Description

VEHICULE AUTOMOBILE COMPRENANT UN SYSTEME DE GESTION D’AUTONOMIE RESTANTEMOTOR VEHICLE COMPRISING A REMAINING AUTONOMY MANAGEMENT SYSTEM

La présente invention concerne le domaine des véhicules automobiles à moteur à combustion. Plus particulièrement, l’invention a pour objet un véhicule automobile comprenant un système de gestion d’autonomie restante.The present invention relates to the field of combustion engine motor vehicles. More particularly, the subject of the invention is a motor vehicle comprising a remaining range management system.

Les véhicules automobiles équipés de moteur à combustion sont également équipés d’une indication du niveau de carburant contenu dans leur réservoir de carburant. Classiquement, lorsque le niveau de carburant au réservoir arrive à un certain niveau faible, un voyant s’active. L’activation de ce voyant peut s’accompagner d’un son d’alerte.Motor vehicles equipped with a combustion engine are also equipped with an indication of the level of fuel contained in their fuel tank. Conventionally, when the fuel level in the tank reaches a certain low level, a warning light is activated. The activation of this light may be accompanied by an alert sound.

Cette solution est passive, elle renseigne uniquement le conducteur du niveau faible du carburant et l’avertit d’un risque de panne sèche.This solution is passive, it only informs the driver of the low fuel level and warns him of a risk of running out of fuel.

Il est connu, par exemple du document FR2994152A1, pour les motorisations électriques un mode électrique faiblement dégradé, appelé par certains constructeurs « mode tortue ». Dans ce mode électrique faiblement dégradé, la motorisation électrique délivre un couple réduit afin d'économiser l'énergie électrique, et d'obtenir une certaine autonomie restante du véhicule, lorsque le niveau de charge de la batterie alimentant le moteur électrique est en dessous d’un niveau critique. Cependant cette limitation peut ne pas être suffisante pour éviter le risque de panne du véhicule ou rassurer le conducteur.It is known, for example from document FR2994152A1, for electric motors a slightly degraded electric mode, called by certain manufacturers “tortoise mode”. In this slightly degraded electric mode, the electric motor delivers a reduced torque in order to save electric energy, and to obtain a certain remaining range of the vehicle, when the level of charge of the battery supplying the electric motor is below a critical level. However, this limitation may not be sufficient to avoid the risk of breakdown of the vehicle or to reassure the driver.

Il existe donc un besoin pour améliorer les inconvénients précités. Pour atteindre cet objectif, il est prévu selon l’invention un véhicule automobile comprenant un moteur de traction alimenté par une réserve d’énergie, un système de gestion de l’autonomie restante dans lequel le moteur de traction délivre un couple réduit lorsque cette réserve d’énergie franchit à la baisse un seuil critique, caractérisé en ce que le système de gestion comprend une interface pour permettre à un utilisateur de régler ce seuil critique.There is therefore a need to improve the aforementioned drawbacks. To achieve this objective, provision is made according to the invention for a motor vehicle comprising a traction motor powered by an energy reserve, a system for managing the remaining autonomy in which the traction motor delivers a reduced torque when this reserve of energy falls below a critical threshold, characterized in that the management system comprises an interface to allow a user to adjust this critical threshold.

L’effet technique est d’obtenir une économie d’énergie personnalisable par le conducteur, ce qui permet de mieux maitriser la situation de risque de panne sèche.The technical effect is to obtain an energy saving that can be personalized by the driver, which makes it possible to better control the risk of running out of fuel.

Diverses caractéristiques supplémentaires peuvent être prévues, seules ou en combinaisons :Various additional features may be provided, alone or in combination:

Selon une réalisation, l’interface comprend des moyens de réglage et de visualisation d’un seuil critique de distance.According to one embodiment, the interface comprises means for setting and displaying a critical distance threshold.

Selon une réalisation, le moteur de traction est un moteur à combustion interne et la réserve d’énergie est une quantité de carburant.According to one embodiment, the traction motor is an internal combustion engine and the energy reserve is a quantity of fuel.

Selon une réalisation, le véhicule comprend de plus une boite de vitesses pilotée et le système de gestion comprend des moyens de limitation du couple moteur sous un seuil de couple maximum ainsi que des moyens d’optimisation des transitions entre rapports de boite de vitesses agencés pour rester au mieux dans une plage de régime de fonctionnement encadrant une zone de consommation minimale (Zcm) prédéterminée.According to one embodiment, the vehicle also comprises a controlled gearbox and the management system comprises means for limiting the engine torque below a maximum torque threshold as well as means for optimizing the transitions between gearbox ratios arranged to remain at best within an operating speed range bordering a predetermined minimum consumption zone (Zcm).

D’autres particularités et avantages apparaîtront à la lecture de la description ci-après d’un mode particulier de réalisation, non limitatif de l’invention, faite en référence aux figures dans lesquelles :Other features and advantages will appear on reading the description below of a particular, non-limiting embodiment of the invention, made with reference to the figures in which:

Cette figure représente schématiquement le système de gestion de l’autonomie restante d’un véhicule selon l’invention. This figure schematically represents the system for managing the remaining autonomy of a vehicle according to the invention.

Cette figure représente un graphe montrant en fonction du couple moteur T et du régime N des courbes d’iso consommation. This figure represents a graph showing iso-consumption curves as a function of the engine torque T and of the speed N.

La représente un exemple de système de gestion de l’autonomie restante d’un véhicule automobile. Le véhicule est équipé d’un moteur à combustion interne 9 alimenté en carburant, à partir d’une réserve de carburant (non représentée). Le véhicule peut être équipé d’une boite de vitesse pilotée,10.There represents an example of a system for managing the remaining autonomy of a motor vehicle. The vehicle is equipped with an internal combustion engine 9 supplied with fuel from a fuel reserve (not shown). The vehicle may be equipped with a controlled gearbox,10.

Ce système comprend une interface utilisateur, I. Cette interface utilisateur, I, peut-être une interface graphique avec des moyens de visualisation de réglage et de visualisation 1a d’un seuil critique, Sc. L’interface utilisateur, I, peut comprendre des moyens de validation, 1b, ou de refus, 1c, d’application d’un mode de fonctionnement spécifique dit « mode tortue » dans lequel le moteur de traction 9 délivre un couple moteur réduit lorsque cette réserve d’énergie franchit à la baisse le seuil critique Sc. Ainsi, l’utilisateur a la possibilité de régler le niveau minimal de carburant qui conditionne le passage à ce mode de fonctionnement spécifique.This system comprises a user interface, I. This user interface, I, can be a graphic interface with means for displaying adjustment and display 1a of a critical threshold, Sc. The user interface, I, can comprise means for validating, 1b, or refusing, 1c, the application of a specific mode of operation called "tortoise mode" in which the traction motor 9 delivers a reduced motor torque when this reserve of energy crosses downward the critical threshold Sc. Thus, the user has the possibility of adjusting the minimum level of fuel which conditions the passage to this specific operating mode.

L’utilisateur peut régler un seuil critique Sc de distance, par exemple de 50 km. Le système comprend un module de conversion 2, qui convertit la distance Sc réglée par l’utilisateur en un seuil Sc’ de quantité de carburant. Pour plus de précision, ce module 2 de conversion peut estimer le seuil Sc’ de quantité de carburant en fonction du type de carburant présent dans le réservoir.The user can set a critical distance threshold Sc, for example 50 km. The system comprises a conversion module 2, which converts the distance Sc set by the user into a fuel quantity threshold Sc'. For greater accuracy, this conversion module 2 can estimate the fuel quantity threshold Sc' as a function of the type of fuel present in the tank.

Un module 3 de décision d’activation du mode « tortue » compare ensuite ce seuil Sc’ avec une information J en provenance d’une jauge de carburant sur la quantité restante de carburant et décide de l’application de ce mode de fonctionnement « tortue » si quantité restante de carburant est inférieur au seuil Sc’ de quantité de carburant.A “turtle” mode activation decision module 3 then compares this threshold Sc′ with information J from a fuel gauge on the remaining quantity of fuel and decides on the application of this “turtle” mode of operation if the remaining amount of fuel is less than the fuel amount threshold Sc'.

Dans l’affirmative, (branche Y quittant le module 3), des cartographies spécifiques de fonctionnement du moteur 9 et de la boite de vitesse 10 sont sélectionnées (modules 4 et 5) et transférés (module 6) vers un calculateur 7 responsable du moteur et un calculateur 8 responsable des passages des rapports de la boite vitesse. Le calculateur 7 responsable du moteur limite le couple moteur produit en sortie de l'arbre du moteur 9.If so, (branch Y leaving module 3), specific operating maps of engine 9 and gearbox 10 are selected (modules 4 and 5) and transferred (module 6) to a computer 7 responsible for the engine and a computer 8 responsible for the gearshifts of the gearbox. The computer 7 responsible for the engine limits the engine torque produced at the output of the shaft of the engine 9.

Comme le montre la , le couple moteur peut être limité à un couple moteur maximum, Tmax.As shown in , the motor torque can be limited to a maximum motor torque, Tmax.

Le calculateur 8 responsable des passages des rapports de la boite vitesses comprend des moyens d’optimisation du choix du point de transition entre les rapports de la boite de vitesses 10 afin de rester au mieux dans une plage P de régime N de fonctionnement encadrant une zone de consommation minimale Zcm prédéterminée ( ). Ceci permet de minimiser la consommation de carburant.The computer 8 responsible for the gear changes of the gearbox comprises means for optimizing the choice of the transition point between the gear ratios of the gearbox 10 in order to remain as well as possible within a range P of operating speed N surrounding a zone predetermined minimum consumption Zcm ( ). This minimizes fuel consumption.

Les différents modules de traitement décrits peuvent être compris dans un calculateur de contrôle du moteur 9.The various processing modules described can be included in an engine control computer 9.

L’invention ne se limite pas au mode de réalisation décrit. En variante, le moteur de traction peut être un moteur électrique. Dans ce cas, un tel moteur est alimenté par une réserve d’énergie électrique contenue dans une batterie de traction et le système de gestion de l’autonomie restante convertit alors le seuil critique de distance défini dans l’interface, I, en niveau de charge critique de la batterie.The invention is not limited to the embodiment described. Alternatively, the traction motor may be an electric motor. In this case, such a motor is powered by a reserve of electrical energy contained in a traction battery and the remaining range management system then converts the critical distance threshold defined in the interface, I, into a level of critical battery charge.

Cette solution permet au conducteur de gagner plus de temps et de ressources grâce à l’économie d’énergie personnalisable proposée par cette invention. Ainsi, grâce à la limitation de couple de traction fournie par le moteur thermique il aura plus de chance d’éviter une panne sèche au milieu de ses roulages. Le conducteur se sent ainsi mieux protégé et plus en sécurité face au risque de panne sèche.This solution allows the driver to save more time and resources thanks to the customizable energy saving offered by this invention. Thus, thanks to the traction torque limitation provided by the internal combustion engine, it will have a better chance of avoiding a dry breakdown in the middle of its travels. The driver thus feels better protected and safer against the risk of running out of fuel.
