Description
L’invention se rapporte au domaine des véhicules automobiles comportant un système de transmission équipé d’un dispositif de blocage en stationnement.The invention relates to the field of motor vehicles comprising a transmission system equipped with a parking locking device.
Les systèmes de transmission des véhicules électriques sont équipés d’un dispositif de blocage permettant de bloquer et maintenir le véhicule automobile en stationnement.The transmission systems of electric vehicles are equipped with a blocking device allowing the motor vehicle to be blocked and kept parked.
Ce dispositif de blocage est automatiquement enclenché lorsque, par exemple, le conducteur sort de son véhicule, et le contact avec le moteur est coupé.This blocking device is automatically engaged when, for example, the driver gets out of his vehicle, and contact with the engine is cut.
Il existe cependant des moyens dépendant de chaque constructeur qui permettent de passer outre ce dispositif. En effet, il doit être possible pour un client de placer le véhicule "en roue libre", notamment dans deux cas connus de l'homme de l'art :
- un conducteur veut déplacer son véhicule dans son garage de quelques dizaines de cm ; et
- une station de lavage dont le système tracte le véhicule.However, there are ways depending on each manufacturer that allow you to override this device. Indeed, it must be possible for a customer to place the vehicle "freewheeling", particularly in two cases known to those skilled in the art:
- a driver wants to move his vehicle in his garage by a few tens of cm; And
- a washing station whose system tows the vehicle.
L’objectif de l’invention est de remédier aux défauts de l’art antérieur, et notamment de proposer une solution de passage en roue libre pour des véhicules équipés d’un dispositif de blocage en stationnement.The objective of the invention is to remedy the defects of the prior art, and in particular to propose a freewheeling solution for vehicles equipped with a parking locking device.
Pour atteindre cet objectif, l’invention propose un véhicule automobile comprenant :
- une batterie de traction, et une batterie accessoire pour des dispositifs accessoire du véhicule ;
- une boîte de vitesse ;
- un système de transmission équipé d’un dispositif de blocage pour bloquer le véhicule automobile en stationnement ;
caractérisé en ce que le véhicule automobile comprend en outre un système électronique comprenant un convertisseur DCDC connectant la batterie de traction à la batterie accessoire, et un système de mise en roue libre pour mettre le véhicule automobile en roue libre lorsque le dispositif de blocage bloque le véhicule automobile en stationnement, le système de mise en roue libre comprenant :
- un moyen de déblocage pour désactiver le dispositif de blocage, le moyen de déblocage étant alimenté par la batterie accessoire,
- un contrôleur déterminant et comparant l’énergie disponible de la batterie accessoire sur la base de l’état de charge, et le besoin énergétique pour la mise en œuvre du moyen de déblocage,
et en ce que le contrôleur autorise la mise en œuvre du moyen de déblocage si ladite énergie disponible est supérieure audit besoin énergétique ; ou déclenche un transfert d’énergie de la batterie de traction vers la batterie accessoire de sorte que ladite énergie disponible soit supérieure audit besoin énergétique, et ensuite autorise la mise en œuvre du moyen de déblocage.To achieve this objective, the invention proposes a motor vehicle comprising:
- a traction battery, and an accessory battery for vehicle accessory devices;
- a gearbox;
- a transmission system equipped with a blocking device for blocking the parked motor vehicle;
characterized in that the motor vehicle further comprises an electronic system comprising a DCDC converter connecting the traction battery to the accessory battery, and a freewheeling system for freewheeling the motor vehicle when the blocking device blocks the parked motor vehicle, the freewheeling system comprising:
- an unlocking means for deactivating the blocking device, the unlocking means being powered by the accessory battery,
- a controller determining and comparing the available energy of the accessory battery on the basis of the state of charge, and the energy requirement for implementing the unlocking means,
and in that the controller authorizes the implementation of the unlocking means if said available energy is greater than said energy requirement; or triggers a transfer of energy from the traction battery to the accessory battery so that said available energy is greater than said energy requirement, and then authorizes the implementation of the unlocking means.
En particulier, le système de mise en roue libre est en fait le désarmement du dispositif de blocage. En général, le dispositif de blocage est actif lorsqu’il est alimenté et se désengage automatiquement lorsqu’il ne l’est plus.In particular, the freewheeling system is in fact the disarming of the blocking device. Typically, the blocking device is active when powered and automatically disengages when it is no longer powered.
Avantageusement, l’invention permet de remettre le véhicule en roue libre pour pouvoir déplacer le véhicule, tout en évitant que cette opération n’entraîne une décharge involontaire de la batterie. En cas de charge non suffisante, de l’énergie est puisée dans la batterie de traction pour permettre le désengagement du blocage de stationnement.Advantageously, the invention makes it possible to freewheel the vehicle again in order to move the vehicle, while preventing this operation from leading to involuntary discharge of the battery. If the charge is insufficient, energy is drawn from the traction battery to enable the parking lock to be disengaged.
Selon une variante, le contrôleur met en œuvre une alerte indiquant une recharge préalable de la batterie accessoire, lorsqu’il déclenche ledit transfert d’énergie.According to a variant, the controller implements an alert indicating a prior recharge of the accessory battery, when it triggers said energy transfer.
Cela permet d’informer l’utilisateur.This helps inform the user.
Selon une variante, le véhicule automobile comprend une interface ou un bouton de demande de déblocage, activant la mise en œuvre du contrôleur.According to one variant, the motor vehicle comprises an interface or an unlock request button, activating the implementation of the controller.
Cela permet de déclencher un contrôle de batterie accessoire et une mise en roue libre.This triggers an accessory battery check and freewheeling.
L’invention porte en outre sur un procédé de mise en roue libre pour un véhicule automobile selon l’invention, caractérisé en ce qu’il comprend les étapes suivantes :
- déterminer et comparer l’énergie disponible de la batterie accessoire sur la base de l’état de charge, et le besoin énergétique pour la mise en œuvre du moyen de déblocage,
- autoriser la mise en œuvre du moyen de déblocage si ladite énergie disponible est supérieure audit besoin énergétique ; ou déclencher un transfert d’énergie de la batterie de traction vers la batterie accessoire de sorte que ladite énergie disponible soit supérieure audit besoin énergétique, et ensuite autoriser la mise en œuvre du moyen de déblocage.The invention further relates to a freewheeling method for a motor vehicle according to the invention, characterized in that it comprises the following steps:
- determine and compare the available energy of the accessory battery on the basis of the state of charge, and the energy requirement for implementing the unlocking means,
- authorize the implementation of the unblocking means if said available energy is greater than said energy requirement; or trigger a transfer of energy from the traction battery to the accessory battery so that said available energy is greater than said energy requirement, and then authorize the implementation of the unlocking means.
Selon une variante, le procédé de mise en roue libre comprend en outre l’étape suivante : mettre en œuvre une alerte indiquant une recharge préalable de la batterie accessoire, lorsque l’étape de déclenchement est mise en œuvre.According to a variant, the freewheeling method further comprises the following step: implementing an alert indicating prior recharging of the accessory battery, when the triggering step is implemented.
Selon une variante, le procédé de mise en roue libre comprend en outre l’étape suivante : demander un déblocage, cette étape entraînant la mise en œuvre de l’étape de déterminer et comparer ladite énergie disponible et ledit besoin énergétique.According to a variant, the freewheeling method further comprises the following step: requesting an unblocking, this step leading to the implementation of the step of determining and comparing said available energy and said energy requirement.
Un autre objet de l’invention concerne un programme d’ordinateur comprenant des instructions de code de programme pour l’exécution des étapes du procédé de mise en roue libre selon l’invention, lorsque ledit programme fonctionne sur un ordinateur.Another object of the invention relates to a computer program comprising program code instructions for executing the steps of the freewheeling method according to the invention, when said program operates on a computer.
L'invention sera davantage détaillée par la description non limitative de variantes, et sur la base des figures annexées illustrant des variantes de l’inventions, dans lesquelles

L’invention propose une stratégie contrôlant et autorisant ou non la mise au neutre du véhicule en prenant en compte la possibilité ou pas de maintenir le dispositif de blocage en stationnement en position débloquée.The invention proposes a strategy controlling and authorizing or not the neutralization of the vehicle by taking into account the possibility or not of maintaining the parking locking device in the unlocked position.
Le dispositif de blocage en stationnement maintient le véhicule automobile arrêté. Il peut être implanté à la sortie de la boîte de vitesses. L’invention propose un moyen de déblocage pouvant être intégré au dispositif de blocage, pour mettre le véhicule automobile en roue libre.The parking lock device keeps the motor vehicle stopped. It can be installed at the output of the gearbox. The invention proposes an unlocking means that can be integrated into the blocking device, to freewheel the motor vehicle.
Le déblocage implique une action dépendant d’une alimentation électrique ce qui fait qu’il y a besoin d’un certain niveau de charge électrique pour que le déblocage puisse être effectué.Unblocking involves an action dependent on a power supply which means that a certain level of electrical charge is required for unblocking to be carried out.
La stratégie prend en compte la demande du conducteur, compare la consommation induite par la mise en roue libre du véhicule avec le seuil de remplissage de la batterie ; autorise ou pas le maintien en positon roue libre du véhicule et en prévient le conducteur du besoin de recharge si l’autorisation n’est pas donnée.The strategy takes into account the driver's request, compares the consumption induced by freewheeling the vehicle with the battery filling threshold; authorizes or not the vehicle to remain in the freewheel position and warns the driver of the need for recharging if authorization is not given.
Cette stratégie est applicable notamment lorsque le besoin de mise en roue libre est demandé par exemple pour une phase de lavage du véhicule dans une station qui tracte le véhicule durant un temps long (15mn).This strategy is applicable in particular when the need for freewheeling is requested, for example for a vehicle washing phase in a station which tows the vehicle for a long time (15 minutes).
Cette invention permet de garantir que lorsque la mise en roue libre du véhicule est autorisée par le superviseur du véhicule, ce mode sera opérationnel durant toute la durée indispensable à l’opération de lavage du véhicule.This invention ensures that when freewheeling of the vehicle is authorized by the vehicle supervisor, this mode will be operational for the entire duration essential for the vehicle washing operation.
Les véhicules de type hybride et ou électrique pur sont généralement équipés de système de blocage de la transmission lorsqu’ils sont arrêtés, et le moteur est coupé.Hybrid and or pure electric vehicles are generally equipped with a transmission locking system when they are stopped and the engine is turned off.
Ces systèmes sont activables par le levier de commande mis à disposition du conducteur, en position de stationnement (P) de ce levier ; ou via une interface homme machine, un bouton ou un autre dispositif.These systems can be activated by the control lever made available to the driver, in the park position (P) of this lever; or via a human machine interface, button or other device.
Cependant, ces systèmes de blocage s’activent également automatiquement lorsque le conducteur coupe son moteur, descend de son véhicule, lorsque la clef du véhicule n’est plus dans le véhicule ou s’éloigne à une certaine distance.However, these blocking systems are also activated automatically when the driver turns off the engine, gets out of the vehicle, when the vehicle key is no longer in the vehicle or moves away a certain distance.
Certaines situations de vie du véhicule peuvent cependant imposer une mise « en roue libre » du véhicule moteur coupé.However, certain vehicle life situations may require the vehicle to “freewheel” with the engine switched off.
Il peut s’agir de vouloir déplacer le véhicule de quelques dizaines de centimètres ou même d’utiliser une station de lavage qui tracte le véhicule.This may involve wanting to move the vehicle a few tens of centimeters or even using a car wash that tows the vehicle.
Il est donc connu de l’homme de l’art des procédures et ou des leviers spécifiques qui permettent au conducteur de choisir de placer son véhicule dans un mode dit de « roue libre » en désengageant le système de verrouillage automatique de la transmission.It is therefore known to those skilled in the art specific procedures and/or levers which allow the driver to choose to place their vehicle in a so-called “free wheel” mode by disengaging the automatic transmission locking system.
Si une procédure complexe permet de s’affranchir d’une mauvaise manipulation ou d’une action involontaire, la stratégie proposée permettra de vérifier si on peut maintenir la position « roue libre » durant une durée prédéterminée correspondant au cycle de lavage du véhicule dans ces stations spécifiques où le véhicule est tracté.If a complex procedure makes it possible to avoid mishandling or an involuntary action, the proposed strategy will make it possible to check whether the “free wheel” position can be maintained for a predetermined duration corresponding to the vehicle wash cycle in these specific stations where the vehicle is towed.
En effet, si le système n’est plus alimenté, alors le verrouillage est effectué automatiquement. Un verrouillage alors que le véhicule est tracté peut entraîner des dommages à la station de lavage et/ou au véhicule.Indeed, if the system is no longer powered, then the locking is carried out automatically. Locking while the vehicle is being towed may result in damage to the car wash and/or the vehicle.
