Description

La présente invention concerne une unité de démarrage pour véhicule automobile.The present invention relates to a starter unit for a motor vehicle.

La plupart des nouveaux véhicules utilise un système de démarrage sans clé ; c'est-à-dire que l'on introduit un identifiant électronique, par exemple sous forme de badge, dans un lecteur qui vérifie un codage électronique et lorsque le badge est correctement identifié, l'unité centrale du véhicule autorise le déverrouillage de la colonne de direction et permet l'allumage des fonctions du véhicule. Dans un deuxième temps, afin de lancer le démarrage du moteur du véhicule, l'utilisateur appuie sur un bouton poussoir.Most new vehicles use a keyless start system; that is to say that an electronic identifier, for example in the form of a badge, is introduced into a reader which verifies electronic coding and when the badge is correctly identified, the central unit of the vehicle authorizes the unlocking of the steering column and allows the ignition of the vehicle functions. In a second step, in order to start the engine start of the vehicle, the user presses a push button.

Ces systèmes présentent l'avantage de ne plus utiliser de codages de type mécanique qui peuvent être facilement copiés, mais également ils améliorent l'ergonomie d'utilisation.These systems have the advantage of no longer using mechanical type encodings that can be easily copied, but also they improve the ergonomics of use.

Par contre, ces systèmes sont relativement coûteux puisqu'ils nécessitent un lecteur de badge, un système de bouton poussoir pour le démarrage et un antivol de direction électrique. De plus ils ne sont proposés que pour des véhicules équipés de système d'ouverture à distance dits sans clé, puisque le codage mécanique par la clé n'existe plus.By cons, these systems are relatively expensive since they require a badge reader, a push button system for starting and an electric steering lock. In addition they are only available for vehicles equipped with remote opening system called keyless, since the mechanical coding by the key no longer exists.

Malheureusement, lorsqu'un constructeur veut proposer, dans une démarche de produits à bas coûts, le véhicule équipé d'un dispositif badge et bouton poussoir dans une version purement mécanique, il doit changer tout le système de démarrage pour passer à un système mécanique classique c'est-à-dire avec un verrou de colonne de direction mécanique muni d'un interrupteur de démarrage. Ceci oblige à changer les coques sous volant, la colonne de direction et l'architecture électrique du véhicule. Ces modifications sont très coûteuses et elles vont à l'encontre du but recherché qui est de proposer un véhicule bas coût.Unfortunately, when a manufacturer wants to offer, in a low-cost product approach, the vehicle equipped with a badge and push button device in a purely mechanical version, it must change the entire starting system to switch to a conventional mechanical system that is, with a mechanical steering column lock with a start switch. This requires changing the shells under the steering wheel, the steering column and the electrical architecture of the vehicle. These modifications are very expensive and they go against the goal of offering a low cost vehicle.

Il serait donc particulièrement intéressant de pouvoir utiliser de la manière la plus économique possible l'architecture existante pour y implanter un interrupteur de démarrage mécanique.It would therefore be particularly interesting to be able to use the existing architecture as economically as possible to implement a mechanical start switch.

Or les interrupteurs de démarrage mécanique fonctionnent par établissement de contact permanent c'est-à-dire que le circuit de démarrage est fermé en permanence tant que l'on a pas coupé le moteur alors que dans les boutons poussoir le circuit est fermé par une impulsion pour le démarrage et une impulsion pour couper le moteur.But the mechanical start switches operate by permanent contact establishment that is to say that the start circuit is permanently closed until the engine is shut down while in the push buttons the circuit is closed by a pulse for starting and a pulse to shut down the engine.

On connaît de l'art antérieur les documents FR 2 427 676 A , GB 1 362 176 A et DE 28 53 681 B1 qui ont trait à des interrupteurs de démarrage conformes au préambule de la revendication indépendante.It is known from the prior art the documents FR 2 427 676 A , GB 1 362 176 A and DE 28 53 681 B1 which relate to starter switches according to the preamble of the independent claim.

La présente invention vise à proposer une telle solution en implantant un interrupteur mécanique dans le logement dédié au bouton poussoir.The present invention aims to provide such a solution by implanting a mechanical switch in the housing dedicated to the push button.

A cet effet, l'invention a pour objet un interrupteur de démarrage pour véhicule automobile selon la revendication 1. L'invention peut comporter en outre une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison :

  • le contour intérieur du deuxième orifice excentré comprend au moins quatre segments, au moins deux segment descendants et moins deux segments montants ;
  • un des au moins deux segments montants et un des au moins deux segments descendants a une distance au centre du contacteur rotatif fixe et un des au moins deux segments montants et un des au moins deux segments descendants a une distance au centre du contacteur rotatif variable ;
  • le au moins un contacteur mobile passe, lors de la rotation du rotor dans le sens des aiguilles d'une montre, d'une position où la au moins une sortie est activée, à une position où la au moins une sortie est désactivée ;
  • le au moins un contacteur mobile passe, lors de la rotation du rotor dans le sens inverse des aiguilles d'une montre, d'une position où la au moins une sortie est activée, à une position où la au moins une sortie est désactivée ;
  • il comprend une deuxième sortie électrique apte à être activée par un deuxième contacteur, ledit deuxième contacteur étant monté fixe sur l'ensemble contacteur rotatif.
To this end, the subject of the invention is a starter switch for a motor vehicle according to claim 1. The invention may further comprise one or more of the following characteristics, taken alone or in combination:
  • the displacement of said at least one contactor is radial;
  • the inner contour of the second eccentric orifice comprises at least four segments, at least two descending segments and minus two rising segments;
  • one of the at least two upstanding segments and one of the at least two downstream segments has a distance from the center of the fixed rotary contactor and one of the at least two upstream segments and one of the at least two downstream segments has a distance from the center of the variable rotary contactor;
  • the at least one movable switch, when rotating the rotor in a clockwise direction, moves from a position where the at least one output is activated to a position where the at least one output is deactivated;
  • the at least one moving switch passes, when the rotor is rotated counterclockwise, from a position where the at least one output is activated, to a position where the at least one output is deactivated;

La figure 1 est une vue éclatée d'un interrupteur de démarrage selon un mode de réalisation préférentiel de l'invention, dans lequel on distingue entre autre un stator 1, un rotor dit à paillettes 2 qui est monté mobile en rotation dans le stator.The figure 1 is an exploded view of a starter switch according to a preferred embodiment of the invention, in which there is inter alia a stator 1, a so-called flake rotor 2 which is rotatably mounted in the stator.

Sur le rotor 2 est fixée une pièce support 3, que l'on appellera ici l'ensemble contacteur rotatif, sur lequel en face intérieure sont montés deux contacteurs 4, 5. Les contacteurs 4, 5, selon le mode de réalisation illustré consistent en des lames métalliques. Un des contacteurs 4 est fixé directement sur l'ensemble contacteur rotatif 3, par exemple par des moyens de collage, de soudage ou de clippage, et l'autre contacteur 5 est porté par un coulisseau 6 monté mobile sur l'ensemble contacteur rotatif 3. Le montage mobile du coulisseau 6 est assuré par un dispositif de guidage illustré par les figures 3 et 4, et se base selon un mode de réalisation non limitatif sur le principe d'une glissière aménagé dans l'ensemble contacteur rotatif 3 dans laquelle l'embase du coulisseau va pouvoir glisser. Comme illustré sur la figure 4, la glissière est dans le sens radial vis-à-vis de l'ensemble contacteur rotatif 3, c'est-à-dire que le coulisseau peut se rapprocher du centre de l'ensemble contacteur rotatif 3 ou s'en éloigner.On the rotor 2 is fixed a support piece 3, which will be called here the rotary contactor assembly, on which inner face are mounted two contactors 4, 5. The contactors 4, 5, according to the illustrated embodiment consist of metal blades. One of the contactors 4 is fixed directly to the rotary contactor assembly 3, for example by means of gluing, welding or clipping, and the other contactor 5 is carried by a slider 6 movably mounted on the rotary switch assembly 3 The movable assembly of the slider 6 is provided by a guiding device illustrated by the Figures 3 and 4 and is based on a non-limiting embodiment on the principle of a slide arranged in the rotary switch assembly 3 in which the base of the slide will be able to slide. As illustrated on the figure 4 , the slide is in the radial direction vis-à-vis the rotary contactor assembly 3, that is to say that the slide can move closer to the center of the rotary switch assembly 3 or away from it.

Les contacteurs 4 et 5 font face à des pistes électriques 7, ici trois, une voie centrale qui correspond à l'alimentation de la batterie +Batt, et deux voies périphériques qui correspondent à deux sorties S1, S2. Suivant la position des contacteurs 4 et 5 par rapport aux pistes 7, on pourra obtenir un signal +Batt sur la sortie S1, ceci lorsque la lame du contacteur 4 fait le pont entre la voie +Batt et S1, et/ou un signal +Batt sur la sortie S2, ceci lorsque la lame du contacteur 5 fait le pont entre la voie +Batt et S2. Dans d'autres modes de réalisation non représentés, les contacteurs 4 et 5 et les pistes 7 peuvent être remplacés par un ensemble dans lequel, les lames 4 et 5 sont remplacées par des éléments en saillie, et les pistes 7 sont remplacées par des micro-interrupteurs actionnés par ces éléments en saillie. Il serait dans ce cas possible d'utiliser seulement deux micro-interrupteurs, un reproduisant la fermeture du circuit +Batt - S1, et l'autre reproduisant la fermeture +Batt - S2.The contactors 4 and 5 face electrical tracks 7, here three, a central channel which corresponds to the power supply of the battery + Batt, and two peripheral channels which correspond to two outputs S1, S2. Depending on the position of the contactors 4 and 5 with respect to the tracks 7, it will be possible to obtain a signal + Batt on the output S1, this when the contactor blade 4 makes the bridge between the channel + Batt and S1, and / or a signal + Batt on the output S2, this when the contactor blade 5 bridges the channel + Batt and S2. In other embodiments not shown, the contactors 4 and 5 and the tracks 7 may be replaced by an assembly in which the blades 4 and 5 are replaced by projecting elements, and the tracks 7 are replaced by micro -switches actuated by these protruding elements. It would be possible in this case to use only two microswitches, one reproducing the closure of the circuit + Batt - S1, and the other reproducing the closure + Batt - S2.

Les pistes électriques 7 sont disposées dans une pièces support 8, que l'on appellera ici l'ensemble contacteur statique, et s'interfacent, en sortie de l'ensemble contacteur statique 8 c'est-à-dire vers l'intérieur du véhicule, avec la connectique électrique du véhicule.The electrical tracks 7 are arranged in a support parts 8, which will be called here the static contactor assembly, and interface, at the output of the static contactor assembly 8 that is to say towards the inside of the vehicle, with the electrical connection of the vehicle.

De manière avantageuse et non limitative, on réalise l'ensemble contacteur statique 8 avec les pistes 7, par surmoulage plastique de l'ensemble contacteur statique 8 sur les pistes 7.Advantageously and non-limitatively, the static contactor assembly 8 is made with the tracks 7, by plastic overmolding of the static contactor assembly 8 on the tracks 7.

Entre l'ensemble contacteur rotatif 3 et le rotor 2, est disposé un couvercle 9. Au centre de ce couvercle 9 est ménagé un orifice par lequel va s'enficher une partie cylindrique centrale 10 de l'ensemble contacteur rotatif 3 s'étendant vers l'extérieur et disposé sur la face extérieur de l'ensemble contacteur rotatif 3. Cette partie cylindrique centrale 10 va pouvoir s'accoupler avec le rotor 2. La partie cylindrique 10 joue le rôle femelle avec sa rainure centrale et le rotor joue le rôle mâle avec une tranche centrale complémentaire à la rainure de la partie cylindrique 10. Il n'est pas nécessaire que le deux éléments soient fixés l'un à l'autre pour que la rotation du rotor 2 entraîne la rotation de l'ensemble contacteur rotatif 3.Between the rotary contactor assembly 3 and the rotor 2, there is a cover 9. In the center of this cover 9 is provided an orifice through which a central cylindrical portion 10 of the rotary contactor assembly 3 extending towards the outside and disposed on the outer face of the rotary contactor assembly 3. This central cylindrical portion 10 will be able to mate with the rotor 2. The cylindrical portion 10 plays the female role with its central groove and the rotor plays the role male with a central slice complementary to the groove of the cylindrical portion 10. It is not necessary that the two elements are fixed to each other so that the rotation of the rotor 2 causes rotation of the rotary switch assembly 3.

Le couvercle 9 vient également s'emboîter sur l'ensemble contacteur statique 8, l'ensemble contacteur rotatif 3 se trouvant ainsi pris en sandwich entre le couvercle 9 et l'ensemble contacteur statique 8.The cover 9 also fits on the static contactor assembly 8, the rotary switch assembly 3 thus being sandwiched between the cover 9 and the static contactor assembly 8.

Enfin, le couvercle 9 présente un autre orifice 11 excentré et présentant un profil courbe. Ce profil courbe de l'orifice 11 va servir de rampe montante et descendante à un doigt 12 du coulisseau 6. Comme illustré sur la figure 2, le doigt 12 est un goujon s'étendant vers l'extérieur du coulisseau sur la face opposée à la face sur laquelle est fixé le contacteur 5. Le déplacement du doigt 12 le long du profil en courbe va entraîner comme on le décrira plus loin le déplacement radial du coulisseau 6.Finally, the cover 9 has another orifice 11 eccentric and having a curved profile. This curved profile of the orifice 11 will serve as a rising and falling ramp to a finger 12 of the slide 6. As shown in FIG. figure 2 , the finger 12 is a stud extending towards the outside of the slider on the face opposite to the face on which the contactor 5 is fixed. The displacement of the finger 12 along the curved profile will result as will be described later. the radial displacement of the slide 6.

De manière connue, un ressort de rappel 13 est disposé entre le stator 1 et le rotor 2. Il permet de ramener automatiquement le rotor 2 dans une position prédéterminée. On décriera plus en détail cet aspect dans la suite de la description.In known manner, a return spring 13 is disposed between the stator 1 and the rotor 2. It makes it possible to automatically return the rotor 2 to a predetermined position. This aspect will be described in more detail later in the description.

Enfin, vers l'extrémité tournée vers l'intérieur du véhicule se trouve le capot 14 qui va s'emboîter sur le stator 1. Cela permet de maintenir ensemble les pièces rotor 2 couvercle 9, ensemble contacteur rotatif 3, contacteur 4 et 5, et ensemble contacteur statique 8 avec les pistes 7. L'emboîtement du capot 14 sur le stator 1 se fait, dans l'exemple de réalisation choisi, par deux pattes venant se clipper sur deux ergots ménagés sur des parois extérieures du stator 1.Finally, toward the end turned towards the inside of the vehicle is the cover 14 which will fit on the stator 1. This makes it possible to hold together the rotor parts 2 cover 9, rotary switch assembly 3, contactor 4 and 5, and static contactor assembly 8 with the tracks 7. The engagement of the cover 14 on the stator 1 is, in the embodiment chosen, by two lugs coming to be clipped on two lugs formed on the outer walls of the stator 1.

On va à présent expliquer, à partir des figures 6 à 13, la cinématique des différentes pièces de l'interrupteur de démarrage selon un mode de réalisation préférentiel.We will now explain, from Figures 6 to 13 , the kinematics of the different parts of the start switch according to a preferred embodiment.

Tout d'abord, tout comme dans les interrupteurs de démarrage connus dans l'état de la technique, le rotor à paillettes 2 ne peut effectuer de mouvement de rotation à l'intérieur du stator 1 que si une clé (non représentée) ayant un profil conforme est introduite dans le rotor 2. C'est le cas standard d'un codage dit purement mécanique.First of all, as in the starter switches known in the state of the art, the flake rotor 2 can make rotational movement inside the stator 1 only if a key (not shown) having a Conformal profile is introduced into the rotor 2. This is the standard case of a so-called purely mechanical coding.

Bien entendu, dans d'autres modes de réalisation non représentés ici, on peut intégrer, comme il est connu dans l'état de la technique, une antenne transpondeur à l'interrupteur de démarrage afin d'ajouter au codage mécanique un codage électronique. On peut également par ce biais supprimer le codage mécanique de la clé et ainsi s'affranchir des paillettes du rotor.Of course, in other embodiments not shown here, it is possible to integrate, as is known in the state of the art, a transponder antenna to the start switch in order to add an electronic coding to the mechanical coding. It is also possible in this way to remove the mechanical coding of the key and thus overcome the flakes of the rotor.

Le codage ayant été reconnu, on effectue donc une rotation du rotor 2 a l'aide de la clé dans le sens des aiguilles d'une montre.Since the coding has been recognized, the rotor 2 is rotated with the key in a clockwise direction.

Comme illustré sur les figures 6a à 10a, la rotation du rotor 2 dans le sens des aiguilles d'une montre va entraîner la rotation de l'ensemble contacteur rotatif 3 dans le même sens, du fait que l'ensemble contacteur rotatif 3 est couplé directement au rotor 2 comme on l'a décrit précédemment.As illustrated on Figures 6a to 10a , the rotation of the rotor 2 in the direction of clockwise will cause rotation of the rotary switch assembly 3 in the same direction, because the rotary switch assembly 3 is coupled directly to the rotor 2 as previously described.

La rotation du rotor 2 débute dans une position angulaire (non représentée) de la clé, correspondant à un position angulaire P0 de départ du doigt 12 du coulisseau 6 dans le profil courbe de l'orifice 11 du couvercle 9. Dans l'ensemble de la description, la position angulaire du doigt 12 est calculé en référence l'axe A-A'.The rotation of the rotor 2 starts in an angular position (not shown) of the key, corresponding to a starting angular position P0 of the finger 12 of the slider 6 in the curved profile of the orifice 11 of the cover 9. In all the description, the angular position of the finger 12 is calculated with reference to the axis A-A '.

Comme on peut le constater sur la figure 5, le profil courbe de l'orifice 11 comprend plusieurs segments, un segment descendant SD le plus excentré et qui correspond à la courbe suivi par le doigt 12 lorsque la rotation de la clé s'effectue dans le sens des aiguilles d'une montre, et un segment montant SM qui correspond à la courbe suivi par le doigt 12 lorsque la rotation de la clé est dans le sens inverse des aiguilles d'une montre.As can be seen from the figure 5 , the curved profile of the orifice 11 comprises several segments, a descending segment SD the most eccentric and which corresponds to the curve followed by the finger 12 when the rotation of the key takes place in the direction of clockwise, and a rising segment SM which corresponds to the curve followed by the finger 12 when the rotation of the key is in the opposite direction of the clockwise.

Le segment descendant SD est lui même divisé en deux segments SD1 et SD2. Le premier segment SD1 suit le périmètre extérieur de l'ensemble contacteur rotatif 3 du point de départ D, jusqu'au point P. Tout au long du segment SD1, la distance au centre de l'ensemble contacteur rotatif 3 est maintenue constante à la valeur R. Le deuxième segment SD2 débute au point P pour atteindre la butée B. Le passage du point P à la butée B se produit avec une diminution de la distance au centre de l'ensemble contacteur rotatif 3. On passe d'une distance R à une distance R1, le la distance R1 étant inférieur à la distance R. Le doigt 12 se rapproche du centre de l'ensemble contacteur rotatif 3 et donc le coulisseau 6 portant le contacteur 5 se déplace radialement vers le centre de l'ensemble contacteur rotatif 3. Dans un mode de réalisation non représenté, le segment SD2 est une droite.The descending segment SD is itself divided into two segments SD1 and SD2. The first segment SD1 follows the outer perimeter of the rotary contactor assembly 3 from the starting point D, to the point P. Throughout the segment SD1, the distance at the center of the rotary contactor assembly 3 is kept constant at the value R. The second segment SD2 starts at point P to reach stop B. The transition from point P to stop B occurs with a decrease in the distance at the center of the rotary switch assembly 3. One goes from a distance R at a distance R1, the distance R1 being less than the distance R. The finger 12 approaches the center of the rotary contactor assembly 3 and thus the slider 6 carrying the contactor 5 moves radially toward the center of the assembly rotary contactor 3. In an embodiment not shown, segment SD2 is a straight line.

Quant au segment montant SM, il est également divisé en deux segments SM1 et SM2. Le premier segment SM1 débute à la butée B pour aller jusqu' à un point intermédiaire I. Tout au long de ce segment SM1, la distance au centre de l'ensemble contacteur rotatif 3 est maintenue constante à la valeur R1. Le deuxième segment SM2 débute au point I pour revenir au point de départ D. Le passage du point I au point de départ D se produit avec une augmentation de la distance au centre de l'ensemble contacteur rotatif 3. On passe d'une distance R1 à une distance R. Le doigt 12 s'éloigne donc du centre de l'ensemble contacteur rotatif 3 et donc le coulisseau 6 portant le contacteur 5 se déplace radialement en s'éloignant du centre de l'ensemble contacteur rotatif 3. Dans un mode de réalisation non représenté, le segment SM2 est une droite.As for the rising segment SM, it is also divided into two segments SM1 and SM2. The first segment SM1 starts at the stop B to go to an intermediate point I. Throughout this segment SM1, the distance to the center of the rotary contactor assembly 3 is kept constant at the value R1. The second segment SM2 starts at point I to return to starting point D. The transition from point I to point of departure D occurs with an increase in the distance to the center of the rotary contactor assembly 3. One goes from a distance R1 at a distance R. The finger 12 thus moves away from the center of the rotary switch assembly 3 and therefore the slide 6 carrying the contactor 5 moves radially away from the center of the rotary contactor assembly 3. In an embodiment not shown, the segment SM2 is a straight line.

On remarquera également qu'un indexage en position I1 et I2 est prévu sur la glissière de l'ensemble contacteur rotatif 3. Ceci permet de tenir une position fixe tant que la distance au centre de l'ensemble contacteur rotatif 3 ne change pas. Pour ce faire, et dans un mode de réalisation non limitatif illustré entre autres figures 2 et 4, le coulisseau présente des zones z1 et z2 en matériau flexible apte à s'étendre dans les encoches d'indexage A et B, et aptes à s'effacer lors du passage de l'indexation A à l'indexation B. Dans d'autre mode de réalisation on peut envisager de monter à la place des zones en matériau flexible z1 et z2 des pièces montées sur ressort, et également envisager de réaliser une ou plusieurs indexation supplémentaires.Note also that an indexing position I1 and I2 is provided on the slide of the rotary switch assembly 3. This allows to hold a fixed position as the distance to the center of the rotary switch assembly 3 does not change. To do this, and in a non-limiting embodiment illustrated among others Figures 2 and 4 , the slider has z1 and z2 areas of flexible material capable of extending into the indexing notches A and B, and able to fade during the transition from indexing A to indexing B. In Another embodiment can be considered to mount instead of the zones of flexible material z1 and z2 spring-mounted parts, and also consider making one or more additional indexing.

Le déplacement des contacteurs 4 et 5 est illustré sur les figures 6b à 14b. La correspondance de ces déplacements du point de vue de l'alimentation électrique est schématisée sur la figure 15 avec diagramme pour la sortie S1 et un autre pour la sortie S2.The displacement of the contactors 4 and 5 is illustrated on the Figures 6b to 14b . The correspondence of these displacements from the point of view of the power supply is schematized on the figure 15 with diagram for output S1 and another for output S2.

Dans la position de départ illustrée figure 6b, c'est-à-dire avec le doigt 12 en position angulaire P0 comme illustré figure 6a, aucun circuit d'alimentation n'est fermé, c'est-à-dire qu'aucune lame des contacteurs 5 ou 6 ne fait le pont entre deux pistes électriques. Ainsi aucune des voies S1, S2 ne délivre le signal +Batt.In the illustrated starting position figure 6b , that is to say with the finger 12 in angular position P0 as illustrated figure 6a no power circuit is closed, that is to say that no blade of the contactors 5 or 6 bridge between two electrical tracks. Thus none of the channels S1, S2 delivers the signal + Batt.

Comme illustré sur les figures 7a, 7b, lorsque la clé a tourné dans le sens des aiguilles d'une montre d'un angle A1 (non représenté) pour permettre au doigt 12 d'atteindre la position angulaire P1, l'ensemble contacteur rotatif 3 a également effectué une rotation dans le sens des aiguilles d'une montre d'un angle A1. Le contacteur 4 monté fixe sur l'ensemble contacteur rotatif 3 fait dans cette position le pont entre la voie +Batt et la voie S1. La sortie S1 est ainsi activée et délivre comme illustré figure 15 la tension +Batt. Cette information est interprétée par le calculateur du véhicule comme un signal de mise en marche, et le véhicule est mis en marche c'est-à-dire qu'un certain nombre d'équipement du véhicule sont mis sous tension.As illustrated on Figures 7a, 7b when the key has turned in a clockwise direction by an angle A1 (not shown) to allow the finger 12 to reach the angular position P1, the rotary switch assembly 3 has also rotated in the clockwise from an angle A1. The contactor 4 fixedly mounted on the rotary switch assembly 3 is in this position the bridge between the channel + Batt and the channel S1. The output S1 is thus activated and delivers as illustrated figure 15 the voltage + Batt. This information is interpreted by the vehicle computer as a start signal, and the vehicle is turned on, that is, a certain number of vehicle equipment is turned on.

Cette position correspond également, dans un dispositif haut de gamme de démarrage muni d'un lecteur de badge et d'un bouton poussoir, à la présence d'un badge conforme introduit dans le lecteur de badge.This position also corresponds, in a high-end startup device provided with a badge reader and a push button, the presence of a conforming badge introduced in the badge reader.

Du point de vue du contacteur 5 monté sur le coulisseau 6, le doigt 12 à la position angulaire P1, s'est déplacé sur le segment SD1 à une distance au centre de l'ensemble contacteur rotatif 3 constante R. Donc le coulisseau n'a pas bougé radialement et donc à ce stade la sortie S2 est toujours inactivée.From the point of view of the contactor 5 mounted on the slider 6, the finger 12 at the angular position P1 has moved on the segment SD1 at a distance from the center of the rotary contactor assembly 3 constant R. Thus the slider n ' has not moved radially and so at this stage the output S2 is still inactivated.

Comme illustré sur les figures 8a, 8b, en tournant plus avant la clé dans le sens des aiguilles d'une montre d'un angle A2 (non représenté), pour permettre au doigt 12 d'atteindre la position angulaire P2, l'ensemble contacteur rotatif 3 a également effectué une rotation dans le sens des aiguilles d'une montre d'un angle A2. Le contacteur 4 monté fixe sur l'ensemble contacteur rotatif 3 fait dans cette position toujours le pont entre la voie +Batt et la voie S1. La sortie S1 est donc toujours activée.As illustrated on Figures 8a, 8b , by further turning the key clockwise an angle A2 (not shown), to allow the finger 12 to reach the angular position P2, the rotary switch assembly 3 has also rotated clockwise from an angle A2. The contactor 4 fixedly mounted on the rotary switch assembly 3 is in this position always the bridge between the channel + Batt and the channel S1. Output S1 is always activated.

Du point de vue du contacteur 5 monté sur le coulisseau 6, le doigt 12 en position angulaire P2 est passé dans le segment SD2 avec une diminution de la distance au centre de l'ensemble contacteur rotatif 3. Le doigt 12 s'est rapproché du centre de l'ensemble contacteur rotatif 3 entraînant un déplacement radial du coulisseau vers le centre de l'ensemble contacteur rotatif 3. Dans cette position la lame du contacteur 5 vient établir un pont entre la voie +Batt et la voie S2. La sortie S2 est ainsi activé, et délivre comme illustré figure 15 la tension +Batt. Cette information est interprétée par le calculateur du véhicule comme un signal de démarrage du moteur, et le moteur du véhicule est démarré.From the point of view of the contactor 5 mounted on the slider 6, the finger 12 in the angular position P2 is passed in the segment SD2 with a decrease in the distance at the center of the rotary contactor assembly 3. The finger 12 has approached the center of the rotary contactor assembly 3 causing a radial displacement of the slide towards the center of the rotary switch assembly 3. In this position the contactor blade 5 comes to establish a bridge between the + Batt channel and the S2 channel. The output S2 is thus activated, and delivers as illustrated figure 15 the voltage + Batt. This information is interpreted by the vehicle computer as a start signal of the engine, and the vehicle engine is started.

Du point de vue des dispositif à lecteur de badge + bouton poussoir, cette position équivaut à l'appui sur le bouton poussoir pour démarrer le moteur.From the point of view of the device with badge reader + push button, this position is equivalent to pressing the push button to start the engine.

Comme illustré sur les figures 9a, 9b, en tournant encore plus avant la clé dans le sens des aiguilles d'une montre d'un angle A3 (non représenté), pour permettre au doigt 12 d'atteindre la position angulaire P3, l'ensemble contacteur rotatif 3 a également effectué une rotation dans le sens des aiguilles d'une montre d'un angle A3. Le contacteur 4 monté fixe sur l'ensemble contacteur rotatif 3 fait encore dans cette position le pont entre la voie +Batt et la voie S1. La sortie S1 est donc encore activée.As illustrated on Figures 9a, 9b by further turning the key clockwise an angle A3 (not shown), to allow the finger 12 to reach the angular position P3, the rotary switch assembly 3 also performed a clockwise rotation of an angle A3. The contactor 4 fixedly mounted on the rotary switch assembly 3 is still in this position the bridge between the channel + Batt and the channel S1. Output S1 is therefore still activated.

Du point de vue du contacteur 5 monté sur le coulisseau 6, le doigt 12 en position P3 s'est déplacé plus loin sur le segment SD2, entraînant un déplacement radial supplémentaire du coulisseau vers le centre de l'ensemble contacteur rotatif 3. Dans cette position la lame du contacteur 5 n'établit plus le pont entre la voie +Batt et la voie S2. La sortie S2 est ainsi désactivée et comme illustré figure 15 ne délivre plus de tension au niveau de la sortie S2.From the point of view of the switch 5 mounted on the slider 6, the finger 12 in the P3 position has moved further on the SD2 segment, causing an additional radial displacement of the slider towards the center of the rotary switch assembly 3. In this position the contactor blade 5 no longer establishes the bridge between the track + Batt and the track S2. The output S2 is thus deactivated and as illustrated figure 15 no longer delivers voltage at output S2.

Du point de vue des dispositif à lecteur de badge + bouton poussoir, cette position équivaut au relâchement du bouton poussoir, le moteur étant toujours en marche.From the point of view of the device with badge reader + push button, this position is equivalent to the release of the push button, the motor being always running.

A ce stade, le calculateur du véhicule, monté en aval de la sortie S2, a donc interprété, sans avoir recours à des modification notables par rapport au cas du lecteur de badge + bouton poussoir, l'activation puis la désactivation de la sortie S2, comme une impulsion de commande de démarrage du moteur.At this stage, the vehicle computer, mounted downstream of the output S2, has interpreted, without resorting to significant changes compared to the case of the badge reader + push button, the activation and deactivation of the output S2 , as a motor start control pulse.

Enfin, comme illustré sur les figures 10a, 10b, en tournant encore plus avant la clé dans le sens des aiguilles d'une montre d'un angle A4 (non représenté), pour permettre au doigt 12 d'atteindre la position angulaire P4, l'ensemble contacteur rotatif 3 a également effectué une rotation dans le sens des aiguilles d'une montre d'un angle A4. Le contacteur 4 monté fixe sur l'ensemble contacteur rotatif 3 fait encore dans cette position le pont entre la voie +Batt et la voie S1. La sortie S1 est donc toujours activée.Finally, as illustrated on Figures 10a, 10b by further turning the key clockwise an angle A4 (not shown), to allow the finger 12 to reach the angular position P4, the rotary switch assembly 3 also performed a clockwise rotation of an angle A4. The contactor 4 fixedly mounted on the rotary switch assembly 3 is still in this position the bridge between the channel + Batt and the channel S1. Output S1 is always activated.

Du point de vue du contacteur 5 monté sur le coulisseau 6, le doigt 12 en position P4, s'est déplacé plus loin sur le segment SD2, pour atteindre la butée entraînant un déplacement radial supplémentaire du coulisseau vers le centre de l'ensemble contacteur rotatif 3. Dans cette position la lame du contacteur 5 n'établit pas de pont entre la voie +Batt et la voie S2. La sortie S2 est toujours désactivée.From the point of view of the switch 5 mounted on the slider 6, the finger 12 in the P4 position, has moved further on the SD2 segment, to reach the stop causing an additional radial displacement of the slider towards the center of the contactor assembly 3. In this position the contactor blade 5 does not establish a bridge between the + Batt channel and the S2 channel. Output S2 is always off.

Du point de vue des dispositif à lecteur de badge + bouton poussoir, cette position équivaut au bouton poussoir en position relâchée.From the point of view of the device with badge reader + push button, this position is equivalent to the push button in the released position.

La rotation de la clé dans le sens des aiguilles d'une montre d'un angle A4 (non représenté), pour permettre au doigt 12 d'atteindre la position angulaire P4 en butée, s'est faite à l'encontre du ressort de rappel 13.The rotation of the key in a clockwise direction by an angle A4 (not shown), to allow the finger 12 to reach the angular position P4 in abutment, was made against the spring of reminder 13.

Comme illustré figures 11a et 11b, en relâchant la clé, le ressort de rappel 13 ramène automatiquement, par rotation dans le sens inverse des aiguilles d'une montre d'un angle A5, et permet au doigt 12 d'atteindre la position angulaire P5.As illustrated Figures 11a and 11b releasing the key, the return spring 13 automatically returns, by rotation in the counterclockwise direction of an angle A5, and allows the finger 12 to reach the angular position P5.

Le contacteur 4 monté fixe sur l'ensemble contacteur rotatif 3 fait encore dans cette position le pont entre la voie +Batt et la voie S1. La sortie S1 est donc encore activée.The contactor 4 fixedly mounted on the rotary switch assembly 3 is still in this position the bridge between the channel + Batt and the channel S1. Output S1 is therefore still activated.

Du point de vue du contacteur 5 monté sur le coulisseau 6, le doigt 12 en position P5, s'est déplacé à présent sur le segment montant SM, et plus spécifiquement ici sur le segment SM1, à une distance au centre de l'ensemble contacteur rotatif 3 R1 constante. Le coulisseau 6 demeure donc dans sa position la plus enfoncé vers le centre de l'ensemble contacteur rotatif 3 car la distance au centre de l'ensemble contacteur rotatif 3 R1 n'a pas changé. Dans cette position la lame du contacteur 5 n'établit pas de pont entre la voie +Batt et la voie S2. La sortie S2 reste désactivée.From the point of view of the contactor 5 mounted on the slider 6, the finger 12 in position P5, has now moved on the rising segment SM, and more specifically here on the segment SM1, at a distance to the center of the assembly rotary switch 3 R1 constant. The slider 6 thus remains in its most recessed position toward the center of the rotary contactor assembly 3 because the distance to the center of the rotary contactor assembly 3 R1 has not changed. In this position the contactor blade 5 does not establish a bridge between the + Batt channel and the S2 channel. Output S2 remains disabled.

A ce stade, l'utilisateur n'a pas ressenti de différence de comportement de l'interrupteur de démarrage par rapport à un interrupteur à rotor de type classique.At this stage, the user did not feel any difference in the behavior of the start switch with respect to a conventional type rotor switch.

Afin d'extraire la clé du rotor 2 il est nécessaire de poursuivre la rotation dans le sens inverse des aiguilles d'une montre jusqu'à la position angulaire A0 de départ. Dans l'exemple de réalisation illustré figure 12a, 12b à 14a, 14b et schématisé du point de vue de l'alimentation électrique par la figure 10.In order to extract the key from the rotor 2 it is necessary to continue the rotation in the counterclockwise direction to the starting angular position A0. In the illustrated example figure 12a , 12b to 14a , 14b and schematized from the point of view of the power supply by the figure 10 .

Comme illustré sur la figure 12a et 12b, lorsque la clé atteint la position angulaire A6, cela se traduit en ce que le doigt 12 du coulisseau 6 passe par une position P6. Cela se traduit au niveaux du contacteur 4 par le fait que lame du contacteur 4 passe par une position où elle n'établit plus de pont entre la voie +Batt et la voie S1, ce qui entraîne une désactivation de la voie S1.As illustrated on the figure 12a and 12b when the key reaches the angular position A6, this means that the finger 12 of the slider 6 passes through a position P6. This is reflected at the level of the contactor 4 by the fact that the contactor blade 4 passes through a position where it no longer establishes a bridge between the channel + Batt and the channel S1, which causes a deactivation of the channel S1.

Cette mise en état de désactivation de la sortie S1 en tant que première étape significative du retrait de la clé, simule l'extraction d'un badge avant l'arrêt du moteur, processus possible dans certains véhicules. Dans une alternative, la sortie S1 reste activée à ce stade et notamment jusqu'à la coupure moteur, c'est dire deuxième activation de la sortie S2, ou bien même postérieurement à cette étape.This deactivation of the S1 output as the first significant step in the removal of the key simulates the extraction of a badge before stopping the engine, a process that is possible in some vehicles. In an alternative, the output S1 remains activated at this stage and in particular until the engine shutdown, ie second activation of the output S2, or even after this step.

A ce stade, et dans le même temps, le doigt 12 du coulisseau 6 a atteint la position P6, illustré figure 12a, 12b, en empruntant le segment SM2 avec une distance au centre de l'ensemble contacteur rotatif 3 augmentant passant de R1 à R. Le coulisseau 6 a commencé ainsi son éloignement du centre de l'ensemble contacteur rotatif 3, mais la lame du contacteur 5 n'établit pas encore de pont entre la voie +Batt et la voie S2. La sortie S2 reste désactivée.At this point, and at the same time, the finger 12 of the slider 6 has reached the position P6, illustrated figure 12a, 12b , taking the segment SM2 with a distance at the center of the increasing rotary switch assembly 3 from R1 to R. The slider 6 has thus begun to move away from the center of the rotary switch assembly 3, but the contactor blade 5 does not yet build a bridge between the + Batt channel and the S2 channel. Output S2 remains disabled.

Comme illustré sur la figure 13a et 13b, lorsque la clé atteint la position angulaire A7, cela se traduit en ce que le doigt 12 du coulisseau 6 passe par une position P7. Cela se traduit au niveau du contacteur 4 par le fait que lame du contacteur 4 est toujours dans une position où elle n'établit plus de pont entre la voie +Batt et la voie S1. La voie S1 est toujours désactivée.As illustrated on the Figure 13a and 13b when the key reaches the angular position A7, this means that the finger 12 of the slider 6 passes through a position P7. This is reflected in the switch 4 by the fact that the contactor blade 4 is always in a position where it no longer establishes a bridge between the + Batt channel and the S1 channel. Channel S1 is always off.

Dans le même temps, le doigt 12 du coulisseau 6 a atteint la position P7, en empruntant le segment SM2 avec une distance au centre de l'ensemble contacteur rotatif 3 augmentant passant de R1 à R. Le coulisseau 6 a continué son éloignement du centre de l'ensemble contacteur rotatif 3, et la lame du contacteur 5 vient maintenant établir un pont entre la voie +Batt et la voie S2. La sortie S2 est a présent activée et délivre comme illustré figure 15 la tension +Batt. Cette information est interprétée par le calculateur du véhicule comme un signal de coupure moteur, et le moteur du véhicule est coupé.At the same time, the finger 12 of the slider 6 has reached the position P7, by taking the segment SM2 with a distance at the center of the rotating contactor assembly 3 increasing from R1 to R. The slider 6 has continued its distance from the center of the rotary contactor assembly 3, and the contactor blade 5 now comes to bridge the channel + Batt and the path S2. Output S2 is now enabled and delivered as shown figure 15 the voltage + Batt. This information is interpreted by the vehicle computer as an engine shutdown signal, and the vehicle engine is shut down.

Enfin, comme illustré sur la figure 14a et 14b, lorsque la clé revient à la position de départ A0, cela se traduit en ce que le doigt 12 du coulisseau 6 retourne à la position de départ P0. Cela se traduit au niveau du contacteur 4 par le fait que lame du contacteur 4 est toujours dans une position où elle n'établit plus de pont entre la voie +Batt et la voie S1. La voie S1 est toujours désactivée.Finally, as illustrated on the Figure 14a and 14b when the key returns to the starting position A0, this results in the finger 12 of the slider 6 returning to the starting position P0. This is reflected in the switch 4 by the fact that the contactor blade 4 is always in a position where it no longer establishes a bridge between the + Batt channel and the S1 channel. Channel S1 is always off.

Dans le même temps, le doigt 12 du coulisseau 6 a atteint la position P0, en empruntant le segment SM2 avec une distance au centre de l'ensemble contacteur rotatif 3 augmentant passant de R1 à R. Le coulisseau 6 a continué son éloignement du centre de l'ensemble contacteur rotatif 3, et la lame du contacteur 5 n'établit plus le pont entre la voie +Batt et la voie S2. La sortie S2 est a présent désactivée.At the same time, the finger 12 of the slider 6 has reached the position P0, by taking the segment SM2 with a distance at the center of the rotating contactor assembly 3 increasing from R1 to R. The slider 6 has continued its distance from the center of the rotary contactor assembly 3, and the contactor blade 5 no longer establishes the bridge between the + Batt channel and the S2 channel. Output S2 is now disabled.

Du point de vue des dispositif à lecteur de badge + bouton poussoir, cette position équivaut au relâchement après le deuxième appui sur le bouton poussoir pour couper le moteur.From the point of view of the device with badge reader + push button, this position is equivalent to the release after the second pressing of the push button to shut down the engine.

Le calculateur du véhicule a donc reçu un signal équivalent à une impulsion de commande d'arrêt du moteur comme c'est le cas avec un bouton poussoir classique, n'entraînant ainsi aucune modification notable du calculateur.The vehicle computer has therefore received a signal equivalent to an engine stop control pulse as is the case with a conventional push button, thus causing no significant modification of the computer.

L'invention ne se limite pas au mode de réalisation qui vient d'être décrit. Comme on l'a déjà indiqué les pistes peuvent êtres replacé par des micro-interrupteurs. D'autre part il est possible d'envisager le déplacement du coulisseau autre que radial, par exemple transversal. Le dispositif peut également être muni de plusieurs contacteurs fixés mobiles sur l'ensemble contacteur rotatif.The invention is not limited to the embodiment which has just been described. As already indicated, the tracks can be replaced by microswitches. On the other hand it is possible to consider the displacement of the slider other than radial, for example transverse. The device may also be provided with a plurality of fixed contactors movable on the rotary switch assembly.

Comme schématisé sur la figure 16, l'interrupteur de démarrage, selon le mode de réalisation de l'invention qui vient d'être décrit et qui est non limitatif, est tout à fait adapté pour permettre de la manière la plus simple et économique possible, le passage d'un véhicule dans une version dite « haut de gamme », avec entre autres un badge, un lecteur de badge, un bouton poussoir, un calculateur, un démarreur et un antivol de direction électrique, au même véhicule dans sa version dit « bas de gamme » avec une clé, un interrupteur de démarrage, un calculateur, un démarreur et un antivol de direction électrique.As schematized on the figure 16 , the start switch, according to the embodiment of the invention which has just been described and which is non-limiting, is entirely adapted to allow in the most simple and economical way possible, the passage of a vehicle in a so-called "high-end" version, including a badge, a badge reader, a push button, a computer, a starter and an electric steering lock, to the same vehicle in its so-called "low-end" version with a key, a start switch, a computer, a starter and an electric steering lock.

Le passage de la version dite « haut de gamme » à la version dite « bas de gamme » se fait en introduisant dans le logement du bouton poussoir un interrupteur de démarrage selon l'invention. L'entrée du lecteur de badge peut être est condamnée, et le reste de l'architecture mécanique et électrique du véhicule peut être conservée.The passage of the so-called "high-end" version to the so-called "low-end" version is done by introducing into the housing of the push button a start switch according to the invention. The entry of the badge reader can be condemned, and the rest of the mechanical and electrical architecture of the vehicle can be retained.

Dans un autre mode de réalisation simplifié, non représenté, d'un interrupteur de démarrage selon l'invention, on ne dispose plus que d'une sortie électrique activée par un unique contacteur monté mobile sur l'ensemble contacteur rotatif. Dans cette configuration l'activation puis la désactivation de la sortie unique, lors de la rotation du rotor dans un premier sens, sera interprétée par le calculateur comme la mise en marche du véhicule et le démarrage du moteur, et l'activation puis la désactivation de la sortie unique lors de la rotation du rotor dans le sens inverse, sera interprétée par le calculateur comme la coupure du moteur et de l'alimentation du véhicule.In another simplified embodiment, not shown, of a starting switch according to the invention, there is only one electrical output activated by a single switch mounted on the rotary switch assembly. In this configuration the activation and deactivation of the single output, during the rotation of the rotor in a first direction, will be interpreted by the computer as the start of the vehicle and the start of the engine, and the activation and deactivation of the single output when rotating the rotor in the opposite direction, will be interpreted by the computer as the shutdown of the engine and the vehicle power supply.
