Description

INTERRUPTEUR SECURISE A FAIBLE COURANT ET A FIABILITE AUGMENTEESECURE SWITCH WITH LOW CURRENT AND INCREASED RELIABILITY
DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION
L'invention concerne un interrupteur électrique à fiabilité augmentée.The invention relates to an electrical switch with increased reliability.
Elle concerne plus particulièrement mais non exclusivement pour ce qui concerne les commutations électriques ayant un aspect sécuritaire, en particulier pour la mise en marche et l'arrêt d'au moins une unité d'opération d'un véhicule automobile pour lequel il est important que le niveau de sécurité soit nettement amélioré.It relates more particularly, but not exclusively, to electrical switches having a safety aspect, in particular for starting and stopping at least one operating unit of a motor vehicle for which it is important that the level of security is significantly improved.
Elle s'applique d'une façon particulièrement avantageuse dans le cas d'un interrupteur à faible courant intégré à un antivol de véhicule.It applies particularly advantageously in the case of a low-current switch integrated into a vehicle lock.
ETAT DE LA TECHNIQUESTATE OF THE ART
Sur un antivol de direction par exemple, la commutation électrique présente un aspect sécuritaire. En effet un défaut de commutation peut avoir des conséquences dramatiques pour l'utilisateur du véhicule (incendie, accident...). Ce problème est d'autant plus important que la coupure du moteur n'est gérée que par l'antivol (retour en position "stop" de l'antivol qui entraîne l'arrêt de toute alimentation, hormis l'alimentation à l'interrupteur lui même).On a steering lock for example, the electrical switching has a safe appearance. Indeed a fault of switching can have dramatic consequences for the user of the vehicle (fire, accident ...). This problem is all the more important as the shutdown of the engine is managed only by the antitheft device (return to the "stop" position of the antitheft device which stops all power supply, except for the power supply to the switch himself).
D'une façon générale, les verrous d'antivol d'automobile peuvent utiliser des interrupteurs à lame souple sensible aux champs magnétiques. Ces interrupteurs sont usuellement désignés par "interrupteurs ILS" ou "ampoules REED" ou "LL. S.". Ces interrupteurs coopèrent avec des aimants permanents solidaires du rotor du verrou de manière à être sensibles à la position après entraînement en rotation du rotor par la clef de contact.In general, automotive anti-theft locks can use soft-blade switches sensitive to magnetic fields. These switches are usually referred to as "ILS switches" or "REED bulbs" or "LL.S". These switches cooperate with permanent magnets secured to the rotor of the lock so as to be responsive to the position after rotation of the rotor by the ignition key.
Or il s'avère que ces interrupteurs ont le désavantage d'avoir comme mode de défaillance « préférentiel » un collage permanant des lames car leurs éléments de contacts ont tendance à se coller en position fermée, un arc électrique pouvant se former lors de la fermeture du contact.However, it turns out that these switches have the disadvantage of having as mode of failure "preferential" a permanent gluing of the blades because their contact elements tend to stick in the closed position, an electric arc can be formed during closing contact.
Il est très difficile d'améliorer cette fiabilité sans augmenter de façon très importante le prix, et/ou le volume occupé. Or les critères de prix et d'espace nécessaire sont très importants dans les domaines actuels de l'industrie comme l'automobile ou l'aéronautique par exemple.It is very difficult to improve this reliability without significantly increasing the price and / or the volume occupied. But the criteria of price and space required are very important in the current areas of industry such as automotive or aeronautics, for example.
Sur un véhicule à architecture "faible courant" l'interrupteur ne donne qu'une information sur la position de la clef, il n'établit pas physiquement les différents contacts. Cette nouvelle façon de gérer l'information, associée à des problèmes liés au mode de fabrication des interrupteurs peut être à l'origine de contacts non désirés. Par exemple un véhicule peut démarrer sans que la clef soit présente dans l'antivol et sans que celui-ci soit commuté en position démarrage.On a vehicle with architecture "weak current" the switch gives only information on the position of the key, it does not physically establish the various contacts. This new way of managing information, associated with problems related to the mode of manufacture of the switches can be at the origin of unwanted contacts. For example a vehicle can start without the key is present in the lock and without it being switched to the start position.
Jusqu'à aujourd'hui, les interrupteurs de démarrage comprennent une alimentation électrique et deux contacts placés en parallèle. En effet placer les deux interrupteurs en série diminue en général la fiabilité globale de l'ensemble. Dans un montage en série la probabilité pour avoir un non démarrage est plus grande que si les deux interrupteurs sont montés en parallèle. Par exemple si la probabilité d'avoir une panne d'un interrupteur est égale à 1/1000e la probabilité d'avoir un non démarrage (pour un montage en série) est égale à 2/1000 alors que la probabilité d'avoir un non démarrage (pour un montage en parallèle est égale à 1/1000. C'est pour cette raison que les deux interrupteurs étaient jusqu'à aujourd'hui montés en parallèle. Dans ce montage le premier interrupteur est un interrupteur général et le deuxième interrupteur est un interrupteur de démarrage. Le premier interrupteur en position fermée permet l'alimentation générale du véhicule (position marche) hormis l'alimentation du démarreur. Le deuxième interrupteur en position fermée permet quant à lui l'alimentation du démarreur.Until today, the start switches include a power supply and two contacts placed in parallel. Indeed, placing the two switches in series generally decreases the overall reliability of the assembly. In a series circuit, the probability of having no start is greater than if both switches are connected in parallel. For example if the probability of having a switch failure is equal to 1/1000 th the probability of having a non-start (for a series connection) is equal to 2/1000 while the probability of having a non-start is no start (for a parallel connection is equal to 1/1000.) This is why the two switches were until now mounted in parallel. In this assembly the first switch is a main switch and the second switch is a start switch. The first switch in the closed position allows the general power supply of the vehicle (on position) except the power supply of the starter. The second switch in the closed position allows the power supply of the starter.
Lorsqu'on réalise une matrice de fonctionnement prenant en compte les configurations possibles et les possibilités de panne et que l'on prend en considération le fait que l'occurrence d'une panne en position fermée est plus probable que l'occurrence d'une panne en position ouverte, on s'aperçoit que l'une des dites configuration est non désirée d'un point de vue fonctionnel et même que cette situation peut avoir des conséquences graves sur la sécurité en actionnant le démarreur de façon intempestive. Pour simplifier la présentation on appellera : le premier interrupteur : Kl le deuxième interrupteur : K2 la commande mécanique du premier interrupteur : Sl (Sl = 1 entraîne la présence d'un signal sur la sortie marche). - la commande mécanique du deuxième interrupteur : S2 (S2 = 1 entraîne la présence d'un signal sur la sortie DEM). l'alimentation de la batterie : +BAT = 0 circuit ouvert (pour Kl ou K2) = 1 circuit fermé (pour Kl et K2) - = 0 absence de signal sur les sorties Sl et S2When performing an operating matrix taking into account the possible configurations and the possibilities of failure and taking into account the fact that the occurrence of a failure in the closed position is more likely than the occurrence of a failure. failure in the open position, one realizes that one of said configuration is unwanted from a functional point of view and even that this situation can have serious consequences on safety by operating the starter inadvertently. To simplify the presentation we will call: the first switch: Kl the second switch: K2 the mechanical control of the first switch: Sl (Sl = 1 causes the presence of a signal on the output on). - The mechanical control of the second switch: S2 (S2 = 1 causes the presence of a signal on the DEM output). the battery supply: + BAT = 0 open circuit (for K1 or K2) = 1 closed circuit (for K1 and K2) - = 0 no signal on the outputs S1 and S2
= 1 signal sur les sorties Sl et S2= 1 signal on the outputs Sl and S2
Les quatre cas suivants sont alors possibles :The following four cases are then possible:
1) Kl=O, K2=0, Sl=O, et S2=0: ceci correspond à une position stop (normale) 2) Kl=O, K2=l, Sl=O, et S2= 0: ceci correspond à une panne car le démarreur est activé suite à une panne de l'interrupteur en position fermée (panne grave)1) K1 = O, K2 = 0, Sl = 0, and S2 = 0: this corresponds to a stop position (normal) 2) Kl = O, K2 = 1, Sl = 0, and S2 = 0: this corresponds to a fault because the starter is activated following a failure of the switch in the closed position (serious breakdown)
3) Kl=I, K2=0, Sl=I, et S2= 0: ceci correspond à la position marche (normale)3) Kl = I, K2 = 0, Sl = I, and S2 = 0: this corresponds to the on (normal) position
4) Kl=I, K2=l, Sl=I, et S2= 1: ceci correspond à une position marche du démarreur (normale)4) Kl = I, K2 = 1, Sl = I, and S2 = 1: this corresponds to a start position of the starter (normal)
Les quatre cas se trouvent illustrés sur le tableau suivant:The four cases are illustrated in the following table:
Tableau 1Table 1
Figure imgf000005_0001
Figure imgf000005_0001
Lorsque l'on étudie avec soin le tableau précédent représentant les cas de panne possible et lorsque l'on considère que dans ce cas précis la probabilité d'occurrence d'une panne en position fermée est beaucoup plus grande qu'une pane en position ouverte pour chaque interrupteur pris séparément et que l'on considère les incidences de ces pannes sur la sécurité on s'aperçoit que la solution actuelle ne permet pas d'avoir une sécurité suffisante.When one carefully studies the preceding table representing possible failure cases and when one considers that in this case the probability of occurrence of a failure in the closed position is much greater than In the open position for each switch taken separately and that we consider the impact of these failures on security we realize that the current solution does not allow to have sufficient security.

BREVE DESCRIPTION DES FIGURESBRIEF DESCRIPTION OF THE FIGURES
Un mode de réalisation de l'invention sera décrit ci-après à titre d'exemple non limitatif, en faisant référence au dessin annexé dans lequel,One embodiment of the invention will be described hereinafter by way of non-limiting example, with reference to the appended drawing in which,
La figure 1 montre schématiquement une disposition préférée selon l'invention.Figure 1 shows schematically a preferred arrangement according to the invention.
DESCRIPTION DETAILLEE DE MODES DE REALISATION NON LIMITATIFS DE L'INVENTIONDETAILED DESCRIPTION OF NON-LIMITING EMBODIMENTS OF THE INVENTION
Dans l'exemple illustré dans La figure 1 une alimentation batterie appelée +BAT est reliée à une borne KlA d'un premier contact appelé Kl. Ce contact est ici une ampoule REED qui comprend un ensemble de bilames qui sont séparées en position repos et qui se ferment lorsque qu'une masselotte magnétique est placée près d'elles. L'autre borne KlB du premier contact est connectée d'une part à l'alimentation (MARCHE Sl) des équipements du véhicule et d'autre part à la première borne K2A d'un deuxième contact K2. Le contact K2 est ici également une ampoule REED. La deuxième borne K2B du deuxième contact K2 est reliée au démarreur (DEM S2) Lorsque l'on étudie la matrice des possibilités également appelée table de vérité ou tableau de "Karnaught", on voit qu'il est impossible de générer un démarrage intempestif dans le cas d'une défaillance d'un interrupteur Kl ou K2.In the example illustrated in FIG. 1, a battery supply called + BAT is connected to a terminal K1A of a first contact called K1. This contact is here a REED bulb which comprises a set of bimetallic strips which are separated in the rest position and which close when a magnetic counterweight is placed near them. The other terminal KlB of the first contact is connected on the one hand to the power supply (ON Sl) of the vehicle equipment and on the other hand to the first terminal K2A of a second contact K2. Contact K2 is here also a bulb REED. The second terminal K2B of the second contact K2 is connected to the starter (DEM S2) When studying the matrix of possibilities also called truth table or table of "Karnaught", it is seen that it is impossible to generate a nuisance start in the case of a failure of a switch K1 or K2.
En reprenant la terminologie définie plus haut la matrice s'énonce de la façon suivante :Using the terminology defined above, the matrix is expressed as follows:
1) Kl=O, K2=0, Sl=O5 et S2=0: ceci correspond à une position stop (normale)1) Kl = O, K2 = 0, Sl = O 5 and S2 = 0: this corresponds to a stop position (normal)
2) Kl=O, K2=l, Sl=O, et S2= 0: pas de démarrage2) K1 = O, K2 = 1, Sl = 0, and S2 = 0: no start
3) Kl=I, K2=0, Sl=I, et S2= 0: ceci correspond à la position marche (normale) 4) Kl=I, K2=l, Sl=I, et S2= 1: ceci correspond à une position marche du démarreur (normale)3) K1 = I, K2 = 0, Sl = I, and S2 = 0: this corresponds to the on (normal) position 4) K1 = I, K2 = 1, Sl = I, and S2 = 1: this corresponds to a starting position of the starter (normal)
On voit bien que dans ce cas la sécurité est nettement améliorée car il est impossible d'avoir un démarrage intempestif du démarreur avec une simple panne d'un des deux interrupteurs même bloqués en position fermée.It is clear that in this case the safety is significantly improved because it is impossible to have an inadvertent start of the starter with a simple failure of one of the two switches even blocked in the closed position.
Le dispositif selon l'invention convient bien pour améliorer la sécurité du système contre les démarrages intempestifs. Ce dispositif peut être généralisé à tous les systèmes qui doivent commander de façon sure des fonctionnalités particulière de machines. Ce dispositif, suivant l'invention, n'est donc pas limité aux exemples énoncés plus haut, mais peut être modifié dans le cadre des revendications sans changer la portée de celui-ci. The device according to the invention is well suited for improving the safety of the system against inadvertent starts. This device can be generalized to all systems that must securely control particular machine features. This device according to the invention is therefore not limited to the examples stated above, but can be modified within the scope of the claims without changing the scope thereof.
