Description

La présente invention concerne un véhicule automobile comprenant un détecteur d'obstacle pour ouvrants.The present invention relates to a motor vehicle comprising a obstacle detector for openings.

Les véhicules automobiles sont couramment munis de lève-vitres avec un entraínement électrique. Dans ce cas, des normes imposent que la course de la vitre s'interrompe en présence d'un obstacle.Motor vehicles are commonly fitted with window regulators with a electric drive. In this case, standards impose that the race of the window stops when there is an obstacle.

Des solutions pour la détection d'obstacle ont été proposées. Par exemple, le document US-A-5 955 854 décrit un système anti-pincement optique où chaque vitre est dotée d'un système de détection. L'inconvénient de cette solution est qu'elle est onéreuse car elle entraíne la multiplication des systèmes de détection.Solutions for obstacle detection have been proposed. For example, the document US-A-5 955 854 describes an optical anti-pinch system where each window has a detection system. The downside of this solution is that it is expensive because it leads to the multiplication of detection systems.

Il existe donc un besoin d'un système de détection d'obstacle plus simple et moins onéreux.There is therefore a need for a simpler obstacle detection system and less expensive.

Pour cela l'invention propose un véhicule comprenant sur une même face deux ouvrants mobiles, et un unique détecteur d'obstacle pour les deux ouvrants.For this, the invention provides a vehicle comprising on the same face two movable doors, and a single obstacle detector for the two doors.

Selon un mode de réalisation, les ouvrants sont mobiles dans une ouverture commune.According to one embodiment, the opening elements are movable in an opening common.

Selon un mode de réalisation, les ouvrants sont adjacents le long d'un joint d'étanchéité.According to one embodiment, the openings are adjacent along a joint sealing.

Selon un mode de réalisation, le joint d'étanchéité est solidaire de l'ouvrant arrière.According to one embodiment, the seal is integral with the opening back.

Selon un mode de réalisation, les ouvrants sont des ouvrants avant et arrière de la même face du véhicule, le détecteur est au coin avant inférieur de l'ouvrant avant.According to one embodiment, the openings are front and rear openings of the same side of the vehicle, the detector is at the lower front corner of the front door.

Selon un mode de réalisation, les ouvrants sont mobiles chacun dans une ouverture.According to one embodiment, the opening elements are each movable in a opening.

Selon un mode de réalisation, l'ouvrant arrière est mobile selon un mouvement non-linéaire.According to one embodiment, the rear door is movable according to a movement non-linear.

Selon un mode de réalisation, le véhicule comprend un rétroviseur portant le détecteur.According to one embodiment, the vehicle comprises a rearview mirror carrying the detector.

Selon un mode de réalisation, le véhicule comprend un tableau de bord portant le détecteur.According to one embodiment, the vehicle includes a dashboard bearing the detector.

Selon un mode de réalisation, les ouvrants sont mobiles dans leur ouverture respective jusqu'à une ligne de contact de fermeture, le détecteur d'obstacle comportant

  • un capteur de lumière couvrant les lignes de contact de fermeture,
  • un circuit d'analyse temporelle de la lumière reçue par le capteur, le circuit d'analyse étant adapté à comparer la répartition de la lumière reçue par le capteur à une répartition de référence.
According to one embodiment, the opening elements are movable in their respective opening up to a closing contact line, the obstacle detector comprising
  • a light sensor covering the closing contact lines,
  • a time analysis circuit for the light received by the sensor, the analysis circuit being adapted to compare the distribution of the light received by the sensor with a reference distribution.

D'autres caractéristiques et avantages de l'invention apparaítront à la lecture de la description détaillée qui suit des modes de réalisation de l'invention, donnés à titre d'exemple uniquement et en références à la figure unique qui montre une représentation schématique d'une face de véhicule dans lequel l'invention peut être mise en oeuvre.Other characteristics and advantages of the invention will appear on reading the following detailed description of embodiments of the invention, given as example only and with reference to the single figure which shows a schematic representation of a vehicle face in which the invention can be Implementation.

L'invention se rapporte à un véhicule comprenant un unique détecteur d'obstacle pour deux ouvrants mobiles d'une même face du véhicule. Ainsi, le même détecteur détecte un obstacle présent sur le parcours de l'un ou l'autre des ouvrants en mouvement, ce qui permet de réduire les coûts d'installation d'un système de protection contre le pincement.The invention relates to a vehicle comprising a single detector obstacle for two movable openings on the same side of the vehicle. So the same detector detects an obstacle present on the path of one or other of the openings in motion, which reduces the installation costs of a pinch protection.

La figure est une représentation schématique d'une face de véhicule dans lequel l'invention peut être mise en oeuvre. Il s'agit de deux ouvrants mobiles 6, 7, tels que des vitres, d'une même face du véhicule. Le véhicule comprend aussi un unique détecteur 14 d'obstacle pour les deux ouvrants. On entend par face, autant un côté du véhicule que son toit comportant deux ouvrants.The figure is a schematic representation of a vehicle face in which the invention can be implemented. There are two movable openings 6, 7, such as windows, on the same side of the vehicle. The vehicle also includes a unique obstacle detector 14 for the two openings. By face is meant as much a side of the vehicle that its roof comprising two openings.

L'ouvrant 6 peut être l'ouvrant avant dans le sens de la marche avant du véhicule, et l'ouvrant 7, l'ouvrant arrière. La figure montre les parties inférieures 2 et 3 de la carrosserie du véhicule, respectivement sous les ouvrants des portes avant 6 et arrière 7 du véhicule. Les ouvrants sont par exemple rendus mobiles par l'action d'un lève-vitre électrique, de sorte à dégager des ouvertures 4 et 5 par leur mouvement vers les parties inférieures 2 et 3 de la carrosserie ; les bords supérieurs 8 et 9 des ouvrants 6 et 7 sont représentés sur la figure, dans une position proche de la position d'ouverture complète des ouvrants. Le mouvement des ouvrants peut être linéaire ou non. En particulier, le mouvement de l'ouvrant 7 arrière peut être non linéaire, tel que cela est le cas pour des véhicules de type cabriolet. Apparaít en trait gras sur la figure le bord supérieur 10 des ouvertures 4 et 5. Par ailleurs, on a représenté sur la figure un obstacle 12, au voisinage de ce bord supérieur 10.The opening 6 may be the front opening in the forward direction of the vehicle, and the opening 7, the rear opening. The figure shows the lower parts 2 and 3 of the vehicle body, respectively under the openings of the front doors 6 and rear 7 of the vehicle. The openings are for example made mobile by the action of a electric window regulator, so as to free openings 4 and 5 by their movement towards the lower parts 2 and 3 of the body; the upper edges 8 and 9 of sashes 6 and 7 are shown in the figure, in a position close to the position full opening opening. The opening movement can be linear or no. In particular, the movement of the rear leaf 7 may be non-linear, such as that this is the case for convertible type vehicles. Appears in bold lines on the shows the upper edge 10 of the openings 4 and 5. Furthermore, there is shown on the there is an obstacle 12, in the vicinity of this upper edge 10.

Ainsi, un unique détecteur 14 est prévu pour détecter la présence d'un obstacle pour une pluralité d'ouvrants, en l'occurrence pour l'un ou l'autre des ouvrants 6, 7 ; la détection par le détecteur 14 d'un obstacle tel qu'une main lors de la remontée d'un des ouvrants, interrompt le mouvement du lève-vitre, voire, inverse le mouvement. Le détecteur peut être intégré dans un dispositif anti-pincement ; la présence d'un unique détecteur rend moins onéreux l'implantation du dispositif anti-pincement. Lorsque au moins l'un ou l'autre des ouvrants est dans une position dégageant l'une des ouvertures 4, 5, le détecteur 14 balaie cette ouverture pour détecter la présence d'un obstacle. Si le détecteur détecte la présence d'un obstacle alors que l'ouvrant est commandé en fermeture, le mouvement de l'ouvrant est interrompu, voire inversé, pour éviter le pincement de l'obstacle. Les mouvements des ouvrants et leur interruption, voire leur inversion, sont indépendants d'un ouvrant à l'autre.Thus, a single detector 14 is provided to detect the presence of an obstacle for a plurality of openings, in this case for one or other of the openings 6, 7; detection by the detector 14 of an obstacle such as a hand during the ascent of one of the doors, interrupts the movement of the window regulator, or even reverses the movement. The detector can be integrated into an anti-pinch device; the the presence of a single detector makes the installation of the anti-pinch device less expensive. When at least one or the other of the openings is in a position releasing one of the openings 4, 5, the detector 14 scans this opening to detect the presence of an obstacle. If the detector detects the presence of an obstacle while the door is closed, the movement of the door is interrupted, or even reversed, to avoid pinching the obstacle. Movements opening and their interruption, even their reversal, are independent of a opening to the other.

Les parties inférieures 2 et 3 de la carrosserie peuvent être toutes deux des parties inférieures de porte ; les parties inférieures 2 et 3 peuvent être ou non surmontées d'un cadre de vitre. Alternativement, seule la partie inférieure 2 avant est une porte d'un véhicule type « trois portes », la partie inférieure 3 arrière n'étant pas mobile.The lower parts 2 and 3 of the body can both be lower door parts; the lower parts 2 and 3 may or may not be surmounted by a window frame. Alternatively, only the lower part 2 before is a door of a "three door" type vehicle, the lower rear part 3 not being mobile.

Les ouvrants 7, 8 peuvent être mobiles chacun dans une ouverture distincte l'une de l'autre. Les ouvertures sont par exemple séparées par un pied milieu, entre les portes et formant le cadre de carrosserie.The openings 7, 8 can each be movable in a separate opening one from the other. The openings are for example separated by a center leg, between doors and forming the body frame.

De préférence, les ouvrants 7, 8 peuvent être mobiles dans une ouverture commune. Les ouvertures 4 et 5 ne sont alors pas séparées par un pied milieu. Lorsque les ouvrants sont en position rentrée dans les parties inférieures 2 et 3, le véhicule comporte alors une ouverture unique s'étendant le long d'une face du véhicule. Ceci facilite la détection d'un obstacle par le détecteur unique 14 pour les deux ouvrants. Les deux ouvrants 6, 7 peuvent par exemple être adjacents le long d'un joint d'étanchéité 11. Lorsque les ouvrants 6 et 7 sont en position remontée jusqu'au bord supérieur 10, le joint 11 assure la continuité de l'étanchéité entre les deux ouvrants. Le joint Il permet d'assurer l'étanchéité entre les deux ouvrants 6, 7 sans pour autant interférer dans la détection de l'obstacle par le détecteur 14. De préférence, le joint 11 est solidaire de l'ouvrant 7 arrière. Ceci est avantageux lorsque l'ouvrant arrière a un mouvement non linéaire, le joint 11 obturant le passage de vitre au sommet de la partie inférieure 3 lorsque la vitre est escamotée ou basculé dans la partie inférieure.Preferably, the openings 7, 8 can be movable in an opening common. The openings 4 and 5 are then not separated by a center leg. When the doors are in the retracted position in the lower parts 2 and 3, the vehicle then has a single opening extending along one side of the vehicle. This facilitates the detection of an obstacle by the single detector 14 for the two openings. The two openings 6, 7 can for example be adjacent along a seal 11. When the openings 6 and 7 are in the raised position up to the upper edge 10, the seal 11 ensures the continuity of the seal between the two openings. The seal It ensures sealing between the two openings 6, 7 without interfering in the detection of the obstacle by the detector 14. From preferably, the seal 11 is integral with the rear opening 7. This is advantageous when the rear opening has a non-linear movement, the seal 11 closing off the window passage at the top of the lower part 3 when the window is retracted or tilted in the lower part.

Le détecteur est, dans l'exemple de la figure, disposé au niveau du coin avant inférieur de l'ouverture 4, qui correspond sensiblement au point de fixation d'un rétroviseur. La position et l'orientation du détecteur dépendent de celles de la porte avant. Le détecteur étant positionné dans le plan des ouvrants, le réglage du détecteur pour détecter un obstacle en travers de l'ouverture dégagée par l'ouvrant, est facilité. Il est aussi possible de disposer le détecteur au niveau du coin arrière inférieur de l'ouverture 5 ; ceci est en particulier avantageux lorsque le véhicule est de type trois portes car la partie inférieure arrière 3 est immobile rendant la détection par le détecteur indépendante des mouvements de la porte avant. Alternativement, le détecteur peut être porté par le rétroviseur du véhicule. Ainsi, le détecteur est déporté vers l'extérieur du véhicule ce qui permet de diminuer les angles morts dans lesquels le détecteur ne peut détecter la présence d'un obstacle en raison de la présence du pied milieu par exemple. Egalement, il est envisageable que le détecteur soit porté par le tableau de bord du véhicule. L'avantage est de rendre la détection par le détecteur indépendante des mouvements des parties inférieures 2 et 3 lorsque ces parties sont des portes.The detector is, in the example of the figure, arranged at the front corner lower opening 4, which corresponds substantially to the point of attachment of a mirror. The position and orientation of the detector depend on those of the door before. The detector being positioned in the plane of the opening, the detector setting to detect an obstacle across the opening cleared by the opening, is facilitated. It is also possible to place the detector at the lower rear corner of opening 5; this is particularly advantageous when the vehicle is of type three doors because the lower rear part 3 is stationary making detection by the detector independent of the movements of the front door. Alternatively, the detector can be carried by the vehicle rear view mirror. Thus, the detector is deported towards the outside of the vehicle, thereby reducing the blind spots in which the detector cannot detect the presence of an obstacle due to the presence of the middle foot for example. Also, it is possible that the detector is worn by the vehicle dashboard. The advantage is to make detection by the independent detector of the movements of the lower parts 2 and 3 when these parts are doors.

Dans l'hypothèse où le capteur est porté par la partie inférieure 2 qui est l'une des portes avant du véhicule, il peut être avantageux que l'ouverture de la porte bloque le mouvement en fermeture de l'ouvrant 7 arrière. En effet, lorsque la porte avant est ouverte, le champ de vision du détecteur est dévié et ne comporte plus l'ouvrant 7 arrière, ni l'ouverture 5 dégagée par l'ouvrant. La détection de la présence d'un obstacle en travers de l'ouverture 5 n'est alors plus possible et il est donc préférable de bloquer toute commande de remontée de l'ouvrant 7 arrière.In the event that the sensor is carried by the lower part 2 which is one front doors of the vehicle, it may be advantageous for the door to open blocks the closing movement of the rear door 7. Indeed, when the door front is open, the detector's field of vision is deflected and no longer has the rear opening 7, nor the opening 5 released by the opening. Detection of presence of an obstacle across the opening 5 is no longer possible and it is therefore preferable to block any command to raise the rear sash 7.

Le détecteur peut être du type optique. Le détecteur d'obstacle peut comporter un capteur de lumière couvrant les lignes de contact de fermeture et un circuit d'analyse temporelle de la lumière reçue par le capteur, le circuit d'analyse étant adapté à comparer la répartition de la lumière reçue par le capteur à une répartition de référence. La variation dans la répartition de la lumière est représentative de la présence d'un obstacle. Le détecteur "regarde" une surface angulaire ou secteur angulaire 18 sensiblement verticale; cette surface angulaire recouvre la partie de l'ouverture 4 limitée par le bord supérieur 10 d'une part et par une demi-droite 18 issue du détecteur 14 d'autre part. En d'autres termes, le détecteur optique couvre dans le plan de l'ouverture - ou dans le plan des ouvrants 6, 7 - une surface voisine du bord supérieur. Cette surface est celle dans laquelle le pincement doit être détecté; en effet, il n'est pas nécessaire de détecter la présence d'un obstacle au voisinage du bord inférieur des ouvertures 4, 5.The detector can be of the optical type. The obstacle detector may include a light sensor covering the closing contact lines and a circuit for temporal analysis of the light received by the sensor, the analysis circuit being suitable for comparing the distribution of the light received by the sensor with a distribution reference. The variation in the light distribution is representative of the presence of an obstacle. The detector "looks" at an angular surface or sector angular 18 substantially vertical; this angular surface covers the part of the opening 4 limited by the upper edge 10 on the one hand and by a half-line 18 from detector 14 on the other hand. In other words, the optical detector covers in the plane of the opening - or in the plane of the openings 6, 7 - a neighboring surface from the top edge. This surface is that in which the pinch must be detected; indeed, it is not necessary to detect the presence of an obstacle in the vicinity of the lower edge of the openings 4, 5.

Bien entendu, la présente invention n'est pas limitée aux modes de réalisations décrit à titre d'exemple. La détection d'obstacle s'applique non seulement pour des vitres, comme expliqué plus haut, mais aussi pour d'autres types d'ouvrants mobiles, comme par exemple des toits ouvrants à entraínement motorisé.Of course, the present invention is not limited to the embodiments described by way of example. Obstacle detection applies not only for windows, as explained above, but also for other types of mobile windows, like for example sunroofs with motorized drive.
