Description

VEHICULE HYBRIDE pool La présente invention concerne de manière générale un véhicule automobile hybride et plus particulièrement un véhicule utilisant plusieurs sources d'énergies pour entraîner plusieurs groupes motopropulseurs. [0002] II est connu dans l'art antérieur des véhicules hybrides comprenant une source d'énergie non-réversible thermique tel qu'un moteur à combustion interne et une source d'énergie réversible tel qu'un moteur électrique. L'utilisation combinée de ces sources d'énergie permet de réduire la consommation du véhicule et le coût lié à son utilisation. Les sources d'énergie réversible peuvent se classer en deux types, un type favorisant la puissance permettant ainsi un gain de consommation et un type favorisant le stockage d'énergie procurant ainsi une autonomie appréciable. Les sources d'énergie réversible connues ne peuvent généralement pas cumuler puissance et stockage. Il faut donc les sur dimensionner, entraînant des surcouts et des difficultés de packaging liés à un volume et une masse plus importants que le strict nécessaire. [0003] Un but de la présente invention est de répondre aux inconvénients mentionnés ci-dessus et en particulier, tout d'abord, de fournir un véhicule disposant d'un système d'entraînement alimenté par de l'énergie propre capable de fournir une grande puissance et une grande quantité de stockage tout en procurant une excellente modularité au système. [0004] Pour cela un premier aspect de l'invention concerne un véhicule automobile hybride comprenant un premier groupe motopropulseur utilisant une énergie non réversible et un second groupe motopropulseur utilisant un premier type d'énergie réversible, agencés pour entraîner un premier train du véhicule, caractérisé en ce qu'il comprend en outre un troisième groupe motopropulseur utilisant un second type d'énergie réversible différent du premier type d'énergie réversible, agencé pour entraîner un second train du véhicule. De cette manière, le véhicule dispose de plusieurs groupes motopropulseurs qui sont agencés dans le véhicule sans encombrements car disposés sur les deux trains du véhicule tout en permettant un gain de consommation et une grande autonomie grâce aux deux types d'énergie employés. [0005] Une réalisation particulièrement intéressante consiste en ce que l'un du second et du troisième groupe motopropulseur est agencé pour favoriser une production de puissance et l'autre du second et du troisième groupe motopropulseur est agencé pour favoriser un stockage d'énergie. Ainsi, le véhicule dispose à la fois d'une réserve d'énergie et d'une capacité de puissance élevées. [0006] De manière avantageuse, les second et troisième groupes motopropulseurs sont des moteurs ZEV. De cette manière, le véhicule est écologiquement efficient. [0007] Une réalisation particulièrement intéressante consiste en ce que le second groupe motopropulseur est un moteur hydraulique, un moteur électrique alimenté par des super-capacités ou un volant d'inertie entraîné par une machine électrique. Ainsi, le second groupe motopropulseur produit une grande quantité de puissance de manière fiable. mos] De manière avantageuse, les premier et second groupes motopropulseurs entraînent le premier train via une première boîte de vitesse hybride et le troisième groupe motopropulseur entraîne le second train via une seconde boîte de vitesse. Ainsi, les différents trains du véhicule peuvent être entraînés indépendamment l'un de l'autre. [0009] Avantageusement, le troisième groupe motopropulseur est un moteur électrique alimenté par une batterie. De cette manière, le troisième groupe motopropulseur dispose d'une grande quantité d'énergie de manière fiable. [0olo] De manière avantageuse, la batterie est une batterie manuellement rechargeable. De cette manière, un utilisateur peut lui-même choisir quand recharger sa batterie. [0011] Une réalisation particulièrement intéressante consiste en ce qu'au 5 moins l'un du second et du troisième groupe motopropulseur est agencé de sorte pouvoir se recharger par prélèvement de couple de l'autre du second et du troisième groupe motopropulseur lorsque le premier groupe motopropulseur est éteint. De cette manière, les groupes motopropulseurs peuvent se recharger l'un l'autre sans avoir besoin d'utiliser le premier 10 groupe motopropulseur. [0012] De manière avantageuse, le premier train du véhicule est le train avant et le second train du véhicule est le train arrière. Ainsi, le véhicule dispose d'un entraînement par quatre roues motrices. [0013] Avantageusement, le premier groupe motopropulseur est un moteur 15 thermique. De cette manière, le véhicule dispose d'un moteur présentant une puissance et une autonomie considérables. [0014] D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description détaillée qui suit d'un mode de réalisation de l'invention donné à titre d'exemple nullement 20 limitatif et illustré par le dessin annexé, dans lequel : - la figure 1 représente une vue schématique de haut d'un véhicule de la présente invention. [0015] La figure 1 représente un véhicule automobile hybride 4 selon un mode de réalisation préféré de la présente invention. Ce véhicule 4 25 comprend un train avant 5 entraîné, via une première boîte de vitesse hybride 7, par un moteur hybride. Ce moteur hybride comprend un premier groupe motopropulseur 1 à énergie non-réversible, par exemple un moteur à combustion interne, et un second groupe motopropulseur 2 à énergie réversible, de préférence un moteur ZEV (zéro émission CO2) orienté puissance, favorisant une génération de puissance et de couple par rapport à une capacité de stockage d'énergie, tel qu'un moteur hydraulique ou un moteur électrique alimenté par des super-capacités ou un volant d'inertie entraîné par une machine électrique. [0016] Le véhicule 4 comprend également un train arrière 6 entraîné, via une seconde boîte de vitesse 8, par un troisième groupe motopropulseur 3 à énergie réversible différente de l'énergie utilisée par le second groupe motopropulseur 2, de préférence un moteur ZEV orienté énergie, favorisant une capacité de stockage d'énergie à une génération de puissance et de couple, tel qu'une batterie. Cette batterie n'aura pas à intégrer de contraintes liées à une génération de puissance importante, elle pourra donc utiliser des technologies optimisant sa masse et son volume. Cette batterie pourra également être manuellement rechargeable via une installation externe. [0017] Les différents groupes motopropulseurs sont agencés dans le véhicule de sorte que lorsque le moteur à combustion interne est éteint, au moins l'un du second et du troisième groupe motopropulseur peut se recharger par prélèvement de couple de l'autre du second et du troisième groupe motopropulseur. [0018] On comprendra que diverses modifications et/ou améliorations évidentes pour l'homme du métier peuvent être apportées aux différents modes de réalisation de l'invention décrits dans la présente description sans sortir du cadre de l'invention défini par les revendications annexées. En particulier, il est fait référence aux différents types de sources d'énergie, au nombre maximum de groupes motopropulseurs ainsi qu'à leur dimensionnement.The present invention relates generally to a hybrid motor vehicle and more particularly to a vehicle using several energy sources to drive several powertrains. [0002] Hybrid vehicles comprising a non-reversible thermal energy source such as an internal combustion engine and a reversible energy source such as an electric motor are known in the prior art. The combined use of these energy sources makes it possible to reduce the consumption of the vehicle and the cost associated with its use. The reversible energy sources can be classified into two types, a type favoring the power thus allowing a gain in consumption and a type favoring the storage of energy thus providing an appreciable autonomy. Known reversible energy sources generally can not combine power and storage. It is therefore necessary to over size, resulting in surcouts and packaging difficulties related to a volume and a mass greater than the strictly necessary. An object of the present invention is to meet the disadvantages mentioned above and in particular, first, to provide a vehicle with a drive system powered by clean energy capable of providing a high power and a large amount of storage while providing excellent modularity to the system. For this a first aspect of the invention relates to a hybrid motor vehicle comprising a first power unit using a non-reversible energy and a second powertrain using a first type of reversible energy, arranged to drive a first train of the vehicle, characterized in that it further comprises a third power unit using a second type of reversible energy different from the first type of reversible energy, arranged to drive a second train of the vehicle. In this way, the vehicle has several powertrains which are arranged in the vehicle without congestion because arranged on the two trains of the vehicle while allowing a gain in consumption and a long battery life thanks to the two types of energy used. A particularly interesting embodiment is that one of the second and third powertrain is arranged to promote power generation and the other of the second and third powertrain is arranged to promote energy storage. Thus, the vehicle has both a reserve of energy and a high power capacity. Advantageously, the second and third powertrains are ZEV engines. In this way, the vehicle is ecologically efficient. A particularly interesting embodiment is that the second powertrain is a hydraulic motor, an electric motor powered by super-capacity or a flywheel driven by an electric machine. Thus, the second powertrain produces a large amount of power reliably. Advantageously, the first and second powertrains drive the first train via a first hybrid gearbox and the third powertrain drives the second train via a second gearbox. Thus, the different trains of the vehicle can be driven independently of one another. [0009] Advantageously, the third powertrain is an electric motor powered by a battery. In this way, the third power unit has a large amount of energy reliably. [0olo] Advantageously, the battery is a manually rechargeable battery. In this way, a user can choose himself when to recharge his battery. A particularly interesting embodiment consists in that at least one of the second and third powertrain is arranged so that it can be recharged by drawing torque from the other of the second and third powertrains when the first powertrain is off. In this way, the powertrains can recharge each other without needing to use the first powertrain. Advantageously, the first train of the vehicle is the front gear and the second train of the vehicle is the rear axle. Thus, the vehicle has a four-wheel drive. [0013] Advantageously, the first powertrain is a thermal engine. In this way, the vehicle has an engine with considerable power and autonomy. Other features and advantages of the present invention will appear more clearly on reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the appended drawing. , in which: - Figure 1 shows a schematic top view of a vehicle of the present invention. Figure 1 shows a hybrid motor vehicle 4 according to a preferred embodiment of the present invention. This vehicle 4 comprises a driven front axle 5, via a first hybrid gearbox 7, by a hybrid engine. This hybrid engine comprises a first power unit 1 with non-reversible energy, for example an internal combustion engine, and a second power unit 2 with reversible energy, preferably a ZEV (zero CO2 emission) power oriented engine, promoting a generation of power and torque relative to an energy storage capacity, such as a hydraulic motor or an electric motor powered by super-capacitors or a flywheel driven by an electric machine. The vehicle 4 also comprises a rear train 6 driven, via a second gearbox 8, a third powertrain 3 reversible energy different from the energy used by the second powertrain 2, preferably a ZEV engine oriented energy, promoting an energy storage capacity to a power generation and torque, such as a battery. This battery will not have to integrate constraints related to a significant power generation, so it can use technologies that optimize its mass and volume. This battery can also be manually rechargeable via an external installation. The various powertrains are arranged in the vehicle so that when the internal combustion engine is off, at least one of the second and the third powertrain can be recharged by drawing torque from the other of the second and third powertrain. It will be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the various embodiments of the invention described in this description without departing from the scope of the invention defined by the appended claims. In particular, reference is made to the different types of energy sources, the maximum number of powertrains and their design.
