Description

VEHICULE HYBRIDE HYDRAULIQUE A STOCKEUR D'ENERGIE ELECTRIQUE IMPLANTE DE MANIERE OPTIMISEE  HYDRID HYDRAULIC VEHICLE WITH ELECTRIC ENERGY STORER IMPLANTED IN OPTIMIZED MANNER
La présente invention concerne un véhicule hybride utilisant une énergie hydraulique, dans lequel sont implantées des cellules de stockage d'énergie électrique de type « supercondensateurs » ou « supercapacités » désignés également par UCAPs, pour alimenter le réseau électrique de bord du véhicule et/ou suppléer la batterie standard du véhicule, notamment dans les phases de démarrage du moteur thermique. The present invention relates to a hybrid vehicle using a hydraulic energy, in which are implanted electrical energy storage cells of the "supercapacitor" or "supercapacities" type, also designated by UCAPs, for supplying the on-board electrical network of the vehicle and / or replace the standard battery of the vehicle, especially in the starting phases of the engine.
Les véhicules hybrides comportent une chaîne de traction comprenant un moteur thermique qui entraîne une pompe hydraulique, afin de recharger des accumulateurs de pression hydraulique pour stocker cette énergie.  Hybrid vehicles comprise a power train comprising a heat engine which drives a hydraulic pump, in order to recharge hydraulic pressure accumulators for storing this energy.
Il est connu de la demande de brevet en France n ° 1 153273, déposée par la demanderesse, d'implanter les accumulateurs de pression de forme tubulaire allongée, sous le sous-bassement du véhicule.  It is known from French Patent Application No. 1 153273, filed by the Applicant, to implant elongated tubular pressure accumulators under the underbase of the vehicle.
La figure 1 illustre, par une vue de dessous, schématique et partielle, un véhicule hybride hydraulique 10 comprenant une transmission hydrostatique dont les principaux composants sont notamment le moteur hydraulique 18, le bloc hydraulique 8 et les accumulateurs de pression 33, 34.  FIG. 1 is a diagrammatic partial view of a hydraulic hybrid vehicle 10 comprising a hydrostatic transmission, the main components of which are in particular the hydraulic motor 18, the hydraulic block 8 and the pressure accumulators 33, 34.
Les accumulateurs de pression 33, 34 constituent chacun un tube allongé de section circulaire réduite, ce qui est favorable pour limiter les contraintes dans cet accumulateur. L'accumulateur de haute pression 33 est disposé sous le sous-bassement 50 du véhicule, longitudinalement dans l'axe XX' de ce véhicule. L'accumulateur basse pression 34 est fixé rigidement à l'extrémité arrière de cet accumulateur haute pression 33, en y étant disposé sensiblement transversalement.  The pressure accumulators 33, 34 each constitute an elongated tube of reduced circular section, which is favorable for limiting the stresses in this accumulator. The high pressure accumulator 33 is disposed under the underbase 50 of the vehicle, longitudinally in the axis XX 'of this vehicle. The low pressure accumulator 34 is fixed rigidly to the rear end of this high pressure accumulator 33, being disposed substantially transversely thereto.
De plus, ce sous-ensemble hydraulique présentant une forme générale en « T », comporte avantageusement une partie longitudinale disposée sous le sous-bassement, dans un tunnel longitudinal 52, et une partie transversale disposée dans un creux transversal 54 disponible sous les sièges prévus pour des passagers arrière du véhicule. Ce type de tunnel est souvent prévu dans certains véhicules pour recevoir un tube d'échappement et ce type de creux transversal est souvent prévu dans certains véhicules pour recevoir un réservoir à carburant. In addition, this hydraulic subassembly having a general shape in "T", advantageously comprises a longitudinal portion disposed under the underbase, in a longitudinal tunnel 52, and a transverse portion disposed in a transverse recess 54 available under the seats provided for rear passengers of the vehicle. This type of tunnel is often provided in certain vehicles to receive an exhaust pipe and this type of transverse recess is often provided in certain vehicles to receive a fuel tank.
Dans cette implantation, la ligne d'échappement (non représentée passe en dehors du tunnel pour laisser place à l'accumulateur haute pression.  In this implementation, the exhaust line (not shown goes outside the tunnel to make room for the high pressure accumulator.
La machine hydraulique reliée à des roues motrices (non représentées), peut fonctionner en moteur pour délivrer une puissance mécanique à ces roues motrices en prélevant de l'énergie stockée dans les accumulateurs de pression, ou en pompe pour charger ces accumulateurs en freinant le véhicule, de manière à récupérer l'énergie cinétique de ce véhicule.  The hydraulic machine connected to driving wheels (not shown), can operate as a motor to deliver mechanical power to these driving wheels by drawing energy stored in the pressure accumulators, or as a pump for charging these accumulators by braking the vehicle , so as to recover the kinetic energy of this vehicle.
Cette utilisation d'énergie hydraulique stockée permet d'optimiser le fonctionnement du moteur thermique 30, et de réduire sa consommation ainsi que les émissions de gaz polluants. Le stockage d'énergie hydraulique permet de plus de rouler en mode hydraulique avec zéro émission, appelé mode « ZEV », le moteur thermique restant à l'arrêt.  This use of stored hydraulic energy makes it possible to optimize the operation of the heat engine 30, and to reduce its consumption as well as the emissions of gaseous pollutants. Hydraulic energy storage also makes it possible to drive in hydraulic mode with zero emissions, called "ZEV" mode, the heat engine remaining at a standstill.
Lorsque le véhicule roule en mode hydraulique pur « ZEV » et donc moteur thermique arrêté, l'alimentation électrique du réseau de bord doit continuer à être assurée en toute transparence vis-à-vis du conducteur et des passagers du véhicule (confort).  When the vehicle is driven in pure hydraulic mode "ZEV" and thus the engine stopped, the power supply of the on-board electrical system must continue to be ensured in a transparent manner with respect to the driver and passengers of the vehicle (comfort).
Les stockeurs d'énergie électrique tels que les batteries au plomb traditionnellement utilisées pour fournir du courant au réseau de bord, ne sont pas adaptées au fonctionnement des véhicules hybrides hydrauliques dont le fonctionnement en mode impulsionnel sollicite la batterie sur des cycles de charges et de décharges très courts et répétés , ce qui tend à détériorer les batteries très rapidement (vieillissement prématuré).  Electrical energy storage systems, such as lead-acid batteries traditionally used to supply power to the on-board electrical system, are not adapted to the operation of hydraulic hybrid vehicles whose operation in pulsed mode requires the battery on charge and discharge cycles. very short and repeated, which tends to deteriorate the batteries very quickly (premature aging).
Par mode impulsionnel, on entend un mode de fonctionnement dans lequel le moteur thermique, bien que non utilisé pour la traction du véhicule, est sollicité pendant une période très courte et de manière répétée, pour pouvoir activer la pompe hydraulique destinée à maintenir une pression suffisante dans les accumulateurs de pression.  Pulse mode means a mode of operation in which the engine, although not used for traction of the vehicle, is solicited for a very short period and repeatedly, to be able to activate the hydraulic pump to maintain sufficient pressure in pressure accumulators.
II est connu de la demande de brevet n ° 1 161716, déposée par la demanderesse, un véhicule hybride hydraulique comprenant un stockeur d'énergie électrique pour alimenter le réseau électrique de bord quand le moteur thermique est arrêté. Ce stockeur se charge et se décharge très rapidement en acceptant des courants élevés, sans détériorer le cyclage batterie et donc sa durée de vie. Il est implanté sous le sous-bassement du véhicule et est supporté par un des accumulateurs hydrauliques qui est également implanté sous le sous-bassement du véhicule. It is known from patent application No. 1 161716, filed by the applicant, a hydraulic hybrid vehicle comprising a storer of electrical energy to supply the electrical network on board when the thermal engine is stopped. This storage unit charges and discharges very quickly by accepting high currents, without damaging battery cycling and therefore its service life. It is implanted under the underbase of the vehicle and is supported by one of the hydraulic accumulators which is also implanted under the underbase of the vehicle.
Ce type de stockeur nécessite un boîtier de pilotage dédié pour piloter l'énergie stockée.  This type of storage requires a dedicated control box to control the stored energy.
Ce boîtier comprend des composants électroniques de puissance qui chauffent, qui sont sensibles au choc et qui sont de plus sensibles à la température environnante.  This housing includes power electronics that heat, which are sensitive to shock and are more sensitive to the surrounding temperature.

Le véhicule est caractérisé en ce qu'il comprend un boîtier de pilotage de la charge du stockeur d'énergie électrique, disposé de l'autre côté du sous- bassement, dans l'habitacle, à proximité immédiate du stockeur ; le boîtier de pilotage étant relié au stockeur par un faisceau de câbles électriques traversant le sous-bassement.  The vehicle is characterized in that it comprises a load control casing of the electrical energy store, disposed on the other side of the underbase, in the passenger compartment, in the immediate vicinity of the storeroom; the control box being connected to the storer by a bundle of electrical cables passing through the underbase.

Selon une autre caractéristique, le boîtier de pilotage, disposé dans l'habitacle du véhicule, est relié au stockeur d'énergie par le faisceau de câbles électriques passant au travers d'un orifice managé dans le sous- bassement. Selon une autre caractéristique, l'orifice de passage du faisceau de câbles électriques correspond à l'orifice de traversée des câbles de pilotage d'une boîte de vitesses ; ladite traversée étant initialement prévue pour un véhicule équipé d'une boîte de vitesses manuelle. According to another characteristic, the control unit, disposed in the passenger compartment of the vehicle, is connected to the energy store by the bundle of electric cables passing through a managed port in the underbase. According to another characteristic, the passage opening of the electrical cable bundle corresponds to the through hole of the control cables of a gearbox; said crossing being initially provided for a vehicle equipped with a manual gearbox.

Un avantage de l'implantation du boîtier de pilotage dans l'habitacle à proximité du stockeur est que la température est régulée par le système de climatisation de l'habitacle tout en étant protégé contre les chocs divers.  An advantage of the implementation of the control box in the passenger compartment near the storer is that the temperature is regulated by the air conditioning system of the passenger compartment while being protected against various shocks.
Un autre avantage est l'intégration optimale du boîtier dans l'habitacle d'un véhicule sans modification de sa structure ni de ses équipements.  Another advantage is the optimal integration of the housing in the passenger compartment of a vehicle without modifying its structure or its equipment.

Sur les figures, les éléments communs avec ceux de la figure 1 (état de la technique) sont désignés, respectivement, par les mêmes références numériques. In the figures, the reference XYZ has been made which is usually used to position a vehicle in space. In the figures, the elements common with those of Figure 1 (state of the art) are designated, respectively, by the same reference numerals.
Un boîtier de pilotage 40 illustrée à la figure 5, présente la forme générale d'un parallélépipède rectangle comportant une embase ou platine de fixation 41 , et un connecteur électrique 42 faisant saillie d'une des faces latérale du boîtier.  A control box 40 illustrated in Figure 5, has the general shape of a rectangular parallelepiped comprising a base or mounting plate 41, and an electrical connector 42 projecting from one of the side faces of the housing.
Ce type de boîtier de pilotage est connu. Il comprend des composants électroniques de puissance (redresseur, convertisseur, ..) aptes à adapter les courants délivrés par les stockeurs et notamment les UCAPs au réseau électrique de bord tout en sécurisant ce même réseau.  This type of control box is known. It includes electronic power components (rectifier, converter, ..) adapted to adapt the currents delivered by the storage and including the UCAPs to the on-board electrical network while securing the same network.
Le boîtier est disposé à l'intérieur de l'habitacle du véhicule (fig. 2 et 3) dans une zone correspondant à la console centrale 44 qui est située entre les deux sièges avant. C'est dans cette zone que se situe généralement le frein de stationnement du véhicule manuel ou électrique.  The housing is disposed within the passenger compartment of the vehicle (Figures 2 and 3) in an area corresponding to the center console 44 which is located between the two front seats. It is in this area that the parking brake of the manual or electric vehicle is usually located.
Dans l'exemple décrit, le boîtier repose sur, ou au voisinage du, plancher du véhicule par une de ses face latérales de telle manière que le connecteur électrique du boîtier soit orienté vers l'avant du véhicule.  In the example described, the housing rests on or near the floor of the vehicle by one of its side faces so that the electrical connector of the housing is oriented towards the front of the vehicle.
Le boîtier est ainsi complètement intégré dans la console sans nécessiter de modification de l'aspect extérieur de la console.  The case is thus completely integrated in the console without requiring modification of the external appearance of the console.
La platine de fixation est disposée dans un plan vertical parallèle au plan médian de la console centrale.  The mounting plate is arranged in a vertical plane parallel to the median plane of the central console.
Sa fixation est faite dans la console centrale.  Its fixation is made in the central console.

Tout comme le boîtier, le faisceau est invisible du conducteur car il est caché par la console.  Like the case, the beam is invisible to the driver because it is hidden by the console.
Un orifice 46 est managé dans le plancher et le sous-bassement du véhicule de manière à définir un passage, ou traversée, pour le faisceau entre le boîtier et le stockeur.  An orifice 46 is managed in the floor and under-basing of the vehicle so as to define a passage, or crossing, for the beam between the housing and the storer.
Cette traversée peut correspondre avantageusement à la traversée habituellement prévue pour le passage des câbles de pilotage d'une boîte de vitesses quand le véhicule en est dépourvu.  This crossing may advantageously correspond to the crossing usually provided for the passage of the control cables of a gearbox when the vehicle is devoid of it.
Le stockeur 20 comporte un boîtier étanche 21 -22 renfermant quatre UCAPs 23-1 à 23-4 de forme générale cylindrique dans l'exemple décrit en référence à la figure 4.  The storer 20 comprises a sealed housing 21 -22 enclosing four UCAPs 23-1 to 23-4 of generally cylindrical shape in the example described with reference to FIG. 4.
Le boîtier du stockeur comprend deux parties 21 , 22 présentant chacune une forme générale d'un parallélépipède rectangle.  The storage casing comprises two parts 21, 22 each having a general shape of a rectangular parallelepiped.
Les deux parties sont imbriquées l'une dans l'autre par une de leurs faces latérales et une partie est inclinée par rapport à l'autre d'un angle déterminé.  The two parts are nested one inside the other by one of their lateral faces and one part is inclined relative to the other by a determined angle.
La partie destinée à être positionnée sur l'accumulateur haute pression, désignée par partie inférieure 21 , supporte sur sa face latérale orientée vers l'arrière du véhicule, le connecteur électrique recevant la deuxième extrémité du faisceau du câble électrique.  The portion intended to be positioned on the high pressure accumulator, designated lower part 21, supports on its lateral face facing the rear of the vehicle, the electrical connector receiving the second end of the bundle of the electric cable.
Le boîtier est monté dans le véhicule après l'opération de coiffage de la caisse sur le sous-bassement, et le faisceau de câbles est ensuite monté en faisant passer le faisceau par la traversée.  The housing is mounted in the vehicle after the styling operation of the body on the underbase, and the wiring harness is then mounted by passing the beam through the bushing.
L'implantation du boîtier de pilotage dans l'habitacle, au-dessus, de la traversée de câbles de pilotage de boîte de vitesses, permet avantageusement de libérer de la place dans le bloc moteur (déjà très contraint) et de limiter la longueur du faisceau de câbles : la longueur du faisceau ayant un impact sur le coût.  The implementation of the control box in the cabin, above, the crossing of transmission control cables, advantageously allows to free up space in the engine block (already very constrained) and limit the length of the wire bundle: the length of the bundle has an impact on the cost.
