ARCHITECTURE DE TRACTION POUR VÉHICULE AUTOMOBILE À ONDULEUR ET CONVERTISSEUR DE PUISSANCE INTÉGRÉS  TENSION ARCHITECTURE FOR INTEGRATED MOTOR VEHICLE WITH INVERTER AND POWER CONVERTER
La présente invention porte sur une architecture de traction pour véhicule automobile à onduleur et convertisseur de puissance intégrés. De façon connue en soi, une chaîne de traction hybride comporte un moteur thermique accouplé à une boîte de vitesses par l'intermédiaire d'un embrayage ainsi qu'une ou plusieurs machines électriques réversibles implantées sur un des trains du véhicule. The present invention relates to a traction architecture for a motor vehicle with integrated inverter and power converter. In a manner known per se, a hybrid power train comprises a heat engine coupled to a gearbox via a clutch and one or more reversible electrical machines installed on one of the trains of the vehicle.
Ces machines électriques sont généralement des machines réversibles aptes 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, et le cas échéant un roulage électrique. Chaque machine électrique pourra également être utilisée pour fournir de l'énergie à la batterie lors d'une phase de freinage récupératif. Dans les architectures hybrides existantes, les composants électroniques sont généralement dédiés à une fonction prédéterminée. Ainsi, par exemple, on prévoit un onduleur associé à la machine électrique tournante, un convertisseur de puissance continu-continu pour assurer la transformation de puissance d'un réseau électrique à l'autre du véhicule, une unité de contrôle dédiée à la commande d'un embrayage piloté ainsi qu’une unité de contrôle dédiée à la commande d'un dispositif de désaccouplement de la machine électrique avec les roues lorsque la vitesse du véhicule devient supérieure à un seuil, ainsi qu'une unité de contrôle dédiée à la commande d'un dispositif de blocage de roues à l'arrêt du véhicule. Une telle configuration présente toutefois l'inconvénient d'être encombrante, dans la mesure où un espace doit être prévu pour l'implantation des différents composants distincts les uns des autres. Il est également difficile d'assurer la communication entre les différents composants. En outre, le coût de réalisation du système est important, tandis que la sûreté de fonctionnement est complexe à assurer, dans la mesure où il est nécessaire de prévoir des redondances pour les composants pris individuellement. La présente invention vise à remédier efficacement à au moins un de ces inconvénients en proposant une architecture de traction pour véhicule automobile comportant: These electrical machines are generally reversible machines capable of operating in a generator mode for recharging a vehicle battery as well as in an engine mode to ensure starting of the engine, and if necessary electric taxiing. Each electric machine can also be used to provide energy to the battery during a regenerative braking phase. In existing hybrid architectures, the electronic components are generally dedicated to a predetermined function. Thus, for example, there is provided an inverter associated with the rotating electrical machine, a DC-DC power converter to ensure power transformation from one electrical network to the other of the vehicle, a control unit dedicated to the control of the a controlled clutch and a control unit dedicated to the control of a device for disconnecting the electric machine from the wheels when the vehicle speed becomes greater than a threshold, and a control unit dedicated to the control a wheel lock device when the vehicle is stopped. Such a configuration, however, has the disadvantage of being cumbersome, insofar as a space must be provided for the implementation of different components separate from each other. It is also difficult to ensure communication between the different components. In addition, the cost of achieving the system is important, while the dependability is complex to ensure, as it is necessary to provide redundancy for individual components. The present invention aims to effectively remedy at least one of these disadvantages by providing a traction architecture for a motor vehicle comprising:
- au moins une machine électrique tournante implantée sur un train du véhicule automobile par l'intermédiaire d'un réducteur de vitesse en prise avec un différentiel dudit train munies de roues,  at least one rotating electrical machine implanted on a train of the motor vehicle by means of a speed reducer engaged with a differential of said train provided with wheels,
- au moins un onduleur associé à ladite machine électrique tournante, caractérisée en ce que, sont regroupés à l’intérieur d’un même boîtier commun, avec l'onduleur :  - At least one inverter associated with said rotary electrical machine, characterized in that, are grouped together within the same common housing, with the inverter:
- un convertisseur de puissance pour interfacer un premier réseau électrique et un deuxième réseau électrique du véhicule automobile, et/ou  a power converter for interfacing a first electrical network and a second electrical network of the motor vehicle, and / or
- une unité de contrôle d’un dispositif de désaccouplement de la machine électrique tournante par rapport aux roues et une unité de contrôle d’un dispositif de blocage des roues à l'arrêt du véhicule automobile intégré dans le différentiel.  - A control unit of a device for uncoupling the electric machine rotating relative to the wheels and a control unit of a wheel lock device at the stop of the motor vehicle integrated in the differential.
L'invention permet ainsi, en regroupant l'onduleur et le convertisseur, de limiter l'encombrement du système et donc de faciliter son intégration dans le véhicule. The invention thus makes it possible, by grouping the inverter and the converter, to limit the size of the system and thus to facilitate its integration into the vehicle.

Un microprocesseur pourra être dédié à la sûreté de fonctionnement de l'onduleur de puissance 30, du dispositif de désaccouplement 41 , et du dispositif de blocage 48. A microprocessor may be dedicated to the operational safety of the power inverter 30, the uncoupling device 41, and the blocking device 48.
Avantageusement, le capteur 46 du dispositif de désaccouplement 41 et/ou les capteurs 52 du dispositif de blocage 48 sont reliés au boîtier commun 53. Comme on peut le voir sur la figure 4, le dispositif de désaccouplement 41 comporte un actionneur à électro-aimant 42 apte à commander l'engagement d'un crabot 45 avec une pièce de liaison 44 correspondante reliée aux roues 27 du véhicule. Pour des raisons de sécurité, le crabot 45 est par défaut dans un état déverrouillé si aucun courant n'est appliqué à l'électro-aimant. Advantageously, the sensor 46 of the uncoupling device 41 and / or the sensors 52 of the blocking device 48 are connected to the common housing 53. As can be seen in Figure 4, the uncoupling device 41 comprises an electromagnet actuator 42 adapted to control the engagement of a clutch 45 with a corresponding connecting piece 44 connected to the wheels 27 of the vehicle. For safety reasons, the clutch 45 is by default in an unlocked state if no current is applied to the electromagnet.
Pour faire passer le dispositif 41 d'un état déverrouillé à un état verrouillé, la machine électrique 23 synchronise son régime avec celui des roues 27 au rapport de démultiplication près. Lors de la reconnexion, le contrôle du courant est effectué, de sorte que l'actionneur à électro-aimant 42 engage le crabot 45 dans la pièce de liaison 44. To move the device 41 from an unlocked state to a locked state, the electric machine 23 synchronizes its speed with that of the wheels 27 to the gear ratio. Upon reconnection, the current control is performed, so that the electromagnet actuator 42 engages the clutch 45 in the connecting piece 44.
Suivant un exemple de mise en oeuvre, la synchronisation et la connexion de la machine électrique 23 avec les roues 27 présente une durée inférieure à 600 ms. La consommation de courant de l'électroaimant ne doit pas être supérieure à 5A et de préférence inférieure à 2A lorsque le dispositif de désaccouplement 41 est à l'état verrouillé. According to an exemplary implementation, the synchronization and the connection of the electric machine 23 with the wheels 27 has a duration of less than 600 ms. The current consumption of the electromagnet must not be greater than 5A and preferably less than 2A when the uncoupling device 41 is in the locked state.
Le dispositif 41 comporte au moins un capteur 46 apte à renvoyer la position du crabot 45 afin que l'unité de contrôle 31.2 puisse confirmer la reconnexion de la machine électrique tournante 23. The device 41 comprises at least one sensor 46 able to return the position of the clutch 45 so that the control unit 31.2 can confirm the reconnection of the rotating electrical machine 23.
Comme cela est illustré sur les figures 5a et 5b, le dispositif de blocage 48 comporte un loquet 50 mobile entre une position déverrouillée dans laquelle le loquet 50 est dégagé des dents d'un pignon 51 d'un arbre relié directement ou indirectement aux roues 27 (cf. figure 4a) et une position verrouillée dans laquelle le loquet 50 est en prise avec les dents du pignon 51 (cf. figure 4b). Le dispositif de blocage 48 comporte également des capteurs 52 nécessaires pour garantir la sûreté de son fonctionnement. As illustrated in Figures 5a and 5b, the locking device 48 comprises a latch 50 movable between an unlocked position in which the latch 50 is disengaged from the teeth of a pinion 51 of a shaft connected directly or indirectly to the wheels 27 (See Figure 4a) and a locked position in which the latch 50 is engaged with the teeth of the pinion 51 (Figure 4b). The blocking device 48 also includes sensors 52 necessary to guarantee the safety of its operation.
Suivant une variante de réalisation, il sera possible d'implanter une machine électrique 23' supplémentaire sur le train arrière 24, afin d'augmenter la puissance et le couple disponible en mode de roulage électrique. Cette machine électrique 23' est associée à un onduleur de puissance 30'. Une des deux machines électriques 23, 23' étant définie comme une machine maître, le convertisseur de puissance 37, et le cas échéant l'unité de contrôle 42 et/ou le chargeur 43, sont intégrés à l'intérieur du boîtier 53 de l'onduleur de puissance 30, 30' de la machine électrique tournante maître. According to an alternative embodiment, it will be possible to implement an additional electric machine 23 'on the rear axle 24, in order to increase the power and the torque available in electric driving mode. This electric machine 23 'is associated with a power inverter 30'. One of the two electrical machines 23, 23 'being defined as a master machine, the power converter 37, and if necessary the control unit 42 and / or the charger 43, are integrated inside the housing 53 of the power inverter 30, 30 'of the master rotating electrical machine.
Bien entendu, la description qui précède a été donnée à titre d'exemple uniquement et ne limite pas le domaine de l'invention dont on ne sortirait pas en remplaçant les différents éléments par tous autres équivalents. Of course, the foregoing description has been given by way of example only and does not limit the scope of the invention which would not be overcome by replacing the different elements by any other equivalent.
En outre, les différentes caractéristiques, variantes, et/ou formes de réalisation de la présente invention peuvent être associées les unes avec les autres selon diverses combinaisons, dans la mesure où elles ne sont pas incompatibles ou exclusives les unes des autres. In addition, the various features, variations, and / or embodiments of the present invention may be associated with each other in various combinations, to the extent that they are not incompatible or exclusive of each other.
