential 16 of the front axle 11. The clutch 15 and the gearbox 13 may or may not be of the piloted type, that is to say that their operation (opening and closing of the clutch as well as the passage of a speed ratio) is automatically controlled by a vehicle engine control unit without any action on the part of the driver. Alternatively, the gearbox 13 is of the manual or automatic type.
Une machine électrique 18 de type réversible est accouplée au moteur thermique 12 via la façade accessoires par l'intermédiaire d'un dispositif de transmission de mouvement 20. Le dispositif de transmission de mouvement 20 entre le moteur thermique 12 et la machine électrique 18 pourra par exemple être à courroie ou à chaîne.An electric machine 18 of the reversible type is coupled to the heat engine 12 via the accessories front panel by means of a movement transmission device 20. The movement transmission device 20 between the heat engine 12 and the electric machine 18 may by example be belt or chain.
Cette machine électrique 18, 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 12 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 18 pourra également être utilisée pour fournir de l'énergie à la batterie lors d'une phase de freinage récupératif.This electric machine 18, 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 12 while the vehicle is stopped or at a transition from an electric driving mode to a thermal driving mode. This electric machine 18 can also be used to supply energy to the battery during a regenerative braking phase.
Par ailleurs, le train 21 comporte une première roue 22.1 et une deuxième roue 22.2. Une machine électrique 24 associée à un onduleur de puissance 25 est montée sur le train 21. Cette machine électrique 24 est accouplée à un différentiel mécanique 27. Le train 21 est ici le train arrière mais en variante, l'architecture pourra être inversée, le train 21 étant le train avant 11 et le train 11 étant le train arrière. Alternativement, le véhicule automobile pourra également être dépourvu de groupe moto-propulseur thermique et être de type purement électrique.Furthermore, the train 21 comprises a first wheel 22.1 and a second wheel 22.2. An electric machine 24 associated with a power inverter 25 is mounted on the train 21. This electric machine 24 is coupled to a mechanical differential 27. The train 21 is here the rear train but in a variant, the architecture could be reversed, the train 21 being the front train 11 and train 11 being the rear train. Alternatively, the motor vehicle may also be devoid of thermal engine unit and be of the purely electric type.
En outre, un premier embrayage électronique 29.1 (dit e-clutch en anglais) est monté entre la première roue 22.1 et le différentiel 27, et un deuxième embrayage électronique 29.2 est monté entre la deuxième roue 22.2 et le différentiel 27. Un dispositif de commande 30 du premier embrayage 29.1 et du deuxième embrayage 29.2 est apte à adresser un couple de façon privilégié sur une roue 22.1, 22.2 en fonction de condition de roulage du véhicule automobile.In addition, a first electronic clutch 29.1 (called e-clutch in English) is mounted between the first wheel 22.1 and the differential 27, and a second electronic clutch 29.2 is mounted between the second wheel 22.2 and the differential 27. A control device 30 of the first clutch 29.1 and of the second clutch 29.2 is able to address a torque in a privileged manner on a wheel 22.1, 22.2 as a function of the running condition of the motor vehicle.
Ces conditions de roulage correspondent notamment à une phase de roulage en virage qui pourra être détectée à l'aide d'un ou plusieurs capteurs implantés sur volant et/ou les roues du véhicule, ou à une phase de freinage d'urgence.These driving conditions correspond in particular to a phase of rolling in a bend which can be detected using one or more sensors located on the steering wheel and / or the wheels of the vehicle, or to an emergency braking phase.
La machine électrique 24 est apte à être pilotée dans deux sens de rotation. Dans les deux sens de rotation, la machine électrique 24 peut fournir un couple positif en mode moteur ou un couple négatif en mode générateur pour recharger une batterie du véhicule.The electric machine 24 is able to be controlled in two directions of rotation. In both directions of rotation, the electric machine 24 can supply a positive torque in engine mode or a negative torque in generator mode to recharge a vehicle battery.
La machine électrique 24 est apte à être utilisée avec une fonction de roulage électrique et/ou une fonction de récupération d'énergie électrique au freinage et/ou une fonction de parking en mode électrique.The electric machine 24 is able to be used with an electric driving function and / or an electric energy recovery function when braking and / or a parking function in electric mode.
Comme cela est illustré par la figure 1, le dispositif de commande 30 pourra être externe à l'onduleur de puissance de la machine électrique 24.As illustrated in FIG. 1, the control device 30 could be external to the power inverter of the electric machine 24.
Alternativement, comme cela est illustré par la figure 2, l'onduleur de puissance 25 ainsi que le dispositif de commande 30 sont regroupés à l'intérieur d'un même boîtier commun 32. Le boîtier commun 32 est de préférence le boîtier de l'onduleur 25. L'onduleur de puissance 25 ainsi que le dispositif de commande 30 partagent des composants communs, tels qu'un dissipateur thermique et/ou une carte électronique et/ou des connecteurs, etc...Alternatively, as illustrated in FIG. 2, the power inverter 25 as well as the control device 30 are grouped together inside the same common housing 32. The common housing 32 is preferably the housing of the inverter 25. The power inverter 25 as well as the control device 30 share common components, such as a heat sink and / or an electronic card and / or connectors, etc.
Les machines électriques tournantes 18, 24 sont connectées à un premier réseau électrique 33 sur lequel est également reliée la batterie 35. Une tension de fonctionnement du réseau électrique 33 et donc des machines 18, 24 est de préférence inférieure à 60 Volts. Avantageusement, la tension de fonctionnement du réseau électrique 33 est de 48 Volts. D'autres charges électriques pourront également être connectées sur le réseau électrique 33.The rotating electrical machines 18, 24 are connected to a first electrical network 33 to which the battery 35 is also connected. An operating voltage of the electrical network 33 and therefore of the machines 18, 24 is preferably less than 60 volts. Advantageously, the operating voltage of the electrical network 33 is 48 Volts. Other electrical charges may also be connected to the electrical network 33.
Chaque machine électrique 18, 24 pourra présenter une puissance comprise entre 10kW et 30 kW et fournir un couple compris entre 55Nm et 100Nm. Les machines électriques 18, 24 pourront par exemple être des machines de type synchrone à aimants permanents. Le circuit de refroidissement des machines électriques 18, 24 pourra être à base d'eau ou d'huile.Each electric machine 18, 24 may have a power between 10 kW and 30 kW and provide a torque between 55Nm and 100Nm. The electrical machines 18, 24 could for example be machines of the synchronous type with permanent magnets. The cooling circuit of the electrical machines 18, 24 may be based on water or oil.
Le réseau électrique 33 est interfacé avec un deuxième réseau électrique 38 basse tension par l'intermédiaire d'un convertisseur de puissance continu/continu 39. Le calculateur moteur 40 ainsi que des consommateurs électriques 41 du véhicule de type éclairage, actionneurs de vitres ou de sièges sont connectés au réseau électrique 38.
