Description

La présente invention concerne le domaine des écrans mobiles motorisés, notamment de protection solaire, de type store et notamment store banne, ou équivalent, destinés à équiper des baies d'un bâtiment.The present invention relates to the field of motorized mobile screens, including sun protection, store-type awning and especially awning, or equivalent, intended to equip the bays of a building.

Elle concerne plus particulièrement un procédé de commande d'une installation de store motorisée, l'installation comprenant un châssis supportant un tube d'enroulement apte à être entraîné en rotation par un actionneur comprenant un moteur tubulaire permettant à une toile de store d'être enroulée ou déroulée autour du tube par une première extrémité, la toile de store étant fixée par une seconde extrémité à une barre de charge disposée sensiblement parallèlement au tube d'enroulement et montée mobile par rapport au châssis entre des positions de fin de course respectivement enroulée et déroulée de la toile par l'intermédiaire de bras dépliables, le procédé comprenant, lors du déroulement de la toile, une étape de commande de l'actionneur propre à amener la toile dans une position de fin de course déroulée tendue.It relates more particularly to a control method of a motorized blind system, the installation comprising a frame supporting a winding tube adapted to be rotated by an actuator comprising a tubular motor allowing a shade cloth to be wound or unrolled around the tube by a first end, the blind fabric being fixed by a second end to a load bar disposed substantially parallel to the winding tube and mounted movably relative to the frame between end positions respectively rolled up and unrolled from the fabric by means of foldable arms, the method comprising, during the unfolding of the fabric, a step of controlling the actuator capable of bringing the fabric into a stretched stretched end position.

Lorsque le store est replié, toute la toile est enroulée, les bras sont repliés et la barre de charge vient en contact avec le châssis du store. Lors du déploiement, le moteur entraîne le tube d'enroulement en rotation et les bras de guidage se déplient progressivement jusqu'à une position de verrouillage des bras, correspondant à la position de fin de course déroulée de la toile, dans laquelle elle est tendue.When the blind is folded, all the fabric is rolled up, the arms are folded and the load bar comes into contact with the blind frame. During deployment, the motor drives the winding tube in rotation and the guide arms unfold gradually to a locked position of the arms, corresponding to the end position of the unwinding of the fabric, in which it is tensioned .

D'une manière classique, l'actionneur tubulaire entraînant en rotation le tube d'enroulement afin de placer le store dans des positions de fin de course respectivement déroulée ou enroulée, est associé à un dispositif de fin de course permettant d'arrêter l'actionneur lorsque le store se trouve complètement déroulé ou enroulé. Un tel dispositif comporte généralement un dispositif de comptage des tours d'enroulement de la toile autour du tube d'enroulement pour permettre de déterminer les positions de fin de course. Ainsi, le dispositif de comptage associé à l'actionneur permet de connaître à tout moment la position courante de la barre de charge et, au cours d'une phase de réglage, on mémorise les deux positions de fin course enroulée et déroulée. Pour ce faire, l'utilisateur manoeuvre le store par petit pas dans les deux sens de rotation jusqu'à atteindre les positions de fin de course idéales souhaitées et les mémorise. Aux cycles de fonctionnement suivant, l'actionneur est commandé pour s'arrêter automatiquement sur les positions de fin de course ainsi mémorisées. Une contrainte particulière pèse sur la détermination de la position de fin de course déroulée du store, qui doit être réglée précisément afin de garantir une tension de toile déroulée optimale. En effet, il est nécessaire dans cette position complètement déployée du store que la toile soit bien tendue, à la fois pour des raisons esthétiques et techniques (absence d'accumulation d'eau en cas de pluie, maintien plus rigide et donc résistance au vent, etc.). Or, il apparaît qu'une telle précision est difficile à obtenir compte tenu des variations de longueur de la toile constatées dans le temps. Ainsi, au cours de l'utilisation du store, la toile peut s'allonger légèrement, ce qui aura pour effet de provoquer un effet de toile détendue en position de fin de course déroulée.In a conventional manner, the tubular actuator rotating the winding tube in order to place the blind in respectively unwound or wound end-of-travel positions, is associated with an end-of-stroke device for stopping the winding. actuator when the blind is fully unwound or rolled up. Such a device generally comprises a device for counting the winding turns of the fabric around the winding tube to allow determination of the end positions. Thus, the counting device associated with the actuator makes it possible to know at any time the current position of the load bar and, during a setting phase, the two wound end positions are recorded wound up and unwound. To do this, the user operates the blind in small steps in both directions of rotation until reaching the ideal end positions desired and memorizes them. At subsequent operating cycles, the actuator is controlled to automatically stop at the end positions thus stored. A particular constraint weighs on the determination of the unwound end position of the blind, which must be precisely adjusted in order to guarantee an optimal unwound fabric tension. Indeed, it is necessary in this fully deployed position of the awning that the fabric is well tensioned, both for aesthetic and technical reasons (absence of water accumulation in case of rain, maintaining more rigid and therefore wind resistance , etc.). However, it appears that such precision is difficult to obtain given the variations in length of the fabric observed over time. Thus, during the use of the awning, the fabric may lengthen slightly, which will have the effect of causing a relaxed canvas effect in the unwinding end position.

On connaît déjà des dispositifs de commande d'installation de store motorisée permettant de placer de façon sûre le store dans une position toile tendue en fin de course de déroulement.Motorized blind installation control devices are already known for securely placing the blind in a stretched canvas position at the end of the unwinding run.

Ainsi, le document FR 2 899 923 fait connaître un procédé de commande d'une installation de store basée sur une détection de la chute de tension de toile lorsque les bras dépliables de guidage de la toile sont dans une position complètement dépliée, suivi d'un léger mouvement d'enroulement de la toile sur le tube en réponse à la détection de cette chute de tension de la toile, cette étape d'enroulement étant stoppée automatiquement avant un repli perceptible des bras. Le fait de déclencher l'étape d'enroulement dès que la tension de la toile chute permet ainsi de retendre automatiquement la toile, sans qu'il soit nécessaire de recourir à des dispositifs de comptage pour commander l'arrêt du déploiement de la toile. Toutefois, ce mode commande du store pour amener la toile dans une position de fin de course déroulée tendue est relativement complexe à mettre en oeuvre, puisqu'elle nécessite un léger mouvement de repliement du store pour retendre la toile.Thus, the document FR 2,899,923 discloses a method of controlling a blind installation based on a detection of the web tension drop when the foldable guide arms of the fabric are in a fully unfolded position, followed by a slight winding movement of the fabric. canvas on the tube in response to the detection of this voltage drop of the fabric, this winding step being stopped automatically before a noticeable withdrawal of the arms. The fact of triggering the winding step as soon as the tension of the fabric drops thus makes it possible to automatically tighten the fabric, without it being necessary to resort to counting devices to control the stopping of the deployment of the fabric. However, this control mode blind to bring the canvas in a stretched stretched end position is relatively complex to implement, since it requires a slight folding movement of the blind to tighten the fabric.

Le document FR 2 816 465 fait connaître un procédé de commande d'un store basé sur la détermination d'une valeur maximale de couple exercé sur le moteur lors de la fin de course de déroulement du store, cette valeur correspondant à une valeur de seuil de déroulement pour laquelle le store occupe une position de fin de course déroulée tendue, puis on détecte le couple exercé sur le moteur lors du déploiement et, en cas de dépassement de la valeur de seuil de déroulement, on arrête le moteur en déroulement et on le commande en enroulement jusqu'à ce que la valeur de couple détecté dépasse à nouveau la valeur de seuil de déroulement. Ce mode de commande implique donc également un mouvement de repliement de la toile après l'arrêt du moteur pour s'assurer que le store occupe une position déroulée tendue en fin de course déroulée.The document FR 2 816 465 discloses a method of controlling a blind based on the determination of a maximum torque value exerted on the motor at the end of the unwinding course of the blind, this value corresponding to a unwinding threshold value for which the blind occupies a stretched end position and then detects the torque exerted on the motor during deployment and, if the unwinding threshold value is exceeded, the motor is stopped unwinding and it is commanded in winding until the detected torque value again exceeds the value of unwinding threshold. This control mode therefore also involves a folding movement of the fabric after stopping the motor to ensure that the blind occupies a stretched position stretched at the end of the unwound race.

Aussi, un but de l'invention est de fournir un procédé de commande d'une installation de store motorisée permettant de placer, de manière simple et reproductible, la toile dans une position tendue en fin de course de déroulement.Also, an object of the invention is to provide a control method of a motorized blind system for placing, in a simple and reproducible manner, the fabric in a stretched position at the end of unwinding run.

A cette fin, l'invention concerne un procédé de commande d'une installation de store motorisée, l'installation comprenant un châssis supportant un tube d'enroulement apte à être entraîné en rotation par un actionneur comprenant un moteur d'entraînement tubulaire permettant à une toile de store d'être enroulée ou déroulée autour du tube par une première extrémité, la toile de store étant fixée par une seconde extrémité à une barre de charge disposée sensiblement parallèlement au tube d'enroulement et montée mobile par rapport au châssis entre des positions de fin de course respectivement enroulée et déroulée de la toile par l'intermédiaire de bras dépliables, le procédé comprenant, lors du déploiement de la toile, une étape de commande de l'actionneur propre à amener la toile dans une position de fin de course déroulée tendue, le procédé étant caractérisé en ce qu'il comprend une phase de réglage comprenant :

  • lors du déploiement de la toile, une étape de surveillance de la vitesse de rotation du moteur ou du couple moteur,
  • une étape de détection d'une augmentation de la vitesse de rotation du moteur ou du couple moteur, consécutive à un mouvement de dépliement des bras en fin de déploiement précédant l'arrivée des bras dans une position de verrouillage des bras, l'arrêt du déploiement étant déclenché automatiquement en réponse à la détection de l'augmentation de vitesse de rotation du moteur ou du couple moteur ;

En référence à la figure 1, une installation de store motorisée 1 conforme à l'invention est une installation de type « store banne », utilisé typiquement comme protection solaire des terrasses. Sur un châssis 2, destiné à être fixé sur une structure telle qu'une façade d'un bâtiment, est fixé un tube d'enroulement 3 sur lequel est destiné à venir s'enrouler une toile 4 par une de ses extrémités. L'autre extrémité de la toile 4 est fixée à une barre de charge 5, retenue au châssis 2 par au moins deux bras dépliables 6, 7 permettant de guider la barre de charge 5 et assurant la tension de la toile 4, lors des opérations de déroulement et d'enroulement de la toile. Les bras 6, 7 sont fixés d'une part, au châssis et, d'autre part, à la barre de charge et présentent au moins un coude articulée leur permettant de se plier ou de se déplier pour accompagner un mouvement de repli ou de déploiement de la toile. Les bras sont munis, généralement au niveau du coude d'un ressort (non représenté) sollicité lors de l'enroulement de la toile.With reference to the figure 1 , a motorized blind system 1 according to the invention is a type of installation "awning", typically used as solar protection of the terraces. On a frame 2, intended to be fixed on a structure such as a facade of a building, is fixed a winding tube 3 on which is intended to come to wind a fabric 4 by one of its ends. The other end of the fabric 4 is attached to a load bar 5, held in the frame 2 by at least two folding arms 6, 7 for guiding the load bar 5 and ensuring the tension of the fabric 4, during operations unwinding and winding the canvas. The arms 6, 7 are fixed on the one hand to the chassis and, on the other hand, to the load bar and have at least one articulated elbow allowing them to fold or unfold to accompany a folding movement or deployment of the canvas. The arms are provided, generally at the elbow of a spring (not shown) biased during the winding of the fabric.

Un actionneur comprenant un moteur tubulaire 8 est monté à l'intérieur du tube d'enroulement 3. Cet actionneur est apte à entraîner le tube 3 en rotation dans un premier sens et, en alternance, dans un deuxième sens opposé, de manière à permettre d'enrouler ou de dérouler la toile 4. Conformément à l'invention, l'actionneur comprend également un capteur de vitesse apte à mesure la vitesse de rotation du moteur. Comme on le verra plus en détail par la suite, se sont les variations de cette grandeur qui permettront de commander l'installation 1 lors d'une phase de réglage de cette dernière visant à déterminer la position de fin de course déroulée de la toile. Toutefois, le moteur étant entraîné en conséquence de l'effort exercé par les bras, on pourra utiliser de manière équivalente une mesure du couple perçu par le moteur pendant la phase de déploiement. Aussi, un capteur permettant de mesurer le couple moteur pendant le déploiement pourra être utilisé tout en restant dans le cadre de l'invention.An actuator comprising a tubular motor 8 is mounted inside the winding tube 3. This actuator is able to drive the tube 3 in rotation in a first direction and, alternately, in a second opposite direction, so as to allow 4. In accordance with the invention, the actuator also comprises a speed sensor capable of measuring the speed of rotation of the motor. As will be seen in more detail later, are variations of this magnitude that will control the installation 1 during an adjustment phase of the latter to determine the end position of the unwinding of the fabric. However, the engine being driven as a result of the force exerted by the arms, it will be possible to use an equivalent measurement of the torque perceived by the engine during the deployment phase. Also, a sensor for measuring the engine torque during deployment can be used while remaining within the scope of the invention.

Enfin, l'actionneur est piloté par l'intermédiaire d'une unité de commande apte à exécuter le procédé de commande qui sera décrit en référence à la figure 3. Cette unité de commande est typiquement constituée d'un calculateur programmable associé à un support d'enregistrement d'informations contenant des instructions pour l'exécution du procédé.Finally, the actuator is controlled via a control unit capable of executing the control method which will be described with reference to FIG. figure 3 . This control unit typically consists of a programmable computer associated with an information recording medium containing instructions for the execution of the method.

Lorsque le store est replié, toute la toile 4 est enroulée autour du tube d'enroulement 3, les bras 6, 7 sont repliés et la barre de charge 5 vient en contact avec le coffre ou le support de store (non représenté).When the blind is folded, all the fabric 4 is wrapped around the winding tube 3, the arms 6, 7 are folded and the load bar 5 comes into contact with the trunk or the shade support (not shown).

Classiquement, lors du déploiement, le moteur tubulaire 8 entraîne le tube 3 en rotation de manière à dérouler la toile 4. Les bras 6, 7 se déplient alors progressivement jusqu'à leur longueur maximum correspondant à une position de verrouillage des bras, dans laquelle les bras sont arc-boutés, permettant un bon maintien de la tension de toile. Dans les installations existantes, cette position correspond également à la position de fin de course déroulée, soit à la position complètement déployée, également connue sous les termes de « position de fin de course basse ».Conventionally, during deployment, the tubular motor 8 drives the tube 3 in rotation so as to unroll the fabric 4. The arms 6, 7 then unfold gradually to their maximum length corresponding to a locking position of the arms, in which the arms are braced, allowing a good maintenance of the tension of canvas. In existing installations, this position also corresponds to the unwinding end position, ie to the fully deployed position, also known as the "low end position".

La Figure 2 illustre la variation de la vitesse de rotation du moteur mesurée par le capteur, en fonction du temps, à différentes phases du déploiement du store. Ainsi, lors du déploiement du store, depuis la position de fin de course enroulée, une phase de dépliement progressif des bras permet de dérouler le store avec la toile tendue grâce à l'action des ressorts intégrés dans chaque bras. Dans cette phase, référencée V1 sur la figure 2, où les bras sont en cours d'ouverture et non verrouillés, la vitesse de rotation du moteur mesurée est quasiment constante. Puis, lorsque les bras arrivent en fin de dépliement mais avant d'atteindre leur position de verrouillage, la toile reste tendue et on détecte par l'intermédiaire du capteur une augmentation significative de la vitesse de rotation du moteur jusqu'à l'arrivée des bras dans leur position de verrouillage. Cette phase du déploiement référencée V2 sur la figure 2 où la vitesse de rotation du moteur est en accélération est provoquée par la cinématique des bras lors du déploiement. En effet, en fin de déploiement, lorsque la toile atteint sa position complètement déployée, pendant un court intervalle de temps, l'effort exercé par les bras juste avant d'atteindre leur position de verrouillage est beaucoup plus important, ce qui entraîne une augmentation significative de la vitesse de rotation du moteur. Puis, lorsque les bras atteignent leur position de verrouillage, intervient une troisième phase référencée V3 à la figure 2, dans laquelle le moteur n'est plus entraîné, de sorte qu'il ralentit en déroulant légèrement la toile détendue, ce qui se traduit par une vitesse de rotation du moteur mesurée en décélération, dans la mesure où la toile n'exerce plus de contrainte sur le tube d'enroulement et donc sur l'actionneur. Ainsi, la toile reste tendue jusqu'à la position de verrouillage des bras et elle est ensuite détendue si le moteur continue d'entraîner le tube en rotation.The Figure 2 illustrates the variation of the motor rotation speed measured by the sensor, as a function of time, at different phases of the deployment of the blind. Thus, during the deployment of the blind, from the wrapped end position, a progressive unfolding phase of the arms allows unrolling the awning with the stretched canvas thanks to the action of the springs integrated in each arm. In this phase, referenced V1 on the figure 2 , where the arms are being opened and unlocked, the rotational speed of the measured motor is almost constant. Then, when the arms reach the end of unfolding but before reaching their locking position, the fabric remains taut and detected by means of the sensor a significant increase in the speed of rotation of the engine until the arrival of arm in their locking position. This phase of deployment referenced V2 on the figure 2 where the speed of rotation of the motor is in acceleration is brought about by kinematics of the arms during deployment. Indeed, at the end of deployment, when the fabric reaches its fully deployed position, for a short period of time, the force exerted by the arms just before reaching their locking position is much greater, which causes an increase significant speed of rotation of the engine. Then, when the arms reach their locking position, intervenes a third phase referenced V3 to the figure 2 , in which the motor is no longer driven, so that it slows down by loosening the relaxed fabric slightly, which results in a speed of rotation of the engine measured in deceleration, since the fabric no longer exerts stress on the winding tube and thus on the actuator. Thus, the fabric remains stretched to the locking position of the arms and is then relaxed if the motor continues to drive the tube in rotation.

Aussi, conformément à l'invention, la position dans laquelle on détecte une augmentation de la vitesse de rotation du moteur, consécutive à un mouvement de dépliement des bras en fin de déploiement précédant l'arrivée des bras dans leur position de verrouillage, correspond à la position idéale de fin de course déroulée tendue. La détermination de cette position de fin de course déroulée tendue (fin de course basse) est donc basée sur la détection de l'accélération de la vitesse de rotation du moteur lors du déploiement du store. On commande l'arrêt automatique du moteur et donc le blocage du tube d'enroulement dès que l'augmentation de la vitesse de rotation du moteur est détectée, de sorte que l'installation est à l'arrêt empêchant que l'actionneur ne poursuive le déroulement de la toile, qui reste donc avantageusement tendue dans sa position de fin de course basse.Also, in accordance with the invention, the position in which an increase in the speed of rotation of the motor is detected, following an unfolding movement of the arms at the end of the deployment preceding the arrival of the arms in their locking position, corresponds to the ideal position of end of race unrolled stretched. The determination of this stretched stretched end position (low end of stroke) is therefore based on the detection of the acceleration of the rotational speed of the motor during the deployment of the blind. It controls the automatic shutdown of the motor and therefore the locking of the winding tube as soon as the increase in the rotational speed of the motor is detected, so that the installation is stopped preventing the actuator from continuing the unwinding of the fabric, which therefore remains advantageously taut in its low end position.

Partant de ce principe, un mode d'exécution du procédé va maintenant être décrit en référence à l'organigramme de la figure 3. La détermination de la position de fin de course déroulée tendue est effectuée lors d'une phase de réglage E0 de l'installation. Cette phase de réglage est activée par exemple par l'installateur lors d'une première phase de réglage, au moyen de la transmission d'une commande appropriée à l'actionneur, par exemple à partir d'un point de commande filaire ou sans fil. Lorsque l'entrée dans la phase de réglage est activée, les étapes suivantes sont mises en oeuvre. Le basculement dans la phase de réglage déclenche une étape E01 de déploiement du store depuis la position de fin de course enroulée (fin de course haute) dans laquelle on surveille la vitesse de rotation du moteur mesurée en continu par le capteur lors du déploiement.On the basis of this principle, an embodiment of the method will now be described with reference to the flowchart of the figure 3 . The determination of the stretched stretched end position is performed during an adjustment phase E0 of the installation. This adjustment phase is activated for example by the installer during a first adjustment phase, by means of the transmission of a command appropriate to the actuator, for example from a wired or wireless control point. . When the entry into the adjustment phase is activated, the following steps are implemented. The switchover in the adjustment phase triggers a step E01 of deployment of the blind from the wound end position (high limit switch) in which the rotation speed of the motor measured continuously by the sensor during the deployment is monitored.

Lors d'une étape E02, les bras arrivent en fin d'ouverture mais ne sont pas bloqués, c'est-à-dire qu'ils n'ont pas encore atteint leur position de verrouillage. Peu avant l'arrivée des bras dans leur position de verrouillage, l'unité de commande de l'actionneur détecte une augmentation de la vitesse de rotation du moteur mesurée par le capteur. Pour ce faire, l'unité de commande évalue la vitesse de variation de la vitesse de rotation du moteur au cours du déploiement, et détecte lorsque la vitesse de variation croît dans un intervalle de temps donné, relativement court.During a step E02, the arms arrive at the end of opening but are not blocked, that is to say that they have not yet reached their locking position. Shortly before the arrival of the arms in their locked position, the actuator control unit detects an increase in the rotational speed of the motor measured by the sensor. To do this, the control unit evaluates the rate of change of the rotational speed of the motor during deployment, and detects when the rate of variation increases in a given period of time, relatively short.

En réponse à la détection de l'augmentation de la vitesse de rotation du moteur en fin de déploiement, l'unité de commande, dans une étape E03, commande immédiatement l'arrêt du moteur, le store étant alors considéré être, conformément à l'invention, dans une position correspondant à la position idéale de fin de course déroulée tendue. Suite à cet arrêt, dans une étape E04, l'unité de commande mémorise la position du store lors de l'arrêt du déploiement, par exemple via la position fournie par le dispositif de comptage, la position ainsi mémorisée correspondant à la position de fin de course déroulée tendue qui sera utilisée lors des cycles de fonctionnement suivants.In response to the detection of the increase in the rotational speed of the engine at the end of deployment, the control unit, in a step E03, immediately commands the stopping of the motor, the blind then being considered to be, in accordance with the invention, in a position corresponding to the ideal position stretched stretched end position. Following this stop, in a step E04, the control unit stores the position of the blind when the deployment is stopped, for example via the position supplied by the counting device, the position thus stored corresponding to the end position Tensioned Stroke that will be used in subsequent cycles.

Puis, la phase de réglage se termine par une étape E05 dans laquelle l'unité de commande déclenche le repliement continu du store (sans arrêt) jusqu'à la position de fin de course enroulée. On sort de la phase de réglage et le store est alors opérationnel pour les cycles de fonctionnement suivants, dans lesquels les étapes E1 à E13 sont exécutées.Then, the adjustment phase ends with a step E05 in which the control unit triggers the continuous folding of the blind (without stopping) to the wound end position. We leave the adjustment phase and the blind is then operational for the following operating cycles, in which the steps E1 to E13 are executed.

Ainsi, lorsqu'on bascule dans un cycle de fonctionnement normal du store (étape E1), l'unité de commande, dans une étape E11 commande le déploiement du store, puis, dans une étape E12, lorsque ce dernier atteint la position mémorisée précédemment dans la phase de réglage, l'unité de commande, dans une étape E13, commande l'arrêt automatique du déploiement dans cette position mémorisée, correspondant à la position de fin de course déroulée tendue.Thus, when switching into a normal operating cycle of the blind (step E1), the control unit, in a step E11 controls the deployment of the blind, then, in a step E12, when the latter reaches the previously stored position in the adjustment phase, the control unit, in a step E13, controls the automatic stopping of the deployment in this memorized position, corresponding to the stretched stretched end position.

Au cours de l'utilisation du store, la toile peut s'allonger légèrement, ce qui peut avoir pour effet de créer un effet de toile détendue en position de fin de course déroulée. L'unité de commande est alors prévue pour pourvoir réajuster automatiquement la position de fin de course déroulée périodiquement ou à chaque cycle de fonctionnement en exécutant à nouveau les étapes E01 à E04 de la phase de réglage, de façon transparente pour l'utilisateur. Autrement dit, dans les cas où la détection de position de fin de course déroulée a lieu périodiquement ou à chaque cycle de fonctionnement, c'est-à-dire lors d'une commande de déploiement du store par l'utilisateur, la phase de réglage peut être exécutée à nouveau, mais en excluant alors l'étape E05 de repliement continu du store jusqu'à la position de fin de course enroulée. En effet, le store doit se déployer, détecter la position de fin de course déroulée suivant les principes décrits aux étapes E01 et E02, arrêter automatiquement le moteur à cette position et mémoriser cette nouvelle position en remplacement de la précédente. Le store ne doit pas alors se replier automatiquement suivant l'étape E05 de la phase réglage, car ce n'est pas, dans ce cas de figure, le souhait de l'utilisateur.During the use of the shade, the fabric may lengthen slightly, which may have the effect of creating a relaxed canvas effect in the end position of the fabric. unrolled race. The control unit is then provided to be able to automatically readjust the end of travel position unwound periodically or at each operating cycle by performing again the steps E01 to E04 of the adjustment phase, in a manner transparent to the user. In other words, in the cases where the end position detection is carried out periodically or at each operating cycle, that is to say during a blind deployment command by the user, the phase of adjustment can be performed again, but then excluding step E05 continuous folding of the blind to the wound limit position. Indeed, the awning must deploy, detect the end of travel position unwound according to the principles described in steps E01 and E02, automatically stop the engine at this position and memorize this new position to replace the previous one. The blind must not then fold automatically according to step E05 of the adjustment phase, because it is not, in this case, the wish of the user.
