Description

L'invention concerne un procédé de limitation d'un effet de rebond d'un dispositif de verrouillage et de déverrouillage d'une serrure de porte d'un véhicule automobile comportant un système automatique d'accès et de démarrage.The invention relates to a method for limiting a rebound effect. a device for locking and unlocking a door lock of a motor vehicle comprising an automatic access and start-up.

On connaít des véhicules automobiles qui comportent un système d'accès et de démarrage sans intervention manuelle, appelé "accès et démarrage mains libres" (ADML), un tel système permettant de réaliser le déverrouillage des portières et/ou d'autres dispositifs de sécurité antivol du véhicule sans intervention manuelle de l'utilisateur. Pour cela, l'utilisateur est muni d'un moyen de reconnaissance ou identifiant qui permet à une unité de commande du déverrouillage du véhicule automobile de reconnaítre l'utilisateur autorisé, lorsque l'utilisateur est à proximité d'une porte du véhicule automobile et, généralement, lorsque l'utilisateur actionne une poignée d'ouverture ou plus généralement tout dispositif de commande d'ouverture extérieure de la porte.We know motor vehicles that have a system access and start without manual intervention, called "access and start hands free "(ADML), such a system for performing unlocking doors and / or other vehicle anti-theft security devices without manual user intervention. For this, the user is provided with a means of recognition or identifier which allows a unit to motor vehicle unlocking command to recognize the user authorized, when the user is near a door of the motor vehicle and generally when the user operates an opening handle or more generally any external opening control device Door.

La poignée d'ouverture de la porte peut comporter un capteur de commande automatique de verrouillage et un capteur de commande automatique de déverrouillage disposés par exemple sur la partie externe et sur la partie interne de la poignée, respectivement.The door opening handle may include a automatic locking control and an automatic control sensor release devices arranged for example on the external part and on the inner part of the handle, respectively.

Le ou les identifiants du système d'accès et de démarrage peuvent être constitués par exemple par une carte électronique ou un émetteur fournissant un code d'identification qui doit être reconnu par l'unité de commande de déverrouillage du véhicule automobile pour permettre la manoeuvre de déverrouillage.The identifier (s) of the access and start-up system may be constituted for example by an electronic card or a transmitter providing an identification code which must be recognized by the control unit unlocking the motor vehicle to allow maneuvering unlocking.

La configuration des poignées compatibles avec les systèmes d'accès et de démarrage de type ADML est telle qu'il se produit, de manière très fréquente, un rebond, c'est-à-dire un verrouillage et un déverrouillage successifs de la serrure de porte, lors de l'ouverture de la porte par un utilisateur.Configuration of handles compatible with access systems and ADML type startup is such that it occurs, very frequently, rebound, i.e. successive locking and unlocking door lock, when a user opens the door.

En effet, l'utilisateur muni d'un identifiant qui se trouve dans une zone de reconnaissance au voisinage de la porte du véhicule automobile touche la poignée de porte pour déverrouiller le véhicule automobile puis tire la poignée afin d'ouvrir la porte et, pour cela, saisit la poignée, si bien qu'il est amené le plus souvent à toucher le capteur de verrouillage qui se trouve à l'extérieur de la poignée de porte.Indeed, the user provided with an identifier which is in an area recognition near the door of the motor vehicle button the door handle to unlock the motor vehicle then pulls the handle in order to open the door and, for that, grab the handle, so that it is most often touched the locking sensor which is located the outside of the door handle.

Le système d'accès et de démarrage du véhicule recevant un ordre de verrouillage autorisé actionne le verrouillage de la serrure de porte et, du fait que la porte est ouverte, le système d'accès et de démarrage automatique détermine une anomalie du verrouillage de la porte à l'état ouvert et réalise immédiatement le déverrouillage de la porte. Le verrouillage et le déverrouillage successifs de la porte en position ouverte est ce qu'on appelle le "rebond".The access and start system of the vehicle receiving an order authorized locking system activates the locking of the door lock and, the door is open, the access and automatic start system determines an abnormality of the door lock in the open state and performs immediately unlocking the door. Locking and unlocking successive of the door in the open position is called the "rebound".

Le rebond présente des inconvénients du fait des bruits de la serrure de la porte du véhicule automobile, lors du déverrouillage initial, puis lors du verrouillage et du déverrouillage successifs constituant le rebond. En outre, si ces manoeuvres sont répétitives et se produisent par exemple à chaque ouverture de porte du véhicule automobile, il peut en résulter une usure excessive des parties mécaniques de la serrure de la porte du véhicule.Rebound has drawbacks due to noises from the lock of the door of the motor vehicle, upon initial unlocking, then upon successive locking and unlocking constituting the rebound. In addition, if these maneuvers are repetitive and occur for example at each motor vehicle door opening, excessive wear may result mechanical parts of the vehicle door lock.

Le but de l'invention est donc de proposer un procédé de limitation d'un effet de rebond d'un dispositif de verrouillage et de déverrouillage d'une serrure de porte d'un véhicule automobile comportant, dans une poignée de la porte, un capteur de commande automatique de verrouillage et un capteur de commande automatique de déverrouillage, en présence d'un utilisateur, le rebond pouvant intervenir par déclenchement successif d'un verrouillage et d'un déverrouillage, lorsque l'utilisateur sollicite de manière non voulue le capteur de verrouillage après déverrouillage de la porte, de telle sorte que l'effet de rebond ne se produise pas dans la plupart des cas de manoeuvre d'ouverture d'une porte du véhicule automobile par un utilisateur.The object of the invention is therefore to propose a method of limitation a rebound effect of a device for locking and unlocking a door lock of a motor vehicle comprising, in a handle of the door, an automatic locking control sensor and a sensor automatic unlocking control, in the presence of a user, rebound can occur by successive triggering of a lock and an unlocking, when the user unintentionally requests the locking sensor after unlocking the door, so that rebound effect does not occur in most maneuvers opening of a door of the motor vehicle by a user.

Dans ce but, lorsque le capteur de verrouillage est sollicité après déverrouillage de la porte du véhicule, on diffère la réalisation du verrouillage pendant une phase d'attente de durée prédéterminée, à l'issue de la phase d'attente, on réalise une détection de l'état de sollicitation du capteur de déverrouillage et, dans le cas où le capteur de déverrouillage est sollicité, on n'effectue aucune action de verrouillage et de déverrouillage successifs.For this purpose, when the locking sensor is pressed after unlocking of the vehicle door, we differ the realization of the locking during a waiting phase of predetermined duration, at the end of the phase waiting, a detection of the stressing state of the unlocking sensor is carried out and, in the case where the unlocking sensor is requested, we does not perform any successive locking and unlocking actions.

De préférence :

  • lorsque le capteur de déverrouillage n'est pas sollicité, à l'issue de la phase d'attente, on réalise une détection de l'état d'ouverture ou de fermeture de la porte du véhicule automobile et, dans le cas où l'on détermine un état de fermeture de la porte, on réalise un verrouillage de la serrure de porte et, dans le cas où l'on détermine un état d'ouverture de la porte, on réalise successivement un verrouillage puis un déverrouillage de la serrure de porte ;
  • le capteur de verrouillage est disposé sur une face externe de la poignée de la porte du véhicule et le capteur de déverrouillage est disposé sur une face interne de la poignée de la porte, si bien que le capteur de verrouillage et le capteur de déverrouillage sont susceptibles d'être sollicités par une main de l'utilisateur venant en contact avec l'une au moins de la face interne et de la face externe de la poignée ou avec la face interne et la face externe de la poignée, lorsque l'utilisateur saisit la poignée.
Preferably:
  • when the unlocking sensor is not requested, at the end of the waiting phase, a detection is made of the state of opening or closing of the door of the motor vehicle and, in the case where the a state of closing of the door is determined, a locking of the door lock is carried out and, in the case where a state of opening of the door is determined, a locking and then unlocking of the lock is successively carried out door ;
  • the locking sensor is arranged on an external face of the handle of the vehicle door and the unlocking sensor is arranged on an internal face of the door handle, so that the locking sensor and the unlocking sensor are susceptible to be acted on by a hand of the user coming into contact with at least one of the internal face and the external face of the handle or with the internal face and the external face of the handle, when the user grasps the handle.

Afin de bien faire comprendre l'invention, on va décrire à titre d'exemple, en se référant aux figures jointes en annexe, un système d'accès et de démarrage automatique d'un véhicule automobile et la mise en oeuvre du procédé selon l'invention pour limiter des effets de rebond à l'ouverture d'une porte du véhicule automobile.In order to clearly understand the invention, we will describe by way of example, with reference to the attached figures, an access and automatic starting of a motor vehicle and the implementation of method according to the invention for limiting rebound effects on opening of a door of the motor vehicle.

La figure 1 est une vue schématique en plan d'un véhicule automobile et de zones de reconnaissance d'identifiants à l'intérieur et à l'extérieur du véhicule.Figure 1 is a schematic plan view of a motor vehicle and identifier recognition zones inside and outside the vehicle.

La figure 2 est une vue en perspective d'une poignée de porte du véhicule automobile équipée de capteurs de verrouillage et de déverrouillage.Figure 2 is a perspective view of a vehicle door handle automobile fitted with locking and unlocking sensors.

La figure 3 est un organigramme montrant la mise en oeuvre du procédé suivant l'invention.Figure 3 is a flowchart showing the implementation of the method according to the invention.

Sur la figure 1, on a représenté de manière très schématique, dans une vue en plan, un véhicule automobile désigné de manière générale par le repère 1. Le véhicule automobile comporte une partie interne 2 comportant elle-même l'habitacle proprement dit 2a et une partie arrière 2b ainsi qu'un compartiment moteur 3. In Figure 1, there is shown very schematically, in a plan view, a motor vehicle generally designated by the mark 1. The motor vehicle has an internal part 2 comprising itself the passenger compartment 2a and a rear part 2b as well as a engine compartment 3.

Le véhicule automobile 1 est équipé d'un système d'accès et de démarrage de type ADML utilisant des moyens de détection d'identifiants à l'intérieur et à l'extérieur du véhicule automobile.Motor vehicle 1 is equipped with an access and starting system of ADML type using means of detection of identifiers to inside and outside of the motor vehicle.

Un premier moyen de détection permet de détecter la présence d'identifiants dans la partie interne 2 du véhicule automobile. Le système d'accès et de démarrage contrôlé du véhicule automobile comporte également des moyens de détection extérieurs constitués par trois antennes dont les zones de détection 4a, 4b et 4c ont été représentées sur la figure 1. Les zones de détection 4a et 4b permettent de détecter la présence d'un identifiant au voisinage d'une porte du véhicule automobile.A first detection means makes it possible to detect the presence identifiers in the internal part 2 of the motor vehicle. The system access and controlled starting of the motor vehicle also includes external detection means consisting of three antennas including the detection zones 4a, 4b and 4c have been shown in FIG. 1. The detection zones 4a and 4b make it possible to detect the presence of an identifier in the vicinity of a door of the motor vehicle.

Sur la figure 2, on a représenté une partie d'une porte 5 du véhicule automobile qui peut être par exemple la porte avant donnant accès à la place du conducteur.In FIG. 2, part of a door 5 of the vehicle is shown. automobile which can be for example the front door giving access to the driver's seat.

Suivant un bord 9 de la porte 5 est fixée une serrure 8 de verrouillage de la porte 5 du véhicule automobile en position fermée qui est commandée par le système d'accès et de démarrage automatique par l'intermédiaire d'une poignée 6 d'ouverture de porte solidaire de la structure de la porte 5. Sur la poignée 6 sont montés, sur une face avant de la poignée, un capteur de verrouillage 7a et, sur la face arrière de la poignée (non visible sur la figure 2), un capteur 7b de déverrouillage du véhicule automobile.Next to an edge 9 of the door 5 is fixed a lock 8 for locking of the door 5 of the motor vehicle in the closed position which is controlled through the access system and automatic start through a door opening handle 6 secured to the structure of the door 5. On the handle 6 are mounted, on a front face of the handle, a sensor lock 7a and, on the rear face of the handle (not visible in the figure 2), a motor vehicle unlocking sensor 7b.

Lorsqu'un utilisateur autorisé, c'est-à-dire un utilisateur muni d'un identifiant se présente dans une zone telle que la zone 4a représentée sur la figure 1, au voisinage de la porte 5, il est reconnu par le système automatique d'accès et de démarrage du véhicule automobile et peut actionner le capteur de déverrouillage 7b sur la face interne de la poignée pour déverrouiller la serrure de la porte 5 assurant sa condamnation en position de fermeture. Pour cela, il suffit généralement que l'utilisateur touche la face accessible du capteur 7b sur la face interne de la poignée. L'utilisateur saisit alors la poignée pour ouvrir la porte 5 du véhicule automobile. Lorsqu'il saisit la poignée, l'utilisateur touche généralement le capteur de verrouillage 7a situé sur la face extérieure de la poignée 6, de telle sorte que le système d'accès et de démarrage automatique du véhicule automobile perçoit un ordre de verrouillage autorisé. When an authorized user, i.e. a user with a identifier occurs in an area such as area 4a shown on the figure 1, near door 5, it is recognized by the automatic system access and starting of the motor vehicle and can activate the unlocking sensor 7b on the inside of the handle to unlock the door lock 5 ensuring its locking in the position of closing. For this, it is usually enough for the user to touch the face accessible from sensor 7b on the internal face of the handle. User enters then the handle to open the door 5 of the motor vehicle. When he grabs the handle, the user generally touches the locking sensor 7a located on the outside of handle 6 so that the system motor vehicle access and automatic start system receives an order locking allowed.

Dans le cas d'un système d'accès et de démarrage selon l'art antérieur, l'ordre de verrouillage entraíne effectivement un verrouillage de la serrure de la porte 5 en position d'ouverture. Le système d'accès et de démarrage automatique du véhicule détecte alors un verrouillage d'une portière en position ouverte et commande un déverrouillage immédiat de la serrure de la porte 5. Il en résulte des bruits de serrure et des manoeuvres intempestives de la serrure de la porte 5.In the case of an access and starting system according to the prior art, the locking order effectively leads to a locking of the lock of door 5 in the open position. The access and starting system vehicle automatically detects a door lock by open position and commands immediate unlocking of the lock door 5. This results in lock noises and untimely maneuvers the door lock 5.

Sur la figure 3, on a représenté un organigramme concernant la mise en oeuvre du procédé, c'est-à-dire l'utilisation d'un système d'accès et de démarrage automatique programmé pour la mise en oeuvre de l'invention.In Figure 3, there is shown a flowchart concerning the setting implementation of the method, that is to say the use of an access and automatic start programmed for the implementation of the invention.

Sur la figure 3 on a représenté une première étape 10 qui correspond au déverrouillage de la serrure 8 de la porte 5 par un utilisateur autorisé dont la main vient en contact avec le capteur de déverrouillage 7b de la poignée 6.In Figure 3 there is shown a first step 10 which corresponds when the lock 8 of door 5 is unlocked by an authorized user, the hand comes into contact with the unlocking sensor 7b of the handle 6.

L'étape suivante 11 est mise en oeuvre lorsque l'utilisateur autorisé saisit la poignée pour ouvrir la porte et sollicite, de manière non voulue, le capteur de verrouillage.The next step 11 is implemented when the authorized user takes hold of the handle to open the door and unintentionally pushes the locking sensor.

L'étape 12 est une phase d'attente dont la durée peut être de quelques millisecondes à quelques secondes et, par exemple de l'ordre de une seconde, pendant laquelle le système d'accès et de démarrage automatique ne transmet aucun ordre à la suite de la sollicitation du capteur de verrouillage.Step 12 is a waiting phase, the duration of which can be a few milliseconds to a few seconds and, for example of the order of one second, during which the access and automatic start system does not transmit any order following the request of the locking sensor.

L'étape 13 est une étape logique pendant laquelle, à l'issue de la phase d'attente de l'étape 12, le système d'accès et de déverrouillage du véhicule automobile détermine si le capteur de déverrouillage 7b est actionné par la main de l'utilisateur, c'est-à-dire si la main de l'utilisateur est en contact avec le capteur de déverrouillage 7b.Step 13 is a logical step during which, at the end of the waiting phase of step 12, the access and unlocking system of the motor vehicle determines whether the unlocking sensor 7b is actuated by the user's hand, i.e. if the user's hand is in contact with the unlocking sensor 7b.

Suivant la réponse donnée par la logique du système d'accès et de déverrouillage, c'est-à-dire suivant que le capteur de déverrouillage est sollicité ou non, on passe à une étape respective 14 ou 15 dans laquelle on détermine, grâce à un capteur, si la porte 5 du véhicule automobile est en position ouverte ou non. According to the answer given by the logic of the access and unlocking, i.e. depending on whether the unlocking sensor is activated or not, we go to a respective step 14 or 15 in which we determine, thanks to a sensor, if the door 5 of the motor vehicle is in position open or not.

Dans le cas où le capteur de déverrouillage est sollicité, c'est-à-dire dans le cas où l'utilisateur a gardé la main sur la poignée du véhicule automobile après avoir actionné le capteur de verrouillage, qu'on détermine une position ouverte ou fermée de la porte à l'étape 14, on n'effectue aucune action sur le système de verrouillage et de déverrouillage de la serrure de la porte 5, comme il apparaít aux étapes 16 et 17.In the event that the unlocking sensor is requested, i.e. in the case where the user has kept his hand on the handle of the motor vehicle after activating the locking sensor, that a open or closed position of the door in step 14, no action on the locking and unlocking system of the lock of the door 5, as it appears in steps 16 and 17.

L'utilisateur peut avoir maintenu sa main sur la poignée de la porte 5 du véhicule après avoir ouvert la porte ou peut avoir refermé la porte ou maintenu la porte fermée, sa main étant restée sur la poignée, dans l'attente d'une action effective ultérieure, par exemple l'ouverture ou la réouverture de la porte.The user may have held his hand on the door handle 5 after opening the door or may have closed the door or kept the door closed, his hand remaining on the handle, waiting subsequent effective action, for example the opening or reopening of the door.

Dans ce cas, le système selon l'invention évite tout verrouillage intempestif interdisant une ouverture ou une réouverture de la porte et tout effet de rebond sur la serrure de la porte en position ouverte.In this case, the system according to the invention avoids any untimely locking prohibiting opening or reopening of the door and all rebound effect on the door lock in the open position.

Si, à l'étape 13, on détermine que le capteur de déverrouillage n'est pas sollicité, c'est-à-dire que la main de l'utilisateur n'est pas restée sur la poignée 6 de la porte 5, à l'étape 15, on détermine si la porte est en position ouverte ou non.If, in step 13, it is determined that the unlocking sensor is not not used, i.e. the user's hand did not remain on the handle 6 of door 5, in step 15, it is determined whether the door is in position open or not.

Si la porte est en position fermée, à l'étape 19, on réalise le verrouillage de la serrure de porte, l'utilisateur qui a laissé la porte fermée ou a refermé la porte désirant verrouiller à nouveau le véhicule avant de s'éloigner. On réalise donc effectivement le verrouillage de la serrure de porte à l'étape 19.If the door is in the closed position, in step 19, the locking is carried out of the door lock, the user who left the door closed or closed the door wishing to lock the vehicle again before moving away. We therefore effectively carry out the locking of the door lock in step 19.

Dans le cas où, à l'étape 15, on détermine que la porte est en position ouverte, à l'étape 18, on réalise successivement un verrouillage puis un déverrouillage de la porte en position ouverte, c'est-à-dire qu'il se produit un rebond. Dans ce cas, l'utilisateur ayant lâché la poignée peut, soit refermer la porte, soit pénétrer dans le véhicule automobile. Dans ce seul cas, c'est-à-dire dans le cas où l'utilisateur a relâché la poignée après avoir ouvert la porte, à l'issue de la phase d'attente, il se produit un rebond, ce qui limite de manière très importante les possibilités de réalisation du rebond.In the case where, in step 15, it is determined that the door is in position open, in step 18, locking and unlocking are carried out successively of the door in the open position, i.e. there is a rebound. In this case, the user who released the handle can either close the door, or enter the motor vehicle. In this only case, that is to say in case the user has released the handle after opening the door, at the end of the waiting phase, there is a rebound, which limits very importantly the possibilities of achieving the rebound.

De préférence, la durée de la phase d'attente 12 sera déterminée de manière que l'utilisateur désirant entrer dans le véhicule automobile a toujours la poignée de la porte en main à l'issue de la phase d'attente, ce qui supprime toute possibilité de rebond pour une utilisation habituelle du système de déverrouillage et d'ouverture de porte.Preferably, the duration of the waiting phase 12 will be determined by way that the user wishing to enter the motor vehicle has always the door handle in hand at the end of the waiting phase, which eliminates any possibility of kickback for normal use of the system for unlocking and opening the door.

La probabilité pour que l'utilisateur ait ouvert la porte et lâché la poignée à l'issue de la phase d'attente est donc faible, si bien que l'apparition du rebond est peu probable.The probability that the user opened the door and let go of the handle at the end of the waiting phase is therefore low, so that the appearance rebound is unlikely.

Il est à remarquer que le procédé suivant l'invention ne demande aucune modification de la serrure de la porte, seule la programmation du système d'accès et de démarrage automatique du véhicule automobile étant modifiée à partir de l'étape 12 de l'organigramme représenté sur la figure 3.It should be noted that the method according to the invention does not require any modification of the door lock, only system programming access and automatic starting of the motor vehicle being modified from step 12 of the flowchart shown in Figure 3.

L'adaptation d'un système d'accès et de démarrage d'un véhicule automobile pour limiter l'apparition de rebond, selon le procédé de l'invention, est donc pratiquement gratuite.Adaptation of a motor vehicle access and starting system to limit the appearance of rebound, according to the method of the invention, is therefore practically free.

L'invention s'applique à de nombreux véhicules automobiles comportant des systèmes d'accès et de démarrage automatiques, par exemple de type ADML.The invention applies to many motor vehicles comprising automatic start and access systems, for example ADML type.
