L'invention sera mieux comprise à la lecture de la description qui suit et à l'examen des figures qui l'accompagnent. Ces figures ne sont données qu'à titre
illustratif et nullement limitatif de l'invention. Elles montrent : figure 1 : une représentation schématique des éléments essentiels d'un véhicule hybride pour mettre en œuvre 1 ' invention ;The invention will be better understood on reading the description which follows and on examining the figures which accompany it. These figures are given only as illustrative and not limiting of the invention. They show: FIG. 1: a schematic representation of the essential elements of a hybrid vehicle for implementing the invention;
- figure 2 : un logigramme montrant des étapes de procédé conformes à l'invention.FIG. 2: a logic diagram showing process steps in accordance with the invention.
Les éléments identiques conservent la même référence d'une figure à l'autre. En référence à la figure 1, un véhicule hybride comprend un stockeur électrique 11 constitué d'une batterie, de super capacités ou de tout autre élément apte à stocker de façon réversible de l'énergie électrique. Divers consommateurs électriques 21 tels que les phares d'éclairage, les éléments de chauffage et de climatisation du véhicule, les organes de pilotage de la boîte de vitesses, sont branchés aux bornes du stockeur électrique 11 et consomment l'énergie électrique dont ils ont besoin au moment opportun. Un convertisseur 50 réversible d'énergie électrique en énergie mécanique consomme de l'énergie électrique fournie par le stockeur électrique dans différents cas de vie. Lorsque la force motrice du véhicule est fournie par un moteur thermique, le stockeur électrique peut apporter un complément d'énergie pour améliorer les performances, par exemple en cas d'une demande de surcharge énergétique que l'on peut nommer boost pour la circonstance en hommage au terme en langue étrangère de signification identique pour accélérer le véhicule. Le convertisseur réversible 50 fournit de l'énergie au stockeur électrique notamment lorsque le véhicule est en décélération ou en pente descendante, mais cela ne suffit pas nécessairement à assurer un bilan énergétique nul. Le convertisseur réversible 50 doit aussi fournir de l'énergie électrique pour recharger le stockeur électrique 11 à d'autres moments en mettant à contribution le moteur thermique.
Le convertisseur réversible 50 comprend une borne 51 reliée au pôle positif du stockeur électrique 11 et une borne 52 reliée au pôle négatif du stockeur électrique 11. Entre les bornes 51 et 52, le convertisseur réversible 50 comprend par exemple une machine électrique 53 qui fournit de l'énergie mécanique en mode moteur lorsque le convertisseur réversible 50 est commandé par un élément de signal 41 et absorbe de l'énergie mécanique en mode génératrice pour charger le stockeur électrique 11 lorsque le convertisseur réversible 50 est commandé par un élément de signal 42. Les éléments de signaux 41 et 42 sont générés par un module généralement électronique 40. Le module 40 établit les valeurs des éléments de signaux 41 et 42 en fonction d'une consigne de couple à fournir ou à absorber par la machine électrique 53. Pour ce faire, le module 40 reçoit diverses commandes, par exemple des unités de freinage ou des unités d'accélération du véhicule ou encore d'un module généralement électronique 30 qui est agencé pour recevoir un niveau de charge du stockeur 11 depuis un capteur 31 qui, de façon connue, mesure la tension aux bornes du stockeur électrique 11 et estime son impédance à partir d'un courant électrique traversant le stockeur électrique 11. Le module 40 reçoit plus particulièrement un signal 61 de contrôle commande d'un module généralement électronique 60. Le module 60 est agencé pour autoriser de manière contrôlée une décharge du stockeur. Comme nous allons le voir dans la suite de la description, le signal 61 contient une consigne d'énergie ou de puissance à consommer par le convertisseur réversible 50 à partir du stockeur 11 suite à une demande de complément énergétique, reçue par un signal 63, pour augmenter les performances du véhicule ou à une demande d'énergie utilisable, reçue par un signal 62, pour optimiser la consommation énergétique du véhicule.Identical elements retain the same reference from one figure to another. With reference to FIG. 1, a hybrid vehicle comprises an electrical storage unit 11 consisting of a battery, super capacitors or any other element capable of reversibly storing electrical energy. Various electrical consumers 21 such as the lighting headlights, the heating and air conditioning elements of the vehicle, the control members of the gearbox, are connected to the terminals of the electric storage unit 11 and consume the electrical energy they need. timely. A reversible converter 50 of electrical energy into mechanical energy consumes electrical energy supplied by the electrical storer in different life situations. When the driving force of the vehicle is provided by a heat engine, the electric storage can provide additional energy to improve performance, for example in the case of a request for energy surcharge that can be called boost for the circumstance in question. homage to the term in foreign language of identical meaning to accelerate the vehicle. The reversible converter 50 supplies energy to the electrical storer especially when the vehicle is decelerating or downhill, but this is not necessarily sufficient to ensure a zero energy balance. The reversible converter 50 must also provide electrical energy to recharge the electric storage 11 at other times by using the engine. The reversible converter 50 comprises a terminal 51 connected to the positive pole of the electrical storage unit 11 and a terminal 52 connected to the negative pole of the electrical storage unit 11. Between the terminals 51 and 52, the reversible converter 50 comprises for example an electric machine 53 which provides the mechanical energy in motor mode when the reversible converter 50 is controlled by a signal element 41 and absorbs mechanical energy in generator mode to charge the electric storage unit 11 when the reversible converter 50 is controlled by a signal element 42. The signal elements 41 and 42 are generated by a generally electronic module 40. The module 40 establishes the values of the signal elements 41 and 42 as a function of a torque setpoint to be supplied or absorbed by the electric machine 53. the module 40 receives various commands, for example braking units or vehicle acceleration units or a generally electronic module 30 which is arranged to receive a charge level of the storage unit 11 from a sensor 31 which, in a known manner, measures the voltage across the electrical storage unit 11 and estimates its impedance from a current The module 40 more particularly receives a control signal 61 from a generally electronic module 60. The module 60 is arranged to authorize in a controlled manner a discharge of the storage device. As will be seen in the remainder of the description, the signal 61 contains a setpoint of energy or power to be consumed by the reversible converter 50 from the storage unit 11 following a request for an energy supplement received by a signal 63. to increase the performance of the vehicle or a usable energy demand, received by a signal 62, to optimize the energy consumption of the vehicle.
Une augmentation de performance, par exemple en accélération, consiste généralement à ajouter le couple
de la machine électrique au couple du moteur thermique et pousser ainsi l'accélération. Une optimisation de la consommation énergétique du véhicule, par exemple à faible vitesse de déplacement, consiste généralement à utiliser principalement le couple de la machine électrique en allant jusqu'à arrêter le moteur thermique de façon à baisser la consommation de carburant.An increase in performance, for example in acceleration, usually consists of adding the couple from the electric machine to the torque of the engine and thus push the acceleration. An optimization of the energy consumption of the vehicle, for example at low speed of travel, generally consists in using mainly the torque of the electric machine, even stopping the heat engine so as to lower the fuel consumption.
Le module 60 est agencé, par exemple au moyen d'un microprocesseur et d'une mémoire numérique ou analogique, pour exécuter le procédé expliqué à présent en référence à la figure 2.The module 60 is arranged, for example by means of a microprocessor and a digital or analog memory, to execute the method explained now with reference to FIG. 2.
En référence à la figure 2, le procédé de contrôle comprend une première étape 806 ordonnancée de façon à autoriser une décharge du stockeur lorsque l'une des trois transitions suivantes est validée.With reference to FIG. 2, the control method comprises a first step 806 that is sequenced so as to authorize a discharge of the storer when one of the following three transitions is validated.
Une transition 805 est validée sur détection d'un état de charge du stockeur supérieur à un premier seuil Lv qui est la limite basse d'une plage verte d'énergie plus particulièrement dimensionnée pour optimiser une consommation énergétique du véhicule, par exemple à faible vitesse de croisière ou en cycle urbain.A transition 805 is validated on detection of a state of charge of the storer higher than a first threshold Lv which is the low limit of a green range of energy more particularly dimensioned to optimize an energy consumption of the vehicle, for example at low speed cruise or urban cycle.
Une transition 811 est validée sur détection d'un état de charge du stockeur supérieur à un deuxième seuil Lr qui est la limite basse d'une plage orange d'énergie plus particulièrement dimensionnée pour augmenter une performance du véhicule, par exemple en accélération.A transition 811 is validated on detecting a state of charge of the storer greater than a second threshold Lr which is the low limit of an orange range of energy more particularly dimensioned to increase a vehicle performance, for example in acceleration.
Une transition 813 est validée par une demande d'énergie de compensation de transitoires. La validation de cette transition n'est pas nécessairement liée à une détection logique mais peut résulter naturellement d'un phénomène transitoire. Le deuxième seuil Lr est aussi la limite haute d'une plage rouge d'énergie minimale plus particulièrement dimensionnée de manière à Cβ que sa quantité d'énergie soit rapidement remboursable en cas de diminution, par de la recharge directe via le moteur thermique ou par de la récupération sur une faible décélération .
Sa taille détermine les performances dynamiques minimales garanties du véhicule.A transition 813 is enabled by a transient compensation energy request. The validation of this transition is not necessarily linked to a logical detection but can result naturally from a transient phenomenon. The second threshold Lr is also the upper limit of a red minimum energy range more particularly dimensioned so as to Cβ that its energy quantity is quickly refundable in case of reduction, by direct charging via the engine or by recovery on a slow deceleration. Its size determines the guaranteed minimum dynamic performance of the vehicle.
La pérennité de son énergie repose sur une énergie inaccessible à la stratégie d'optimisation de la consommation, une recharge prioritaire par rapport à la plage verte, un transvasement de l'énergie d'optimisation de la consommation lorsque celle-ci est disponible et une quantité d'énergie facilement remboursable par construction. Dans ce but, le deuxième seuil est fixé à une valeur d'énergie minimale réservée à une compensation de transitoires.The durability of its energy is based on an energy that is inaccessible to the strategy of optimizing consumption, a priority recharge compared to the green beach, a transfer of energy consumption optimization when it is available and a amount of energy easily reimbursable by construction. For this purpose, the second threshold is set to a minimum energy value reserved for transient compensation.
Le premier seuil qui est la limite basse de la plage verte, est aussi la limite haute de la plage orange. En le rendant paramétrable ou fonction de conditions de vie du véhicule, le premier seuil délimite une plage d'énergie de hauteur variable au dessus du deuxième seuil.The first threshold, which is the lower limit of the green beach, is also the upper limit of the orange beach. By making it configurable or function of vehicle life conditions, the first threshold delimits an energy range of variable height above the second threshold.
La transition 805 est validée à la suite d'une étape 802 qui mesure le niveau ou état de charge du stockeur SOC (acronyme de l'expression étrangère State OfThe transition 805 is validated following a step 802 which measures the level or state of charge of the SOC storer (acronym for the foreign expression State Of
Charge) lorsqu'une demande d'optimisation de consommation valide une transition 801.Load) when a consumption optimization request validates a transition 801.
Une transition 803 est validée à la suite de l'étape 802 lorsque le niveau ou état de charge du stockeur SOC est inférieur ou égal au seuil Lv, de façon à activer une étape 804 qui interdit alors de décharger le stockeur pour optimiser la consommation énergétique du véhicule .A transition 803 is validated following step 802 when the level or state of charge of the SOC storer is less than or equal to the threshold Lv, so as to activate a step 804 which then forbids unloading the storer to optimize the energy consumption of the vehicle .
La transition 811 est validée à la suite d'une étape 808 qui mesure le niveau ou état de charge du stockeur SOC lorsqu'une demande d'augmentation de performance valide une transition 807.The transition 811 is validated following a step 808 which measures the level or state of charge of the SOC storer when a request for a performance increase validates an 807 transition.
Une transition 809 est validée à la suite de l'étape 808 lorsque le niveau ou état de charge du stockeur SOC est inférieur ou égal au seuil Lr, de façon à activer une étape 810 qui interdit alors de décharger le stockeur pour augmenter la performance du véhicule.
