20 Ces objets, caractéristiques et avantages de la présente invention seront exposés en détail dans la description suivante d'un mode d'exécution particulier fait à titre non-limitatif en relation avec l'unique figure jointe qui représente schématiquement un dispositif de gestion d'un groupe motopropulseur hybride pour véhicule automobile selon un mode 25 d'exécution. These objects, features and advantages of the present invention will be set forth in detail in the following description of a particular non-limiting embodiment in connection with the single attached figure which schematically represents a management device of the present invention. a hybrid powertrain for a motor vehicle according to a mode of execution.
La figure 1 illustre schématiquement un dispositif selon un mode d'exécution de l'invention implémenté dans le cadre d'un groupe motopropulseur regroupant un moteur thermique et un moteur électrique. 30 RENO?&FR / PJ7914 - dépôt DA 5 Un élément essentiel de l'invention consiste en l'utilisation d'un calculateur de supervision 2. Ce calculateur de supervision 2 centralise toutes les comrnandes provenant directement de la volonté du conducteur 1, qui lui sont transmises par une liaison de communication 6. Ensuite, le calculateur de supervision 2 échange des données avec un calculateur 3 dédié au contrôle du moteur électrique et avec un calculateur 4 dédié au contrôle du moteur thermique par respectivement des liaisons de communication 7 et 8. Enfin, le calculateur de supervision 2 échange des données avec un calculateur 5 dédié au contrôle du châssis par une liaison de communication 9. Il peut aussi communiquer avec un calculateur supplémentaire de gestion de la transmission, lui envoyer des inforrnations relatives à la température, le mode dégradé ou non, la mise en place du rapport, une loi de passage..., qui lui retourne alors les valeurs appliquées pour ces différents paramètres. Figure 1 schematically illustrates a device according to an embodiment of the invention implemented in the context of a power train grouping a heat engine and an electric motor. One essential element of the invention consists in the use of a supervisory computer 2. This supervision calculator 2 centralises all the commands coming directly from the will of the driver 1, which informs him or her of the instructions. are then transmitted by a communication link 6. Then, the supervision computer 2 exchanges data with a computer 3 dedicated to the control of the electric motor and with a computer 4 dedicated to the control of the engine by respectively communication links 7 and 8. Finally, the supervision computer 2 exchanges data with a computer 5 dedicated to the control of the chassis via a communication link 9. It can also communicate with an additional transmission management computer, send it information relating to the temperature, degraded mode or not, the establishment of the report, a law of passage ..., which then returns to it the values applied for these different parameters.
Ainsi, le calculateur de supervision 2 reçoit toutes les données d'entrée du véhicule qui participent à la définition du couple à transmettre au véhicule. Pour cela, il reçoit les données de nombreux capteurs, non représentés, qui lui arrivent directement par une communication représentée par une seule liaison 6 pour des raisons de simplification sur la figure 1. Ces capteurs incluent les moyens de détection de la position des pédales d'accélérateur et de freinage, du levier de sens de marche, d'un éventuel bouton définissant un comportement particulier du véhicule, par exemple pour la conduite sur neige appelé loi neige , ou de maniière équivalente toute autre loi de conduite, de boutons définissant une régulation ou une limitation de vitesse,.... Ainsi, le calculateur de supervision 2, qui peut être un moyen logiciel et/ou matériel, est directement relié à un ensemble de capteurs et d'actionneurs formant une interface avec le conducteur du véhicule automobile et lui permettant de diriger le véhicule selon sa volonté. Cette construction permet donc au calculateur de supervision 2 REN078FR / PJ7914 - dépôt DA 6 de recevoir de manière exhaustive l'ensemble des données représentant la volonté du conducteur 1 du véhicule automobile et nécessaires à la définition du couple à transmettre. Ensuite, à partir de ces données et d'une règle de gestion de l'énergie du véhicule, stockée dans une mémoire non représentée, le calculateur de supervision 2 établit des consignes de couple destinées aux calculateurs 3, 4 de contrôle des motorisations. Il tient compte de consignes de couples du châssis pour la détermination du couple à appliquer aux calculateurs 3, 4. Thus, the supervision computer 2 receives all the vehicle input data that participate in the definition of the torque to be transmitted to the vehicle. For this, it receives the data of many sensors, not shown, which arrive directly to it by a communication represented by a single link 6 for the sake of simplicity in FIG. 1. These sensors include the means for detecting the position of the pedal pedals. accelerator and braking, the operating direction lever, a possible button defining a particular behavior of the vehicle, for example for driving on snow called snow law, or in a similar manner any other driving law, buttons defining a Thus, the supervision computer 2, which may be a software and / or hardware means, is directly connected to a set of sensors and actuators forming an interface with the driver of the vehicle. automobile and allowing him to steer the vehicle as he wishes. This construction therefore allows the supervisory computer 2 REN078FR / PJ7914 - deposit DA 6 to receive exhaustively all the data representing the will of the driver 1 of the motor vehicle and necessary for the definition of the torque to be transmitted. Then, from these data and a vehicle energy management rule, stored in a memory not shown, the supervision computer 2 establishes torque setpoints for control computers 3, 4 control engines. It takes into account the torque requirements of the chassis for determining the torque to be applied to the computers 3, 4.
Finalement, le calculateur de supervision peut piloter tous les organes participant à la motricité du véhicule comme la répartition du couple entre les trains avant et arrière, la prise en compte des requêtes du châssis, et détermine le meilleur point de fonctionnement du groupe motopropulseur en fonction des potentiels et de l'état énergétique du véhicule, tenant compte par exemple du niveau de carburant fossile et du niveau de charge de la batterie pour une traction électrique. Finally, the supervision computer can control all the components involved in the traction of the vehicle such as the distribution of the torque between the front and rear trains, taking into account the requests of the chassis, and determines the best operating point of the powertrain according to potentials and the energy state of the vehicle, taking into account, for example, the level of fossil fuel and the level of charge of the battery for electric traction.
D'autre part, selon le concept de l'invention, chaque motorisation du groupe motopropulseur hybride conserve son propre calculateur 3, 4 de contrôle de son fonctionnement, similaire à celui habituellement utilisé pour ces motorisations dans des situations conventionnelles. Toutefois, selon l'invention, ce calculateur comprend un moyen de communication 7, 8 avec le calculateur de supervision 2, afin de recevoir les consignes de couples mentionnées précédemment. De plus, il se comporte comme esclave du calculateur de supervision 2 selon une relation maître / esclave. Il retourne aussi au calculateur de supervision 2 des informations sur le rapport engagé ou le régime, la température, le mode dégradé, la pollution éventuelle... On the other hand, according to the concept of the invention, each motorization of the hybrid powertrain retains its own computer 3, 4 control of its operation, similar to that usually used for these engines in conventional situations. However, according to the invention, this calculator comprises a communication means 7, 8 with the supervision computer 2, in order to receive the torque setpoints mentioned above. In addition, it acts as a slave of the supervision computer 2 according to a master / slave relationship. It also returns to the supervision computer 2 information on the gear engaged or the speed, the temperature, the degraded mode, the possible pollution ...
REN073FR / PJ7914 - dépôt DA 7 Selon le mode d'exécution avantageux décrit, le dispositif comprend de plus un calculateur 5 de contrôle du châssis du véhicule automobile, qui reçoit aussi des consignes de couples du calculateur de supervision 2. Ce calculateur 5 met par exemple en oeuvre le contrôle des fonctions de type ABS, ESP, 4RD, MSR, ASR, AFU...II est aussi relié au calculateur de supervision 2 selon une relation maître / esclave. Il renvoie des informations au calculateur de supervision 2 en fonction de la détection de diverses prestations du châssis. REN073FR / PJ7914 - DA depot 7 According to the advantageous embodiment described, the device further comprises a control computer 5 of the chassis of the motor vehicle, which also receives torque instructions from the supervision computer 2. This calculator 5 sets by For example, the control of the ABS, ESP, 4RD, MSR, ASR, AFU type functions is used. It is also connected to the supervision computer 2 according to a master / slave relationship. It sends back information to the supervision computer 2 according to the detection of various services of the chassis.
Le dispositif décrit précédemment pourra être mis en oeuvre par la réunion de divers moyens matériels et/ou logiciels selon plusieurs combinaisons possobles. The device described above may be implemented by the combination of various hardware and / or software according to several possoble combinations.
Ainsi, la solution décrite atteint bien les objets recherchés et présente les 15 avantages suivants : Elle est compatible et transposable à tout type de groupe motopropulseur hybride puisqu'elle se présente sous une forme modulaire. Tout type de motorisation, par exemple essence, diesel, quatre ou six cylindres, ... peut être relié au calculateur de 20 supervision selon le schéma explicité ci-dessus. La solution convient donc bien à tout groupe motopropulseur comprenant au moins deux motorisations quelconques de type différent ; De plus, la solution repose sur l'ajout d'un calculateur de supervision de relativement petite dimension : la solution est donc 25 simple et économique. Thus, the described solution achieves the desired objects and has the following advantages: It is compatible and can be transposed to any type of hybrid powertrain since it is in a modular form. Any type of engine, for example gasoline, diesel, four or six cylinders, ... can be connected to the supervision computer according to the diagram explained above. The solution is therefore well suited to any powertrain comprising at least two engines of any type different; In addition, the solution relies on the addition of a relatively small supervision computer: the solution is therefore simple and economical.
