Description

PROCEDE DE COMMANDE D’UN EMBRAYAGE D’ACCOUPLEMENT D’UN MOTEUR THERMIQUE AVEC UNE BOITE DE VITESSES A DOUBLE EMBRAYAGEMETHOD FOR CONTROLLING A COUPLING CLUTCH OF A THERMAL ENGINE WITH A DOUBLE CLUTCH GEARBOX

Un aspect de l’invention se rapporte à un procédé de commande d’un embrayage d’accouplement d’un moteur thermique avec une boite de vitesses à double embrayage d’un véhicule. Le domaine technique de l’invention concerne tout particulièrement celui des boites de vitesses à double embrayage de véhicule, notamment automobile.One aspect of the invention relates to a method of controlling a coupling clutch of a heat engine with a dual-clutch gearbox of a vehicle. The technical field of the invention particularly concerns that of double clutch gearboxes for vehicles, particularly automobiles.

On connaît par exemple du document DE-A1-102007047589 un véhicule équipé notamment d’un moteur à combustion interne, d’une machine électrique tournante et d’un embrayage d’accouplement du moteur à combustion interne avec la machine électrique tournante.For example, we know from document DE-A1-102007047589 a vehicle equipped in particular with an internal combustion engine, a rotating electric machine and a clutch for coupling the internal combustion engine with the rotating electric machine.

Ce même document divulgue un procédé de désaccouplement du moteur thermique avec la machine électrique tournante. A cette fin, lorsque le conducteur retire son pied de la pédale d’accélérateur, le régime moteur du moteur à combustion interne est diminué jusqu’à atteindre un régime moteur réduit. Lorsque ce régime moteur réduit est atteint, la machine électrique tournante est désaccouplée du moteur à combustion interne en ouvrant l’embrayage d’accouplement du moteur à combustion interne avec la machine électrique tournante.This same document discloses a process for uncoupling the heat engine from the rotating electric machine. To this end, when the driver removes his foot from the accelerator pedal, the engine speed of the internal combustion engine is reduced until a reduced engine speed is reached. When this reduced engine speed is reached, the rotating electric machine is uncoupled from the internal combustion engine by opening the coupling clutch of the internal combustion engine with the rotating electric machine.

Ce procédé permet de désaccoupler la machine électrique tournante du moteur thermique suite à une demande du conducteur, par exemple lorsque celui-ci retire son pied de la pédale d’accélérateur.This process makes it possible to uncouple the rotating electric machine from the thermal engine following a request from the driver, for example when he removes his foot from the accelerator pedal.

En revanche, si son véhicule est à l’arrêt, qu’il est simplement sous contact et qu’il n’est pas encore démarré, l’accouplement peut être présent et maintenu inutilement. Dès lors, si un deuxième véhicule vient heurter le véhicule sous contact, l’embrayage d’accouplement peut être endommagé.On the other hand, if the vehicle is stationary, simply switched on and not yet started, the coupling may be present and maintained unnecessarily. Therefore, if a second vehicle hits the vehicle while the ignition is on, the coupling clutch may be damaged.

Le but de l’invention est de pallier les inconvénients de l’art antérieur en proposant un procédé de commande d’un embrayage d’accouplement d’un moteur thermique avec une boite de vitesses à double embrayage d’un véhicule permettant de protéger l’embrayage en cas de non sollicitation de celui-ci.The aim of the invention is to overcome the drawbacks of the prior art by proposing a method of controlling a coupling clutch of a heat engine with a double clutch gearbox of a vehicle making it possible to protect the clutch if it is not used.

Dans ce contexte, l’invention se rapporte ainsi, dans son acceptation la plus large, à un procédé de commande d’un embrayage d’accouplement d’un moteur thermique avec une boite de vitesses à double embrayage d’un véhicule, ledit procédé comportant les étapes, exécutées par des moyens de contrôle du véhicule, de :

  • détecter une action d’un conducteur qui présage d’une future commande de démarrage du moteur thermique, l’action du conducteur étant préalable à la commande de démarrage,
  • lorsque ladite action du conducteur est détectée, mettre en pression un système hydraulique de la boite de vitesses à double embrayage comportant un arbre de sortie et une machine électrique de traction agencée pour entraîner en rotation ledit arbre de sortie,
  • fermer l’embrayage,
  • détecter une mise sous contact du véhicule, le véhicule étant mis sous contact lorsqu’un utilisateur positionne une clé de démarrage du véhicule sur une position de mise sous contact ou lorsqu’un utilisateur appui seulement sur un bouton de démarrage,
  • déclencher un compteur de temps lorsque le véhicule est mis sous contact,
  • si aucune action de démarrer le véhicule n’a été détectée à l’expiration d’une période prédéterminée décomptée par le compteur de temps, ouvrir l’embrayage.
In this context, the invention thus relates, in its broadest acceptance, to a method of controlling a coupling clutch of a heat engine with a double-clutch gearbox of a vehicle, said method comprising the steps, executed by vehicle control means, of:
  • detect an action of a driver which presages a future start command of the thermal engine, the action of the driver being prior to the start command,
  • when said action of the driver is detected, pressurizing a hydraulic system of the double-clutch gearbox comprising an output shaft and an electric traction machine arranged to rotate said output shaft,
  • close the clutch,
  • detect an ignition of the vehicle, the vehicle being switched on when a user places a vehicle start key in an ignition position or when a user only presses a start button,
  • trigger a time counter when the vehicle is switched on,
  • if no action to start the vehicle has been detected at the expiration of a predetermined period counted down by the time counter, open the clutch.

Grâce à l’invention, l’embrayage d’accouplement du moteur thermique avec la boite de vitesses à double embrayage est ouvert dès lors que le véhicule est sous contact depuis un certain temps sans action du conducteur. Ainsi, si le conducteur tarde à démarrer son véhicule, en ouvrant l’embrayage, le moteur thermique et la boite de vitesses à double embrayage seront désaccouplés.Thanks to the invention, the coupling clutch of the thermal engine with the double-clutch gearbox is open as soon as the vehicle has been in contact for a certain time without action by the driver. Thus, if the driver delays starting his vehicle, by opening the clutch, the combustion engine and the dual-clutch gearbox will be uncoupled.

L’embrayage est donc protégé en cas de choc mais également le moteur thermique et la boite de vitesses à double embrayage.The clutch is therefore protected in the event of an impact, but also the combustion engine and the dual-clutch gearbox.

La montre les étapes d’un mode de mise en œuvre du procédé 100 de commande d’un embrayage d’accouplement d’un moteur thermique avec une boite de vitesses à double embrayage d’un véhicule selon l’invention.There shows the steps of a mode of implementation of the method 100 for controlling a coupling clutch of a heat engine with a double-clutch gearbox of a vehicle according to the invention.

Les étapes du procédé 100 sont exécutées par des moyens de contrôle tels que, par exemple, les moyens de contrôle 13 représentés à la .The steps of the method 100 are executed by control means such as, for example, the control means 13 represented in .

Le procédé 100 comporte une première étape de détecter 101 une action d’un conducteur qui présage d’une future commande de démarrage du moteur thermique 3 du véhicule 1. Dans un mode de réalisation, l’action du conducteur est une ouverture de porte conducteur du véhicule 1. L’action du conducteur est préalable à la commande de démarrage. Cette détection peut être réalisée au moyen d’un capteur d’ouverture de porte conducteur (non représenté) et transmise au calculateur multifonctions moteur 14.The method 100 comprises a first step of detecting 101 an action of a driver which presages a future start command of the thermal engine 3 of the vehicle 1. In one embodiment, the action of the driver is an opening of the driver's door of the vehicle 1. The driver's action is prior to the start command. This detection can be carried out by means of a driver's door opening sensor (not shown) and transmitted to the multifunction engine computer 14.

Lorsqu’une ouverture de porte est détectée, le procédé 100 comporte une étape de mettre en pression 102 le système hydraulique 11 de la boite de vitesses à double embrayage 7. Dans un mode de réalisation non limitatif, le calculateur multifonctions moteur 14 transmet une requête d’activation du système hydraulique 11 à l’unité de contrôle de transmission 15. Cette unité de contrôle de transmission 15 pilote ensuite la mise sous pression du système hydraulique 11, notamment via l’activation de la pompe à huile électrique 12. Il convient de noter que, dans ce mode de réalisation, l’étape de mettre en pression 102 le système hydraulique 11 de la boite de vitesses à double embrayage 7 est réalisée dès la détection de l’ouverture porte.When a door opening is detected, the method 100 includes a step of pressurizing 102 the hydraulic system 11 of the double-clutch gearbox 7. In a non-limiting embodiment, the multifunction engine computer 14 transmits a request activation of the hydraulic system 11 to the transmission control unit 15. This transmission control unit 15 then controls the pressurization of the hydraulic system 11, in particular via the activation of the electric oil pump 12. It is suitable note that, in this embodiment, the step of pressurizing 102 the hydraulic system 11 of the double-clutch gearbox 7 is carried out as soon as the door opening is detected.

Lorsque le système hydraulique 11 de la boite de vitesses à double embrayage 7 est mis sous pression, le procédé 100 comporte une étape de fermer 103 l’embrayage 10. Dans un mode de réalisation non limitatif, le calculateur multifonctions moteur 14 transmet une requête de fermeture de l’embrayage 10 à l’unité de contrôle de transmission 15. Cette unité de contrôle de transmission 15 pilote ensuite la fermeture de l’embrayage 10. Ainsi, dès lors que l’embrayage 10 est fermé, un couple peut être transmis entre le moteur thermique 3 et la boite de vitesses à double embrayage 7.When the hydraulic system 11 of the double clutch gearbox 7 is put under pressure, the method 100 includes a step of closing 103 the clutch 10. In a non-limiting embodiment, the multifunction engine computer 14 transmits a request for closing of the clutch 10 to the transmission control unit 15. This transmission control unit 15 then controls the closing of the clutch 10. Thus, as soon as the clutch 10 is closed, a torque can be transmitted between the thermal engine 3 and the double-clutch gearbox 7.

Le procédé 100 selon l’invention comporte en outre une étape de détecter 104 une mise sous contact du véhicule.The method 100 according to the invention further comprises a step of detecting 104 when the vehicle is switched on.

Dans une mise en œuvre non limitative, la mise sous contact du véhicule peut être détectée lorsque le conducteur positionne une clé de démarrage du véhicule sur une position de mise sous contact, dite « Ignition On » en anglais. Cette position de mise sous contact est habituellement située entre une position dite Off en anglais et une position dite contact en anglais.In a non-limiting implementation, the ignition of the vehicle can be detected when the driver positions a vehicle start key in an ignition position, called “Ignition On” in English. This ignition position is usually located between a position called Off in English and a position called contact in English.

Cette mise sous contact positionne sous tension plusieurs calculateurs et éléments électriques du véhicule 1 sans toutefois démarrer le moteur thermique 3 ni même la machine électrique de traction 9. Ainsi, le véhicule 1 n’est pas mis en mouvement.This switching on places several computers and electrical elements of vehicle 1 under voltage without, however, starting the thermal engine 3 or even the electric traction machine 9. Thus, the vehicle 1 is not set in motion.

Dans une mise en œuvre différente, la mise sous contact du véhicule peut être détectée lorsque l’utilisateur appui seulement sur un bouton de démarrage. Autrement dit, l’utilisateur n’appuie pas de façon simultanée sur le bouton de démarrage du véhicule et la pédale de frein. En effet, une telle action simultanée aurait pour action de démarrer le véhicule 1.In a different implementation, the ignition of the vehicle can be detected when the user only presses a start button. In other words, the user does not press the vehicle start button and the brake pedal simultaneously. In fact, such a simultaneous action would have the effect of starting vehicle 1.

Cette détection de mise sous contact peut être réalisée par exemple par le calculateur multifonctions moteur 14.This ignition detection can be carried out for example by the multifunction engine computer 14.

Lorsque le véhicule est mis sous contact, le procédé 100 comporte une étape de déclencher 105 un compteur de temps. Dans un mode de réalisation non limitatif, le calculateur multifonctions moteur 14 déclenche le compteur de temps.When the vehicle is switched on, the method 100 includes a step of triggering 105 a time counter. In a non-limiting embodiment, the multifunction engine computer 14 triggers the time counter.

Le compteur de temps décompte alors une période prédéterminée qui peut par exemple être comprise entre 30 secondes et 90 secondes, typiquement 60 secondes.The time counter then counts down a predetermined period which can for example be between 30 seconds and 90 seconds, typically 60 seconds.

Si aucune action de démarrer le véhicule n’a été détectée à l’expiration de la période prédéterminée décomptée par le compteur de temps, le procédé 100 comporte une étape d’ouvrir 106 l’embrayage 10.If no action to start the vehicle has been detected at the expiration of the predetermined period counted down by the time counter, the method 100 includes a step of opening 106 the clutch 10.

Dans un mode de réalisation non limitatif, le calculateur multifonctions moteur 14 transmet une requête d’ouverture de l’embrayage 10 à l’unité de contrôle de transmission 15. Cette unité de contrôle de transmission 15 pilote ensuite l’ouverture de l’embrayage 10.In a non-limiting embodiment, the multifunction engine computer 14 transmits a request to open the clutch 10 to the transmission control unit 15. This transmission control unit 15 then controls the opening of the clutch 10.

Dans un exemple de réalisation non limitatif, cette ouverture de l’embrayage 10 suit une consigne d’ouverture de l’embrayage 10 ayant la forme d’une rampe formée par un couple en fonction du temps.In a non-limiting embodiment, this opening of the clutch 10 follows an opening instruction of the clutch 10 having the shape of a ramp formed by a torque as a function of time.

Par exemple, lorsque l’embrayage 10 est fermé, il est en mesure de transmettre un couple compris entre 200 et 400nm, typiquement 300Nm.For example, when clutch 10 is closed, it is able to transmit a torque of between 200 and 400nm, typically 300Nm.

A l’inverse, lorsque l’embrayage 10 est ouvert, il n’est pas en mesure de transmettre un quelconque couple entre le moteur thermique 3 et la boite de vitesses à double embrayage 7.Conversely, when the clutch 10 is open, it is not able to transmit any torque between the thermal engine 3 and the double-clutch gearbox 7.

En suivant cette rampe, l’embrayage 10 peut passer d’un couple transmissible de 300Nm à 0Nm en quelque secondes, par exemple 2 secondes. Cette rampe permet de ne pas générer de ressenti pour le conducteur et être totalement transparent pour celui-ci.By following this ramp, the clutch 10 can go from a transmissible torque of 300Nm to 0Nm in a few seconds, for example 2 seconds. This ramp makes it possible not to generate any feeling for the driver and to be completely transparent for him.

Les différents aspects de l’invention susmentionnés présentent de nombreux avantages. Parmi ceux-ci, on peut citer, protéger en cas de choc :

  • l’embrayage 10,
  • la boite de vitesses à double embrayage 7, et
  • le moteur thermique 3.
The various aspects of the invention mentioned above have numerous advantages. Among these, we can cite, protecting in the event of shock:
  • the clutch 10,
  • the double clutch gearbox 7, and
  • the heat engine 3.

Il convient de noter que l’homme du métier est en mesure d’apporter différentes variantes aux aspects de l’invention précités, par exemple en modifiant la durée de la période prédéterminée permettant de déclencher l’ouverture de l’embrayage en cas d’inaction du conducteur.
It should be noted that those skilled in the art are able to make different variations to the aforementioned aspects of the invention, for example by modifying the duration of the predetermined period making it possible to trigger the opening of the clutch in the event of driver inaction.
