Description

L'invention concerne les véhicules, en particulier les véhicules automobiles, qui sont équipés de systèmes permettant d'agir à distance au niveau d'au moins un de leurs ouvrants, par exemple au niveau d'un ouvrant de coffre, pour en déclencher l'ouverture ou la fermeture. Elle concerne aussi les systèmes permettant la réalisation d'une telle commande.The invention relates to vehicles, in particular motor vehicles, which are equipped with systems for remote action at least one of their opening, for example at the level of a boot opening, to trigger the opening or closing. It also concerns systems allowing the realization of such an order.

Il existe, à ce jour, un certain nombre de véhicules automobiles équipés de systèmes d'accès "mains libres" permettant à un utilisateur d'agir sur un véhicule, depuis l'extérieur de ce véhicule, si cet utilisateur porte un identifiant approprié, de type transpondeur, qui est reconnu par un dispositif de reconnaissance émetteur/récepteur, équipant le véhicule, lorsqu'il se trouve dans une zone géographique déterminée au voisinage du véhicule. Un tel système d'accès agit, par exemple, sur le mécanisme de verrouillage/déverrouillage des serrures des ouvrants d'un véhicule automobile, de manière à permettre l'ouverture de ces ouvrants par un ou des utilisateurs, à partir du moment où le dispositif de reconnaissance, que comporte le véhicule, a détecté la présence à distance convenable d'un identifiant déterminé.There are, to date, a number of motor vehicles equipped with "hands free" access systems allowing a user to act on a vehicle, from outside the vehicle, if that user has an identifier transponder type, which is recognized by a transceiver recognition, fitted to the vehicle when it is in a defined geographical area in the vicinity of the vehicle. Such access system acts, for example, on the mechanism of locking / unlocking the locks of the openings of a motor vehicle, in order to allow the opening of these doors by one or more users, to from the moment when the recognition device, which includes the vehicle, detected the presence at a suitable distance of a given identifier.

Il n'est généralement pas prévu une ouverture automatique de tous les ouvrants d'un véhicule et en particulier d'un véhicule automobile, par le système d'accès, en plus du déverrouillage des serrures, dans la mesure où, une telle ouverture complète en simultané de tous les ouvrants n'a pas nécessairement un intérêt dans le cas de véhicules automobiles. Une telle ouverture pourrait d'ailleurs être une source de risques pour un véhicule à ouvrants, de type battant, et pour ce qui se trouverait alors dans son environnement. Par contre, il peut être commode pour un utilisateur de pouvoir commander l'ouverture et/ou la fermeture d'un des ouvrants, par exemple une portière à ouverture latérale ou un ouvrant de coffre, sans avoir à manipuler un organe de commande. Ceci a de l'intérêt, par exemple, pour un utilisateur qui veut faire entrer dans un véhicule une charge qu'il porte entre ses mains, sans avoir à poser cette charge pour réaliser manuellement l'ouverture de l'ouvrant, ou alternativement pour fermer un ouvrant, lorsqu'il a les mains pleines.There is usually no automatic opening of all openings of a vehicle and in particular of a motor vehicle, by the access system, in addition to unlocking the locks, insofar as such an opening complete simultaneous of all the openings does not necessarily have an interest in the case of motor vehicles. Such an opening could be a source of risks for a swing-open vehicle, and for this who would then be in his environment. However, it can be convenient for a user to be able to control the opening and / or the closing one of the openings, for example a door with lateral opening or a boot lid, without having to manipulate a control member. This has of interest, for example, for a user who wants to get into a vehicle a load he carries in his hands, without having to put this load to manually make the opening of the opening, or alternatively to close an opening when he has his hands full.

Il faut alors que soit prévu un moyen permettant à l'utilisateur de déclencher l'ouverture et/ou la fermeture d'un ouvrant, selon sa volonté, à partir du moment où il remplit les conditions exigées pour obtenir une telle ouverture. A means must then be provided for the user to trigger the opening and / or closing of an opening, according to his will, from the moment where he fulfills the conditions required to obtain such an opening.

Un système de commande à distance connu permet de commander une ouverture automatique d'un ouvrant de coffre, il comporte des capteurs qui sont disposés au voisinage du coffre, par exemple de part et d'autre de la plaque d'immatriculation jouxtant ce coffre, et qui sont aptes à détecter la présence d'une main à proximité. La commande d'ouverture du coffre est déclenchée par la détection successive de la main d'un utilisateur devant chacun des capteurs. Cette détection de présences successives d'une main devant chacun des détecteurs au cours du mouvement de commande par va-et-vient est prévue pour limiter les risques de déclenchement par un utilisateur, voire par un tiers, faisant des gestes au niveau des capteurs, sans intention de commander l'ouverture. Par contre, le déclenchement d'une commande par un mouvement de ce genre n'est pas nécessairement pratique, en particulier lorsque l'utilisateur porte une charge peu facile à manier, par exemple en raison de son encombrement ou de son poids.A known remote control system makes it possible to control a automatic opening of a boot lid, it includes sensors that are arranged in the vicinity of the trunk, for example on either side of the license plate adjoining this trunk, and which are able to detect the presence of a hand nearby. The safe opening command is triggered by the successive detection of a user's hand in front of each of the sensors. This detection of successive presences of a hand in front of each of the detectors during the command movement by back and forth is planned to limit the risks of triggering by a user, or even by a third party, making gestures at the sensor level, without intention to order the opening. On the other hand, the triggering of a command by a movement of this kind is not necessarily practical, especially when the user is carrying a load that is not easy to handle, for example because of its size or weight.

On connaít également le document FR 2733783 qui divulgue un dispositif conforme au préambule de la revendication 1. L'invention propose un système de commande pour ouvrant de véhicule et en particulier pour ouvrant de coffre d'un véhicule, tel qu'un véhicule automobile, ce système étant agencé pour permettre à un utilisateur d'agir à distance sur un mécanisme actionneur lié à l'ouvrant et logé dans le véhicule.Also known is document FR 2733783 which discloses a device in accordance with the preamble of claim 1. The invention proposes a control system for opening a vehicle and in particular for opening trunk of a vehicle, such as a vehicle automobile, this system being arranged to allow a user to act in distance on an actuator mechanism linked to the opening and housed in the vehicle.

Selon une caractéristique de l'invention, le système de commande comporte des moyens, au niveau du véhicule, pour commander au moins une action du mécanisme actionneur, à partir des signaux produits par des capteurs de mouvement, lorsqu'un même mouvement détecté par l'intermédiaire de ces capteurs selon leurs axes privilégiés respectifs est traduit par un mouvement déterminé selon un axe résultant dont l'orientation est fonction de la combinaison de capteurs réalisée.According to one feature of the invention, the control system comprises means, at the vehicle level, to control at least one action of the actuator mechanism, from the signals produced by sensors of movement, when the same movement detected through these sensors according to their respective preferred axes is reflected by a movement determined according to a resulting axis whose orientation is a function of the combination of sensors realized.

Selon une variante de l'invention, le système de commande comporte des moyens par l'intermédiaire desquels la vitesse de mouvement, selon l'axe privilégié du capteur ou selon l'axe résultant des capteurs du système de commande, qui est déterminée à partir des signaux fournis par chaque capteur, est exploitée pour la commande du mécanisme actionneur, en cas de détection d'un mouvement. According to a variant of the invention, the control system comprises means through which the speed of movement, along the axis preferred sensor or along the axis resulting from the sensors of the system of command, which is determined from the signals provided by each sensor, is used for the control of the actuator mechanism, in case detection of a movement.

Selon l'invention, l'orientation du ou des capteurs sur le véhicule est fixée de manière que l'axe privilégié de chaque capteur du système de commande qui est associé au mécanisme actionneur d'un ouvrant soit orienté pour détecter des mouvements s'effectuant dans au moins un des sens correspondant respectivement au sens d'ouverture ou de fermeture de l'ouvrant.According to the invention, the orientation of the sensor (s) on the vehicle is fixed by way that the privileged axis of each sensor of the control system which is associated with the actuator mechanism of an opening is oriented to detect movements taking place in at least one of the corresponding directions respectively in the sense of opening or closing of the opening.

  • Un schéma de principe présentant les éléments constitutifs essentiels d'un système de commande permettant à un utilisateur d'agir à distance sur un mécanisme actionneur, lié à un ouvrant d'un véhicule, est présenté, à titre d'exemple, sur la figure 1. Il y est associé à un système d'accès "mains libres", tel qu'évoqué plus haut, étant entendu que cette association préférablement envisagée, n'est cependant pas indispensable. A schematic diagram presenting the essential elements of a control system enabling a user to act remotely on a actuator mechanism, linked to an opening of a vehicle, is presented, as a for example, in Figure 1. It is associated with a system of access "hands free", as mentioned above, it being understood that this association preferably envisaged, however, is not essential.

    Le système de commande, selon l'invention, est prévu pour permettre à un utilisateur d'agir sur un mécanisme actionneur 1 d'un ouvrant d'un véhicule, non représenté sur cette figure.The control system according to the invention is intended to enable a user to act on an actuator mechanism 1 of an opening of a vehicle, no represented in this figure.

    L'invention est destinée, en particulier, à être mise en oeuvre sur un véhicule automobile et au niveau d'un ouvrant, par exemple un ouvrant de coffre. Elle est, bien entendu, applicable aux autres ouvrants que le véhicule est susceptible de comporter.The invention is intended, in particular, to be implemented on a vehicle automobile and at the level of an opening, for example a boot lid. She is, of course, applicable to other openings that the vehicle is likely to involve.

    Le mécanisme actionneur 1, lié à l'ouvrant qui est ici considéré, est par exemple un mécanisme permettant d'assurer l'ouverture et/ou la fermeture de l'ouvrant. Il est ici supposé apte à agir en réponse à au moins une action de commande exécutée par un utilisateur qui lui est envoyée au travers d'une logique de commande 3. Comme connu, la réponse du mécanisme actionneur à une commande peut être obtenue par voie mécanique, par exemple en faisant intervenir un ou des ressorts, ou par voie électromécanique, par exemple en faisant intervenir un moteur électrique.The actuator mechanism 1, related to the opening which is considered here, is for example a mechanism to ensure the opening and / or closing of the opening. he is here assumed to be able to act in response to at least one control action executed by a user sent to him through a logic of 3. As known, the response of the actuator mechanism to a control can be obtained mechanically, for example by making intervene one or springs, or electromechanically, for example in involving an electric motor.

    Dans une variante de réalisation, le mécanisme actionneur 1 est associé à un mécanisme de verrouillage/déverrouillage 2 d'une serrure de l'ouvrant auquel il est affecté, de manière à permettre l'ouverture de l'ouvrant, lorsque la serrure est déverrouillée et, éventuellement, pour permettre sa fermeture, avant qu'un verrouillage de l'ouvrant en position fermée ne soit réalisé. Comme il est connu, les opérations de verrouillage et de déverrouillage d'au moins un ouvrant d'un véhicule sont susceptibles d'être commandées par l'intermédiaire d'une unité logique de contrôle d'accès équipant le véhicule. Cette unité réagit par exemple à une action réalisée par l'utilisateur au moyen d'un organe de commande ou de télécommande. Elle peut éventuellement impliquer la présence d'un identifiant déterminé d'utilisateur au niveau du véhicule, en particulier, si celui-ci est équipé d'un système d'accès "mains libres" tel qu'évoqué ci-dessus et tel qu'envisagé sur la figure 1. Dans l'exemple présenté et selon une forme connue de réalisation, l'identifiant attribué à un utilisateur est de type transpondeur, et il est apte à transmettre un signal d'identification en réponse à un signal d'interrogation déterminé. Ce signal d'interrogation est émis sous la supervision d'une logique de contrôle 4, dotée de moyens de reconnaissance d'identifiant, dont le véhicule est équipé. Le dispositif d'émission/réception est ici symbolisé par l'antenne 5 qui est supposée reliée à la logique 4 par un émetteur-récepteur, non représenté.In an alternative embodiment, the actuator mechanism 1 is associated with a locking / unlocking mechanism 2 of a lock of the sash to which it is affected, so as to allow the opening of the opening, when the lock is unlocked and, possibly, to allow its closure, before a locking of the opening in the closed position is achieved. As he is known, locking and unlocking operations of at least one opening of a vehicle are likely to be controlled through a unit access control logic equipping the vehicle. This unit reacts for example an action performed by the user by means of a control device or remote control. It can possibly involve the presence of an identifier vehicle-specific user, in particular, if it is equipped with a system of access "hands free" as evoked above and such Figure 1. In the example presented and in a known form realization, the identifier assigned to a user is transponder type, and it is able to transmit an identification signal in response to a signal determined question. This interrogation signal is issued under the supervision a control logic 4, provided with identifier recognition means, whose vehicle is equipped. The transmission / reception device is here symbolized by the antenna 5 which is supposed to be connected to logic 4 by a transceiver, not shown.

    A titre d'exemple et comme envisagé plus haut, il est ici supposé que la logique de contrôle d'accès 4 permette d'agir sur le mécanisme de verrouillage/déverrouillage 2 et qu'elle coopère avec la logique de commande 3 agissant sur le mécanisme actionneur 1. Ces deux logiques sont éventuellement combinées dans un ensemble logique 6, comme connu de l'homme de métier, leur coopération est effective, lors des opérations où les mécanismes 1 et 2 sont impliqués.As an example and as envisaged above, it is here assumed that the logic access control 4 allows to act on the mechanism of locking / unlocking 2 and cooperating with the control logic 3 acting on the actuator mechanism 1. These two logics are possibly combined in a logical set 6, as known from the person skilled in the art, their cooperation is effective in operations where the mechanisms 1 and 2 are involved.

    Selon l'invention, il est prévu que la logique de commande 3, qui permet d'agir sur le mécanisme actionneur 1 lié à un ouvrant, est dotée de moyens lui permettant de réagir en fonction du mouvement d'un objet, et en particulier d'une main, dans une zone délimitée de commande jouxtant l'ouvrant.According to the invention, it is provided that the control logic 3, which makes it possible to act on the actuator mechanism 1 linked to an opening, is provided with means to react according to the movement of an object, and in particular with one hand, in a delimited zone of command adjoining the opening.

    Le mouvement est déterminé à partir de signaux qui sont obtenus d'au moins un capteur de mouvement 7 qui est, par exemple, placé sur le véhicule à proximité de l'ouvrant, comme illustré sur les figures 2 et 6, ou encore sur l'ouvrant lui-même, comme présenté sur la figure 4. Le ou les capteurs peuvent ainsi être placé(s) au-dessus ou au-dessous du niveau de l'ouvrant sur le véhicule et par exemple sur un pare-chocs voisin de cet ouvrant, lorsque celui-ci est un ouvrant de coffre. Un positionnement sur un côté du véhicule, à proximité d'un ouvrant de coffre, peut aussi être envisagé pour permettre une commande de cet ouvrant, lorsque seul un accès latéral est possible, en raison des conditions de stationnement du véhicule.Movement is determined from signals that are obtained from at least one motion sensor 7 which is, for example, placed on the vehicle nearby opening, as illustrated in Figures 2 and 6, or on the opening itself, as shown in FIG. 4. The sensor (s) can thus be placed above or below the level of the opening on the vehicle and example on a bumper next to this opening, when it is an opening of chest. A positioning on one side of the vehicle, close to an opening can also be considered to allow an order of this opening, when only lateral access is possible, because of the conditions of vehicle parking.

    Le capteur 7, envisagé ci-dessus, comporte, par exemple, des moyens lui permettant d'émettre des signaux, à des fins d'évaluation, et de les récupérer, lorsqu'ils sont réfléchis par un élément constituant un réflecteur qui est alors situé dans le champ du capteur. Cet élément réflecteur peut notamment être une main d'utilisateur. Le capteur 7 est, par exemple, constitué autour d'un circuit émetteur-récepteur de signaux ultrasoniques ou d'un circuit émetteur-récepteur de signaux hyperfréquence, usuel. Il est supposé posséder un axe privilégié de détection de mouvement F, tel que schématisé sur la figure 2. Un traitement des signaux d'évaluation de mouvement, reçus par le capteur envisagé ci-dessus, est effectué au niveau d'une logique de ce capteur ou de la logique de commande 3 en vue de déterminer le sens et, par exemple, la vitesse ou la distance parcourue pour un mouvement détecté. Ceci est réalisé par mise en oeuvre de moyens logiques connus de l'homme de métier. Ces moyens sont, par exemple, localisés au niveau d'une unité de calcul de la logique de commande 3, dûment programmée.The sensor 7, envisaged above, comprises, for example, means to emit signals, for evaluation purposes, and to retrieve them, when they are reflected by an element constituting a reflector which is then located in the sensor field. This reflective element can in particular be a user's hand. The sensor 7 is, for example, constituted around a transceiver circuit for ultrasonic signals or a transceiver circuit of microwave signals, usual. It is supposed to have an axis motion detection system F, as shown diagrammatically in FIG. processing of the motion evaluation signals received by the sensor envisaged above, is carried out at the level of a logic of this sensor or the control logic 3 to determine the direction and, for example, the speed or distance traveled for a detected motion. This is realized by implementing logical means known to those skilled in the art. These means are, for example, located at the level of a unit of calculation of the control logic 3, duly programmed.

    Le système de commande, prend en compte le mouvement d'un élément réflecteur sur le trajet suivi par les ondes émises par le capteur 7, dans une zone délimitée de commande. Comme connu, la délimitation de cette zone est fonction du diagramme de rayonnement prévu à la conception pour le capteur 7, ce diagramme est ici supposé choisi d'allure conique et orienté selon un axe F qui est un axe privilégié de détection pour le capteur. Le cône d'émission du capteur 7 est prévu étroit et de faible extension en longueur, de manière à éviter la prise en compte du mouvement d'un objet, formant écran, en particulier au-dessus du véhicule, à une distance qui n'est pas susceptible de correspondre à la position d'une main d'un utilisateur agissant à des fins de commande.The control system, takes into account the movement a reflective element on the path followed by the waves emitted by the sensor 7, in a delimited control area. As known, the delimitation of this zone is a function of the radiation pattern provided for the design for the sensor 7, this diagram is here assumed to be of conical shape and oriented according to an axis F which is a preferred detection axis for the sensor. The cone the emission of the sensor 7 is provided narrow and of small extension in length, in order to avoid taking into account the movement of an object, forming a screen, in particularly above the vehicle, at a distance that is not likely to match the position of a hand of a user acting for the purpose of ordered.

    Un exemple de positionnement du capteur 7 pour un ouvrant 8, du type ouvrant de coffre d'un véhicule 9, est illustré sur la figure 2. Le capteur 7 y est disposé au-dessous du niveau de l'ouvrant 8-sur le véhicule et, par exemple, au milieu du véhicule sur le pare-chocs 10, voisin de cet ouvrant, ce dernier étant ici supposé s'ouvrir par un mouvement de bascule de bas en haut. Le diagramme de rayonnement D du capteur est verticalement orienté et il est supposé couvrir une zone étroite, d'allure conique s'étalant vers le haut et jouxtant l'ouvrant de coffre. Bien entendu, l'orientation du faisceau émis par le capteur que traduit le diagramme de rayonnement peut être modifiée, suivant les formes et l'orientation de la partie du véhicule où se situe l'ouvrant à commander à distance, ainsi que celles de cet ouvrant. En particulier, il est envisageable d'avoir un faisceau orienté en sens inverse de celui présenté, par exemple si le capteur 7 est fixé en haut du véhicule, au-dessus d'un ouvrant vertical ou quasivertical, et s'il définit une zone de commande située au-dessous de lui qui s'étend sur au moins une partie de la hauteur de cet ouvrant. Il est également possible de disposer le capteur pour que l'axe privilégié F du capteur ne soit qu'approximativement vertical. En effet, comme schématisé sur la figure 1, c'est la composante verticale "y" du mouvement de l'objet formant écran aux ondes émises par le capteur 7 qui est prise en compte par la logique 3, pour déterminer si la composante du mouvement selon l'axe vertical correspond à un mouvement prédéterminé caractéristique d'une action de commande exécutée par un utilisateur, comme schématisé sur la figure 2, pour un mouvement d'un objet écran qui est symbolisé par une flèche M., dans un plan vertical x, y.An example of positioning of the sensor 7 for an opening 8, of the opening type trunk of a vehicle 9, is shown in Figure 2. The sensor 7 is disposed there below the level of the opening 8-on the vehicle and, for example, in the middle of the vehicle on the bumper 10, adjacent to this opening, the latter being here supposed to open by a rocking movement from bottom to top. The diagram D radiation of the sensor is vertically oriented and is supposed to cover a narrow zone, with a conical shape spreading upwards and adjoining the opening of chest. Of course, the orientation of the beam emitted by the sensor that translates the radiation pattern can be modified, depending on the shapes and the orientation of the part of the vehicle where the door is located to be controlled at distance, as well as those of this opening. In particular, it is possible to have a beam oriented in the opposite direction to that presented, for example if the sensor 7 is fixed at the top of the vehicle, above a vertical or quasivertical opening, and if he defines a control area below him that extends over at least a portion of the height of this opening. he is also possible to arrange the sensor so that the preferred axis F of the sensor is not approximately vertical. Indeed, as shown schematically in Figure 1, it is the vertical component "y" of the movement of the screen forming object to the waves transmitted by the sensor 7 which is taken into account by the logic 3, for determine whether the component of motion along the vertical axis corresponds to a predetermined movement characteristic of a command action executed by a user, as shown diagrammatically in FIG. 2, for a movement of a screen object which is symbolized by an arrow M., in a vertical plane x, y.

    Dans une forme donnée de mise en oeuvre, il est prévu que le mouvement de main permettant de commander l'ouverture de bas en haut de l'ouvrant de coffre 8, schématisé sur la figure 2, corresponde à un mouvement réalisé de bas en haut dans la zone de commande d'orientation verticale que délimite le capteur 7 Ce capteur est ici supposé placé à la partie supérieure du pare-chocs 10. La réalisation d'un tel mouvement ne correspond pas à une action habituelle d'un utilisateur à ce niveau, en l'absence d'un système de commande selon l'invention. Elle se traduit par une composante verticale selon l'axe privilégié du capteur 7 qui est prise en compte si elle correspond à un mouvement prédéterminé, selon cet axe.In a given form of implementation, it is expected that the movement of hand to control the opening from bottom to top of the boot lid 8, schematized in FIG. 2, corresponds to a movement made from below in high in the vertical orientation control area delimited by the sensor 7 This sensor is here supposed to be placed at the upper part of the bumper 10. realization of such a movement does not correspond to a usual action of a user at this level, in the absence of a control system the invention. It results in a vertical component according to the privileged axis of the sensor 7 which is taken into account if it corresponds to a movement predetermined, along this axis.

    Un mouvement de main en sens inverse du précédent peut éventuellement être exploité pour commander la fermeture de l'ouvrant par le mécanisme 1, lorsque celui-ci est prévu pour réaliser de telles opérations d'ouverture/ fermeture.gA hand movement in the opposite direction of the previous one may possibly be operated to control the closing of the sash by the mechanism 1, when this one is planned to realize such operations of opening / closing.

    La mise en service du système de commande selon l'invention peut éventuellement être conditionnée par la détection d'un utilisateur au voisinage de l'ouvrant. Ceci peut être obtenu par utilisation d'un système de détection équipant par ailleurs le véhicule et, par exemple, d'un système de détection d'obstacles par ultrasons utilisé pour l'aide au parcage du véhicule.The commissioning of the control system according to the invention can possibly be conditioned by the detection of a user in the neighborhood of the opening. This can be achieved by using a detection system also equipping the vehicle and, for example, a detection system ultrasonic obstacles used for vehicle parking assistance.

    Il est aussi prévu que la coopération d'un système d'accès "mains libres" avec un système de commande, selon l'invention, au niveau d'un véhicule permette de ne réaliser une commande d'ouvrant à distance, par détection d'un mouvement défini à proximité d'un ouvrant, que si le système d'accès a déterminé la présence à proximité du véhicule d'un utilisateur autorisé disposant d'un identifiant approprié. Les actions des différents systèmes de commande de détection et de contrôle d'accès évoqués ci-dessus peuvent bien entendu être coordonnées de différentes manières, en fonction des besoins des utilisateurs, dans la mesure où la programmation des logiques qui les supervisent est prévue à cet effetIt is also expected that the cooperation of a "hands-free" access system with a control system, according to the invention, at the level of a vehicle allows to perform a remote opening command, by detecting a movement defined close to an opening, that if the access system has determined the presence in the vicinity of the vehicle of an authorized user having an appropriate identifier. The actions of the various control systems of detection and access control mentioned above can of course be coordinates in different ways, according to user needs, insofar as the programming of the logic that supervises them is provided for this purpose

    Une variante de réalisation est illustrée sur la figure 3, en liaison avec un ouvrant de coffre 8' pourvu d'un mécanisme actionneur 1' et équipant un véhicule 9' semblable à celui schématisé sur la figure 2.An alternative embodiment is illustrated in FIG. 3, in connection with a trunk opening 8 'provided with an actuator mechanism 1' and equipping a 9 'vehicle similar to that shown schematically in Figure 2.

    Le véhicule 9' est équipé d'un système de commande qui correspond fonctionnellement à celui défini en liaison avec la figure 1 et qui comporte deux capteurs de mouvement 7A' et 7B'. Ces capteurs permettent de détecter un mouvement d'un élément réflecteur et en particulier d'une main d'un utilisateur, dans une zone de commande délimitée à proximité d'un ouvrant, afin de déterminer si ce mouvement correspond à une action de commande exécutée par l'utilisateur. Les capteurs 7A' et 7B' sont alignés le long de l'ouvrant, par exemple, sur le pare-chocs 10' s'étendant horizontalement sur la caisse du véhicule au-dessous de cet ouvrant. Ils sont disposés de manière que leurs diagrammes de rayonnement respectifs se recoupent symétriquement au long de l'ouvrant. Dans la réalisation présentée sur la figure 3, les deux capteurs sont disposés de manière que leurs axes privilégiés respectifs FA' et FB', symétriquement inclinés l'un vers l'autre, soient dans un même plan, par exemple vertical, perpendiculaire au plan longitudinal médian du véhicule où ils se recoupent. La logique de commande, qui les supervise, est par exemple programmée pour ne déclencher une action de commande que si elle détermine qu'il y a égalité de valeur et identité de sens pour la composante verticale de vitesse de déplacement obtenue à partir des mesures provenant d'un capteur et pour celle obtenue à partir des mesures effectuées par l'autre capteur.The vehicle 9 'is equipped with a corresponding control system functionally to that defined in connection with Figure 1 and which comprises two motion sensors 7A 'and 7B'. These sensors make it possible to detect a movement of a reflective element and in particular of a hand of a user, in a delimited control zone near an opening, in order to determine if this movement corresponds to a command action executed by the user. The sensors 7A 'and 7B' are aligned along the opening, by example, on the bumper 10 'extending horizontally on the body of the vehicle below this opening. They are arranged so that their respective radiation patterns symmetrically overlap in the long of the opening. In the embodiment shown in FIG. 3, the two sensors are arranged so that their respective preferred axes FA 'and FB', symmetrically inclined towards each other, are in the same plane, by vertical example, perpendicular to the median longitudinal plane of the vehicle where they overlap. The control logic, which supervises them, is for example programmed to trigger a control action only if it determines that there is equality of value and sense of meaning for the vertical component of displacement velocity obtained from measurements from a sensor and for that obtained from the measurements made by the other sensor.

    Dans une forme préférée de réalisation, la disposition des capteurs du système de commande, tels 7A' et 7B', sur le véhicule équipé et, en particulier, l'orientation de leurs axes privilégiés respectifs FA', FB' déterminent l'orientation d'un axe résultant R' selon lequel est pris en compte un mouvement, détecté par l'ensemble que ces capteurs forment, pour déterminer si ce mouvement correspond à un mouvement prédéterminé de commande. Cet axe résultant R' est supposé d'orientation verticale dans l'exemple présenté sur la figure 3, une autre orientation peut bien entendu être choisie en fonction des besoins, cette orientation étant par exemple oblique, ou encore horizontale comme envisagé pour la réalisation illustrée sur la figure 6.In a preferred embodiment, the arrangement of the sensors of the system such as 7A 'and 7B' on the equipped vehicle and, in particular, the orientation of their respective priority axes FA ', FB' determine the orientation of a resulting axis R 'according to which a motion is taken into account, detected by the set that these sensors form, to determine if this movement corresponds to a predetermined command movement. This resulting axis R ' is assumed to be vertically oriented in the example shown in Figure 3, a other orientation can of course be chosen according to the needs, this orientation being, for example, oblique, or horizontal as envisaged for the embodiment illustrated in Figure 6.

    Dans l'exemple de mise en oeuvre illustré sur la figure 3, chacun des capteurs associés à un ouvrant, dans un système de commande selon l'invention, effectue des mesures dans la zone limitée qui est définie par son diagramme d'émission. La logique de commande, qui supervise ces capteurs, est, par exemple, programmée pour déclencher une action de commande, en prenant pour critère une ou des conditions de vitesse donnée(s), pour le mouvement déterminé selon l'axe résultant R' , à partir des signaux fournis par chaque capteur à la logique, en cas de détection d'un même mouvement par ces capteurs.In the exemplary implementation illustrated in FIG. 3, each of the sensors associated with an opening, in a control system according to the invention, makes measurements in the limited area that is defined by its diagram resignation. The control logic, which supervises these sensors, is, by example, programmed to trigger a command action, taking for criterion one or more speed conditions, for the movement determined according to the resulting axis R ', from the signals supplied by each sensor to the logic, in case of detection of the same movement by these sensors.

    De manière analogue dans l'exemple de mise en oeuvre illustré sur la figure 2, la logique de commande est programmée pour déclencher une action de commande en prenant pour critère une ou des conditions de vitesse donnée(s), pour le mouvement déterminé selon l'axe privilégié F du capteur 7, à partir des signaux fournis par ce capteur, en cas de détection d'un mouvement d'un élément, et en particulier d'une main, par ce capteur.In a similar manner in the exemplary implementation illustrated in FIG. the control logic is programmed to trigger an action of control by taking as criterion one or more given speed conditions, for the movement determined according to the preferred axis F of the sensor 7, from the signals provided by this sensor, in case of detection of a movement of a element, and in particular with one hand, by this sensor.

    Le déclenchement d'une action au niveau du mécanisme actionneur par un système de commande selon l'invention peut par exemple être obtenu, dès que la vitesse du mouvement déterminée par la logique dépasse une valeur de seuil minimal prédéterminée. Des actions d'ouverture ou de fermeture d'ouvrant peuvent ainsi être obtenues, suivant les besoins, en fonction du sens de mouvement constaté par l'intermédiaire du ou des capteurs.The triggering of an action at the actuator mechanism by a control system according to the invention can for example be obtained, as soon as the speed of movement determined by the logic exceeds a threshold value predetermined minimum. Actions opening or closing of opening can be obtained, depending on the needs, depending on the direction of movement detected through the sensor (s).

    Dans une autre forme de mise en oeuvre, la logique de commande qui supervise le ou les capteurs est programmée pour exploiter la distance parcourue, telle que déterminée selon l'axe privilégié, tel F, d'un capteur unique ou selon l'axe résultant, tel R', dans le cas d'un ensemble de capteurs associés à un même ouvrant, en tant que critère, pour la commande du mécanisme actionneur de cet ouvrant. Pour éviter une commande intempestive par un utilisateur, il est prévu, dans une forme de réalisation, de ne déclencher une commande qu'à partir du moment où l'amplitude du mouvement détecté dépasse une valeur minimale de seuil déterminée. Il est aussi prévu d'exploiter le critère de distance parcourue pour contrôler l'ouverture angulaire d'un ouvrant pivotant, tel que l'ouvrant 11 du véhicule illustré en figure 4, ou l'étendue de sa course dans le cas d'un ouvrant coulissant, tel que l'ouvrant 12 du véhicule présenté en figure 6, de manière à permettre une ouverture ou une fermeture partielle. Une ouverture d'ouvrant, proportionnelle à la distance parcourue par une main dans un sens de mouvement prédéterminé, peut ainsi être obtenue pour une commande donnée.In another form of implementation, the control logic that supervises the sensor or sensors is programmed to exploit the distance traveled, such that determined according to the privileged axis, such as F, of a single sensor or along the axis resulting, as R ', in the case of a set of sensors associated with the same opening, as a criterion, for the control of the actuator mechanism of this opening. To avoid an untimely command by a user, it is provided, in one embodiment, to trigger an order only from the moment the detected motion amplitude exceeds a minimum value of threshold determined. It is also planned to exploit the criterion of distance traveled to control the angular opening of a pivoting opening, such as the opening 11 of the vehicle illustrated in FIG. 4, or the extent of its travel in the case of an opening sliding, such as the opening 12 of the vehicle shown in Figure 6, so as to allow partial opening or closing. An opening of opening, proportional to the distance traveled by a hand in a direction of predetermined movement, can thus be obtained for a given command.

    Comme il est connu, le déplacement d'un élément, dans la zone de commande définie par un ou des capteurs, peut être déterminé à partir de mesures de vitesse réalisées à partir de signaux impulsionnels ou encore de mesures de type Doppler réalisées à partir d'ondes émises en continu. La détermination de la trajectoire suivie en cours de déplacement peut aussi éventuellement être réalisée par une corrélation de la vitesse de l'objet faisant écran avec sa distance par rapport au capteur.As it is known, moving an element in the control zone defined by one or more sensors, can be determined from measurements of velocity generated from pulse signals or Doppler type made from waves emitted continuously. The determination of the trajectory followed during the trip may also be achieved by a correlation of the velocity of the object making screen with its distance to the sensor.

    Les figures 4 et 5 sont relatives à une mise en oeuvre de l'invention, au niveau d'un véhicule comportant un ouvrant 11 pivotant, où il est prévu un capteur de mouvement 13 supposé positionné au niveau d'une poignée de manoeuvre que comporte cet ouvrant. Le capteur 13 est monté de manière que son axe privilégié de détection F soit orientée de manière à détecter des mouvements effectués au moins à peu près verticalement par un utilisateur par exemple au moyen d'une main dans la zone de commande qui correspond au diagramme de rayonnement de ce capteur. Dans l'exemple théorique donné, ce diagramme d'allure approximativement ellipsoïdal ou ovoïdal est orienté vers le haut selon l'axe privilégié F du capteur, comme schématisé, de manière à prendre en compte les mouvements d'un élément réflecteur et en particulier d'une main dans une zone de commande située au-dessus du capteur 13 et s'écartant extérieurement et progressivement de l'ouvrant 11, vers le haut de cet ouvrant 11 qu'elle jouxte.FIGS. 4 and 5 relate to an implementation of the invention, at the level of of a vehicle comprising an opening 11 pivoting, where there is provided a sensor of movement 13 supposed positioned at a maneuvering handle that includes this opening. The sensor 13 is mounted so that its axis Preferred Detection F is oriented to detect motion carried out at least approximately vertically by a user for example at means of a hand in the control zone that corresponds to the diagram of radiation of this sensor. In the theoretical example given, this diagram of approximately ellipsoidal or ovoidal shape is oriented upwards according to the preferred axis F of the sensor, as shown schematically, so as to take account the movements of a reflective element and in particular of a hand in a control zone located above the sensor 13 and moving away outwardly and progressively from the opening 11, upwards of this opening 11 that it is adjacent.

    La figure 6 est relative à une mise en oeuvre de l'invention, au niveau d'un véhicule comportant un ouvrant coulissant 12 et au moins un capteur de mouvement 14, ici supposé fixé sur une paroi latérale du véhicule au long de laquelle coulisse l'ouvrant. Le capteur 14 est monté de manière que son axe privilégié de détection F soit orienté de manière à détecter des mouvements effectués au moins à peu près horizontalement par un utilisateur par exemple au moyen d'une main dans la zone de commande qui correspond au diagramme de rayonnement de ce capteur. Dans une forme-préférée de réalisation, l'orientation du capteur ou éventuellement des capteurs du système de commande associé à cet ouvrant coulissant, est choisie pour assurer une détection des mouvements s'effectuant dans au moins un des sens correspondant respectivement au sens d'ouverture ou de fermeture de l'ouvrant.FIG. 6 relates to an implementation of the invention, at the level of a vehicle comprising a sliding leaf 12 and at least one movement 14, here supposed to be fixed on a side wall of the vehicle along which slides the opening. The sensor 14 is mounted so that its axis privileged F detection is oriented to detect movements performed at least approximately horizontally by a user for example by means of a hand in the control zone that corresponds to the diagram of this sensor. In a preferred embodiment, the orientation of the sensor or possibly the sensors of the system of control associated with this sliding leaf, is chosen to ensure a motion detection in at least one of the senses respectively corresponding to the opening or closing direction of the opening.

    Ceci afin de permettre à l'utilisateur de commander le coulissement de l'ouvrant par un mouvement de main effectué, le long du véhicule et à proximité de l'ouvrant, dans le sens de mouvement désiré pour l'ouvrant.This is to allow the user to control the sliding of the opening by a movement of the hand, along the vehicle and near opening it, in the desired direction of movement for the opening.
