Abstract

Typically, a steering column (4) is immobilised by a bolt (15) driven into a recess by a reversible motor (10). The motor is controlled by two change-over relays (13,13'), switched by transistors (12,12') selectively operated by an elecronic controller (11). Each relay's moving contact, connected to one motor pole, normally completes an earth connection. Depending on the rotation required, one relay is energised to break this connection and connect its motor pole to the supply (Vbat, 17), the other pole remaining earthed. The controller is powered up by a third transistor (14) only when the access control unit (2) accepts the driver's authorisation; the same unit unlocks the doors, permits start-up and, via the controller (11), withdraws the column locking bolt. A blocking relay (5) also energised, prepares the circuit of a change-over relay (3) which is then closed by the bolt's end-of-travel switch (16). This relay deenergises the motor circuit (17) and makes supply available to essential engine auxiliaries (+APC). Following this sequence, neither an electrical control fault nor spurious attempts to lock the steering can degrade safety in normal operation. Equally, the engine cannot be started with the lock bolt incompletely withdrawn. After the driver leaves the fully locked state is regained.

Description

La presente invention est relative<B>à</B> un dispositif de verrouillage d'un arbre de transmission 'un véhicule automobile, tel qu'une colonne de direction ou un arbre de boite de vitesse, et plus particulièrement<B>à</B> un tel dispositif utilisant un moteur électrique pour effectuer le verrouillage, dont la sécurité de fonctionnement est renforcée. Les véhicules modernes comportent de plus en plus des systèmes de contrôle d'accès dits "mains libres", avec lesquels il n'est plus necessaire de se servir d'une clé mécanique, tant pour accéder<B>à</B> l'intérieur du véhicule pour démarrer le moteur. Avec la disparition de la clé<B>de</B> contact, il a été nécessaire de remplacer les verrous mécaniques de blocage de la colonne de direction par verrous actionnés électriquement. Ces verrous électriques doivent offrir la même sécurité de fonctionnement que les dispositifs mécaniques qu'ils remplacent, 'est<B>à</B> dire garantir que le moteur du véhicule ne peut être ni lancé, ni en fonctionnement si la colonne de direction n'est pas déverrouillée. De même, le verrouillage de la colonne de direction doit être impossible tant que le véhicule n'est pas<B>à</B> l'arrêt complet, moteur éteint. The present invention is relative to a locking device of a transmission shaft of a motor vehicle, such as a steering column or a gearbox shaft, and more particularly to a gearbox shaft. </ B> such a device using an electric motor to perform the locking, whose operational safety is enhanced. Modern vehicles increasingly include so-called "hands-free" access control systems, with which it is no longer necessary to use a mechanical key, both to access <b> to </ b> l inside the vehicle to start the engine. With the disappearance of the key <B> of </ B> contact, it was necessary to replace the mechanical locking locks of the steering column by electrically operated locks. These electric locks must offer the same operational safety as the mechanical devices they replace, 'is <B> to </ B> to guarantee that the engine of the vehicle can not be launched or in operation if the steering column is not unlocked. Likewise, the steering column lock must be impossible until the vehicle is at full stop with the engine off.

<B>Il</B> a été par ailleurs proposé, en vue de la même fonction d'antivol, de verrouiller d'autres organes essentiels, tels qu'un arbre de boite de vitesse, avec le même type de verrou électrique, qui doivent eux aussi répondre aux mêmes impératifs de sécurité. On se limitera donc par la suite<B>à</B> une description relative<B>à</B> la colonne de direction, étant entendu que les moyens décrits peuvent s'appliquer, mutatis mutandis, <B>à</B> un quelconque arbre de transmission. <B> It </ B> has also been proposed, for the same anti-theft function, to lock other essential organs, such as a gearbox shaft, with the same type of electric lock, who must also meet the same security requirements. We will limit thereafter <B> to </ B> a relative description <B> to </ B> the steering column, it being understood that the means described may apply, mutatis mutandis, <B> to < / B> any drive shaft.

On connaît de la technique antérieure, par exemple du brevet<B>US</B> <B>4,638,882,</B> un tel dispositif de verrouillage électrique de la colonne de direction, dans lequel les impératifs de sécurité précités sont assurés par une électronique complexe. Une défaillance de celle-ci, d'autant plus probable qu'elle est complexe, peut entraîner un problème de sécurité de fonctionnement, susceptible de mettre en danger les utilisateurs du véhicule, par exemple en cas de verrouillage de la colonne de direction pendant la marche du véhicule. It is known from the prior art, for example from US Pat. No. 4,638,882, such a device for electrically locking the steering column, in which the aforementioned security requirements are provided by complex electronics. A failure thereof, all the more likely that it is complex, can cause a problem of operational safety, may endanger the users of the vehicle, for example in the case of locking the steering column during the vehicle running.

La présente invention a donc pour but de proposer un dispositif de verrouillage de la colonne de direction d'un véhicule automobile, ou d'un quelconque arbre de transmission dudit véhicule, dont la sécurité de fonctionnement est renforcée. The present invention therefore aims to provide a locking device of the steering column of a motor vehicle, or any transmission shaft of said vehicle, whose operational safety is enhanced.

On atteint ces buts de l'invention, ainsi que d'autres qui apparaîtront dans la suite de la présente description, au moyen d'un dispositif de verrouillage d'un arbre de transmission d'un véhicule automobile, du type utilisant un verrou électrique comprenant un pene mu par un moteur électrique, engageant l'arbre de transmission, caractérisé en que l'alimentation électrique du verrou passe par le contact repos d'un relais d'alimentation dont le contact travail commande l'alimentation des organes de commande du moteur du véhicule. These aims of the invention, as well as others which will appear later in this description, are achieved by means of a device for locking a transmission shaft of a motor vehicle, of the type using an electric lock. comprising a pole driven by an electric motor, engaging the transmission shaft, characterized in that the power supply of the lock passes through the rest contact of a supply relay whose working contact controls the supply of the control members of the vehicle engine.

Suivant une caractéristique importante de la présente invention, le relais d'alimentation est monté en série avec un interrupteur de fin de course<B>du</B> pene, ledit interrupteur n'étant fermé que lorsque le pêne est dégagé de l'arbre de transmission. According to an important feature of the present invention, the supply relay is connected in series with a limit switch <B> of the </ b> pole, said switch being closed only when the bolt is released from the drive shaft.

Selon une autre caractéristique remarquable de l'invention, le relais d'alimentation est en outre monté en série avec un interrupteur d'arrêt dont l'ouverture représentative de l'arrêt complet du véhicule. According to another remarkable feature of the invention, the power supply relay is also mounted in series with a stop switch whose opening representative of the complete stop of the vehicle.

Dans une variante d'exécution adaptée<B>à</B> un véhicule équipé d'une clé de contact, l'interrupteur d'arrêt<B>17</B> est du type normalement ouvert et sa fermeture est forcée par l'introduction de la clé dans une serrure de contact du véhicule. In an alternative embodiment adapted to a vehicle equipped with a ignition key, the stop switch <B> 17 </ B> is of the normally open type and its closing is forced by the introduction of the key in a vehicle ignition lock.

Dans une autre variante, adaptée<B>à</B> un véhicule sans clé, l'interrupteur d'arrêt est un relais normalement ouvert dont la fermeture est commandée par l'alimentation des accessoires du véhicule, ou encore directement par un calculateur contrôle d'accès du véhicule D'autres caractéristiques et avantages du dispositif suivant l'invention apparaîtront<B>à</B> la lecture de la description qui va suivre et<B>à</B> l'examen du dessin annexé dans lequel la figure<B>1</B> représente un schéma électrique du dispositif de verrouillage selon l'invention. In another variant, adapted to a keyless vehicle, the stop switch is a normally open relay whose closure is controlled by the power supply of the vehicle accessories, or directly by a computer. access control of the vehicle Other features and advantages of the device according to the invention will become apparent from the following description and the examination of the appended drawing in which the figure <B> 1 </ B> represents an electrical diagram of the locking device according to the invention.

On se réfère<B>à</B> la figure<B>1</B> dans laquelle la référence<B>1</B> désigne un verrou electrique (cadre en pointillés). Ce verrou comprend un moteur électrique<B>10</B> agissant un pêne<B>15</B> adapté pour verrouiller en rotation une colonne de direction 4 d'un vehicule automobile. Le pêne<B>15</B> est associé<B>à</B> un interrupteur de fin de course<B>16</B> représentatif de la position rétractée du pêne, c'est<B>à</B> dire que l'interrupteur de fin de course n'est fermé que lorsque le pêne est complètement dégagé de la colonne de direction et que celle-ci est libre en rotation. Bien entendu, la représentation schématique employée, sous forme d'un doigt coopérant avec une encoche, est pas limitative. Toute autre forme de verrouillage en rotation, par exemple bague cannelée coulissante coopérant avec des cannelures correspondantes sur la colonne direction, pourrait être employée de manière équivalente. Le moteur électrique<B>10</B> commandé par l'intermédiaire de deux relais<B>13</B> et 13'de type RT (représentés ici<B>à</B> l'état de repos), eux-mêmes commandés par une électronique de commande<B>11</B> agissant sur des transistors de commande 12 et 12'. L'électronique de commande<B>11</B> est reliée<B>à</B> une ligne d'alimentation commune<B>17</B> du verrou<B>1</B> par l'intermédiaire d'un transistor d'alimentation 14. L'une des bornes des bobines ainsi que le contact Travail respectif des relais<B>13</B> et<B>13'</B> sont également reliés<B>à</B> la ligne d'alimentation<B>17.</B> Le contact Repos des relais<B>13</B> et<B>13'</B> est relié<B>à</B> la masse électrique du véhicule. We refer <B> to </ B> the figure <B> 1 </ B> in which the reference <B> 1 </ B> denotes an electric lock (dashed frame). This lock comprises an electric motor <B> 10 </ B> acting a bolt <B> 15 </ B> adapted to lock in rotation a steering column 4 of a motor vehicle. The bolt <B> 15 </ B> is associated <B> with </ B> a limit switch <B> 16 </ B> representative of the retracted position of the bolt, it is <B> to < / B> say that the limit switch is closed only when the bolt is completely clear of the steering column and that it is free to rotate. Of course, the schematic representation used, in the form of a finger cooperating with a notch, is not limiting. Any other form of locking in rotation, for example sliding fluted collar cooperating with corresponding grooves on the steering column, could be used in an equivalent manner. The electric motor <B> 10 </ B> controlled via two relays <B> 13 </ B> and 13 'of type RT (represented here <B> at </ B> the state of rest) , themselves controlled by a control electronics <B> 11 </ B> acting on control transistors 12 and 12 '. The <B> 11 </ B> control electronics is connected to a <B> 17 </ B> common power supply line <B> 1 </ B> by the intermediate of a supply transistor 14. One of the terminals of the coils as well as the respective work contact of the relays <B> 13 </ B> and <B> 13 '</ B> are also connected <B> to </ B> the power line <B> 17. </ B> Relay Relay contact <B> 13 </ B> and <B> 13 '</ B> is connected <B> to </ B> > the electrical mass of the vehicle.

Le dispositif de verrouillage comporte en outre un relais d'alimentation<B>3</B> dont la bobine est reliée d'une part<B>à</B> une source de tension Vbat, en l'occurrence la batterie du véhicule, et d'autre part<B>à</B> la masse électrique par l'intermédiaire d'un interrupteur d'arrêt<B>5,</B> représenté ici sous la forme des contacts d'un relais normalement ouvert dont la bobine est branchée en parallèle avec l'alimentation des accessoires (autoradio, etc.) du véhicule, et de l'interrupteur de fin de course<B>16</B> du verrou<B>1.</B> Le relais d'alimentation<B>3</B> est du type RT et son contact commun est relié<B>à</B> la source de tension Vbat. Le contact repos R du relais d'alimentation<B>3</B> est relié<B>à</B> la ligne d'alimentation<B>17</B> du verrou tandis que son contact travail T est relié<B>à</B> la borne +APC (alimentation après contact) du véhicule. Classiquement, cette borne +APC alimente les organes de commande (non représentés) du moteur du véhicule, tels que relais de démarreur, allumage, injection, pompe<B>à</B> essence, etc. The locking device further comprises a supply relay <B> 3 </ B> whose coil is connected on the one hand <B> to a voltage source Vbat, in this case the battery of the vehicle, and on the other hand <B> to </ B> the electrical ground via a stop switch <B> 5, </ B> shown here in the form of normally relay contacts open, the coil of which is connected in parallel with the power supply of accessories (car radio, etc.) of the vehicle, and the limit switch <B> 16 </ B> of the lock <B> 1. </ B > The power relay <B> 3 </ B> is of the RT type and its common contact is connected <B> to the voltage source Vbat. The rest contact R of the power relay <B> 3 </ B> is connected <B> to the <B> 17 </ B> power line of the latch while its working contact T is connected <B> to </ B> the terminal + APC (power supply after ignition) of the vehicle. Conventionally, this terminal + APC powers the control members (not shown) of the vehicle engine, such as starter relay, ignition, injection, pump <B> to </ B> gasoline, etc.

On a également représenté sur la figure<B>1</B> un calculateur de contrôle d'accès 2 dont la fonction, connue en soi par exemple du document FR 2<B>759 109,</B> est de permettre, après reconnaissance d'un organe d'identification d'un utilisateur autorisé, l'accès au véhicule (verrouillage<B>/</B> déverrouillage des portières) et son utilisation. Classiquement, ce calculateur 2 est connecté en permanence<B>à</B> la source de tension Vbat et peut commander l'alimentation +ACC des accessoires du véhicule. Dans le dispositif selon la présente invention, ce calculateur de contrôle d'accès 2 est adapté pour transmettre<B>à</B> l'électronique de commande<B>11</B> du verrou des ordres de verrouillage<B>/</B> déverrouillage de la colonne de direction. Avantageusement, le calculateur 2 peut comporter une ligne de commande du transistor d'alimentation 14 de l'électronique de commande<B>11.</B> FIG. 1 also shows an access control computer 2 whose function, known per se for example from the document FR 2 <B> 759 109, </ B>, is to allow, after recognition of an identification body of an authorized user, access to the vehicle (locking <B> / </ B> unlocking doors) and its use. Conventionally, this computer 2 is permanently connected to the voltage source Vbat and can control the supply + ACC of the vehicle accessories. In the device according to the present invention, this access control computer 2 is adapted to transmit <B> to </ B> the control electronics <B> 11 </ B> of the lock of the lock commands <B> / </ B> Unlocking the steering column. Advantageously, the computer 2 may comprise a control line of the supply transistor 14 of the control electronics <B> 11. </ B>

On va maintenant décrire le fonctionnement du dispositif de verrouillage de colonne de direction selon l'invention. Le véhicule étant<B>à</B> l'arrêt, colonne de direction verrouillée, le pêne<B>15</B> est en position engagée dans la colonne de direction et l'interrupteur de fin de course<B>16</B> est ouvert. La bobine du relais d'alimentation<B>3</B> n'étant pas alimentée, le contact du relais<B>3</B> est en position repos R et donc la ligne d'alimentation<B>17</B> du verrou est reliée<B>à</B> la source de tension Vbat. Lors<B>de</B> la détection d'un accès autorisé au véhicule, ou d'une demande de mise en service du moteur, le calculateur de contrôle d'accès 2 commande le transistor d'alimentation 14 de l'électronique de commande<B>11</B> et transmet<B>à</B> celle-ci un ordre de déverrouillage de la colonne de direction. En parallèle, le calculateur 2 commande la mise sous tension du circuit d'alimentation des accessoires +ACC, ce qui a pour effet, dans l'exemple représenté, d'activer le relais de l'interrupteur d'arrêt<B>5</B> et donc de fermer les contacts correspondants.<B>A</B> réception de l'ordre de déverrouillage transmis par le calculateur 2, l'électronique de commande<B>11</B> agit sur le transistor de commande 12 pour activer le relais de commande<B>13.</B> Le contact de celui-ci passe en position Travail, connectant ainsi l'une des bornes du moteur<B>10 à</B> la source de tension Vbat, via la ligne d'alimentation<B>17</B> et le contact repos R du relais d'alimentation<B>3.</B> L'autre borne du moteur<B>10</B> étant reliée<B>à</B> la masse par le contact du relais<B>13'</B> resté inactif, le moteur entre en rotation et rétracte le pêne<B>15.</B> Une fois ce dernier complètement rétracté, l'interrupteur de fin de course<B>16</B> se ferme, refermant ainsi le circuit d'alimentation de la bobine du relais d'alimentation<B>3. A</B> cet instant, le contact du relais d'alimentation<B>3</B> passe en position travail T, permettant d'une part l'alimentation +APC des organes de commande du moteur du véhicule et donc sa mise en route, et supprimant d'autre part l'alimentation du verrou<B>1</B> en déconnectant le contact repos R et donc la ligne d'alimentation<B>17</B> de la source de tension Vbat. Le verrou électrique<B>1</B> n'étant plus alimenté, le relais de commande<B>13</B> est désactivé, les deux bornes du moteur<B>10</B> sont en court-circuit<B>à</B> la masse et le moteur<B>10</B> est arrêté. The operation of the steering column locking device according to the invention will now be described. With the vehicle <B> at </ B> the stop, steering column locked, the bolt <B> 15 </ B> is in the engaged position in the steering column and the limit switch <B> 16 </ B> is open. Power supply relay <B> 3 </ B> coil is not energized, relay contact <B> 3 </ B> is in the R rest position and thus the power supply line <B> 17 < The lock is connected to the voltage source Vbat. When <B> of </ B> the detection of an authorized access to the vehicle, or a request for commissioning of the engine, the access control computer 2 controls the supply transistor 14 of the electronics command <B> 11 </ B> and transmits <B> to </ B> it an order to unlock the steering column. In parallel, the computer 2 controls the power supply of the accessory supply circuit + ACC, which has the effect, in the example shown, of activating the relay of the stop switch <B> 5 < / B> and thus to close the corresponding contacts. <B> A </ B> receipt of the unlock command transmitted by the computer 2, the control electronics <B> 11 </ B> acts on the transistor of command 12 to activate the control relay <B> 13. </ B> The contact of the latter switches to the Working position, thus connecting one of the terminals of the motor <B> 10 to </ B> the voltage source Vbat, via supply line <B> 17 </ B> and the rest contact R of the power relay <B> 3. </ B> The other motor terminal <B> 10 </ B> being connected to the ground by the contact of relay <B> 13 '</ B> remained inactive, the motor rotates and retracts the bolt <B> 15. </ B> Once the latter completely retracted, the limit switch <B> 16 </ B> closes, closing the circu power supply relay coil <B> 3. At this moment, the contact of the supply relay <B> 3 </ B> goes to working position T, allowing on the one hand the supply + APC of the control devices of the engine of the vehicle and therefore its start-up, and on the other hand suppressing the supply of the latch <B> 1 </ B> by disconnecting the resting contact R and therefore the supply line <B> 17 </ B> of the voltage source Vbat . The <B> 1 </ B> electric lock is no longer powered, control relay <B> 13 </ B> is disabled, both motor terminals <B> 10 </ B> are shorted <B> to </ B> the mass and the engine <B> 10 </ B> is stopped.

Ainsi, une défaillance électrique susceptible de se produire dans l'electronique de commande<B>11</B> ou un ordre erroné de verrouillage de la colonne de direction ne peut avoir aucun effet. De même, tant que le pêne<B>15</B> est pas complètement rétracté et la colonne de direction libérée, il est impossible de commander le démarrage ou de permettre le fonctionnement du moteur du véhicule. Thus, an electrical failure that may occur in the control electronics <B> 11 </ B> or an incorrect steering column lock order can have no effect. Similarly, as long as the bolt <B> 15 </ B> is not fully retracted and the steering column released, it is impossible to control the starting or to allow the operation of the vehicle engine.

obtient ainsi, par la fonction<B>"OU</B> Exclusif" réalisée par le relais d'alimentation<B>3,</B> un dispositif de verrouillage de colonne de direction offrant une sécurité de fonctionnement renforcée. thus obtaining, by the <B> "OR </ B> Exclusive" function performed by the power relay <B> 3, </ B> a steering column locking device offering enhanced operational safety.

Lorsque le véhicule est arrêté, et que par exemple, le calculateur de contrôle d'accès 2 détecte un ordre de verrouillage des portières du véhicule, ou une disparition de l'organe d'identification de l'utilisateur, il commande l'arrêt d'alimentation +ACC des accessoires. Le relais de l'interrupteur d'arrêt<B>5</B> est alors desactivé, l'interrupteur d'arrêt<B>5</B> s'ouvre, interrompant l'alimentation de la bobine du relais d'alimentation<B>3.</B> Le contact de ce dernier repasse alors en position repos R, alimentant <B>à</B> nouveau le verrou électrique<B>1</B> et coupant l'alimentation +APC des organes de commande du moteur du véhicule. Le calculateur de contrôle d'accès 2 peut alors commander le verrouillage de la colonne de direction, par l'intermédiaire de l'électronique de commande<B>11</B> qui active le relais<B>13'.</B> Le moteur<B>10</B> est alors alimenté par sa seconde borne et déplace le pêne<B>15</B> de manière<B>à</B> engager la colonne de direction 4 et la verrouiller en rotation.<B>A</B> l'issue du verrouillage, le calculateur 2 peut commander le transistor d'alimentation 14 pour désactiver l'électronique de commande <B>11</B> du verrou et ramener celui-ci dans un mode stable de repos en position verrouillé. When the vehicle is stopped, and that for example, the access control computer 2 detects a door lock order of the vehicle, or a disappearance of the identification member of the user, it controls the shutdown of the vehicle. supply + ACC accessories. The relay of the stop switch <B> 5 </ B> is then deactivated, the stop switch <B> 5 </ B> opens, interrupting the power supply of the relay coil of power supply <B> 3. </ B> The contact of the latter then returns to the rest position R, supplying <B> to </ B> again the electric lock <B> 1 </ B> and cutting the power supply + APC engine control members of the vehicle.
